Why is the vacuum level of the propylene refrigeration compressor gradually deteriorating? How to solve it? The vacuum quality deteriorated without making any process adjustments
There are many factors that affect vacuum level, and these need to be analyzed based on the actual circumstances. 1 Steam quality, to prevent scaling in the turbine. 2 Steam pressure is high, the amount of air drawn out is low, and the amount of water returned is large. 3 Filter screen of the jet pump, jet steam pressure. 4 Whether the vacuum system is leaking. 5 Whether the rehydration condenser is fouled. 6 Pressure, flow rate, temperature, and direction of the cooling water. 7 Seal steam. The vacuum quality deteriorated without making any process adjustments. Has the steam system been checked?
