Energy-saving air separation equipment

The water supply source of air cooling column in precooling system equipment is cooling water pump, and water cooling column is supplied by chilled water pump. Their structures and principles are described as follows: 1. Design structure: the most basic components inside the centrifugal pump are high speed impeller and fixed volute pump case. Generally, the impeller with several (4 ~ 12) backward curved blades is fixed on the pump shaft and driven by the motor to rotate with the pump shaft at high speed. The work done by these impellers will directly act on the liquid in the pump body, which is the energy supply source device of centrifugal pump. 2. Principle: after the centrifugal pump is started, the pump shaft directly drives the reverse curved impeller to move at high speed, squeezing the pre filled liquid between the reverse curved spaces of the blade to rotate. Under the high-speed centrifugal force formed by the movement of the pump shaft, the liquid moves radially from th

Due to improper adjustment of seal gas pressure during operation, liquid oxygen pump can not pump liquid or leak.   From the quality point of view, when the sealing pressure is too high, there will be gas leakage into the pump through the labyrinth seal, resulting in the impeller with gas or even idling, resulting in liquid injection or pressure drop; when the air pressure before sealing is too low, there will be liquid oxygen leakage.   From the quantity point of view, when (p1-p3...
