Hello, Hello, there are several reasons for the high water temperature:
1. Open the water tank cover with the water pump, start the engine and run it alternately between high and high rpm. low speed. At the same time, check whether the water in the water tank is. If there is obvious rolling phenomenon, the water pump can be considered normal. ?
2 Thermostat Remove the thermostat and check the thermostat opening temperature. Suspend the thermostat and thermometer in a container of water, then heat the container, observe the start temperature of the thermostat, continue heating, note the total opening temperature of the thermostat and check if these two temperatures are within a range reasonable. Finally, stop heating, wait for the water temperature to drop below 82°C, and check if the thermostat is in the closed position. Otherwise, the thermostat needs to be repairedre or replaced.
3 Water tank (including radiator) Check whether there is scale on the surface of the water tank and whether the cooling air duct and water flow channel water inside the water tank are smooth. If necessary, ask professionals to disassemble and clean it.
4 Fan Check whether the fan blades are damaged, severely deformed or installed backwards, and whether there is oscillation. If there are any, they will be immediately eliminated. ? 5 Fan belt Press the fan belt with your hand to check whether the tightness is normal. If the belt is loose, check whether the fan belt is slipping or not.
6. Air guide cooling system Water-cooled engines mainly use suction air cooling. The air on both sides of the water tank cannot produce convection. With the exception of the interconnection of condcooling air ducts of the water tank, other parts must be insulated. What cannot be ignored is that after many machines have been used for a period of time, the barrier materials have aged and fallen off seriously, resulting in the formation of ventilation channels around the water tank. water, which reduces airflow through the water tank and causes high temperatures. . In real maintenance, this situation is more common. ?
7. There is too much scale in the motor body. Check if there is too much scale in the motor housing and water channels. If so, they need to be cleaned. I hope my answer can be useful to you. If you have a problem with your car, ask the auto guru. Professional technicians from 4S stores can solve the problem within 10 minutes.
What are the reasons for the high water temperature of the forklift engineur?
Yes.
1. The vacuum belt can provide stable support: the line scan camera should scan on a stable plane to avoid shaking or movement that affects the scanning effect. The suction belt can be fixed on the surface of the scanning platform to fix the camera in place by suction, thereby providing stable support, thereby improving the accuracy and effect of scanning.
2. The vacuum belt can reduce the vibration and interference generated by the camera during the scanning process: the line scan camera will be affected by various factors during the scanning process, such as the texture of the scanning surface. and vibration of the camera itself, etc., resulting in deviation or distortion in the camera scanning results. The vacuum belt can reduce the friction between the camera and the surface of nscanning, absorb vibration and interference generated by the camera, reduce the influence of these factors, and improve the accuracy and effect of scanning.
1 Water pump: open the water tank cover, start the engine, run the engine alternately between high speed and low speed, and check the water in the water tank at the same time time.Is there any obvious turnover phenomenon? If yes, the water pump can be considered normal. ?
2 Thermostat Remove the thermostat and check the thermostat opening temperature. Suspend the thermostat and thermometer in a container of water, then heat the container, observe the start temperature of the thermostat, continue heating, note the total opening temperature of the thermostat and check if these two temperatures are within a range reasonable. Finally, stop heating, wait for the water temperature to drop below 82°C, and checki the thermostat is in the closed position. Otherwise, the thermostat must be repaired or replaced.
3 Water tank (including radiator) Check whether there is scale on the surface of the water tank and whether the cooling air duct and water flow channel water inside the water tank are smooth. If necessary, ask professionals to disassemble and clean it.
4 Fan Check whether the fan blades are damaged, seriously deformed or installed backwards, and whether there is oscillation, etc. If there are any, they will be immediately eliminated. ?
5 Fan belt Press the fan belt with your hand to check whether the tightness is normal. If the belt is loose, check whether the fan belt is slipping or not.
6 Air guide cooling system Water-cooled engines mainly use suction air cooling. Air on both sides of the tankwater cannot produce convection. Except for the interconnection of the water tank cooling air pipes, other parts should be insulated. What cannot be ignored is that after many machines have been used for a period of time, the barrier materials have aged and fallen off seriously, resulting in the formation of ventilation channels around the water tank. water, which reduces airflow through the water tank and causes high temperatures. . In real maintenance, this situation is more common. ?
7 The motor body has too much scale. Check the motor housing and water channels for excessive scale. If so, they need to be cleaned.
The second category has the following reasons:
1 Excessive wear of moving parts After excessive wear of moving parts such as cylinder liners and bearings, additional heat will be generated when the machineine. If these calories exceed a certain value, the water temperature will also be too high. When the cylinder liner is excessively worn, it is often accompanied by the following phenomena: ① Engine power is reduced ② Engine oil is burned ③ Exhaust gas emissions are excessive; Phenomena commonly associated with excessive bearing wear include: ① Oil temperature rises more quickly; ② The oil pressure drops significantly after the oil temperature increases; ③ There is a dull knocking sound; ?
2 Fuel delivery time is incorrect. If the fuel supply time is incorrect, the engine will be difficult to start, the power will drop and this will be accompanied by abnormal smoke exhaust. the supply time is too early or too late, there will be obvious consequences the sound of the cylinder knocking.
3 There is too little watercooling and too little engine oil. Check if the quantities of water and oil are normal and top up if they are insufficient. ?
4 Overload operation Check if the machine has been overloaded for a long time. If so, immediately switch it to normal operation. After a while, check if the water temperature is normal. ?
5 Insufficient air intake (1) Check whether the air filter is clogged; (2) Check whether the air filter inlet is blocked (3) Whether the turbocharger is damaged; the connection between the compressor and the engine air inlet is damaged. If this is the case, appropriate measures should be taken to resolve the problem.
