(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）控制攪拌筒的轉(zhuǎn)速。

(2) Control the speed of mixing drum.

攪拌裝置主要由攪拌筒及其輔助支撐構(gòu)件組成。4方自上料混凝土攪拌罐車是用于混凝土的裝載容器。旋轉(zhuǎn)時(shí)，混凝土沿葉片的螺旋方向移動(dòng)，并在連續(xù)提升和轉(zhuǎn)動(dòng)過程中混合并攪拌。在進(jìn)料和運(yùn)輸過程中，攪拌筒向前旋轉(zhuǎn)，混凝土沿葉片向內(nèi)移動(dòng)。當(dāng)排出時(shí)，混合鼓反轉(zhuǎn)并且混凝土沿著葉片向外排出。

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.

葉片是攪拌器中的主要部件，損壞或嚴(yán)重磨損會(huì)導(dǎo)致混凝土混合不均勻。另外，如果葉片的角度不合理，將導(dǎo)致混凝土分離。

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.

清潔系統(tǒng)的主要功能是清潔攪拌筒，有時(shí)在運(yùn)輸過程中進(jìn)行干燥攪拌筒。清潔系統(tǒng)還冷卻液壓系統(tǒng)。

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.

全封閉裝置采用旋轉(zhuǎn)密封技術(shù)密封攪拌車的進(jìn)出口，解決了傳統(tǒng)攪拌車水蒸發(fā)，砂漿分層，物料溢出，行車安全等問題。

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.

污泥對(duì)4方自上料混凝土攪拌罐車的影響

Influence of sludge on 4-square self feeding mixer

4方自上料混凝土攪拌罐車通常用于建筑行業(yè)，使用時(shí)無法避免污泥。這是污泥如何影響它。

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.發(fā)動(dòng)機(jī)尾氣排放降低，火花塞，氧傳感器和三效催化劑的使用壽命也縮短。

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

2.發(fā)動(dòng)機(jī)功率降低，加速不平穩(wěn)，油耗增加。

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

3.混凝土運(yùn)輸攪拌車的冷啟動(dòng)很困難。冷車的怠速無法達(dá)到規(guī)定的速度。在嚴(yán)重的情況下，冷車的怠速將被關(guān)閉，并且熱車之后的怠速低。

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.積碳也會(huì)使發(fā)動(dòng)機(jī)的活塞環(huán)卡住，影響活塞環(huán)的密封性能，攪拌機(jī)的油耗會(huì)增加，導(dǎo)致發(fā)動(dòng)機(jī)燃燒油，縮短使用引擎壽命。

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.
