< b ) br )< ) Features
> No maintenance required, small size, high efficiency, low power consumption, anti-interference Strong capability and smooth operation. No carbon brush, no pollution, electronic commutation, long life. Shock-absorbing silica gel absorbs vibration and reduces noise. The position of the silica gel is adjustable for easy installation. The stator and circuit board of the motor are potted with epoxy resin and completely isolated from the rotor, which solves the leakage problem caused by long-term diving of the motor-type DC water pump and is completely waterproof. It solves a series of problems such as the water pump getting stuck and suddenly not starting in complex environments. The water pump can be equipped with functions such as water shortage protection, idling protection, blocked rotor protection, and stuck protection. The water pump shaft is made of high-performance ceramics (a stainless steel shaft can be selected to reduce costs), which has high precision and good wear resistance due to the precise fit of the high-precision sleeve and ceramic shaft. The water pump parameters can be adjusted according to the requirements. The water pump can adjust the head of meters or meters of head, the volume remains unchanged, and it can operate at a wide range of voltages. This solves the mortality problem of water pump drivers. The mortality rate of water pumps currently on the market is about %~%. After a long period of scientific research, the mortality rate of water pumps has been reduced to less than 5 per 10,000. The three-phase Hall sensor-free program-driven DC water pump in the water pump series can realize speed adjustment, analog signal (~) speed adjustment, and potentiometer R manual speed adjustment, and the flow rate and head can be changed at will. The three-phase DC water pump in the water pump has soft start, no impact, low starting power consumption, and can be directly connected to the solar panel. The circuit board is completely separated from the pump body. There are no electronic components in the pump body. The pump body is made of high-temperature resistant materials. The water pump can Used in low water temperatures for a long time. It has impeller rotor stuck protection, reverse connection protection, overload protection and overcurrent protection. If you need to increase the pump lift, you can also connect the pumps in series, and the lift can be doubled. Amphibious (for external use, the installation position is lower than the liquid level). Water pumps and related control systems can be customized and designed according to user requirements. r/ /> < b ) br )< )

The above current is the opening current of the water pump, which is the current when the water pump is placed directly into the water without being connected to any system. It is also the maximum current of the water pump. When the water pump is connected to the system, the working current of the water pump will be reduced to % of the maximum load current. %.
The lift of the water pump is the maximum water delivery height, that is, the flow rate reaching the maximum lift point is zero.
The flow rate of the water pump is horizontal flow, that is, the flow rate of horizontal pumping water.
< b ) br )< ) The difference between a two-phase DC water pump and a three-phase DC water pump (sensorless intelligence)
: < : Two-phase (series)
: Sensor drive, circuit board must be built-in, speed cannot be adjusted intelligently
<: Three-phase (/series)
: DC three-phase and AC Three-phase is completely different. DC three-phase refers to sensorless drive. Its power supply method is the same as single-phase and two-phase water pumps, with only two positive and negative wires. Intelligent program driver, no sensor, the circuit board can be externally installed (the pump body can withstand high temperatures after being externally installed). Adjustable speed (~analog signal potentiometer speed adjustment) [Optional] Stall and reverse connection protection, overvoltage and overcurrent protection, overtemperature protection soft start, low starting current, no impact, especially suitable for direct power supply from solar panels< br/>

<< )Potentiometer speed control wiring method: (non-speed control water pump does not lead to speed control signal line)
The red line in the speed control interface is positive, and the yellow line is the speed control signal line , the black wire is the ground wire, the red and black wires are connected to both ends of the potentiometer respectively, and the yellow wire is connected to the middle of the potentiometer. In this way, rotating the potentiometer can make the voltage of the yellow wire slide between them, thus using the potentiometer to achieve this. speed adjustment in between. Do not touch the red and black wires together, as this may easily cause the circuit board to burn out. The potentiometer speed adjustment is the same as the R speed adjustment. If you use R speed adjustment, you only need to remove the potentiometer and follow the R speed adjustment method. Just connect the wires.
<< ) or analog signal R speed control wiring method:
(signal amplitude is) or analog signal speed control only needs to connect the yellow line in the speed control interface to For the speed control signal generation port (or) of the external control system, the black wire is connected to the system ground wire and the red wire is left floating. < b ) br )< < )Flow and lift curve
