1. Description of solar 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.
CNBM Solar Pump driven by infinite solar energy, works from sunrise, and stops at sunset, need no connection to grid power nor diesel oil and battery. System can irrigate directly or store water instead of electricity in a reservoir. Solartech Solar fountain Pumps works with sprinkling irrigation, drip irrigation and infiltrating irrigation facilities, can be more efficient for water saving and dramatically lower the cost of using fossil energy.

4. FAQ
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.
- Q: The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
- That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- However, the centrifugal pump will have its import pressure requirements, which is to prevent cavitation, that is, the fear of the delivery of liquid at low pressure will occur gasification. Centrifugal pump has an important parameter called NPSH, for example relating to the inlet pressure, the pump NPSH, 4 meters, it means that the absolute pressure of imports should be higher than the saturated steam conveying fluid pressure of liquid column is 4 meters high, so, when it is at a temperature of saturated vapor pressure for water transport 2 meters, 4+2=6 meters minimum inlet absolute pressure. Because the absolute pressure is 10 meters water column atmospheric pressure, at this time the entrance negative pressure is 10-6 meters =4 meters water column.
- Q: What's the meaning of the pump head in the water pump, please advise, thank you
- The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.
- Q: How is the pump level of submersible sewage pump determined?
- Pump water level must be higher than the water pump top, so that the motor running in the lower water temperature cooling environment, otherwise long-term operation will burn the machine
- Q: What is the difference between centrifugal pump and positive displacement pump?
- The centrifugal pump is to rely on high-speed rotation of the impeller to do work on the fluid. These two types of pumps are also the most widely used.
- Q: How many square cables does the submersible pump for 7.5KW need?
- I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).
- Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- First of all, we know that pump according to the principle of work is divided into speed and volume type, centrifugal pumps are speed type, and reciprocating pumps are volume type.The centrifugal pump can adjust the flow through the outlet valve and outlet valve opening can determine the pump flow and head performance curve parameters such as specific relationship between the outlet flow and pressure can be provided by the data pump manufacturers endplate that even close the outlet valve of the pump pressure will also have a fixed value, but not allow zero flow pump operation, vibration caused by damage to the pump on the mechanical seal is not good and so easy to cavitation, set the minimum reflux line.
- Q: How to maintain and repair the booster pump of pipeline pump?
- 4. install "0" ring, tighten the pump body and motor end cover with bolts. Notice that the clearance between the front cover of the impeller and the pump body is 20. 0.5 mm. The impeller inlet, the outer ring and the pump body ensure a certain running clearance.5. the disassembly order is the opposite.
- Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?
- Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
- Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
- Non negative pressure water supply equipment can be divided into non negative pressure tank and box type non negative pressure compensation device, steady flow tank type non negative pressure water supply equipment is the negative pressure tank, pressure tank can eliminate the negative effect of network equipment, is equipped with a vacuum suppressor and water protection box; non negative pressure water supply equipment has the advantages of simple device is a water tank with the boost voltage stabilizing device of complex box at the same time with no negative pressure tank.The tank type non negative pressure water supply equipment adopts vertical multistage centrifugal pump. This kind of pump is low noise and high efficiency. Such as CDL series and imported CR seriesOrdinary box type non negative pressure water supply equipment can use multi-stage centrifugal pump, also can use stainless steel submersible pump, submersible pump costs will be lower, but the maintenance costs will be high.
