Centrifugal Compressors Study Unit

Product Code: LBNY-0005-13700015 - (Centrifugal Compressors Study Unit)

The compressor is driven by a variable speed d.c. electric motor with a belt gearing-up system of O to 4000 RPM with a transmission ratio of 7.5/1.If is possible to read the pressure values, upstream and downstream of the compressor, by means of 2 U shaped differential manometers. The industrial type compressor used in this apparatus is a single stage machine having a 127 mm dia impeller and an aluminium scroll with fluid threads rectifier. Thermometers are inserted into the circuit in order to read the air temperature before and after the passage through the centrifugal compressor. At the maximum speed of over 29,000 RPM, if develops a downstream pressure of about 230 mmHg with a max air capacity of 1230 kg/h.

Centrifugal Governor

Product Code: LBNY-0005-1300003 - (Centrifugal Governor)

Centrifugal Governors use the properties of centrifugal force to control the speed of a machine. These mechanisms are differentiated into those governors that use weights and those that use springs. Due to centrifugal force, a rotating flyweight mass has the tendency to move away from the axis of rotation and is prevented by counteracting mechanisms.

Features:
Determination of characteristic curves and setting curves of different centrifugal governors
Visualisation of the effect of centrifugal force
How various centrifugal systems work
