1. The composition of the lifting hydraulic circuit. Double Scissor Car Lift is a lifting device that transports people or things vertically. It also refers to the equipment for vertical conveying in logistics systems such as factories and automatic warehouses. The lifting platform is often equipped with various plane conveying equipment as connecting devices for different height conveyor lines. It is generally driven by hydraulic pressure, so it is called a hydraulic lifting platform. In addition to being transported at different heights, the Double Level Scissor Car Lift for Wheel Alignment is widely used for installation and maintenance work at high altitudes.
2, Hydraulic Scissor Design Car Lift established the speed stiffness analysis formula of the lifting circuit. The flow rate into the hydraulic cylinder, that is, the flow rate through the one-way throttle valve, the throttle shape of the throttle valve and the viscosity of the hydraulic oil, and the AT inlet as the flow area of the throttle port (without throttle lift) flows into the hydraulic cylinder The flow rate, that is, the flow rate through the one-way throttle valve, the flow rate of the throttle valve, the shape of the throttle valve port, the viscosity of the hydraulic oil, and the like. When the area of the throttle valve is constant, the output speed of the hydraulic cylinder changes as the load changes. The effect of load change on speed is expressed by the speed stiffness T: as the load increases, the output speed of the Double Level Scissor Car Lift for Wheel Alignment actuator hydraulic cylinder is reduced by a negative number, in order to make the forward speed positive, A negative sign has been added to the formula.
