CONSTRUCTION
This
machine is of very simple and user friendly design. It
consist of a chamber for
tray washing . In
tray washing chamber tray is located on a suitable brackets.
Reciprocating motion is given to the tray, so as to expose
all the surfaces of tray to spray nozzles.
Tank of washing media is located below the chamber. A
magnetic separator (optional), Pump and filtration system is
mounted over the tank at the backside of washing chamber.
Drain of washing chamber is connected to magnetic
separator/OR to inlet of tank. Necessary electrical and pneumatic controls are
provided at a suitable location. Flow control valves are
used to regulate flow of washing media. A bypass valve is
provided to bypass the flow in the tank when no washing is
going on in respective chambers.
OPERATION
Tray
Washing :-
Operator
will open the door and load the tray in reciprocating
bracket. After loading the tray he will close the door and
will start the cycle. Once cycle is on spray will start from
nozzles and tray will start reciprocating. After preset time
flow will stop. Reciprocating motion will continue for some
time and after cycle time is over reciprocating will stop
and machine will give indication of cycle over. Operator
will open the door and will remove the clean tray and put
another one for washing.
FEATURES
1] MAGNETIC SEPARATOR :- (Optional)
The
drain of washing chambers is connected to magnetic
separator. Spent washing media after washing will be
directed to magnetic separator. Magnetic separator will
separate burr, dust from washing media and the same will be
collected in separate bin, tray. Burr and dust free washing
media will be collected in the tank.
2] FILTRATION SYSTEM :-
5
to 10 micron filter cartridges are placed in suitable
housing. High pressure pump will deliver the washing media
in filter housing. Filtration will take place
under pressure and filtered washing media will be sprayed on
components. Thus ensuring very high degree of washing
efficiency. (Millipore values up to 5mg can be achieved in
valve bodies)
3] NOZZLE ASSEMBLY :-
Tray is located in upside down position. As component is
located in a fixture in a specific orientation nozzles are
fixed in such a manner that it will cover all the pockets of the tray while
reciprocketing . From front side nozzles fixed on door will
clean the component from loading side. Nozzles are placed as
close as possible to the surface of component so as to get
maximum washing efficiency.
4] MIST COLLECTOR :-
(Optional)
Due
to high pressure of washing media and drying by compressed
air lot of mist is generated inside washing chamber. When
door is opened this mist will escape through the door. This
can pose serious problems to operator. To avoid this Mist
collector is provided on top of washing chamber.
