Function Description
| 1 | Locked rotor protection | When impurities enter the pipeline, the pump is blocked, the pump current suddenly increases, and the pump stops rotating. | |||
| 2 | Dry running protection | The water pump stops running at a low speed for 15min without circulating medium, and can be restarted to prevent the damage of the water pump caused by serious wear of parts. | |||
| 3 | Reverse connection of power supply | When the power polarity is reversed, the motor is self protected and the water pump does not start; The water pump can operate normally after the power polarity returns to normal | |||
| Recommended installation method | |||||
The installation angle is recommended, Other angles affect the discharge of water pump. |
|||||
| Faults and solutions | |||||
| Fault phenomenon | reason | solutions | |||
| 1 | Water pump doesn’t work | 1. The rotor is stuck due to foreign matters | Remove the foreign matters that cause the rotor to be stuck. | ||
| 2. The control board is damaged | Replace the water pump. | ||||
| 3. The power cord is not connected properly | Check whether the connector is well connected. | ||||
| 2 | Loud noise | 1. Impurities in the pump | Remove impurities. | ||
| 2. There is gas in the pump that cannot be discharged | Place the water outlet upward to ensure that there is no air in the liquid source. | ||||
| 3. There is no liquid in the pump, and the pump is dry ground. | Keep liquid in the pump | ||||
| Water pump repair and maintenance | |||||
| 1 | Check whether the connection between the water pump and the pipeline is tight. If it is loose, use the clamp wrench to tighten the clamp | ||||
| 2 | Check whether the screws at the flange plate of the pump body and the motor are fastened. If they are loose, fasten them with a cross screwdriver | ||||
| 3 | Check the fixation of the water pump and the vehicle body. If it is loose, tighten it with a wrench. | ||||
| 4 | Check the terminals in the connector for good contact | ||||
| 5 | Clean the dust and dirt on the external surface of the water pump regularly to ensure normal heat dissipation of the body. | ||||
| Precautions | |||||
| 1 | The water pump must be installed horizontally along the axis. The installation location should be as far away from the high temperature area as possible. It should be installed at a location with low temperature or good air flow. It should be as close to the radiator tank as possible to reduce the water inlet resistance of the water pump. The installation height should be more than 500mm from the ground and about 1/4 of the water tank height below the total height of the water tank. | ||||
| 2 | The water pump is not allowed to run continuously when the outlet valve is closed, causing the medium to vaporize inside the pump. When stopping the water pump, it should be noted that the inlet valve must not be closed before stopping the pump, which will cause sudden liquid cut-off in the pump. | ||||
| 3 | It is forbidden to use the pump for a long time without liquid. No liquid lubrication will cause the parts in the pump to be lack of lubricating medium, which will aggravate the wear and reduce the service life of the pump. | ||||
| 4 | The cooling pipeline shall be arranged with as few elbows as possible (elbows less than 90 ° are strictly prohibited at the water outlet) to reduce pipeline resistance and ensure smooth pipeline. | ||||
| 5 | When the water pump is used for the first time and used again after maintenance, it must be fully vented to make the water pump and suction pipe full of cooling liquid. | ||||
| 6 | It is strictly prohibited to use liquid with impurities and magnetic conductive particles larger than 0.35mm, otherwise the water pump will be stuck, worn and damaged. | ||||
| 7 | When using in low temperature environment, please ensure that the antifreeze will not freeze or become very viscous. | ||||
| 8 | If there is water stain on the connector pin, please clean the water stain before use. | ||||
| 9 | If it is not used for a long time, cover it with a dust cover to prevent dust from entering the water inlet and outlet. | ||||
| 10 | Please confirm that the connection is correct before powering on, otherwise faults may occur. | ||||
| 11 | The cooling medium shall meet the requirements of national standards. | ||||
Description
As the world continues to prioritize environmental sustainability, the adoption of electric vehicles, including buses, has gained significant momentum. As electric buses replace traditional diesel-powered buses, it is critical to ensure these vehicles operate efficiently and reliably. The 12V electric water pump is one of the key components for the smooth operation of electric buses. In this article, we will explore the importance of water pumps for electric buses, specifically automotive 12-volt water pumps, and understand their role in maintaining optimal performance in these environmentally friendly vehicles.
1. Understand the cooling system of electric buses:
Electric buses, like any other vehicle, require efficient cooling systems to maintain optimal temperatures of their components. Since most electric buses run on high-voltage batteries and electric motors, it's critical to prevent overheating, which can lead to reduced performance or even damage. This is where 12V electric water pumps for automotive applications come into play.
2. The significance of 12V electric water pump:
a) Cooling the battery pack: The electric bus battery pack will generate a lot of heat during operation. To ensure its service life, an efficient cooling system is crucial. The 12V electric water pump plays a vital role in circulating coolant in the battery pack, effectively dissipating excess heat and preventing any damage.
b) Cooling motor: Electric bus motors also generate heat during operation. Similar to battery packs, these motors require adequate cooling to prevent overheating. The automotive 12V water pump circulates coolant through the motor, maintaining its optimal temperature and ensuring smooth operation.
3. Advantages of 12V electric water pump in automotive applications:
a) Improved efficiency: Compared with traditional mechanical water pumps, 12V electric water pumps consume less power, making them an ideal choice for electric buses seeking to improve efficiency. By using electric pumps, electric buses can save energy, thereby extending their driving range and reducing electricity consumption.
b) Reliability and durability: Unlike mechanical water pumps, 12V electric water pumps for automotive applications have fewer moving parts, thus reducing wear and tear. They are also prone to failure and require minimal maintenance, ensuring increased reliability and longevity.
c) Enhanced control and monitoring: The 12V electric water pump can be integrated into the control system of the electric bus, allowing real-time monitoring of coolant flow and temperature. This feature supports proactive maintenance, ensuring early detection of problems and minimizing the risk of unexpected failures.
4. Overcoming the challenges of electric water pump integration:
Despite the many advantages of a 12V electric water pump, integrating it into an electric bus cooling system is not without its challenges. Compatibility with existing systems, optimizing power consumption and ensuring seamless integration with other components are key aspects that manufacturers need to address.
in conclusion:
The rapid development and adoption of electric buses brings various opportunities and challenges. One of the key factors for the successful operation of these environmentally friendly vehicles is the integration of efficient and reliable cooling systems. 12V electric water pumps for automotive applications play a vital role in maintaining optimal battery and motor temperatures, ensuring efficient operation and extending service life. As technology continues to develop, advances in water pump technology will undoubtedly help further improve the sustainability and efficiency of electric buses, ultimately shaping the future of public transportation.
