AI Technical Summary

Technical Problem

Existing accumulator charging methods are complex and prone to misoperation, and are not suitable for energy storage landing equipment with a rotating boom structure, resulting in safety risks during emergencies.

Method used

An accumulator charging system was designed, including an accumulator, an oil tank, a hydraulic pump, a filter, a proportional multi-way valve, and a charging valve. The hydraulic pump is driven by an electric motor to provide oil pressure, and the charging process is automatically controlled by a pressure relay, avoiding reliance on hydraulic actuators, especially hydraulic cylinders.

Benefits of technology

It achieves automated control of accumulator charging, reduces operational complexity and the risk of misoperation, and is applicable to energy storage landing devices of various structures, especially rotating structures, thus improving safety and applicability.

Abstract

The utility model provides a kind of accumulator pressure charging system, including accumulator, oil tank, hydraulic pump, filter, proportional multiway valve and pressure charging valve, oil tank is communicated with proportional multiway valve by pipeline, forms first loop, there is hydraulic pump in first loop communication, for providing oil pressure, pressure charging valve is communicated with the low pressure circulation valve of proportional multiway valve by pipeline, forms second loop, one side of accumulator is communicated with hydraulic pump, forms third loop, pressure relay is also installed on accumulator, pressure relay is electrically connected with pressure charging valve, for controlling the on-off of second loop and third loop;When pressure charging system is closed, first loop is communicated, second loop and third loop are not communicated, when pressure charging system is stamping, first loop is not communicated, second loop and third loop are communicated, so that accumulator pressure charging method is convenient, simple, and not dependent on any hydraulic system execution element, misoperation condition is not easy to appear.
