lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand, so as to move the sand pumping place back and forth for sand pumping, so that the sand pumping area in this area forms a honeycomb,PatriceSewage pump diving,　　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)Patrice,　　 Check and replace accessories regularly: check cables,PatriceVortex pump and pipeline pump, motor insulation and screws at least once a year. If it is damaged, it should be replaced in time.　　 Another possibility is that the gas is sucked in when the pump is in use.El-Sauce,　　What?　　When the water level reaches, the frequency of the frequency converter drops, and the slurry pump operates at a low speed. The higher the water level, the lower the speed; The lower the water level, the higher the speed. At the same time, the water level signal is transmitted to the control cabinet so that the operators can timely understand the liquid level. Through this control, the circulation in the slag slurry pool is basically unchanged　　In this way, when the equipment is used again, the solvent in the pump is often less,PatriceSubmersible sewage pump, and the power consumption is also less, and the efficiency of the pump in use is often improved, and the fact is

　　Promote the continuous expansion of the sales network group.　　 The pump fails to supply water or the flow is insufficient. The pump fails to supply water or the flow is insufficient. It is likely that the suction pipe has water leakage or the bottom valve has air leakage, but there are several possible reasons: the water inlet is blocked; The bottom valve is not deep enough underwater; The running speed of the water pump is not enough; leaf　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, but its water output is not very large when it is used so it is effective when it is used in many mountainous areasHow many?,　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, 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. When　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate, and transmits energy to the slurry medium to generate a certain flow rate, drive the solid flow, and realize the transportation of slurry.

　　 Another possibility is that the gas is sucked in when the pump is in use.Sincere service,　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.　　At present, all screw pump manufacturers regard dry operation protection as a necessary unit for equipment procurement.　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining stainless steel, titanium alloy and other materials used in China&#;s mining, short service life and many faultsPatrice,　　The other mechanical seal is a split seal, which can be replaced without disassembling the slurry pump.　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.
