How to overhaul the water temperature of electric storage forklift

Electric storage forklifts often have high water temperatures. Many friends have called and consulted on this issue. In this regard, we will explain in detail the cooling system structure and working principle of electric storage forklifts. I hope that we can always touch the doubts in the hearts of everyone in the explanation process and solve the problems that everyone encounters in the process of using electric forklifts.(Electric storage forklift manufacturers)

Let's first explain to everyone from the structure of the cooling system. The cooling system is composed of cooling fan, radiator, thermostat and other components. The cooling fan is directly driven by the engine, and the rotation speed is consistent with the engine speed. The cooling water temperature is mainly adjusted by a thermostat.(Electric storage forklift manufacturers)

The characteristics of this structure are convenient to maintain and save costs, but the control effect on the cooling water temperature is not very satisfactory. The temperature of the water mainly depends on whether the thermostat works normally, the water pump can supply sufficient pressure, and whether the speed of the cooling fan meets the standard.(Electric storage forklift manufacturers)

Let's take a look at how to check the thermostat. During the start of the cold start of the electric storage forklift engine, there will be a significant temperature difference when the inlet and outlet pipes are touched by hand, and the temperature difference will be significantly reduced after a period of work. When the engine reaches normal operating temperature, there is no obvious sense of temperature difference. However, the accurate method is to remove the thermostat, place it in water, and gradually heat it. Check the valve opening temperature and valve lift.(Electric storage forklift manufacturers)

When inspecting the pump of an electric storage forklift, it is mainly to see if the pump can supply sufficient pressure. When adding cooling water, if the coolant level decreases significantly as the engine speed increases, this indicates that the pump is working properly. Conversely, the water pump and the impeller may come loose, and the cooling water cannot be circulated. Then check the cooling fan. Use your fingers to press the middle of the belt. The lower deflection should be 11-13mm. It is normal. When checking the air volume, place a thin paper in front of the radiator water tank. When the engine is running, the paper cannot be attached to the water tank. The fan blades cannot be reversed. The protective cover is complete and effective.(Electric storage forklift manufacturers)

The radiator located at the rear of the electric storage forklift should also be inspected. If the dust and impurities on the surface are not cleaned in time, the heat dissipation effect will be seriously affected, but the high-pressure water gun cannot be used because the tube wall of the radiator is thin, and high-pressure cleaning will wash the tube wall and affect the heat dissipation. In addition, do not use hard water. This is to avoid the formation of scale and insufficient cooling water.(Electric storage forklift manufacturers)
