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: How to adjust the flow of piston pump?: Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.

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: Variable flow pumps are variable pumps: Yes. The variable pump is designed to change the flow rate

Q: Water pump outlet valve sequence: Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.

Q: What kind of motor does the hydraulic pump need?: Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused

Q: Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!: 3. efficiencyVolume efficiency, for hydraulic pumps, is the ratio of actual flow to theoretical flow. A hydraulic motor is the ratio of its theoretical flow to its actual flow.Mechanical efficiency, for hydraulic pumps, refers to the ratio of theoretical torque to actual input torque. The actual output torque of the hydraulic motor is theoretical torque to overcome the torque after friction, so the mechanical efficiency is the ratio of the actual output torque to the theoretical torque.

Q: What is the function of the heating pump system for the water pump design?: As the feed water temperature is higher, in the case of non warm pump start, will make the pump body is subject to greater thermal impact; in addition, the flow components with the pump contact heating fast, not contact with water directly heating slowly. This expansion due to uneven speed, it will inevitably produce thermal stress, deformation of the pump body, sealing surface, the joint surface is lax and leaking phenomenon. Therefore, the warm water pump system is designed for the water pump.

Q: What is the pumping property of concrete?: Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.

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

Q: What are the failures and causes of the replacement of the fuel pump assembly?: Common troubles of gasoline pump:Gasoline pump supply shortage of gasoline pump supply depends on the pump membrane stroke, stroke, pump oil should be more; however, the amount of gasoline pump oil pump will reduce the consumption of gasoline engine, and the fuel pump is inevitable, if the engine fuel consumption, but the actual amount of oil is less, this situation is the amount of oil in the petrol pump, there will be a float chamber of a carburetor oil level is reduced, the engine power shortage.
