How to repair the steering wheel power steering pump of automatic feeding mixer?

如果自動(dòng)上料攪拌車存在問題，而無法找到故障原因，則方向增壓泵將受到不利影響，并且更有可能造成損壞。

If there is a problem with the automatic charging mixer and the cause of the failure cannot be found, the directional booster pump will be adversely affected and more likely to be damaged.

自動(dòng)上料攪拌車轉(zhuǎn)向助力泵，通常稱為動(dòng)力轉(zhuǎn)向泵，是轉(zhuǎn)向助力系統(tǒng)和轉(zhuǎn)向系統(tǒng)的核心。對(duì)于重型清障車，由于機(jī)械轉(zhuǎn)向力和駕駛員的勞動(dòng)強(qiáng)度，液壓轉(zhuǎn)向系統(tǒng)變得更加重要。

The power steering pump of automatic feeding mixer, usually called power steering pump, is the core of power steering system and steering system. For heavy-duty wrecker, hydraulic steering system becomes more important because of mechanical steering force and driver's labor intensity.

通用葉片泵由在內(nèi)部腔體中具有雙曲線的泵體，帶槽轉(zhuǎn)子和葉片組成。其中一些安裝在發(fā)動(dòng)機(jī)后部的飛輪殼上，并由正時(shí)齒輪驅(qū)動(dòng)。當(dāng)發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)時(shí)，增壓泵的轉(zhuǎn)子被驅(qū)動(dòng)旋轉(zhuǎn)，葉片在離心力的作用下沿著葉片槽向外移動(dòng)，在轉(zhuǎn)子旋轉(zhuǎn)過程中緊靠泵體的內(nèi)壁，并在葉片之間大于封閉空間的體積不斷增加。實(shí)現(xiàn)了吸油和液壓過程。轉(zhuǎn)子每旋轉(zhuǎn)一圈，吸油量和油壓就完成兩次。泵體還具有閥以限制壓力。當(dāng)轉(zhuǎn)向系統(tǒng)上的外部負(fù)載增加并且液壓壓力上升到一定值時(shí)，閥將打開，并且負(fù)載將被移除。節(jié)流閥和流量控制閥也安裝在泵體內(nèi)，因此增壓泵的容量幾乎恒定。

The general vane pump consists of a pump body with hyperbola in the inner cavity, a grooved rotor and blades. Some of them are mounted on the flywheel housing at the rear of the engine and are driven by timing gears. When the engine is running, the rotor of the booster pump is driven to rotate, and the blades move outward along the blade slot under the action of centrifugal force. During the rotor rotation, it is close to the inner wall of the pump body, and the volume between the blades larger than the closed space increases continuously. The oil absorption and hydraulic process are realized. Every time the rotor rotates, the oil absorption and oil pressure are completed twice. The pump body also has a safety valve to limit the pressure. When the external load on the steering system increases and the hydraulic pressure rises to a certain value, the relief valve will open and the load will be removed. Throttle valve and flow control valve are also installed in the pump body, so the capacity of booster pump is almost constant.

由于轉(zhuǎn)向助力泵的使用和維護(hù)尤為重要，因此必須執(zhí)行以下操作：

Since the use and maintenance of the power steering pump is particularly important, the following operations must be carried out:

1.在使用過程中，如果轉(zhuǎn)向泵助力器泄漏，震動(dòng)或發(fā)出異常聲音，則有必要對(duì)其進(jìn)行檢查并逐步。

1. In the process of use, if the steering pump booster leaks, vibrates or makes abnormal sound, it is necessary to check and gradually eliminate it.

2.自動(dòng)上料攪拌車工作一段時(shí)間后，應(yīng)及時(shí)更換液壓油濾清器，特別是在安裝新泵后，在2500-3000 km之后應(yīng)更換液壓油。

2. After the automatic feeding mixer works for a period of time, the hydraulic oil filter should be replaced in time, especially after the installation of a new pump, the hydraulic oil should be replaced after 2500-3000 km.

3.定期檢查儲(chǔ)油罐中的油位。清潔液壓油需要及時(shí)補(bǔ)充。維護(hù)期間必須用酒精清潔儲(chǔ)罐過濾器元件。

3. Regularly check the oil level in the oil tank. Clean hydraulic oil needs to be replenished in time. The tank filter elements must be cleaned with alcohol during maintenance.

4.正確選擇液壓油對(duì)于確保增壓泵的率和長壽命關(guān)重要。

4. Correct selection of hydraulic oil is very important to ensure high efficiency and long life of booster pump.

如何更換機(jī)油？方法如下：

How to change the oil? The method is as follows:

支撐前軸并將車輪移離地面。拆下燃油箱蓋，回油管的放油塞和回轉(zhuǎn)單元。高速啟動(dòng)發(fā)動(dòng)機(jī)約10分鐘，并排空儲(chǔ)油箱，方向盤增壓泵和轉(zhuǎn)向器液壓油。停止發(fā)動(dòng)機(jī)，然后將方向盤向左和向右旋轉(zhuǎn)，以排出所有剩余的液壓油。更換濾芯，加高液壓油并從液壓系統(tǒng)中排出空氣。

Support the front axle and move the wheels off the ground. Remove fuel tank cap, drain plug of return line and rotary unit. Start the engine at high speed for about 10 minutes and drain the oil tank, steering wheel booster pump and steering gear hydraulic oil. Stop the engine and turn the steering wheel to the left and right to drain all remaining hydraulic oil. Change the filter element, increase the hydraulic oil and exhaust air from the hydraulic system.

自動(dòng)上料攪拌車方向盤動(dòng)力轉(zhuǎn)向泵的維護(hù)情況了解就是這樣，你明白了嗎？
