Many products will now pay attention to the principle, then the lift is no exception, following on from the Xiaobian to introduce the principle of hydraulic lifts. Hydraulic lift is a support mechanism by walking, electrical control equipment, hydraulic institutions. Hydraulic oil pump blade shape is the result of a certain pressure, and then into the lower end of the hydraulic cylinder through the throttle valve, filter, check valve, the liquid piston moves upward, so as to enhance the weight, its rated pressure through the overflow flow adjustment valve, pressure gauge can be observed through the pressure of performance in order to read out the value. Hydraulic lift before the implementation of the project must be synchronized hydraulic lifting device simulation. Include: hydraulic pump station, jack, sync lift cylinders and other load test and pressure test, and sensor detection systems. Hydraulic lift is a scissor lift, folding arm lift replacement product. It can be widely used in railway stations, docks, airports, public buildings and other places, facade renovation and decoration used a lot, especially to be able to perform aerial work across the obstacle. The above is from a hydraulic lift Xiaobian to introduce the principles of knowledge, you know it? ? ?
