The invention discloses a pressurized water supplying system for circulation of a fountain solution of a printer. The system comprises a water storage tank, wherein one side of the water storage tank is connected with a water inlet pipe; a one-way water vale is arranged on the water inlet pipe, and the lower part of the other side of the water storage tank is connected with a water outlet pipe; an electromagnetic control valve is arranged on the water outlet pipe; a pressure meter is arranged outside the upper end of the water storage tank; a compression air bag is arranged in the water storage tank, a gap exists between the compression air bag and the inner wall of the water storage tank, and the compression air bag is connected with the compression pressure meter. The volume of the compression air bag is half of that of the water storage tank when the air pressure is equal to 0.1 mpa; a compression air bag air inflation and release valve is further arranged on a water storage tank body; a water discharge port is formed in the bottom of the water storage tank body. When the pressure in the water storage tank reaches 0.6 mpa, the electromagnetic control valve is opened, and pure water reaching the pressure standard is supplied to an infrared drying system or a uv (ultraviolet) drying system. The system is simple in structure, stable and reliable in work and convenient to maintain.
Description
technical field [0001] The invention relates to a printing press fountain solution circulation system, in particular to a printing press fountain solution circulation pressurized water supply system. Background technique [0002] At present, many parts of printing equipment in China have uv drying system, infrared drying system, and water-ink balance printing system. The above important parts all need to use water cooling and water-ink balance. In actual work, water will form scale in the circulation pipeline after passing through high temperature, making it difficult to cool down in the cooling cycle, and eventually lead to equipment damage. In response to this phenomenon, it was later changed to use pure water or make soft water with pure water, and then provide pure water to the cooling circuit of the infrared and UV drying system, so as to reduce the scale in the cooling circulation pipe. However, due to the limited water volume and water pressure produced by the pure w...
