Abstract: A method and system for extending the service life of an x-ray tube wherein the coolant fluid which is circulated through a closed circulation system to remove heat generated by the x-ray tube and provide electrical insulation between anode connections and ground (and/or cathode connections) is regularly filtered and/or changed based on predetermined criteria. Provided for performing the filtering and/or changing is a cart which, preferably, is mobile, portable or otherwise easy and convenient to operate. The cart includes a new oil reservoir, an old oil container, various valves and a bidirectional pump for performing various functions. For example, the cart allows a technician or other skilled individual to connect the cart to a source of new oil for the purpose of filling its new oil reservoir container, this being known as the FILL mode.

In addition to the fluid change, an on-line fluoroscopy is also regularly performed based on a separate set of predetermined criteria.

Abstract: An internally-mounted apparatus for high speed oil changes, pre-lubrication and engine cleansing/flushing is disclosed. The apparatus is specially designed to be easily configured as necessary to perform the above-mentioned operations. The apparatus includes a valve and a reversible pump coupled between the oil drain opening and a multi-way valve. The multi-way valve can be configured such that 1) old oil can be pump out of the engine and into an external storage container, 2) out of an internally-mounted new oil container and into the engine, and 3) from the oil drain opening to an oil fill opening for purposes of circulation. The pump and the valves can be electronically-controlled for operator convenience.
