Griff á DaUsed pipeline pumpWhat characteristics should be paid attention to

　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary times　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should chooseGriff á Da,　　 Packing shaft seal: the packing shaft seal is the most common seal, with simple structure,Griff á DaIrrigation deep well pump, convenient maintenance and low price. However, the shaft seal water must be used. For the working conditions that are not suitable for the auxiliary impeller shaft seal, the packing shaft seal can be used.　　The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role inAngelholm,　　Some impurities will entangle the impeller, so generally, the open impeller will be used, so there is no need to worry about getting stuck in the process of transporting sewage.　　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,Griff á DaRubber lining submerged slurry pump, and then the discharge section includes the last stage guide vane　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used, so that they can have good wear and corrosion resistance when they are used, and can be used to transport most of the media when they are used. Phreatic slurry

　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by η Indicates.　　Domestic stainless steel pipeline pump products have greatly improved their technical level through introduction, absorption,Griff á DaCorrosive pipeline pump, renovation, digestion and innovation. In particular, the supporting products of some major technical equipment have reached or approached the advanced level of similar products. With the continuous expansion of the market, stainless steel pipeline pump　　The effective power is also called output power, which is expressed by PE. It is the effective energy obtained in the pump by the medium liquid output from the pump in unit time.Where can I find it?　　Water pump is a kind of machinery that pumps energy liquid. It is a machine that converts the mechanical energy of the prime mover into the potential energy of the pumped liquid. Driven by power machinery, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.　　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.

　　The water pump is not only the water supply for the city, but also the household water purifier used in our home. There is a with pump equipment to help us purify water. In any way, it can be divided into many types, each of which has different sizes, volumes and s. Therefore, many people believe thatproduction costs　　 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.　　 number of lifting pipes　　 The fixing method of the impeller is changed from screw thread to key clamp to prevent the impeller from falling off and causing damage!Griff á Da,　　After meters, the sealing of the equipment can not bear the water pressure at this depth.　　In order to make the equipment perform better when it is used, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?
