Problems solved by technology

After investigating the operation status and failure causes of the centrifuges of the PTA units of Sinopec and PetroChina's subsidiaries, it was found that the centrifuge failures were mainly concentrated in the two aspects of vibration and mechanical seal leakage, which made the centrifuge in the production process. Fault shutdown and maintenance are relatively frequent, which seriously affects the improvement of enterprise production efficiency

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like figure 1 As shown, a test bench for testing the sealing performance of a heavy-duty pressure centrifuge includes a mechanical system, a control system, and a test and analysis system. The mechanical system is connected with the control system, and the control system is connected with the test and analysis system, and the test and analysis system tests and analyzes the running performance of the sealing components. The two frequency conversion and speed regulation digital display motors 1 of the mechanical system are respectively connected by conveyor belts and drive the rotor 17; one end of the bearing is connected with the rotor 17, and the other end of the bearing is connected with the housing seal 5 and the self-locking chuck structure 6. The multi-position bearing seat 2 and the adjustable eccentric excitation ring 3, the multi-position bearing seat 2 ...

Abstract

The invention belongs to the field of chemical equipment, and relates to an experimental device for testing the sealing performance of a heavy-duty pressure centrifuge. The equipment includes a mechanical system, a control system, and a test and analysis system. The mechanical system is connected with the control system, and the control system is connected with the test and analysis system. The test and analysis system tests and analyzes the operational performance of the sealing components. The invention is a test platform integrating monitoring and diagnosis, which can test the running performance of the sealing components, can monitor the leakage of the components and the vibration of the sealing shaft in real time, and can accurately measure the vibration of the bearing, the vibration of the mechanical seal and the temperature rise. Failure parameters, intelligent decision-making can be used to find out the cause of the failure. The invention provides data and theoretical reference basis for the production and manufacture of the heavy pressure centrifuge, the quality inspection of the sealing performance, and the performance technology upgrade of the sealing system, and has important engineering application value.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and relates to an experimental device for testing the sealing performance of a heavy-duty pressure centrifuge. Background technique [0002] Because heavy-duty pressure centrifuges can realize continuous production and can continuously process media with various concentrations, different flow rates and various chemical components, they are widely used in petrochemical enterprises, coal, environmental protection and other departments to achieve solid-liquid separation, Mixture dehydration, slurry concentration and other functions. Due to the large structure of the heavy-duty pressure centrifuge and its operation in a pressurized closed production line, the operational reliability of each component and the whole machine is very high. After investigating the operating conditions and failure causes of the centrifuges in the PTA units of Sinopec and PetroChina, it was found that the failures of the ...
