By Jeremy Beale One hydraulic design approach that can be used to minimize valve size/losses is to incorporate opposite-phased cylinders into an application. It is most suitable under the following conditions: 1. Pressure and flow requirements match “high-low” operations. Here cylinder motion involves a low-pressure, high-flow stage; and a second a high-pressure, low-flow stage. A…
In the collection of hydraulic valve components, flow control valves are any device manufactured for the purpose of modifying the rate of fluid flow in a portion of a hydraulic circuit. Flow variability occurs through the adjustment of the effective orifice size inside the valve, and this is achieved through various techniques based upon the […]
The breast pump’s last significant redesign was in 1956, the year Elvis Presley released his first single. That changed in 2015 when, while on vacation, Samantha Rudolph read The New York Times blog article that asked, “Shouldn’t the breast pump be as elegant as an iPhone and as quiet as a Prius by now?” Although […]
Webtec has launched a new on-line hydraulic oil viscosity calculator app which calculates the viscosity of hydraulic oil at different pressures. Hydraulic fluid suppliers provide oils with different viscosities. These oils are most-often badged in terms of their ISO number or grade, where common grades for hydraulic circuits include ISO 32, 46 and 68. Using […]
Manuli Hydraulics announces the launch of its new HydroRope range of premium hydraulic hoses for grappling applications . When selecting a hydraulic hose for most normal applications, the tensile strength of the hose is not usually a critical determining factor. However, in certain specialist applications, such as the hydraulic grabs used in diaphragm wall building […]
