air bearing
Air bearing
An air bearing (also known as an aerostatic bearing or a pneumatic bearing) is a bearing in which a forces between two surfaces are supported by air pressure. In other words, it is a surface effect bearing. The air bearing provides a smooth, low friction and consistent movement on the......
The second law of thermodynamics second law of thermodynamics
The Second Law of Thermodynamics The Second Law of Thermodynamics states that the total entropy of an isolated system always increases over time. Entropy is a measure of the amount of energy available to do work in a system. Increasing entropy represents a loss of usable energy in the system. The S......
Hydraulic control valve---sequence valve
Hydraulic sequence valves
A hydraulic sequence valve is basically a pressure control valve. These valves act as a sequence device in a hydraulic circuit by controlling the order in which certain actions are taken. Sequence valves are used in many different types of machines, including industrial ......
Working principle of pulse plug flow pneumatic conveying pump
Pulse damped flow conduit pumping (PDFP) pumps are designed to provide a steady and consistent flow rate over a wide range of head pressures. The pump is based on a sealed and pressurized fluid conduit in which impulses of fluid are created and damped out at different pressure points. The conduit ......
