Models VP-115, VP-125, VP-135, VP-145, VP-160, VP-180, VP-1100.
Suitable for maintenance, printing machinery, vacuum packaging, gas analysis, thermoforming and other industries for pumping operations, and can also be used as high vacuum equipment The backing pump is used..
When using vacuum pump, first remove the intake cap short.
Then check whether the intake cap at the connection of the air inlet and the side of the air inlet spare interface is tight, and whether the container and the pipe used are sealed, and there should be no leakage..
please use reliable way to extract the refrigerant from system. Note that taking out the refrigerant under high pressure will damage the body.
Selection of pump oil The type and state of the pump oil is in determining whether the pump can reach vacuum. In order to maintain the performance of the pump, we recommend that you use viscosity vacuum pump oil to facilitate the cold start of the pump..
Oil change degree To ensure that the pump is in hot state, the pump needs to run for about 1 minute open the air inlet at the time to force the in the cavity to flow out.
Turn off the switch and stop the pump and then open the plug to discharge the waste oil. When the oil stops flowing, tilt the body to discharge the residual waste oil Tighten the oil drain plug Open the trap and add new pump oil Cover the intake cap, start the pump and check the oil level after running for one minute.
Oil leakage 1 . Damaged oil seal, Replace oil seal 2 . Too much oil, Tighten the screws and replace O-ring.
Spray oil 1 . Too much oil, Drain the oil to the oil level line 2 . The inlet pressure is too high for time, Choose suitable pump and increase the pumping speed.
