Intelligent Switching Method of Combined Accumulator

Abstract

The invention discloses an intelligent switching method of a combined type energy accumulator and belongs to the technical field of energy accumulators. The intelligent switching method comprises thefollowing steps: A, initializing a single-chip microcomputer: controlling a controllable electromagnetic valve to communicate hydraulic oil into a main energy accumulating chamber; B, acquiring data:during the using process of a diaphragm in the main energy accumulating chamber, adopting a pressure sensor to store acquired pressure variation data obtained when hydraulic oil enters and goes out ofthe main energy accumulating chamber in an intermediate storage; and C, switching the energy accumulating chamber: when the single-chip microcomputer determines that the acquired accumulative deflection times and the adjusting response time of the diaphragm simultaneously reach the dangerous limiting values of empirical data, controlling the controllable electromagnetic valve to act to cut off the oil way entering and going out of the main energy accumulating chamber, and communicating hydraulic oil into a standby energy accumulating chamber at the same time. According to the intelligent switching method, through detecting and judging the state of the diaphragm which is being used in the energy accumulating chamber, the controllable electromagnetic valve is adopted to timely switch to another standby energy accumulating chamber so as to realize intelligent switching, and normal operation of the adopted equipment is ensured.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to an intelligent switching method for combined accumulators. Background technique [0002] The accumulator is widely used in various hydraulic systems. It is an auxiliary device for storing energy, reducing noise and adjusting the random pressure fluctuation constant inside the hydraulic system. It can randomly convert the energy in the hydraulic system into compression energy or potential energy and store it. When the system needs it, it can convert the compression energy or potential energy into hydraulic or pneumatic energy and release it to replenish the supply system: when the system pressure increases instantaneously When the pressure is large, it can absorb or release part of the energy; thereby ensuring that the pressure of the entire system is adjusted within the normal pressure range and normal time interval. [0003] There are many kinds of accumulator ...

AI Technical Summary

Problems solved by technology

[0004] There are at least the following technical problems in the prior art: when the diaphragm in the accumulator is used for a certain period of time, it may be fatigued, aged, damaged, and eventually cause the accumulator to fail

The hydraulic system of the equipment in the working state fails. At this time, it is necessary to stop the use of the equipment and disassemble the accumulator for replacement, which will affect the work efficiency and seriously cause the failure of online equipment or cause major accidents.
