We all know that in summer, the water temperature of the car's water tank will become higher, and the same forklift water tank will have a high temperature phenomenon. So what are the reasons for the increase in the water temperature of the forklift? There are many reasons for the high water temperature: the temperature control switch, the pump, the water pipe are rusted, the backwater is not good and other factors will cause this phenomenon. , whether the cooling fan and radiator can meet the standard. How to check the forklift water temperature is not normal? Below, hifoune diesel forklift will share with you the common sense of forklift water tank maintenance.

1. Check after the engine is started: Open the radiator water filler cap, if the cooling level in the radiator is stable, it means that the thermostat is working normally, otherwise the thermostat is not working properly. This is because, when the water temperature is lower than 70 degrees, the expansion cylinder of the thermostat is in a contracted state, and the main valve is closed, and when the water temperature is higher than 80 degrees, the expansion cylinder expands. The main valve is gradually opened, and the circulating water in the radiator begins to flow. When the water temperature gauge indicates below 70 degrees, if there is water flowing at the water inlet pipe of the radiator and the water temperature is warm, it means that the main valve of the thermostat is not closed tightly, causing the cooling water to circulate prematurely.
2. Check after the water temperature rises: At the beginning of the engine operation, the water temperature rises rapidly. When the water temperature gauge indicates 80 degrees, the heating rate slows down, indicating that the thermostat works normally. On the contrary, if the water temperature keeps rising rapidly, When the internal pressure reaches a certain level, the boiling water suddenly overflows, indicating that the main valve is stuck and suddenly opens. When the water temperature gauge indicates 70-80 degrees, open the radiator cover and the radiator drain switch, and feel the water temperature by hand. If both are hot, it means that the thermostat is working normally. There is no or very little water flowing out of the water pipe. It means that the main valve of the thermostat cannot be opened.
water pump
The water pump is the driving force for the continuous circulation of cooling water in the cooling system. The factors affecting the water pump are the impeller and the belt. If the impeller is loosened, the cooling water cannot circulate, which will cause the water pump to be damaged. Bearings, generator bearings cause damage.
fan
For the detection of fan air volume, a thin piece of paper can be placed in front of the radiator. When the engine is running, if the paper can be blown open, it means that the air volume is sufficient. This is different from the inward suction of the car fan with the front engine, and the blades cannot Install it in reverse, and ensure that the fan cover is complete and effective.
heat sink
Because the chassis of the forklift is low and the radiator is placed at the rear of the vehicle, dust can easily accumulate on the surface of the radiator. If it is not cleaned in time, it will seriously affect the heat dissipation effect. It is strictly forbidden to use "hard water" for cooling water. To prevent scale in the radiator, resulting in insufficient cooling water.

Therefore, when you use the forklift to work, you should always pay attention to whether the water tank has high temperature and other adverse phenomena, and if there is a problem, you should contact the local dealer in time to prevent the micro and prevent the development of the forklift, so that your forklift is always in good condition!
