搅拌车的液压泵吸油口应安装粗滤器，吸油口应与油箱底部有一定距离； 搅拌车出油口应安装高压精滤器，过滤效果应满足系统工作要求，防止污染。 物料堵塞引起的液压系统故障； 过滤网应安装在搅拌车的液压油箱隔板上，以去除回油过滤器未过滤的杂质。
The oil suction port of the hydraulic pump of the mixer truck should be installed with a coarse filter, and the oil suction port should be a certain distance from the bottom of the oil tank; High pressure fine filter shall be installed at the oil outlet of the mixer truck, and the filtering effect shall meet the working requirements of the system to prevent pollution. Hydraulic system failure caused by material blockage; The filter screen shall be installed on the diaphragm of the hydraulic oil tank of the mixer truck to remove the unfiltered impurities of the oil return filter.
搅拌车的液压缸上应安装金属保护圈，防止污物带入缸内，防止泥水和光辐射侵蚀液压缸造成泄漏； 液压元件安装前应检查、清洗内铁。 灰尘和杂质； 定期检查液压油，一旦油液变质、起泡、沉淀、油水分离等，应立即清洗系统并换油。
A metal protective ring shall be installed on the hydraulic cylinder of the mixer truck to prevent dirt from entering the cylinder and prevent leakage caused by muddy water and light radiation erosion of the hydraulic cylinder; Check and clean the inner iron before installing the hydraulic components. Dust and impurities; Check the hydraulic oil regularly. Once the oil deteriorates, bubbles, precipitates, oil-water separation, etc., clean the system and change the oil immediately.
Before the new oil is added into the oil tank of the mixer truck, it should be filtered before adding. If necessary, an intermediate oil tank can be set for sedimentation and filtration of new oil.
Avoid "high-grade and low-speed" driving, which makes the oil incomplete combustion, thus accumulating in the oil pipe to form sludge. Do not idle for a long time and drive at a low speed, which is easy to cause incomplete combustion of oil and accumulation of carbon layer. Use the oil with purity and quality up to standard. The purity of the oil is high. Yes, the oil can burn quickly and fully, which will reduce the amount of sludge. Therefore, it is very necessary to use matching small concrete mixer oil.
Avoid blocking the check valve during use and operation. This will cause the temperature in the tank shell to rise and the oil and gas will not be discharged, so the pressure in the shell will rise and the lubricating oil consumption will increase. Check regularly, and some consumables need to be replaced, such as replacing the invalid oil seal in time. Some oil seals are aging and lose elasticity. Solve the sealing of various oil pipe joints when disassembling or replacing parts. Often disassembled, it is easy for the sliding wire to break and loosen, resulting in oil leakage.
Avoid oil spilling from the mixer wheel hub, excessive lubricating grease in the wheel hub bearing and cavity, poor quality and aging failure. Too frequent braking of small concrete mixer leads to excessive hub temperature.
