With the continuous expansion of highway, railway and urban road construction projects, the company's construction market is gradually expanding need to use concrete, and concrete mixer is a common construction equipment, but the use of the process of problems are not less, such as equipment axle problems. So let's analyze it.
Reasons for holding the shaft of concrete mixer truck:
The agitator holds the shaft because in the process of mixing powder, sand and liquid formed by the mixture of adhesives, adhesion to the mixing shaft and the mixing arm, accumulated over a long period of time on its surface to form a layer of very thick and difficult to clean the adhesives.
Harm of concrete mixing truck holding shaft:
Concrete mixer manufacturer thinks that the quality of concrete is affected, and the concrete produced after the mixer holds the shaft is not evenly mixed. The load of concrete mixer is increased and the energy consumption is increased. It affects the life of wear-resistant parts and shaft end seal, speeds up the wear of wear-resistant parts, and the wear of the stirring arm after holding the shaft is very serious, and the service life is greatly shortened.
Methods to prevent the concrete mixer from holding the shaft:
Adjust feeding order and time. The aggregate and powder are pre-mixed and then fall into the host (but the aggregate must be part of the next), so that the powder is attached to the aggregate to a certain extent, reducing the powder falling into the host. It is possible and possible to improve the mixing efficiency of the mixer shaft and the mixer arm.
The center line of the water pipe of the main cover shall be in the same vertical plane as the center line of the mixing shaft, and there shall be a direct spray nozzle above the Angle between the mixing arm and the mixing shaft. Because the Angle between the stirring arm and the rotating shaft is the easiest place to stick, the shaft is usually held from the root of the stirring arm. Also, it always takes time to add water.
After mixing and discharging, equipment operators should clean and flush the tank in time to ensure the removal of adhesive concrete. Equipment operators should periodically check the connection and sealing of the metering barrels in the metering system to check whether there is leakage. If there is leakage, remove it in time.
When you encounter the phenomenon of holding the axle in the process of using the concrete mixer, you must find out the specific reason in time, so as to solve it quickly, so as not to affect your normal work. More related questions come to http://www.zkzdsljbc.com website consultation!
