Hose pumps work on the principle of peristaltic action, where the hose is compressed in a wavelike manner to propel the fluid inside. This is achieved by using a rotor with pinch rollers that compress the hose against a stationary housing. As the rotor rotates, the pinch rollers sequentially compress the hose, creating a series of occlusion points that move along the hose, pushing the fluid forward. Hose Pumps for Slurry Grouting are a reliable and efficient choice for slurry grouting applications due to their abrasion resistance, ability to handle varying viscosities, self-priming capabilities, pulseless flow, and versatility. When selecting and maintaining a hose pump for slurry grouting, consider material compatibility, pump size and capacity, and maintenance requirements to ensure optimal performance.

Hose Peristaltic Type Concrete Pump Applications:
Mining Industry: Used for transferring mineral slurries, tailings, and other mining-related slurries.

A Hose Peristaltic Pump is an ideal solution for slurry transfer due to its unique design and operational characteristics. Slurries are mixtures of liquid and solid particles, often highly abrasive or corrosive, making them challenging to handle with conventional pump types.

A High Abrasion Resistance Peristaltic Hose Concrete Conveying Pump is a specialized piece of equipment designed to handle concrete or similar abrasive materials with minimal wear on the pump’s components. This type of pump is particularly useful for conveying concrete that contains coarse aggregates, which can be highly abrasive and challenging to move without causing significant damage to the pumping system. The pump uses a peristaltic hose as the conveying medium and conveys concrete through the peristaltic motion of the hose. During the working process, the hose is periodically compressed and released, thereby generating a peristaltic effect, pushing the concrete along the pipeline.

The working principle of the foam Concrete  hose pump for transfer foam concrete is mainly based on the principle of pressure delivery. It continuously delivers foam concrete along the pipeline through moving parts such as pistons or screws inside the pump body. During the pumping process, the pressure inside the pump body gradually increases, pushing the foam concrete forward until it reaches the designated construction location.

The working principle of the Foam Concrete Hose Squeeze Pump is based on the hose extrusion technology. During the pumping process, the rotor or pressure block in the pump head periodically squeezes the hose, so that the foam concrete in the hose is pushed out, forming a continuous pumping action. This pumping method is efficient and stable and is suitable for various complex construction environments.

Case analysis of dry and wet shotcrete machine for dam construction:
Dry and wet shotcrete machines have been widely used in many dam construction projects. For example, in the construction of a large hydropower station dam, a wet shotcrete machine was used for concrete spraying. By precisely controlling the spraying pressure and spraying angle, the flatness of the dam surface and the density of the concrete are ensured. At the same time, the efficient working performance of the wet shotcrete machine also greatly improves the construction efficiency and shortens the construction period.

There are many types of concrete shotcrete machines on sale. These devices are mainly used to continuously transport concrete along pipes and spray it onto the construction surface.

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.
