摘要： A system for measuring wear of a radial lip seal arranged circumferentially over a rotatable axle A sensor is configured to measure the wear of the radial lip seal by measuring the distance between the sensor and the radial lip seal. The wear of the radial lip seal corresponds to the distance of the radial lip seal from the sensor. The distance is measured between the sensor and the outer diameter of the radial lip seal. The sensor is configured for dynamic measuring of the radial lip seal and static measuring of the radial lip seal and to predict the replacement of the radial lip seal. Static measuring refers to the measurement performed by the sensor when the rotatable axle is stationary and dynamic measuring refers to the measurement performed by the sensor when the rotatable axle is rotating.

摘要： A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.

摘要： Methods and apparatus are provided for an improved system for early detection of a fault in an EPS system for a vehicle. The apparatus includes a steering gear assembly including a temperature sensor and a pressure sensor for sensing within the steering gear assembly. A controller determines a relationship between the temperature value and the pressure value, and also determines whether the relationship is within a threshold of a reference relationship. The controller can provide an indication or message on a display when the relationship is not within the threshold of the reference relationship. The method includes monitoring a temperature and a pressure associated with an electronic power steering system for a vehicle during operation of the vehicle and determining a relationship between the temperature and the pressure. A fault indication or message is presented on a display when the relationship exceeds a threshold value from a reference relationship.
