anti-freezingusing system for water-lubrication type air compressor

摘要

The present invention relates to an anti-freezing system of a water-lubricated air compressor. The anti-freezing system prevents the lubricating water of a water-lubricated air compressor, which uses the water instead of oil to cool the heat generated during the operation of the compressor and enhance the lubricating, sealing, and compressing performance, from being frozen or boiled to overflow a container. More specifically, the anti-freezing system includes a water-overflow prevention valve and a bypass line to prevent the water from overflowing. A heater is additionally installed to prevent the lubricating water from being frozen.
