Submersible pump assembly process

Submersible pump assembly process
      300JC / K210-10.5x5 submersible pump assembly site must be clean and tidy, to be equipped with parts of the surface is not allowed to have sediment, dust, all bolts should be symmetrical tight; according to decomposition of the mark, the following order of assembly of the pump Body: Insert the two ends of the impeller shaft into the bearing hole of the lower shell and the upper shell respectively. One end of the short thread on the impeller shaft is used for fixing the nut when assembling. It should be pierced into one end of the lower shell, Note that the location of the two ends of the threaded length of the assembly can not be wrong, the size should be consistent with the drawings. The gasket and the installation nut screw into the impeller shaft under the shell side, remove the upper shell, in the lower shell set into the chain clamp, the next should be placed square wood, the other end of the impeller shaft is also flat with objects to ensure the axis line flat straight. Set into the impeller and the taper sleeve, the impeller shell conical surface consistent with each other, and then hit the cone with a punch sleeve. Wash the contact surface of the two shells, sets into the sets, the first hand-screwed, and in the thread with the Department of dilution painted thick white paint. Then, use the chain clamp to tighten the two shells. So that the same steps can be installed to the last impeller. (6-10 mm), if the requirements can continue to install the upper shell, if the amount of string is less than 4 mm (or less than 4 mm) , Should find out why reinstall. With the chain clamp to tighten the upper shell, and then measure a size, should meet the requirements of the drawings, the pump allows ± 3 mm installation error. In the assembly, the drive shaft and the coupling thread should be coated with a layer of Vaseline or molybdenum disulfide, to prevent rust death, bearing bracket on the mouth and the pipe should be coated with a layer of thin layer of butter to prevent rust. According to the opposite order when the demolition, from bottom to top in order to install the pump body, water pipes, drive shaft, bearing bracket, pump and motor.
