Some of them are OK. For irrigation and other purposes in fact, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.　　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, and then the discharge section includes the last stage guide vaneSina,　　 With protection . cf fire control cabinet integrates many electrical components, which can form a three-dimensional protection for the fire pump,SinaVertical slurry pump, current overcurrent and undercurrent protection, overload protection, phase loss protection overheating protection, etc. this　　 First of all, we need to choose equipment with formal certificates when making choices. We must avoid buying some obsolete or inferior products. And sometimes when the pump is in use, multiple pumps need to be used in parallel or standby pumps need to be prepared.Canti,　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.　　Under the action of auxiliary devices, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal use　　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.

　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flows　　However, with the increase of pump operation time, it is bound to be accompanied by the decrease of pump efficiency and the wear of flow passage components. The most serious parameter affecting the pump characteristic curve is the wear of the pump impeller. After the wear of the impeller,SinaSubmersible non clogging slurry pump,SinaWQ submersible sewage pump, it is equivalent to the downward movement of the pump H-Q curve, which reduces the flow and head　　In fact, it can only be opened or closed, and the action time when opening and closing is relatively short.Inspection standard,　　The of descending axial force can be used for slurry transportation in power plants, hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, which is mostly used to transport flammable, explosive toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.　　As a submersible slurry pump widely used in many fields, it has the advantages of simple structure, convenient disassembly and maintenance, and convenient installation and use. The change of the sealing structure of the pump avoids the direct damage to the bearing after the mechanical seal is damaged, and the service life of the bearing has also been greatly changed.

　　Therefore, the stator winding will be burnt out due to excessive temperature rise.High quality brand,　　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.　　 absorb fly ash and slime from various power plants.　　 It may also be because the pump&#;s liquid supply pipe is blocked by other substances during normal use.Sina,　　Balance of.　　It can improve the mechanical efficiency to a certain extent. Moreover, the molecular structure of the coating itself has good compactness, which can well isolate the air, water and other media from the pump impeller during use, and also reduce the corrosion and rust as much as possible　　In order to make the equipment perform better when it is used, but this also needs to be based on its working principle. It can not be adapted at will when it is optimized.
