Method suitable for stable operation of leather bag type energy accumulator

Abstract

The invention relates to a method suitable for stable operation of a leather bag type energy accumulator. The method comprises the following steps that (1) according to the design requirements of a system, the lowest working pressure and the highest working pressure of the system and the capacity of the energy accumulator are determined; (2) according to the actual situation of a site and verification comparison, the capacity (whether the capacity needs to be increased) of the energy accumulator is mainly determined; (3) according to the system flow and the detected actual working pressure, the basic inflation pressure of the leather bag type energy accumulator is determined; (4) according to different use conditions of the leather bag type energy accumulator, the final inflation pressureof the leather bag type energy accumulator is determined; (5) by detecting the actual inflation pressure of the energy accumulator, the nitrogen pressure needing to be supplemented is determined; (6)nitrogen filling operation is carried out on the energy accumulator; and (7) the system stably operates and waits for the next detection.

Description

technical field [0001] The invention relates to an accumulator, in particular to a method suitable for the stable operation of a bladder type accumulator, and belongs to the technical field of hydraulic structural components. Background technique [0002] The accumulator is a device that stores the potential energy of the working medium. In the gap load of high pressure and large flow or the continuous load system of different sizes, sometimes the flow required by each stage in a working cycle is also very different, and the peak flow load The time is often relatively short. For this situation, although there are many solutions, an important way is to use accumulators as auxiliary energy, especially in the hydraulic system of constant pressure variable pumps. Due to the bladder type accumulator Energy devices have the advantages of small size, light weight, small inertia, sensitive response and strong shock absorbing ability, etc., and are widely used. When the flow require...
