One of his former colleagues recently called to say that his cooling fan had broken down, affecting operations. I was asked why. After asking about the fault and his solution, I suspect that the fault was burned by the insurance. After replacing the new insurance, the problem was solved. Today Xiaobian will talk about the hydraulic oil cooling system of the cement mixer with us.

　　坦克運行的水泥攪拌機是由液壓傳動,液壓油在很長一段時間內(nèi)以一定速度在管道流動,與管子的壁摩擦,除了管道在各種閥門阻力和油泵的工作,壓縮液壓油,液壓油會產(chǎn)生熱量,油溫上升。液壓油工作正常，一定的溫度是一件好事，但如果溫度范圍太大，不僅會使整個工作系統(tǒng)不穩(wěn)定，還會損壞油封，加劇液壓油氧化變質。

　　The tank operated cement mixer is driven by hydraulic pressure. The hydraulic oil flows in the pipeline at a certain speed for a long time, and rubs against the wall of the pipeline. In addition to the pipeline resistance in various valves and the work of the oil pump, the hydraulic oil will generate heat and the oil temperature will rise by compressing the hydraulic oil. If the hydraulic oil works normally, a certain temperature is a good thing, but if the temperature range is too large, it will not only make the whole working system unstable, but also damage the oil seal, aggravating the oxidation and deterioration of the hydraulic oil.

　　自上料混凝土攪拌罐車液壓油冷卻系統(tǒng)一般由下列四個部分組成,其中容易失敗是保護整個電路的保險,所以你打開自上料混凝土攪拌罐車,朋友這樣的問題的時候,次檢查是否正常的保險,然后其他部分的故障診斷。

　　The hydraulic oil cooling system of the concrete mixer is generally composed of the following four parts, of which the most likely failure is to protect the entire circuit, so when you open the concrete mixer, friends and other problems, check whether the insurance is normal for the first time, and then the fault diagnosis of other parts.

　　熱交換器就像一個液壓油箱，來冷卻它

　　The heat exchanger is like a hydraulic tank to cool it

　　就像發(fā)動機散熱一樣，全自動自上料攪拌車使用液壓油散熱器冷卻。熱交換器(又稱散熱箱)裝有電機驅動的風扇，強制散熱，使液壓油保持在正常工作范圍內(nèi)。

　　Just as the engine heats, the concrete mixer is cooled by a hydraulic oil radiator. The heat exchanger (also known as heat sink) is equipped with a fan driven by a motor, which forces heat dissipation to keep the hydraulic oil within the normal working range.

　　機械指針通過檢測管道的負壓,證明液壓油過濾器堵塞可能發(fā)生如果有讀數(shù),起初只需要刪除指針為零的橡皮塞,如果仍然出現(xiàn)后閱讀和把橡皮塞仍解決不了需要更換液壓油過濾器。

　　By detecting the negative pressure of the pipeline, the mechanical pointer proves that the hydraulic oil filter may be blocked. If there is a reading, at first only the rubber plug with zero pointer needs to be deleted. If there is still a reading and the rubber plug still cannot be solved, the hydraulic oil filter needs to be replaced.

　　馬達驅動的風扇帶走了液壓油的熱量

　　The fan driven by the motor takes away the heat of the hydraulic oil

　　電機是整個冷卻系統(tǒng)中重要的部分。冷卻效果的好壞直接關系到電機的轉速和運行狀態(tài)的好壞。它直接由一個與汽車電池相連的電箱供電，這個電箱驅動一個電機高速運轉，將熱量從熱交換器中帶走，并冷卻液壓液。

　　The motor is the most important part of the whole cooling system. The cooling effect is directly related to the speed and running state of the motor. It is powered directly by an electric box connected to the car battery, which drives a motor to run at high speed, takes heat away from the heat exchanger and cools the hydraulic fluid.

　　溫度傳感器檢測液壓油的溫度

　　Temperature sensor detects the temperature of hydraulic oil

　　在換熱器進水管上安裝傳感器，檢測進入換熱器的液壓油的溫度。

　　A sensor is installed on the water inlet pipe of the heat exchanger to detect the temperature of the hydraulic oil entering the heat exchanger.

　　控制箱是控制液壓油不受熱的大腦

　　The control box is the brain that controls the hydraulic oil not to be heated

　　控制箱是整個冷卻系統(tǒng)的大腦，類似于車輛的ECU。對溫度傳感器傳遞的數(shù)據(jù)進行分析。超過溫度值后，連接冷卻電機回路，運行電機帶走液壓油中的溫度。它的頂部有保險，以保護整個電路，使控制箱不容易損壞。

　　The control box is the brain of the whole cooling system, similar to the ECU of the vehicle. Analyze the data transmitted by the temperature sensor. After the temperature value is exceeded, connect the cooling motor circuit, and run the motor to take away the temperature in the hydraulic oil. It has a safety cover on the top to protect the whole circuit, so that the control box is not easy to damage.

　　好了，說一下它的原理，冷卻系統(tǒng)故障后電機不運行，經(jīng)濟、省時的故障排除順序請按以下順序檢查保險——更換溫度傳感器——更換電機——更換控制箱

　　Well, let's talk about its principle. After the cooling system fails, the motor does not run. For the most economical and time-saving troubleshooting sequence, please check the fuse in the following order - replace the temperature sensor - replace the motor - replace the control box
