How to disassemble the submersible pump How to disassemble the pumping pump

Something stuck is a reason, and it may be that the three-phase electricity is connected to the two phases, this has to be checked with a multimeter, go to find someone to borrow a multimeter, and measure whether the three wires of the submersible pump are broken. It is possible that the impeller is stuck and the friction of the stator rotor does not rotate. See if the sand has infiltrated into the bearing, clean it up, turn the impeller by hand, and see if it is smooth to rotate.

The pump has different specifications and different dismantling procedures, so it's not easy to answer.

Summary. 1. First of all, we must see the model of our pump clearly when dismantling, and the disassembly method of each model is different.

2. Under normal circumstances, the water pump is to remove the power cord first, we can see that the pump has a back cover, open the back cover, you will find that there are a lot of power cords inside, first remove the power cord one by one.

3. After removing the power cord, we can remove the back cover, after the back cover and the power cord are removed, we will then remove the front end, after removing the front end, we will check whether there are any screws around, if so, we must prepare a screwdriver to remove all the screws.

4. After that, we dismantle the core of the water pump inside, that is, the rotor of the water pump. After the water pump core is taken out, we can clean it with some cleaning tools, and the disassembly of this water pump is more detailed and needs to be carried out step by step.

5. There is a very simple way to disassemble the pump, which is to find an iron wire through the two holes of the pump, lift it and knock on the edge, at this time the pump shaft and pump core between the pump and the front end and back cover will all be loose, in this loose state we take out the rotor, front cover and back cover and other parts of the pump, right or wrong.

Dear, if it is useful to you, please give it a thumbs up, and I wish you a happy life and smooth work. Thank you.

Dear, hello: disassembly method of deep well submersible pump; Before disassembling the deep well submersible pump, attention should be paid to draining the liquid in the pump body. If the bearing parts are thin lubricating oil, the lubricating oil should be cleaned, and the auxiliary pipelines that hinder the disassembly and assembly, such as equalizing pipes, water seal pipes and other pipes and wires, should be removed in advance.

The disassembly and assembly process of the pump needs to start with the bearing components on the fork tooth side. Due to the different construction of the pump, it may be slightly different when disassembling and assembling. The above steps are the steps for disassembly and assembly:

1.Loosen the anchor bolt on the screw cover of the discharge side bearing and the connecting nut between the discharge section, stuffing box and bearing, and remove the bearing; 2.Loosen the round nut on the shaft, remove the bearing bore, the bearing swivel cover and the stopper, and then remove the packing body; 3.

Remove the O-ring, coupling, balance plate, key on the shaft, and then remove the discharge section (including the final guide vane, balance ring, etc.). 4.After removing the last impeller and key, remove the intermediate area (including the guide vane):

In the same way, remove the other centrifugal impellers, the middle area and the guide vane until the skull centrifugal impeller is removed; 5.After unscrewing the connecting nut between the moisture-absorbing section and the bearing and the bearing press-in bolt, remove the bearing component; 6.Pull the shaft out of the suction section, unscrew the fixing nut on the shaft, and remove the bearing bore, O-ring, coupling and retaining sleeve sequentially.

In these processes, some parts are connected to each other and can be removed after twisting the connecting anchor bolts or nuts under normal circumstances. Thank you for your trust, the above is my reply, I hope it can help you, and I wish you a happy life.

Summary. Disassembly of deep well submersible pump: dismantling of deep well submersible pump first remove the connecting bolt outside the pump base and the foundation, use the three-legged pulling rod erected on site, use the manual hoist to slowly lift the pump base together with the downhole part to set the height, clamp the final lifting pipe with the clamping plate, and hang the wire rope on the clamping plate, so that the lifting part is transferred from the pump seat to the clamping plate.

At this point, the pump base can be removed. The downhole part is slowly lifted to a fixed height, and the lower water lifting pipe is clamped with another clamping plate, so that the lifting part is transferred to the lower water lifting pipe At this time, the water lifting pipe can be removed. If the lifting position is changed in this way, the deep well pump can be completely dismantled

When removing the impeller, use the casing against the small head end face of the tapered sleeve, hammer the other end of the casing, and the impeller and the tapered sleeve can be separated.

The disassembly method of the submersible pump is as follows:

1. For general centrifugal pumps, the general disassembly sequence is as follows: drain the lubricating oil and residual water, connect with the pump body, disassemble the connection between the pump body and the power machine, remove the anchor bolts, dismantle the vacuum pump, cover and related accessories, remove the cover plate, packing gland, remove the impeller and coupling, and extract the shaft assembly; Then it is disassembled into parts according to different component structures.

2. For connections that cannot be disassembled or will reduce the quality and damage the connecting parts after disassembly, it is necessary to avoid disassembly as much as possible, such as sealed connection and interference connection. The screw connection is removable, but due to the age, the screw rust cannot be unscrewed, and it must be soaked with kerosene for several hours before being screwed; If it still can't be loosened, you can use saws, gas cuts and other square sail hall calendars to remove the screws, but to avoid ambushing Li to avoid injury to the body.

3. When disassembling, the force should be appropriate, especially to protect the main structural parts from damage. Under the condition that a part has to be dismantled, it is necessary to preserve the parts with higher value, difficult manufacturing and procurement, and better quality.

4. Finally, use a hammer to gently knock out the shaft, so that the rotor of the pump motor is removed. It provides convenience for the maintenance of the water pump stator.

Summary. If the safety is guaranteed, the structural disassembly steps of the submersible pump are as follows:1

Disconnect the power supply, turn off the motor, and disassemble it after the motor cools down. 2.Remove the connection part of the submersible pump pipe, remove the connection plate and cable joint.

3.Open the wire rope interface on the submersible pump. 4.

Lift the submersible pump out of the water (one person in the general crane organization is responsible for holding the lifting rope and dismantling it). 5.Disassemble the submersible pump protective cover, fish mouth, strainer, etc.

6.Remove the modifier and K-shaped or U-shaped groove on the submersible pump body, and remove the bearing parts if the water seal needs to be replaced. 7.

Disassemble the housing, bearings and impeller, and if adjustment or replacement is required, check the wear of the parts and the surface of the impeller for floating pads, scratches or grooves. If so, grinding corrections or replacement parts are required. 8.

Remove the cover plate of the motor, remove the stator, rotor, bearing seat and cable joint, and check whether there is any damage or aging of the cable. 9.Remove components such as cast iron, adapter shaft and connecting plate of the submersible pump.

10.Disassemble maintenance parts such as water seals and oil seals. 11.
