HOT WATER BOILER INCLUDING PUMP HOUSING HAVING VIBRATION AND NOISE REDUCING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a hot water boiler including a pump housing having a vibration and noise reducing structure reducing noise by absorbing vibration generated during operation of a pump and basically cutting off transmission of vibration to other components of the boiler joined to the pump housing, and improving economical efficiency by preventing loosening or uncoupling of each component composing the boiler due to vibration and saving work time and costs necessary for maintenance of the boiler. SOLUTION: The hot water boiler comprises a boiler body having a mounting part; a drive; an impeller linked with the drive; and the pump housing including an outer covering surrounding the drive, a mounting bracket disposed in an upper part of the outer covering and connected to the mounting part of the boiler body, and a cover disposed in a lower part of the outer covering and having an inflow part and a discharge part, and connected to the mounting part of the boiler body. The outer covering of the housing comprises a vibration damping object. COPYRIGHT: (C)2011,JPO&INPIT
