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.

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> May we ask if the bare pump or the whole pump system would be all right for you to arrange the delivery?

     The bare pump and the who systems would be all acceptable at your side. A controller will be equipped with the pump freely. Regarding the whole system, we can also make the best solar panels configuration according to your requirements. 

2> Does your controller have the MPPT Function?

     Yes, our controllers have. This would be not a problem. 

3> Can your pump work automatically?

     Yes, it would be the basic advantage of solar water pumps. 

4> 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.

5> 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.

6> Do you have pumps with grinders?

     Yes, the WQ models.

Q:97 dodge van 3.9 water pump?
I,m with JOHN R in this one, confirm your radiator fan seize is working and not purely unfastened wheeling all of the time and additionally confirm that there is no air trapped interior the cooling gadget.With engine off crack a heater hose unfastened close to the heater center and pour anti freeze in until it starts to return out the disconnected hose. And the cooling fan could become noticeably louder whilst the engine is heat and in case you shut the engine off it is going to experience stiffer to coach than it does cool. sturdy success.
Q:Work done in water pumping?
Power_W = (Mass_kg * Gravity_m/s/s * Height_m) / time_s Where: Mass kg is 1kg/l of 2000 liters Gravity is 9.81m/s/s Head is 60m + 10m (height). The suction head is ignored because the pump is submerged. In practice there is some suction head due to intake restrictions like pipes, check valves, strainers. The time is 20 minutes in seconds. The work is the energy used in the time allocated, which is: power * time in seconds, which is watt seconds = joules. Not needed here as it is in the formula above. Power is the rate of doing work. The depth below water is not really relevant except for pipe losses which increase the head slightly. The flow is 2000 liters/20 minutes = 100 l/min. This can be used with the head of 70m to determine the pipe restriction, which amounts to a pressure drop representing extra head added. It will indicate whether the pipe is too small (excessive head added) or whether the pipe is overkill (no head added). You can find on line calculators for this, e.g. search pipe resistance flow on line calculator. I am guessing a 2 inch pipe has little loss at this flow. This is the so called water power. It is the output power of the pump. The pump may only be 50% or so efficient, so the mechanical power delivered by the motor needs to be greater by this ratio. The electrical input power to the motor is greater again to allow for motor efficiency. This might be 60-90%. In practice the efficiency of pump and motor are determined from user manual or specification of the actual devices with the actual loads (head and flow).
Q:1997 Civic-Timing belt/Water Pump?
water pump is usually replaced with the timing belt since it is easiest to get to when you are doing the timing belt. your water pump may go out on you tomorrow or last for another 300k miles, who knows. but with it not having been changed, you are still riding on a pump with 138k on it. lots of miles on that impeller. if it lasts, just have it changed next timing belt...which I would do @ around 160k miles ~ 80k is about right for a timing belt to last. civic water pumps are cheap...as are the timing belts.
Q:WHERE IS A GOOD LOCATION TO PURCHASE A WATER PUMP AND HOSES FOR A 1998 CHYSLER TOWN & COUNTRY.?
Best affordable place: OKorder.
Q:Is the pump lift horizontal or vertical?
The vertical height from the center line of the pump impeller to the surface of the water source
Q:do i really need to replace my water pump?
You can do that, but you can't fill it with pure water because in time you'll have only water in the system which can cause problems. Antifreeze also increases boiling point of the water/antifreeze mixture thus protecting the engine... You should always add 50/50 mixture. Anyway, bad pump is generally bad for cooling. It is better to have leaking radiators than bad pump.
Q:Relationship between pump voltage and lift?
Our CRN series water pump 1, 480V 60Hz in 414V 60Hz power supply, won't have what effect, only voltage drop corresponding to the current rise. Water pump head will not decrease.2, the water pump voltage and head have no direct corresponding relationship.
Q:1991 Ford Taurus SHO water pump?
It's fairly simple and straightforward to replace a water pump on most vehicles. An older one like that will be even easier. Take off the belt and any other brackets or parts that obstruct the removal of the water pump and then unbolt the pump itself. Clean the gasket surface area, install a new gasket, and then reinstall in reverse order. You will need a good mechanics tool set with sockets and wrenches(mostly metric), a pry bar, a drain pan, and a good repair manual like a Haynes or Chilton and you will have a pretty easy time with it. A garage will charge about $90 to $105 an hour for any job. You can call a dealership and ask them and they will give you a price based off of the estimated time and part cost. Since most private garages and the dealers charge about the same hourly rate the better choice is almost always the dealer.
Q:help with water pump on 1992 Toyota celica?
in case you'll locate the Chilton guide for that vehicle, it ought to have all the tips you opt for to finish that restore. because of each thing going to digital cataloging, many previous severe college save preparation no longer use the Chilton books they have. they frequently carry an complete library of them. see in case you'll get a loose one from the community severe college.
Q:How do I calculate the power of the pump?
Power P (kw) =9.81*Q (second cubic meter) *H (head, unit m) / efficiency;The efficiency can be found on the pump nameplate or sample.This is the rated power, if the head down, the flow increases, the power will increase, so the actual motor power is often much larger than this calculation.Generally buy pumps are equipped with motors, manufacturers can refer to the same model or similar models of motor power.
