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.

自动上料搅拌车转向助力泵，我们通常把它叫做方向机助力泵，它是清障车转向助力系统的动力源，也是转向系统的心脏部分。对于重型清障车来说，由于机械式方向机，驾驶员操作劳动强度大，所以液压转向系统就更为重要。

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.

一般的叶片泵是由一个内腔双圆弧曲线的泵体带槽转子.叶片等零件组成。有的安装在发动机后端的飞轮壳上，也是靠正时齿轮驱动。当发动机运转时，带动助力泵转子转动，叶片在离心力的作用下，沿叶片槽向外移动，紧靠泵体的内壁，在转子转动过程中，由于叶片间封闭的容积不断的增加和减小实现了吸油和压油的过程。

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.

转子每转一周，完成吸油和压油二次。在泵体内还有阀以限制压力。当转向系外部负荷增加，导致油压升高到一定数值时，阀开启卸掉负荷。泵体内还安装有节流阀和流量控制阀，以保证助力泵的排量基本上处于稳定性。

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.

方向机助力泵的使用与维护尤为重要，因此，必须做到以下几点：

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

一、在使用中如发现方向机助力泵渗漏，冲击或有异常的噪音，应及时检查排除。

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

二、自动上料搅拌车运行一段时间后，应及时更换液压油几滤芯，尤其是新泵装车后使用2500-3000应更换液压油。

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、定期检查储油罐的油平面，不足应及时补充清洁的液压油，储油罐内的滤芯应在保养时用酒精清洗干净。

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、正确选择液压油是保证助力泵率，延长寿命的关键。

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

我们应该如何进行换油呢？方法如下：

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

支起前桥，使车轮离地。拆下储油罐盖，拆下回油管及方向机放油螺塞。启动发动机高速运转10分钟左右，使储油罐，方向机助力泵，方向机内的液压油排出。发动机熄火，左右转动方向盘极限位置，把残余的液压油全部排出。更换滤芯，加液压油规定的高度，排净液压系统的空气。

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.
