Many customers are not very familiar with the working principle of the hydraulic system of the lifting platform . Today, the Jinan Dragon Casting Factory will introduce some relevant knowledge about the working principle of the hydraulic system of the lifting platform.
Brief description of the working principle of the lifting platform hydraulic system: The working pressure of the hydraulic system is 16mpa, which mainly includes hydraulic pumping stations, emergency pump oil circuits, platform lifting oil circuits, and outrigger telescopic oil circuits. The oil pump station is an engine-driven oil pump, which supplies oil through control valves and pipeline actuators (lift cylinders and outrigger cylinders); the emergency pump oil circuit is when the engine fails, the vehicle has no power source, and an electric emergency engine is required. After the failure, the vehicle has no power source, and the platform needs to be lowered by an electric emergency pump to unload the cargo. The legs are pulled away and the car is towed away; the lifting oil path is the platform and the cargo through two lifting cylinders in the loading and unloading state Lift and fall. The bracket is pulled up by a chain using a vertical cylinder arrangement. The outrigger telescopic oil circuit consists of four outrigger cylinders connected in parallel. When the cargo is loaded and unloaded, the outriggers are extended and retracted.
We all know that the lifting platform has a clever structure design, a high safety factor, and a high degree of machinery, which reduces the labor intensity for people. In the design of the lifting system, the hydraulic and electrical control components that are already mature in domestic engineering machinery are applied. The reliability and maintainability meet the design requirements.
