Dust/gas explosion-proof fanfeature：

1. It has dual functions of blowing and suction, and can be used for both suction and blowing;
2. Running with little or no oil, the output air is clean;
3. Compared to centrifugal fans and medium pressure fans, their pressure is much higher, often more than ten times that of centrifugal fans;
4. If the pump body is die cast as a whole and shockproof mounting feet are used, the requirements for the installation foundation are also very low. It can even operate normally without fixing the feet, which is very convenient and saves installation costs and installation cycles;
5. Compared to similar fans, its operating noise is lower, just like our company's introduction of the * - type vortex fan:
6. Maintenance free use; Its consumable parts are only two bearings, which basically do not require maintenance within the warranty period;
7. The mechanical wear of the vortex blower is very small because there are no other mechanical contact parts besides the bearings, so the service life is naturally very long. As long as it is under normal operating conditions, 3-5 years is no problem;
8. Easy to install and convenient to use;
9. The overall material is made of aluminum alloy, and the motor is an explosion-proof motor, which will never produce sparks due to friction. It is more reassuring to use and has better explosion-proof performance.

Gas high-pressure explosion-proof fanExplosion proof blower configuration:

1. Material of the casing: The explosion-proof high-pressure fan is made of * degree die cast aluminum. Compared to ordinary aluminum alloy, die cast aluminum is more sturdy, and compared to iron shell fans, it has a more lightweight effect.

2. Motor performance: The explosion-proof fan adopts an explosion-proof motor, which is a wideband, wide voltage motor. It is included in industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted from 45-75HZ, and the IP55 protection level is F-class insulation level. Its advantageous process is highly favored by domestic and foreign customers.

3. Fan oil seal: The explosion-proof high-pressure fan oil seal material is made of rubber and can withstand temperatures ranging from -25 ℃ to 300 ℃. Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan.

4. Fan bearings: The core components of the explosion-proof high-pressure fan use branded bearings, which can withstand a temperature of 350 degrees Celsius and a speed of 4000 revolutions per minute. Stable performance, low noise, maintenance free, longer lifespan, ensuring longer fan operation.

Methods for maintenance and upkeep of explosion-proof fans:

1) The motor of the explosion-proof high-pressure fan is directly connected to the impeller and belongs to high speed. The bearings need to be regularly maintained with grease to prevent damage (including the bearings of the impeller).

2) The shaft power and pressure of a motor are directly proportional. To prevent long-term extreme pressure from increasing shaft power and overloading the motor, a pressure relief valve is often used. It is an unloading valve. When the operating pressure of the high-pressure fan exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure and protect the motor of the high-pressure fan.

3) The internal mechanism of the high-pressure fan is relatively tight, with a small gap between the impeller and the casing, so it is necessary to filter out debris and dust. Usually, a fine filter screen/filter is installed at the air inlet. It often uses filters with different filtration accuracies according to different usage scenarios.

4) In some special occasions, special protection is also necessary: for example, when using in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose explosion-proof fans that allow for higher intake temperatures.

Explosion proof high-pressure fanInstructions and Conditions for Use and Installation:

Before installation, it is necessary to familiarize oneself with the various technical requirements in the manual, check whether the accompanying accessories are complete, and whether various technical documents are complete.

2. Conduct a preliminary inspection of the blower to ensure that there are no inorganic parts damaged during logistics transportation or long-term storage, whether there are any debris falling into the fan flow channel, and whether there is corrosion. Then use tools to rotate the fan spindle or the fan motor tail fan blades to see if the rotation is flexible and if there is any rubbing noise. Otherwise, the fault should be eliminated first.

3. According to the foundation diagram, the anchor bolts should be properly positioned. When installing the fan, the horizontal plane should be corrected to prevent excessive tilting.

4. The diameter of the pipeline should be slightly larger than the fan outlet diameter (the ratio of pipeline diameter to fan outlet diameter is 1.1:1), and the length of the pipeline should be shortened as much as possible. Elbows should be used sparingly, and the angle of the elbow should be greater than 90 degrees. It is not allowed to use right angle T-shaped joints. The joints of the pipeline should be tightly sealed and not leak, in order to reduce pressure loss. The weight of the pipeline shall not be supported by the fan, nor shall the fan be forcibly connected to the pipeline to prevent increased vibration and noise.

5. According to the characteristics of the blower, regulating valves can be installed at the inlet or outlet of the blower. Adjustment of air volume and pressure.

To protect the fan motor, a current overload protection device should be installed.

7. Close the air inlet of the fan, try starting the fan, and check if the main shaft rotation of the fan is correct. Then restart the fan and gradually open the regulating damper to the desired operating point after normal operation. However, the motor current should not exceed the rated value. If the desired operating point happens to be the fan's surge point, the operating point should be adjusted appropriately to avoid the surge point or other anti surge measures should be taken.
