In Plan 53B system, the pressure of the isolation fluid increases
Thread Content
In System 53B, the pump inlet pressure is 8 kilograms, while the pressure of the isolation fluid used for priming is 25 kilograms. During operation, the pressure of the isolation fluid in the pump can increase, reaching up to 35 kilograms. Number 10 white oil is used as the isolation fluid. It has been found that the accumulator has not been pressurized, and the exhaust valve was not opened when pre-pressurizing the isolation fluid.
First, the exhaust valve must be opened when priming with isolation fluid; otherwise, an \"air lock\" may form”； Check the temperature of the isolation fluid to see if an increase in temperature is causing the pressure to rise
