Problems solved by technology

[0004] However, there is a problem with the existing accumulator. After the airbag is charged, the working pressure of the accumulator has been determined and cannot be changed. In some application scenarios, the working pressure of the hydraulic system will vary according to the working state. If there is a change, the accumulator needs to be replaced to adapt to different hydraulic system working pressures, and the online adjustment of the working pressure of the accumulator cannot be realized, that is, the working pressure of the accumulator cannot be adjusted when the accumulator is working

Abstract

The invention discloses an energy accumulator system and a water pump system. The energy accumulator system comprises a working energy accumulator (1), a pressure-adjusting energy accumulator (2) and a hydraulic adjustment device, wherein a working port of the working energy accumulator (1) is connected with a working system with pulse flow; the pressure-adjusting energy accumulator (2) is communicated with an inflation port of the working energy accumulator (1) and used for adjusting the pre-inflation pressure of the working energy accumulator (1); and the hydraulic adjustment device is communicated with a liquid filling cavity of the pressure-adjusting energy accumulator (2) and used for adjusting the pressure of the pressure-adjusting energy accumulator (2) so as to adjust the pre-inflation pressure of the working energy accumulator (1) to be matched with the working pressure of the working system. Through the invention, online adjustment of the working pressure of the energy accumulator can be realized.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an accumulator system and a water pump system. Background technique [0002] An accumulator is an energy storage device in a hydraulic system (or hydraulic system, pneumatic system), which is generally used to alleviate the sudden pressure change caused by the pulsating flow in the hydraulic system. The accumulator is generally equipped with an air bag. Before the accumulator is used, a certain amount of gas is filled into the air bag. The pressure of the gas at this time is called the pre-charge pressure or working pressure. [0003] When the accumulator is connected to the matching hydraulic system (the pre-charging pressure is slightly less than the normal working pressure of the hydraulic system), when the hydraulic system works normally, a certain amount of liquid will be pressed into the accumulator to compress the air bag until The pressure of the gas is balanced with t...
