導(dǎo)致全自動(dòng)攪拌車發(fā)動(dòng)機(jī)水溫高的6個(gè)原因

來(lái)源:http://www.zvmc.cn 瀏覽:0發(fā)表時(shí)間:2023-04-17
全自動(dòng)攪拌車發(fā)動(dòng)機(jī)系統(tǒng)是一個(gè)整體,需要每個(gè)部件緊密配合才能滿足發(fā)動(dòng)機(jī)的工作需求;這些部件中只要有一個(gè)出現(xiàn)問(wèn)題,都會(huì)影響發(fā)動(dòng)機(jī)正常工作。發(fā)動(dòng)機(jī)水溫的正常情況下應(yīng)當(dāng)是在80°C~90°C之間,如果水溫經(jīng)常高于95°C或者開(kāi)鍋就應(yīng)該檢查故障了。那么是什么原因?qū)е铝怂疁剡^(guò)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?
日常保養(yǎng)要到位
Daily maintenance should be in place
水箱里的冷卻液低于低刻度線以下,這個(gè)就是日常保養(yǎng)工作不到位沒(méi)有注意到冷卻液的缺失。添加冷卻液規(guī)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.
留意保溫簾通風(fēng)情況
Pay attention to the ventilation of the insulation curtain
水箱上安裝的散熱扇皮帶松緊度不夠,打滑導(dǎo)致風(fēng)扇和水泵的轉(zhuǎn)速不夠,風(fēng)扇轉(zhuǎn)速不夠?qū)е滤涞睦滹L(fēng)流量太低,水泵的轉(zhuǎn)速不夠?qū)е吕鋮s液的循環(huán)速度太慢。在水箱前方裝有保溫簾的卡友,在水溫升高的時(shí)候沒(méi)有注意到打開(kāi)保溫簾通風(fēng)降溫。
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.
全自動(dòng)攪拌車廠家
水箱水管堵塞
Blocked water pipe in water tank
全自動(dòng)攪拌車廠家提醒,水箱水管堵塞導(dǎo)致水管截面變小,水循環(huán)效率降低,因?yàn)樗渖崴艿亩氯?,水管截面變小使發(fā)動(dòng)機(jī)內(nèi)進(jìn)入水箱上水管的水量遠(yuǎn)多于下水管進(jìn)入發(fā)動(dòng)機(jī)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.
結(jié)果就是經(jīng)冷卻過(guò)后的水都積壓在水箱的上水管,使上水管壓力增高,造成水箱泄水,泄水后水量減少致使發(fā)動(dòng)機(jī)過(guò)熱。
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.
節(jié)溫器是否失效
Is the thermostat ineffective
節(jié)溫器長(zhǎng)期使用后出現(xiàn)故障或者功能衰減使閥門(mén)的開(kāi)度變小,致使水循環(huán)緩慢甚中斷,進(jìn)而導(dǎo)致發(fā)動(dòng)機(jī)水溫過(guò)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.
判斷節(jié)溫器是否可以繼續(xù)使用的檢測(cè)標(biāo)準(zhǔn)為,把節(jié)溫器放在水里加熱檢查閥門(mén)開(kāi)始開(kāi)啟的溫度和完全開(kāi)啟的溫度以及閥門(mén)從開(kāi)啟完全開(kāi)啟的升程。閥門(mén)開(kāi)始開(kāi)啟的溫度一般為80°C左右,完全開(kāi)啟時(shí)的溫度一般為90°C左右,閥門(mén)工作的升程一般為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
在寒冷天氣如果沒(méi)有添加防凍液,那么全自動(dòng)攪拌車水泵里的水就容易結(jié)冰導(dǎo)致水泵葉輪不能轉(zhuǎn)動(dòng)。啟動(dòng)車輛時(shí),皮帶強(qiáng)行帶動(dòng)水泵轉(zhuǎn)動(dòng),就很容易造成水泵損壞。
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.
風(fēng)扇離合器故障
Fan clutch failure
現(xiàn)在路上跑的卡車包括攪拌車等專用車大部分都配備有風(fēng)扇離合器,風(fēng)扇離合器可以根據(jù)發(fā)動(dòng)機(jī)的溫度來(lái)調(diào)節(jié)風(fēng)扇的轉(zhuǎn)速,使發(fā)動(dòng)機(jī)持續(xù)在佳工作狀態(tài)下工作。當(dāng)風(fēng)扇離合器發(fā)生故障時(shí),就容易引起水溫過(guò)高,水箱開(kāi)鍋。
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.
