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.

全自动搅拌车转向助力泵，我们通常称为动力转向泵，是转向助力系统的动力转向和转向系统的核心。对于重型清障车，由于机械转向力和驾驶员的劳动强度，液压转向系统更为重要。

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.

通用叶片泵包括在内部腔体中具有双弯曲曲线的泵体，带槽的转子，叶片等。其中一些安装在发动机后轮的飞轮壳上，并由正时齿轮驱动。当发动机运转时，增压泵的转子被驱动旋转，叶片在离心力的作用下沿叶片槽向外移动，并紧靠泵体的内壁，其容积大于封闭的容积。在转子旋转期间，叶片之间的空间连续增加。实现了吸油，压油的过程。转子每旋转一圈，吸油量和油压就完成两次。泵体内还有一个阀以限制压力。当转向系统的外部负载增加，导致油压上升到一定值时，阀打开以负载。节流阀和流量控制阀也安装在泵体内，以确保增压泵的排量基本恒定。

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.

转向助力泵的使用和维护特别重要，因此必须执行以下操作：

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

1.使用过程中，如果转向泵助力器泄漏，撞击或异常声音，应及时检查并。

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

2.全自动搅拌车运行一段时间后，应及时更换液压油滤清器。特别是在安装新泵之后，应在2500-3000后更换液压油。

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.定期检查储油罐的油位。清洁液压油应及时补充。维护期间，应使用酒精清洁储罐中的过滤器元件。

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.正确选择液压油是确保增压泵和长寿命的关键。

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

我们如何换油？方法如下：

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

支撑前轴，以使车轮保持不离地面的状态。拆下油箱盖，拆下回油管和回转单元的放油螺塞。高速启动发动机约10分钟，以使油箱，方向盘增压泵和转向器中的液压油排出。关闭发动机，然后将方向盘左右转动极限位置，以排出所有残留的液压油。更换滤芯，加高液压油，并排出液压系统中的空气。

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.
