Sensor för hydraulolja
This is the final documentation of the basis that can be the foundation of how to solve theproblem with leaking hydraulic oil in a shoe press at the company Albany InternationalAB in Halmstad, Sweden.The project has been performed at Halmstad University as a degree project commissionedby Albany International AB. The purpose of the degree project was to find a way ofdetecting the hydraulic leak of a shoe press. The reason is that the shoe press runsunattended during nights and weekends, this can cause an extensive decontaminationwork and production stop if leak. The hydraulic oil could be leaking in large amounts orslowly as a fine mist. The development of a working system that can detect a hydraulicoil leak and stop the machine before a large amount of hydraulic oil leaks out wouldconsiderably reduce the cost of the decontamination work. It would also reduce theinterruption time of the production. When the hydraulic oil is leaking as a fine mist andspreading in the facility, the risk of fire is much higher and will be reduced if detected intime.The outcome of the degree project is this document containing results of investigationsand a suggestion on how to make a prototype. In benefit of investigations, inquiry andtests the project group has been able to choose a suitable method of how to detect ahydraulic leak. The prototype has been tested in laboratory environment and showed agod ability to detect hydraulic oil.
