Single stage vane vacuum pump is a kind of vacuum pump commonly used in vacuum plasma cleaning machine. Due to the high working frequency and long service time of the single-stage rotary vane vacuum pump, it is necessary to carry out regular maintenance for the single-stage rotary vane vacuum pump according to the use requirements to avoid equipment failure due to long-term non maintenance. Today, we will introduce the maintenance methods and precautions of the vacuum pump of the single-stage spinner and plasma cleaner for your reference.
In daily use, we can regularly observe the oil level through the oil level window to determine whether it is necessary to add special vacuum pump oil, and confirm the color and state of vacuum pump oil by observing the oil level window and oil circuit circulating pipe. If the color of vacuum pump oil is deep or thick, the special oil and filter element of vacuum pump shall be replaced in time, the vacuum pump shall be cleaned and maintained.
Composition and maintenance object of single stage rotary vane vacuum pump
The routine maintenance of the single-stage rotary vane vacuum pump of the vacuum plasma cleaning machine mainly includes the mechanical pump room, air inlet, mechanical pump oil filter and vacuum pump special oil.
Maintenance process of single stage rotary vane vacuum pump
The maintenance process of the single-stage rotary vane vacuum pump of the vacuum plasma cleaning machine is as follows: remove the oil drain, clean the filter, clean the air inlet, clean the mechanical pump room, replace the oil filter, and replace the special oil of the vacuum pump
The first step of the maintenance of the single-stage rotary vane vacuum pump is to discharge the waste oil of the single-stage rotary vane vacuum pump. To drain oil, open the sealing cover of the oil port with a wrench, and then open the oil valve. When the vacuum pump oil in the oil tank is basically discharged, the inclined single-stage rotary vane vacuum pump can discharge more waste oil from the pump.
If the special oil of vacuum pump is dirty and sticky, it is difficult to release or discharge completely. More waste oil can be released as much as possible by pressurizing the oil injection port.
The second step of the maintenance of the single-stage rotary vane vacuum pump is to dismantle the filter of the single-stage rotary vane vacuum pump. To remove the filter, use a wrench to remove the fixing screw of the exhaust port, and then remove the cover plate of the exhaust port. At this point, you can see the oil filter. Finally, the oil filter can be taken out, and the oil filter positioning hole and oil return valve in the pump room can be seen.
Air inlet cleaning
The third step of maintenance of single stage vane vacuum pump is to clean the air inlet. If the air inlet of vacuum pump, it is necessary to remove the four screws of the air inlet, then remove the upper cover, then remove the connecting flange under the filter screen, then you can see the filter screen and check valve (both can be removed), and finally clean the filter screen and check valve with alcohol or oil and water.
Cleaning of single stage rotary vane vacuum pump chamber
The fourth step of maintenance of single-stage rotary vane vacuum pump is to clean the mechanical pump room. Clean the chamber of the single-stage rotary vane vacuum pump with a clean cloth (or absorbent paper, RAG) soaked with alcohol, oil and water remover. The waste oil in the cavity of single-stage rotary vane vacuum pump needs to be removed and the oil stain needs to be cleaned.
Oil filter change
The fifth step of maintaining the single stage rotary vane vacuum pump is to replace the oil filter. The oil filter is an infrequent replacement part. If regular maintenance is carried out, the spare parts can be replaced once a year. However, if the maintenance time of the mechanical pump is more than 6 months, and the pump is dirty or sticky, the oil filter needs to be replaced.
Replacement of special oil for vacuum pump
The last step of maintenance of single-stage rotary vane vacuum pump is to replace the special oil of vacuum pump. The vacuum pump special oil needs to close the drain valve first, then install the sealing cover of the drain valve, and finally add new vacuum pump special oil from the oil filling port. When adding special oil for vacuum pump, pay attention to the oil level window. Do not add too much special oil to the vacuum pump, otherwise it will leak when used.
