Summary: | PURPOSE:To provide an oil feed pipe structure wherein an oil tank is prevented from the generation of vibration resonance noise of an electromagnetic pump only through variation of the size and the shape of a pipe, in an oil feed pipe route in a system of a petroleum hot water boiler and an oil tank. CONSTITUTION:A metallic connection pipe 3 running between the primary side of an electromagnetic pump 2 incorporated in a petroleum hot water boiler and an external metallic oil feed pipe 5 forms a metallic piping having diameter lower than that of the external metallic oil feed pipe 5 and is formed in a loop-form shape or a U-shape. Vibration resonance noise of an oil tank 6 generated owing to vibration of the electromagnetic pump 2 cushion in the middle of an oil feed route is prevented from the generation so that vibration of the electromagnetic pump 2 is not propagated to the oil tank 6. |
