Scissor lift working principle
The hydraulic lifting device controls the direction of movement of the two cylinders. In China, this technology has successfully applied the reliability and durability tests of gas control systems since the late 1980s. In addition, it is necessary to examine the advantages and disadvantages of various control algorithms and control strategies for computer control systems, and provide the basis for actual improvement to obtain the best improvement effect. Therefore, a large-scale hydraulic synchronous lifting test rig was designed. The test rigs included a total of 3 parts
Hydraulic synchronous lifting test bench. Hydraulic loading test bench and computer control system. This article only describes the function of hydraulic synchronous lifting test rig and its debugging test. When the work piece is carried on the elevating work table, a hydraulic cylinder is required to provide the driving force, that is, the hydraulic cylinder outputs energy to the work table; and when the work piece carried on the work bench descends, its potential energy is released.
It is necessary to carry out simulation test of hydraulic synchronous lifting equipment before the actual implementation of the hydraulic lift. It includes: synchronous lifting cylinder, hydraulic pump station, jack and other loading test and pressure test, and sensing detection system.
