Rexroth offer a very useful accessory designed to assist with hydraulic system fault finding and system commissioning. The manual override switch provides a means of actuating CETOP 3 solenoid valves without the need for tools required to operate the standard solenoid actuator. In addition the manual override, which can be fitted to the current range of Rexroth solenoid valves, provides a visual indication of the solenoid state. The manual override can be fitted to both single and double solenoid valves.

Supported by Bosch Rexroth and its extensive range of fluid power, mechanical and electronic components Yarl Hydracentre are able to maintain and develop your fluid power systems providing extensive diagnostic services, maintenance programmes, spare part provision and system design.

Yarl Hydracentre's skilled team of fluid power technicians and engineers supported with a broad range of diagnostic tools are able to provide system analysis, provide cost effective and reliable solutions to support and develop your fluid power and related production processes.

Diagnostic tools can be applied to your systems capable of measuring and logging real time pressure, flow and temperature data identifying data spikes occurring in a fraction of a second. System faults not normally identified with conventional diagnostic tool can be isolated and eliminated.

      Further diagnostic tools are available to measure fluid cleanliness, element composition and water content. This data interpreted by our skilled engineering teams can find the root cause of intermittent or repetitive system faults evading diagnosis from conventional tools and processes.   

Backed up by the Bosch Rexroth Bradford based repair, test and training facilities we are able to provide component repair and rebuild services at fixed costs and lead times. For those emergency breakdowns these services can provide short lead time component exchange recovering your production cost effectively.

BAE Systems Submarine Solutions Dockside Test Organisation, based at Barrow-in-Furness, Cumbria identified the requirement for a C02 Vaporiser Gas management system for use during the commissioning phase of the build for Astute Class Submarines.

The critical requirement of the process was to ensure only CO2 vapour is delivered to the submarine at temperature and pressure parameters which are very close to the state in which CO2 can exist in both the liquid and gas state.

Yarl Hydracentre engineers used their knowledge of fluid mechanics to clearly define these parameters for the range of test conditions expected to be experienced during the commissioning phase of the submarines. Having established the project scope, the fluid and gas circuits could be designed and the control logic and parameters defined.

The design employed a number of pressure and temperature sensors to provide inputs to the control plc and, in conjunction with a gas vaporiser, output signals sent to control valves ensuring only CO2 gas is output from the plant.

The plant included a scavenge pump designed to extract gas from the liquid CO2 bottles when the internal pressure dropped below the required output pressure. The pump automatically maintains the required gas output pressure using proportional valve technology in conjunction with the system plc. The Co2 bottle pressures are monitored and, when empty, the system automatically changes the supply to a second bottle providing BAe Systems with the 4 hour continuous delivery of gas they required.

The complete system was assembled in a compact cabinet at Yarl Hydracentre's Barrow facility. Following Yarl Hydracentre's own commissioning and test programme BAe Systems Dockside Test Facility engineers witnessed a comprehensive test programme at the Barrow facility which concluded with a full simulation of BAe's gas generation process, proving the full functionality of the plant.

Yarl Hydracentre is pleased to support this summer's headline exhibition, 'BBC Walking with Dinosaurs' at the Beacon, Whitehaven.

The BBC Walking with Dinosaurs Exhibition, based on the award-winning BBC TV series, looks at the science behind the series and tells you more about Dinosaurs and how they lived.

This blockbuster exhibition will include original scale models used to produce the digital animations, full sized Dinosaur replicas including the skull of Tyrannosaurus and Triceratops, as well as large format graphics from BBC originals and computer interactive games.

In conjunction with Sealey compressors Yarl Hydracentre are providing the compressed air systems used to power an animated exhibit allowing visitors to bring a dinosaur to 'life'.

The exhibition runs from the 11th June to the 4th September 2011.
