In the manufacturing process of lithium ion battery, vacuum technology plays an important role in the process flow of slurry mixing, liquid injection, baking, etc. The quality of lithium battery is closely related to the design of vacuum system. The vacuum pump is the main equipment of the vacuum...

Regardless of the installation clearance of vacuum pump, as far as the installation clearance itself is concerned, we should pay attention to that it is not only an important parameter in the cooperation tolerance between parts, but also in other aspects, it will directly affect the function of v...

(1) Increase the starting power of the diffusion pump and shorten the pressure transition zone when the mechanical pump switches to the diffusion pump. (2) Change the system operation process, and use valves to avoid the adverse flow danger zone (switching zone). For example, the high vacuum valv...

The vacuum pump unit is widely used in the production process of chemical enterprises. Because the production of chemical enterprises is accompanied by high temperature, flammable and explosive, corrosive gas, toxic and harmful substances, etc., the application performance of the vacuum pump unit...

In the process of using the pneumatic ball valve, its transmission shaft may be affected by the radial force, which may cause the use deviation. How to avoid the impact of the radial force on the transmission shaft of the pneumatic ball valve? Let’s take a look at the details. Pneumatic bal...

1、 It must be ensured that the mechanical part of the electric equipment of the electric butterfly valve has been commissioned and can work normally. For the commissioning of the mechanical part of the electrical equipment, please refer to the relevant application instructions. Install the devic...

With the development trend of industrial production, screw vacuum pumps have entered more and more manufacturing industries. In some years, leakage inspection of pump shells has also become a difficult problem, in order to prevent leakage from harming all mechanical equipment in normal production...

[Abstract] This paper analyzes the causes of the wear of the bearing position of the water ring vacuum pump and develops an effective on-site solution. The wear of the bearing position is solved by using the polymer composite technology. [Key words] Water ring vacuum pump; The bearing position is...

During the operation of the vacuum pump, due to air, foam is always generated, especially when there are externally active additives in the oil, and foam is not easy to disappear. Foam produced in the application of lubricating oil will destroy the oil film, not only make the conflict surface sin...
