The invention discloses a multi-physical quantity measurement test device for rotating shaft seals, which comprises: a housing, the housing defines an installation cavity, and the housing is provided with a measurement window; a first sleeve; a second sleeve, the second sleeve is sleeved On the outer surface of the rotating shaft, the intermediate ring, the intermediate ring is located between the first sleeve and the second sleeve to divide the installation cavity into the first chamber and the second chamber; the speed detection mechanism, the speed detection mechanism detects through the measurement window The rotation speed of the intermediate ring; the displacement detection mechanism, which detects the displacement of the intermediate ring in the axial direction of the rotating shaft through the measurement window; the temperature detection mechanism detects the temperature of the intermediate ring through the measurement window; the flow detection part. Thus, through the multi-physical quantity measurement test device of the present application, the rotational speed of the intermediate ring, the displacement in the axial direction of the rotating shaft and the temperature can be measured in real time, so as to understand the real-time state of the sealing ring, and then obtain the rotational speed of the intermediate ring and the displacement in the axial direction of the rotating shaft. Effects of axial displacement and temperature on the sealing performance of the intermediate ring.
Description
technical field [0001] The invention relates to the field of measurement tests, in particular to a multi-physical quantity measurement test device for rotary shaft seals. Background technique [0002] The mechanical seal is a low-wear, long-life, high-reliability seal for rotating shafts. Due to its good comprehensive performance, mechanical seals have been widely used in aerospace, petroleum and petrochemical fields. The mechanical seal with an intermediate ring structure can make the low (high) speed seal end faces have a relatively high (low) relative speed, so that the end faces of the mechanical seals at all levels can maintain a reasonable relative speed, and then make the dynamic pressure non-contact mechanical seal Can work stably. [0003] In the related art, after the seal assembly with the intermediate ring is installed on the rotating shaft, due to the special position of the intermediate ring seal, during the rotation of the rotating shaft, the speed of the in...
