Installation method of rotary vane vacuum pump

The vacuum pump must be installed in a place with a clean environment and dry air. The room temperature should be between 5-40°C. The large pump must be fixed on a solid cement foundation with bolts.

Working principle of rotary vane vacuum pump

Rotary vane vacuum pumps are mostly small and medium-sized vacuum pumps. There are two types of rotary vane vacuum pumps: single-stage rotary vane vacuum pumps and two-stage vacuum pumps.

Application scope of rotary vane vacuum pump

The vacuum pump is suitable for vacuuming the closed system. Such as vacuum packaging, vacuum forming, vacuum suction.

Features of rotary vane vacuum pumps

A coarse filter with wire mesh is installed at the suction port of the vacuum pump. It can prevent solid foreign dust particles from being sucked into the pump chamber.

Structural description of rotary vane vacuum pump

The rotary vane vacuum pump is a positive displacement pump, which uses the rotary vane to continuously operate in the pump chamber to suck and compress the gas, and finally discharge it through the e

What factors are related to the shrinkage rate of rubber O-rings?

As a common sealing auxiliary accessory, the rubber O-ring is also crucial to the shrinkage of the rubber O-ring.

What should be paid attention to when using O-rings?

O-rings are widely used in various joints of hydraulic and pneumatic fittings, cylindrical surfaces and flange surfaces.

What is the reason why the O-ring is easy to break?

The O-ring is a small circle in the shape of an O, and it can also be made into other large sizes. In order to save costs, some manufacturers use inferior materials for production, so as to achieve th

What are the application ranges of O-ring seals?

As a kind of sealing ring with small size, simple structure and convenient disassembly, O-ring has its own advantages, so it has a wide range of applications. Many industries use O-ring.

Introduce the product advantages of O-ring seals

The structure size is small, easy to assemble and disassemble. Since the structure of the O-ring itself and the installation part are extremely simple and standardized, it is very easy to install and

Five main factors affecting the function of vacuum pumps

The influence of internal leakage: During the whole molten steel treatment process, the vacuum degree of the system is continuously increased with the reduction of the outgassing amount of molten stee

The main classification of PVC materials

According to different application ranges, PVC can be divided into: general-purpose PVC resin, high-polymerization PVC resin, and cross-linked PVC resin.
