Oil filter with impending and full-bypass indicators
A removable oil filter system includes an oil filter mount, an oil filter element removably connected to the oil filter mount, an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, and a full-bypass indicator in fluid communication with the oil filter mount. The impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system. The full-bypass indicator is capable of reporting a full-bypass condition of the oil filter system.
1. A removable oil filter system, comprising:
an oil filter mount on a gearbox;
an oil filter element removably connected to the oil filter mount;
an oil pressure regulator in fluid communication with the oil filter and the oil, wherein the oil pressure regulator comprises a temperature bulb, an oil pressure transducer, and first and second transfer tubes, wherein the first transfer tube is an oil output and the second transfer tube is an oil flow bypass;
an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, wherein the impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system; and
a full-bypass indicator in fluid communication with the oil filter mount and capable of reporting a full-bypass condition of the oil filter system, wherein the impending-bypass indicator and the full-bypass indicator indicate whether a filter and oil need to be replaced or if the oil requires flushing due to contamination in the gearbox.
2. The system of claim 1 , further comprising a display, an on-board computer monitoring system, or a remote computer monitoring system communicably coupled to the impending-bypass indicator, wherein the impending-bypass indicator is configured to transmit the impending-bypass condition to the display, the on-board computer monitoring system, or the remote computer monitoring system.
3. The system of claim 1 , further comprising a display, an on-board computer monitoring system, or a remote computer monitoring system communicably coupled to the full-bypass indicator, wherein the full-bypass indicator is configured to transmit the full-bypass condition to the display, the on-board computer monitoring system, or the remote computer monitoring system.
4. The system of claim 1 , further comprising an oil pressure regulator in fluid communication with the oil filter mount.
5. The system of claim 1 , further comprising an oil pressure transducer in fluid communication with the oil filter mount, wherein the oil pressure transducer is capable of converting an oil pressure measurement to an electrical signal.
6. The system of claim 1 , further comprising one or more transfer tubes in fluid communication with the oil filter mount, wherein the one or more transfer tubes comprise an oil input tube the oil filter system, an oil output tube the oil filter system, or a oil bypass tube.
7. A removable oil filter system for an aircraft, comprising:
an oil filter mount on a gearbox, reduction gearbox, pressurized gearbox, or main rotor gearbox of the aircraft;
an oil filter element removably connected to the oil filter mount;
an oil pressure regulator in fluid communication with the oil filter and the oil, wherein the oil pressure regulator comprises a temperature bulb, an oil pressure transducer, and first and second transfer tubes, wherein the first transfer tube is an oil output and the second transfer tube is an oil flow bypass;
an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, wherein the impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system that indicates the need to change of fluid and filter; and
a full-bypass indicator in fluid communication with the oil filter mount and capable of reporting a full-bypass condition of the oil filter system,
wherein the impending-bypass indicator indicates whether a filter and oil need to be replaced and
wherein the full-bypass indicator indicates that the indicate filter, oil, and entire lubrication needs to be replaced due to contamination in the gearbox, reduction gearbox, or main rotor gearbox of the aircraft.
8. The system of claim 7 , further comprising a display, an on-board computer monitoring system, or a remote computer monitoring system communicably coupled to the impending-bypass indicator, wherein the impending-bypass indicator is configured to transmit the impending-bypass condition to the display, the on-board computer monitoring system, or the remote computer monitoring system.
9. The system of claim 7 , further comprising a display, an on-board computer monitoring system, or a remote computer monitoring system communicably coupled to the full-bypass indicator, wherein the full-bypass indicator is configured to transmit the full-bypass condition to the display, the on-board computer monitoring system, or the remote computer monitoring system.
10. The system of claim 7 , further comprising an oil pressure regulator in fluid communication with the oil filter mount.
11. The system of claim 7 , further comprising an oil pressure transducer in fluid communication with the oil filter mount, wherein the oil pressure transducer is capable of converting an oil pressure measurement to an electrical signal.
12. The system of claim 7 , further comprising one or more transfer tubes in fluid communication with the oil filter mount, wherein the one or more transfer tubes comprise an oil input tube the oil filter system, an oil output tube the oil filter system, or a oil bypass tube.
