How to choose a water ring vacuum pump for use as a pump to fill water in high-mounted installations?
Thread Content
The height difference between the water pump center and the water surface is about 2 meters. There are two raw water ring vacuum pumps, with a maximum pumping capacity of 18 cubic meters per minute; one pump was sufficient to meet the requirements in the past, but now both pumps need to be run for long periods of time. What’s going on? How about planning to replace them with two larger ones?
Are two connected in parallel? One unit is leaking; check the suction pipe valve and the pump itself
Is it the water ring vacuum pump being used? The vacuum pump has low efficiency; it may be a problem with the pump itself. What is the quality of the water used in the water ring? Has the impeller been checked?
Please check and confirm the rotor condition； Is the gap between the distribution plate and the pump cover meeting the requirements for use? ； Is the flexible valve plate damaged? ； Is there any leakage at the shaft seal? ； And whether there are any air leaks in the process pipelines, etc
The people upstairs have explained it in some detail; these are the reasons. Besides that, has the water temperature increased? If the water temperature remains unchanged, then it’s due to the reasons mentioned above
