Cryogenic pump selection

【Asian Fluid Network News】 Cryogenic liquid pump is used to pump low temperature liquid and increase the pressure of the vacuum pump equipment. As its use continues to grow, buyers are focusing their attention on selecting products for attention: cryogenic pump assembly, venting, oil in the piping, moisture and air. Only by noticing these issues will consumers be more motivated in product selection. Next, the main introduction to the selection of cryogenic pump cryogenic pump need attention when: 1, cryogenic pump assembly parts are not allowed to stained with water and grease, parts must be washed with a solvent, and then dry assembly. Not only the pump itself to keep cold, pump suction line must also be cold measures to prevent in operation from the outside inhalation of heat, the liquid vaporization, affecting pump performance. 2, cryogenic pump and pipelines such as oil, moisture and air, when the access to low temperature liquid will freeze, so before the pump is put into operation to be cleaned, and then with a dry nitrogen scavenge, driven out of the pump Within the moisture and air, and pre-cooling. 3, the suction port of the cryogenic pump and the suction pipe should have exhaust, so that the pump in operation before or during operation to exclude the gradual accumulation of gas, to ensure the reliable operation of the cryogenic pump. 4, in the case of explosive gas, the motor should use vertical explosion-proof motor. Cryogenic transport can also be used cryogenic shielding pump. Cryogenic pump is a special pump used to transport liquid hydrocarbons, liquefied natural gas and liquefied gas in liquid nitrogen, liquid nitrogen, etc. in petroleum and chemical plants, so it is also called cryogenic pump. From the above analysis we can know that cryogenic pump parts are sensitive to water and other substances, cryogenic pumps need to install exhaust facilities and so on. Each product has its own characteristics, how to choose a high efficiency, affordable cryogenic pump, need to do a lot of homework. Cryogenic pump selection is not only the focus of consumer needs, it should also be manufacturers need to focus on the direction.
