    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY 3 INTRODUCTION 3.1 Piezoelectric Disc Pump Development Kit The Piezoelectric Disc Pump Development Kit expands the use of disc pumps across a variety of applications through advanced functionality that includes multi-pump control, valve control & sensor compatibility, enabling the creation of advanced prototypes and speeding up development times.
  • Page 7 THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY Figure 1 Principle of operation In contrast to conventional air pumping mechanisms (such as diaphragm and piston pumps), our disc pumps do not rely on the bulk compression of air within a cavity. Instead, our micropumps generate a high amplitude, high frequency acoustic standing wave within a specially designed acoustic cavity.

    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY 6.2.4 Filter TAKE NOTE! Ensure that a filter is connected to the pump inlet during operation. The filter included in the kit should be always used when the pump is running. This ensures debris does not enter the inlet of the pump as that can lead to degraded performance and shortened lifetime.

  • Page 16: Orifice

    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY 6.2.5 Orifice The orifice allows the pressure in the discharge line (or system) to decay more quickly when the pump is not running. This setup (as seen in Figure 16) will make tracking a pressure point with PID control more precise and quicker to converge.

    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY 6.3 Pump mounting guidance The Development Kit itself does not include a pump or Smart Pump Module. Pumps, modules and other accessories can be ordered as additional line items as required when ordering the Development Kit. Depending on the pump model, each pump has either two or three mounting eyelets.

  • Page 18: Electrical Connection

    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY 6.4 Electrical connection The disc pumps use an FFC (flat flex connector) compatible with most 8-way 0.5mm pitch FFC connectors. The Disc Pump Driver PCB has such a connector, and it is important that the disc pump “Flexi Tail” is properly seated in this connector, see Figure 19 below.

  • Page 40: Valve Troubleshooting

    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY 9.2.3 Valve troubleshooting Lee solenoid valves use an elastomer to create a leak-tight seal. Due to the elastomer’s inherent stiction, extended periods of valve inactivity may have an impact on the initial response time of the valve. Allowing liquid to dry out in the valve will also impact valve response time.

  • Page 55: Plotting

    THE LEE PIEZOELECTRIC DISC PUMP DEVELOPMENT KIT: MANUAL COMPANY Note that the choice of pressure / flow unit affects the PID values required for good control. The PID calculation is dimensionless, and so will treat a change of 1mBar (when measuring pressure in mBar) as equivalent to a change of 1PSI (when measuring pressure in PSI) because they are both changes of “one unit of pressure”.
