Water ring vacuum pump can start without water
Thread Content
What are the consequences of insufficient working fluid supply in a water ring vacuum pump? What happens in extreme cases, that is, when it is started without any working fluid? Please offer some advice! ! !
A liquid ring vacuum pump relies on the eccentric centrifugal motion of the working fluid as its power source; it has specific requirements regarding the flow rate and temperature of this working fluid, as a lower volume naturally results in less work being done.
Based on the principle of water ring vacuum pumps, it is clear that the amount of sealing fluid is very important. The amount is too small, resulting in poor efficiency ； When the amount is too large, the load increases and vibration occurs. However, if the mechanical seal is self-cooling, starting it without seal fluid will damage the seal; but if the seal has its own flushing fluid, operating without fluid for a short period should be fine. :handshake
Supported; the details are quite thorough. When there is little sealing fluid, starting up is only possible if there is insufficient vacuum, as the requirements cannot be met. However, if its amount decreases during use, it is possible for the remaining sealing fluid to be drawn back into the system. Therefore, the amount of sealing fluid should be slightly higher.:) This post was last edited by smlx1978 on 2008-9-22 at 21:42.]
Thank you all for your guidance; I think I have now obtained the explanation I wanted. :lol :handshake
A water ring pump can be started without water; water can be added gradually, and the amount of water used should be adjusted according to the level of vacuum. The pump should be put into use once a sufficient vacuum has been achieved. An excessive or insufficient thickness of the water ring in the pump affects the vacuum level!
The clearance inside the water ring pump should be maintained at around 15–25 microns. It requires water for lubrication and cooling during operation; running it without water can very likely cause the unit to burn out. We have encountered this situation before: the water circulation was under automatic control, but due to a fault in the flow meter, the automatic valve closed, and the water ring pump stopped receiving water. By the time it was discovered, the pump body had already turned red hot, with the impeller and distribution plate fused together, and the motor’s relay protection hadn’t even had time to activate
What was said upstairs makes sense: a short-term lack of liquid in the vacuum pump may reduce its efficiency and cause increased vibration, but it is still functional. But it cannot be without fluid for too long
By the way, a short-term lack of liquid won’t have a significant impact, but if it continues for a long time, it may damage the motor – as the heat generated by the pump has nowhere to go
