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.

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.
