Q: Must the water pump in the tank be all soaked in water?: Need a submersible pump in the water, but it is not entirely like this, I have to work for a long time no problem in water, but there is a problem you should pay attention to the water pump, at least in half, or stop when the smoke is not on water.

Q: What are the general water pump failure, how to repair?: Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.

Q: What should I pay attention to when buying a pump?: There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.

Q: Water pump outlet valve sequence: In order to prevent the generation of water hammer when the pump stops the damage to the rubber head, should be immediately set rubber head pump outlet, the gate valve and the check valve is not a very convincing reason to decide the order of habits in our hospital order rubber head, check valve, gate valve1. Check valve located in front of the pump, I do not know what the significance is too great to think of.2. The actual installation sequence shall be: soft fittings, check valves, gate valves. The pressure gauge is best installed on the water outlet of the pump, but it must be in front of the check valve.Reason: 1) the soft joint is used to reduce vibration. The connection between the pump and the piping system, of course.2) normal work, the gate valve is not operating, and the check valve is frequent action, so the probability of maintenance is larger, when the maintenance of the pump closed, the water outlet valve can be maintained without affecting the normal operation of the system.3) the pressure gauge is installed in the check valve, which can prevent the impact and damage of water hammer on the pressure gauge.

Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?: When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal

Q: How many kinds of pumps are available and the operating principles of various pumps?: The volume type pump, depending on the periodic change of sealing liquid containing space volume, the energy is periodically transmitted to the liquid, the liquid pressure increased to force the liquid discharge, according to the motion form of work elements can be divided into reciprocating pump and rotary pump. Other types of pumps transmit energy in other forms. As the jet pump work on high-speed jet of fluid will be required to transport fluid suction pump after mixing for momentum exchange in order to transfer energy; water hammer pump by water when braking in the flow of energy transfer is to rise to a certain height; the electromagnetic pump is energized to make the liquid metal in the electromagnetic forces generated in the flow and transport. In addition, the pump can also be classified according to the nature of the transmission fluid, driving methods, structure, use and so on.

Q: Is the centrifugal pump large or small?: NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.

Q: How many concrete pump tube diameter: The pump tubing diameter is 125MM general concrete or mortar pump tube diameter is 80MM fine stone

Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you: And the pump at the start, if the valve opening pump, then the pump outlet pressure (head) is very small, so the pump flow will be great, the pump power is very large, causing the start-up current is very large. In addition, the starting current of the motor itself is also very large. These two factors add up to the possibility of overloading the motor, resulting in failure to start or even burn the motor.

Q: Attention should be paid to the use of pumps?: To carefully check whether there is a crack impeller, impeller fixed in the bearings are loose, if there are cracks and loose, hungry phenomenon should be promptly repaired, if the pump impeller above the soil should also be cleaned
