1.3 Technical Description
The pump is an electromechanical unit designed to supply compressed air to the
garments while controlling the inflation time and pressure.
In addition, an electronic module monitors pressure and fault conditions only. It
is independent of the control system , and functions independent of thepump
pressure.
Referring to the schematic diagram (Figure 1.1), the key parts of the pump are
as follows.
1.
Compressor
This provides a constant flow of air to the pneumatic system, thus allowing
inflation of the garments.
2.
Rotary Valve
This controls the delivery of pressure to the garments and sets the duration and
frequency of the garment inflation.
3.
Pressure Control Valve
This sets the maximum pressure that can be delivered to the garments.
4.
Differential Pressure Transducer
This measures the pressures at each garment part and provides the monitoring
system with the means of accurately measuring relative pressures in the two
garments.
5.
Electronic Monitor
The electronics in the monitoring system perform continuous checking of the
operation and performance of the pneumatic circuit. In the event of a detected
fault, the electronic monitoring system generates both audible and visual alarms.
6.
LED-Pressure and Message Display
The monitored pressure is displayed on the dual, seven segment display in real
time. In the event of a detected fault, the relevant fault message is displayed.
