6 PUMP & VALVE SYSTEM MODULE
6.1 Summary
Pump & Valve system module’s main function is to take certain amount of sample out of
the tube, transfer it into the microscopy field, after sample detection finished then washes
the pipeline system, in order to prevent cross-contamination. The main process could
divide into followed modules, such as Wash, Rev-wash, Maintain, Spe-wash, Sample, etc.
All the process modules are controlled by system processing center, if needed; orders
from system will assign a module to work automatically.
Fig.6-1 Pump & Valve module pipeline schematic diagram
Wash:
Use cleanser A to wash sampling pipeline, proceed in two phases: sampling needle
inner-wall and out-wall wash. Taking CH 1 as an example, the flow path is as following:
1. Cleanser A comes out of cleanser A package, through connecting pipeline via Valve
DZ9, Cleanser detector, Cleanser pump, Valve DZ10(normally open), Sampling
needle out-wall into Wash pool, and via DZ1(normally open), Waste pump into Waste
container;
2. Cleanser A comes out of Cleanser A package, through connecting pipeline via Valve
DZ9, Cleanser detector, Cleanser pump, Valve DZ10(normally close), then via Valve
DZ32, Counting chamber, Valve DZ31, Sampling needle inner-wall into Wash pool,
and via Valve DZ1(normally open), Waste pump into Waste container.
Rev-wash (Reverse-wash):
Process comes out the same as normal wash process, in order to make sure it is more
clean, to be called enhance wash.
70
AVE-764
Service Manual
Maintain:
The analyzer needs maintenance after daily operation. Click Quit icon on Microscopy
interface and select Quit and Maintenance in the pop up dialog to run maintenance wash
automatically. The maintenance wash is similar with reverse wash in flow path, only
except using maintenance cleanser and open Valve DZ8 not DZ9.
Spe-wash (Special-wash):
If stains and spots are found in Counting chamber, select Spe-wash, the process is similar
to Rev-wash only except using Cleanser B and open Valve DZ7 not Valve DZ9.
Sample:
During the Sampling operation, sampling needle will be pulled out of wash pool, get into
the sample tube, then the Valve of selected channel will be open automatically(such as
Valve DZ31 or DZ32), waste pump works, pump in and out three times in order to make
sure the sample is fully mixed, sample in and transfer into Counting chamber via selected
pipeline.
