Specificaion Solar water pump consists of solar panel system, PV water pump controller system and pump. 1. Solar panel system: Solar arrays are in series-parallel ofsolar modules; transfer the solar energy power to electricity to supply power for pump system. 2. Photovoltaic water pump controller system: it regulates all the pump system, turning instable DC voltage of solar panel system into stable DC voltage for pump, and regulates the output current in according with sunshine intensity to achieve maximum power point tracking(MPPT), maximizing the use of solar energy. 3. Solar pump system: it consists of pump body, motor, water pipe, cable, protection devices, water level sensor.
Application: The solar pumps can automatically work in the day, while the sunshine is lower. So it is suitable for irrigation, garden, fountains, family, pastoral grasslands, mountain, especially working in the areas without electricity supply.
Products feature: 1. Water pump controller system has complete electrical protecting device, against under-voltage, over-voltage, over-flow, overload, waterless, etc; also with an automatic switch and water level sensor that can on/off the pump when the well is dry and the water tank is fully. 2. Pump head: 10-180m, Flow rate: 1.8-60M3/h. 3. Working temperature:-20-50
Service life: Solar panel: 20-25years; Pump comtroller: 10years Water pump: 30,000hours

Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
Q:Pump operator's responsibility Sharing the rules, responsibilities, etc..
3. master the operating rules of the pump operation, and make sure the pump position is reasonably determined. Do a good job of site investigation, find out, pay attention to.4. master the working principle and basic technical parameters of the delivery pump. Obey the command of production dispatcher to ensure the completion of production tasks.5., according to the number of tanker at the scene, determine the pumping speed, in order to ensure the continuity of pouring.6. normal pumping, the discharge rate should be uniform, to prevent uneven discharge, resulting in pressure pipe gas plug, and thus lead to pipe or pipe explosion accident.
Q:How many millimeters is the diameter of the water outlet of the four inch pump?
Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.
Q:What is the difference between centrifugal pump and rotary vane pump?
The vane pump can be divided into centrifugal pump, mixed flow pump and axial flow pump according to the direction of liquid flow in the impeller.Centrifugal pump is a kind of vane pump, which is the most widely used.
Q:What is the lift of diaphragm pump?
Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.
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 difference between the ground pump and the pump in the commercial concrete?
What you should say here is the concrete pump.Ground pump: the pump will be placed in a position on the site, the pipeline will be sent to the construction of concrete surface,
