The water ring vacuum pump keeps tripping – how to fix it?
Thread Content
The liquid level in the pre-pump separation tank is high, causing the water ring vacuum pump to trip constantly. How to solve this issue?
The problem description is not comprehensive enough. Did it occur during testing or after the unit had been running for some time? If it happened after running for a while, it is recommended to check whether the pump casing is scaled; it is also necessary to examine the trip current to determine whether the shutdown was caused by overload or by electrical issues
It might be a vehicle jump caused by overload. This situation needs to be investigated from the following aspects. 1. Check from the process perspective: process parameters such as the amount of working fluid, liquid level, and the opening degree of the inlet valve ； 2. Check from the mechanical properties of the equipment: scaling, jamming, balance, etc ； 3. Check the electrical system: for issues such as leakage current and motors. . .
Why can’t the liquid level in the pre-pump separation tank be controlled? Poor drainage?
Under normal circumstances, a pump shutting down is mainly due to overload. You can check the mechanical conditions of the equipment: scaling, jamming, balance, etc； Check the electrical system: for issues such as leakage current and motors. . . There is another situation where there is a problem with the contacts of the pump’s start button.
Reply 2# lgf_1980: After the pump has been running for some time, the liquid level in the separator tank ahead of the pump rises, causing the pump’s flow control mechanism to trigger a shutdown! The liquid level in the separator tank before the pump is sometimes high and sometimes it can be emptied – why is that?
Check your vacuum tank top cooler to see if there is any leakage!
