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）水泵和供水系統的組件應完整且不應泄漏。

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

（2）裝置檢驗規程：

(2) Safety device inspection procedures:

1.液壓系統應設有裝置，以防止過載和液壓沖擊；溢流閥的調節壓力不得大于液壓泵的額定壓力。

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.小型混凝土攪拌機側面和后部的保護裝置應完好無損。

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

3.小型混凝土攪拌機應配備滅火設備。

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

（3）檢查制度規定：

(3) The inspection system stipulates that:

1.氣缸應與支撐輪良好接觸，并且不要跑開，移位或嚴重變形。

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

2.攪拌桶框架的緩沖器應無裂紋或損壞；攪拌桶中的葉片，料斗以及主卸料槽和輔助卸料槽不應嚴重磨損和變形。

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.攪拌桶，給料斗以及主，副出料槽中不應有明顯的混凝土塊。

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

（4）液壓系統檢驗規程：

(4) Hydraulic system inspection procedures:

1.取力器工作時應兼具穩定性，壓力應符合設計的額定要求，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.液壓系統的組成部分應完整完整，并且系統的工作壓力應符合手冊的要求。

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.液壓油的種類，質量，數量和使用應符合有關規定；熱泵工作時油溫不應超過80°C;管道連接應可靠；

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.每個液壓控制部分的運動應靈活可靠。

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

小型混凝土攪拌機操作環境通常都不是很好，這也導致需要我們對設備在操作之前有詳細的了解才行。在確保設備不存在有任何故障問題之后才能夠操作使用設備正常運行，避免在操作中可能存在的各種不良問題。

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.
