Screw type air compressor pneumatic control components function description

( supply: Bengbu air compressor water heater, Bengbu air compressor waste heat recovery )

And the mechanical and electrical equipment company limited technical personnel for screw type air compressor system made specific analysis, the following give you for screw compressor gas path control unit function description.

The 1 vent valve:

When unloading operation or stops, the valve is opened, the release of oil and gas in the barrel pressure, so that the compressor low load operation, or in case of no load restart.

2 load solenoid valve:

Two two normally closed solenoid valve. Through the electromagnetic valve of electric and power loss, control gas road, off state, realize the loading, unloading function.

The 3 sensor:

Pressure, temperature sensor for measurement of various parameters and realize compressor plus, load shedding, various failure prompt, automatic stop when necessary.

4 proportion valve:

Exceeds a set pressure regulation act, the proportional valve ( namely system exhaust pressure ) is high, the output of the control pressure is low. While the control pressure is low, through the cylinder telescopic control inlet relief valve disc opening is smaller, the compressor air intake volume is small, the compressor of air supply and air consumption balance, to realize stepless capacity control function.

Set pressure regulating method:

Lift up the proportion valve black cap and rotation, clockwise, counterclockwise rotation pressure increases, decreases. Set up, pressing blocks, prevent it because of the vibration of rotating automatically. Set value should be less than the rated pressure, if higher than the microcomputer controller set unloading pressure, only the car without a capacity adjusting.

5 chronicles, and mechanical and electrical equipment Limited sincere intention to recommend air compressor water heater, air compressor waste heat recovery equipment, as long as you plant air compressor, can 0 operation cost system of water. Scope of supply: China (excluding Hong Kong and Macao ).
