A Multistage Multipurpose Hydraulic Booster With Variable Boosting Ratio

Abstract

The invention discloses a multi-stage multi-purpose hydraulic booster with variable boosting ratio, which comprises a multi-stage boosting structural part, a hydraulic oil circuit and its control components, a boosting fluid circuit and its control components; the multi-stage booster The structure includes a hydraulic chamber, a first-stage pressurized chamber, a second-stage pressurized chamber and a third-stage pressurized chamber; the hydraulic oil circuit and its control components include electromagnetic travel limit switches, three-position four-way electromagnetic reversing valves, controllers, hydraulic pressure Oil inlet and drive hydraulic oil return port; pressurized fluid circuit and its control components include check valve, hydraulic control check valve, two-position two-way electromagnetic reversing valve, pressurized fluid inlet, non-pressurized fluid outlet and pressurized fluid outlet. The boost ratio variable multi-stage multi-purpose hydraulic booster can output high-pressure fluids with different boost ratios not limited to water or hydraulic oil without changing the booster under the action of the controller through multi-stage control. The scope of use of the supercharger and the supercharging environment are expanded, and the effect of one device with multiple pressures and one device with multiple functions can be achieved.

Description

technical field [0001] The invention relates to a supercharger, in particular to a multi-stage multipurpose hydraulic supercharger with a variable boost ratio, and belongs to the technical field of hydraulic control devices. Background technique [0002] The hydraulic drive system in industrial equipment is generally divided into two types: low-pressure system and high-pressure system. If there are individual components in the equipment driven by the low-pressure system that need to be driven by the high-pressure system, an oil circuit needs to be branched in the low-pressure system, and installed on this oil circuit. Hydraulic booster, so that the low-pressure oil in the low-pressure system can be converted into high-pressure oil or even ultra-high-pressure oil required by the high-pressure system, which is convenient and practical. [0003] The traditional hydraulic booster includes control tools such as base, low-pressure cylinder, connecting valve, high-pressure cylinder...

AI Technical Summary

Problems solved by technology

However, the traditional supercharger, such as the supercharger on the machine tool, can only be boosted once, and then needs to be re-pressurized on the return trip, and cannot be continuously boosted.

And when it is necessary to use different multiples of boost pressure, the supercharger must be disassembled and replaced to achieve the desired effect. The disassembly process is cumbersome, time-consuming and laborious, and lacks economy and practicability

In addition, most of the traditional superchargers only have one oil inlet, one oil return port and one high-pressure oil output port, and the supercharger is only suitable for hydraulic oil, and it cannot be boosted for different fluids, which limits the scope of use
