As it known to all, water ring vacuum pump in the general case use water as working fluid, in the process of water into the discharge to achieve the purpose of pumping air into vacuum state, and in the process of water absorption into sent by the pumping action of the water hitting the wall, impe...

When developing modern screw vacuum pumps the reduction of energy consumption has been given a high focus— it is now at about the same level of established oil-sealed rotary vane pumps or rotary piston pumps. To energy savings through modern screw vacuum pumps, similar opportunities arise when us...

Introduction: JZJX series roots-rotary pump system contains ZJ series roots pump as main pump and single or double stage rotary vane pump as fore pump. It is an ideal machine to achieve for low or high vacuum degree. Besides, the whole system will match the connecting pipe, valve, electric cabine...

1. Open cylinder and installation (1) Before dismantling the cylinder. Discharge oil from the vacuum pump (including liquid ring pump, rotary vane pump , rotary piston pump ,oil diffusion pump, dry scroll pump and so on ) Manually rotate the fan belt, discharge may have been gathered in the vacuu...

Generally,the following major common problems will occurs while in vauum pump using: 1. vacuum pressure decreased; 2. high noise; 3.pump oil injecting; 4.oil leakage; 5.massive smoke from pump oil; 6.vacuum pump , such as rotary vane vacuum pump , rotary piston vacuum pump , dry scroll vacuum pum...

Due to contain a certain amount of water vapor in the atmosphere, so when the vacuum  pump working the suction air also contain some non-condensable gas and the mixture of permanent gas.This gas mixture is compressed within the pump exhaust process, if partial pressure of non-condensable gas pass...

Oil free dry vacuum pump (also referred to as dry mechanical pump) refers to the pump can began under atmospheric pressure extraction, but also will be pumping gas directly into the atmosphere, the pump cavity without oil or other work medium, and the ultimate pressure of the pump and oil seal ty...

With the rapid development of economy in our country, the vacuum pump industry in our country have also maintained the momentum of rapid growth, and realize the steady and continuous development. In its rapid development at the same time, the vacuum pump companies and users are constantly explore...

1, To bearing the body on a regular basis to join bearing lubrication oil or butter. 2, When using the water ring vacuum pump, screw vacuum pump under the first diversion screw pump body, filling water diversion.Especially for mechanical seal water ring vacuum pump (2 bv, 2 be) to start the motor...

1, What is vacuum? Vacuum system refers to the below atmospheric pressure thin gas state, the region is not an absolute vacuum. 2, What is vacuum?Under vacuum gas rare book degree, usually with “high vacuum degree” and “low vacuum”.High Vacuum degree means vacuum degree...
