Vacuum Pump : Constructional, Principle of Operation & Applications

Definition: It is defined as a device that removes gas molecules, or water molecules from a particular enclosed space and leaves a vacuum behind. The vacuum is defined as the absence of air. So the vacuum pump removes air for air conditioning systems, or water for refrigeration systems to create a vacuum behind.

Construction and Principle of operation for Valve Actuators

Hydraulic actuators provide for semi-automatic or automatic positioning of the valve, similar to the pneumatic actuators. These actuators use a piston to convert a signal pressure into valve stem motion. Hydraulic fluidis fed to either side of the piston while the other side is drained or bled.

Butterfly valve Principle of operation

The closing mechanism is a disk that rotates. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe.

The Bernoulli principle therefore explains the main reasons for fluid flow that physicists need to consider in fluid dynamics. Either the fluid flows as a result of elevation (so its potential energy changes) or it flows because of pressure differences in different parts of the fluid (so fluids in the high-energy, higher-pressure zone move to the low-pressure zone).

Recirculating-ball Steering - How Car Steering Works | HowStuffWorks

Instead of the bolt directly engaging the threads in the block, all of the threads are filled with ball bearings that recirculate through the gear as it turns. The balls actually serve two purposes: First, they reduce friction and wear in the gear; second, they reduce slop in the gear. Slop would be felt when you change the direction of the steering wheel -- without the balls in the steering ...
