10.3 ELECTRICAL SYSTEM
The machine is adapted to alternating current of 3 x 400 V / 50 Hz.
It is supplied with four-wire power supply cable;
the green-yellow wire is a protective
conductor while the other three wires are the phase conductors.
The main power switch is located on the control box – figure 1.
The machine is supplied with two control panels. The description of particular parts of
each panel is presented in the figure 2. The electrical system scheme is presented in
the figure 6.
10.4 HYDRAULIC SYSTEM
Straightening and mounting operations on the machine are carried out by means of
the hydraulic servo-motors. The use of the hydraulic pump provides the pressure of
200 bar – the working pressure at the overflow valve is set at 160 bar. The
monoblock
two-chamber hydraulic divider enables to change the direction of the
servo-motor pistons movement. The straightening piston’s control chamber is
switched by means of the hand lever, while the adapter piston’s chamber – by means
of the electromagnets (switched on by the control panel).
The capacity of the oil tank on the hydraulic pump is about 8 litres. The oil level is
checked on the oil indicator – figure 3.
The hydraulic system’s scheme is presented in the figure 7.
11.0 WHEEL RIM STRAIGHTENING MACHINE OPERATION
The machine is supplied with the hydraulic system to mount wheel rims. Clamping is
carried by the hydraulic servo-motor set in the central position by means of a suitable
adapter - figure 4.
There are three mechanical pressures supplied:
- a four-bolt mechanical pressure and a five-bolt mechanical pressure with regulated
setting of bolts from dimension 98 mm to dimension 140 mm.
- a universal mechanical pressure (three-, four-, and five-bolt with regulated setting of
bolts from dimension140 mm to dimension 210 mm (dimensions 98-210 mm for the
three-bolt system).
