  • Page 11: Safety

    Refer to the safety section of your particular dispensing system Operations Manual prior to installing and operating your DispenseJet Series DJ-9500. Safety is considered a joint responsibility between the original equipment manufacturer (Asymtek) and the end-user (owner).

  • Page 12: Preventing Equipment And Workpiece Damage

    CAUTION! The DispenseJet Series DJ-9500 is a precision instrument of inherently safe design. The use of any dispensing fluid and the related choice of solvent for cleaning, as well as all associated safety precautions is the responsibility of the end-user.

  • Page 13: Theory Of Operation

    Theory of Operation Overview The DJ-9500 is a normally closed, air-actuated, spring-return mechanism, which uses momentum transfer principles to expel precise volumes of material. Pressurized air is regulated by a high-speed solenoid to retract the Needle Assembly from the seat. Fluid, fed into the fluid chamber, flows over the seat. When the air is exhausted, the needle travels rapidly to the closed position, displacing fluid through the seat and nozzle in the form of a droplet.

  • Page 14: Body Heater

    Body Heater The Body Heater helps hold the DJ-9500 series assembly at constant temperature to protect it against transient temperature fluctuation in the machine. The Heat Exchanger version will supply a fluid at a constant temperature. Stroke Adjustment Knob Assembly Reservoir Holder Needle Assembly Fluid Reservoir...
