What is the assembly of mine submersible pump?

Mine submersible pump assembly in the use of the product specifications are described in detail. For the first time or each time, the assembly will need to be carried out in accordance with the instructions.
(1) preparation before assembly
1) read mine pump installation instructions and installation drawings and installation procedures for mine pump clear in mind.
2) prepare lifting equipment, measuring tools and tools.
3) to do a good job of cleaning up the installation site.
4) check whether the various components of mine submersible pump is missing
(2) inspection and assembly of the rotor of the mine submersible pump
The mine submersible pump rotor is composed of a plurality of components which are assembled on the pump shaft. Then, the locking nut is fixed on the relative position of the pump shaft. If the repair of the various parts can not meet the requirements, resulting in a larger radial pulsation, mine pumps in the operation of the process is easy to produce grinding, affecting the normal operation of the pump.
In the assembly, the rotor mine pump prior to the small installation, the impeller, shaft sleeve and balance disc are mounted on the shaft, the top point and then put 2 V iron or a micrometer, check.
(1) check each sleeve, sleeve and balance disc. Each rotation of the rotor dial gauge has a maximum value and minimum value. After several tests, the two values are recorded, the difference between the two is the degree of eccentricity.
(2) the same way to check the impeller mouth ring.
(3) the assembly of multi section mine submersible pump
After assembling the pump, the end face of the balance sheet must be checked. The tolerance of the pump body parts of the various parts of the manufacturing, repair accuracy, and assembly of the tension bolt before and after the degree of uniformity.
(4) the assembly of mine pump impeller inlet and outlet of the impeller is also very critical to the neutral. If the installation is not good will affect the performance of the pump. This can be measured in the final assembly, by checking the rotor. If the axial channeling momentum is larger, the balance disc and the balance sleeve can be mounted with a smooth surface and a uniform thickness.
