Optimization of Manufacturing Processes by Reducing the Costs of Tools and Equipment on Hydraulically Operated High-Pressure Technological Lines

Most technological manufacturing lines include hydraulically operated stationary tools, devices and equipment. During a cycle, there are phases, usually short, in which part of the hydraulic cylinders drive systems concerned, with small gauges displacement speeds, have to generate / maintain high clamping or pressing forces, implies functioning at working pressures. The solution for such is use modular pumping units comprising: oil tank; low-pressure electric pump; directional valve starting, stopping changing direction cylinder; pump pressure control valve; filter; return oscillating intensifier (minibooster mounted directly on cylinder). Such units, consume low (in primary side minibooster) secondary minibooster), cost-effective when it comes procurement components, installing them, space required installation, their maintenance, too. classic applications using them achieving maintaining values, either volumes closed spaces (endurance tests pipes tanks), active stroke end (hydraulic presses). authors demonstrate, laboratory test bench, following: - range can be extended third direction, namely actuation gauge speeds constant load (high pressure) over entire stroke; uniformity these stroke, fed actuated by weakly affected pulsating mode operation intensifier.
