Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)　　 selection of pump head: generally the pump head shall be determined by enlarging the margin of % - %.Tokyo,　　During normal operation, the impeller of the slurry pump becomes tighter and tighter as it turns. The more it is used, the easier it will operate. However, if the slurry pump reverses, it will directly cause the impeller of the slurry pump to fall off. The slurry pump must be disassembled and then re inspected, installed and tested.　　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.Buchanan,　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, and the income has been increased.　　 Another possibility is that the gas is sucked in when the pump is in use.　　It, generator and market formed at the beginning of construction have gradually formed a certain scale after more than ten years of rapid development. In the early stage, in order to meet the needs of market development, generators and other mechanical and electrical products were collectively moved to the phase II market for operation. With a good business environment, water pumps and generators

　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.　　The answer to this question must be! Submersible sewage pump has attracted more and more attention because of its wide range of applications and strong sewage treatment capacity, but improper use and maintenance will lead to submersible sewage.　　Compared with the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump such as sand pumping on board, prospecting, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pumpQuality inspection report,　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.　　Potential is convenient and flexible. It is easy to operate. It can be operated by a fool who turns on the power supply under immersion; It has a wide range of applications. In many cases, because it does not need too many auxiliary facilities.　　 strip the outer layer of the cable to expose the copper wire for to mm which can be brought wherever it is needed, 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), wrap the insulation layer and sheath layer, and dry it naturally.

　　In this way, when the equipment is used again, the solvent in the pump is often less, and the power consumption is also less, and the efficiency of the pump in use is often improved, and the fact isassets,TokyoWater well pipeline 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.　　Its working principle is as follows: when the screw pump is working, the liquid is sucked into the sealing cavity formed by the rotor and stator. Due to the rotation of the rotor, the liquid follows the sealing cavity to move along the axial direction from the suction side to the discharge side of the pump, and the continuous suction and discharge realize the liquid transmission .　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve,TokyoSubmersible non clogging slurry pump, adopt the water level closed-loop control mode,TokyoVertical heavy-duty slurry pump, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. WhenTokyo,　　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 pump　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, wide flow passage, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. Suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.
