Electronics, mechatronics & hydraulics Dynamic test bench for mechanical oil pumps


Hydraulic end-of-line testing of a mechanical oil pump for gearboxes for cooling and oil pressure generation. The test bench is equipped with several stations to reduce the machine cycle to a minimum.
The test specimens are automatically fed to the machine by a belt system. Within the test stand a gripper handling system transports the pumps.
In the measuring station the test takes place. The fully automatic contacting of the test item within the stations takes place on an easily exchangeable workpiece carrier.
The test specifications are made by a database-based, flexible test plan system. The individual test steps can be configured in any order and number, as well as with different parameter specifications to a flow chart. Due to the central database on a separate server PC the simple parallel connection of several test benches of the same type can be carried out. All results can be automatically stored and archived on the server.
