Maintenance of small concrete automatic loading mixer

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，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: hydraulic system is the core system of mixer truck. In order to ensure that the mixer truck can work normally and the mixing tank can operate normally, check the hydraulic oil level of the oil circuit radiator and reducer before each vehicle start to ensure that the oil level indication is within the window range. At the same time, its cleanliness shall be ensured to prevent dust particles and moisture from polluting the hydraulic oil of the system, resulting in the failure or damage of the system.

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 water volume of pneumatic water supply system is generally three-quarters of the water tank; When the vehicle is running, all valves in the waterway system shall be closed 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 or change the water tank at will to avoid the impact of heavy objects; Frequently check whether the valve body is blocked or abnormal; When it is used in an environment with the possibility of icing, the water supply system shall empty the stored water to prevent the pipeline from freezing and cracking; Regularly check the tightness of the system. After disassembly and repair, the key parts shall be coated with thread sealant.

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: after 50h of initial use, timely check whether the bolts of the tank and other parts are loose. Check the lubrication of the supporting wheel and raceway every day before driving. Open the supporting wheel shield once a month to clean the internal oil stain and add lubricating grease.

小型混凝土搅拌车的保养禁忌

Maintenance of small concrete mixer

小型混凝土搅拌车在某些行业的运输方面可谓是不可或缺的，不过近期很多用户向我们咨询为什么它的工作效率越来越低，那么出现这一状况的原因可能是因为没有及时保养维修，再者或许是因为没有正确的保养，相信后者所占的比例应该是很大的，那么具体它有哪些保养禁忌呢？

Small concrete mixers are indispensable in the transportation of some industries, but recently many users have asked us why their work efficiency is getting lower and lower. The reason for this may be that they have not been maintained in time, or that they have not been properly maintained. I believe the latter should account for a large proportion, So what are the specific maintenance taboos?

1、忌机油只加不换；

1. Avoid only adding engine oil without changing it;

2、混凝土商砼车忌缸套和活塞新品不经选配即安装；

2. It is forbidden to install new cylinder liners and pistons of concrete commercial vehicles without selection;

3、水泥运输车忌不检查柱塞行程余量。

3. Do not check the plunger stroke allowance of cement truck.
