Mechanical seal leakage is the most common
Pump failure fault, so the pump mechanical seal also belong to one of the vulnerable parts of the pump, if there is water seepage, how to deal with it? Pump mechanical seal Mechanical seal at the first possibility of water leakage is mechanical seal, static plane wear. The machine seal caused by static and static wear plane for five reasons: 1, the installation is too loose. Observer seal, static ring plane, the surface has a thin layer of scale, to wipe the surface of the basic wear and tear, which is caused by the loss of spring flexibility and poor assembly, or motor caused by the axial movement. 2, the installation is too tight. Observe the static and dynamic ring plane of the mechanical seal. If there is serious burning phenomenon, the surface is black and deep, the seal rubber hardens and loses its elasticity. This phenomenon is caused by the tight installation. Approach: Adjust the installation height, the impeller is installed, pull the spring with a screwdriver, the spring has a strong tension, release immediately reset, there are 2-4MM mobile distance. 3, poor water quality with particles. Due to poor water quality, containing small particles and medium hydrochloride content is high, the formation of abrasive wear seal plane or surface of the resulting groove, ring groove and so on. Approach: improve water pressure or medium, replace the machine seal. 4, dry running damage caused by running water. This phenomenon is more common in the end of the valve installation form the entrance of negative pressure, air inlet pipe, the pump cavity with air, pump boot, machine seal friction high speed operation produces high temperature, can not be cooled, check machine seal, spring tension normal , The friction surface burns black, the rubber hardens and cracks. Approach: drain pipes and pump cavity air, replace the mechanical seal. 5, cavitation. Cavitation is mainly caused by hot water pump. As the medium is hot water, the water temperature is too high to produce steam, the gas inside the pipe into the pump chamber height, this part of the gas can not be excluded, resulting in water running, machine seal dry failure, cavitation automatic loading Valve, replace the machine seal.
