The cause of insufficient compressor displacement

The cause of insufficient compressor displacement Insufficient exhaust volume is one of the faults that compressors are prone to occur. Its appearance is mainly caused by the following reasons: 1. The failure of the intake filter: clogged fouling, which reduces the exhaust volume; suction The pipe is too long and the pipe diameter is too small, resulting in an increase in suction resistance which affects the amount of air. Clean the filter regularly. 2. The reduction of the compressor speed reduces the discharge volume: the air compressor is used improperly, because the discharge volume of the air compressor is designed according to a certain altitude, suction temperature and humidity, when it is used above the above standards When on the plateau, the inspiratory pressure is reduced, etc., the exhaust volume is bound to decrease. 3. The cylinders, pistons, and piston rings are severely worn and out of tolerance, which increases the relevant clearance and leakage, which affects the exhaust volume. When it is normal wear and tear, it is necessary to replace wearing parts, such as piston rings, in time. If the installation is incorrect and the gap is not suitable, it should be corrected according to the drawing. If there is no drawing, experience information can be obtained 4. The packing box is not strict, and air leakage occurs to reduce the air volume. The reason is firstly that the packing box itself is unsatisfactory when it is manufactured; secondly, it may be due to the poor alignment between the piston rod and the center of the packing box during installation, resulting in air leakage due to wear and strain; generally, the filling box is filled with lubricating oil , It can play the role of lubrication, sealing and cooling. 5. The influence of compressor suction and exhaust valve failure on the exhaust volume. Metal debris or other debris falls between the valve seat and valve disc of the air valve, resulting in inadequate closing and air leakage. This not only affects the exhaust volume, but also affects the changes in interstage pressure and temperature; this problem may be due to one is manufacturing quality problems, such as valve warpage, etc., and the second is due to serious wear of the valve seat and valve disc Instead, an air leak is formed.
