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.

4. FAQ of DC/AC Solar Irrigation Submersible Pumps

1> Can your pump work automatically?

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

2> 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.

Q:The reason why the pump is overloaded
The description of the problem is very clear. Most of this kind of circumstance is overload, is also the outlet pressure is very low, the flow is greater than the rated value caused by the resistance can be adjusted by increasing exports or close the outlet valve, reducing the flow resistance increased by less than or equal to the rated flow. Lift is not an influencing factor.
Q:What are the categories of pumps?
First, select the pump to meet the requirements of the headThe so-called head refers to the required lift, and not lift the water height, clear this point, the choice of water pumps is particularly important. Pump lift is about 1.15 to 1.20 times the height of lifting water. If the vertical height of a water source to the water is 20 meters, the required lift is about 23~24 meters. When selecting a pump, the pump head should be close to the required head, and the general deviation is not more than 20%. In this case, the efficiency of the pump is the highest, and it is more energy efficient, and the use will be more economical. If the lift on the nameplate is much smaller than the required lift, the pump can not meet the needs of users, even if the water can be pumped, the water is also very poor. But in turn, the high lift pump for low head, there will be heavy traffic, resulting in motor overload, if long time operation, the motor temperature, the winding insulation layer will gradually aging, and even burning motor.Two, select the appropriate flow pumpWater pump flow, that is, the amount of water is generally not too large election, otherwise it will increase the cost of water pumps. Should be selected as needed, such as the use of the user's family self-priming pump, the flow should be chosen as small as possible; if users use the submersible pump irrigation, you can properly select a larger flow.
Q:2 inches of water pump is generally equipped with high-power motors
Clean water pump 5.5 kw
Q:I have a mechanical well how to choose the size of the pump
First, determine the size of the electrical well and then the depth. Is it water injection or pumping?The pressure of water injection pump is much higher. If you pump water, it depends on how much water you need every hour Plus you enter the water depth of +10 meters, you can basically a good selection.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
3, sewage pump flow per hour 40 square water head 15 meters, 1600 rpm, with power 4KW
Q:How to introduce water pump?
Using the results of 1, in the past, the general company will make a performance table, in which use the same type of pump operating conditions and you almost use down till now there have been no problem, what you can say.2, reliability. Power plants may care more about the reliability of the equipment than on the price of the pump. Of course, the technology and procurement of power plants are not stupid. They will weigh it themselves.3, pump efficiency. Because the general pump special large pump involves a power plant called "factory power consumption" index, the smaller the better the index, and your pump if it is efficient, it will reduce the target, the power plant may be interested.4, if you want to sell the pumps have their own technical characteristics, you can also be appropriate to describe it, but if you are a salesman, but the technology is not very proficient in it, and the best little power plant technical personnel, because they ask if you can not answer, its effect is counterproductive.
Q:What is called soft start of water pump?
Soft start is a form of electronic control, mainly through the soft drive to achieve. Principle: the former contactor is directly started as contactor, first pull in, and the device is started by soft driving. Soft start device start smoothly, starting current is small, control system life is long. Soft start is now in widespread use. But the use of high-power equipment is less, the general current is less than 120A.
Q:Relationship between pump voltage and lift?
This is the world's Grundfos pump, if the pump itself support work under the 414V if it didn't need to worry about traffic and Yang Cheng, if the pump does not support the long time operation of the pump must lift and flow impact, and the multi-stage pump if it is Gao Yangcheng in the use of low lift it is also easy to burn the motor,
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
Q:Pump performance parameters have three sets of data, how to understand the flow, lift, flow speed
1, the head is composed of a water pump design decisions, such as motor speed, power, blade shape; the flow is determined by the motor power and lift, the same power lift higher flux is small; velocity determined by flow and pipe section with a pump pipeline section greater velocity.2, the pump is to transport liquid or liquid pressurization machinery. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
