高溫季節是車輛事故頻發的季節，比如爆胎、自燃、發動機過熱等等，對于全自動攪拌車來說，比較容易出現散熱器故障，當你的攪拌車散熱器出現故障，檢查以下幾個部位，基本上就可以解決問題了。

High temperature season is a season of frequent vehicle accidents, such as tire blowout, spontaneous combustion, engine overheating, etc. for full-automatic mixer, radiator failure is relatively easy. When your mixer radiator fails, check the following parts, and basically solve the problem.

1.檢查保險開關：攪拌車是通過液壓傳動系統來驅動罐體的，液壓油散熱系統中容易出現故障的就是保險開關，因此在故障發生后，好及時檢查保險開關。

1. Check the safety switch: the mixer drives the tank body through the hydraulic transmission system. The safety switch is the one that is prone to failure in the hydraulic oil cooling system. Therefore, it is better to check the safety switch in time after the failure occurs.

2.檢查驅動風扇：電機是整個散熱系統中為關鍵的部件，散熱效果的好與壞，和電機的轉速及運行的平穩狀態有著直接的關系，它由連接車輛電瓶的電控盒直接供電，用電力驅動電機高速運轉，來帶走熱交換器當中的額熱量，給液壓油降溫。

2. Check the drive fan: the motor is the key component in the whole heat dissipation system. The good or bad heat dissipation effect has a direct relationship with the rotation speed and smooth operation of the motor. It is directly powered by the electric control box connected to the vehicle battery. It drives the motor to run at high speed with electricity to take away the heat in the heat exchanger and cool the hydraulic oil.

3.檢查熱交換器：攪拌車利用液壓油散熱器來進行降溫。熱交換器上裝有電機驅動風扇進行散熱，讓液壓油正常工作，上面的機械式指針通過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，剛開始出現的時候只需要拔掉上面的橡膠指針歸零，如果后面還出現讀書且拔掉橡膠塞之后還解決不了的話，就需要更換液壓油濾芯了。

3. Check the heat exchanger: the mixer uses the hydraulic oil radiator to cool down. The heat exchanger is equipped with a motor-driven fan to dissipate heat and make the hydraulic oil work normally. The mechanical pointer on the top detects the negative pressure in the pipeline. If there is a reading indicating that the hydraulic oil filter may be blocked, it is only necessary to pull out the rubber pointer on the top to zero at the beginning. If there is still reading and the problem cannot be solved after pulling out the rubber plug, it is necessary to replace the hydraulic oil filter element.

4.檢查熱傳感器：溫度傳感器位于熱交換器的進油管上，它的作用就是檢測液壓油的溫度，攪拌車散熱系統發生故障后，如果確認不是保險的問題，那就檢查溫度傳感器。

4. Check the heat sensor: the temperature sensor is located on the oil inlet pipe of the heat exchanger, and 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：散熱控制盒監控和接受溫度傳感其傳遞過來的信號，當溫度數據超過設定值后，自動接通散熱風扇的電路，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，需要及時更換，一般情況下，散熱器控制盒不容易損壞。

5. Check the radiator control box: the radiator control box monitors and receives the signals transmitted by the temperature sensor. When the temperature data exceeds the set value, it automatically switches on the circuit of the radiator fan to let the air circulate and reduce the temperature of the hydraulic oil. Therefore, after the radiator control box is damaged, the radiator system cannot 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的散熱系統，車輛一旦出現故障，耽誤卸料，混凝土很可能會在罐體內部凝固，那就麻煩了，所以要預防住，更多事項就來我們網站http://www.www.boy7up.cn咨詢了解吧！

In summer, attention should be paid to the heat dissipation system of the concrete mixer. Once the vehicle breaks down and delays unloading, the concrete is likely to solidify inside the tank body, which is troublesome. So we should prevent it.
