We know that the compressor compressor running without oil, the damage
to its own can not be reversed. This rule is also applicable to the
scroll compressor. In this paper, we will take Valley wheel
ZB38KQ-TFD-558 as an example to explain. First of all, the scroll
compressor internal oil long time will lead to overheating mechanism and
the side friction, sintering, lead to bearing axle; even for a short
time lack of oil can also cause the friction mechanism and lead to
abnormal wear, vibration, noise.

Take the wheel ZB38KQ-TFD-558 as an example, the circulation volume is
about 330kg/h under the ARI condition, and the compressor will
discharge a little refrigerator oil when the refrigerant is discharged.
Even if only 0.5% of the oil rate, if the oil can not return to the
machine through the system cycle, then in 50 minutes you can bring all
the oil out of the compressor, in about 2~5 hours, the compressor will
burn out.

Preventive measures: 1. Ensure that the refrigerator oil of the
compressor is returned to the press; 2, reduce the oil rate of the
compressor. (press starts frequently, which is bad for oil return) |
