At present, the concrete mixer is an indispensable means of transportation for urban construction roads, bridges, houses, water conservancy projects, mixing stations and so on. Small concrete mixer truck has the characteristics of narrow body, short wheelbase, small turning radius and so on. It has a strong advantage in the limited height, wide and long working environment. Small concrete mixer belongs to industrial vehicles, so it is very important to make inspection regulations. Next, let's take a look at what inspection regulations small concrete mixer needs to comply with.
1、 Inspection rules of mixing system
1. The cylinder should be in good contact with the supporting roller, and should not deviate, move or deform seriously.
2. There should be no crack or damage on the buffer part of the mixing drum frame; the blades, feeding hopper and main and auxiliary discharge trough in the mixing drum should not be seriously worn and deformed.
3. There should be no obvious concrete block in mixing drum, feeding hopper and main and auxiliary discharge tank.
2、 Hydraulic system inspection rules
1. When the power take-off works, it should be combined smoothly, and the pressure should meet the rated requirements of the design, and there should be no leakage.
2. The hydraulic system parts should be complete and in good condition, and the working pressure of the system should meet the requirements of the manual.
3. The model, quality, quantity and use of hydraulic oil shall comply with relevant regulations; the oil temperature of heat dissipation pump shall not exceed 80 ℃; pipeline connection shall be reliable; corrosion, deformation, aging, damage and oil leakage shall not be allowed.
4. The movement of each hydraulic control part should be flexible and reliable.
3、 Inspection rules of water supply system供水系统水泵及部件应齐全完整，不应泄漏。
The water pump and parts of the water supply system shall be complete and complete without leakage.
4、 Safety device inspection rules
1. The hydraulic system shall be equipped with safety device to prevent overload and hydraulic impact; the adjustment pressure of safety relief valve shall not be greater than the rated pressure of hydraulic pump.
2. The side and rear protective devices of small concrete mixer truck shall be complete and intact.
3. Small concrete mixer shall be equipped with fire fighting equipment.
Strict specification is an important work for the safe use of small concrete mixer. I hope you can check the vehicle according to the above inspection regulations.
