Title:
HYDRAULIC CYLINDER DEVICE WITH WATER-SAVING WATER-COOLING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/199275
Kind Code:
A1
Abstract:
A hydraulic cylinder device with a water-cooling structure, comprising a hydraulic cylinder (1), an asbestos column (2), a water inlet pipe (3), a water outlet pipe (4) and a flange plate (5). The asbestos column (2) is fixedly arranged at the top of a cylinder body (11) of the hydraulic cylinder; the top end of the asbestos column (2) is connected to a water inlet pipe (3), and the bottom of the cylinder body(11) is connected to the flange plate (5); a water receiving groove (51) is formed in the flange plate (5); the bottom face of the water receiving groove (51) is obliquely arranged, and the lowest point of the bottom face of the water receiving groove (51) is connected to a water outlet pipe (4). The asbestos column (2) is made of asbestos cloth. Cooling water flows into the asbestos column (2) through the water inlet pipe (3); the cooling water flows out from the asbestos column (2), then flows out from the top of the cylinder body of the hydraulic cylinder (1) and cools the hydraulic cylinder (1); and the flowing cooling water flows into the water receiving groove (51) in the flange plate (5) and then flows out from the water outlet pipe (4), so that the temperature of the hydraulic cylinder (1) is reduced, the service life of a hydraulic system is prolonged, the troubleshooting time is shortened, and the production benefit is improved.
