Disassembly and Usage of Deep Well Pump Working

Disassembly and Usage of Deep Well Pump Working
Put part of the work flat on the board, first remove the filter pipe. Single-stage centrifugal pump, the upper and lower diversion shells to be imprinted each section marks, note the sequence number, to prevent the installation of the wrong. Remove the fixing screws between the two water pumps. From the above order down demolition. First remove the deflector shell, the demolition of the use of special tools or pipe clamp stuck, the shell screwed down (positive thread). Leakage of the impeller, impeller impeller cone sleeve washed down, remove the impeller and then conical cones opened with a screwdriver, the tapered sleeve removed.
In the above-mentioned method of a guided shell removed, dismantling to the lowest impeller temporarily not to remove the impeller, the lower deflector shell after unscrewing the impeller position in the shaft for a mark and then removed, So as not to affect the location of the entire installation of the shaft position and clearance adjustment.
In order to ensure the normal work of the drive shaft, shaft to extend its service life, should be noted in use:
1. It is strictly forbidden to start high-speed gears for automobiles.
2. Climb the clutch pedal.
3. It is strictly forbidden to overload the vehicle and speed up the vehicle.
4. The working condition of the drive shaft should always be checked.
5. Should always check the drive shaft hanger fastening, whether the damage to the bearing rubber, shaft connection parts are loose, whether the transmission shaft deformation.
6. In order to ensure the dynamic balance of the drive shaft, should always pay attention to whether the balance of solder-off. New drive shaft assembly is provided in the new drive shaft loading should pay attention to the extension of the assembly of the tag should ensure that the flange fork in a plane. In the maintenance of demolition drive shaft should be in the telescopic sleeve and flange axis printing assembly mark, for re-assembly to maintain the original assembly relationship.
7. Should always be universal joint cross bearing grease, the summer should be injected into the No. 3 lithium-based grease, the winter injection of No. 2 lithium-based grease.
When the case of the pump body induced corrosion is not open, the application of hand hammer beating around the pump, while beating.
Leakage of the impeller, impeller impeller cone sleeve washed down, remove the impeller and then conical cones opened with a screwdriver, the tapered sleeve removed.
In the above-mentioned method of a guided shell removed, dismantling to the lowest impeller temporarily not to remove the impeller, the lower deflector shell after unscrewing the impeller position in the shaft for a mark and then removed, So as not to affect the location of the entire installation of the shaft position and clearance adjustment.
When the case of deep cavitation pumping body is not open, the application of hand hammer beating around the pump body, while beating with a large pipe clamp on the pump to the left-hand screw, generally can be opened
