The tank operation of the full-automatic feeding mixer is operated by hydraulic transmission. The hydraulic oil moves at a certain speed in the pipeline for a long time, which conflicts with the pipe wall. In addition to the resistance of various valves in the pipeline and the work of the oil pump, the hydraulic oil is compressed, which makes the hydraulic oil generate heat and the oil temperature rises. Hydraulic oil normal operation, there is a certain temperature is merit, but if beyond the temperature scale, not only will make the whole operation system unstable, but also will damage the seal and aggravate the oxidation and degeneration of hydraulic oil. The hydraulic oil heat dissipation system of small concrete mixer truck is generally composed of the following four parts, among which it is easy to have faults is used to maintain the stability of the whole circuit. Therefore, when presenting such problems, drivers of small concrete mixer should check whether it is stable and normal before troubleshooting other parts.

全自動(dòng)上料攪拌車的熱交換器相似水箱，液壓油流過來降溫。和發(fā)動(dòng)機(jī)散熱的原理相同，小型混凝土攪拌車運(yùn)用液壓油散熱器來進(jìn)行降溫。熱交換器（也能夠叫做散熱油箱）上裝的電機(jī)驅(qū)動(dòng)電扇進(jìn)行強(qiáng)制的散熱，讓液壓油保持在正常的作業(yè)規(guī)模。上面的機(jī)械式指針通過檢測(cè)管路傍邊的負(fù)壓，假如呈現(xiàn)讀數(shù)證明液壓油濾清器或許呈現(xiàn)阻塞，剛開始呈現(xiàn)的時(shí)分只需要拔掉上面的橡膠塞讓指針歸零，假如后邊還呈現(xiàn)讀數(shù)且拔掉橡膠塞之后還不了的話，就需要替換液壓油濾芯了。

The heat exchanger of the full-automatic feeding mixer is similar to the water tank, and the hydraulic oil flows to cool the temperature. With the same principle of engine heat dissipation, small concrete mixer truck uses hydraulic oil radiator to cool down. The heat exchanger (also known as the radiator tank) is equipped with a motor to drive the electric fan for forced heat dissipation, so that the hydraulic oil can be kept at normal operation scale. The mechanical pointer above detects the negative pressure at the side of the pipeline. If the reading shows that the hydraulic oil filter may be blocked, it is only necessary to pull out the rubber plug on the top to let the pointer return to zero at the beginning of the display. If the reading at the back still shows and the solution can not be solved after pulling out the rubber plug, the hydraulic oil filter element needs to be replaced.
             

全自動(dòng)上料攪拌車的電機(jī)驅(qū)動(dòng)電扇，帶走液壓油熱量。電機(jī)是整個(gè)散熱體系傍邊，然后注意要害的部件，散熱作用的好與壞，和電機(jī)的轉(zhuǎn)速以及作業(yè)的平穩(wěn)狀況有著直接的聯(lián)系。它由銜接車輛電瓶的電控盒直接供電，用電力驅(qū)動(dòng)電機(jī)高速作業(yè)，來帶走熱交換器傍邊的熱量，給液壓油降溫。

The electric fan driven by the motor of the fully automatic feeding mixer can take away the heat of hydraulic oil. The motor is the whole heat dissipation system side, and then pay attention to the key parts, the heat dissipation effect is good or bad, and the speed of the motor and the stability of the operation has a direct connection. It is directly powered by the electric control box which connects the vehicle battery, and uses the electric drive motor to work at high speed to take away the heat near the heat exchanger and cool the hydraulic oil.

小型混凝土攪拌車溫度傳感器，檢測(cè)液壓油溫度。安裝在熱交換器進(jìn)油管上的傳感器，用來檢測(cè)進(jìn)入熱交換器中液壓油的溫度，它是在掃除穩(wěn)妥毛病之后二個(gè)來掃除的毛病點(diǎn)。

Small concrete mixer temperature sensor to detect the temperature of hydraulic oil. The sensor installed on the oil inlet pipe of the heat exchanger is used to detect the temperature of the hydraulic oil entering the heat exchanger. It is used to remove the two fault points after clearing the safe fault.

小型混凝土攪拌車操控盒是大腦，不讓液壓油高溫。操控盒是整個(gè)散熱體系傍邊的大腦，相似于車輛的ECU，溫度傳感器傳遞過來的數(shù)據(jù)通過它的剖析，超越預(yù)訂的溫度值之后接通散熱電機(jī)的電路，讓電機(jī)作業(yè)來帶走液壓油中的溫度。它的上面裝有維護(hù)整個(gè)電路的穩(wěn)妥，讓操控盒不會(huì)容易損壞。

Small concrete mixer control box is the brain, not to let the hydraulic oil high temperature. The control box is the brain beside the whole cooling system, similar to the ECU of the vehicle. Through its analysis, the data transmitted by the temperature sensor exceeds the predetermined temperature value, and then the circuit of the heat dissipation motor is connected to let the motor work to take away the temperature in the hydraulic oil. It is installed on the top of the maintenance of the entire circuit, so that the control box will not be easy to damage.
