Abstract: Disclosed is an expansion tank having an internal cavity separated by a flexible diaphragm to form an upper pressurized gas portion and a lower pressurized fluid portion, and an indicator positioned at an upper part of the expansion tank in communication with the contents of the upper pressurized gas portion. The indicator is configured so as to display a first color if the operating conditions are normal in the pressurized gas portion, and a second color if the amount of moisture detected in the pressurized gas portion greater than or equal to a predetermined amount. Further disclosed is a method for detecting whether there is an excessive amount of moisture in a pressurized gas portion of an expansion tank by allowing pressurized gas from the pressurized gas portion to come into contact with the indicator, and viewing the color displayed by the indicator. As such, the tank can be simply visually inspected to determine whether there is a potential failure in the tank.

Abstract: The invention relates to a method of condition-monitoring hydraulic accumulators. The gas content of the accumulators is monitored by the gas volume being calculated on the basis of the weight and working pressure of the accumulators. The working pressure of the accumulators and a relevant operational history are recorded with an electronic logging system which stores data for use in connection with condition-based maintenance of the accumulators.
