When using a hydraulic lift , the operator is most worried about the leakage of the hydraulic cylinder. Once the leakage occurs, the use of the hydraulic machine will be affected. Therefore , the sealing of the hydraulic cylinder of the hydraulic lift is the key to maintaining the hydraulic cylinder. Then you know which sealing devices are available for selection. The following Jinan Jinchuan lifting machinery gives you a detailed analysis of the problems, I hope to be helpful to everyone!
The importance of the hydraulic lifting machines sealing means
The hydraulic elevator sealing device mainly affects the working performance and efficiency of the hydraulic cylinder. Therefore, the basic requirement for the elevator sealing device is that it must have good sealing performance and reduce certain frictional resistance.
The gap seal in the hydraulic cylinder relies mainly on the small gap between the movements to prevent the hydraulic oil from leaking. In order to improve the sealing ability of the device, several small annular grooves are designed on the surface of the piston to increase the resistance of the rail-type elevator oil through the gap. In order to reduce the leakage of hydraulic oil and ensure the matching clearance of the moving parts, it is also necessary to improve the machining precision and surface roughness of the matching surface of the hydraulic cylinder.
It is well known that the hydraulic oil of aerial work platforms such as hydraulic lifts is the main driving force for starting the lifting equipment, and the hydraulic cylinders need to be strengthened as a key equipment for storing hydraulic oil. ( http:// )
Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.
