Seen the water pump, all know what is a water pump. The pump is conveying liquid or causes the liquid turbo-charged machinery. It transmits the mechanical energy or other external energy transmitted to the liquid, causes the liquid energy increase, mainly used for conveying liquid, including water, oil, the sour lye, the emulsion, hangs the emulsion and the liquid metal and so on, also may transport the liquid, the mixture of gases as well as contains the suspended solid liquid. Pump use in our lives is very wide, of course It also depends on the pump performance is good. Of course, you need to know what is a water pump is not only, it is also necessary for the general performance of the pump. The technical parameters of the pump performance capacity, suction, head, shaft power, water power, efficiency, etc.; According to the different working principle can be divided into volume pump, vane pump type, etc. Positive displacement pump is to use the studio volume changes to deliver energy; Vane pump is the use of rotary vane interaction with water to deliver energy, such as centrifugal pump, axial flow and mixed flow pump type.
Actually in the water pump, in use process will appear a lot of problems, so it's not just need you to understand what is a water pump, in understanding, on the basis of its performance, find out the reasons, which has a solution. For example: the pump suction is not water. Reason is that there is air in the pump body or feed line pneumatosis, or bottom valve closed lax irrigation water diversion discontent, vacuum packing serious leakage, a gate or door closed lax. Method: the water first, again will pump body filled with water, and then switched on. Check whether the check valve is tight at the same time, pipe, joint presence of air leakage phenomenon, leakage is found, after removal in tapping coated with lubricating oil or mixed paint, and screw down the screws. Check the pump shaft seal ring, such as severe worn should replace a new one. Piping water or air. May be installed when the nut is not tight. If leakage is not serious, but in a flat or a leaking place daub cement, or coated with asphalt mixing the slurry oil. A temporary repair can put some wet mud or soft soap. If the joint leakage, usable spanner tighten nut, such as leakage serious it must be to tear open outfit, replace the crack pipe; Reduce the head, to press the pump nozzle into underwater 0.5 m.
