Description
3.1
Base Unit
3.1.1 The base unit is of rigidly constructed welded steel that houses both the motor drive
unit (1) and speed controller (2).
3.1.2 The speed controller incorporates a switch to provide an electro-mechanical brake to
minimize the time required to stop the centrifuge. This is operated when the controller
is turned fully anti-clockwise past zero.
3.1.3 The motor is attached to the main bearing assembly (3) and drive shaft (4) that
retains and drives the centrifuge bowl.
3.1.4 The top end of the drive shaft engages with a stabilizing bearing fitted to the top cover
of the centrifuge.
3.1.5 The drive shaft incorporates a spigot (5) that engages with the bowl.
3.2
Light alloy bowl assembly
3.2.1 The bowl assembly comprises an inner centrifuge unit and a protective bowl and
cover.
3.2.2 The inner bowl (6) slides on the shaft (4) to engage with the driving spigot (5).
3.2.3 A cover (7) is provided for the centrifuge bowl and is clamped to it by means of the
knurled nut (8).
3.2.4 The whole assembly is easily lifted from the apparatus for purposes of weighing and
the use of more than one centrifuge bowl.
3.2.5 The outer bowl (9) is rigidly fixed by 4 bolts (15) to the base unit and the bearing
assembly (3).
