　　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, and the market recognition is continuously improving, especially meeting the needs of deep-water sand pumping and dredging. At present, the depth can reach meters.　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland,Schoenberg BerlinUsed pipeline pump, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.Schoenberg Berlin,　　Secondly, let&#;s talk about the difference between WQ and QW sewage pumps.　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve, it means that the pump is fullDundock,　　Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demand　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.　　After a certain value, which is called the vaporization pressure of water at this temperature.

　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact,Schoenberg BerlinCorrosive pipeline pump, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family, when we use it, the flow is small　　In order to facilitate the disassembly of the impeller, during the design of the slurry pump, the impeller is connected with the pump shaft through reverse buckle. This is why the impeller will be turned off when installing a new slurry pump. Therefore, we must pay attention to the impeller marked on the pump body during preliminary installation and use　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use, when the load conditions do not match the model of the slurry pump, for example, the pump lift used is too high or too low, which will lead to overload, so we are selecting the pumpWelcome to inquire,Schoenberg BerlinBaigang deep well pump,　　 strip the outer layer of the cable to expose the copper wire for to mm, gradually thin the rubber near the wire core, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), and dry it naturally.　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water　　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.

　　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 powerAdministration,　　It is occasionally found that there is insufficient liquid supply when using so what are the reasons for this situation and how to deal with it.　　The specific treatment methods are as follows: first, check the power supply of the power supply to see whether the connector of the power supply is secure, whether the switch is tight, and whether the fuse is intact. In case of short circuit, short circuit, fuse burnout and other problems, it shall be repaired in time. If it is not a power problem, check the water pump　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.Schoenberg Berlin,　　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, in fact the fixing nut on the shaft shall be　　Only in this way can its service life be extended to a large extent.　　Some of them are OK. For irrigation and other purposes, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.
