Suggestions for the use of screw air compressors!

Regarding the safety and stability of needle screw air compressors, industry experts put forward the following suggestions:

1. The reliability of the motor and instrument is the guarantee of the safety door

(1) The motor of the screw compressor should have a protection level not lower than IP44 to avoid electric leakage due to conductive dust in the air, especially in underground and coal chemical industry, including dispersed graphite and other production environments, to prevent static fire and electric shock accidents.

(2) The exhaust temperature of the screw air compressor should not be too high. Although the exhaust temperature is too high to avoid the emulsification of the compressor oil, it will also accelerate the aging of the compressor oil, increase the energy consumption of the compression rate, and waste electricity.

2. A reliable minimum pressure valve is a must for safety doors

It is not uncommon for the minimum pressure valve of screw air compressor not to open because the valve core and the positioning sleeve are stuck. The sleeve gap is too small and the valve core and positioning sleeve are made of aluminum alloy of the same grade, which is prone to bite and other reasons.

3. Effectively grasp the key points of the safety door of the screw air compressor

(1) The fuel injection system should be natural and smooth, and there should be no valves that may cause fuel cutoff, including solenoid valves;

(2) The temperature switch, controller and electrical control cabinet of the compressor should be reliable, and products from qualified manufacturers must be used;

(3) The accuracy and reliability of temperature switches, controllers and electrical control cabinets should be checked regularly.

At first glance, these measures seem a bit excessive, but compared with energy saving and safety, the input-output ratio is dozens of times, or even hundreds of thousands of times higher. In the post-compressor era, compressors continue to create smiles for people, but on the other hand, are people and compressors not engaged in a game of energy saving and energy consumption, safety and danger?
