Compressor pressure and abnormal sound

Compressor pressure and abnormal sound

Factors affecting the increase in compressor discharge temperature are intake air temperature, pressure ratio, and compression index. The failure of the compressor is also caused by several reasons. This article mainly describes the situation of abnormal pressure and abnormal sound.

The amount of gas discharged from the compressor with abnormal pressure cannot meet the flow demand of the user under the rated pressure, and the exhaust pressure must be reduced. I had to change another machine with the same exhaust pressure and a large exhaust volume. The main reason for the abnormal pressure between the stages is the leakage of the gas valve or the leakage of the piston ring. The reasons and measures should be taken from these aspects.
An abnormal sound compressor will give an abnormal sound if some components fail. Generally speaking, the operator can distinguish abnormal sounds. The clearance between the piston and the cylinder head is too small and directly impacts; the piston rod and the piston connecting nut are loose or tripped. The end face of the piston is blocked, and the piston moves up against the cylinder head; the metal fragments in the cylinder and the accumulated moisture in the cylinder can make a knocking sound in the cylinder. Crankshaft bolts, nuts, connecting rod bolts, crosshead bolt loosening, tripping, breaking, etc. in the crankcase, the shaft diameter is seriously worn, the clearance is increased, the clearance between the crosshead pin and the bushing is too large or the wear is serious, etc. A percussion sound is heard in the crankcase. The venting valve piece is broken, the valve spring is soft or damaged, and the load regulator is improperly adjusted, etc., and the knocking sound can be emitted in the valve cavity.

The actual situation affects the factors of high suction temperature, such as: low intermediate cooling efficiency, or the scale connection in the intercooler affects heat exchange, the inhalation temperature must be high, and the exhaust temperature will be high. The gas valve leaks and the piston ring leaks, which not only affects the rise of the exhaust gas temperature, but also changes the interstage pressure. As long as the pressure ratio is higher than the normal value, the exhaust gas temperature will rise. In addition, water-cooled machines, lack of water or insufficient water, will increase the temperature of the exhaust.
