The solar brushless water pump adopts a Hall element with high sensitivity and low power consumption, combined with efficient and intelligent electronic circuit drive, and adopts the volute design in hydrodynamics for the impeller cavity to reduce the resistance of water flow, so as to improve the overall performance by 20% compared with the efficiency of the traditional solar water pump. It also solves the disadvantages of difficult starting, low efficiency and poor stability of the current brushless solar water pump. The water pump can be connected with nozzles of different shapes to spray different water types. Solar panel specification: Rated voltage: 7V Rated power: 1.2W Material: polysilicon, pet laminated Pump specification: Working voltage: DC 7V Working current: 150mA Maximum lift: 100cm Maximum flow: 180L / h Service life of water pump: ＞ 20000 hours Water pump noise: ＜ 45dB Package size: Inner box size: 120 * 120mm Weight: 260g Product performance: Spray height: 30-60cm. When different nozzles are connected, the spray height will be different. When the solar panel receives enough sunlight, the water pump will start within 3 seconds. usage method: 1) Assemble the product according to the schematic diagram. 2) Place the solar panel in a suitable place to ensure that it is not obscured by other objects. When the solar panel receives sufficient light, the water pump works normally. 3) When the water pump is just put into the water, there is air in it, which may affect the spraying effect. It is recommended to connect the nozzle after the water pump sprays normally. matters needing attention: 1. This product is a solar direct drive water pump without an additional battery. The height of the water spray completely depends on the strength of the sun. When the sun is weak, the water pump will not work continuously, but will automatically start repeatedly until the sun reaches a certain intensity, and the water pump will return to the continuous working state. When using, please place the product in the unshielded sun. Shading will affect the normal operation of the water pump. 2. The water pump must be completely immersed in water and cannot be dehydrated for a long time. When the water pump is just immersed in the water, because there is air in the water pump, it is recommended to insert the nozzle after the water pump sprays normally. 3 please keep the water source clean and clean the water pump regularly to prevent foreign matters from being sucked into the water pump and causing the water pump to fail to work normally.
