Automotive Electric Water Pump Manufacturer

VOVYO Technology Co., Ltd is a automotive electric water pump manufacturer located in Dongguan city of China. We specialized in developing and manufacturing car electric water pumps, motorcycle electric water pump and other dc pumps. Most of our auto pumps are driven by a 12v , 24v or 48V bldc motor. Widely used in various vehicles, car, new energy bus, motorcycle, race car etc. Moreover, our automotive electric water pump has many function such as PWM/CAN/LIN control, idle protection, dry-running protection, etc.

Why Auto Electric Water Pumps Should Used on Vehicles?

1. As we all know, motors and control devices of new energy vehicle generate a lot of heat during work. It will affect the performance of the drive motor and reduce the life of the motor. Most seriously, vehicle will be self-ignite due to the short circuit. If the system can not the dissipate heat in time. Therefore, auto manufacturer use auto electric water pump as a hot water recirculating pump to pressurize the coolant to accelerate the dissipation of the heat.
2. Auto electric water pump can accurately match the operating conditions of the internal combustion engine and the running state of the vehicle. Besides that, it can achieve the goal of optimizing the engine installation space. Prolongs the service life of the engine, as well as saving energy and protecting the environment.
3. Compares with traditional mechanical water pumps, automotive electric water pumps have obvious advantages. Such as precise control of cooling effect, reduction of power loss of the engine, low fuel consumption etc.
4. Mechanical water pumps that rely on engines cannot work. Since motors drive the new energy vehicles runs. However, motors still require temperature control of the cooling system. Therefore, new energy vehicles must use car electric water pumps.
5. As we all know , the traditional machine water pump stops working, after the engine stops, and the warm air is gone. Although, some vehicles have auxiliary water pumps, these pumps still cannot be compared with automotive electric water pumps, since people still can continue to use warm air after the car stops if the car install with automotive electric water pumps. Therefore, it has an extended parking warm air function. And the electric water pump automotive will automatically work for a period of time after the engine flameout, and continue to dissipate heat for the turbine.
6. Car water pump is the core component of the automobile cooling system, and its role is to pressure boost for the circulation of the coolant (antifreeze). At current, most vehicles use a mechanical water pump. However, mechanical water pump has a flaw, that is it is not smart enough to stop working automatically when work in a cold weather. In order to solve this problem, high-end car models and new energy vehicles usually use vehicle electric water pump to replace the machine water pump, the former is powered by a motor and controlled by a computer module. In this way, the automotive electric water pump can be turned on and off according to the needs of the coolant temperature. And even the speed of the water pump can be adjusted to adjust the coolant pressure. Electric water pump for car generally driven by a brushless dc motors, therefore it does not require frequently maintenance and replacement like a mechanical water pump does.

What Types of Car Electric Water Pumps Are there?

People divide automotive electric water pumps into mechanical pumps and electric pumps according to the driving method. We further divide car electric water pump into brushless DC automobile water pump and brushed DC automobile water pump. According to the motor drive form of the water pump. People more commonly use the mechanical water pumps in traditional automobiles. While mainly use the latter  in new energy vehicles and some high-end vehicles.

Structure of Vehicle Electric Water Pump

Automotive electric water pump is mainly compose of rotor, stator, shaft,shaft sleeve, impeller, and pump body.

1. Rotor: The magnet of the BLDC pump is injection molded with the impeller and form the rotor of the motor.
2. Shaft sleeve: There is a direct injection molding shaft sleeve in the middle of the rotor. The shaft sleeve is made by a high performance wear-resistant graphite material.
3. Stator: Pump stator and circuit board of the motor are encapsulated in the pump body with epoxy resin glue.
4. Pump chamber: There is a chamber between the stator and the rotor. So, The rotor chamber of the motor completely isolate from the motor stator and motor control.
5. Shaft: People make the pump shaft by high wear-resistance and high-strength ceramic. It is completely sealed and leak-proof. Since the shaft connects the motor and the pump body directly. Thus it is no need to use traditional mechanical shaft seals.
6. Impeller: The vehicle electric water pump mainly uses closed impeller.

Advantages of Electric Automotive Water Pump

Automotive electric water pump is a kind of brushless dc pump. Which with advantages that mechanical pumps are incomparable.

1. Long life: Car electric water pump with life span more than 20,000 hours. Further more, it can continuously work for 24 hours per day.
2. No leakage: There is no leakage in the electric pump due to the advanced magnetic drive and statically sealed technology used for it.
3. Wide working temperature range: As a electric coolant pump, it can work in the temperature range of -40°C ~ 125°C. The engine preheating and parking heater pump can also work smoothly. Even under extremely harsh environmental conditions.
4. Polarity protection: It can protect the pump from burning due to the wrong connection of the positive and negative electrodes.
5. Energy saving: Electric automotive water pump has the advantages of energy saving, high efficiency and environmental protection.

5. Correctly calculate the purchase budget cost of the auto electric water pump. Inspect the pump manufacturer, require for good equipment quality, good after-sales service, supplying spare parts in time.

What special function should a Car Electric Water Pump have?

Automotive electric water pump usually work in a extreme working environment, which with high working temperature. This may lead to burn the pump even  the car and cause huge economic losses.

For example : On November 21, 2011, BMW (China) Automobile Trading Co., Ltd. submitted a recall report to the AQSIQ. Due to the technical defects of the turbocharger car electric cooling water pump. The total number of cars involved was 3,198.

Therefore, to avoid unnecessary economic losses, customer should consider below special function. When select a Auto electric water pump.

1. PWM Speed control function
2. Idle protection function
3. Stall protection function
4. Reverse connection protection
5. Over voltage protection function

Precautions for Using an Electric Water Pump Automotive

Automotive Electric Water Pump is a core component of the water cooling system for car, bus, vehicles etc. It has its own features and strict application requirements. Otherwise, pump will be damaged or short its life span under wrong operation. Therefore, you should follow the following eight points notices when operate the pump:

1. It is not allowed to use medium with impurities diameter bigger than 0.35mm or water with magnetic particles.
2. It is better to keep some water in the Automotive Electric Water Pump chamber before operating the pump after pump is not used for a long time.
3. It is not allowed to operate the pump without liquid for a long time.
4. Use dust cover to cover the pump when unused for a long time to prevent dust entering into the inlet and outlet.
5. Don not put the pump into liquid totally.
6. Confirm a correct connection before running, or malfunction may be caused.
7. Make sure that the liquid will not freeze or viscous when operate the pump in a low-temperature environment.
8. Clean the water stains first before operating the pump, if water stains left at the pins of the connector.
