Balance Balance institutions gimbal mechanism, balance sets, balance disc and balance piping and other components. 4. The main part of the bearing part of the bearing by bearing body and bearing components. This pump bearings have two sliding bearings and rolling bearings. Bearing not support axial forces, the pump in operation, the rotor section in the pump casing should be free to slide axially multistage pump performance, can not be sealed and the cooling of the rotor portion of the radial ball bearings in the pump suction, middle spit segments and vanes to combine top coat of molybdenum disulfide grease seal. Between the rotor portion and the fixed portion by a sealing ring, the guide vane sets, packing and other sealing. When the seal ring wear and guide vane sets has affected the work performance of the pump, it should be replaced. This type pump is in use, the position of packing rings to be placed correctly. How to repair the pump in the winter and maintenance 1, the pump is disabled, try to put the leftover water pumps and piping inside and outside the earth clean, to avoid freezing water after the pump and pipes freezing and bursting. 2, pump, foot valve, pipe and other iron castings, should brush the rust with a wire brush to clean multistage pumps, then be coated with rust colored paint and then be dried and then placed in the room or storage room ventilation dry place. 3, with belt drive, hang to dry after washing with warm water to remove the belt in a dry place away from direct sunlight, and do not be stored in a oil, corrosion, and cigarette smoke.

Available on the need to replace gasoline or kerosene to clean the bearing, butter, re-installed. 5. Check the pump impeller for cracks or holes, impeller retaining nut is loose, if any damage should be repaired or replaced. If the impeller wear too much or multistage pump broke fertile trustworthy, should generally be replaced with new impeller. Local damage can be welding, you can also use epoxy mortar repair impeller, impeller repair should be carried out after the general static balance test. Check the impeller wear ring at reducing the gap exceeds the specified value, should be repaired or replaced. 6, the shaft is bent or badly worn, it should be repaired or replaced multistage pump material, otherwise it will cause wear of the rotor unbalance and related components. 7. Remove the screws come soaked in diesel fuel with a wire brush to clean the inside and coated with oil or butter, reinstall it with plastic wrap or put away (can also be soaked in diesel saved), in order to avoid corrosion or missing.
