Q-Drive Actuator
To increase gas pressure, the electrically-driven Actuator moves the Drive Rods in the Gas Sections.
Coolant
Circulating coolant draws heat from the gas sections and the lubrication circuit. A Chiller must be
connected to the coolant ports.The capacity needed for the Chiller depends on your application.
Consult with Haskel representative for specific recommendation for your application.
Modes of Operation
Three modes of operation control the way the system functions.
Compressor Mode
The most common mode is to run the system continously, depleting the inlet gas vessel and filling the
outlet gas vessel. The pump runs until the gas pressure reaches the value of the Target Output
Pressure and then stops until the gas pressure decreases to the deadband value that is set by user.
The deadband is the range of pressure values in which no operations occur. At the deadband value,
the pump restarts and increases the gas pressure to restore it to the target pressure.
Fill & Pause Mode
The pump runs until the gas pressure reaches the value of the Target Output Pressure and then
pauses. The system is still running and gas is still in the system, but the pump is paused. To restart
the pump, tap the Ack button
Fill & Stop Mode
The pump runs until the gas pressure reaches the value of the Target Output Pressure and then
stops. The air-actuated valves block the inlet and outlet pressure and vent the Q-Drive system.The
compresson is now concluded.
User Interface
A Programmable Logic Controller (PLC) monitors temperature and pressure of the non explosive
process media throughout the system. The Human-Machine Interface (HMI) connects to the PLC to
display the values on the touchscreen and allows you to make changes. You can view the status and
current values at any time, but you must log in to the HMI to make changes.
The HMI screen is a touchscreen where user can see a button or icon, tap the screen to simulate
pressing it.
Buttons or icons that have the appearance of height indicate a value user can
change.
Areas of the screen that have a recessed appearance indicate a current value of
live data that user cannot change.
User Accounts
The HMI has 3 standard accounts:
The Supervisor account can make any changes to the operation of the system.
The Operator account can stop and start operations, but cannot change parameters:
The Service account can reset the counters after preventive maintenance.
