Product Description:

1.  Description for DC/AC Solar Irrigation Submersible Pumps. 

CNBM Solar Water Pump is the pumping facility driven by solar energy, which consists of a solar pumping inverter and a pump. Solar water pumps kit is called  solar pumping system combining with solar arrays designed according to different head and daily water flow for application. System is widely utilized for agriculture irrigation,desert control,pasture animal husbandry,city landscaping,daily water supply, etc.

 

In recent years, with the development of photovoltaic products from city application to huge demands of agriculture,pasture,desert areas, CNBM Solar Pond Pump has become the leading products combining photovoltaic industry with traditional industry such as agriculture water conservancy,desert control,daily water supply,city landscaping, etc.

 

2. Technical Function of DC/AC Solar Irrigation Submersible Pumps. 

1>  High efficient DC brushless motor requires less solar array. Rich social benefits.

2>  Optional centrifugal pump for big flow and helical rotor pump for high lift.

3>  High efficient semiconductor device used in main circuit. High reliability. Up to 98% conversion efficiency  of controller.

4>  Independent intellectual property of dynamic VI maximum power point tracking (MPPT) algorithm. Fast  response  and good stability. 99% MPPT efficiency.

5>  Full automatic operation. Complete protection functions. Integrated with water level monitor to prevent

  overflow and dry running.

6>  Full aluminum alloy case. IP52 protection grade. Ambient temperature: -20~+60.

Product Specifications


3. Specification details for DC/AC Solar Irrigation Submersible Pumps. 

1> Flow: 0.4m³/h~22m³/h

2> Head: 10m~210m

3> Power: 0.1~3Kw

 

4. FAQ of DC/AC Solar Irrigation Submersible Pumps

1> Is it really necessary to fit a bleed valve for the boxes?

     It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

2> If I increase the power of the motor, must I also increase the power of the inverter?

     You must select the size of converter that allows maximum absorption of the electric motor.

3> Do you have pumps with grinders?

     Yes, the WQ models.

Q:Domestic pump does not turn, but the motor is energized what is the problem?
The motor is sure of electricity, isn't it? Is there a low voltage or broken phase (three-phase motor), these cases will cause the motor does not turn, or low speed (easy to block), so should be measured with a universal meter. Maybe the boot capacitor is broken. Or smell the smell of burning. It might be a short circuit between the motor windings. (bearings should be hard to break). Look for repairs if you suggest. You may not be good. Oh, capacitor. You can measure good and bad with a universal watch. If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter.
Q:Thermostat or water pump problem?
Either the water pump... Or it could be the radiator that might not be performing as well.
Q:im changing my water pump on 97 cadillac need help?
You sure you have the right tool?? There are 2 different tools they came out with. Cant remember the year but Cadillac changed the water pump design which the tools had to change. Neither one will work on the other design. Both almost look the same except the teeth stick further out on the older design. I always use a impact, put the socket on your impact just bump the trigger enough to get the pump to turn a little. But not too much or you'll break the ears of the housing then you'll have to replace the crossover asy I did see you said CLOCKWISE!!!!!! Make sure you are turning it to the direction to tighten, this has the reverse on/off direction
Q:Why can domestic pumps sometimes pump water and sometimes not?
This fully automatic self-priming pump, if there is no water, there are 4,A. The air in the pump cavity is exhausted. The solution is to unscrew the copper screw on the pump body,Two. Water pipe leakage solution, check the joints and piping to ensure reliable sealingThree. At the end of the valve or three does not open or there is a serious blockage, solutions to check the bottom valve goods three psychic activity,Four. Leakage of seal in pump, adjust or replace the sealWhat's more, you feel that there is a leak in your water inlet. Check the three pass on the water inlet of the water pump. Think of this fully automatic pump. The switch for your tap water can be kept open all the time
Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?
Why not share mainly because the two impurities contained in the water system: fire hydrant system requirements of different impurities in the water spray system requirements loose, but more stringent requirements, therefore, the former can be welded steel pipe, the latter must use galvanized pipe, the purpose is to prevent rust plug flow indicator or end of the spray head.
Q:How do I calculate water volume pumped?
Use the Bernoulli equation, aka mechanical energy balance.
Q:How serious is a broken water pump on a car?
Broken Water Pump
Q:A direct type pump model with the coupling type, what is the difference?
The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.
Q:Pump impeller diameter plus assembly what changes? What's the effect on the motor?
1., the larger the diameter of the impeller, the greater the head, the greater the flow rate, because the flow of water depends on the speed of rotation of the impeller generated by the centrifugal force and the line speed on the tangent, the greater the diameter, the centrifugal force and the greater the speed of the line. The relationship between the centrifugal pump water delivery and the vacuum degree is that the centrifugal pump is the centrifugal force principle to complete pumping. Without water, the time and space turn will burn out the equipment.2., the head and impeller diameter is related, the larger the impeller, the greater the head, and vice versa. The flow rate has little to do with the impeller diameter. Under the rated conditions, the greater the head, the smaller the flow rate, inversely proportional.
