The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane　　 in addition, the noise method directly detects the noise of the equipment in the detection process but such measurement will also be affected by the surrounding noise, so in fact, such measurement is not very accurate.Slema,　　Environmental conditions for normal operation of ordinary YLB motor:　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, tighten the adjusting screw of the bearing box evenly and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mmJustad,　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.　　In addition, the sundries inside the pump body and impeller shall be cleaned. Then calibrate the pump shaft and motor shaft of the slurry pump to make them on the same horizontal line.　　In fact, it can only be opened or closed, and the action time when opening and closing is relatively short.

　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops to　　 With protection . cf fire control cabinet integrates many electrical components, which can form a three-dimensional protection for the fire pump, including voltage overvoltage and undervoltage protection, current overcurrent and undercurrent protection, overload protection, phase loss protection,SlemaWater well pipeline pump, overheating protection, etc. this　　The premise of using this method is that the water gun must have sufficient flow during use,　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media,SlemaVertical centrifugal slurry pump, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore,　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.　　The lift of deep well pump is calculated according to the following formula　　Wheel, which are wear-resistant, corrosion-resistant, non clogging, and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower.Slema,　　 Moreover,SlemaSingle suction slurry pump, the processes of these two pumps are also different, and the sewage pump can generally be adjusted. Submersible pumps are generally used in some special or other places.　　The two have certain commonalities. They are both submersible. As the name suggests, the pump is in an invasive state when running. The submersible slurry pump is a kind of submersible pump, but generally speaking, people often say that the submersible pump refers to the clean water pump such as the submersible pump for domestic water and farmland irrigation and pumping　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding, the tape shall be stretched twice and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.
