Accelerator metering pump for shotcrete
2024-10-15 15:26:14
Pneumatic drive accelerator metering pump for shotcrete machine is mainly composed of pneumatic drive device, pumping device, metering device and control system. The pneumatic drive device provides power, the pumping device realizes the delivery of accelerator, the metering device ensures the precise control of the delivery amount, and the control system is responsible for the operation and adjustment of the entire system.
1. Pneumatic drive device
Using compressed air as the power source, it has the advantages of simple structure, convenient operation and low maintenance cost.
By controlling the flow and pressure of compressed air, the operating speed and delivery amount of the pumping device can be adjusted.
2. Pumping device
Responsible for extracting the accelerator from the storage container and delivering it to the nozzle of the shotcrete machine.
Usually made of wear-resistant and corrosion-resistant materials to ensure that the accelerator will not be contaminated or lost during the delivery process.
A reasonable flow channel structure is designed to reduce the resistance and energy consumption during the delivery process.
3. Metering device
Accurately measure and record the amount of accelerator delivered to ensure that the amount of accelerator sprayed each time meets the process requirements.
High-precision measuring elements such as electronic scales and flow meters can be used, and they are equipped with advanced control systems for data processing and display.
The metering device also has automatic calibration and fault alarm functions to ensure the accuracy of measurement and the reliability of the system.
4. Control system
Responsible for the operation control and monitoring of the entire system.
The flow and pressure of the pneumatic drive device and the operating speed of the pumping device can be automatically adjusted according to the set parameters.
It also has fault diagnosis and alarm functions, which can promptly detect and handle abnormal conditions in the system.
The accelerator metering pump system for shotcrete machine is widely used in shotcrete operations in underground projects such as tunnels, subways, and mines. By using this system, accurate metering and stable delivery of accelerators can be achieved, thereby improving the quality and efficiency of shotcrete operations. At the same time, the system also has the advantages of simple operation, low maintenance cost, energy saving and environmental protection, which helps to reduce construction costs and environmental impact.
