Title: HIGH-PRESSURE LARGE-CAPACITY WATER SUPPLY APPARATUS
Abstract:
Disclosed is a high-pressure large-capacity water supply apparatus which is configured to: continuously discharge water toward an upper discharge pipe and a lower discharge pipe with a single crankshaft rotation and a single stroke reciprocating motion of a piston corresponding thereto, allow a pair of cylinders to be interlocked with each other by means of a crankshaft module to discharge the water, smoothly discharge high-pressure, large-capacity water through a pair of discharge ports, form top and bottom holes of a piston head of a transfer cylinder and top and bottom ring grooves corresponding thereto so as to form a water film between a head and an inner wall of a transfer cylinder main body by movement of the piston, prevent damages of the head and the inner wall to improve abrasion resistance, prevent the piston from leaning to a left side or a right side by the water film so as to prevent the piston from deviating from the center of the transfer cylinder main body, thereby preventing damages of the head and the inner wall, and also minimize water pressure leaking into a space between the head and the inner wall of the transfer cylinder main body.
