1. When the car is running at high speed, the engine speed increases, and the heat dissipation of the on-board heating device also increases. When the car is running at low speed, the heat dissipation of the on-board heating device also decreases. Once the engine stops working, the heating unit also stops radiating heat. This kind of heating device, whose heat dissipation varies with the number of engine revolutions, cannot meet the heating requirements in the car in cold winter. Under normal circumstances, car owners will choose to install auxiliary water pumps to achieve stable heating in the cabin. Zhonglong automobile pump series auxiliary water pump still maintains a stable and efficient water circulation when the engine speed is very low, and continuously transmits the heat of the engine to the cabin, realizing the heating demand in the cabin when parking.
2. Automobile heating auxiliary water pump purpose to add an automobile electric heating water pump on the automobile heating water pipe, which has a simple and compact structure, is not affected by the engine revolution, and can stabilize the heating heat dissipation. The auxiliary water pump of the automobile produced by zhonglong pump starts within 10 seconds when the outdoor temperature is -40 ℃, and provides constant heating for the interior of the car without fear of severe cold.
3. When the auxiliary water pump for heating works, the motor drives the outer magnetic rotor of the magnetic coupling to rotate, and the magnetic line of force passes through the gap and the isolation sleeve and acts on the inner magnetic rotor to make the pump rotor rotate synchronously with the motor and transmit torque without mechanical contact. At the power input end of the pump shaft, because the liquid is enclosed in the static isolation sleeve, there is no dynamic seal, so the medium is completely in the sealing cavity and there is no risk of leakage. At the same time, zhonglong automobile water pump adopts imported raw materials to ensure the stability and batch consistency of the water pump. PPS raw materials imported from Japan overcome the shortcomings of being unable to withstand extreme cold and high temperature, making the pump shell of zhonglong pump durable and free of cracking risk. The various protection functions of the water pump can easily cope with various complex circuit conditions, ensure the stable operation of the water pump, and realize the continuous heating demand in the cabin.
