(1) Control the rotation direction of the mixing drum to make it rotate forward in the process of feeding and transportation, and reverse rotation during unloading.

（2）控制搅拌筒的转速。

(2) Control the speed of mixing drum.

搅拌装置主要由搅拌筒及其辅助支撑构件组成。4方江南app平台官网 车是用于混凝土的装载容器。旋转时，混凝土沿叶片的螺旋方向移动，并在连续提升和转动过程中混合并搅拌。在进料和运输过程中，搅拌筒向前旋转，混凝土沿叶片向内移动。当排出时，混合鼓反转并且混凝土沿着叶片向外排出。

The mixing device is mainly composed of mixing drum and its auxiliary supporting components. The 4-square self loading mixer is a container for loading concrete. When rotating, the concrete moves along the spiral direction of the blade and is mixed and mixed during continuous lifting and rotation. During feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blades. When discharged, the mixing drum reverses and the concrete is discharged outward along the blades.

叶片是搅拌器中的主要部件，损坏或严重磨损会导致混凝土混合不均匀。另外，如果叶片的角度不合理，将导致混凝土分离。

Blade is the main part of the mixer, damage or serious wear will lead to uneven mixing of concrete. In addition, if the blade angle is not reasonable, it will lead to concrete separation.

清洁系统的主要功能是清洁搅拌筒，有时在运输过程中进行干燥搅拌筒。清洁系统还冷却液压系统。

The main function of the cleaning system is to clean the mixing drum, sometimes drying the mixing drum during transportation. The cleaning system also cools the hydraulic system.

全封闭装置采用旋转密封技术密封搅拌车的进出口，了传统搅拌车水蒸发，砂浆分层，物料溢出，行车等问题。

The rotary sealing technology is used to seal the inlet and outlet of the mixer, which solves the problems of water evaporation, mortar stratification, material overflow, driving safety and so on.

污泥对4方江南app平台官网 车的影响

Influence of sludge on 4-square self feeding mixer

4方江南app平台官网 车通常用于建筑行业，使用时无法避免污泥。这是污泥如何影响它。

The 4-party self feeding mixer is usually used in the construction industry, and sludge cannot be avoided when it is used. This is how the sludge affects it.

1.发动机尾气排放降低，火花塞，氧传感器和三效催化剂的使用寿命也缩短。

1. The engine exhaust emission is reduced, and the service life of spark plug, oxygen sensor and three-way catalyst is also shortened.

2.发动机功率降低，加速不平稳，油耗增加。

2. The engine power is reduced, the acceleration is not stable, and the fuel consumption is increased.

3.混凝土运输搅拌车的冷启动很困难。冷车的怠速无法达到规定的速度。在严重的情况下，冷车的怠速将被关闭，并且热车之后的怠速低。

3. It is very difficult to start the mixer truck. The idle speed of the cold car cannot reach the specified speed. In severe cases, the idle speed of the cold car will be turned off, and the idle speed after the hot car will be low.

4.积碳也会使发动机的活塞环卡住，影响活塞环的密封性能，搅拌机的油耗会增加，导致发动机燃烧油，缩短使用引擎寿命。

4. Carbon deposition will also cause the piston ring of the engine to jam and affect the sealing performance of the piston ring. The fuel consumption of the mixer will increase, resulting in the engine burning oil and shortening the service life of the engine.
