Troubleshooting of compensation oil pump for diaphragm compressor

Troubleshooting of compensation oil pump for diaphragm compressor

Diaphragm compressor because of its good sealing, large compression ratio, the compressed medium is not polluted, and thus is widely used in the chemical industry, energy and other fields. Users due to the lack of understanding of the maintenance of this equipment, so that in the use of some small problems in the process and helpless. The following is some simple troubleshooting of the compensation oil pump to talk about some personal views.

Compensation oil pump is the heart of the entire oil circuit system of the film compressor, which is to continuously transport the hydraulic oil needed to form the oil pressure. If it fails, the entire oil circuit system will be disabled. The main faults include:

1) The plunger of the compensation oil pump is stuck

Compensation oil pump is a plunger pump, and the coordination gap between the plunger rod and the sleeve is very small. If the hydraulic oil is used for a long time or the filter screen is damaged, the dirt in the hydraulic oil will enter the pump body, causing the plunger to jam. At this time, to clean the compensation oil pump to ensure that the plunger moves freely.

2) Compensation for the oil pump filter screen plug

Clean the filter

3) Clean in, oil exhaust valve steel bead stuck or seal damage

Clean in and oil valve, ensure that steel ball moves freely and kerosene leakage test, no leakage should be found within one minute.

The utility model is a pressure oil supply device for compensating the diaphragm compressor oil pump, which belongs to the diaphragm compressor technology field in the field of gas compression technology. Including oil suction pipe, rotor pump, drain pipe, oil supply pipe and compensation oil pump; the rotor pump is directly installed on the spindle of the diaphragm compressor, the crankcase, the other end and the rotor pump, the end of the rotor pump, the other end and the drain pipe, the other end and the compensation pump to ensure the normal filling amount of the diaphragm compressor.
