The use of laboratory vacuum pump is more and more widespread, most laboratory equipment will be equipped with vacuum pump, because the vacuum pump is not a single equipment, it can be used with other instruments. For example, vacuum filtration, microbial detection, waste liquid extraction, rotar...

About several common connection forms of vacuum valve, EVP vacuum pump manufacturer will introduce relevant contents for you. If you have any questions, please feel free to contact us! 1. Flange connection This is the most commonly used connection form in vacuum valves. According to the shape of ...

vacuum bellows concept The so-called vacuum bellows refers to the axisymmetric tubular shell, whose generatrix is corrugated and has certain bendability, so it is also called flexible pipe or flexible pipe. Because of its geometric characteristics, the bellows can change its axial length under th...

Y-type vacuum flapper valve of working principle The high vacuum manual baffle valve can be used as the opening and closing mechanism in the high vacuum pipeline, which can cut off and connect the air flow in the vacuum system. The driving parts are screw driven lifting valve plate, which is ligh...

1. Why can’t the double seal valve be used as a cut-off valve? The advantage of the two-seat valve core is the force balance structure, allowing large pressure difference, and its prominent disadvantage is that the two sealing surface can not at the same time good contact, resulting in larg...

When purchasing vacuum equipment, we should not only pay attention to the quality and performance of the equipment, but also pay attention to the installation of the equipment in the actual application process. Correct installation can not only improve the working efficiency of the water ring vac...

Through the past understanding, vacuum pump is widely used in chemical, petroleum, mining, machinery and other industries. In addition, do you know that vacuum pump can also be used for vacuum transportation? We know very little about the content of vacuum conveying, but what we can think of is t...

How to solve the wear phenomenon of micro particles in liquid ring vacuum pump Due to the universality of liquid ring vacuum pump, liquid ring vacuum pump is also widely used in the application of pumping dust or conveying dust. Dust transport, especially the use of liquid ring vacuum pump in fin...

The start-up and operation of water ring vacuum pump is inseparable from the configuration of power supply. If the power supply is not stable or directly blocked, the vacuum pump will not be able to run, and the work progress will be delayed. Of course, its power configuration is not only power o...

The application rate of vacuum pump is more and more common. In the process of operation, the appropriate operation mode will be selected, and the advantages in the use process are more and more. In order to better application, let’s understand the antifreeze measures of vacuum pump. The o...
