In order to ensure the normal operation of small concrete mixer before use, it is necessary to check the equipment in advance. So let's learn what problems we need to check and understand before the equipment is running.

（1）水泵和供水系统的组件应完整且不应泄漏。

(1) The components of the pump and water supply system shall be complete and free from leakage.

（2）装置检验规程：

(2) Safety device inspection procedures:

1.液压系统应设有装置，以防止过载和液压冲击；溢流阀的调节压力不得大于液压泵的额定压力。

1. The hydraulic system shall be equipped with safety device to prevent overload and hydraulic impact; the regulating pressure of safety relief valve shall not be greater than the rated pressure of hydraulic pump.

2.小型混凝土搅拌机侧面和后部的保护装置应完好无损。

2. The side and rear protection devices of small concrete mixer shall be intact.

3.小型混凝土搅拌机应配备灭火设备。

3. Small concrete mixer shall be equipped with fire fighting equipment.

（3）检查制度规定：

(3) The inspection system stipulates that:

1.气缸应与支撑轮良好接触，并且不要跑开，移位或严重变形。

1. The cylinder should be in good contact with the supporting wheel, and do not run away, shift or seriously deform.

2.搅拌桶框架的缓冲器应无裂纹或损坏；搅拌桶中的叶片，料斗以及主卸料槽和辅助卸料槽不应严重磨损和变形。

2. There should be no crack or damage on the buffer of the mixing drum frame; the blades, hopper, main discharge tank and auxiliary discharge tank in the mixing drum should not be seriously worn and deformed.

3.搅拌桶，给料斗以及主，副出料槽中不应有明显的混凝土块。

3. There should be no obvious concrete block in mixing bucket, feeding hopper and main and auxiliary discharge tanks.

（4）液压系统检验规程：

(4) Hydraulic system inspection procedures:

1.取力器工作时应兼具稳定性，压力应符合设计的额定要求，不得有泄漏。

1. The power take-off should be stable when working, the pressure should meet the rated requirements of the design, and there should be no leakage.

2.液压系统的组成部分应完整完整，并且系统的工作压力应符合手册的要求。

2. The components of the hydraulic system should be complete, and the working pressure of the system should meet the requirements of the manual.

3.液压油的种类，质量，数量和使用应符合有关规定；热泵工作时油温不应超过80°C;管道连接应可靠；

3. The type, quality, quantity and use of hydraulic oil shall comply with relevant regulations; the oil temperature during heat pump operation shall not exceed 80 ° C; the pipeline connection shall be reliable;

4.每个液压控制部分的运动应灵活可靠。

4. The movement of each hydraulic control part shall be flexible and reliable.

小型混凝土搅拌机操作环境通常都不是很好，这也导致需要我们对设备在操作之前有详细的了解才行。在确保设备不存在有任何故障问题之后才能够操作使用设备正常运行，避免在操作中可能存在的各种不良问题。

Small concrete mixer operating environment is usually not very good, which also leads to the need for us to have a detailed understanding of the equipment before operation. After ensuring that the equipment does not have any fault problems, it can be operated and used normally, so as to avoid all kinds of bad problems that may exist in the operation.
