Water supply system and cooling system

Abstract

The invention discloses a water supply system and a cooling system. The water supply system comprises a grinding water tank, a water supplementing pipeline, a buffer water tank and a heat exchanger, wherein a water outlet of the grinding water tank communicates with a grinding machine; an outlet of the water supplementing pipeline communicates with a water inlet of the grinding water tank; a water outlet of the buffer water tank communicates with an inlet of the water supplementing pipeline, and the buffer water tank is used for supplementing water to the grinding water tank; and the heat exchanger is provided with a first heat exchange pipeline and a second heat exchange pipeline which exchange heat with each other, an inlet of the first heat exchange pipeline communicates with a water source, an outlet of the first heat exchange pipeline communicates with a water inlet of the buffer water tank, and chilled water for cooling the cooling water circulates in the second heat exchange pipeline. According to the water supply system, the cooling water and the chilled water are subjected to heat exchange through the heat exchanger, the temperature of the cooling water can be greatly reduced, cooling of the grinding process is prevented from being influenced by cooling water exhaustion of the grinding water tank, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of substrate glass manufacturing and processing, in particular to a water supply system and a cooling system. Background technique [0002] In the process of liquid crystal glass substrate processing, an important step is to grind the substrate glass to eliminate edge defects. During the grinding process, the method of flushing the substrate glass and the grinding wheel is used to take away the heat generated during processing, so as to avoid the impact of excessive temperature on the quality of the edge of the substrate glass. However, the grinding water used now is at room temperature, and the temperature of the grinding water is not controlled, which will cause the following results: 1. The grinding quality of the edge of the substrate glass is unstable, and the process is difficult to control; 2. The temperature of the grinding water is too high Resulting in higher substrate glass grinding defects (drop...
