How to maintain the shaft seal of Hebei slurry pump

At present, most shaft seals of slurry pumps adopt combined shaft seal structure, which can prolong the service life of bearing bodies. The traditional shaft seal structure of slurry pump is mostly sealed with asbestos packing, which is simple in structure but poor in sealing effect. Water leakage will cause serious wear of shaft sleeve and bearing, and packing and bearing will be replaced frequently. After research, the slurry pump adopts double-end mechanical seal and auxiliary impeller combination seal, and the seal quality has been fundamentally improved. There is no leakage of shaft seal, no wear of shaft sleeve, no need to replace packing, and no high-pressure shaft seal when the pump is running. Water, so as to solve the problem of slurry pump shaft seal leakage which has long plagued production. After long-term use, it is necessary to carry out some maintenance on the shaft seal. Specific maintenance contents are as follows: Regularly check the water pressure and water volume of shaft seal. The combined seal of auxiliary impeller and packing requires that a certain amount of clear water always flows along the shaft, the tightness of packing gland is adjusted regularly, and the packing is replaced regularly; For mechanical seals, ensure that the supply pressure and quantity of high-pressure shaft seal water and shaft seal water meet the requirements. Regular maintenance can prolong its service life. Hebei Yingdike Pump Industry Group Co., Ltd. is a professional manufacturer of slurry pumps, submersible slurry pumps and sand suction pumps.
