A Production Test & Validation Machine that was developed to check that manufactured Compressor Units operated within pre-determined acceptance parameters.
The machine undertook a series of sequential test operations including pressure burst test, helium leak testing, voltage / current measurement, noise (vibration) analysis prior to automatically filling the compressor with the relevant quantity of oil.
The equipment utilised a programmable logic controller for the sequencing of the ‘switched’ operations, a microprocessor unit for the measurement analysis and an industrial visual display unit for status / test result indication. All relevant testing / comparison parameters and oil fill times were automatically selected upon entering of the compressor model type via the machine’s integrated alpha / numerical keyboard.
This Cold Engine Test Rig was developed to enable
the relevant running performances of fully refurbished automotive engines to be compared against specified parameters. The engines were ‘turned over’ by the utilisation of an electrical drive motor that was programmed to run at different speeds throughout the duration of the test cycle.
The test rig was configured to sequentially monitor the compression pressures of 4, 5 & 6 cylinder engine variants whilst simultaneously ensuring that both oil / water pressures were within
pre-determined acceptance limits.
This twin station test facility was developed to check both the leakage integrity and integral valve function / operation on two variants of an assembled automotive Rocker Cover component.
Whilst the leak testing operation was undertaken using positive pressure, the valve function utilised vacuum to monitor
for valve closure within a specified time period.
By accurately monitoring the characteristics of the valve closure, it was also possible to determine the existence of the spring within the rocker cover’s internal diaphragm valve assembly.
Each test station incorporated a ‘component type’ detection system that was incorporated within the machine’s control to automatically engage the correct seal units. A fully automated component unload system was fitted to both of the test stations, which discharged each successfully tested part on to a conveyor positioned at the rear of the facility.
