As shown in the figure:
In daily work, the generator set having no output voltage is also a relatively common fault. There are several reasons for generator failure:
1. A rectifier failure will not only result in no output voltage from the generator, but also no display of the output frequency. Scientific and technological articles, diesel generator. At this point, the rectifier assembly must be replaced to quickly eliminate the fault. It should be noted that you must choose a matching model.
2. When the generator coil is burned out, there will be obvious glue smell. Use a multimeter to check that the resistance of the winding terminal is zero (the winding has been sintered and caused a short circuit) or that the resistance is infinite (the winding has been burned. At this time, the winding of the coil needs to be repaired or). replacedor the generator must be replaced directly.
3. If the output voltmeter indicates that the voltage is normal, but the electrical equipment is not powered, the output switch of the Dongguan generator may be defective. After replacing the switch, the problem may occur. be eliminated.
Detailed information:
The piston operates under conditions of high temperature, high pressure, high speed and poor lubrication. The piston is in direct contact with high temperature gas, and the instantaneous temperature can reach more than 2500K. Therefore, it is heated greatly and the heat dissipation conditions are very poor. Therefore, the piston temperature is very high during operation. , with the peak reaching 600 ~ 700K, and the temperature distribution is veryuneven;
The top of the piston is subjected to significant gas pressure, especially the maximum pressure in the power stroke. is as high as 3~5 MPa for gasoline engines and 6~9 MPa for diesel engines. This causes the piston to impact and bear the effect of side pressure;
The piston reciprocates in the cylinder at a very high speed. (8 ~ 12 m/s), and the speed is constantly changing, which generates a large inertia force and subjects the piston to a large additional load. When the piston works under such harsh conditions, it will deform and accelerate its wear. It will also generate additional load and thermal stress, and it will also be subject to chemical corrosion by the gas.

Where is the tricycle water tank valve?
Add fluid cooling.
OpenRemove the water tank cover when the machine is cold and check the liquid level inside the water tank. If the liquid level is lower than the low liquid level warning line marked on the water tank, you should add an appropriate amount of pure liquid to the water tank. In winter, it is necessary to mix and add water proportionally to prevent the water in the water tank and the body from freezing and cracking the body and the water tank. The function of antifreeze is to reduce the freezing temperature of water in the body. water reservoir. Generally, anti-rust liquid is added to the water tank in summer and anti-freeze liquid is added to the water tank in winter.
In the water tank, you can add water but the effect is not very good. Adding antifreeze or the like will have a better cooling effect.
TricycleThe switchfor draining water from the water tank is located next to the large gear, under the generator. You can check the starter side and bottom of the body as well as the fuel injection pump side of the body.
In the first step, first use warm water at 70 ~ 80°C to water the tank, water pump and engine drain cock, then unscrew the two drain cocks. draining the water tank and body. In the second step, gradually increase the water temperature and continue pouring to drain the water from the drain outlet. At this point you can add boiling water to the water tank. until the discharged water reaches temperature.
The third step is to observe whether there are frost cracks and water leaks in the water tank and the machine body (the body is usually frozen and cracked in the very cold northern regions). no problem on the surface, itcontinue the inspection. The fourth step is to start the engine and run it at low speed, and observe whether there is a large amount of white smoke in the exhaust. If yes, it means that the cylinder head is frozen and cracked and the water channel is seeping into the cylinder. Otherwise, stop and wait a few hours or more (be careful to avoid refreezing).
A three-wheeler is a type of truck with a panel structure in the cargo area and three wheels. The power source can be a motor or an electric motor, mainly used to transport goods. Tricycles without a cabin whose empty weight exceeds 400 kg and tricycles with a cabin whose empty weight exceeds 600 kg are low-speed vehicle registration plates, and those that do not exceed this range are low-speed vehicle registration plates. motorcycle registration.
