Power selection and characteristics of fixed hydraulic lifting platform

The scissor hydraulic lifting platform relies on the unfolding and folding of the scissor type support frame to lift the goods service platform. Its driving force is based on the telescopic type of the (t ō ng gu ò) hydraulic cylinder to promote the unfolding and folding of the scissors. It increases the efficiency of high-altitude operations and ensures greater safety. Because the telescopic speed of the hydraulic cylinder is determined by the total flow rate of the gasoline pump, the speed of the hydraulic cylinder is generally slower in the design scheme, with a speed of 200mm/minute, and the diameter of the inlet and outlet oil pipe connected to the hydraulic cylinder is 6mm. If the oil pipeline ruptures, the gear oil will only return through the 6mm inlet hole, so the descent speed is relatively slow, making it less likely to cause vandalism and damage

Scissor lift platform is a commonly used equipment for high-altitude operations. Its scissor mechanical system ensures high reliability of the lifting platform, spacious work service platform, and high load-bearing capacity, making the scope of high-altitude operations larger and suitable for many people to work separately. The driving force of the elevator is divided into 24

V. 220V or 380V switch power supply, diesel engine, using hydraulic sewage treatment plants from Spain and China. The cabinet countertop should be spliced with anti slip insulation layer, which has anti slip, insulation layer and safety. Please use it with peace of mind. Basic principle of lifting platform: Gear oil is generated by an axial piston pump with a certain working pressure. It enters the lower part of the hydraulic cylinder through an oil filter, a explosion-proof electromagnetic valve, an overflow valve, a one-way throttle valve, and a static balance valve, causing the piston rod of the hydraulic cylinder to move upwards and lift the suspended object. The oil returning from the upper part of the hydraulic cylinder returns to the car fuel tank through a explosion-proof electromagnetic valve. Its rated working pressure is adjusted according to the speed control valve, and the reading value of the pressure gauge is observed based on the pressure gauge.

The piston rod of the hydraulic cylinder moves downwards for fitness (i.e. descending the suspended object). The gear oil enters the upper part of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil below the hydraulic cylinder returns to the car fuel tank through the static balance valve, one-way throttle valve, overflow valve, and explosion-proof electromagnetic directional valve. To ensure stable descent of the suspended object, the braking system can be trusted. A static balance valve is installed on the return oil passage to balance the control circuit and maintain the working pressure, so that the descent speed will not be affected by the suspended object. The total flow rate is adjusted by the overflow valve to control the speed of the elevator.
