When the deep well pump is decommissioned for a long period of time, it should be started for 20~30 minutes per week to prevent the electric motor and electrical equipment from being rusted by dampness or the rotating part of the pump, and then rubbing the oil against the pound. If the outage period is in winter, antifreeze measures should be taken.
If the horizontal multi-stage centrifugal pump is operating normally, it can generally be repaired once in two years, but the overhaul period should not exceed 3 years at most. During each irrigation period (2500 hours), an overhaul protection was performed to replace worn consumables.
Electric pump lifting and handling:
1) Disconnect the cable and disconnect it from the power supply.
2) Use the installation tool to gradually dismantle the outlet pipe, gate valve, and elbow pipe, and use the pinch pipe plate to press the next section of the water pipe. In this way, disassemble the pump one by one and remove it from the well. (In the process of lifting and unloading, it is found that there is jamming and it cannot be forced to lift. It should be lifted up and down and left and right to activate the customer service card point for safety.)
3) Remove the shield plate, strainer, and cut the cable from the leads and the three-core cable or flat cable connector.
4) Take out the lock ring on the coupling, remove the fixing screw, and remove the connecting bolt to separate the motor and the water pump.
5) Release the water in the motor.
6) Dismantling the water pump: Disassemble the wrench and remove the water inlet section by left-hand rotation. Use the disassembly cylinder to impact the tapered sleeve on the lower part of the pump. After the impeller is loosened, remove the impeller, conical jacket, and remove the guide shell. , diversion shell, upper diversion shell, check valve, etc.
7) Motor dismantling: Remove the base, thrust bearing, thrust plate, lower bearing housing connecting seat, water thrower, remove the rotor, remove the upper bearing housing, stator and so on.
Electric pump assembly:
(1) Assembly sequence of the motor: stator assembly → assembly of the lower guide bearing → assembly of the rotor → thrust plate → left nut → thrust bearing assembly → base assembly → assembly of the upper guide bearing housing → skeleton oil seal → connection seat. Adjust the studs so that the motor shaft extension meets the specified requirements. Then adjust the pressure regulator, pressure regulator and cover.
(2) Boiler feed pump assembly: Fix the shaft and water inlet section to the seat where I can install the impeller and taper sleeve on the shaft, and then install the guide shell and impeller to install the shaft. Upper case, check valve, etc.
In the assembly of the motor water pump department of the eighth grade or less, first tighten the nut evenly between the inlet section and the contact plane on the bearing seat, and install the coupling, the pump shaft, the fixing stud, and the lock ring. The barrel and impeller sleeves are fixed on the pump shaft, and the guide shell and the impeller are installed so that the upper guide shell and the like are sequentially installed. After the pump is installed, pull the pull nut, remove the gasket, tighten the puller nut, and then turn the electric pump from the coupling. The rotation must be uniform.
Deep Well Pump Maintenance and Disassembly and Assembly Points for Attention
Deep-well pumps with calcium-based grease bearings should be changed once every six months. When changing oil, clean the bearings with kerosene or diesel oil, wash them, and add new grease. For each half year of operation of the motor bearing, the oil drain plug shall be screwed off, and the waste oil shall be discharged and then poured into the new oil.
