China's high-quality production of Roots blower

Roots blower is a positive displacement blower, there are two trefoil relative rotation of the impeller and the casing wall by sealing the space, since each impeller is involute or epicycloidal package envelope impeller processing line, three blades of each impeller are exactly the same, while two impellers are also identical, thus greatly reducing the difficulty of processing. When impeller machining CNC equipment to ensure that the center distance of two impellers in the same situation next, no matter what position the two impellers to rotate, can maintain a certain minimum gap, to ensure gas leak within the allowable range.

Two impellers rotated in opposite directions, due to the clearance between the impeller and the impeller, the impeller and the casing, the impeller and the wall between the minimum, so that the air inlet is formed a vacuum, into the intake air chamber under the atmospheric pressure, and then, wherein each of the impeller blades and the two panels, the chassis constitutes a sealed chamber, an air intake chamber during rotation of the impeller, the blades are formed by two seal chambers constantly brought to the discharge chamber, and because row gas chamber impeller are engaged with each other, so that the air is squeezed out between the two blades, so that a continuous non-stop operation, the air from the intake port steady flow delivered to the outlet, which is the Roots blower the entire work process.

High-quality Chinese-made centrifugal fan

. After the air flow into the fan axial impeller along the main radial flow. Such a centrifugal fan according to the principle of action made products, including centrifugal fan, centrifugal blowers and centrifugal compressors. Centrifugal fan is a complex structure of the equipment, the main air inlet valve, impeller, motor, the outlet composition. In different states, the effect of centrifugal fan is not the same. Therefore, different operating conditions partly dissenting, centrifugal fan effect will be affected. The centrifugal fan debugging to the best condition, can start from several aspects. 1, centrifugal fans allow full pressure start or step-down power, it should be noted that the current full voltage starting is about 5-7 times the rated current, voltage starting torque is proportional to the square of the voltage, when there is insufficient network capacity, should step-down start. 2, centrifugal fan during commissioning, should carefully read the product manual, check the wiring method if the same wiring diagram is consistent; should carefully check the supply fan power supply operating voltage is not meet the requirements, whether the power phase or same phase, electrical components are assigned capacity to meet the requirements. 3, the number of test less than two, one to control power, fans observed a man running, and found anomalies immediately stop inspection; First check the direction of rotation is correct; after centrifugal fan starts running, you should immediately check the operating current of each phase is balanced the current exceeds the rated current; if not normal, you should stop to check. After running for five minutes, the fan down to check whether there are anomalies, confirming that no anomalies and then start running. 4, two-speed centrifugal fan test, it should start low, check the direction of rotation is correct; must be stationary when starting the fan speed and then start to prevent high-speed reverse rotation, causing damage to the motor and switch tripping. 5, when the centrifugal fan up to speed, the fan should be measured input current is normal, centrifugal fan operating current can not exceed the rated current. If the operating current exceeds the rated current, should check the supply voltage is normal. 6, centrifugal fan motor power required is defined as the condition of the centrifugal fan and wind chassis, the required high power inlet fully open. If the air inlet fully open operation performed, the risk of damage to the motor. When the fan is best to test the fan inlet or outlet valve on the pipeline closed, the operation will gradually open the valve, until the desired working conditions, and pay attention to the fan operating current exceeds the rated current. When installing wind cabinet, subject to the following requirements: 1. When used for fire, the exhaust port and smoke machines should be interlocked, when any one of the exhaust ports open, smoke machine that is able to automatically start 2 The fan installation ambient gas entrained sticky substances, dust and hard particle content should not be greater than 150mg / m3. When the fire smoke is not required 3. Install the fan should have a damping device, install ceiling should be securely fastened. 4. When use power outlet, the fan power cable should be connected with compliance with safety standards plug; when the fan power cable is connected directly to the power line; power supply line should be fitted with a contact separation of at least 3mm all-pole power switch. Distribution should be installed motor protection devices. 7.5Kw motor should have more power down and start-up device.

We are Henan cents Run Fan Manufacturing Co., Ltd. We are professional do the fan manufacturers.

Environmental newly designed centrifugal fan

Xianrun has developed high pressure blowers-in-series systems to achieve static pressure, previously unachievable by single stage centrifugal blowers.


Series and parallel connected blower installations are often used to meet performance ranges beyond normal single stage blower capacities. For systems that require high ststic pressure, and especially high pressure TOGETHER with high temperature (where standard multi stage, positive displacement, screw, or regenerative type blowers can not be used) series of single stage centrifugal blowers can be used. Many times additional blower in the system can be advantageous. For instance, where two blowers are operating in series and one breaks down, the other may be able to "limp" the system along while the necessary maintenance is performed. Having on blower continue in operation can often allow limited production while the other is being repaired. Also, there are cases where having one blower continue in operation could prevent or at least minimize system or equipment damage from such things as high temperature ot contaminated airstreams.

Another advantage of blowers in series is that of the availbale space. If system must be expanded and increaases the CFM requirements, the allotted space for the original blower may not be large enough for a single large blower, but might be large enough to istall two smaller blowers in series to obtain the necessary pressure.
One more potentail advatage for series operation is the likehood of initial cost savings. Although each case must be evaluated individually, it is often more economical to select two "smaller" blowers with their respectice smaller motors and drives than to select one "larger" blower to do the job.

Series connected blowers are those which have the outlet of the one blower exhausting into the inlet of another blower. By connecting blowersa in such a manner, high static pressures can be attained. This is accomplished as the second blower adds its pressure capability to the system, increasing the capacity beyond the capabilities of the first blower.

Ideally, two identical blowers installed in series would result in the same CFM at the outlet of the second blower as the inlet of the first one, and nearly twice the static pressure as that rated for either blower alone. However, some variation will result in both air flow and combined pressure because of the tendency of air to compress under pressure. A good understanding of how atnoshperic pressure and absolute temperature affect density is required. Both of these factors are involved in the proper selection of blowers. Density is directly proportional to atmospheric pressure and is inversely proportional to absolute temperature (degrees Rankine).
Caution is necessary in selecting blowers for series installtion. It is generally accepted that most pre-engineered blowers are capable of withstanding twice their catalog rated static pressure. In other words, where two blowers are installed in series the second blower housing should withstand the higher pressure. There is, however, a need for concern when the combined pressure exceeds twice the rated static pressure for one blower. In series applications involving three or more blowers, or in any system in which positive or negative pressure exists prior to the consideration of the blowers, special housing reinforcement may be necessary.

Customer Fan Selection Method

In engineering or practical applications, a reasonable choice of fan is a very important job. Fan Once selected, it will run a number of years in the production and life, a reasonable selection will bring the user's convenience and efficiency. Fan selection principles are as follows.
1, before selecting fan, production and product quality should be aware of the market situation ventilators, such as ventilators produced varieties, specifications and a variety of special-purpose products, as well as departmental standards, national best products out of product, the new product development and promotion and so should take full account of environmental protection requirements in order to select the best fan.
2, depending on the fan conveying gas physical and chemical properties, select the fan for different purposes. Conveying explosive and flammable gas should be selected from the explosion-proof fan; row dust or transporting coal or pulverized coal should choose Dust fan; transport of corrosive gases should be chosen preservative fan; work in high temperature applications or conveying high temperature gas should be selected high temperature ventilators.
3, select the fan performance icon Richard have two or more fan when available, preference should be given a higher efficiency, smaller machine number, a large adjustment range, of course, should be compared, weighed pros and cons of a decision.
4, if the selected fan impeller diameter than the original fan impeller is too large a lot, in order to take advantage of the existing motor shaft, bearings and bearing, etc., must start time critical speed, strength and fan of the original components of the motor shaft etc. accounting.
5, the choice of centrifugal fan, when it is equipped with motor power less than or equal to 75kw, do not just start with the installation of the valve. When the carriage of high temperature flue gas or air and the choice of boiler centrifugal induced draft fan, which should be set up to use the valve to prevent operation when cold cause overload.
6, silencer required ventilation system should be first choice of high efficiency, low circumferential speed of the impeller fan, and make it work at maximum efficiency point; ventilation system should be based on modes of transmission of noise and vibration generated, take appropriate muffler and damping measures. Fan and motor damping measures, generally adopt damping base, such as a spring or shock absorber rubber shock absorbers.
7, the choice of fans, fans should avoid using parallel or series operation. When unavoidable, you should choose the same model, the performance of joint work with the ventilator. When used in series, the first stage should be a fan to a pipeline connection between the second stage fan.
8, the choice of new fans should consider the full use of existing equipment, suitable for on-site fabrication and installation and safe operation and other issues.

Axial Fans Description

Brief Description
Ordinary axial fan can be used for general factories, warehouses, offices, homes and other places within the ventilation, can also be used chillers (air cooler), an evaporator, a condenser, a spray-down, etc., are mine shaft flow fan,
Corrosion, explosion-proof axial fan using corrosion-proof materials and measures, and explosion-proof motor matching can be used to transport explosive, volatile, corrosive gases,
Gas delivery requirements axial fan should be no significant dust, non-sticky and fibrous substances; motor directly coupled to a temperature not exceeding 40 ℃, the belt drive type temperature does not exceed 60 ℃. The amount of conveying gas dust shall not exceed 150mg / m3,
Axial fan is mainly composed of the impeller, chassis, motor and other component parts, and the stent using steel casing duct connection. Wherein the anti-corrosion axial fan impeller, casing are made of glass and steel, other types of axial fans generally use steel.

Folding works
Energy when the impeller rotates, the gas from the air inlet axially into the impeller by the impeller blades push leaving the gas rises, and then flows into the vanes. Vanes will deflect the air flow into axial flow, while gas is introduced into the diffuser tube, further gas kinetic energy is converted to pressure energy, and finally to introduce the work of the pipeline.
Work axial fan blades and aircraft wings similar. However, the latter is to lift up the role on the wing and supports the weight of the aircraft, while the axial fan is fixed to the position and movement of air.
Cross-sectional axial fan generally airfoil. Blade position can be fixed, to be rotated about its longitudinal axis. Or blade pitch angle of the blades and airflow can be adjustable or non-adjustable. Changing the blade angle or pitch is one of the main advantages of axial fans. Small blade pitch angles produce lower flows while increasing the pitch may result in higher traffic.
Advanced axial fan blade pitch can be changed (which is quite similar to a helicopter rotor) during fan operation, thus changing the flow accordingly. This is called variable pitch (VP) axial fans.

Folding use
Axial fans called local fans, industrial and mining enterprises is commonly used as a fan, but it is different from the general fan motor and fan blade in a cylinder, the shape is a cylindrical shape, for local ventilation, easy installation, ventilation effect is obvious, safe, hairdryer lookout can be connected to the designated area.

Future trends fan

The fan industry has a long history, fans of national economic growth has made tremendous contributions. Fan products in the metallurgical, oil, petrochemical, refrigeration and other industries in various places and subway tunnels, marine and other countries has been widely used, mainly plays the role of ventilation. With the rapid growth of national economies, particularly efficient and environmentally friendly era, each state has increased infrastructure investment, and increased efforts to support the development of various industries, which is bound to stimulate the wind turbine market more prosperous. Chinese fan industry in the years of the development of continuous exploration, technology continues to improve, continuously enriched. So fan product development trend of the future is like?
First, to improve the efficiency of the fan is to adapt to the needs of a large industrial development trend
First, since the requirements of industrial production, the efficiency of the fan is the main direction of future development. Optimized turbine design structure, and strive to achieve the highest unit efficiency thereby expanding the adjustment range of the fan, so you can make the operating efficiency of the fan to get the maximum extent. This will be the fans companies need to increase research efforts to solve the problem.

Second, to reduce the volume of the fan, reduce the weight of the fan is to adapt to the trend of low-carbon environmental protection requirements
In improving the operational efficiency of the fan at the same time, reduce the volume of the fan, reduce the weight of the fan, so that products will get a broader market space. I believe that with the miniaturization of the latest technological achievements bearing industry applications, for fans of good design criteria.

Third, reduce the fan noise will run the fan favored by the market
Fan noise during operation generated by the equipment operator is a kind of labor damage, but in recent years, there is often a factory fan affect the normal life of the residents reported, so the future will be to reduce fan noise fan industry need to explore important subject.

Fan enterprises should grasp the development trend of the product at the same time, increase research investment, constantly optimize the design and performance of fan products, to the fierce competition in the market.

Cement plant for large industrial fans

Cement production enterprises of the national economy in the production of energy guzzler, the cement industry has been listed as one of the key areas of resource conservation. Under the State Council to speed up construction of a conservation-oriented society policy environment, improve conservation-oriented manufacturing and application level cement industry, cement industry, the establishment of conservation-oriented system is significant. In the current domestic and international energy supply and demand contradiction, the cement manufacturers must reduce energy consumption through a variety of ways to get the best value for money and the highest labor productivity. In cement production, motor load power consumption accounted for nearly 30% of the cost, and drag the fan motor with a high-pressure account for a large proportion in the motor for a cement production line of which 25% to 30% of the electricity is used drag the various types of fans, so do the work of saving efficiency blower motor becomes extremely important.

At present, many cement plant fan big horse car phenomenon is serious, while air flow due to the conditions, changes in production, the system needs also change, most of the fans using the traditional approach that adjustment, the outlet valve opening degree implementation, and the method is to increase wind resistance, sacrifice efficiency of the fan to meet the requirements of a serious loss. If the use of frequency control technology to change the speed of the device to adjust the size of the wind, it can not only satisfy the production requirements, but also to achieve energy savings, while reducing wear and tear caused by the deflector baffles and pipes and downtime often caused by Economic losses. With the development of power electronics technology and electronic technology, variable frequency technology matures, the international fan for air volume, air pressure adjustment has generally been abandoned by adjusting the throttle opening means supporting, and replacing them with variable-speed electric drive adjustment, variable frequency adjustment speed has become the best choice for electrical transmission scheme fans, pumps and energy saving.

In the cement plant fan frequency control technology, significant energy savings can be improved, improve production efficiency, cement plants bring great economic and social benefits. Depending on the fan experience a large number of cement production line of energy-saving high frequency control, after using frequency control, electric fan consumption decreased by 8% to 45%, electricity to 0.50 yuan / kWh basis, usually recoverable inverter 1.5 to 3.5 years equipment installation and other additional expenses, etc. the total investment.

2, high-voltage inverter in cement production line fan energy-saving applications and benefits

Frequency control technology is now used in various industries, smart VFD from 2005 onwards energy-saving motors used in the cement industry, has been successfully used in six positions process cement production line of high pressure fans, namely: raw mill circulating fans, coal mill circulating fan, kiln exhaust fan, high temperature kiln fan, kiln exhaust fan, cement mill circulating fan, and has made many successful transformation experience, access to significant economic benefits .

After the table is to select different types of high pressure blower frequency conversion transformation instantiated data saving test results in a fully loaded system, the same environment, the requirement under the process conditions:

Type of fan motor power voltage level adjustment block Bankai opening degree operating power (kW) operating current (A) operating frequency frequency-converted before saving rate frequency inverter raw mill cycle 630KW 6KV throttle 80% 50,037,225 36.5% 64 43 coal mill cycle 560KW 10KV throttle% 80% 50,038,224 372 437 kiln exhaust damper 710KW 6KV 70% 58,236,936 39.9% 70 34.8 kiln exhaust 1000KW 10KV water resistance 80% 84,071,015 39.7% 61 42.9 High temperature 2500KW 10KV circulating fluid coupling 90% 26,002,350 9.6% 15,514,345 cement mill cycle 355KW 10KV throttle 45% 19,010,545 6.2% 17 36

Of particular note is required to control the pressure in the preheater kiln dry cement production process kiln temperature circulating fan, need to be adjusted for the amount of hot air circulating fan through the DCS control, the original design generally use hydraulic speed control coupler, wound rotor string resistance velocity modulation, etc., but the basic trend is currently developed rapidly in the 1990s and in recent years has proven technology and performance of high voltage AC variable speed technology is far better than before speed mode adopted, after a large number of successful field application and shows its great energy efficiency, high-voltage inverter is a national cement energy conservation design standard equipment. In our October 25, 2007 promulgated mandatory standards since May 1, 2008 implementation of the "GB50443-2007 cement energy-saving design specifications," the provisions of paragraph 4.3.5: "The high temperature kiln fan should adopt frequency modulation speed means. "
