Basic knowledge about using vacuum pumps

The operation of general vacuum pump equipment is relatively simple,

and most normal production processes do not require excessive manual operation. 

If the operator finds any abnormal conditions in the vacuum pump, in order to prevent accidents, 

the power should be cut off immediately and repairs should be reported in a timely manner. 

During use, avoid direct sunlight and keep away from heat sources. In daily work, 

equipment should be checked and maintained daily to ensure that there is no dust or debris, 

and to prevent debris from entering the pump.

1、 When the vacuum pump is operating normally, the following items should be checked every three days:

Is the pump oil within the range of the cursor? 

Is the pump oil turning yellow, black, or turbid? 

Is there any abnormal sound? 

Is there any oil leakage during the operation of the vacuum pump?

2、 If the vacuum pump filters the metal mesh, it should be opened weekly for cleaning and filtering of impurities.
 When the filter cannot filter out impurities, the filter and sealing gasket need to be replaced.

3、 Regular maintenance instructions for equipment: 

As the pump operates poorly, the degree of contamination and viscosity of the pump oil need to be identified through the oil window,

 and the pump oil needs to be replaced in a timely manner.

Cycle for replacing pump oil: Replace and clean the oil every six months. 

The steps for replacing pump oil are as follows: 

open the suction pipe of the pump and let it start running after 5 seconds. 

The remaining pump oil in the pump is easily drained.

Remove the exhaust pipe first, then open the oil valve, and pour out the pump oil.

Close the oil drain valve and inject new vacuum pump oil from the filling port.

If the pollution of the pump oil is very serious, some new pump oil must be added and cleaned by running for a few minutes. 

If the cleaning is not done properly once, it must be repeatedly cleaned several times.

After replacing the pump with new oil, turn on the pump and wait for the temperature to rise before confirming the vacuum limit pressure.

The maintenance process requires cleaning the filter screen.

4、 Operating instructions: 

The vacuum pump generates high temperatures (40-80 degrees) during long-term operation. 

Therefore, after operation or just stopping, do not touch the surface until the motor and pump body have cooled to normal temperature.

In case of emergency during work, immediately turn off the main power and provide warranty solution.

If the equipment is abnormal, it should be stopped immediately. Forced injection and forced operation are prohibited.

Non maintenance personnel are strictly prohibited from disassembling vacuum pump components.

The cloth strips and scraps used for maintenance and upkeep of equipment should be placed in designated storage areas

to prevent debris from entering the pump.
