混凝土自上料攪拌車(chē)排氣制動(dòng)裝置如何看？
混凝土自上料攪拌車(chē)排氣制動(dòng)裝置由排氣制動(dòng)按鈕閥、廢氣工作缸、排氣制動(dòng)蝶閥、停油氣缸組成。排氣制動(dòng)操縱方便，簡(jiǎn)單有效。那么混凝土自上料攪拌車(chē)排氣制動(dòng)裝置如何看？
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?
在下長(zhǎng)坡時(shí)，使用排氣制動(dòng)可以減少行車(chē)制動(dòng)的次數(shù)，降低制動(dòng)鼓的溫升，提高制動(dòng)的可靠性。混凝土自上料攪拌車(chē)使用排氣制動(dòng)時(shí)，能減少發(fā)動(dòng)機(jī)油料的供給以斷油，能節(jié)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.
駕駛員使用排氣制動(dòng)時(shí)，用腳踩駕駛室底板上左下方的排氣制動(dòng)按鈕閥，按鈕閥受力打開(kāi)氣的通道，壓縮空氣進(jìn)入廢氣工作缸。廢氣工作缸活塞受壓縮空氣的壓力移動(dòng)，帶動(dòng)推桿，推桿帶動(dòng)排氣制動(dòng)蝶閥，蝶閥轉(zhuǎn)動(dòng)將排氣管堵死。
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.
發(fā)動(dòng)機(jī)活塞在工作中的排氣行程須克服此壓力，因而大大增加了發(fā)動(dòng)機(jī)制動(dòng)的功率。故當(dāng)采用排氣制動(dòng)時(shí)，發(fā)動(dòng)機(jī)活塞在發(fā)動(dòng)機(jī)排氣行程時(shí)，活塞受氣體的反壓力，經(jīng)過(guò)曲軸和傳動(dòng)系傳車(chē)輪，增加了混凝土自上料攪拌車(chē)車(chē)輪的轉(zhuǎn)動(dòng)阻力，降低了車(chē)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.
混凝土自上料攪拌車(chē)廠家提醒，在采用排氣制動(dòng)時(shí)，攪拌車(chē)發(fā)動(dòng)機(jī)實(shí)質(zhì)上變?yōu)橐慌_(tái)空壓機(jī)，來(lái)消耗能量控制車(chē)速。雖然停止發(fā)動(dòng)機(jī)燃油的供給，但發(fā)動(dòng)機(jī)潤(rùn)滑、冷卻系統(tǒng)在正常的工作，只是由輸出能量，變?yōu)橄哪芰?，?duì)發(fā)動(dòng)機(jī)無(wú)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.
混凝土自上料攪拌車(chē)排氣制動(dòng)裝置如何看？以上便是問(wèn)題講解了，當(dāng)然進(jìn)行操作時(shí)，應(yīng)注意排氣制動(dòng)裝置各部件的完好，如果有損壞，應(yīng)修理或更換。更多內(nèi)容了解就來(lái)網(wǎng)站www.pheenet.cn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.pheenet.cn.
