The PROLIFIC Endurance Tester for Exhaust Seal for Durability Test of Exhaust Gasket (Seal) consists of a stainless steel pipe on which the seal under test shall be held rigidly, another steel pipe with a flange for holding the seal on the first pipe through a spring loaded flexible coupling, and a mechanical arrangement to oscillate the second pipe to an angle of Â± 3Âº (adjustable to Â±4Âº, Â±5Âº or Â±6Âº, if desired) about a horizontal axis passing through the centre of curvature of the outer surface of the seal. The frequency of oscillation is 8 Hz (480 cpm). The oscillating mechanism is complete with an electric motor & gear box and eccentric mechanism for the desired oscillation. The equipment has a provision for passing hot air through the pipe on which the seal under test is mounted. The air is provided by a blower fitted on the equipment and heated through burning a mixture of LPG gas and oxygen gas. [The LPG gas cylinder and oxygen gas cylinder are provided by the purchaser.] Rotameters are fitted on the equipment to measure and manually control flow of oxygen and LPG gas to control temperature of the seal as indicated on the temperature indicator provided on the equipment. The number of oscillation is recorded on a pre-set type of counter with two pre-set relays.
