Embodiment Construction

[0027] The present invention will be further explained below in conjunction with the description of the drawings and specific embodiments:

[0028] See Figure 3 to Figure 5 , A mechanical seal online monitoring system, based on a mechanical seal device, including a data processing unit, a detection unit connected to the data processing unit, and a user terminal, the detection unit including an I / O module and a motor speed connected to the I / O module Sensors, current sensors, radial vibration sensors 13 and noise sensors, of which:

[0029] The data processing unit is used to process data from the detection unit and the user terminal;

[0030] The detection unit is used to detect the working state of the mechanical seal device and feed back sensor signals to the data processing unit;

[0031] The user terminal is used to exchange data with the data processing unit and display the monitoring results.

[0032] The motor speed sensor is arranged on the motor shaft 7 and is used to detect ...

Abstract

The invention relates to a mechanical seal online monitoring system which comprises a data processing unit, a detection unit and a user terminal, wherein the detection unit is connected with the data processing unit; and the detection unit comprises an I / O (Input / Output) module, and a motor rotating speed sensor, a current sensor, a radial vibration sensor and a noise sensor which are connected with the I / O module. In the system, acquired data is subjected to the multivariable statistics process monitoring by the data processing unit, so that the indirect monitoring for the mechanical seal operation condition is realized and an early warning signal can be given in the fault early phase of the mechanical seal, and thus, a production accident is avoided, the loss of raw materials, equipment and other aspects of an enterprise is reduced and the possibility is provided for detection of the mechanical seal state and failure prediction. Meanwhile, the equipment is checked by the monitoring system without shutting down, so that compared with the prior art, a great amount of time and human resources are saved and the production efficiency of the enterprise is improved.

Description

Technical field [0001] The invention belongs to the field of process monitoring and fault diagnosis, and more specifically, relates to an online monitoring system for mechanical seals. Background technique [0002] Mechanical seal is an oil seal device widely used in rotating machinery, such as centrifugal pumps, centrifuges, reactors, compressors and other equipment. It relies on one or several pairs of end faces perpendicular to the shaft for relative sliding in the fluid pressure and compensation mechanism Under the action of elastic force (or magnetic force), it can be kept attached and matched with auxiliary sealing to achieve the effect of preventing leakage. See figure 1 , The main components of the mechanical seal are the moving ring 8 and the static ring 9. The spring seat 1 behind the moving ring 8 is fixed on the shaft or sleeve 7 by the fastening screw 2, and moves synchronously with the shaft or sleeve 7. , The static ring 9 is fixed on the gland by the anti-rotatio...
