With the continuous development of industrialization, baidu vacuum pump has gradually entered our life, how much is a vacuum pump everyone clear? The price of vacuum pump from several thousand yuan to tens of thousands of yuan or ten yuan are different, the working efficiency of the vacuum pump models or vacuum pump factors that affect the price, vacuum pump of choose and buy, can’t separate just see the price, we should consider the machine configuration, performance characteristics, working efficiency and after sales service and warranty time.
Vacuum pump price is too cheap, our machine performance is not guarantee, especially low price the quality of the machine is not high, may use no questions at the time, but after a period of time, certainly will find that the performance of the machine itself is not guarantee, in order to unnecessary maintenance cost, we will guarantee the quality of our machines, can’t separate covet is cheap to buy cheap machine.
Vacuum pump selection basis and conditions
(1) system requirements for vacuum
According to the requirements of the system on the vacuum degree, select the corresponding limit vacuum pump. It is generally required that the ultimate vacuum of the vacuum pump is 0.5~1 order of magnitude higher than the ultimate vacuum required by the system.
(2) pressure range during normal operation of the system
The pressure range required for normal operation of the vacuum pump shall meet the operating pressure required by the system.
(3) the type, composition and impurity of the gas being pumped as well as the limitation requirements for pollution during system operation
The nature of the gas being pumped and the requirements for pollution are important conditions for selecting vacuum pumps with different characteristics. It is not only related to the performance of the vacuum pump, and directly related to the pump’s working life and maintenance, especially in chemical production, it is often a key factor in the correct selection of the vacuum pump.
(4) the volume or volume flow of the system being pumped
It is the main basis for choosing a certain type of vacuum pump.
