A mining company in Shanxi has been ordering vertical pipeline centrifugal pumps from our company for a long time to transport clean water underground. Recently, a customer reported that the pump was leaking and making abnormal noises. Due to the urgent need to use it on site, we arranged for technical personnel to inspect it. The pipeline centrifugal pump was used 600 meters underground in the mine,Technicians followed the customer to the bottom of the well for investigation,To determine the location of the water leakage, first check whether the pipeline is leaking, because considering the presence of cavitation in the pipeline, it is easy for water leakage to occur,Need to optimize operating parameters and replace new pipelines to solve the problem.After inspection by the technical personnel, it was found that it was not a pipe leak, but a leakage at the connection between the pump shaft and the pump cover. This situation needs to be investigated whether the leakage was caused by a damaged machine seal or O-ring gasket. After careful inspection, it was found that it wasLeakage caused by damaged O-ring, technicians immediatelyDisassemble and replace with new parts,The pump is running normally and the customer is very satisfied.
After solving the water leakage problem, the techniciansSubsequently, we also helped the customer inspect the dynamic and static rings inside the pump chamber, as well as other moving components such as impellers and bearings. These components are inevitably worn out after long-term use, and the more fine particles in the liquid, the faster the wear rate. If they cannot function properly after severe wear or aging, abnormalities will naturally occur. So it is recommended that customers also regularly check the overall condition of the pump and internal components. Finally, the technical personnel also reminded the customer to pay attention,Pipeline pumps excel in processing efficiency, but have limited adaptability to the medium and can only handle clear water liquids. If the liquid contains a large amount of hard particles, it may wear through the pump chamber and cause leakage,If the liquid to be transported has a high content of acidity or fine particles, stainless steel pipeline pumps can be used specifically and equipped with wear-resistant machine seals to maintain transportation stability.
As for how to deal with pipeline pump leakage, overall solving it is not complicated, after all, it is just one of the common reasons. Only personnel with basic maintenance knowledge can quickly handle it. For users, they should adhere to the correct operating method to avoid accelerating pump wear and tear.
