导致全自动搅拌车发动机水温高的6个原因

来源:https://www.jfjiaobanche.com 浏览:0发表时间:2023-04-17
全自动搅拌车发动机系统是一个整体,需要每个部件紧密配合才能满足发动机的工作需求;这些部件中只要有一个出现问题,都会影响发动机正常工作。发动机水温的正常情况下应当是在80°C~90°C之间,如果水温经常高于95°C或者开锅就应该检查故障了。那么是什么原因导致了水温过高呢?
The engine system of a fully automatic mixer truck is a whole, and each component needs to be closely coordinated to meet the working requirements of the engine; Any problem with one of these components will affect the normal operation of the engine. Under normal circumstances, the engine water temperature should be between 80 ° C and 90 ° C. If the water temperature often exceeds 95 ° C or the boiler is turned on, the fault should be checked. So what is the reason for the high water temperature?
日常保养要到位
Daily maintenance should be in place
水箱里的冷却液低于低刻度线以下,这个就是日常保养工作不到位没有注意到冷却液的缺失。添加冷却液规定刻度即可。
The coolant in the water tank is below the low mark, which is due to inadequate daily maintenance work and failure to pay attention to the lack of coolant. Add coolant to the specified scale.
留意保温帘通风情况
Pay attention to the ventilation of the insulation curtain
水箱上安装的散热扇皮带松紧度不够,打滑导致风扇和水泵的转速不够,风扇转速不够导致水箱的冷风流量太低,水泵的转速不够导致冷却液的循环速度太慢。在水箱前方装有保温帘的卡友,在水温升高的时候没有注意到打开保温帘通风降温。
The tightness of the cooling fan belt installed on the water tank is insufficient, causing slipping, resulting in insufficient speed of the fan and water pump. Insufficient fan speed leads to too low cold air flow rate in the water tank, and insufficient speed of the water pump leads to too slow circulation speed of the coolant. The card friend who is equipped with an insulation curtain in front of the water tank did not notice opening the insulation curtain for ventilation and cooling when the water temperature increased.

水箱水管堵塞
Blocked water pipe in water tank
全自动搅拌车厂家提醒,水箱水管堵塞导致水管截面变小,水循环效率降低,因为水箱散热水管的堵塞,水管截面变小使发动机内进入水箱上水管的水量远多于下水管进入发动机的水量。
The manufacturer of the fully automatic mixing truck reminds that the blockage of the water tank pipe leads to a smaller section of the water pipe and a decrease in water circulation efficiency. Due to the blockage of the radiator pipe in the water tank, the smaller section of the water pipe causes the amount of water entering the upper water pipe of the water tank in the engine to be much more than the amount entering the engine from the lower water pipe.
结果就是经冷却过后的水都积压在水箱的上水管,使上水管压力增高,造成水箱泄水,泄水后水量减少致使发动机过热。
The result is that the cooled water accumulates in the upper water pipe of the water tank, increasing the pressure of the upper water pipe and causing the water tank to leak. After the leak, the amount of water decreases, causing the engine to overheat.
节温器是否失效
Is the thermostat ineffective
节温器长期使用后出现故障或者功能衰减使阀门的开度变小,致使水循环缓慢甚中断,进而导致发动机水温过高。
After long-term use, the thermostat malfunctions or its function decays, causing the valve opening to decrease, resulting in slow or even interrupted water circulation, and ultimately leading to high engine water temperature.
判断节温器是否可以继续使用的检测标准为,把节温器放在水里加热检查阀门开始开启的温度和完全开启的温度以及阀门从开启完全开启的升程。阀门开始开启的温度一般为80°C左右,完全开启时的温度一般为90°C左右,阀门工作的升程一般为7~10毫米。
The testing standard for determining whether the thermostat can continue to be used is to place it in water and heat it to check the temperature at which the valve starts to open and fully opens, as well as the lift of the valve from open to fully open. The temperature at which the valve starts to open is generally around 80 ° C, the temperature at which it fully opens is generally around 90 ° C, and the working lift of the valve is generally 7-10 millimeters.
水泵故障
Water pump malfunction
在寒冷天气如果没有添加防冻液,那么全自动搅拌车水泵里的水就容易结冰导致水泵叶轮不能转动。启动车辆时,皮带强行带动水泵转动,就很容易造成水泵损坏。
If antifreeze is not added in cold weather, the water in the water pump of the fully automatic mixer truck is prone to freezing, causing the water pump impeller to not rotate. When starting the vehicle, the belt forcefully drives the water pump to rotate, which can easily cause damage to the water pump.
风扇离合器故障
Fan clutch failure
现在路上跑的卡车包括搅拌车等专用车大部分都配备有风扇离合器,风扇离合器可以根据发动机的温度来调节风扇的转速,使发动机持续在佳工作状态下工作。当风扇离合器发生故障时,就容易引起水温过高,水箱开锅。
Most of the trucks running on the road now, including mixer trucks and other specialized vehicles, are equipped with a fan clutch. The fan clutch can adjust the fan speed according to the engine temperature, so that the engine can continue to work in good working condition. When the fan clutch malfunctions, it is easy to cause the water temperature to be too high and the water tank to boil.
