摘要
A fatigue testing system for a liquefied petroleum gas cylinder and a testing method for the fatigue testing system, relating to the technical field of fatigue testing of liquefied gas cylinders. The testing system comprises a high-pressure storage tank, a first compressor, a second compressor, a low pressure buffer tank, and a controller; the high-pressure storage tank is connected to the low pressure buffer tank by means of a heat exchanger, a one-way valve, the first compressor, and a first filter; the low pressure buffer tank is connected to a test piece by means of a third solenoid valve, and the test piece is connected to the high-pressure storage tank by means of a first solenoid valve; a second solenoid valve, the second compressor, and the third solenoid valve are connected in parallel; a PLC controller is used as the controller, and control relays of a pressure sensor, the solenoid valve, and the compressors are electrically connected to the controller. According to the testing system, the test gas is not only reused, but air charging and venting is also achieved by means of automatic control, the fatigue testing of the test piece under an operating environment can be simulated.
