How do pumps work?There are really just two different kinds of pumps: reciprocating pumps (which pump by moving alternately back-and-forth) and rotary pumps (which spin around).Reciprocating pumpsBicycle pumps are perhaps the most familiar examples of reciprocating pumps. They have a piston that...
An engine compresses fluids (air-fuel mixture), which ignites to push the piston downwards. The piston, in turn, moves the crankshaft. In two-stroke engines, pistons also serve as inlet and outlet valves. Thus, engines, unlike pumps and compressors, derive motion from the combustion of compr...
A flow meter at petrol station pumps measures the amount of fuel being dispensed from the pump. Fuel delivery trucks are also fitted with flow meters to measure the energy flowing through them. These devices are generally piston-type positive-displacement flowmeters. They are considered the gold ...
Breastfeeding is a healthy way to feed young children, but busy schedules and other factors may keep mom from being available when baby's hungry. Breast pumps can help bridge that gap.
The pumps used in sprayers and pumps at Container & Packaging Supply are called piston pumps, and are a type of reciprocating positive displacement pump. What those big words mean is that these pumps move liquid in one direction. How do these pumps make sure that the liquid only goes one ...
PD pumps come in a variety of mechanical designs, to name a few: Circumferential Piston Pumps Rotary Lobe Pumps Twin-Screw Pumps Progressive Cavity PumpsA Positive Displacement Pump Curve answers several important questions during the pump selection process: What flow rate is the pump capable of?
You can see hydraulics at work in this digger. When the driver pulls a handle, the digger's engine pumps fluid into the narrow pipes and cables (shown in blue), forcing the hydraulic rams (shown in red) to extend. The rams look a bit like bicycle pumps working in reverse. If you ...
The number of cylinders that an engine contains is an important factor in the overall performance of the engine. Each cylinder contains a piston that pumps inside of it and those pistons connect to and turn the crankshaft. The more pistons there are pumping, the more combustive events are tak...
There are two types of jet engine starters: axial piston pumps and rotary piston pumps. An axial piston pump is operated by one or two rotating pistons that are connected to each other inside an attached cylinder. A rotary piston pump has one or two rotating pistons, a fixed cylinder ...
