The key to hydraulic lifting platform is to gradually realize the function of the elevator based on the working pressure transmission system of gear oil. Its scissor mechanical system ensures high reliability of the lifting platform. The spacious working service platform and high load-bearing capacity make the high-altitude operation scope larger and suitable for many people to work separately. It increases the efficiency of high-altitude operations and ensures safety (ensuring effectiveness).
Most models use a single-sided oil cylinder, which rises. The blade pump outputs high-pressure oil through a series of control valves and pipelines that enter the lower part of the oil cylinder, promoting the rise of the oil cylinder and lifting the service platform; When descending, the vane pump terminates and the control valve opens the oil discharge control circuit. The service platform slowly descends under the weight effect, and the hydraulic oil in the cylinder is squeezed and discharged! Generally, the descent of the lifting platform relies on its own net weight as the driving force, which presses out the steam under the piston rod and gradually descends. Therefore, the rate at which the oil under the piston rod is discharged determines the speed of descent. Generally, there are various valves on the inlet and outlet pipelines under the oil cylinder, among which there is an electromagnetic induction throttle valve (which is essentially a combination of a relay and a throttle valve). Its function is to operate the throttle valve through the relay, and the throttle valve is used to control the size of the remaining oil in and out of the water pipe. Generally, there is a knob on the valve body of the throttle valve to adjust the remaining oil, similar to a sound knob or a faucet knob. Therefore, you can adjust the descent rate by adjusting the knob on the throttle valve.
