If there is a problem with the automatic feeding mixer, and the cause of the failure can not be found, it will have a bad impact on the direction booster pump, and more likely, it will be damaged.

自動(dòng)上料攪拌車轉(zhuǎn)向助力泵，我們通常把它叫做方向機(jī)助力泵，它是清障車轉(zhuǎn)向助力系統(tǒng)的動(dòng)力源，也是轉(zhuǎn)向系統(tǒng)的心臟部分。對(duì)于重型清障車來(lái)說(shuō)，由于機(jī)械式方向機(jī)，駕駛員操作勞動(dòng)強(qiáng)度大，所以液壓轉(zhuǎn)向系統(tǒng)就更為重要。

Automatic feeding mixer power steering pump, we usually call it steering power pump, it is the power source of the steering system of the wrecker, but also the heart of the steering system. For heavy-duty obstacle removal vehicles, due to the mechanical steering gear, the driver's labor intensity, so the hydraulic steering system is more important.

一般的葉片泵是由一個(gè)內(nèi)腔雙圓弧曲線的泵體帶槽轉(zhuǎn)子.葉片等零件組成。有的安裝在發(fā)動(dòng)機(jī)后端的飛輪殼上，也是靠正時(shí)齒輪驅(qū)動(dòng)。當(dāng)發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)時(shí)，帶動(dòng)助力泵轉(zhuǎn)子轉(zhuǎn)動(dòng)，葉片在離心力的作用下，沿葉片槽向外移動(dòng)，緊靠泵體的內(nèi)壁，在轉(zhuǎn)子轉(zhuǎn)動(dòng)過(guò)程中，由于葉片間封閉的容積不斷的增加和減小實(shí)現(xiàn)了吸油和壓油的過(guò)程。

The general vane pump is composed of a pump body with double circular arc curve and grooved rotor and blade. Some of them are installed on the flywheel housing at the rear end of the engine and are driven by timing gears. When the engine is running, it drives the rotor of the booster pump to rotate. Under the action of centrifugal force, the blade moves outward along the blade groove and is close to the inner wall of the pump body. In the process of rotor rotation, due to the continuous increase and decrease of the closed volume between the blades, the process of oil absorption and oil pressure is realized.

轉(zhuǎn)子每轉(zhuǎn)一周，完成吸油和壓油二次。在泵體內(nèi)還有閥以限制壓力。當(dāng)轉(zhuǎn)向系外部負(fù)荷增加，導(dǎo)致油壓升高到一定數(shù)值時(shí)，閥開啟卸掉負(fù)荷。泵體內(nèi)還安裝有節(jié)流閥和流量控制閥，以保證助力泵的排量基本上處于穩(wěn)定性。

Every rotation of the rotor, complete oil suction and oil pressure twice. There is also a relief valve in the pump body to limit the maximum pressure. When the external load of the steering system increases and the oil pressure rises to a certain value, the safety valve opens to unload the load. The throttle valve and flow control valve are also installed in the pump body to ensure that the displacement of the booster pump is basically stable.

方向機(jī)助力泵的使用與維護(hù)尤為重要，因此，必須做到以下幾點(diǎn)：

The use and maintenance of steering gear booster pump is particularly important. Therefore, the following points must be done:

一、在使用中如發(fā)現(xiàn)方向機(jī)助力泵滲漏，沖擊或有異常的噪音，應(yīng)及時(shí)檢查排除。

1、 If leakage, impact or abnormal noise are found in the use of the steering gear booster pump, timely check and eliminate.

二、自動(dòng)上料攪拌車運(yùn)行一段時(shí)間后，應(yīng)及時(shí)更換液壓油幾濾芯，尤其是新泵裝車后使用2500-3000應(yīng)更換液壓油。

2、 After the automatic feeding mixer runs for a period of time, several filter elements of hydraulic oil should be replaced in time, especially when the new pump is used 2500-3000 km after loading.

三、定期檢查儲(chǔ)油罐的油平面，不足應(yīng)及時(shí)補(bǔ)充清潔的液壓油，儲(chǔ)油罐內(nèi)的濾芯應(yīng)在保養(yǎng)時(shí)用酒精清洗干凈。

3、 Check the oil level of the oil tank regularly. If it is insufficient, clean hydraulic oil should be added in time. The filter element in the oil tank should be cleaned with alcohol during maintenance.

四、正確選擇液壓油是保證助力泵率，延長(zhǎng)壽命的關(guān)鍵。

4、 The correct selection of hydraulic oil is the key to ensure high efficiency and prolong service life of booster pump.

我們應(yīng)該如何進(jìn)行換油呢？方法如下：

How should we change the oil? The method is as follows:

支起前橋，使車輪離地。拆下儲(chǔ)油罐蓋，拆下回油管及方向機(jī)放油螺塞。啟動(dòng)發(fā)動(dòng)機(jī)高速運(yùn)轉(zhuǎn)10分鐘左右，使儲(chǔ)油罐，方向機(jī)助力泵，方向機(jī)內(nèi)的液壓油排出。發(fā)動(dòng)機(jī)熄火，左右轉(zhuǎn)動(dòng)方向盤極限位置，把殘余的液壓油全部排出。更換濾芯，加液壓油規(guī)定的高度，排凈液壓系統(tǒng)的空氣。

Support the front axle so that the wheels are off the ground. Remove the oil tank cover, oil return pipe and oil drain plug of steering gear. Start the engine to run at high speed for about 10 minutes, so that the oil tank, steering gear booster pump and hydraulic oil in the steering gear are discharged. Turn the steering wheel left and right to the limit position to drain the residual hydraulic oil. Replace the filter element, add hydraulic oil to the specified height, and exhaust the air in the hydraulic system.
