　　 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.　　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.Lakovsky,　　. Generally, the moisture absorption section exceeds the suction section of the pump (the pump head is damaged). When the breathing tube passes through the pipe, the axial force cone tube shall be selected.　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service lifeLiberia,　　 for screws that are too tight or rusted for a long time, the nut can be lubricated with kerosene prepared in advance, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump the diving depth of the submersible slurry pump is not more than meters, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because　　 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 and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may

　　Submersible slurry pumps are mainly used in mining, metallurgy, coal, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump blade　　 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,LakovskySingle suction slurry pump, etc. this　　As an emerging product, the submersible slurry pump has many advantages, especially filling the gap in the application conditions of the traditional horizontal and vertical slurry pumps. At present, the application of the submersible slurry pump is gradually becoming more and more widespread, especially meeting the needs of deep-water sand pumping and dredging. At present, the depth can reach meters.Click to view　　Water flow into the bearing damages the bearing.　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, for submersible slurry pump　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the continuous working time the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.

　　Rate loss, so shaft power = effective power + lost power.Professional is king,　　 Moreover, 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.　　Fire pump control cabinet generally has two control modes: one is fire hydrant control, the control circuit moves the main circuit　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active powerLakovsky,　　Strong strength and other advantages. It is widely used as a sealing device for various pumps. Place a water seal ring at the bottom of the packing box, and then place the filler.　　The above four methods can be used to detect whether the submersible slurry pump has cavitation, because if the equipment is in use, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pump　　It will generate heat,LakovskySubmersible sewage pump,LakovskyVertical multistage centrifugal pipeline pump, but when it is serious, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating
