Classification of Hydraulic Pumps Hydraulic pumps can be classified into two main categories: Positive displacement pumps Non-positive displacement pumps The majority of pumps utilized in hydraulic systems are positive displacement types, which are prevalent in automation applications. Non-positive displacement...
Fuel cells are usually classified by their operating temperature and the type of electrolyte they use. Some types of fuel cells work well for use in stationary power generation plants. Others may be useful for small portable applications or for powering cars. The main types of fuel cells ...
The first fire engines were water pumps pulled to fires by horses. These days, when you hear the word “engine,” you probably think of machines like steam engines and internal combustion engines, which use fuel to produce torque or linear force to do mechanical work. Engines are devices ...

The former are most commonly used on stationary and marine boilers. As their mechanism is much the same as that of ordinary force pumps, which will be described in a later chapter, we may pass at once to the injector, now almost universally used on locomotive, and sometimes on stationary ...
The four cylinders are those four tubes the pistons are moving up and down inside of. Each time a piston slides up or down, that’s called a stroke, and the fuel-burning happens in a four-stroke cycle: 1) The Intake Stroke: This is the part where the piston is moving down and ...
Also, they are manufactured in die-cast aluminium and feature an integral re-circulating valve to regulate pump pressure, Concentric said. Concentric to supply oil and coolant pumps for JCB's 6-cylinder engine The variable flow of the constant pump and power is presented in addition to the pum...
There are several differenttypes of fuel cells, each using a different chemistry. Fuel cells are usually classified by their operating temperature and the type of electrolyte they use. Some types of fuel cells work well for use in stationary power generation plants. Others may be useful for smal...
