[Asia Fluid Network News] Cryogenic pump is generally used in packing seal. So cryogenic pump seal cost more than other vacuum pumps. Cryogenic pump is mainly used in petroleum, chemical plant, it is used to transport liquid hydrocarbons, liquefied natural gas and refrigeration equipment, liquid oxygen, liquid nitrogen and other special gas pump. According to the functional structure, cryogenic pump can be divided into two major types. Cryogenic pump 1. Piston, plunger type of such cryogenic pump is mainly used in gas filling, chemical processes. For example, by adding high-pressure nitrogen, nitrogen dioxide and carbon dioxide to chemical reactors, gas is supplied to the steel-making furnace of metallurgical works as a conveying pump, and the flow rate is generally not large in centrifugal type, but can effectively provide gas pressure. 2. Centrifugal centrifugal cryogenic liquid pumps are typically used to transport liquid from a cryogenic liquid container to another container or as a process pump in space division. The pump is normally sealed using a mechanical seal or maze Sealing, etc., the sealing cost is relatively high. Cryogenic liquid pumps are machines that are used to pump cryogenic liquids and increase their pressure. Due to the safety of air separation plant and liquid storage and transport needs, with a corresponding low-temperature liquid pump, such as liquid oxygen pump used to circulate liquid oxygen or liquid oxygen from the sump, and delivered under the provisions of the pressure after vaporization user. According to the above analysis, we can understand that the characteristics of cryogenic pumps with different types have different characteristics, people can choose according to different needs of their own models. The premise is the need for cryogenic pump models have a certain understanding of the characteristics. As China's vacuum pump market continues to grow, now the type of cryogenic pump is bound to meet the demand, increase their types and models of research is a very necessary issue.
