ProtarasAh slurry pumpCurrent situation of the industry

　　 bind the exposed copper wire to the cable core evenly, heat it with an electric iron, and infiltrate tin evenly.　　After meters, the sealing of the equipment can not bear the water pressure at this depth.Protaras,　　 wellbore integrity　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.Mechra Belqsiri, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops to　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged

　　The Tao part also consumes part of it.　　 Easy installation and maintenance. Small submersible sewage pumps can be installed freely. Large submersible sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is quite convenient for installation and maintenance.　　 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,ProtarasTwo stage 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. WhenPromotion,　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.　　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.　　Therefore, when the pump temperature is too high, you don&#;t need to panic. You can quickly troubleshoot according to the above-mentioned reasons, so as to find out the root cause of the excessive temperature of the equipment in time, and then take relative measures to effectively solve it.

　　 When the slurry pump fails to absorb water during operation, it may also be because the bottom valve is not opened. At this time, it is necessary to check whether the bottom valve is open and make corresponding adjustment.Supply chain quality management, 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)　　The following inspection shall be carried out: whether there are sundries between the impeller and the pump body due to too tight packing.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section,ProtarasVertical slurry pump,ProtarasSubmersible pump can pump sewage, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race,　　The whole packing body including the packing gland, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring packing ring and packing, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane　　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 the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.　　Many users, 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?
