叉车水温异常该怎么检查?有什么特征吗?为了后续更好更顺利的使用叉车,有关问题要提前了解到,下面济南叉车租赁人员为您分析:
How to check if the water temperature of the forklift is abnormal? What are the characteristics? In order to use forklifts better and smoothly in the future, it is important to understand the relevant issues in advance. Below is an analysis by the Jinan forklift rental personnel:
(1)发动机起动后检查:打开散热器喷嘴盖。如果散热器中的冷却液液位仍在,则表示节温器工作正常,否则表示节温器工作不正常。
(1) Check after starting the engine: Open the radiator nozzle cover. If the coolant level in the radiator is still high, it indicates that the thermostat is operating normally, otherwise it indicates that the thermostat is not operating properly.
(2)水温升高后检查:发动机运转初期水温达到数千度,水温表显示80度时,加热速度减慢,说明节温器工作正常。相反,如果水温持续上升,当内部压力达到一定水平时,沸水突然溢出,说明主阀卡住,突然打开。
(2) Inspection after the water temperature rises: During the initial stage of engine operation, the water temperature reaches thousands of degrees, and when the water temperature gauge displays 80 degrees, the heating speed slows down, indicating that the thermostat is operating normally. On the contrary, if the water temperature continues to rise rapidly, when the internal pressure reaches a certain level, the boiling water suddenly overflows, indicating that the main valve is stuck and suddenly opens.
(3)水温低于70℃时,节温器膨胀管处于收缩状态,主阀关闭;水温高于80℃时,膨胀管膨胀,主阀逐渐打开,散热器内循环水开始流动。
(3) When the water temperature is lower than 70 ℃, the expansion pipe of the thermostat is in a retracted state and the main valve is closed; When the water temperature is higher than 80 ℃, the expansion pipe expands, the main valve gradually opens, and the circulating water in the radiator begins to flow.
(4)当温度计显示70-80℃时,打开散热器盖和散热器放水开关,用手感觉水温。如果两只手都热,恒温器就会正常工作。如果散热器进水温度低,散热器上腔进水管无水或少水,则无法打开节温器主阀。
(4) When the thermometer displays 70-80 ℃, open the radiator cap and radiator drain switch, and feel the water temperature with your hands. If both hands are hot, the thermostat will work properly. If the water inlet temperature of the radiator is low, and there is no or little water in the water inlet pipe of the upper chamber of the radiator, the main valve of the thermostat cannot be opened.

(5)当温度计低于70℃时,如果散热器进水管内有水流,水温高,使用时温度计的主阀关不严,使冷却水过快过大。冷却系统一般由冷却风扇、散热器、节温器等部件组成。冷却风扇通常由发动机直接驱动,风扇转速与发动机转速相同。因此,冷却水温度的控制主要依靠恒温器。
(5) When the thermometer is below 70 ℃, if there is water flow in the radiator inlet pipe and the water temperature is high, the main valve of the thermometer is not tightly closed during use, resulting in excessive cooling water. The cooling system generally consists of cooling fans, radiators, thermostats, and other components. The cooling fan is usually directly driven by the engine, and the fan speed is the same as the engine speed. Therefore, the control of cooling water temperature mainly relies on thermostats.
此外要注意,炎热的夏季,叉车水箱会产生高温,不仅影响施工进度,还会对机器造成损坏。造成水温高的原因有很多,如温控开关、水泵、风机、水管生锈、回水不畅等因素都会造成这种结瘤。有关预防方式就来咨询我们http://www.jnhgjx.net吧!
In addition, it should be noted that in hot summer, the forklift water tank will generate high temperatures, which not only affects the construction progress, but also causes damage to the machine. There are many reasons for high water temperature, such as temperature control switches, water pumps, fans, rust on water pipes, and poor return water.
