Large hydraulic damper with oil leakage warning function

Abstract

The invention relates to the technical field of hydraulic dampers, in particular to a large hydraulic damper with an oil leakage warning function, which comprises a hydraulic shell and is characterized in that an inner hydraulic cavity is formed in the top surface of the hydraulic shell, hydraulic oil is filled in the inner hydraulic cavity, a top shell is fixedly arranged on the top surface of the hydraulic shell, and a top cavity is formed in the bottom surface of the top shell; a surface measuring ring is fixedly arranged in the inner wall of the top cavity, a fixing disc is fixedly arranged on the inner wall of the top cavity, compensation oil is arranged on the top face of the fixing disc, a sealing cavity is formed in the bottom face of the hydraulic shell, a sealing gasket is arranged in the sealing cavity in a sliding mode, and two sealing screw rods which are symmetrical left and right are rotationally arranged on the bottom face of the hydraulic shell. According to the oil leakage detection device, the oil leakage phenomenon is detected according to descending of the oil level of hydraulic oil, alarm lamps are installed on the two sets of detection devices, and therefore a worker can rapidly obtain an oil leakage point.

Description

technical field [0001] The invention relates to the technical field of hydraulic dampers, in particular to a large hydraulic damper with an oil leakage warning function. Background technique [0002] The damper is a device that provides movement resistance and consumes movement energy. When the hydraulic damper is working, the gasket is continuously worn, and after a long period of use, the gasket gradually ages, which makes the gasket seal invalid, resulting in Hydraulic oil leaks from the damper, and the shell of the hydraulic damper is generally in direct contact with the external environment, so the shell of the damper may be corroded, resulting in cracks on the shell of the damper, and cracks may penetrate the shell of the damper in severe cases. As a result, the hydraulic oil leaks from the damper, and when the hydraulic oil in the damper decreases, the damping effect of the damper will also decrease, and may even cause the entire damper to fail; [0003] Moreover, wh...

[0002] The damper is a device that provides movement resistance and consumes movement energy. When the hydraulic damper is working, the gasket is continuously worn, and after a long period of use, the gasket gradually ages, which makes the gasket seal invalid, resulting in Hydraulic oil leaks from the damper, and the shell of the hydraulic damper is generally in direct contact with the external environment, so the shell of the damper may be corroded, resulting in cracks on the shell of the damper, and cracks may penetrate the shell of the damper in severe cases. As a result, the hydraulic oil leaks from the damper, and when the hydraulic oil in the damper decreases, the damping effect of the damper will also decrease, and may even cause the entire damper to fail;

[0003] Moreover, when the damper leaks oil, the staff generally checks the entire damper step by step until the leak point is found, which takes a long time and is inefficient
