Our company is specialized in the production of vacuum pump manufacturers, production of various models of vacuum pump, 2BV, 2be and other models and specifications are complete. Vacuum pumps are widely used in many industries. Next, I will introduce the lower vacuum pump in detail.
Vacuum pump is a kind of device or equipment that uses mechanical, physical, chemical or physical chemical methods to extract air from the container to obtain vacuum. Generally speaking, vacuum pump is a device which can improve, produce and maintain vacuum in a closed space by various methods. Common vacuum pumps mainly include dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, rotary vane pump, roots pump and diffusion pump. There are many kinds of them. These pumps are essential main pumps in the application of vacuum technology in various industries of national economy.
The function of vacuum pump is to remove gas molecules from the vacuum chamber, reduce the gas pressure in the vacuum chamber, and make it reach the required vacuum degree. Generally speaking, there is a large range from atmosphere to extremely high vacuum. So far, no vacuum system can cover this range. Therefore, in order to meet the requirements of process index, working efficiency and equipment working life of different products, different vacuum system configuration needs to be selected for different vacuum sections. In order to achieve the best configuration, the following points should be considered when selecting the vacuum system:
First of all, the vacuum degree required by each process must be checked and determined. Because each process has its suitable vacuum range, it must be carefully studied and determined.
On the basis of determining the vacuum degree required by the process, check the limit vacuum degree of the vacuum pump system, because the limit vacuum degree of the system determines the best working vacuum degree of the system. Generally speaking, the limiting vacuum degree of the system is 20% lower than the working vacuum degree of the system, and 50% lower than the limiting vacuum degree of the previous stage pump.
Check and determine the type and volume of air extraction required by the process. Because if the kind of pumped gas reacts with the liquid in the pump, the pump system will be polluted. At the same time, it is necessary to determine the appropriate exhaust time and the amount of gas produced in the process of extraction.
Check and determine the time required to reach the required vacuum, the flow resistance and leakage of the vacuum pipeline. After the required vacuum degree is reached, the air extraction rate required to maintain vacuum under certain process requirements is considered.
