If there is a problem with the fully automatic mixer, but the cause of the failure is not found, it will have an adverse impact on the directional booster pump and is more likely to cause damage.

全自動(dòng)攪拌車轉(zhuǎn)向助力泵，我們通常稱為動(dòng)力轉(zhuǎn)向泵，是轉(zhuǎn)向助力系統(tǒng)的動(dòng)力轉(zhuǎn)向和轉(zhuǎn)向系統(tǒng)的核心。對于重型清障車，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)更為重要。

The power steering pump of automatic mixer, which we usually call power steering pump, is the core of power steering and steering system of power steering system. The hydraulic steering system is more important for the heavy-duty wrecker because of the mechanical steering force and the driver's labor intensity.

通用葉片泵包括在內(nèi)部腔體中具有雙彎曲曲線的泵體，帶槽的轉(zhuǎn)子，葉片等。其中一些安裝在發(fā)動(dòng)機(jī)后輪的飛輪殼上，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葉片槽向外移動(dòng)，并緊靠泵體的內(nèi)壁，其容積大于封閉的容積。在轉(zhuǎn)子旋轉(zhuǎn)期間，葉片之間的空間連續(xù)增加。實(shí)現(xiàn)了吸油，壓油的過程。轉(zhuǎn)子每旋轉(zhuǎn)一圈，吸油量和油壓就完成兩次。泵體內(nèi)還有一個(gè)閥以限制壓力。當(dāng)轉(zhuǎn)向系統(tǒng)的外部負(fù)載增加，導(dǎo)致油壓上升到一定值時(shí)，閥打開以負(fù)載。節(jié)流閥和流量控制閥也安裝在泵體內(nèi)，以確保增壓泵的排量基本恒定。

The general vane pump includes the pump body with double curved curve in the inner cavity, the rotor with groove, the blade, etc. Some of them are mounted on the flywheel housing of the rear wheels 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 blade moves outward along the blade groove under the action of centrifugal force, and is close to the inner wall of the pump body, and its volume is larger than the closed volume. During the rotation of the rotor, the space between the blades increases continuously. The process of oil absorption and oil pressure is realized. Every time the rotor rotates, the oil absorption and oil pressure are completed twice. There is also a relief valve in the pump body to limit the pressure. When the external load of the steering system increases, causing the oil pressure to rise to a certain value, the relief valve opens to eliminate the load. Throttle valve and flow control valve are also installed in the pump body to ensure that the displacement of booster pump is basically constant.

轉(zhuǎn)向助力泵的使用和維護(hù)特別重要，因此必須執(zhí)行以下操作：

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

1.使用過程中，如果轉(zhuǎn)向泵助力器泄漏，撞擊或異常聲音，應(yīng)及時(shí)檢查并。

1. In case of leakage, impact or abnormal sound of steering pump booster during use, timely check and eliminate it.

2.全自動(dòng)攪拌車運(yùn)行一段時(shí)間后，應(yīng)及時(shí)更換液壓油濾清器。特別是在安裝新泵之后，應(yīng)在2500-3000后更換液壓油。

2. The hydraulic oil filter should be replaced in time after the automatic mixer runs for a period of time. Especially after the installation of a new pump, the hydraulic oil should be changed after 2500-3000 km.

3.定期檢查儲(chǔ)油罐的油位。清潔液壓油應(yīng)及時(shí)補(bǔ)充。維護(hù)期間，應(yīng)使用酒精清潔儲(chǔ)罐中的過濾器元件。

3. Check the oil level of oil tank regularly. Clean hydraulic oil should be replenished in time. During maintenance, the filter elements in the tank should be cleaned with alcohol.

4.正確選擇液壓油是確保增壓泵和長壽命的關(guān)鍵。

4. Correct selection of hydraulic oil is the key to ensure high efficiency and long service life of booster pump.

我們?nèi)绾螕Q油？方法如下：

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

支撐前軸，以使車輪保持不離地面的狀態(tài)。拆下油箱蓋，拆下回油管和回轉(zhuǎn)單元的放油螺塞。高速啟動(dòng)發(fā)動(dòng)機(jī)約10分鐘，以使油箱，方向盤增壓泵和轉(zhuǎn)向器中的液壓油排出。關(guān)閉發(fā)動(dòng)機(jī)，然后將方向盤左右轉(zhuǎn)動(dòng)極限位置，以排出所有殘留的液壓油。更換濾芯，加高液壓油，并排出液壓系統(tǒng)中的空氣。

Support the front axle to keep the wheels on the ground. Remove the oil tank cover, remove the oil return pipe and drain plug of the rotary unit. Start the engine at high speed for about 10 minutes to drain the hydraulic oil from the tank, steering wheel, booster pump and steering gear. Turn off the engine and turn the steering wheel to the limit position to drain all residual hydraulic oil. Change the filter element, increase the hydraulic oil, and exhaust the air in the hydraulic system.

全自動(dòng)攪拌車關(guān)于轉(zhuǎn)向泵維修介紹就是這些，希望對你有幫助。
