Problems solved by technology

[0004] However, in this system, once the water temperature of the open system reaches the set upper limit, it can only be shut down and the water is released, and cold water is refilled in the industrial water tank of the open system
In the harsh construction environment of the roadheader, this water change process often needs to be started. The water change project is relatively large and inconvenient to implement. It is not conducive to the safe and reliable operation of the roadheader, and it is not in line with the purpose of energy conservation and environmental protection.

Abstract

The invention discloses a cooling system. The cooling system comprises an outer circulating system and an inner circulating system used for cooling heating parts. A primary water tank cooling loop isarranged in the outer circulating system and comprises a cooling tower, a primary water tank and a first cooler. The water flowing from the cooling tower can flow through a refrigerant passage of theprimary water tank and a refrigerant passage of the first cooler in sequence and then flows back to the cooling tower. A first power device used for driving the water to flow is arranged in the primary water tank cooling loop. A heating medium passage of the first cooler is connected with the interior of the inner circulating system. The cooling system can reduce the temperature of the water in the primary water tank to the normal working range through the cooling tower, there is no need to replace the water in the primary water tank by opening a sluice to guarantee the cooling capacity of theouter circulating system in the prior art, and the cooling capacity of the outer circulating system can be adjusted more conveniently. The invention further discloses a boring machine including the cooling system, and the cooling capacity of the outer circulating system can be adjusted more conveniently.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a cooling system. In addition, the present invention also relates to a boring machine comprising the above-mentioned cooling system. Background technique [0002] In tunneling machines such as shield machines, a cooling system is usually provided to cool the equipment. During the normal excavation of the roadheader, the internal hydraulic system, the main drive part and the electrical components in the power distribution cabinet often generate a lot of heat, which will increase the temperature of the motor, pump and other equipment and the environment in the tunnel. Once the temperature is too high , will cause equipment damage and bring personal danger, so a cooling system must be installed to cool it in time. [0003] The current cooling system usually includes an internal circulation system and an external circulation system. The internal circulation system is ...
