3. Center Manifold
The optional center manifold is used to clean very narrow-diameter, hollow, long parts
whose interior is inaccessible to the washing solution. Examples of such parts include
gun barrels, long pipes, and turbine pumps.
The center manifold oscillates vertically inside the part as the part rotates in the center
of the turntable. The center manifold cleans the interior as the power blast manifold
(PBM) cleans the exterior.
3.1. Theory of Operation
A superstructure on the reinforced roof of the washer cabinet houses the center
manifold , as shown in the following figure. The center manifold consists of a vertical
manifold tube the length of the work height of the washer, with 2 wash nozzles located
horizontally and connected to the lower end. The tube is guided through a pair of
bushings in the cabinet roof. The tube is raised and lowered by a roller chain and
carriage, which are driven by a gear motor.
Wash solution is piped to the vertical manifold tube through a hose attached to the back
of the cabinet roof. Optionally, an extra tube may be attached to the vertical manifold
tube for carrying rinse water to a pair of rinse nozzles on the lower end of the manifold.
Flexible tubing is connected to the hose to carry rinse water. The fluid flow for the
center manifold is provided from a tap off the flow to the power blast manifold (PBM).
Door Lock. The center manifold system incorporates an additional feature on the
standard washer to help prevent accidental damage to the vertical manifold tube or
parts on the turntable. An electrically actuated solenoid locks the washer cabinet door
closed during operating cycles to prevent accidental opening with the center manifold in
the down position. The door remains locked until the manifold returns to the
home
position. The lock functions automatically whenever the center manifold system is used
(in manual
and automatic modes).
Power is required to unlock the door. In the event of a power failure, or if power is
turned off to the machine, the door-lock solenoid will de-energize and lock the door.
The lock can be manually by-passed by pushing up the small pin that protrudes below
the solenoid lock box and opening the door. This will probably require the assistance of
another person. Be sure the manifold is in the
home position before performing this
procedure.
