Description

Slow pressure hydraulic control system with hydraulic energy storage and its implementation method

technical field

The invention relates to the technical field of hydraulic systems, in particular to a pressure-relieving hydraulic control system with hydraulic energy storage and an implementation method thereof.

Background technique

The role of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. The main function of the hydraulic transmission system is to transmit power and motion. The hydraulic control system must make the output of the hydraulic system meet specific performance requirements. The hydraulic system generally refers to the hydraulic transmission system. The hydraulic accumulator is an energy storage device in the hydraulic and pneumatic system. The energy in the system is converted into compression energy or potential energy and stored. When the system needs it, the compression energy or potential energy is converted into hydraulic or pneumatic energy and released to replenish the system. When the pressure of the system increases instantaneously, it can absorb this part of the energy to ensure the normal pressure of the whole system.

At present, the cooling of the accumulator body with slow pressure energy storage on the hydraulic control system is to cool the accumulator body by winding the cooling pipe outside the accumulator body, and using the cooling medium to flow in the cooling pipe on the accumulator body to cool the accumulator body. The cooling medium in the pipeline not only has a small contact surface with the accumulator body, but also does not directly contact the cooling and heat exchange between the cooling medium and the accumulator body, so that the cooling of the accumulator body is slow, and the cooling pipeline cannot affect the accumulator body. The outside of the main body plays the role of anti-collision protection, which is poor in practicability.
