1. Check the safety switch:
攪拌車(chē)是通過(guò)液壓傳動(dòng)系統來(lái)驅動(dòng)罐體的，液壓油散熱系統中容易出現故障的就是保險開(kāi)關(guān)，因此在故障發(fā)生后，時(shí)間檢查保險開(kāi)關(guān)。
Mixer is driven by hydraulic transmission system, the most prone to failure in the hydraulic oil cooling system is the safety switch, so after the failure, it is best to check the safety switch at the first time.
2、檢查驅動(dòng)風(fēng)扇：
2. Check the drive fan:
電機是整個(gè)散熱系統中為關(guān)鍵的部件，散熱效果的好與壞，和電機的轉速及運行的平穩狀態(tài)有著(zhù)直接的關(guān)系，它由連接車(chē)輛電瓶的電控盒直接供電，用電力驅動(dòng)電機高速運轉，來(lái)帶走熱交換器當中的額熱量，給液壓油降溫。
The motor is the most critical component in the whole heat dissipation system. The good or bad heat dissipation effect is directly related to the speed of the motor and the stable running state. It is directly powered by the electric control box connected to the vehicle battery, and uses the electric power to drive the motor to run at high speed to take away the amount of heat from the heat exchanger and cool the hydraulic oil.
3、檢查熱交換器：
3. Check the heat exchanger:
攪拌車(chē)利用液壓油散熱器來(lái)進(jìn)行降溫。熱交換器上裝有電機驅動(dòng)風(fēng)扇進(jìn)行散熱，讓液壓油正常工作，上面的機械式指針通過(guò)檢測管路當中的負壓，如果出現讀數證明液壓油濾清器可能出現堵塞，剛開(kāi)始出現的時(shí)候只需要拔掉上面的橡膠指針歸零，如果后面還出現讀書(shū)且拔掉橡膠塞之后還不了的話(huà)，就需要更換液壓油濾芯了。
Mixer truck uses hydraulic oil radiator to cool down. The heat exchanger is equipped with a motor-driven fan to dissipate heat, so that the hydraulic oil can work normally. The mechanical pointer on the top detects the negative pressure in the pipeline. If the reading indicates that the hydraulic oil filter may be blocked, just pull out the rubber pointer to zero at the beginning. If there is still a reading behind and the problem can not be solved after pulling out the rubber plug, The hydraulic oil filter element needs to be replaced.
4、檢查熱傳感器：
4. Check the thermal sensor:
溫度傳感器位于熱交換器的進(jìn)油管上，它的作用就是檢測液壓油的溫度，攪拌車(chē)散熱系統發(fā)生故障后，如果確認不是保險的問(wèn)題，那就檢查溫度傳感器。
The temperature sensor is located on the oil inlet pipe of the heat exchanger. Its function is to detect the temperature of the hydraulic oil. After the heat dissipation system of the mixer fails, if it is confirmed that it is not the insurance problem, check the temperature sensor.

5、檢查散熱器控制盒：
5. Check the radiator control box:
散熱控制盒監控和接受溫度傳感其傳遞過(guò)來(lái)的信號，當溫度數據超過(guò)設定值后，自動(dòng)接通散熱風(fēng)扇的電路，讓空氣流通降低液壓油的溫度，因此散熱控制盒損壞后，散熱系統就不能正常工作，需要及時(shí)更換，一般情況下，散熱器控制盒不容易損壞。
The cooling control box monitors and receives the signal from the temperature sensor. When the temperature data exceeds the set value, the circuit of the cooling fan is automatically connected to let the air flow and reduce the temperature of the hydraulic oil. Therefore, after the cooling control box is damaged, the cooling system can not work normally and needs to be replaced in time. Generally, the radiator control box is not easy to be damaged.

夏季要注意混凝土攪拌車(chē)的散熱系統，車(chē)輛一旦出現故障，耽誤卸料，混凝土很可能會(huì )在罐體內部凝固，那就麻煩了。
In summer, we should pay attention to the heat dissipation system of concrete mixer. Once the vehicle fails and the discharge is delayed, the concrete is likely to solidify inside the tank, which is troublesome.
