Switches for low-pressure applications feature diaphragm pressure switches<ins cite="mailto:Config" datetime="2015-02-05T15:16">,</ins> while high-pressure switches have a compact piston design. An increase in pressure above the set-point activates the single-pole, double-throw (SPDT) micro switch and resets as the pressure returns below the set-point. The set-point can be adjusted with a screw on the switch.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/hydraulics/compact-modular-switches-target-highlow-pressure-hydraulics" target="_blank">read more</a></p> http://machinedesign.com/hydraulics/compact-modular-switches-target-highlow-pressure-hydraulics#comments Hydraulics Mon, 09 Feb 2015 15:41:00 +0000 46061 at http://machinedesign.com A Hydraulic Pump for High-Pressure Applications http://machinedesign.com/whats-inside/hydraulic-pump-high-pressure-applications <div class="node-body article-body">Engineers at Moog developed the RKP 250 radial piston pump, in part, to let customers pump more volume using a smaller motor with a simplified interface. </div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/whats-inside/hydraulic-pump-high-pressure-applications" target="_blank">read more</a></p> http://machinedesign.com/whats-inside/hydraulic-pump-high-pressure-applications#comments What's Inside?
