The compressor is a complex machine running at high speed. It is a basic requirement to ensure that the crankshaft, bearing, connecting rod, piston and other moving parts of the compressor are fully lubricated to maintain the normal operation of the machine. Therefore, the compressor manufacturer requires the use of lubricating oil with specified brand and regular inspection…

Overheating fault occurs at the friction points between crankshaft and bearing, crosshead and sliding plate, packing and piston rod, etc. The temperature exceeds the specified value, which is called overheating. The consequences of overheating: one is to accelerate the wear between friction pairs, and the other is that the heat of overheating continues to accumulate, causing burning…

Generally speaking, the operator can identify the abnormal noise of the compressor. The clearance between piston and cylinder head is too small, causing direct impact; The connecting nut between the piston rod and the piston is loose or tripped, the piston moves up in series and collides with the cylinder head, and metal chips fall into the cylinder…

If the pressure is abnormal and the amount of gas discharged by the compressor can not meet the user's flow requirements under the rated pressure due to the reduction of the exhaust pressure, the exhaust pressure must be reduced. The reduction of the required exhaust pressure is a phenomenon, and its essence is that the exhaust volume can not meet the user's requirements.…

Theoretically, the factors affecting the increase of exhaust temperature include intake air temperature, pressure ratio, and compression index (for air compression index K=1.4). The actual conditions affect the high suction temperature, such as low intermediate cooling efficiency, or water scaling in the intercooler…

After the dust or impurities in the atmosphere are filtered out by the air inlet filter, the air enters the compressor host through the air inlet control valve. During the compression process, the air is mixed with the injected cooling lubricating oil. The compressed mixed gas is discharged from the compression chamber into the oil gas separation tank. At this time…
