Products

DC Solar Pumping System can be applied to daily use (ground water), agricultural irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering, and so on. Solar water pump System is dispensed with energy storing devices, and stores water instead of electricity. It improves the reliability of the device, at the same time, it lowers the construction and maintenance costs of the irrigation system dramatically.

In recent years, with the promotion of the utilization of new energy resources, Solar Pumping System is more and more used in municipal engineering, city centre squares, parks, tourist sites, resorts and hotels, the landscapes and fountain irrigation systems in the residential areas.


Technical Features

Optimization of Single Pump System


A single solar irrigation system consists of only one pump, a power -matched solar array and an inverter . The aim of optimization is to reduce the amount of PV modules as much as possible on the premise of filling the requirement of head and capacity. The rotational speed of pump is regulated according to the irradiation on the solar array; when the sunlight reaches its peak, the pump runs at the rated speed, and the output approaches the peak power of the solar array; when the sunlight is less abundant, the speed of pump varies bellow the range of the rated speed; when the speed as low as the capacity becomes zero, the solar pumping system stops working. So, there are big differences between solar irriation systems and traditional pumping systems in system design, and the system should be optimized according to the requirements of head, capacity, and local conditions of sunlight.


•Determine the optimal average daily operating time and the range of speed governing.
•Choose the optimal head and capacity of the pump.
•Determine the maximum power of PV modules, the best working voltage and method of connection.
 
Optimization of Multi-pump Systems:
There are several pumps in a multi-pump system. The pumps can be driven either by only one high-power inverter, or by several matching inverters. In the case of large capacity demand, the operation of the multi-pump system is more flexible. By switching solar arrays and pumps, all of the pumps run in MPPT mode when the sunlight is abundant, while some pumps will be shut down and all solar arrays supply power intensively for the rest running pumps when irradiation is weak. Based on the optimization of single pump system, the range of speed can be further optimized, and the photovoltaic(PV) pumping system always works with high efficiency.

Q:Will the next solar hot water system, the solar energy pump how to select the number,
Generally need to calculate the total flow according to the collector area, a reasonable division of the branch and divided by the number of branches to calculate the branch flow, according to the collector test report on the flow resistance curve calculation and series calculation of the collector pressure drop;
Q:Does the balcony wall - mounted solar energy require a circulating pump?
Now the mainstream balcony wall is a natural cycle, so do not need to install the circulating pump. Circulation pump is used to do the forced circulation. The so-called natural circulation, is your home balcony collector (flat collector or U-tube collector) to absorb solar light heat, the collector medium using cold water sink hot water floating automatically heat will be passed to the tank in. If your collector is higher than the tank, or because the pipeline climbing and other reasons can not be a natural cycle, it is necessary to increase the circulating pump. Solar energy in the natural cycle of the best, plus the pump is not good. Waste money, and easy to bad, if the bad quality and noise.
Q:Booster pump installed in the solar water heater, the correct location should be where the solar water heater?
Tip: Now most of the solar energy for the water-type solar, water need to consider the problem of booster pump, bring a lot of trouble;
Q:Solar water heater booster pump how to use automatic valve
The general flow control of the booster pump can not be used, with the general self-priming pump can be, if installed on the charge, when the solar energy needs water, open the other faucet, you can press the solar up, or
Q:Solar water heater computer controller shows Sheung Shui, booster pump does not start Sheung Shui, how to do
First look at the control panel signal line is not bad contact, check the water level probe, if these aspects are no problem, then you turn off the power after 3 minutes, at the start.
Q:On the issue of pumps and solar panels
Pump head and power sure and pump power and methods such as centrifugal pumps ~ but this full business can give you recommended.
Q:How does the solar self-priming pump be installed?
Installation to minimize the hydraulic loss of the suction pipe, not less than 90 ° elbow, 90 ° elbow on the import pipeline should not be more than 2, the pump inlet should be set to filter, to prevent large impurities into the pump , To ensure the normal operation of the pump, the installation as much as possible to reduce the import pipeline long way (this will reduce the import pipeline air, thereby reducing the self-absorption time, increase efficiency).
Q:What is the pump for solar hot water
can be loaded with pressure type. Its principle and electric water heaters, gas water heater is the same. Water pressure is particularly large.
Q:What is the role of solar water pump?
Do not produce any solid, liquid and gas harmful substances, absolutely environmentally friendly.
Q:The problem of installing pressurized water pump in solar hot water outlet pipe
Household pipe booster pump in the installation of the need to pay attention to the matter more, but these considerations for the subsequent work and production of great impact, we often say that sharpening workers do not mistake. Only to the precautions to prepare thoroughly, for the use of the product we can be more handy, the effect will be better.
