What preparations need to be made before starting a CO2 cryogenic pump?

Before starting, check whether the pump’s inlet and outlet valves are open, whether the lubrication system is normal, whether the electrical connection is firm, and ensure that there is no residual gas or impurities in the pump body. When starting for the first time, use a low-temperature medium to fully precool the pump body to reduce the impact of temperature differences on the pump. At the same time, check whether key components such as pump seals and bearings are intact to ensure that the pump can operate safely and stably.
