Oil diffusion pump is often used in high-vacuum pumping system by  taking some technical measures, you can get ultra-high vacuum and  the method is: 1. choose a good performance diffusion pump oil Pump oil has a great influence on the ultimate pressure of the oil diffusion pump. Such as the use o...

PLAN 01 (Single-sided self-rinse) Description: The internal circulation from the outlet of the pump to the seal. Its operation similar to PLAN11. Reason: sealed chamber cooling; sealed chamber exhaust. Application: Single-end seals more be used for clean the transported fluid of viscous and easy ...

2XZ-C series of double-stage rotary vane vacuum pump is developed over years reaches by our special engineer team. The working process of 2XZ-C is: Rotor drives vanes to work in the surface of inside chamber, separate the inlet and outlet port and then drive gas out to create vacuum. 2XZ-C rotary...

Oil return is the biggest weakness of the oil diffusion pump, The return oil just only can be reduced and can’t be eradicated. In order to reduce the diffusion pump oil return, Finding out the main source and reason of oil return is necessary. Then thinking how to reduce the oil return rate. Part...

Lubricating the bearings Grease type , operating conditions Lubrication intervals of 4000 hours of operation each applyunder normal operating conditions and at ambient temperatures up to 40 ℃。 The regreasing intervals apply to normal loads, low-vibration running, approximately neutral ambient...

1.Simple introduction of Roots Vacuum Pump Roots vacuum pump, also known as mechanical booster pump, uses two eight-shaped rotor in the pump casing for synchronous rotation, so as to complete the process of inhalation and exhaust. Since main parts such as the pump casing, rotor and the end cap in...

1. Check the vacuum pump piping and the junction if have any loose phenomenon. 2. Adding bearing lubricating oil to the bearing body, oil level should be observed in the oil center line, the oil should be replaced or added timely. 3. Unscrew the pump body’s  water diversion plug and pour into wat...

Many users donot understand why there is oil smoke at discharge port of rotary vane vacuum pump after long term operation, here are potential reasons and suggestion: 1.Exhaust filter stop working Exhaust filter belongs to easy wear parts, which is used to separate oil vapor and gas to prevent oil...
