METHOD FOR DETECTION OF A MALFUNCTION RELATED TO A FLUID AFFECTED COMPONENT IN A PISTON MACHINE
First Claim
1. A method for detection of a leak in a fluid affected component of a piston machine, the method comprising:
- obtaining a vibration signal from a vibration sensor disposed proximate to at least one valve block of the piston machine, wherein the vibration signal comprises vibration generated by valves in the valve block;
presenting the obtained vibration signal for analysis by at least one of a human or a computer;
analyzing the obtained vibration signal with respect to revealing a malfunction related to a fluid affected component of the piston machine; and
selecting the obtained vibration signal emitted from the valve block during the closed periods of the valves for presentation.

Abstract
A method for detection of a leak in a fluid affected component of a piston machine includes obtaining a vibration signal from a vibration sensor disposed proximate to at least one valve block of the piston machine. The vibration signal includes vibration generated by valves in the valve block. The method further includes presenting the obtained vibration signal for analysis by at least one of a human or a computer, analyzing the obtained vibration signal with respect to revealing a malfunction related to a fluid affected component of the piston machine, and selecting the obtained vibration signal emitted from the valve block during the closed periods of the valves for presentation.

11. A piston machine, comprising:
-
a valve block having valves disposed therein; a crankshaft; a vibration sensor disposed proximate to the valve block; a computer in communication with the vibration sensor, wherein the computer is configured to select a vibration signal emitted from the vibration sensor during closed periods of the valves and, using at least the vibration signal, determine a malfunction related to a fluid affected component of the piston machine. - View Dependent Claims (12)
