Pump Sealing Common Leakage Phenomenon and Countermeasures
The application of centrifugal water pump is very common in daily life, and its leakage problem has also become a very concerned problem for many people. Centrifugal water pump leakage mainly includes external leakage and internal leakage.
External leakage refers to the leakage from all parts of the external force, mainly from the connection of the turbine, the connection of the pump body, the connection of the pipeline and the connection of various accessories. One of the common leakage problems is that the sealing performance of the joint surface is not good. This kind of leakage is mainly due to the wrong installation of the turbine shaft and the spool, and the improper selection of the sealing structure of the spool, the installation method of the turbine and the improper choice of the spool structure. In order to improve the sealing effect, we should pay attention to the choice of sealing material and seal structure.
The biggest difference between centrifugal water pump and centrifugal pump is the direction of medium flow. Because of its special structure, there is a larger gap between the impeller and the volute, so there is potential for air leakage and cavitation. To prevent air leakage and cavitation, we should pay attention to the selection of medium for centrifugal pumps, the adjustment of pump operation parameters and the implementation of maintenance measures.
Internal leakage is caused by the lack of inner space of the centrifugal pump, which is a more difficult problem than external leakage. Generally, it is caused by the looseness of fixed parts inside the pump, the damage of gasket, the aging of sealing material and the deformation or fracture of impeller. In order to solve this kind of leakage, we should choose the proper gasket and reliable fixing parts, and do a good job in the installation of sealing parts, so as to ensure the good pressure and seal effect of each component.
In summary, for the leakage of water pump, we should pay attention to the installation, selection and maintenance of all components, and take corresponding measures in time. Only by doing this can we ensure the reliable performance of the centrifugal pump, thus ensuring the effective operation of the working system.
To sum up, effective measures should be taken to avoid common leakage problems of pump seal. First of all, we must pay attention to the selection of various materials and accessories, to ensure the reasonable collocation of materials and accessories. Secondly, we must pay attention to the correct installation and adjustment of seals, and pay attention to the maintenance and repair of the seals at ordinary times, so as to avoid the aging or fracture of the seals. Thirdly, we must pay attention to the selection of proper gasket, so as to ensure the sealing effect between the sealing surfaces. Finally, attention should be paid to the selection and maintenance of fastening parts and the reasonable collocation of oiling parts. Hope the above can provide reference for your choice of centrifugal pump seal.
