① What is your product range?

Centrifugal pump, slurry pump, gravel pump, clean water pump, sewage pump, chemical pump, single stage

pump, double suction pump, industry pump, oil pump, paper pulp pump, mud pump, self-priming pump, pipe

water pump, boiler water pump, etc.

② Are you a manufacturer?

Yes, we have been in manufacturing and marketing industry centrifugal pump over 20 years.

③ What information should I let you know if I want to get a quotation?

Pump capacity, pump head, medium, medium temperature, pump material, quantity, if possible, please also

provide the pump model you are using now, price will be calculated as per the pump model, if not, we will recommend relevant product for reference.

Q: Why does the centrifugal pump close the pressure to start?: The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.

Q: What is a water pump coupling device?: The automatic coupling device of the water pump coupling device has compact structure and small occupation area. The sump pump works because it is submergedThe utility model can be directly installed in a sewage pool, and no special pump house is needed to install a pump and a machine, thereby saving large amounts of land and infrastructure expenses

Q: What are the internal losses in centrifugal pumps? How did they come about?: Volume loss: loss due to leakage;3. mechanical loss

Q: What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?: Large pump control valve controlled energy consumption at least 30% reason is that there are serious throttling loss of a throttle valve control system of severe fever but simple structure and low cost which is why now valve control system still occupy the main market reasons.Pump control system with complicated structure especially when serious nonlinear control unsymmetrical cylinder control effect is not ideal, but the biggest advantage is energy-saving and low fever America professor Monika points out that using the pump control system of hydraulic excavator energy efficiency compared with the valve control system can be improved by over 46% but costs are high. But in control, the three pump invented by Professor Quan LONG of China is a good solution. LZ can find the invention patent or find his paper on sage. It seems that there are three or four SCI about this pump

Q: The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?: High speed rotating impeller blade drives the liquid to rotate, and the liquid is thrown out so as to achieve the purpose of conveying. There are many medium for transportation, such as oil, water, chemicals and so on. The pump shaft and the motor shaft are of the same shaft, the pump and the motor are made into an integral body and immersed in water. The medium of transportation is water.

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: I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?: Constant pressure pump is pressure maintained at the set pressure, flow control valve according to the order, there is pressure to set, after the pump displacement is reduced, as for how to reduce emissions, to see how much you need to flow.

Q: How to install, operate and maintain the pipeline booster pump?: When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.

Q: What is pump suction work?: Pump is mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.

Q: What is a feed pump?: In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
