The concrete automatic feeding mixer will find that the oil pump will be damaged and the hydraulic oil will be polluted within a period of time after use. The time varies, but the hydraulic oil needs to be replaced. Here's how to replace and use the hydraulic oil effectively:

卸油前的准备工作搅拌器每脚缸均充分膨胀，包括摆动、膨胀、垂直缸等。排油功将小型混凝土搅拌机泵缸内的液压油取出，将混凝土活塞和泵缸连杆自由或连杆阀块取出。

Before unloading, each foot cylinder of agitator is fully expanded, including swing, expansion, vertical cylinder, etc. The oil drain function takes out the hydraulic oil in the pump cylinder of the small concrete mixer, and takes out the concrete piston and the connecting rod of the pump cylinder or the connecting rod valve block.
                     

清洗小泵车油箱，然后用面团将油箱内的杂质粘干净。清洗元件、液压阀、阀块、油箱防水挡板、二次构造柱压铸机具有较大的排水量。速度快，效率高。注满液压油。泵送和搅拌液压系统，用于排油。放油分配系统。油排水管道，为了保证油箱内油的顺利冲洗，拆下的排油管连接低于油箱液位。小型混凝土搅拌机泵车吊臂液压系统排油。

Clean the oil tank of small pump truck, and then use dough to clean the impurities in the oil tank. The cleaning element, hydraulic valve, valve block, oil tank waterproof baffle and secondary structure column die casting machine have large displacement. Fast and efficient. Fill with hydraulic oil. Pumping and mixing hydraulic system for oil drainage. Drain oil distribution system. In order to ensure the smooth flushing of the oil in the oil tank, the connection of the removed oil drain pipe is lower than the liquid level of the oil tank. Small concrete mixer pump truck boom hydraulic system oil drainage.
