Silicone And Rubber Component Replacement - Afikim Afi-lite Plus User Manual

The AfiFo milk meter body is a plastic container made up of three main parts:
•
The Upper Cover and Inlet Port:
Milk enters the main chamber through the inlet port.
•
The Main Chamber:
Milk fills the mid section while the valve is closed (in upper
position).
•
The Lower Cover and Outlet Port.
When the solenoid is energized, the valve opens and releases the
milk. The milk flows through the lower part and outlet port to the
milk line.
Within the AfiFlo milk meter body are:
•
Three electrodes.
•
A cylindrical valve, which is also an overflow tube.
•
A silicon diaphragm.
The electrodes detect the milk level. A signal prompts the opening and draining
of the central chamber. The electrodes also sense the milk's conductivity. The
precise amount for measurement is not predetermined, and measured milk
portions may vary from 180–250 cc.
When the solenoid valve is energized, vacuum from the solenoid line causes the
silicon diaphragm to pull the valve down. This releases a portion of the milk.
Depending upon local configurations, attached to the exterior of the milk meter
body may be:
•
A fat sampler attached to the milk outlet. Information about the fat
sampler follows, in this chapter.
•
A single vacuum shut-off valve. Upon cluster removal, this valve
shuts the vacuum to the cluster.
•
A triple diaphragm valve, side mounted, back-flush assembly. This
assembly allows for a back-flush between the milking of cows. The
back-flush is advantageous in that it decreases the likelihood of
cross-contamination of cows between milkings. Upon cluster
removal, one of the three valves shuts off vacuum.

Silicone and Rubber Component Replacement

Replace the following four components once a year:
•
The upper and lower silicone gaskets.
Note: Order two of these gaskets for each milk meter.
•
The silicone valve gasket.
