Effects of screw air compressor actual displacement factor

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

And the mechanical and electrical equipment company limited technical personnel for the effect of screw air compressor actual displacement factor has made concrete analysis:

The 1 device speed:

Screw air compressor exhaust volume and speed proportional to the rotational speed, and often varies with the voltage, frequency and change. When the voltage is decreased or reduced frequency, speed will decrease, so screw air compressor exhaust volume reduction.

In 2 condition:

Screw air compressor is a volume type compressor, air suction volume. When the suction temperature, or suction pipeline resistance is too large and the suction pressure is reduced, the gas density, a corresponding reduction of screw air compressor exhaust volume;

3 gas leakage:

Between the rotor and the rotor and casing in operation without contact, maintaining a certain gap, so will produce gas leakage. The high pressure gas through the gap to the suction pipe and is aspirated to tank leakage, will make the exhaust volume decrease. In order to reduce leakage, on the driven rotor tooth top seal teeth, driving rotor tooth root opening with a sealing groove, face processing is also a cyclic or strips of seal teeth. If the seal line wear, will make the leakage increased, therefore the maintenance of peace time should take these factors into account;

The 4 cooling effect:

The gas in the process of compression temperature will rise, rotor and shell temperature also increase correspondingly, so in the suction process, the gas is heated and the expansion of the rotor and the shell, so the corresponding reduction of inspiratory capacity. Screw type air compressor rotor some used the shell oil cooling, water cooling, one of its aims is to reduce the temperature. When the cooling effect is not HERSHEY'S, elevated temperature, screw air compressor exhaust volume will be reduced.

And the 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 ).
