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)　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift, the cut impeller is usually used. The cut isvitality,　　 Take out the locking ring of the coupling, unscrew the fixing screw and remove the connecting bolt to separate the motor and water pump.　　When using the sand pump be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation,vitalitySingle suction slurry pump,vitalityVertical centrifugal slurry pump, be careful not to exceed the bearing on the pump support to avoidPatzun,　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed　　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.　　For example,vitalitySewage pump diving, it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?

　　 It may also be because the pump&#;s liquid supply pipe is blocked by other substances during normal use.　　In fact, as far as whether the vertical pipeline pump has a suction lift is concerned, we can tell that it has a suction lift. But what you need to know is that suction range and self-priming are actually two different concepts.　　Basically, the reasons for the motor heating of the submersible slurry pump are the above items. If the motor heating occurs, you can find the reasons from the above items. However, people who do not know electricity should not repair it by themselves, so as to avoid peopleInstallation materials,　　What?　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.　　Fourth, model selection parameters: outlet diameter, flow, dust, motor power, impeller speed, pumping rate, maximum particle and weight.

　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.index, so that the product can operate safely for a long time under adverse working conditions.vitality the motor can add a variety of protection devices such as water inflow detection and overheating,　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome and the application occasions are subject to many restrictions.　　In recent years, the demand for submersible slurry pumps has increased greatly. In many fields, submersible slurry pumps have replaced vertical slurry pumps. What are the differences between the two? Let&#;s yze.　　Start the priming pump. Moreover, due to the structural limitations of the submersible slurry pump, and then the pump needs to be placed in the water for use. Therefore, the submersible slurry pump must be
