1. Process introduction

Tunnel machine is a kind of mechanical equipment used for tunnel construction, such as shield machine, tunneling machine, supporting equipment and loading equipment, mainly including shield machine and roadheader machine for temperature control; shield machine is a special tunneling machine whose cutter and shield body are made of high strength steel, so cooling machine needs to avoid overheating deformation or burn of cutter plate and shield body. In addition, the chiller can cool the hydraulic system and electrical system of the shield machine to ensure the normal operation of the equipment; the boring machine is a mechanical equipment to break rock and soil and dig into tunnels. In the process of tunneling, a lot of heat will be generated, so the water cooler needs to be used for cooling. The chiller can take away the heat generated inside the roadheader to avoid overheating of the equipment, and also improve the stability and service life of the equipment.

2. Characteristics of the temperature control equipment of the tunnel machine

Efficient cooling:

The chiller takes away the heat generated by the equipment through the circulating cooling water, which effectively reduces the working temperature of the equipment and ensures the normal operation of the equipment.

Stable operation:

By precisely controlling the temperature, the chiller can avoid overheating or overcooling of the equipment, ensuring the stable operation of the equipment and improving the production efficiency.

Extend the life of the equipment:

The chiller can effectively reduce the working temperature of the equipment, reduce the aging, wear and other problems caused by overheating, and prolong the service life of the equipment.

Energy conservation and environment protection:

The chiller reduces the consumption of water and the discharge of waste water by recycling the cooling water, which meets the requirements of energy saving and environmental protection.
