1.4 Regulating system on SF Skid - Tank-mounted - Twin

The air net pressure is kept within limits by a pressure switch mounted in the cabinet below the control panel (Fig. 1.10). The switch is connected to the air outlet and electrically connected in the circuit of the drive motor. The switch opens and closes its contacts at pre-set pressures.

Fig. 1.10 Control panel SF Skid - Tank-mounted - Twin

When the contacts are closed, the circuit to the drive motor is made: the compressor is operating. The air output is maximum.

When the pressure reaches the pre-set maximum, the circuit to the drive motor is broken, causing the compressor to stop. The air output is stopped.

Protecting the compressor

The compressor will be shut down in case temperature switch (TSHH11-Fig. 2.7) trips.

Warning

Before carrying out any inspection or repair, stop the compressor, switch off the voltage, open the isolating switch and depressurize the compressor.
