1, automatic exhaust return pipe.
As long as the return pipe does not block the smooth flow of water, there is no need to manually exhaust; There are two water pipes on the kettle of this car, one is to feed the engine, and the other is to the return pipe at the water tank or cylinder head.
It should be noted that don't screw on the lid immediately after adding enough water to start the engine. Only when the tap water in the return pipe continuously flows can the lid be screwed on. If the lid is screwed on in advance, the air in return pipe will not be discharged, and the water in the system will not circulate, which is prone to high temperature.
2. Don't bring back the water pipe.
There is only one water pipe on the kettle, so this car must be manually vented, otherwise how much antifreeze can be transferred out; Pay attention to the correct position of exhaust, otherwise the air exhaust will not be complete.
3. Water pipe connection of water-cooled motorcycle engine
There is no water in the motorcycle water tank.
1. Where can I add water to a water-cooled motorcycle? Under the front faucet, there is a water filler cap next to the radiator above the front wheel side.
2. The water-cooled engine has special cooling water, and it is not ordinary tap water.
3. Water-cooled motorcycle relies on water flow to cool the engine, and there is a water tank outside the engine. The function of the water tank is to circulate the hot water inside the engine back to the engine after being cooled by wind, so that the engine will not lose its working ability due to excessive temperature.
1. The water-cooled radiator has a water inlet and a water outlet, and there are many waterways inside the radiator, which can give full play to the advantages of water cooling and take away more heat. This is the basic principle of water-cooled radiator.
2. From the installation mode of water cooling, it can be divided into built-in water cooling and external water cooling. For built-in water cooling, it is mainly composed of radiator, water pipe, water pump and enough water source, which determines that most water cooling systems are "heavy" and need enough space inside the chassis.
3. As for the external water-cooled radiator, its cooling water tank, water pump and other working elements are arranged outside the chassis, which not only reduces the space occupation in the chassis, but also obtains better cooling effect.
4. Water-cooled motorcycle water pipe device
Installation and maintenance method of water pump for water-cooled tricycle
1. The water-cooled tricycle water exchange pump is located under the air grille assembly, near the booster pump.
2. The pump is also driven by the motor, so the rotation speed of the pump is directly related to the rotation speed of the motor. The calculation formula of motor speed is: n = 60f/p.
3. Where n is the synchronous speed of the motor, f is the power frequency, and p is the number of motor poles.
4. The shaft of the pump is directly connected with the motor shaft, and the rotating speed of the pump = the rotating speed of the motor.
5. The pump and motor are connected by a belt. Speed of pump = speed of motor * diameter of motor wheel ÷ diameter of motor wheel of pump.
5. Connection Diagram of Water-cooled Piping of Motorcycle
Does this engine you bought have an auxiliary water tank? If not, the water outlet on the left side of the engine is connected to the upper water inlet of the water cooler, and the lower water outlet of the water cooler is connected to the water inlet on the right side of the engine.
6. How to connect the water tank pipes of tricycles?
1, the engine cooling system must be carefully cleaned before filling antifreeze. This is because detergent and cleaning agent are added to the antifreeze. If the engine cooling system is not carefully cleaned before use, the original scale in the engine cooling system will fall off after contacting the antifreeze, making the antifreeze turbid, sticky and even discolored and smelly. In severe cases, it will block water pipes and waterways or precipitate at the elbow at the lower part of the water tank, resulting in poor heat dissipation and inability to circulate antifreeze, resulting in excessive engine temperature. In order to prevent these phenomena, before adding antifreeze, the water tank should be soaked in 10% caustic soda solution for one hour, and then the flushing liquid should be discharged, and then washed repeatedly with softened water for 2-3 times to remove the scale accumulated in the engine cooling system. Only after washing can antifreeze be added.
2. Check whether there is any leakage in the engine cooling system before filling antifreeze, and eliminate it in time before using antifreeze.
3. It is forbidden to directly add antifreeze mother liquor. Some drivers and maintenance workers think that the purer the antifreeze, the better, and the higher the concentration of ethylene glycol. If the freezing point of antifreeze is not met, some unexpected phenomena will appear, such as deterioration of antifreeze, high concentration and density, increased viscosity at low temperature and high engine temperature. Therefore, when using antifreeze mother liquor, it must be prepared as required, and direct use is prohibited.
4, antifreeze in use to implement regular inspection. The validity period of antifreeze is usually 4 years, so there is continuity in use. In order to reduce waste, do not replace antifreeze after filling. But the antifreeze in use should be checked regularly. Antifreeze can be checked once a year in combination with seasonal maintenance. The inspection contents shall include freezing point inspection and specific gravity inspection. At the same time, the antifreeze in use should be visually inspected. If it is found that the specific gravity increases, the antifreeze thickens, the freezing point rises, and the antifreeze becomes turbid, deteriorated, smelly and blistered, it should be replaced in time.
5, antifreeze produced by different manufacturers can't be mixed. Mixing easily corrodes the engine and water tank.
6. Avoid using natural water instead of antifreeze in summer, because antifreeze also has antiseptic effect. If natural water is used instead of antifreeze, it will accelerate the corrosion of water tank, cylinder and other parts and produce scale, resulting in poor heat dissipation of the engine, leading to an increase in temperature and shortening the service life of the engine.
7. If ordinary natural water is added for special reasons, when replacing antifreeze, it is necessary to run the engine at idle speed after starting, so as to ensure that all the natural water stored under the drain pipe of the engine is discharged.
7. How to take over the tricycle water cooling?
Three yellow connecting coils, black switch, positive electricity, green grounding and red battery.
8. Waterway map of water-cooled three-wheeled motorcycle
Generally, the pipe or small hole leaking downward from the small water pump is blocked to see if there is too much dust or foreign matter, which causes the pumped water not to flow back in time and overflow. Another possibility is that there is a crack in the equipment shell, which leads to water leakage.
The water tank may be broken,
One: put some paper towels at each joint and try to completely wrap the joint.
Two: after the paper towels are put away, let the pump run alone and let the whole waterway run.
Three: carefully observe whether each paper towel is wet. If there is water leakage, immediately turn off the power supply of the water pump and drain the water completely (the drain valve is also a necessity for water cooling).
Four: If there is no water leakage, it can't be turned on directly. At this time, you should keep the channel running.
9. How to connect the water pipes of motorcycle water-cooled engine?
If the water pipe of the motorcycle leaks from the water-cooled engine, check whether the coolant leaks. If it is leaking, check whether the water tank, water pipe, water seal and water pump are damaged or leaking.
It is normal if there is water coming out from the bottom or tail of the exhaust pipe. After burning gasoline, a small amount of water will be produced, and the discharged hot gas will condense into water when it is cold. This water will be discharged from the drain hole or tail of the exhaust pipe, which is normal.
10. How to connect the motorcycle water heating and cooling air duct?
How to connect the water pipe of the heater?
Connect the water inlet and outlet pipes on the heater, because water flows through the heater water tank through the engine. There is a water inlet valve or a water outlet valve beside the hot air tank to circulate water.
