Case analysis of low outlet flow of heavy oil pipeline pump related to seal failure
The customer reported the problem of insufficient pump flow, and someone needs to be sent to the site for repair
Zhejiang Huzhou some special material factory
The on-site inspection contents are as follows：
Pipeline pump transport very viscous belt particle dirty oil
处有少许不明显的泄露Slight leakage from the mechanical seal
KSB管道泵Etaline适用于这种复杂工况KSB pipeline pump Etaline is suitable for such complex working conditions
On site, the pump system was inspected and some necessary routine checks were made. It was found that the oil was very sticky, and the possibility of blockage of the pump pipe was large. But the oil came out slowly from the outlet plug, and there was no blockage.
Check the pump rotation, rotation is also correct, consistent with the pump rotation logo.
Final inspection found 3 pump mechanical seal leakage problem of the leak is different from the normal water pump, water leakage, because it is high viscosity oil, pump in running or stopping all the time can't see the big leaks, but a small leak diu diu, will cause when the pump is running, the air could be entering into the pump, to pump flow and low pressure.
