Abstract

본 발명은 온수순환펌프의 펌프하우징에 있어서 펌프하우징의 내부면에 방청피막을 형성하는 것과 그 방청피막층을 코팅하는 방법에 관한 것으로서, 주철로 주조된 펌프하우징(1)에 있어서, 거칠면(3)으로 된 내부면(2)에 타르에폭시층(4)과 실록실렌층(5)을 이중으로 코팅하여서 된 것인바, 본 발명에 따른 펌프하우징(1)은 내부면(2)의 거칠면(3)에 타르에폭시층(4)과 실록실렌층(5)이 이중으로 코팅되어 있으므로 고압, 고속의 유체가 순환하더라도 부식, 침식되거나 녹이 발생하는 현상이 근본적으로 제거되고, 특히 주철면과는 흡착력이 우수하고 유체의 타격에 대한 저항성 및 내마모성이 우수한 실록실렌을 코팅하여 주철의 내부면을 보호함으로서 펌프하우징의 수명을 연장시키고 성능의 향상을 기대할 수 있다.The present invention relates to the formation of a rustproof coating on the inner surface of a pump housing in a pump housing of a hot water circulation pump and to a method of coating the rustproof coating layer, wherein the pump housing (1) cast from cast iron has a rough surface (3). The tar epoxy layer (4) and the siloxane layer (5) by coating a double coating on the inner surface 2, bar pump housing 1 according to the present invention is the rough surface (3) of the inner surface (2) Since the epoxy epoxy layer 4 and the siloxane layer 5 are double coated, the phenomenon of corrosion, erosion or rust is fundamentally eliminated even when the high-pressure and high-speed fluid circulates, and particularly, the adsorption power with the cast iron surface is excellent. By protecting the inner surface of cast iron by coating the siloxane with excellent resistance to the impact of the fluid and wear resistance, it is possible to extend the life of the pump housing and improve the performance.
