1,The effect of the failure of the suction and exhaust valves of the compressor on the exhaust volume.

Metal fragments or other debris fall between the valve seat and the valve plate of the valve, resulting in lax closing and air leakage. This not only affects the exhaust volume, but also affects the inter-stage pressure and temperature changes, the emergence of this problem may be due to a manufacturing quality problems, such as valve warping, etc., the second is due to the valve seat and valve wear serious formation of leakage.

2、Constant temperature and humidity test box stuffing box is not strict, resulting in air leakage to reduce the gas volume.

The reason is firstly that the stuffing box itself is not required when it is manufactured; secondly, it may be due to the poor alignment of the piston rod and the stuffing box center during installation, resulting in wear, strain, etc., causing air leakage; generally filling the stuffing box Lubricating oil, it can play the role of lubrication, sealing and cooling.

The cylinder, piston and piston ring of the constant temperature and humidity test box are seriously worn and out of tolerance, which increases the relevant clearance and the leakage, which affects the displacement. In case of normal wear and tear, the wearing parts shall be replaced in time. If the installation is incorrect and the gap is not appropriate, it shall be corrected according to the drawings.
