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.

Dear Hello Deep well submersible pump motor maintenance is as follows; 1.Since the working environment of the submersible pump is in the water, the waterproof measures must be done; Generally, the submersible pump will come with a few meters of cable with pants, the remaining distance to buy a cable to connect, when connecting the cable, we must ensure that the line and the line are well dissolved, and the connection is firm, and then use the electrical tape with the waterproof tape tightly wound, do not only use the waterproof tape or only the electrical tape about the winding, because the humidity in the well is very large, to ensure that the water vapor can not enter the inside of the cable, otherwise there will be a phenomenon of burning out the motor 2The pump should be filled with water before installation, which is also a point that must be paid attention to, some customers may think that the submersible pump is placed in the water to work, and it doesn't matter whether to add water or not.

In fact, this statement is very wrong, we add water is added to the inner cavity of the motor, because the motor is running at 2900 rpm per minute, high-speed operation will cause the motor to heat up, and the water just plays a role in cooling, if no water is added, the life of the motor will be greatly reduced, and it is easy to burn out. 3.If the water quality in the area where the pump works is not very good, it is recommended to use galvanized steel pipes, if there are conditions, stainless steel pipes can also be used, and ordinary iron pipes are not recommended to be used, because the pipeline is soaked in water for a long time, and ordinary iron pipes are prone to rust and leakage after a long time of soaking.

4.When the pipe is connected, check whether there is debris between the gasket and the flange, whether the docking certificate, and ensure the tightness between the pipeline when fastening with screws, if the connection is not tight, there will be water leakage when put in, and it has to be hoisted out again for maintenance, causing unnecessary trouble, so it is best to check it more when connecting to ensure that nothing goes wrong. 5.

After the installation is completed, be sure to test the water to judge whether the pump is positive and negative, if it is reversed, you need to adjust the corresponding phase line, observe it for a while after completion, if there is no other situation, do a good job of waterproofing outside the well, to prevent water from flowing into the well around the well, affecting the use of the pump.

Note: 1. Drain the liquid in the pump casing;

2. If the bearing parts are lubricated with thin oil, the lubricating oil should be discharged;

3. Remove the auxiliary pipelines that hinder the disassembly, such as balance pipes, water seal pipes and other pipelines and leads;

4. After removing the last impeller and the key, remove the middle section (including the guide vane): continue to remove the impeller, the middle section and the guide vane of the remaining stages of Gao's according to the same method, until the first stage impeller is removed;

5. After unscrewing the connecting nut between the suction section and the bearing body and the bolt on the bearing press-through, remove the bearing parts (Sanchang Pump reminds that the pump coupling should be removed before this);

5. Extract the shaft from the suction section, unscrew the fixing nut on the shaft, and remove the bearing inner ring, O-shaped sealing ring, shaft sleeve and backup sleeve in turn.

So far, the disassembly work is basically completed, but in the above-mentioned disassembly process, there are still some parts that are connected to each other when they are connected together, and under normal circumstances, Qi leaks and screws the connecting bolts or nuts under the reeds can be removed.

Summary. 1.Untie the cable tether, remove the tubing part, and remove the wire guard.

2.Unscrew the drain bolt and drain the water in the motor cavity.

3.Unscrew the water filter and loosen the fixing screws on the coupling that hold the motor shaft in place.

4.Unscrew the bolts connected to the motor at the water inlet section to separate the pump and the motor (pay attention to flatten the unit when separating to prevent the pump shaft from being bent).

5.The disassembly sequence of the pump is: water inlet section, impeller, diversion shell, and impeller. Check valve body, use a special tool to loosen the conical sleeve that fixes the impeller when removing the impeller, and avoid bending the pump shaft and bending the parts during the disassembly process.

How can I pull the deep well pump motor out of the housing?

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

1.Untie the cable tether, remove the lead code of the pipe part, and remove the wire guard. 2.

Unscrew the drain bolt and drain the water in the motor cavity. 3.Unscrew the water filter and loosen the fixing screws on the coupling that hold the motor shaft in place.

4.Unscrew the bolts connected to the motor at the water inlet section to separate the pump and the motor (pay attention to flatten the unit when separating to prevent the pump shaft from being bent). 5.

Check valve body, use a special tool to loosen the conical sleeve that fixes the impeller when removing the impeller, and avoid bending the pump shaft and bending the parts during the disassembly process.

Laugh and do it. The motor is insulated, afraid of short circuit caused by water, there are fixing screws and sealing rings in the shell of the pump, after removing the skin and holding the fixed screws of the stool, the jujube buried impeller of the pump is suitable for the motor shaft to be connected, and then the demodulation motor of Sumiyoshi is separated from the pump body, and it can be removed.

The submersible pump of the deep well is broken and stuck a few meters up, how can I get the submersible pump up.

About your question: the deep well submersible pump is broken and a few meters up to get stuck, how can you get the submersible pump up here to help you inquire: 1. Use a steel bar with a diameter of more than 20 mm about 2 meters long, and the top is dislocated and welded a few barbs, one end is tied with a thick nylon rope, continue to go down, and after the hook is hooked, the rope is tied to the chain block at one end and dragged on.

If there is a lot of silt in the well, you can wash the well (blow the sand) before the pumping. Of course, if the pump is relatively large, increase the diameter of the rebar rod and nylon rope appropriately. 2. There are two reasons why the deep well water pump is stuck:

First, it is the stone face and the slag of the well wall when the well is drilled, and after a year of precipitation, the water pump is buried, and it may be buried in the strainer part, and the water is not available. Second, the falling object of the well wall is stuck, you pull it, see if the pump does not move, it must be the sediment buried in the pump, so you have to use something to pull up, pull it well, the falling object is stuck, the water pump can move, you pull the pump back and forth, and break the falling object, generally it is a vulgar stone stubble, not a stone, the stone is not broken, and generally does not fall down, so that you can pull the water pump up. Hope it helps you <>

There are other questions you can continue to consult, thank you for your trust, the above is my reply to the opening of Qinqin, I hope it can help you, I wish you a happy life If the content is helpful to you, I hope you can get your likes, thank you very much!

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.
