The DC motors are used in a wide variety of industrial drives, such as robots, machine tools, oil drilling rigs, mining, automotive systems, etc. On the other hand, DC generators are still in use in some power generatingplants. The real difference between DC motor and DC generator is the directionof power flow. All the DC machines have a reversible behavior: they aremotors up to a frequency that is characteristic of the construction parametersand is said synchronism frequency, beyond which they behave as generators. The electric machines bench has been designed to satisfy thefollowing basic requirements:
The plan activities
The economic advantage
The number of groups of students who must worksimultaneously
Their speed can beeasily adjusted in very fine increments ranging from standstill to rated speedand even above and their construction is made rather complex than their AC counterparts by the fact that they need a commutator, which reverses thedirection of current and fluxes to produce a net torque. The DC machines are driven from a DC power supply and theyare the most versatile of all rotating electrical machines.

Flocculation chemicals can be added to the rawwater in order to improve the flotation of the contaminants. The diatomiteprovided is suitable as a contaminant. Flotationprocesses are used to separate solids from a liquid. The flotation process mostcommonly used in water treatment is dissolved air flotation. The suspension tobe treated is placed in a tank. A pump transports the raw water, whichenters the flotation column via a vertical pipe. The air dissolves in the water under pressure. Part of the waterflows back to the pump via a bypass. The other part of the water enters apressure vessel filled with Pall rings. The height of the supply linecan be adjusted. The pressure vessel ensures asufficiently long dwell time to dissolve the air and to separate undissolvedair. A water circuit with pump is connected to the flotationcolumn. Two compressors supply air to the water circuit on the suction side ofthe pump.
The water then enters the flotation column from below via a valve. This causesa sudden drop in pressure to almost atmospheric pressure. The contaminants rise up in thecolumn together with the air bubbles. At the upper end of the flotation column,the contaminants enter a circulating channel. Since the solubilityof air increases with increasing pressure, the excess air forms small bubbles.The air bubbles accumulate on the contaminants.

The Convective heat transfer In Air Flowand its accessories allow studying the convective heat transfer with different geometries of the transfer surface. Typical models such as the tubebundle, the heated tube from the outside and the heated cylinder from the inside are observed. Convective heat transfer is the transfer of heat between a surface and a fluid. Theprocesses of convective heat transfer are associated with the movements of the fluidthat is to say with convection. In the case of forced convection, thefluid is fed by a pump or fan onto the transfer surfaces, whereas in the caseof free convection, the flow occurs only under the effect of the density differential of the heated fluid. The air passes in front of the model, warms itself up and leaves by a ventilation shaft. In the air duct, aflow-friendly inlet member provides a homogeneous flow for conducting thetests. The volumetric flow rate is adjusted by a butterfly valve locatedat the fan outlet. An immersion heater, which can be placed anywhere in the tubebundle, simulates a heated tube. The convective heat transfer can thus be determined according to the position of the tube. Other models areavailable as accessories. It is also possible to show the chimney effect insidea ventilation shaft during free convection. The measuring section is an airduct with fan, in which the model of heat exchanger can be fixed easily and quickly using quick couplers. To make it possible to observe the tests, the air ductis equipped with two windows. The model included in the bundle heat exchanger delivery list includes two exchangeable tubular bundles of different geometries. The heating power and the volumetric flow can beadjusted. The heating power and the temperatures of the air and the heaterare displayed numerically. A pitot tube and a pressure measuring device make it possible to determine the speed distribution in front of and behind themodels.
