TBM Used Chain Peristaltic Pump
The chain peristaltic pump used in TBM (Tunnel Boring Machine) is a special equipment designed for handling high-viscosity, solid-particle fluids under extreme conditions. This type of pump is used to transport materials such as mud and mortar during TBM construction to ensure smooth soil discharge and lining operations during tunnel excavation.
Application Cases
Slurry Shield Machine: Used to transport mud generated during excavation from the cutterhead to ground processing facilities.
Earth Pressure Balance Shield Machine: Used to transport mortar to ensure pressure balance on the excavation face and prevent surface settlement.
Hard Rock TBM: Used to transport rock debris and mud generated after drilling and blasting to ensure cleanliness and construction progress inside the tunnel.
The chain peristaltic pump used in TBM (full-face rock tunnel boring machine) is a special type of peristaltic pump, which combines the principle of peristaltic pump with the advantages of chain transmission mechanism.
1. Working principle of TBM Used Chain Peristaltic Pump
The working principle of chain peristaltic pump is based on peristaltic effect, but it is different from traditional peristaltic pump. It uses chain transmission mechanism to drive rollers or pressure blocks in the pump head, which move along the outer wall of the hose or pump tube and squeeze the hose sequentially, thereby pushing the fluid in the hose to flow forward. The chain transmission mechanism ensures the uniform distribution and stable movement of the rollers or pressure blocks, thereby achieving continuous and stable delivery of the fluid.
2. Structure of TBM Used Chain Peristaltic Pump
The chain peristaltic pump used by TBM is mainly composed of the following components:
Pump body: The pump body is the outer shell of the pump, which is used to accommodate the hose and transmission mechanism.
Hose: The hose is the core component of the pump, which is responsible for conveying fluid during the squeezing and release process. The hose is usually made of elastic material with good wear resistance and corrosion resistance.
Chain drive mechanism: The chain drive mechanism consists of a chain, rollers or pressure blocks, etc., which are used to drive the rollers or pressure blocks to move along the outer wall of the hose.
Drive device: The drive device is usually an electric motor or a hydraulic motor, which is used to provide the power required by the chain drive mechanism.
3. Features and advantages of TBM Used Chain Peristaltic Pump
Efficient and stable: The chain peristaltic pump adopts a chain drive mechanism to ensure the uniform distribution and stable movement of the rollers or pressure blocks, thereby achieving continuous and stable delivery of the fluid.
Strong adaptability: The pump can adapt to different types of fluids, including high-viscosity fluids, corrosive fluids, and fluids containing particles.
Simple maintenance: Since there are no complex mechanical parts inside the pump body, maintenance is relatively simple. It is only necessary to replace the hose regularly and check the wear of the drive mechanism.
Wear resistance: The chain drive mechanism has high wear resistance and can operate stably for a long time.
4. Application fields of TBM Used Chain Peristaltic Pump
The chain peristaltic pump used by TBM has a wide range of applications in many fields, including but not limited to:
Tunnel excavation: In the process of tunnel excavation, the chain peristaltic pump can be used to transport construction materials such as concrete and mortar, as well as auxiliary fluids such as cooling water and lubricating oil.
Mining: In mining, the pump can be used to transport solid granular materials such as ore and coal powder, as well as liquid materials such as slurry and water.
Water conservancy projects: In water conservancy projects, chain peristaltic pumps can be used to transport fluids such as water and mud, as well as agricultural irrigation systems such as irrigation and drainage.
In summary, the chain peristaltic pump used by TBM has the characteristics of high efficiency and stability, strong adaptability, and simple maintenance, and is widely used in many fields. During use, it is necessary to pay attention to the selection of suitable hoses, regular inspection of the transmission mechanism, cleaning and maintenance, and safe operation.
