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.
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.
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.
