After entering the 21st century, the sustainable development strategy puts forward higher requirements for resource and energy conservation and environmental protection, so the rational utilization of organic solvents becomes increasingly urgent and acute. Solvent production and use enterprises c...

In the vacuum evaporation process on the market, the vacuum pump is often used for the concentration of traditional Chinese medicine, the synthesis of Western medic ine and the washing of Western medicine. The commonly used vacuum pump type is water ring vacuum pump. In order to understand the sp...

The practical application of the water ring vacuum pump system in the white water degassing system has achieved a good effect. At the same time, it also reflects the gradual development of the vacuum equipment in China. Water ring vacuum pump system will be more and more widely used in the future...

The concept and type of vacuum system, which I believe has been known by many users, is used to obtain the vacuum degree with specific requirements. There are three types: low vacuum system, medium vacuum system and high vacuum system. On these two points, EVP vacuum pump manufacturers do not wan...

I think you have a certain understanding of all aspects of liquid ring vacuum pump, and there are some more in-depth issues to discuss with you. 1. After the first sand spray of liquid ring vacuum pump and natural air drying, continue to apply industrial glue (silicon dissolving slurry) on the su...

While ensuring the safe operation of the vacuum pump, we should also pay attention to the energy saving and consumption reduction of the vacuum pump. The vacuum pump realizes that it is necessary to reduce the industrial water consumption and power consumption of the vacuum pump. 1、 Reducing wat...

Two aspects should be paid attention to according to different vacuum pump models According to the above criteria, when the vacuum degree or gas pressure required by the vacuum pump is not high, it can be preferentially selected in the single-stage pump. If the vacuum degree or exhaust pressure i...

What should be considered when selecting a vacuum pump? The function of vacuum pump is to remove gas molecules from the vacuum chamber, reduce the gas pressure in the vacuum chamber, and make it reach the required vacuum degree. Generally speaking, there is a large range from atmosphere to extrem...

At present, there are two types of vacuum pumps used in the water reverse osmosis treatment system in Shanghai: piston vacuum pump and centrifugal pump. These two types of vacuum pump technology are relatively mature, have been in the RO desalination system mature application. China is a country ...

The original vacuum pump system of extraction unit is steam jet pump. This kind of vacuum pump has many advantages but many disadvantages. It is a high energy consumption equipment only from the point of view of steam consumption (400kg / h); the steam condensate becomes oily sewage, and the sewa...
