(1) The compressor speed reduction to reduce the exhaust volume: because the exhaust volume of the air compressor is designed according to a certain altitude, suction temperature and humidity, especially in high altitude installation must be strictly in accordance with the instructions for correct installation, every period (60 days or so) should detect the intake pressure and exhaust volume.
(2) Scaling and blockage of the intake filter reduces the exhaust volume, and the filter should be cleaned regularly.
(3) the cylinder, piston, piston ring wear serious, out-of-tolerance, so that the relevant gap increases, the increase of leakage, affecting the displacement. Belong to normal wear, need to replace wearing parts in time, such as piston rings. It belongs to incorrect installation and improper clearance. It should be corrected according to the drawings. If there is no drawing, experience information should be obtained.
(4) Check the tightness of the stuffing box and whether the stuffing box itself is qualified when it is manufactured; Secondly, in the installation, pay attention to the neutral piston rod and stuffing box center; Generally, lubricating oil is added to the stuffing box, which can play the role of lubrication, sealing and cooling.
(5) the influence of compressor suction and exhaust valve failure on the exhaust volume. This problem may be due to one is manufacturing quality problems, such as valve warpage; The second is due to the valve seat and disc wear serious air leakage. In daily testing, the flatness of the valve plate and the gap between the valve seat and the valve plate should be measured so that it is in the normal range.
(6) The spring force of the air valve is not well matched with the air force. The elastic force is too strong to open the valve disc slowly, the elastic force is too weak to close the valve disc in time, which not only affects the gas volume, but also affects the increase of power, as well as the life of the valve disc and spring. Check spring preload pressure and working pressure regularly.
