Title:
MULTI-STAGE MULTIPURPOSE HYDRAULIC PRESSURIZER WITH VARIABLE PRESSURIZATION RATE
Document Type and Number:
WIPO Patent Application WO/2019/205471
Kind Code:
A1
Abstract:
Provided is a multi-stage multipurpose hydraulic pressurizer with a variable pressurization rate, comprising a multi-stage pressurizing structure part, a hydraulic oil loop, a control part of the hydraulic oil loop, a pressurizing fluid loop and a control part of the pressurizing fluid loop. A multi-stage pressurizing structure comprises a hydraulic cavity (C1), a first-stage pressurizing cavity (C2), a second-stage pressurizing cavity (C3) and a third-stage pressurizing cavity (C4). The hydraulic oil loop and the control part thereof comprise an electromagnetic stroke limiting switch, a three-position four-way electromagnetic reversing valve (10), a controller (11), a hydraulic oil inlet (P3) and a hydraulic oil return port (P4). The pressurizing fluid loop and the control part thereof comprise a one-way valve, a hydraulic control one-way valve, a two-position two-way electromagnetic reversing valve, a pressurizing fluid inlet (P1), a non-pressurizing-fluid outlet (P2) and a pressurizing fluid outlet (P5). According to the multi-stage multipurpose hydraulic pressurizer with a variable pressurization rate, high-pressure fluids, not only limited to water or hydraulic oil, with different pressurizing rates can be output while the pressurizer is not replaced under the action of the multi-stage controller, the using range and pressurizing environment of the pressurizer are enlarged, and the one-pressurizer multi-pressure and one-pressurizer multipurpose effects can be achieved.
