UEA has successfully built the most advanced and efficient hydraulic swivel leakage detecting system in the industry through company investment and team efforts. The test system is designed to be an accurate instrument for detecting potential hydraulic leakage inside the swivel assembly under specified pressures, and also to measure the swivel rotating torque. Finishing up the test system build is a big step forward for hydraulic swivel product development and production at UEA. It has laid a solid foundation to meet product quality assurance for UEA's hydraulic swivel production.
The test system consists of test stand assembly, hydraulic power unit with status LED display and electric motor control panel, transducers and data acquisition devices and a laptop computer and control program. In addition, an in-line contamination monitor (ICM) is integrated into the hydraulic circuit to real-time monitor the test oil cleanliness levels and thus to ensure the test oil meets ISO 4406 cleanliness code levels during the testing process. The test stand is equipped with both low pressurized air test medium and high pressure hydraulic oil test medium to detect any potential internal swivel leakage.
This computer-based instrumentation and control system is readily adaptive to meet our customers' various testing requirements based on different swivel design specifications. For quality assurance, UEA will conduct 100% hydraulic swivel testing prior to shipping. The test system records and stores time-stamped test data in spreadsheets, which will be provided to our customers with the delivery of hydraulic swivels.
