1. Each cylinder, control valve and motor shall operate according to the requirements of concrete mixing process. The control of each cylinder, control valve and motor must be accurate, stable and reliable. From the manufacturer of the loading concrete mixer truck, it can ship the concrete produced by the mixing plant (station) or the aggregate (sand, stone), cement and water mixed according to the proportion. During the transportation, the wet material is continuously mixed slowly to prevent the initial setting and segregation of the concrete during the transportation.

控制系统有自动和手动两种工作方式，它们相互独立，相互制约。

The control system has two working modes: automatic and manual, which are independent and restrict each other.

2.系统发展具有一个良好的抗干扰能力和完善的报警自保护管理功能；

2. The system development has a good anti-interference ability and perfect alarm self-protection management function;

3.通过与计算机通讯,可以进行显示信息系统管理工作状态、故障报警；

3. Through communication with the computer, it can display the working status and fault alarm of information system management;

一个工作周期内搅拌车主机系统少应清洗1次。每天可以生产活动结束后，则应对搅拌车主机信息进行比较的清洗，方法是：在清洗服务过程中，将水及少许石子放进搅拌主机内通过搅拌5～10min，清洗后将机内物料管理全部有效，不得有积水、积料;停机后再冲洗以及管道，搅拌罐内外环境灰尘和粘附的混凝土。

The mixer truck host system shall be cleaned at least once in a working cycle. After the daily production activities, the main engine information of the mixer truck shall be cleaned comprehensively. The method is: during the cleaning service, put water and a little stone into the mixer main engine and mix for 5 ~ 10min. After cleaning, all the material management in the mixer shall be effectively removed without ponding and accumulation; After shutdown, wash the and pipes to remove dust and adhered concrete inside and outside the mixing tank.

一般这种情况下，JS1000型搅拌设备主机之间加水约150～180kg左右，其他产品型号选择主机可据此分析增减，也可自备高压水枪或者进行数据清理。

Generally, in this case, about 150 ~ 180kg water is added between the main machines of JS1000 mixing equipment. The main machines of other product models can analyze the increase or decrease according to this, or provide their own high-pressure water gun or clean the data.

在冲洗搅拌主机料门时，应避免上部冲洗下的积料形成异物卡滞料门现象。搅拌过程中，若混凝土运输车较长时间没有到位(超过20～30min，尤其在夏季)，应加水对搅拌机进行简易清洗。

When flushing the material door of the mixing machine, avoid the accumulation of material under the upper flushing to form the phenomenon of foreign matter blocking the material door. During mixing, if the concrete truck is not in place for a long time (more than 20 ~ 30min, especially in summer), add water to simply clean the mixer.

搅拌车设备正常生产期间，要定期检查搅拌筒内及搅拌轴上混凝土的凝固情况，如有凝结应及时按要求进行人工铲除。人工清理搅拌筒前，必须切断电源、气路，放净余气、锁好控制室;人工清理搅拌筒时，严禁猛烈敲击搅拌轴、搅拌臂及搅拌叶片。

During the normal production of mixer truck equipment, the solidification of concrete in the mixing drum and on the mixing shaft shall be checked regularly. If there is condensation, it shall be removed manually in time as required. Before manually cleaning the mixing drum, the power supply and gas circuit must be cut off, the residual gas must be discharged, and the control room must be locked; When manually cleaning the mixing drum, it is strictly prohibited to knock the mixing shaft, mixing arm and mixing blade violently.
