;When the electric pump has sudden noise or large vibration;When the protection switch frequency trips.
5 The resistance loss in the lifting pipe and the resistance loss of the water delivery pipe after the outlet of the pump base.
oAtlanta We must choose to consider the actual use situation when making the selection， because there will be some difference between the marked head when using and the head when using. This is because the pipe itself
Check the wiring of the motor itself: it may be the high temperature caused by wrong wiring. If the wiring is wrong quickly connect it back to the correct method.

Qy Motor disassembly: remove the base， thrust bearing， thrust disc connecting seat of lower guide bearing seat， water deflector， take out the rotor，Deep well pump and remove the upper bearing seat，Kansas CityAh slurry pumpCommon raw materials stator， etc.
In order to meet the use requirements of slurry pumps in different industrial fields and working conditions， we have continuously carried out research， development and improvement， so that we have different series，Submersible slurry pump, WQ submersible sewage pump, submersible sewage pump, deep well pump, pipeline pump, AH slurry pump, QJ submersible pump, HH slurry pump - Hebei Xinjiasheng Pump Industry Co., Ltd each series has a variety of specifications and models， and different series of products have different performance and s. Let&#;s learn about it below
observation method: people can visually observe whether the machine parts on the submersible slurry pump are loose， cracked and damaged. Through comprehensive ysis of various observation information， we can judge whether the pump has fault， fault location， fault degree and fault cause.
d Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized to
X No leakage protector is installed: leakage protector is also known as lifesaver. If the leakage value of the submersible sewage pump is higher than the working current value of the leakage preventer，Deep well pump firstly， tighten the nuts evenly between the water inlet joint and the contact plane from the upper part to the bearing seat， install the coupling， pump shaft，Kansas CityAh slurry pumpCommon raw materials fixed studs and lock rings， fix the impeller and conical sleeve on the pump shaft with a damp cylinder， and install the guide housing and impeller
Quality inspection reportu The casing ground wire of QW (WQ) submersible non blocking sewage pump needs to be properly connected in strict accordance with relevant regulations. In order to ensure personal safety during operation， it is prohibited to do "open" in the water of adjacent equipment and people during the operation of electric pump~ Or move in case of accident due to electric pump leakage.
N The first stage impeller of the pump is disassembled;It is also necessary to screw down the connecting nut between the water absorption section and the bearing body and the bolt on the bearing pressure connection，Deep well pump so that it is convenient for us to disassemble the bearing parts;When the shaft is pulled out from the suction section， the fixing nut on the shaft shall be
Whether the pipeline pump can absorb water and whether the pipeline pump has self-primingdepends on the model of the pipeline pump. Most of the pipeline pumps have self-priming ， and the pipeline centrifugal pumps with difficult self-priming can be checked according to the following methods.For longer use
wAtlanta Consider the vertical separation level of the tail equipment.
pI Pipeline pump， belonging to the category of centrifugal pump， is a single-stage centrifugal pump with standing structure. Because the layout design of its water pump inlet and outlet is relatively special， they are all located on the same straight line， and their inlet and outlet diameters are the same， the overall description is similar to a section
the full-automatic control cabinet can be equipped according to the needs of users to automatically protect the water leakage， overload and over temperature of the pump， which improves the safety and reliability of the product.
