How to check the rotary-vane vacuum pump oil level? - - - - - -

rotary vane vacuum water pump to remove the dry gas in the sealed container. If the installation of the town gas, it can also remove a certain amount of condensable gases. However, it does not apply to take out high oxygen content, corrosive to metal, chemical reaction of gas and dust sucker. So, how do you check the rotary-vane vacuum pump oil level? Let us introduce!

check rotary-vane vacuum pump oil level. Oil level should be located in the heart of the rotary-vane vacuum pump oil level of. The oil level is too low, can't seal the exhaust valve and vacuum degree. If the oil level is too high, will cause the fuel injection at startup.

1, before start the rotary-vane vacuum pump, please remove the v belt, motor for correction, and then start to avoid fuel injection.

2, in the process of operation, the oil level rose slightly, this is normal phenomenon. When the oil is insufficient, please use the vacuum pump oil from the oil-way. Need to filter the oil to prevent foreign body into the oil hole and jams. If the solenoid valve connected to the rotary vane vacuum pump port, it should be with the pump running at the same time.

3, when the rotary-vane vacuum pump starts, should use the start button at twice, so that the oil pressure in the pump chamber to tank, and then the official start of the run. When high environmental temperature, rotary vane pump oil temperature rise, high viscosity, higher saturated steam, which will result in lower ultimate vacuum. Should strengthen the ventilation and heat dissipation. Before stop rotary-vane vacuum pump, please close the intake valve to make it from the vacuum system, then stop and examine the limits of the rotary-vane vacuum pump vacuum pump. Squeezed vacuum gauge should be used. Vacuum gauge should be directly connected to the rotary vane vacuum water pump port. In running 30 minutes, will reach the highest degree of vacuum.

4, the operation of the rotary-vane vacuum pump. Check whether the vacuum pump oil is near the oil level line. Don't too quickly when you start the pumping system, open the valve, in order to avoid a large number of jet fuel. In the running process should pay attention to the abnormal noise and sound, should immediately stop when the pump oil overheating, so as to avoid pumping or wear.
