叉车水温过高简单的处理方法

来源:/ 日期:2022-08-23 发布人:hangong

叉车水温过高的原因是发动机水温的高低主要是和节温器是否正常工作、水泵能否建立足够的压力、冷却风扇能否达到标准转速有关。那如何来检查济南8040网站威尼斯水温不正常呢?
The reason for the high water temperature of the forklift is that the engine water temperature is mainly related to whether the thermostat works normally, whether the water pump can establish sufficient pressure, and whether the cooling fan can reach the standard speed. How to check that the water temperature of Jinan used forklift is abnormal?
冷却系统一般由冷却风扇、散热器、节温器等元件构成。冷却风扇往往由发动机直接带动,并且风扇转速与发动机转速一致,冷却水温的控制主要依靠节温器。节温器的检查可在车上进行,方法如下:
The cooling system is generally composed of cooling fan, radiator, thermostat and other components. The cooling fan is often driven directly by the engine, and the fan speed is consistent with the engine speed. The cooling water temperature is mainly controlled by the thermostat. The thermostat can be inspected on the vehicle by the following methods:
发动机起动后的检查:打开散热器加水口盖,若散热器内冷却水平静,则表明节温器工作正常,否则表示节温器工作失常。这是因为在水温低于70℃时,节温器膨胀筒处于收缩状态,主阀门关闭;当水温高于80℃时,膨胀筒膨胀,主阀门渐渐打开,散热器内循环水开始流动。
Inspection after the engine is started: open the radiator filler cap. If the cooling level in the radiator is static, it indicates that the thermostat works normally; otherwise, it indicates that the thermostat works abnormally. This is because when the water temperature is lower than 70 ℃, the expansion cylinder of the thermostat is in a contracted state and the main valve is closed; When the water temperature is higher than 80 ℃, the expansion cylinder expands, the main valve gradually opens, and the circulating water in the radiator begins to flow.

当水温表指示70℃以下时,散热器进水管处若有水流动,水温温热,则表示节温器主阀门关闭不严,使冷却水过早大循环。水泵是冷却水在冷却系统中不断循环的动力,影响水泵的因素有叶轮和皮带,叶轮松动冷却水就无法循环,导致水泵受损。皮带过大,导致水温过高,太小则会对水泵轴承、发电机轴承造成损伤。
When the water temperature gauge indicates below 70 ℃, if there is water flowing at the radiator inlet pipe and the water temperature is warm, it indicates that the main valve of the thermostat is not tightly closed, which makes the cooling water circulate too early. The water pump is the power for the continuous circulation of cooling water in the cooling system. The factors affecting the water pump include the impeller and the belt. If the impeller is loose, the cooling water cannot circulate, resulting in damage to the water pump. If the belt is too large, the water temperature will be too high; if it is too small, the water pump bearing and generator bearing will be damaged.
风扇风量的检测:可将一薄纸放于散热器前面,当发动机运转时,若纸能被吹开,则说明风量足够。叶片不能装反,并应保证风扇防护罩齐全有效。
Detection of fan air volume: a thin paper can be placed in front of the radiator. When the engine is running, if the paper can be blown off, the air volume is sufficient. The blades shall not be installed reversely, and the fan protective cover shall be complete and effective.
散热器方面,叉车的底盘较低,散热器置于车辆的尾部。粉尘很容易在散热器表面堆积,如果不及时清洗,就会严重影响散热效果。冷却水严禁使用“硬水”,以防止散热器中产生水垢,导致冷却水添加不足。
In terms of radiator, the chassis of the forklift is low, and the radiator is placed at the rear of the vehicle. Dust is easy to 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 prohibited to use "hard water" for cooling water to prevent scaling in the radiator, resulting in insufficient cooling water addition.
