HYDRAULIC PUMPS Importance of Hydraulic Pumps For many everyday needs in both domestic life and industry, substances need to be propelled through pipelines,
. HYDRAULIC MACHINES. HYDRAULIC MACHINES… DEFINITION OF MACHINE A machine is an energy transformer. The machine absorbs energy of one kind and restores energy of another kind or of the same kind.
CONCEPTS OF HYDRAULICS AND PNEUMATICS Fundamental quantities of the International system. The fundamental magnitudes are grouped in systems of units. – Length, whose basic unit is the meter (m) – Length, whose basic unit is the meter (m).
Forced circulation boilers
Air cooling towers or TARs, also called cooling towers, are used to cool a liquid, usually water, using a gas, usually ambient air. This is a special case of a heat exchanger where heat transfer takes place by direct or indirect contact between the flows. Cooling towers are common equipment, present in air conditioning installations, or in industrial and energy processes (power plants, combustion plants, sugar mills, chemical plants, etc.).
Assisted Circulation Boiler
When the burner starts up or when the flame goes out during the operation of the equipment, the safety devices must comply with the safety times of the industrial boiler.
The control box in industrial boilers is going to control that during continuous service in operation, the safety shutdown devices work properly in order to be able to cut off the fuel supply to the corresponding burners, if any of the following circumstances occur:
The most widespread system to sustain the combustion process, is the installation of fans in industrial boilers to provide a forced draft complementing any kind of natural draft available.
Liquid fuels for industrial boilers, such as heavy fuel oils, need some initial preheating to reach the viscosity required for proper atomization.
A drop in the level indicator may be due to the fact that the water feeding the boiler does not arrive with the corresponding flow rate due to: valve failures, excess deposits in the connections, failures in the feed pump, etc…

Although many theoretical studies have been carried out to determine the possibilities and limitations of the well-known systems that have been used in the pneumatic transport of solids, in spite of this, at the time of making the different particular applications, the “know house” of each specialist firm continues to be used, which is based on simple methods and proven values in satisfactory daily practices. Therefore, it can be said that the engineering of this branch of technology is not scientific but constitutes, like many others, an Art.
Examples of variation can mean, for the same material with different grain shape, air requirements in the order of 60% higher and for cases of very similar physical properties and also the same pressure, the same amount of air and the same piping system, it can mean twice the conveying capacity. All this makes us understand the difficulty of theorizing on pneumatic conveying technology and the need to resort to the practice of real cases of installations, contrasting it with the first investigations carried out in the laboratory and in semi-industrial plants.
