Problems solved by technology

[0003] At present, most of the seal adjustments are self-sealing static adjustments, which cannot meet the dynamic adjustment when the working conditions change; on the other hand, the mechanical seal control device adopts fuzzy control algorithm, which is sensitive and can meet the intelligent control requirements of variable working conditions.

Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0016] reference figure 1 , A new type of mechanical seal control device disclosed in the present invention includes: a software module, a control module and a mechanical module. Among them, the software module is the mfkzV1.0 system; the control module includes a PCI6221 board, terminal junction box and stepper motor; the mechanical module includes a sealing device and a base.

[0017] The working process of the present invention is as follows: the mechanical seal component changes with the change of the working conditions, the leakage amount changes, and the leakage amount change information will be collected, converted into electrical signals, and transmitted to the system through the PCI6221 board, and the software system is fuzzy through query The fuzzy control table generated b...

Abstract

The invention discloses a novel mechanical seal control device, to realize fast response of seal adjustment under changing working conditions. The device is an effective sealing control device for thetransportation of toxic, harmful and dangerous chemicals, and can reduce the leakage possibility of toxic, harmful and dangerous chemicals. The seal real-time control is enhanced. The leakage response speed is improved. The seal safety and the control instantaneity are both taken into account. According to the technical scheme of the invention, the device has the advantages of advanced design, complete functions, real-time control, safety and convenient maintenance, meets the multiple demands of mechanical seal control, meets the control requirement of modern intelligent sealing, and can serve many companies with high sealing performance requirements.

Description

Technical field [0001] The invention relates to the field of mechanical seals, in particular to a new type of seal control device. Background technique [0002] Mechanical seal technology is widely used in important technical fields of the national economy. The most important indicators to measure the performance of mechanical seals are leakage rate and service life. Under the premise of guaranteeing the service life, it is necessary to ensure that the leakage change can be quickly tracked and adjusted as the working conditions change. The hardware of this set of sealing leakage control and adjustment device uses NI's PCI6221 acquisition card, and the software platform uses LabVIEW. A fuzzy controller is designed based on the fuzzy control algorithm, and the stepping drive system is driven by the PCI 6221 card to adjust the spring pressure of the drive seal cavity to change the seal, so as to achieve a good sealing effect under variable conditions. [0003] At present, most of th...
