Concrete mixing machinery and equipment are widely used in engineering construction. Xiaobian reminds you to check carefully when purchasing concrete mixing machinery and equipment.

检查混凝土搅拌机械设备整体外观

Check the overall appearance of concrete mixing machinery and equipment

正规全新的混凝土搅拌机械设备主要结构无明显变形、脱焊、开裂。安装符合规定要求，零部件及附属装置齐全完整，整机整洁，无锈蚀，机内无明显积砼。而翻新机在细节上存在瑕疵，消费者应仔细查看。

There is no obvious deformation, desoldering and cracking in the main structure of the normal new concrete mixing machinery. The installation meets the specified requirements, the parts and accessories are complete and complete, the whole machine is clean without rust, and there is no obvious concrete accumulation in the machine. However, there are flaws in the details of the refurbished machine, so consumers should check them carefully.

检查混凝土搅拌机械设备装置

Check the safety device of concrete mixing machinery and equipment

正规全新的混凝土搅拌机械设备上料斗上、下限位装置动作灵敏可靠。离合器传递动力有效，分离彻底、制动可靠，上料斗电机制动可靠，无下滑现象。钢丝绳型号、质量及规格符合规定，磨损和断丝不超过规定，绳卡符合使用规范，开式齿轮及皮带轮护罩齐全，上料斗挂钩及轨道上的插销完好、齐全。翻新机远远达不到这种效果。

Regular new concrete mixing machinery and equipment upper hopper, lower limit device sensitive and reliable action. Clutch transmission power is effective, separation is complete, braking is reliable, hopper motor braking is reliable, no sliding phenomenon. The model, quality and specification of the steel wire rope meet the requirements, the wear and broken wire do not exceed the requirements, the rope clip meets the use specifications, the open gear and pulley shield are complete, the safety hook of the upper hopper and the safety bolt on the track are complete. The refurbished machine is far from achieving this effect.

检查混凝土搅拌机械设备传动装置

Check the driving device of concrete mixing mechanical equipment

正规全新的混凝土搅拌机械设备传动装置运转平稳，各部连接可靠，齿轮和良好，轴向和径向间隙符合规定，摩擦传动轮磨损不超过规定。传动皮带松紧适宜、受力均匀，无断裂。链条、链轮无咬齿现象。减速箱运转正常无异响，密封良好。电机工作无异响，温升符合规定。绝缘良好，接地符合要求。

The normal new concrete mixing mechanical equipment transmission device runs smoothly, the connection of each part is reliable, the gear and shaft are good, the axial and radial clearance meet the requirements, and the wear of friction drive wheel does not exceed the requirements. The drive belt is suitable for tightness, uniform force and no fracture. The chain and sprocket have no bite. The gearbox operates normally without abnormal noise and is well sealed. The motor works without abnormal noise, and the temperature rise meets the requirements. The insulation is good and the grounding meets the requirements.
