Often check whether the transmission oil level of commercial concrete cement mixer truck is normal. The way to check the automatic transmission oil of commercial concrete cement mixing truck is different from that of engine oil. The engine oil is checked when the vehicle is cold. However, the transmission oil of commercial concrete cement mixing truck needs to preheat the oil to about 50 ℃, and then put the gear lever in the parking gear after staying in each gear for 2 seconds. At this moment, the normal oil level of the dipstick should be located between the high and low lines, If not, oil products of the same quality shall be added in time.

把握好替換商品混凝土水泥攪拌運(yùn)輸車(chē)變速箱油的周期。在正常運(yùn)用的過(guò)程中，商品混凝土水泥攪拌運(yùn)輸車(chē)變速箱油的工作溫度通常在120攝氏度左右，因而對(duì)油品的質(zhì)量需求很高，還有必要保持清潔。商品混凝土水泥攪拌運(yùn)輸車(chē)變速箱油運(yùn)用時(shí)間長(zhǎng)了以后會(huì)發(fā)生油垢，有可能會(huì)構(gòu)成油泥，會(huì)加大各摩擦片和各部件的磨損，并且還影響體系油壓，使動(dòng)力傳遞受到影響。臟油中的油泥會(huì)使各閥體中閥體的移動(dòng)不暢，油壓操控受影響，從而使商品混凝土水泥攪拌運(yùn)輸車(chē)自動(dòng)變速箱出現(xiàn)異常。

Grasp the cycle of replacing the gearbox oil of commercial concrete cement mixer truck. During normal operation, the operating temperature of gearbox oil of commercial concrete cement mixer truck is usually about 120 ℃, so there is a high demand for oil quality, and it is necessary to keep it clean. The gearbox oil of commercial concrete cement mixer truck will produce oil dirt after a long service time, which may form oil sludge, increase the wear of friction plates and components, and also affect the system oil pressure and power transmission. The oil sludge in the dirty oil will hinder the movement of the valve body in each valve body and affect the oil pressure control, so as to make the automatic transmission of commercial concrete cement mixer truck abnormal.

正確地替換變速箱油。當(dāng)前較好的換油辦法是動(dòng)態(tài)換油，選用專(zhuān)用的變速箱清潔設(shè)備，在變速箱工作的過(guò)程中，將舊油充沛循環(huán)，排放潔凈后再參加新的變速箱油，從而使換油率高達(dá)90以上。商品混凝土水泥攪拌運(yùn)輸車(chē)司機(jī)應(yīng)培育自動(dòng)查看、保護(hù)、養(yǎng)護(hù)的認(rèn)識(shí)，能夠?qū)W習(xí)一些保護(hù)、養(yǎng)護(hù)商品混凝土水泥攪拌運(yùn)輸車(chē)的基本知識(shí)，仔細(xì)閱覽隨車(chē)運(yùn)用說(shuō)明，記住一些必要數(shù)據(jù)等?？茖W(xué)養(yǎng)車(chē)，才干確保商品混凝土水泥攪拌運(yùn)輸車(chē)處于杰出的技能狀況，確保行車(chē)。

Replace the transmission oil correctly. At present, the better oil change method is dynamic oil change. Special transmission cleaning equipment is selected. During the operation of the transmission, the old oil is fully circulated, and the new transmission oil is added after being discharged and cleaned, so that the oil change rate is more than 90. The driver of commercial concrete cement mixer truck shall cultivate the understanding of automatic viewing, protection and maintenance, be able to learn some basic knowledge of protection and maintenance of commercial concrete cement mixer truck, carefully read the onboard operation instructions, remember some necessary data, etc. Only by maintaining the vehicle scientifically can we ensure that the commercial concrete cement mixer truck is in an excellent technical condition and ensure driving safety.
