How much does it cost to select explosion-proof medium pressure fans for sales

Selection of explosion-proof medium voltage fan

The all wind explosion-proof medium voltage fan is made of aluminum alloy material as a whole, and the motor is an explosion-proof motor with an explosion-proof rating of DIIBT4. The protection level reaches IP54, and the insulation level is F level. The explosion-proof standard complies with the provisions of GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1 General Requirements" and GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2 Explosion proof Type D", as well as IEC60079-1 and European standards.

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.

Introduction to Materials for Explosion proof Medium Voltage Fans:

The casing and impeller of the fan are made of high-quality aluminum alloy material, which is more sturdy, durable, and reliable. Apart from the impeller, there are no other moving parts in the fan, and the impeller is directly connected to the motor, without gears or transmission belts. Therefore, it has high reliability, almost maintenance free, oil-free, pollution-free, and does not come into contact with anything when the impeller rotates. It is free of lubrication, ensuring no oil or gas, low vibration. The fan parts are precision deep processed, and the operating parts are designed, tested, and calibrated with extremely precise balance, so the vibration rate is very low.

Explosion proof fan ordering instructions:

When placing an order, it is necessary to indicate the explosion-proof level and clearly state the operating conditions.

2. The usage environment of voltage should also be clearly indicated.

3. In terms of gas extraction, it is necessary to clarify the degree of flammability or explosiveness of the gas and determine whether cooling measures should be taken.

If home delivery is required, it must be specified in the order in advance.

5. Generally, wooden boxes and cardboard boxes are used for packaging.

6. All production processes are carried out according to standard procedures and processes, including ordering, scheduling, material requisition, production, testing, packaging, inspection, and shipment, with a standardized traceability system to ensure the continuity of quality.

7. The general delivery time is 10-15 days. If it is urgent to use, advance payment must be made for booking to ensure the delivery time.

Small scale cast aluminum medium pressureexplosion-proofFan selection:

Explosion proof fan is a high-performance explosion-proof power air source equipment, made of aluminum alloy material as a whole. The motor is an explosion-proof motor, which will never produce sparks due to friction. It has better explosion-proof performance and is more reassuring to use. It has dual functions of blowing and suction, and can be used for both suction and blowing; Widely applicable to coal mines, oil and gas, petrochemicals, and chemical industries. In addition, it is widely used in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and medicine.
