The cryogenic air separation nitrogen production equipment uses air as raw material, which is compressed and purified, and then liquefied into liquid air through heat exchange. Then, liquid oxygen and liquid nitrogen are separated through distillation to obtain high-purity nitrogen gas. Large gas production capacity, high nitrogen purity of the product, and can be stored in liquid nitrogen storage tanks, suitable for large-scale industrial nitrogen production.

In the air separation unit, low-temperature liquid is transported by centrifugal cryogenic pump. In order to ensure the reliable operation of the equipment, two sets of low-temperature pumps are generally equipped, one for use and one for standby. During normal operation, the main pump runs at full load, and the standby pump is in standby state under low load operation. Since the working medium temperature of cryogenic liquid pump is about -180°C, the working pressure is very high, and the pump body is installed in the cold box. When the pump fails, it is extremely difficult to maintain. Therefore, how to maintain the stable and reliable operation of cryogenic liquid pump is of great significance.
