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.
In dry shotcrete, liquid accelerators react with cement in the dry mix to quickly form a hardened structure. Since dry shotcrete is a mixture of dry mix and water and then sprayed onto the construction surface through a nozzle, the addition of liquid accelerators requires strict control of the mix ratio and mixing uniformity. In wet shotcrete, the mechanism of action of liquid accelerator is similar to that of dry shotcrete, but the construction method and mixing process are different. Wet shotcrete is to spray the pre-mixed wet mix onto the construction surface through a nozzle, so the addition and mixing process of liquid accelerator needs to be completed during the wet mix preparation stage.
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.
The accelerator metering pump is a key component in the shotcrete machine. It is responsible for accurately metering and delivering concrete accelerator. Accelerators can significantly increase the early strength of concrete, speed up construction, and improve the physical properties of concrete. Through precise metering and delivery, the accelerator metering pump ensures uniform distribution of concrete accelerator in shotcrete, thereby improving construction quality and efficiency.
Accelerators for shotcrete machine are often used to improve the working efficiency of shotcrete machines by accelerating the spraying speed of concrete so that the concrete can be covered and cured on the working surface more quickly. This can not only shorten the construction time, but also improve the construction quality and efficiency.
Accelerator dosage systems play a crucial role in optimizing shotcrete applications by ensuring precise control over concrete setting times and early strength development.
In shotcrete systems, the accelerator dosage pump plays a critical role in precisely metering and injecting accelerators into the concrete mix. The choice between dry and wet accelerator dosing depends on the specific requirements of the project and the properties of the accelerator used.
Shotcrete machines with accelerator systems integrate advanced dosing technology with robust shotcrete equipment to deliver efficient and high-quality concrete spraying applications. They are essential for achieving rapid construction timelines and ensuring durable concrete structures in various construction and repair projects.
