With the petroleum, petrochemical and other industries rapid development requires mechanical seal with high stability, high reliability and long life, experimental techniques for mechanical seals put forward higher requirements . Thesis, Zhejiang University of Technology Laboratory of Chemical Process mechanical seal as the background, in order to meet the mechanical seal multipurpose testing research needs to carry out a variable-speed control mechanical seal experiment system . The main contents are: First, according to domestic and mechanical seal technology trends , the main reason for the failure of the mechanical seal mechanical seal and related experimental system based on the analysis to determine the experimental system design goals. According to the experimental system design requirements, determine the experimental system's overall design, the experimental system is divided according to function as mechanical body , testing electrical parts and software systems in three parts. Secondly , to carry out a mechanical body and test rig electrical control system design. Based on experimental simulation sealed condition parameters, as well as the overall layout of the bench power, transmission and seal chamber design, using hydraulic scheme to achieve a sealed chamber variety of media , continuous fluid supply regulator system design , the establishment of the mechanical seal test bench ; based on inverter technology , to achieve a systematic experimental process variable functional design and conduct of temperature, friction torque , pressure and seal gap measurement solutions such as the design and selection of sensors to achieve a multi-parameter measurement function testing system design . Then , to carry out the software system design . According to the experimental system functional requirements of the system based on LabVIEW to achieve automatic control, data acquisition, data display, data storage, and historical data query functions , and details of the test system software, the basic process and implementation methods are given key specific design features and block diagram . Finally, based on the establishment of a mechanical seal test platform , launched the start contacting mechanical seal Experimental testing, inspection of the experimental system operability.
