Corrosion-resistant water tank structure with bush

Abstract

The invention relates to the technical field of water cylinders of hydraulic pressure expanding mills, in particular to a corrosion-resistant water cylinder structure with bushings, which comprises a mold locking main body, a plurality of cylinder barrels are arranged on the top surface of the mold locking main body in a linear equidistant structure, cylinder bottoms are arranged on the bottom surfaces of the cylinder barrels, cylinder covers are arranged on the top surfaces of the cylinder barrels, and the cylinder barrel bushings are in clearance fit with the interiors of the cylinder barrels. A cylinder bottom and a cylinder barrel are fixedly installed through an inner hexagon bolt A, a piston is arranged on a piston rod in a sleeving mode, then a semi-ring is installed in a wide groove in the lower end of the piston rod, the semi-ring is sleeved with a shaft sleeve from bottom to top, and then a dust seal, a wear-resisting ring B, a step seal and rubber clamping cloth are sequentially installed on a cylinder cover. The cylinder cover and the flange are fixedly connected with the cylinder barrel through the inside hexagonal bolts B, installation of the piston and the piston rod is completed, the hydraulic cylinder can be used in the seaside saline-alkali soil, corrosion and abrasion are avoided, the service life is prolonged, the use cost is reduced, maintenance and replacement are more convenient, leakproofness is good, inner leakage is avoided, and the use effect is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of water cylinders for hydraulic diameter expanders, in particular to a corrosion-resistant water cylinder structure with a liner. Background technique [0002] The diameter expansion machine belongs to the straight seam metal welded pipe shaping equipment. It uses a cone expansion head to expand in the steel pipe to eliminate the forming pressure and welding stress of the steel pipe, and to ensure that the full length of the straight seam welded steel pipe is the same true diameter. The equipment consists of a trolley, an expander, a working sleeve, a fixed seat, an oil cylinder, a lubrication station, a bench, a hydraulic station, and an electric control system. The expander is set on the trolley. The expander is connected to the oil cylinder by the working sleeve. The expander is composed of an expanding head, an expanding block, a guide plate, and a tie rod. Large-scale equipment that ensures the shape ...

Problems solved by technology

[0004] In the prior art, the factory building is usually built on the saline-alkali site by the sea, and the anti-leakage measures for the pool are not effective, resulting in a high salt content in the pool, and the water is highly corrosive. The inner wall of the barrel is generally corroded and worn, densely covered with pits, serious internal leakage, and unusable
