Abstract:
A method for testing a plurality of fire hoses having respective service test pressures and the test apparatus therefor wherein each hose is required to maintain a test pressure for a specified duration to pass the test. The test pressure is proportional to the service test pressure. Each hose is coupled to a respective hose fitting of a respective branch test conduit. Each branch test conduit includes an isolation valve, a pressure transducer, and a hose fitting downstream of the isolation valve. A variable frequency-variable speed controls a motor which drives a positive displacement water pump supplying water to and pressurizing a water header conduit and a plurality of branch test conduits interconnected therewith. An algorithm applied to the error signal for a respective hose line generates a pump speed command limited by the controller to regulate the rate of increase of pump output pressure.
