Wash Module
Description
The system consists of one or
two wash heads connected flexibly to a service unit which has a
cleaning fluid tank, high pressure pump, low pressure pump, mist
suction and separation device, and two-stage filters. The high
pressure is generated by a two-cylinder radial piston pump,
generating approximately 100 bar alternately in two separate
supply ports. These ports are connected to jets within the
fixture such that the component receives alternate pulses from
opposite ends at about 50 Hz. Some jets are directed to
spin the component while the main jets are directed axially at
each end of the component. An exhaust port is connected to an
annular ring around the head of the component. The exhausted dirty
cleaning fluid, or air and cleaning fluid, is collected by the
suction unit which provides separation of the cleaning fluid and
air, and low-level centrifuge to remove heavy debris from the
cleaning fluid. The fluid passes from the centrifuge to a
settling chamber. From here it is then circulated by the
low-pressure pump through two cartridge filters (10 micron and 5
micron).
Wash Module Service Unit
Operation
The component to be cleaned is placed face downwards in the
fixture part of the wash head, automatically or manually
depending upon the application. The fixture is clamped shut
by a pneumatic cylinder situated below the wash unit. A
safety guard must then be closed if the unit is manually
loaded.
The Wash Cycle
The wash sequence is controlled by a PLC and consists of the following steps
- Clamp
- High Pressure Wash
- Air Blast
- Unclamp
A wash time of 10 seconds followed by an air blast of 5 seconds generally gives good results. One service unit can supply two wash fixtures, giving two parts every 20 seconds.
