Abstract
A leakage detection system is described, with the leakage detection system comprising a fluid chamber (8) containing a first fluid, and a sealing element (12) located between the fluid chamber and a second fluid chamber (15), said sealing element (12) being adapted for sealing the first fluid in the fluid chamber (8), and the second fluid chamber (15) being located adjacent the sealing element and containing a second fluid. The leakage detection system further comprises a detection unit (19) in fluid connection with the second fluid chamber, said detection unit being adapted for detecting leakage by evaluating a property of the second fluid, with said property being affected by first fluid leaking into the second fluid.
Claims16
A pumping apparatus comprising
- a pump chamber containing a first fluid, the pump chamber comprising an inlet and an outlet;
- a piston reciprocating within the pump chamber;
- a sealing element for sealing the piston relative to the pump chamber's housing;
- a second fluid chamber located adjacent the sealing element, said second fluid chamber containing a second fluid,
- a detection unit in fluid connection with the second fluid chamber, the detection unit being adapted for detecting leakage by monitoring a property of the second fluid, with said property being affected in case of first fluid leaking into the second fluid.
A method for detecting leakage of a sealing element in a pumping apparatus comprising:
- a pump chamber containing a first fluid,
- a piston reciprocating within the pump chamber, wherein the sealing element is adapted for sealing the piston relative to the pump chamber's housing, and
- a second fluid chamber located adjacent the sealing element, said second fluid chamber containing a second fluid,
- the method comprising:
- a) supplying a flow of a second fluid in a second fluid chamber located adjacent the sealing element;
- and
- b) detecting leakage by evaluating a property of the second fluid, said property being affected when first fluid leaks into the second fluid.
