Q: What are the important parameters of the pump?: The head is the unit weight of liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid used, referred to as meters.Speed nThe speed is the number of revolutions per unit time of the pump shaft. It is indicated by the symbol n. The unit is r/min.Cavitation allowance NPSHCavitation margin, also called net positive suction head, is the main parameter to indicate the cavitation performance. The cavitation margin has been expressed by delta H at homePower and efficiencyThe power of water pump usually refers to the input power, that is, the power transferred by the prime mover to the pump shaft, so it is also called shaft power. It is expressed by P;The effective power of the pump, also known as the output power, is expressed in Pe. It is the effective energy obtained by pumping the liquid out of the pump in unit time

Q: What does the pump mortar do?: Concrete pump before the need to transport water and pump pump material, dredge pipeline. In accordance with the technical specification for concrete pumping construction (JGJ/T10 - 1995), pumping concrete, pump mortar generally use cement slurry

Q: What does "anti pump" mean in pump operation?: The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)

Q: Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center: The line between the fire pump buttons should be NHBVR-4*1.5 lines. 2 start, 2 answer. Some manufacturers reported that the 3 lines can also, this need to see which is the specific equipment. In addition, we need to introduce 2 warning buses.The above lines are individually distributed

Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?: (4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.

Q: What is the difference between centrifugal pump and rotary vane pump? What are the distinctive characteristics or principles of rotary and centrifugal? O (a _ U) O thank you!: The vane pump can be divided into centrifugal pump, mixed flow pump and axial flow pump according to the direction of liquid flow in the impeller.Centrifugal pump is a kind of vane pump, which is the most widely used.

Q: Is the centrifugal pump large or small?: Centrifugal pump, the smaller the better the cavitation.1, centrifugal pump cavitation less, anti cavitation performance is better, the pump cavitation is called the necessary cavitation margin or pump inlet dynamic pressure drop, the smaller the better. Generally speaking, the pump cavitation is the need for cavitation, the pump inlet pipe said effective cavitation margin, that is, the device cavitation margin. For a given pump, at a given speed and flow rate required NPSH is called pump necessary NPSH, also called NPSH, is required to achieve the performance parameters of the pump cavitation, the internal flow and the centrifugal pump is composed of pump head itself, its physical meaning is that liquid drop in pump inlet pressure part degree, is to guarantee the pump cavitation does not occur, with surplus energy exceeds the vaporization pressure head at the inlet of the pump unit weight of liquid. The cavitation must be independent of the device parameters. It is only related to the parameters of the inlet of the pump. These parameters are determined by the geometric parameters at a given speed and flow.

Q: What are the conditions required for hydraulic pumps to complete oil absorption and compression?: There must be one or more sealing volumes, and the volume of work is variable;

Q: What is the cause of the damage of pump bearings?: First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.

Q: Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?: Calculate or refer to the water pump nameplate that the normal operating current, according to this data exchange switch.2) with 500V shaking table, measuring the cable, motor insulation is in line with the requirements
