DESCRIPTION
The TS5000DMP Series Rotary Microvalve takes a revolutionary unique approach
to solving some of the most difficult dispensing problems. Two-component fluids
present a significant dispensing challenge, and the possibility of destroying
precision valve components, upon premature curing. Highly abrasive fluids
eventually decrease accuracy that is followed by total valve failure. With the
patented Disposable Material Path (DMP) Rotary Microvalve from Techcon
Systems, those concerns are erased.
A precision molded feed screw and chamber is captured in a “clamshell” design
valve housing. Inexpensive disposable feed screw and chamber components may
be changed quickly and easily. Cleanup is reduced to simply changing out the
disposable material path. An inexpensive stock of disposable valve components
replaces an inventory of back up valves.
The accuracy of the TS5000DMP valve meets the needs of users previously
constrained to lower accuracy of time/pressure dispensing. It also meets the
maintenance cost targets of users previously relegated to recurring, maintenance of
non-disposable path valves. Current TS5000 Rotary Microvalve customers may
find the accuracy of the TS5000DMP valve meet their current accuracy
specifications.

12. TROUBLE SHOOTING
PROBLEM
POSSIBLE CAUSE
Dispense tip is plugged
Motor does not receive signal
No Fluid Flow
Motor running in reverse
Syringe barrel of dispense fluid
is empty
Fluid feed pressure is too low
Feed screw damaged
CORRECTION
Replace tip
Make sure all connections are
secured
Reverse motor cable
connection
Replace with new syringe
barrel, of fluid
Increase feed pressure.
Replace with new feed
screw/chamber
Make sure fluid pressure is
constant

THEORY OF OPERATION
(refer to figure 1.0)
The TS5000DMP Series Rotary Microvalve dispenses fluid with a positive
displacement action using a rotary feed screw principle. Fluid is held in a feed
reservoir (2), normally a syringe barrel or cartridge, under a positive head of air,
between 1 to 20 psi (0.07 to 1.38bar), depending upon the viscosity of the fluid.
The positive air pressure, supplied by the air line (1), forces the fluid out of the
syringe barrel (2) into the material feed path (3) then to the feed screw chamber
(5). Fluid flows from this point (5) to the dispense point (4) and is controlled by
the feed screw rotation in the feed direction. The feed screw is driven by the DC
motor (6). Applying a DC voltage signal to the DC motor (6), will rotate the feed
screw and the fluid will be forced out the dispense tip (4). The actual fluid
deposited is dependent upon adhesion of the dispensed fluid to the substrate.
Shearing of the fluid is achieved by reverse Z-motion (tip retraction). When the
motor stops, the unit remains in position for a fraction of a second (dwell) to allow
the last drop of fluid to flow out of the dispense tip. After the dwell period, the
automation equipment moves the TS5000DMP valve to the next position.
