Unreasonable unloading time parameters
Since the automatic feeding mixer can not be installed in the silo level, so the industry basically has the function of time control. How to set the time parameters, load and unload time settings are actually very simple. When using, please set a short time, and then add slowly according to each suction position. When the material level reaches the suction time, one second can be subtracted. The discharge time is to ensure that the material is discharged again. This has two advantages: first, the material level is too high, and the damage to the filter element is particularly large. As a result, some of our customers can use the filter for two and a half years.
Second, each time the material is cleaned, the stop valve will not close when it is closed. Frequently operated seal valves will not switch five to six times, which is particularly dangerous.
Many of our projects use hand guns to pick up materials. In order to insert the material gun directly into the material pipe or the ton bag, the suction port of the material gun is compressed by the tight material, and the whole material is pulled apart by the strong negative pressure. The destructive power of the loader is very strong, and it is easy to block the pipeline. The correct way is that the material forms a certain gas-liquid mixing ratio between the suction port and the air, and flows into the feeder evenly under the push of the air flow. If the material backlog is too long, it can be very difficult. At this time, an oscillator is needed on the spray gun to destroy the condensed material.
In the actual operation of the automatic feeding mixer, some failures will inevitably occur. The barrier material is more serious. Therefore, I hope that after understanding the above methods of automatic feeding mixer, I can operate the equipment correctly and reasonably.
Don't overload. Always pay attention to working conditions. When the ambient temperature is higher than 25 ℃, the loading, transportation and unloading time shall not exceed 60 minutes. If the ambient temperature is lower than 25 ℃, the above time shall not exceed 90 minutes. The pressure of the hydraulic system is in accordance with the operation manual and cannot be adjusted at will. The quality and quantity of hydraulic oil must meet the original requirements.
After unloading at the construction site, the hose connected to the mixer is automatically used to clean the funnel, drainage funnel, drainage chute, etc. to remove the sludge and concrete attached to the vehicle body. On the way back to the mixing plant, pour 150-200 liters of water into the mixing tank to remove all concrete remaining on the tank walls and blades.
