The pneumatic accelerated metering pump system usually consists of a pump body, a pneumatic servo device, a control system, etc. It uses compressed air as a power source and adjusts the stroke length (or flow rate) of the pump through a pneumatic servo device, thereby achieving accurate metering and accelerated delivery of liquids.
The main components of liquid shotcrete accelerators usually include alkaline substances (such as sodium hydroxide, potassium hydroxide, etc.), inorganic salts (such as aluminates, silicates, etc.) and some other organic or inorganic compounds as additives and regulators. These components are precisely proportioned and mixed during the preparation process to ensure that the performance of the accelerator is stable and meets the construction requirements.
Liquid accelerator for shotcrete is a chemical additive specially used in shotcrete construction. Shotcrete liquid accelerator is a liquid chemical agent that can significantly accelerate the setting and hardening process of shotcrete. It mainly reacts chemically with the cement component in concrete to quickly form a hardened structure, thereby improving the early strength and durability of shotcrete.
An air-driven accelerator metering pump system for shotcrete is specifically designed to meter and inject chemical accelerators into the shotcrete mix during the spraying process. This system uses compressed air as the driving force, making it ideal for environments where electrical systems may not be suitable or where compressed air is already available, such as in tunnels, underground mines, and other hazardous work environments. The accelerator, a key additive in shotcrete, helps to reduce setting time and increase early strength development, which is critical in high-pressure environments.
An additive dosing pump for a shotcrete machine is an essential component used to accurately meter and inject chemical additives (such as accelerators, retarders, plasticizers, or other admixtures) into the concrete mix during the shotcrete process. These additives can modify the setting time, workability, strength, or other characteristics of the shotcrete, making the pump a critical tool in tailoring the mix to the specific requirements of a project.
