Design
Single- or multistage centrifugal pumps in ring-section design, single entry; for vertical and, depending on the number of stages, angled and horizontal installation; mixed flow hydraulic systems available with reduced impeller diameters; driven by submersible motors. Suction casing fitted between pump and motor, equipped with strainer to protect the pump from coarse particles in the fluid. Permissible sand content in the fluid: 50 g/m³. Pumps with non-return valve or connection branch on option.
Applications
pumping clean or slightly contaminated water in general water supply, irrigation and spray irrigation systems, lowering and maintaining ground water levels, pressure boosting, emergency water supply, as well as mines and fountains etc.

Q:Rules for operation of centrifugal pumps: Operating rules:1, before starting to check whether the water pump foot loose, coupling shield, and motor fan blade cover is intact, in order to ensure the safety of equipment and personal safety.2. Check whether the inlet valve is open and open as fully as possible. Is the outlet valve closed, open the bleeder valve, exhaust until there is no air, and close the bleeder valve. At the end of the valve to the pipeline in the pump cavity filled with water.

Q:The main factors affecting the performance of centrifugal pumps: The specific speed is deduced by the law of hydraulic similarity, and the similarity between the hydraulic characteristics of centrifugal pumps is similar. In centrifugal pumps, the specific speed is often interpreted as: the pump works at the highest efficiency, generating a lift of LM, a flow rate of 0.075m, and the power consumed by the /s at 0. 735kW

Q:What does electromechanical vector pump mean?: It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.

Q:How to calculate the motor power of metering pump?: Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw

Q:How many pumps does the 80cm tank use?: Filter pump to select the water per hour can be filtered more than 3 times, I personally feel that this is almost enough. Of course, the more times the better, but also consider that if the pump is too large, the water inside the tank will be too large.128X3=384LThat is, the flow must be more than 384L/H of the water pump.You can buy a bigger pump, because the pump for a long time there will be some attenuation and domestic things in general to sign data, so it should be based on your actual situation to buy. Taobao on this category is about 20~40 yuan.

Q:What is a water pump coupling device?: The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove

Q:What is the principle of a turbopump?: The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.

Q:Know flow and lift how to calculate the pump power?: N=Q.H.g. P / nN - motor power, kWH - pump head, MQ - pump flow, m^3/sG - gravity acceleration g=9.81

Q:Fire hydrant pump button, under what circumstances do not need to install?: General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.

Q:What are the parts of a pump? How do you classify it?I just want to know: According to the working principle can be divided into: centrifugal type and volume type centrifugal pump. By the centrifugal force of the impeller will accelerate the refrigerant, through to stay, so as to achieve the purpose of boosting; volume by changing the refrigerant in the flow volume to boost purpose.According to the media and installation conditions, water pump: centrifugal pump used: the impeller pump shaft, a curved blade on the impeller impeller outlet. The central entrance water vertically along the tangential direction of axial flow pump: high speed, large flow, low lift, mixed flow pump and centrifugal pump structure similar to that of the blade outlet angle is different, wide flow channel, close to the performance of axial flow pump displacement pump: safety valve must be opened before the start (metering pump, screw pump)
