自动搅拌车液压油管怎么连接？经常有朋友买自动搅拌车的液压油管，不知道怎么改装，我们要了解它的工作原理。

How to connect the hydraulic oil pipe of the automatic mixer? A friend often buys the hydraulic oil pipe of an automatic mixer, and doesn't know how to modify it. We need to understand its working principle.

通过自动搅拌车底盘上的取力器，将自动搅拌车发动机的动力输送到液压油泵，产生高压液压油。高压液压油驱动液压马达高速旋转，减速器产生大扭矩驱动搅拌筒旋转。根据螺旋输送原理，搅拌筒内的叶片不断推动混凝土搅拌，避免混凝土凝结现象。

The power take-off on the chassis of the automatic mixer transmits the power of the engine of the automatic mixer to the hydraulic oil pump to generate high-pressure hydraulic oil. The high-pressure hydraulic oil drives the hydraulic motor to rotate at high speed, and the reducer generates large torque to drive the mixing drum to rotate. According to the principle of spiral transportation, the blades in the mixing drum continuously promote concrete mixing to avoid concrete setting.

自动搅拌车发动机输出的动力通过动力输出传输到液压油泵。液压油泵配有两根油管，一根接液压油箱，另一根接液压换向阀（两根油管的厚度不同）。方向阀有四个端口，其中两个连接到液压马达，另一个连接到液压油散热器的出油口。

The power output from the engine of the automatic mixer truck is transmitted to the hydraulic oil pump through the power output. The hydraulic oil pump is equipped with two oil pipes, one connected to the hydraulic oil tank and the other connected to the hydraulic reversing valve (the thickness of the two oil pipes is different). The directional valve has four ports, two of which are connected to the hydraulic motor and the other to the outlet of the hydraulic oil radiator.

此外还应该知道液压传动的优点：可以实现对搅拌罐的无极变速控制，罐体的转动速度和转动方向在设定范围内可以任意调节。液压系统装置重量轻，体积小，安装方便柔性连接灵活。液压系统工作平稳，震动小，操作换向时的缓冲小，操作方便。有自动过载保护装置，自行润滑，使用寿命长。液压元件标准化程度高，方便维修和替换。

In addition, we should also know the advantages of hydraulic transmission: it can realize the stepless speed change control of the mixing tank, and the rotation speed and direction of the tank can be adjusted arbitrarily within the set range. The hydraulic system device is light in weight, small in volume, convenient in installation and flexible in connection. The hydraulic system operates stably, with small vibration, small buffer when reversing, and convenient operation. With automatic overload protection device, self lubrication, long service life. Hydraulic components are highly standardized and easy to repair and replace.

另外自动搅拌车的液压系统在工作中，油液里会不可避免的产生各类杂质异物，主要有焊渣、油漆、胶皮、磨料、灰尘、水分以及油液氧化生成的胶状物质等。这些杂质夹到液压泵马达运动部件中，会破坏部件之间的润滑油膜，划伤柱塞、配油盘和各类阀等敏感部件，造成压力泄漏和高温，缩短泵马达使用寿命。

In addition, during the operation of the hydraulic system of the automatic mixer truck, various impurities and foreign matters will inevitably be produced in the oil, mainly including welding slag, paint, rubber, abrasive, dust, moisture, and colloidal substances generated by oil oxidation. These impurities caught in the moving parts of the hydraulic pump motor will damage the lubricating oil film between the parts, scratch the plunger, oil distribution plate, various valves and other sensitive parts, cause pressure leakage and high temperature, and shorten the service life of the pump motor.

大的颗粒如果堵塞控制油路的阻尼孔，或卡住阀芯，还会引起设备瞬间控制失效，如果一罐混凝土不能及时放出来的话，会造成非常大的连带损失；长期不更换液压油，油液的各项性能也会逐渐下降，引起工作无力，发热，和高温，严重的造成油液变质，会破坏泵马达内部配件。

If the large particles block the damping hole of the control oil circuit or block the valve core, the equipment will also lose control instantly. If a can of concrete cannot be released in time, it will cause very large associated losses; If the hydraulic oil is not replaced for a long time, the performance of the oil will gradually decline, resulting in weak work, heat, and high temperature, and serious deterioration of the oil, which will damage the internal parts of the pump motor.
