When discussing the technological progress and application selection of DC water pumps, brushless and brushed water pumps have become our focus. Brushless DC water pumps are those water pumps that use DC as a power source. Through the adjustment of the control system, these water pumps can drive the motor to rotate, so that the impeller can operate, relying on the pressure difference to achieve the suction and discharge of liquid, and finally achieve the purpose of liquid transmission.
- Compared with ordinary brushed water pumps, brushless water pumps have the following advantages:
1) The pump shaft is changed from a dynamic seal to a closed static seal, which completely avoids medium leakage. It can be used both in water and water and is completely waterproof. The stator and rotor parts of the magnetic isolation water pump are completely isolated, and the stator and circuit board parts are encapsulated with epoxy resin, which is highly waterproof.
2) Low power consumption and high efficiency, no independent lubrication and cooling water are required, and energy consumption is reduced.
3) The brushless DC water pump uses electronic component commutation, and no carbon brush commutation is required. The rotor part uses permanent magnets, and the water pump body uses environmentally friendly materials. High-performance wear-resistant precision steel shaft and sleeve are used. The sleeve is connected to the rotor as a whole through injection molding to avoid wear, so the life of the brushless DC magnetic water pump is greatly enhanced.
4) It has a damping and vibration reduction effect, which reduces the impact of motor vibration on the pump and the impact of cavitation vibration on the motor when the pump occurs.
5) The noise can be as low as 35dB.
6) Various required parameters can be adjusted through the winding of the stator, and it can operate at a wide voltage.
7) When overloaded, the rotor will slip on the ceramic shaft, which has a protective effect on the motor and pump.
- Brushless DC water pumps have the following characteristics:
1) Low-voltage DC power is used, which is safer, more efficient and less noisy
2) No carbon brushes, no carbon powder pollution, and the service life is usually more than 30,000 hours (taking the brushless DC water pump of Zhonglong Pump Industry as an example)
3) The motor is completely isolated from the conveying medium, with a static seal design, and no leakage during long-term operation
4) Built-in chip, which can be linked to different external inputs, and PWM broadband control is applicable to a wider voltage
- Possible causes of failure of brushless DC water pumps that cannot pump water:
1) The centrifugal brushless DC water pump body is not filled with water
2) The distance between the brushless DC water pump and the water surface exceeds the allowable installation height of the brushless DC water pump, or does not meet the water pressure required for the brushless DC water pump to pump water.
3) There is foreign matter blocking the impeller or the water inlet of the brushless DC water pump, or the pump inlet valve is closed.
4) The gap between the impeller and the pump casing in the pump is too large, and the inlet and outlet channels are straight.
5) The pipe from the water inlet of the brushless DC water pump to the water source is damaged, causing it to inhale a large amount of air.
6) The key connecting the shaft and the impeller falls off or is damaged, and the motor does not drive the impeller to rotate.
Q1: What is the reason for the repeated start and stop of the brushless DC water pump?
A1: The brushless DC water pump you purchased has a protection function. It will start and stop five times and stop completely in the case of water shortage, jamming, blocking, and idling. If you need to restart the brushless DC water pump, you need to connect the power again, and ensure that there is no water shortage, jamming, blocking, or idling before it can operate normally.
Q2: Why did the brushless DC water pump suddenly stop working during operation?
A2: There may be various situations such as water inflow into the controller, rotor jamming, impeller breakage, etc. If you need to understand the specific situation, you need to return to the original factory for inspection.
