How to choose water ring vacuum pump? - - - - - -

water ring vacuum pump is one of the common vacuum pump application, how to correctly choose water ring vacuum pump? Then look at together.

a, water ring vacuum pump types of clear

key by the types of water ring vacuum pumps are needed in the work of material, volume, vacuum, or exhaust pressure of work.

water ring vacuum pump after normal work, must pay attention to two points:

1, as far as possible provisions selected vacuum degree of vacuum pump in efficient segment, also is in the critical value the vacuum or operate critical value area of the exhaust pressure of work, it can ensure the vacuum pump can be in accordance with the standards and regulations of the must all work normally. Should prevent the large vacuum water pump vacuum or larger category of exhaust pressure around the operation. Operate in this area, not only high efficiency is extremely low, and the work is not very stable, very easy to make the vacuum pump to cause vibration and noise. Here, the vacuum degree of high vacuum pump area within operation, often will continue to produce cavitation condition, the significant condition of this kind of situation is caused by the vacuum pump with noise and vibration. Excessive cavitation can cause the pump shell, centrifugal impeller, such as the destruction of parts, so that the vacuum pumps can't normal work.

to be able to see, when the vacuum degree necessary for the vacuum pump or the air pressure is not high, have priority in single pump selection. If the vacuum degree or high exhaust pressure regulation, single pump is usually not to consider, or, regulation pump in a high vacuum condition still has great capacity, the regulation characteristics graph at higher vacuum degree is relatively flat, secondary pump can be used. If vacuum regulation in - Above 710 MMHG, can use water ring vacuum unit for vacuum packaging equipment.

2, on the basis of the system software need to choose appropriate containment vacuum pump

if selected after the types of vacuum pump and vacuum unit, also must be on the basis of the system software required to use appropriate containment specifications ( The vacuum technology of vacuum speed selection and vacuum time measure can refer to the separate companies product introduction) 。
