Overview The non-contact seal of the engine's rotating shaft often uses a graphite seal ring to separate oil and gas. Due to the structural reasons, the graphite ring has a certain amount of leakage in practical applications. The leakage value of the graphite sealing ring is also a key indicator for determining the quality of the graphite sealing ring. The sealing effect of the sealing ring is also crucial for the quality of the engine. Impact. • For the important role of the seal ring, the construction of the seal ring seal tester can solve the following problems: • It can inspect the sealing performance of seal rings from different manufacturers, which is good for selecting excellent manufacturers. • Can test different types of sealing rings, which is good for model screening, and device optimization and update • Verifiable fatigue of the seal ring • When the equipment is faulty, it can help to check if the fault is caused by the sealing condition of the seal ring • Quantitative test data makes test conclusions more credible solution The composition of the seal tester is shown in the following figure: including drive system, air system, oil system, installation and support system, control and data acquisition system. Drive System The power system is a power source that provides a stable rotary rotation for the test device. Because the speed required by the seal test device can be as high as 25000r/min, and the ordinary motor is difficult to reach its speed requirement; therefore, the gear speed increaser is used to increase the output speed of the motor to ensure that the input speed of the seal test device meets the requirements. The system comprises: a main motor, a gear speed increaser, a coupling, and a torque sensor. Air system The air system provides clean air with temperature and pressure to meet the requirements of the sealing test device. According to the requirements of the test conditions, the air system supplies the gas source of the two working conditions to the sealing test device through the transmission pipeline: one is a normal temperature gas; the other is a high temperature temperature. . Including: gas source equipment, gas source purification equipment, heaters, valves, sensors, pipes and pipe fittings. 2. Oil system The oil system is used to supply lubricating oil to the gearbox and test equipment, reduce friction and cool, and remove the heat generated by the rotating friction of the equipment. Including gear speeder oil system, test section and test piece oil system. 3. Installation and support system The mounting and support system primarily provides installation and rapid alignment of the drive system. The mounting platform is fixed to the test room floor. Because the center height of each device in the drive system is inconsistent, the center must be adjusted to a uniform height through the mount to ensure the alignment of the shaft. 4. Control and data acquisition system This part mainly includes: on-site power distribution cabinet, on-site electric control cabinet and frequency conversion cabinet, instrumentation, PLC control cabinet, monitoring computer. The operating status and test data of each system in the field are collected by PLC, and the relevant control and calculation are completed inside the PLC, and the collected sensor data is uploaded to the operation monitoring computer, and the test system is operated on the computer, and the data is retained. .
