How to specify gas struts accurately | Engineer Live
WEBMar 28, 2019 · Gas Spring Force (F1) = Mass of lid x Centre of Gravity / Radius of Force x Number of Springs. Closing Force Calculation. Similarly, the force required to close the lid (F2) can be calculated using the formula: Closing Force F2 = Number of Springs x Spring Force F1 x Radius of Force / Lid Length. Calculation of the opening and closing forces ...
How To Choose The Right Process Control Valves - Engineer Live
WEBMay 12, 2020 · Control valves are used to manage the flow rate of a liquid or a gas and in turn control the temperature, pressure or liquid level within a process. As such, control valves are defined by the way in which they operate to control flow and include globe valves, angle seat, diaphragm, quarter-turn, knife and needle valves, to name a few.

Radial and thrust forces in bearings - Engineer Live
WEBOct 4, 2018 · Here, Chris Johnson, managing director of SMB Bearings, explains. A radial load acts perpendicular, at 90 degrees, to the axis of rotation, while a thrust load — also known as an axial load — acts in parallel to the axis of rotation. Any misalignment of the shaft can also result in a moment load, a tilting force that can increase wear.
Positive displacement meters: pros, cons and selection
WEBFeb 21, 2013 · All PD meters require clean fluid so a filtration level of 100µm is usual. Some meters can actually block the flow if a larger particle is trapped in the wrong place. Many meters are not made in high specification materials and therefore corrosion can be a concern. An all plastic or all 316SS meter is the exception rather than the rule.
