A kind of hard rock tunnel boring machine water system

Abstract

The invention discloses a hard rock tunnel boring machine water system, which comprises a primary loop and a secondary loop for cooling a heating component, the primary loop for cooling the secondaryloop. The primary loop is provided internally with a cold water tank and a hot water tank separated from each other. Water inlet ends of first heat exchange assemblies are in communication with the cold water tank. Water outlet ends of the first heat exchange assemblies are in communication with the hot water tank. A communication pipeline is arranged between the cold water tank and the hot watertank. The water outlet ends of the first heat exchange assemblies are further connected with a water consuming assembly. The cold water tank and the hot water tank are separately arranged in the primary loop, the cooling water heated in the primary loop enters the hot water tank during operation and flows back to the communicated cold water tank after being cooled. In this way, the cooled coolingwater can be used repeatedly for cooling. At the same time, the high-temperature cooling water output by the heat exchange assemblies is supplied to the water consuming assembly. The cooling water ofthe consuming system is ensured to be high-temperature water, the low-temperature water circulating in the system is stored, the utilization rate of cooling water is increased, and the amount of waterconsumed by the water system is thus reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel boring equipment, and more specifically relates to a water system for a hard rock tunnel boring machine. Background technique [0002] Hard rock tunnel boring machine (abbreviated as TBM) is a high-end tunnel construction equipment that can adapt to complex strata and highly integrates multi-disciplinary technologies such as mechanics, electricity, hydraulics, light, control and materials. During the construction and excavation of TBM, various systems or components such as main drive motors, frequency converters, hydraulic systems and air compressors will generate heat, which will cause the temperature of the system or components to rise, affecting the normal operation of the system or components, thereby affecting the TBM In order to ensure the long-term and continuous operation of the TBM, a cooling system must be designed, that is, the TBM water system. [0003] At present, the TBM water system...
