HPF 300 High Pressure Wash Module

Description

Designed primarily for diesel injection system fuel rails, the system is capable of cleaning both spherical and linear rails and has been adapted for other components. Oil at varying pressures is flushed through the components and a lance arrangement directs high pressure oil at specific locations where intense cleaning is required. Rails with greatly varying internal orifices may be tested with no modification to the system.
Suitable for use in a clean room environment, with the power pack unit, housing the main fluid reservoir with filtration, external to the room. The machine has two independent stations each capable of running a separate product simultaneously. The flexible cycle start sequence will allow twin load/unload, individual load/unload or single load/unload. The NC control of the lance allows static and dynamic linear and rotational positions to be set and dynamic interpolation between linear and angular positions to be achieved.
The frame is of stainless steel construction with tooling blocks etc being electro-plated as appropriate. The flushing machine has a footprint of approximately 1.3m x 1.3m excluding the power pack

HPF300 High Pressure Flushing Machine

Operation

The component to be cleaned is loaded into one of the fixtures where it is hydraulically clamped once the door has closed and interlocks activated. The pre selected automatic flushing sequence then controls the linear and angular position of the lance, the oil pressures, the air and oil direction supply valves. The system executes each step in the sequence sequentially until it reaches the end when flushing with factory air can be carried out to aid drying/purging of the component.

The Flushing Sequence

Controlled by a PLC, a flushing sequence may be constructed in Excel or directly on the machine to clean a component in the most efficient manner. The open or closed state of each of the air, oil and exhaust valves may be set independently, the linear and angular position of the lance and the pump pressures. A sequence may have up to 64 steps. Existing steps are copied from the machine for editing off line and then reloaded using a memory card.
