Problems solved by technology

At present, the cylinder barrel of the lifting cylinder used in the corrosion-resistant scene uses C22 (C22 is a high-quality carbon structural steel, high-manganese and low-carbon infiltration steel, and its performance is similar to 15Mn steel), C276 (a nickel-chromium containing tungsten -Molybdenum alloy, with extremely low silicon-carbon content, considered as a universal anti-corrosion alloy), 904L (super austenitic stainless steel) and other special materials, the cost is extremely high

Embodiment

[0018] See attached figure 1 , figure 2 As shown, a corrosion-resistant lifting cylinder in this embodiment includes a cylinder 1, the upper end of the cylinder 1 is connected to a gland 2, and the gland 2 and the cylinder 1 are locked by bolts. The cylinder 1 is provided with a piston 3 and a plunger rod 4 , the lower end of the plunger rod 4 is connected to the piston 3 , and the upper end of the plunger rod 4 is inserted on the gland 2 . In order to reduce the cost of the oil cylinder, the cylinder barrel 1 includes a thin-walled tube, and the outer surface of the thin-walled tube is covered with an outer sleeve made of 304 material (304 stainless steel). The above-mentioned thin-walled tube is coated with 304 material (304 stainless steel), which does not reduce the corrosion resistance effect and strength. combine image 3 As mentioned above, the outer casing 6 is realized by welding the three-section casing and then processing, such as using: C276 / C22 pipe material. ...

Abstract

The invention discloses a corrosion-resistant lifting oil cylinder, and relates to an execution machine doing one-way motion in a hydraulic system. The oil cylinder comprises a cylinder barrel, the upper end of the cylinder barrel is connected with a gland, a piston and a plunger rod are arranged in the cylinder barrel, the lower end of the plunger rod is connected with the piston, and the upper end of the plunger rod is arranged on the gland in a penetrating manner. The cylinder barrel comprises a thin-walled pipe, and the outer surface of the thin-walled pipe is coated with an outer sleeve made of 304 materials. The thin-walled pipe is coated with the 304 materials, so that the cost is greatly reduced, the corrosion resistance effect is not reduced, and the cost is greatly reduced on thepremise that the strength is not reduced.

Description

technical field [0001] The invention relates to an executive machine for unidirectional movement in a hydraulic system, in particular to a corrosion-resistant lifting oil cylinder. Background technique [0002] The lifting cylinder is an executive mechanism for one-way movement in the hydraulic system, and the retraction is mainly performed by its own weight or other actuators. At present, the cylinder barrel of the lifting cylinder used in the corrosion-resistant scene uses C22 (C22 is a high-quality carbon structural steel, high-manganese and low-carbon infiltration steel, and its performance is similar to 15Mn steel), C276 (a nickel-chromium containing tungsten -Molybdenum alloy, with extremely low silicon-carbon content, considered as a universal anti-corrosion alloy), 904L (super austenitic stainless steel) and other special materials, the cost is extremely high. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the presen...
