Ultra-High-Pressure Hydraulic Intensifier

Ultra-High-Pressure Hydraulic Intensifier

Developer: Laboratory of Stone Mining Complexes

Purpose and scope:

The ultra-high pressure hydraulic amplifier is designed to create high pressure working fluid in equipment for hydraulic and water abrasive processing of materials. It can be used in mining, mining and processing, construction, engineering, and other industries, where there are technological operations of hydrojet processing of materials.

Brief description and design features

Hydraulic amplifier ultra-high pressure liquid allows a 25-fold increase in the input pressure. When using a pressure amplifier in hydrojet processing plants of materials, the escape rate of a jet of water from a nozzle with a diameter of 0.1-0.3 mm reaches 1000 m / s, which allows cutting materials with a strength limit up to

⁇ v = 520 MPa. The working tool is water. When using a pressure amplifier in installations

Waterjet cutting (HAR) for cutting the material of the same strength will require a jet speed of waterjet mixture up to 680 m / s, i.e. at lower pressure and energy consumption.

A feature of the design is to ensure consistency of fluid movement along the highways by a system of reverse valves, where the same water is used as the control and working fluid.

Technological and economic advantages

Possibility of multiple increase in liquid pressure with small dimensions of the amplifier.

Level of development

Technical project. According to the results of the study and refinement of the experimental sample, the design of the hydraulic pressure amplifier was refined.

Patent protection

The principal scheme of the hydraulic pressure amplifier is protected by the patent KR No. 1177 KG C1 dated 29.08 2009.

Commercial offers

It is proposed to conclude contracts for the manufacture and supply of products, as well as for further research to obtain competitive products.
