How to select a electric water pump for a new energy car?

Electric water pump is an important component in new energy vehicles, mainly responsible for the circulation of the cooling system to ensure the normal operation of the engine. Compared with the traditional mechanical water pump, the electronic water pump has higher efficiency and lower energy consumption. At the same time, it can also be linked with other control systems to realize more intelligent functions.

The key elements of electronic water pump selection guideline as following:

1. Flow: flow is the most basic elements of selection, according to the model and engine power to determine the needs to take into account the speed, engine load and other factors.

2. Head: head is another important parameter of the electronic water pump, which indicates the pumping liquid can overcome the resistance to flow and the pressure generated by gravity, generally to safeguard the engine cycle at different speeds.

3. Voltage: selection needs to be considered when the vehicle rated voltage is consistent with the voltage requirements of the car water pump.

4. Environmental adaptability: As the bldc water pump in the vehicle working process of the environmental conditions are relatively harsh, so you also need to consider the pump itself high temperature resistance, vibration resistance, waterproof and other properties.
