The reciprocating compressor has liquid in it, that is, liquid slugging. When it’s light, there is a knocking sound and the machine vibrates greatly. Park and clean up. The heavy connecting rod broke, causing scratches on the cylinder block; in some cases, the compressor was even destroyed – the damage was extremely severe.
If liquid is present in the reciprocating machine, it can cause the piston to collide with the cylinder head, damaging the inlet valve and causing the cylinder head gasket to loosen. It is essential to drain the separator drain before starting the machine, and to turn the crankshaft back and forth repeatedly.
The two people above are absolutely right; it is dangerous to have liquid in the compressor, as this can lead to liquid slugging and even more serious accidents. Because compressors are used to compress gases, and gases can be compressed – increasing their pressure through compression – liquids, on the other hand, cannot be compressed. When there is a large amount of liquid, the accidents mentioned on the second floor occur. So it is necessary to follow what was said on the 3rd floor: use the separator drain at the front of the vehicle before driving and turn the engine over repeatedly.
Agreeing to the above, it is also necessary to open the bottom valve of the outlet separation tank to drain the liquid.
The presence of liquid generally causes the compression ratio of the compressor to exceed the designed value; in our facility, the presence of liquid in the compressors led to damage to the crankshaft and bearing shells.
