　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.Graz,　　 The pump without self circulation cooling device shall not be exposed to the water surface for a long time to prevent the electric pump from overheating and damage.　　Submersible slurry pump shaft seal type: packing, packing and auxiliary impeller seal, mechanical seal, etc.Bonao,　　When in use, it can drive the impeller to rotate so as to drive it to flow.　　Work, no noise and vibration, and the site is cleaner.　　Stability and reliability of seals between pump bodies.

　　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.　　The discharge side of the pump must be equipped with a valve (ball valve or stop valve, etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer　　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 vaneStandard requirements,　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, 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　　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, in which the constant active power

　　 Next it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious, and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However you can place abrasive cloth on the glass or dry wood, if the thrust rubber water seal is used, whenThe cheapest,　　 When starting the slurry pump,GrazCarbon steel explosion-proof pipeline pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　I believe you have such a question when using the submersible sewage pump, that is, is this pump a submersible pump? Or is it a sewage pump? In fact, this question is very easy to distinguish. You can take a look at the following contents sorted out by Shanghai Shenquan.　　However,GrazSmall deep well pump, there is also a disadvantage of using the auxiliary impeller sealing system, that is, it takes some energy on the auxiliary impeller of the submersible slurry pump, which is generally about %. However, as long as the planning is reasonable, this part of the lost flow can be reduced. The slurry pump is mainly applicable to electric power, metallurgy and coalGraz,　　Commodity.　　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.　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.
