液压油泵、马达若发生故障，需及时更换下送往指定维修部维修，在拆下旧油泵、马达，装上新油泵、马达时，应注意以下几点：

If the hydraulic oil pump and motor fail, they should be replaced in time and sent to the designated professional maintenance department for maintenance. When removing the old oil pump and motor and installing the new oil pump and motor, the following points should be noted:

拆下旧油泵、马达时，应先拆下油管，须将油泵和油管上的各个油口立即密封，防止灰尘进入油泵及油管内，然后再将油泵从搅拌车上拆下；

When removing the old oil pump and motor, the oil pipe should be removed first, and all oil ports on the oil pump and oil pipe should be sealed immediately to prevent dust from entering the oil pump and oil pipe, and then the oil pump should be removed from the mixer truck;
            

平稳地装上油泵、马达，注意装配的对中良好，螺栓拧紧，启封油泵、马达油口，接上油管

Install the oil pump and motor smoothly, pay attention to the good alignment of the assembly, tighten the bolts, unseal the oil port of the oil pump and motor, and connect the oil pipe

所有油管安装完毕后，加注液压油规定的油位，并排空系统内的空气；

After all oil pipes are installed, fill hydraulic oil to the specified oil level and empty the air in the system;

检查中科自上料搅拌车油箱油位，若不到位，需加入清洁液压油到位；

Check the oil level of the tank of Zhongke self feeding mixer. If it is not in place, add clean hydraulic oil in place;

启动汽车发动机，怠速运行10分钟（油泵在空挡位置，搅拌筒不动的情况下），检查油泵、马达噪音情况及各油管是否有漏油现象；

Start the engine and run at idle speed for 10 minutes (when the oil pump is in neutral position and the mixing drum does not move), check the noise of the oil pump and motor and whether there is oil leakage in the oil pipes;
