High-pressure test platform for testing leakage of fuel pump valve arrangement

Abstract

A high-pressure test platform (10) for testing leakage of a valve arrangement in a component, said high-pressure test platform (10) comprising a high-pressure test line (11) connected at one end to a source of pressurised test fluid (24) and having at the opposite end a connector (13) for fluid coupling to a port of said component; wherein said test line (11) further comprises, serially connected from the connector end, a test chamber (14) having a predefined volume and a first block valve (18); wherein a pressure sensor (16) is arranged to determine a pressure in a test section of the test line (11) between the connector (13) and the first block valve (18); wherein a control unit (32) is configured to monitor the pressure in said test section by means of said pressure sensor, and detect pressure decay; characterized in that a first buffer chamber (20) having a predetermined volume is serially connected in the test line (11) between said first block valve (18) and a second block valve (22), separating said buffer chamber (20) from the source of pressurised test fuel (24).
