Early warning and protection for heat exchange systems
First Claim
1. A method for warning an operator about a malfunction in a pump and/or engine of a marine vessel or another suitable device or equipment, including a malfunction in a heat exchange system of the engine for a marine vessel or other suitable non-marine vessel, as well as other suitable non-marine vessel such as industrial equipment and circulation and industrial applications, characterized in that the method includes the steps of:
- comparing a sensed pressure differential at a sensed RPM when the pump/engine is running to a learned database having a pressure differential versus RPM curve; and
providing an indication to the operator when there is a change in the relationship that exceeds a predetermined relationship.

Abstract
Method and apparatus are provided for warning a user or operator about a malfunction in a pump and/or engine of a marine vessel or another suitable device or equipment, featuring steps of: comparing a sensed pressure differential at a sensed RPM when the pump/engine is running to a learned database having a pressure differential versus RPM curve; and providing an indication to the operator when there is a change in the relationship that exceeds a predetermined relationship. The apparatus may include an active intelligence unit or module for making the comparison and providing the indication according to the invention.

29. A method for warning the user about a malfunction in a pump/engine of a marine vessel or another suitable device or equipment, including a malfunction in a heat exchange system of the pump/engine for a marine vessel or other suitable non-marine vessel, as well as other suitable non-marine vessel such as industrial equipment and circulation and industrial applications, characterized in that the method includes the steps of:
-
sensing a relationship between two parameters when the pump/engine is running, including a pressure differential and the RPMs of the engine, the pressure differential being measured between an inlet and outlet of a water cooling system of a pomp in the engine; and providing an indication to the user when there is a change in the relationship that exceeds a predetermined relationship. - View Dependent Claims (30, 31)
