混凝土自上料搅拌车排气制动装置如何看？
混凝土自上料搅拌车排气制动装置由排气制动按钮阀、废气工作缸、排气制动蝶阀、停油气缸组成。排气制动操纵方便，简单有效。那么混凝土自上料搅拌车排气制动装置如何看？
The exhaust brake device of concrete self-feeding mixer consists of exhaust brake button valve, exhaust gas working cylinder, exhaust brake butterfly valve and oil and gas stop cylinder. Exhaust brake is easy to operate, simple and effective. So how to look at the exhaust brake device of the concrete mixing truck?
在下长坡时，使用排气制动可以减少行车制动的次数，降低制动鼓的温升，提高制动的可靠性。混凝土自上料搅拌车使用排气制动时，能减少发动机油料的供给以断油，能节省燃料。
When going down long slope, using exhaust brake can reduce the number of service braking, reduce the temperature rise of brake drum and improve the reliability of braking. When the concrete self-feeding mixer uses exhaust brake, it can reduce the supply of engine oil and even cut off oil, and can save fuel.
驾驶员使用排气制动时，用脚踩驾驶室底板上左下方的排气制动按钮阀，按钮阀受力打开气的通道，压缩空气进入废气工作缸。废气工作缸活塞受压缩空气的压力移动，带动推杆，推杆带动排气制动蝶阀，蝶阀转动将排气管堵死。
When the driver uses the exhaust brake, step on the exhaust brake button valve at the bottom left of the cab floor with his feet. The button valve is forced to open the gas channel and the compressed air enters the exhaust gas working cylinder. The exhaust gas cylinder piston is moved by the pressure of compressed air, which drives the push rod, which drives the exhaust brake butterfly valve, and the butterfly valve rotates to block the exhaust pipe.
发动机活塞在工作中的排气行程须克服此压力，因而大大增加了发动机制动的功率。故当采用排气制动时，发动机活塞在发动机排气行程时，活塞受气体的反压力，经过曲轴和传动系传车轮，增加了混凝土自上料搅拌车车轮的转动阻力，降低了车速。
The exhaust stroke of the engine piston must overcome this pressure, thus greatly increasing the power of engine braking. Therefore, when the exhaust brake is used, the engine piston in the engine exhaust stroke, the piston by the gas back pressure, through the crankshaft and transmission system to the wheel, increased the concrete from the feeding mixing car wheel rotation resistance, reduce the speed.
混凝土自上料搅拌车厂家提醒，在采用排气制动时，搅拌车发动机实质上变为一台空压机，来消耗能量控制车速。虽然停止发动机燃油的供给，但发动机润滑、冷却系统在正常的工作，只是由输出能量，变为消耗能量，对发动机无害。
Concrete mixing truck manufacturers remind that when exhaust braking is used, the mixing truck engine essentially becomes an air compressor to consume energy to control the speed. Although stop engine fuel supply, but the engine lubrication, cooling system in the normal work, just by the output of energy, into energy consumption, harmless to the engine.
混凝土自上料搅拌车排气制动装置如何看？以上便是问题讲解了，当然进行操作时，应注意排气制动装置各部件的完好，如果有损坏，应修理或更换。更多内容了解就来网站www.jfjiaobanche.com看看吧。
How to look at the exhaust brake device of concrete mixing truck? The above is the problem explained, of course, when operating, we should pay attention to the integrity of all parts of the exhaust brake device. If there is damage, it should be repaired or replaced. For more information, visit www.jfjiaobanche.com.
