The core adaptation principle of vacuum pump selection Scenario matching is the first principle of vacuum pump selection

Different industries and different processes have very different requirements for vacuum pumps. There is no universal "optimal model", only solutions that best suit the scenario.

First of all, it is necessary to clarify the properties of the extracted gas, such as whether it contains corrosiveness, flammability, dust particles, and condensable steam. If it is an acidic gas extraction scenario in the chemical industry, you need to choose a corrosion-resistant vacuum pump with anti-corrosion treatment for the flow-through parts; if it is a sterile production process in the pharmaceutical industry, you need to choose a sanitary-grade vacuum pump with no dead ends in the inner cavity and that meets GMP certification standards.

Secondly, it is necessary to match the vacuum degree and pumping speed requirements of the process. Pay attention to whether the process requires ultimate vacuum or working vacuum. A 10%-20% margin needs to be reserved for the pumping speed, but there is no need to pursue high parameters excessively, otherwise it will cause unnecessary waste of energy consumption. In the process of serving a number of manufacturing companies, Hainan Zhijie Hengke Technology Co., Ltd. has encountered cases where customers chose a vacuum pump that was 2 orders of magnitude higher than the actual demand in order to "reserve sufficient margin", and the final energy consumption exceeded the standard by 40%. After targeted adjustments to the selection plan, the company's annual energy consumption cost was reduced by nearly 300,000 yuan.

Also consider the limitations of the installation environment, such as whether there are explosion-proof requirements, noise control standards, and the size of the installation space. These details will directly affect the use experience and compliance of the vacuum pump.
