Vacuum pump is one of the most difficult mechanical products in all pump series, because the level of vacuum directly affects the production process of users. This requires our manufacturers to assemble vacuum pumps in strict accordance with the specified size, careful and professional work, then how a qualified vacuum pump is produced? What are the key factors affecting the qualification of vacuum pump in the assembly process?

1. Casting quality

In order to let users understand the meaning more appropriately, let's give an example: for example, if we buy a good quality clothes, the fabric is a very important point affecting consumers. If the fabric is very rough and uncomfortable to wear, no one will buy any beautiful clothes. Just like our vacuum pump, the quality of casting directly affects the performance of our pump. If the customer is pumping corrosive gas, and there are sand holes or blowholes on the casting, these corrosive gases will slowly penetrate into every corner of the pump until all of them are corroded. Therefore, the quality of casting is a very important factor affecting the vacuum pump.

2. Professional level of skilled workers

When the material of clothes meets our needs, the style of clothes is the most attractive point for consumers. It is also a very depressing thing to meet a tailor who can't do clothes with excellent materials. Take our vacuum pump as an example, the professional ethics of technical workers is an important factor affecting the vacuum pump. If an excellent technical worker will assemble in strict accordance with the national standards, the fitting tolerance between assembly clearance parts is a very important parameter, which directly affects the performance of vacuum pump. Parts of the accuracy and poor fit will appear problems.

Taking water ring vacuum pump as an example, water ring vacuum pump is divided into single-stage water ring pump and double-stage water ring pump. The most important thing to pay attention to when assembling is to control the clearance between impeller and disc, which should be controlled between 0.1 ~ 0.3mm generally, and 0.3 ~ 0.5mm for large-scale pump.

3. Customer use

Good clothes should be worn by those who cherish it. After a qualified vacuum pump leaves the factory, the later use of customers is also crucial to the life of the vacuum pump. If the customer does not use according to the specified requirements, the service life of the vacuum pump will be greatly shortened.

Therefore, each vacuum pump in the process of using do not understand the problem, you can call the service hotline of the purchase company at any time, do not operate without authorization, so as not to cause greater losses!
