The following is a summary of the common Four types of air compressor failures and the reasons for the analysis.

1. Abnormal pressure.

The air volume discharged by the compressor cannot meet the user's flow requirements under the rated pressure, and the exhaust pressure must be reduced.At this point, we have to replace the same exhaust pressure, and the big Air Displacement of the machine.The main reason for the abnormal pressure is the leakage of air valve or piston ring, so it is necessary to find the cause and take measures.

2. Abnormal temperature.

Abnormal exhaust temperature means that it is above the design value.The factors that influence the increase of exhaust temperature are: inlet temperature, pressure ratio, and compression index (for air compression index K=1.4).Actual situation factors affecting to breathe in high temperature, such as: the middle cooling efficiency is low, The incrustation scale in the middle cooler will affect the heat transfer, and the air suction temperature at the back will be higher and the exhaust temperature will be higher. In addition, air valve leakage, piston ring leakage, not only affects the exhaust temperature rise, but also can make the pressure change, as long as the pressure is higher than normal values will increase the exhaust temperature.The water - cooled machine, lack of water or water shortage will increase the exhaust temperature.

3.Abnormal sound.

If the compressor fails, it will make an abnormal noise. Generally speaking, the operator can distinguish the abnormal sound.Piston and cylinder head clearance too small, direct impact;The piston rod is connected with the piston to loosen or release the nut.The piston end face wire is theblocked, the piston moves up the collision cylinder head;In the cylinder, the metal debris and the accumulation of water in the cylinder can be tapped in the cylinder.Crankcase in bolt, nut, crankshaft connecting rod, crosshead bolt looseness, tripping, and broken, trunnion badly worn clearance increases, cross pin and bushing fit clearance is too large, or wear and so on, are available on the voice in the crankcase.The exhaust valve plate is broken, the valve spring is loose or damaged, the load regulator is not adjusted properly, etc., and the tapping sound can be made in the valve chamber.Find fault and take action accordingly.

4. Overheating fault.

In crankshaft and bearing, crosshead and skateboard, packing and piston rod and other friction, the temperature exceeds the specified number is called overheating.The consequences of overheating: one is to speed up the wear of the friction pair, and the second is that the heat energy of the heat accumulates continuously to burn the surface and cause a major accident of the machine.The main reasons for the overheating of the bearing are: the bearing and the shaft neck are not uniform or the contact area is too small;Bearing deflection crankshaft bending, lubricating oil viscosity is too small, oil road blockage, oil pump failure to cause broken oil, etc.When installing, there is no leveling. There is no gap between the main shaft and the motor shaft, and the two axes are tilted and so on.
