With the development of the times, people's demand for concrete mixer is increasing. Today, Xiaobian explained to you the use and maintenance points of the concrete loading mixer. Let's have a look!

1.液压驱动系统：液压系统是搅拌车的核心系统。为保证搅拌车能正常工作，搅拌罐能运转正常，必须在每次车辆发动前检查油路散热器和减速机的液压油位，保证油位指示在视窗范围内。同时要保证其清洁性，以免尘粒和水分等污染系统液压油，造成系统不能正常工作或损坏。

1. Hydraulic drive system: the hydraulic system is the core system of the mixer. In order to ensure that the mixer can work normally and the mixing tank can operate normally, the hydraulic oil level of the radiator and reducer of the oil circuit must be checked before the start of each vehicle to ensure that the oil level indication is within the window range. At the same time, it is necessary to ensure its cleanness, so as to prevent dust and moisture from polluting the hydraulic oil of the system and causing the system unable to work normally or damage.

2.供水系统：气压供水系统加水量一般在水箱的四分之三处为宜；车辆在行驶时水路系统中各个阀门均应处于关闭状态，以免影响车辆的制动性能，或烧结摩擦片，从而影响车辆的制动性能。禁止随意焊接和改动水箱，避免重物撞击；经常检查阀体是否堵塞或是否有工作异常；在有结冰可能的环境中使用时，供水系统必须排空存水，防止管路冻裂；经常检查系统的密封性，拆卸修理后，关键部位要涂螺纹密封胶。

2. Water supply system: the amount of water added to the air pressure water supply system is generally 3 / 4 of the water tank; each valve in the water system shall be closed when the vehicle is running, so as to avoid affecting the braking performance of the vehicle, or sintering the friction plate, thus affecting the braking performance of the vehicle. It is forbidden to weld and change the water tank at will to avoid heavy object impact; check whether the valve body is blocked or abnormal; when the water supply system is used in an environment with possibility of icing, drain the water to prevent the pipeline from frost cracking; check the tightness of the system regularly, and apply thread sealant to the key parts after disassembly and repair.

3.搅拌筒：初次使用50h要及时检查罐体及其他部位螺栓是否有松动，每天行车前要检查托轮与滚道的润滑，每个月打开一次托轮护罩，清理内部的油污并添加润滑油脂。

3. Mixing drum: check whether the bolts on the tank body and other parts are loose in time after the initial use of 50h. Check the lubrication of the supporting roller and the raceway before driving every day. Open the protective cover of the supporting roller once a month, clean the internal oil stain and add the lubricating grease.
