Blade-type hydraulic transformer controlled by hydraulic cylinder

Abstract

A blade-type hydraulic transformer controlled by a hydraulic cylinder comprises a double-acting variable unit, a single-acting variable unit, a shell, a right end cover, a rotating shaft, a left end cover and the like. The transformer is characterized in that the double-acting variable unit and the single-acting variable unit share one rotating shaft; the left end of the rotating shaft is installed on a thrust plate at the left side of the double-acting variable unit via a sliding bearing and the right end thereof is installed on the right end cover via a sliding bearing; a rotor of the double-acting variable unit is fit-connected with a left half shaft of the rotating shaft by a spline; a rotor of the single-acting variable unit is fit-connected with a right half shaft of the rotating shaft by a parallel key; the double-acting variable unit and the single-acting variable unit are installed in the same shell; the right and left end covers are fixed on the shell by bolts. The transformer has the benefit of adjusting the pressure of the constant pressure rail system to any value within the variation range of the load pressure by the way of no throttle loss so as to expand the application range of the hydraulic transformer and enrich the variety of the hydraulic transformer.

Description

(1) Technical field [0001] The invention relates to a hydraulic transformer, in particular to a blade-type hydraulic transformer controlled by a hydraulic cylinder, which belongs to the field of machinery. (2) Background technology [0002] A hydraulic transformer is a hydraulic component that realizes pressure conversion in hydraulic transmission. The hydraulic transformer can efficiently convert the input hydraulic energy under a given pressure into the output hydraulic energy under another pressure. Using it can realize the independent control of multiple loads in the constant pressure network, and also make the energy reverse flow , not only can drive linear loads without throttling loss, but also can drive rotary loads.

Problems solved by technology

[0003] The existing hydraulic transformers are basically plunger-type structures, with high working pressure above 20Mpa and large flow range. They are generally used in high-pressure and large-flow hydraulic systems, and in medium and low-pressure hydraulic systems, the efficiency is very low. , and the plunger hydraulic transformer has a complex structure, high processing precision, is sensitive to oil pollution, requires high oil filtration precision, and is expensive, so the application range of hydraulic transformers is greatly limited.
