Nanguang vacuum

Because all sorts of vacuum pump performance in addition to all can be met on vessels vacuum suction in common besides, still have different. So in when choosing must be clear about the pump in the vacuum system of work undertaken tasks is very important, the pump in different field, the role of to sum up the main has the following respects

1) in the system makes pump

The Lord is on the vacuum pump system are pumping container directly, to get a vacuum in needed to meet the technological requirements of vacuum vacuum pump.

2) thick smoke pump

Thick smoke from the atmospheric pressure pump is to point to start reducing pressure vacuum system to another suction system can start to work in vacuum pump.

3) the former stage pump

The former stage pump that is used for the other a pump pressure in the former stage to maintain the highest level of the license before the vacuum pump pressure.

4) maintain pump

Maintain pump is when vacuum system suction very hours, not the effective utilization of main pump before class. Therefore, in the vacuum system in the other match a suction speed smaller auxiliary pump to maintain level before the main pump or maintain the normal work of the time needed for the container has low voltage vacuum pump.

5) thick vacuum pump or low vacuum pump

Thick, low vacuum pump is to point to start from the atmosphere, reduce the pressure of the containers are pumping after work in low vacuum or thick vacuum pressure within the scope of the vacuum pump.

6) high vacuum pump

High vacuum pump is to point to in high vacuum range of vacuum pump work.

7) ultra-high vacuum pump

Ultra-high vacuum pump is to point to in ultra-high vacuum range of vacuum pump work.

8) booster pump

Booster pump usually refers to work in low vacuum pump and the vacuum pump, to improve between high air extraction system in the middle pressure range of extraction flow or lower level before pumped gas rate requirements of the vacuum pump.

3.1.5 vacuum pump type and specification of said method

According to the law of the People's Republic of mechanical industry standard JB/T7673-95 regulation, domestic all kinds of vacuum pump is from the basic model and auxiliary type two parts, both for a middle passage. Its expression type for 123-456. In case number 123 basic model, said 456 said auxiliary type.

The model usually in domestic vacuum pump table 3-2 of the Chinese phonetic alphabet to said. If in phonetic alphabet prefaced by "2" word, it means the pump in the structure of double level on pump.

Some of the vacuum pump series air extraction rate criterion with geometric progression to fund. The unit is "L/S". Divided into 18 a level, were 0.2, 0.5, 1,,2,4,8,15,30,70,150,300,600,1200,2500,5000,10000,20000,40000. Vacuum pump series sometimes also can use the entrance of the pump size to said its unit is "mm". Because of the type of pump more, when choosing, should refer to different manufacturer's product instruction style, this is very important.
