Carbon dioxide stripping process ammonia pouring pump
Thread Content
During the carbon dioxide stripping method and pouring liquid ammonia pump, what is the reason for the high oil pump pressure of the ammonia pump? What are the hazards to the pump and system? How to avoid it? This post was last edited by 1025199692 on 2009-3-10 21:27 ]
Excuse me: Is it reciprocating or centrifugal?
Reciprocating, is it a crankcase or a gearbox? Is the oil pump running all the time? How does the oil pump pressure return to normal after starting operation? This post was last edited by Boating on Five Lakes on 2009-3-10 20:18 ]
1. The above situation may occur in either the crankcase or the gearbox. 2. High pressure will definitely have a certain impact on the pump. If the oil pump is too high, it will be overloaded or even trip. It will also have an impact on the ammonia pump. 3. The problem is not clear. Based on experience, after the ammonia pump is stopped, the oil temperature drops, the viscosity increases, and the oil pump pressure rises (because the pump needs a backup oil pump, it is still running) ； vice versa. measure: 1. Turn the pump upside down and proactively lower the oil pressure after stopping the original operating pump. ； On the contrary, increase the pressure. Usually 1-2KgZUOYOU
It's a gear. Indeed, as the friend Xing Xingtao said, the oil pump only alarms when the ammonia pump is stopped and the pump is stopped. I asked the operator and he said that the oil pump will alarm as long as the pump is stopped. I feel that this phenomenon is very abnormal. How can I avoid this phenomenon? ? Please give me any corrections! ! :handshake to add something: What can the central controller do? This post was last edited by Durian on 2009-3-12 00:54 ]
Yes! After the pump stops, the pressure will increase due to the temperature drop or the oil consumption in each oil channel decreasing due to the movement to stop!
