Explosion proof transparent medium pressure fan - medium pressure blower

Explosion proof transparent medium pressure fanTo provide more advanced, safer, and more reliable next-generation power equipment for industries such as coal, petroleum, and chemical. Explosion proof medium pressure blower is suitable for explosions caused by combustible gases or vapors and air%Places containing explosive mixtures; The protection level of the main body shell isIP54The protection level of the junction box isIP54The rated frequency is50HzThe insulation level of the motor isFGrade; It is very important to correctly select explosion-proof motors that are compatible with various equipment in environments with explosive hazards.

Characteristics of explosion-proof blower

1. The impeller is directly installed on the motor without contact compression, ensuring the high reliability of the machine even under large pressure differentials.

2. Adopting a wide voltage dual frequency (50/60HZ) motor with a protection level of IP54 (F).

External bearing design enables the fan to withstand high temperatures and improve its service life and reliability.

4. Oil free and water free compression.

5. Meet safety usage requirements in Europe, North America, Australia, and other regions, and obtain European CE certification.

The low noise of * * greatly improves the production environment for customers.

Equip special equipment for PetroChina, Sinopec, coal gas, and biogas with high-level safety protection fans.

Up to 60 models are available for you to choose from, and we can provide personalized products for any special needs you have.

Explosion proof transparent medium 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.
