To pressure test a hydraulic hose, connect it securely to a hydraulic pressure testing machine, ensuring all fittings and connections are tight. Gradually increase the pressure to the hose's rated maximum pressure, monitoring for any leaks or deformations, and maintain this pressure for a specified period to confirm its integrity.
To perform a hydraulic pressure test, fill the system with a non-compressible fluid, usually water, and pressurize it using a hand pump, motorized pump, or other pressure source to the required test pressure. Monitor the system for a specified period, checking for pressure drops or leaks that indicate potential issues.
The principle of a hydraulic pressure testing machine involves using a liquid, typically oil or water, to apply pressure to a component or system to test its strength, integrity, and leak resistance. By increasing the hydraulic pressure within the system, the machine can simulate operational conditions and identify potential points of failure or weaknesses in the material or assembly.
The proof pressure test for hoses is a procedure used to ensure the integrity and reliability of a hose by subjecting it to a pressure higher than its maximum operating pressure, typically 1.5 to 2 times higher. This test verifies that the hose can withstand extreme conditions without leaking, deforming, or failing.
