the noise method directly detects the noise of the equipment in the detection process

　　 in addition,ChachuvapaVertical heavy-duty slurry pump, but such measurement will also be affected by the surrounding noise, so in fact, such measurement is not very accurate.　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer, caliper, feeler gauge, square ruler, copper bar, screwdriver with handle, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn, etc.Chachuvapa,　　Is the submersible sewage pump a submersible pump or a sewage pump QW (WQ) submersible non clogging sewage pump QW (WQ) submersible non clogging sewage pump: the pump adopts a unique single or double blade impeller structure, which greatly improves the sewage passing capacity and can effectively pass through times the fiber material and diameter of the pump diameter　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.Vilyeyka,ChachuvapaSubmersible pump can pump sewage,　　There are many types of submersible slurry pumps available in the market, and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected its application effect will be great　　 Inspection before installation: Check the specification, size and quality of thick and thin accessories.　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, so it is effective when it is used in many mountainous areas

　　After understanding the working principle of the submersible slurry pump we will also know that those parts are prone to wear during normal use. In this way, we can carry out targeted anti-corrosion and wear-resistant treatment on these parts during optimization, so as to improve the integrity of the equipment and　　The inner wall is corroded and the outside air is sucked in. The pipeline pump packing is worn or the packing is not compacted.　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.Sales Department,　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local places　　The balance ring is also disassembled; Then remove the last stage impeller and the key back, remove the impellers,ChachuvapaPipeline pump body, middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.

　　The above is the reason for the insufficient liquid supply of the water pump when it is in use,　　 one method is to use ultrasonic method to detect whether the equipment has cavitation. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps tend to have better measurement results when in use.　　The treatment method is as follows: first, check the circuit voltage to reduce the speed of the water pump.　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, the outlet sluice valve shall be closed, and water shall be injected into the pump to ensure that the pump is full of water without air.Chachuvapa,　　 If it is found that the impeller is damaged and the liquid supply is insufficient, it is necessary to replace the new impeller in time for use.　　 Then unscrew the nut at the front end of the pump shaft, remove the cover plate, and press out the middle impeller and water seal.　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.
