Description

Technical Field

[0001] The utility model relates to water supply equipment, in particular to a modular circulating water supply device. Background Art

[0002] During the operation of some mechanical equipment, a circulating water supply device is often required. There are some problems with this conventional circulating water supply device: when the number of cycles of the circulating water increases, the quality of the circulating water gradually decreases. When the water source quality drops to a certain condition, the water source needs to be replaced, generally based on a cycle of circulation time, for example, once a month. When replacing the water source, the mechanical equipment has to stop running because it cannot receive water; when the mechanical equipment is running, it generates heat. When the water supply device supplies water to the mechanical equipment, the temperature of the circulating water will rise. Therefore, a cooling device is installed on the circulating water supply pipe. However, when dealing with mechanical equipment with low heat generation or intermittent operation conditions, installing a cooling device will cause the cost of the circulating water supply device to increase sharply; this kind of circulating water supply device is generally large in size and heavy. When in a situation where the placement position of the circulating water supply device has to be changed frequently, due to its large size and being a whole, the adjustment process is extremely inconvenient and the flexibility of use is poor. Therefore, it is necessary to optimize the structure of this circulating water supply device to overcome the above defects. Summary of the Utility Model
