How to control vacuum degree of vacuum pump under abnormal condition Many vacuum pumps have no function of adjusting vacuum degree. Only by adding valves. For example, a precision pressure relief valve is arranged at the suction end of the vacuum pump. When the vacuum degree is high, open the val...

The vacuum pump shall be determined according to the local power supply. Where there is three-phase power supply, the three-phase pump shall be selected generally. This is because the same specification of single-phase pump and three-phase pump, vacuum pump volume is small, light weight, light vi...

The manufacturer of water ring vacuum pump analyzes the causes of the failure of vacuum pump in the paper factory, which are mainly reflected in the following aspects: 1. Pump body vibration When the vibration of the water ring vacuum pump body is too large, the vibration of the air inlet and exh...

The paper industry is one of the ten pillar industries of the national economy in developed countries. At present, the development of China’s paper industry has entered a period of rapid growth, and the paper industry has become a hot industry in China’s economic development. Papermak...

The application effect of rotary vane vacuum pump in the production process of diketene, the advantages of rotary vane vacuum pump and the concept of diketene are discussed. In the production process of diketene, the use of rotary vane vacuum pump is obviously superior to other vacuum pumps. The ...

Sealing problem 1. For static seal, there are only two types of seal: gasket and seal ring, and seal ring is widely used. For dynamic seal chemical pump, packing seal is rarely used. Mechanical seal is the main mechanical seal, and there are single end face and double end face. Balanced type and ...

Vacuum pump features (1) There is a large pumping speed in a wide pressure range; (2) The rotor has good geometric symmetry, so the vibration is small and the operation is stable. There is clearance between rotors and between rotors and shells, no lubrication, small friction loss, which can great...

No matter how good a machine is, it will encounter a “strike”. At this time, it is necessary to understand what happened to it and solve it, so as to better recover to normal work without working methods. 1、 Why does the vacuum pump fail to work? The vacuum pump will fail to work dur...

At present, the products concerned by the vacuum industry are mainly dry vacuum pumps. This kind of performance and other advanced equipment has a great influence in foreign countries. From the perspective of the overall development of the products, it is also very suitable for the production and...
