Embodiment Construction

[0022] Figure 4 It is a schematic diagram of the working connection of the hydraulic transformer. The rectangle in the figure represents the hydraulic transformer. Its internal structure and working principle have been analyzed before, and now only its external connection is further identified. The hydraulic interface 4 and the hydraulic interface 8 form the input primary circuit. The interface 12 and the hydraulic interface 15 constitute the output secondary circuit, and the two circuits are isolated from each other, so that the oil will not be mixed. Connect hydraulic port 4 to a constant pressure source such as an energy storage tank, and hydraulic port 8 to return to the oil tank, while hydraulic port 12 and hydraulic port 15 are both closed by valves. At this time, there is no input or output, and the inside of the transformer does not rotate. Measuring the pressure of the primary circuit will be the constant pressure of the accumulator tank and the secondary circuit wil...

Abstract

The invention relates to a hydraulic transformer, and belongs to the technical field of hydraulic elements. The hydraulic transformer is a hydraulic element which is quite wide in application range and quite important and indispensible for designing and constructing various hydraulic systems. When being applied to the hydraulic systems, the hydraulic transformer can be in analogy with a transformer in an alternating current system, constant pressure networks of the hydraulic systems are built, uncorrelated control over multiple loads is achieved. The hydraulic transformer comprises a rotor formed by a plurality of double-action hydraulic cylinders, the double-action hydraulic cylinders carry out pressure conversion according to the effects of pressurizing hydraulic cylinders under the effect of static pressure, and working principles and basic theories of the double-action hydraulic cylinders are the Pascal law for static pressure transmission. A primary loop is used as a hydraulic motor to drive the rotor to rotate, and a secondary loop serves as a hydraulic pump to continuously and stably output high-pressure oil.

Description

Technical field: [0001] The invention relates to a hydraulic transformer, which belongs to the technical field of hydraulic components. It is a widely used hydraulic component that is extremely important and indispensable for the design and construction of various hydraulic systems. Its application in hydraulic systems can be compared to The transformer in the AC system establishes the constant voltage network of the hydraulic system to realize the independent control of multiple loads. Background technique: [0002] In the prior art, there is a commonly used hydraulic component—a booster hydraulic cylinder. The booster hydraulic cylinder uses the difference in the cross-section of the piston or plunger in the two cylinders connected in series on the same axis to achieve the effect of boosting or lowering the pressure. The booster hydraulic cylinder It cannot be called a transformer because it can only transform voltage in a single pass, but cannot provide continuous and sta...
