A water supply system for boiler which uses the vapor pressure and the micro small capacity pump

摘要

PURPOSE: A water supply device for a boiler using a micro pump and steam pressure is provided to improve thermal efficiency by supplying the water of a supplement water tank in high temperature. CONSTITUTION: A water supply device for a boiler using a micro pump and steam pressure comprises a boiling tank(10), a water supply pressure tank(20), a steam pressure supply pipe(30) and a micro compression pump(40). The boiling tank produces steam according to the operation of an electric heater(11). A water level sensor(12) for sensing a water level is installed in the boiling tank. The water supply pressure tank is installed to be connected with the boiling tank. A water level sensor(22) is installed inside of the water supply pressure tank. The steam pressure supply pipe is mounted on top of the boiler tank and the water supply pressure tank. A steam pressure supply control valve(31) is installed on the steam pressure supply pipe. The micro compression pump is formed on one side of a water pipe(23) connected with the water supply pressure tank. A water supplying pipe(25) combined in the other side of the micro compression pump is connected with the boiler tank to pass water through.
