Magnetic isolation and heat dissipation protection cover of hydraulic cylinder and magnetic isolation and heat dissipation method thereof

Abstract

The invention provides a magnetic isolation and heat dissipation protection cover of a hydraulic cover and a magnetic isolation and heat dissipation method. The magnetic isolation and heat dissipationprotection cover comprises a barrel and a cooler. The barrel is arranged on the hydraulic cylinder in a covering mode. An end plate is mounted at the bottom end of the barrel. A mounting hole allowing a piston rod of the hydraulic cylinder to penetrate through is formed in the top end of the barrel. A conductive fiber layer covers the outer wall of the barrel. A cooling cavity is formed in a barrel body of the barrel. A mixed solution for occurrence of reversible reaction is stored in the cooling cavity. Grounding conducting wires are fixedly arranged on the end plate. The cooler communicateswith the cooling cavity and is used for performing heat exchanging and cooling on the mixed solution. The cooler comprises a water inlet pipe communicating with an outlet and a water outlet pipe communicating with an inlet. A first suction device is arranged between the water inlet pipe and the outlet, and a second suction device is arranged between the water outlet pipe and the inlet. The barrelis an aluminum alloy barrel. The end plate is an aluminum alloy end plate. The first suction device and the second suction device can be used for sucking liquid and / or gas. By means of the magnetic isolation and heat dissipation protection cover, magnetic isolation and heat dissipation for the hydraulic cylinder can be achieved well.

Description

technical field [0001] The invention relates to the field of hydraulic cylinders, in particular to a magnetic isolation and heat dissipation protection cover for a hydraulic cylinder and a magnetic isolation and heat dissipation method thereof. Background technique [0002] The Chinese invention patent with the announcement number CN103452956B and the announcement date of February 10, 2016 discloses "a hydraulic cylinder", including: a cylinder, a piston, a piston rod and an end cover. The piston is located inside the cylinder and divides the cylinder into In the first chamber and the second chamber, the piston rod is located on one side of the piston and is fixedly connected with the piston, the end cover is fixedly connected with the open end of the cylinder barrel, and the piston rod protrudes through the end cover, wherein a limit device is installed on the piston, The limiting device includes a first one-way valve, a second one-way valve and a first push rod, the oil ou...

Problems solved by technology

However, as a supporting component, hydraulic cylinders often work in a magnetic field environment. The hydraulic cylinder will generate eddy currents in the magnetic field environment, which will cause the hydraulic cylinder to heat up, causing the seals in the hydraulic cylinder to fail after working in a high temperature environment for a long time, resulting in the life of the hydraulic cylinder shorten
