Problems solved by technology

How to control equipment leakage, we conduct serious research: all process control equipment in the petrochemical industry is connected by flanges, the reliability of flange connections is mainly determined by the reliability of bolt fastening, while the domestic petrochemical industry mainly depends on the bolt fastening It is carried out by manual knocking, without scientific calculation of the fastening force and scientific analysis of the fastening process, the size and uniformity of the force are greatly limited, and the site cannot be monitored, and all equipment is in an uncontrollable safety performance. state, these will inevitably bury certain security risks

Embodiment Construction

[0010] The bolt fastening system and method of the present invention will be described in detail below with reference to the accompanying drawings.

[0011] The fastening system of the present invention mainly includes four components: a data parameter acquisition module, a bolt fastening load calculation and analysis module, a bolt fastening execution module, and a data online detection and reliability analysis module.

[0012] 1. Data parameter acquisition module

[0013] The data acquisition module is mainly used to collect data parameters and establish a corresponding data parameter database. The data parameters to be collected include: (1) user name, site location, equipment name, equipment number, flange name, flange number, bolt number ;(2) The specific form of the flange, such as: standard, grade, size; (3) The specific form of the seal, such as: gasket seal, seal material type, seal specific pressure, seal size; (4) Pipeline grade and size ; (5) The material grade an...

Abstract

The invention provides a bolt fastening system which belongs to the safety control field of bolt flanges of petroleum and petrifaction devices. The bolt fastening device comprises a data parameter acquisition module, a computation analysis module of bolt fastening loads, a bolt fastening execution module and a data on-line detection and reliability analysis module. The computation analysis moduleof bolt fastening loads computes and analyzes load data required by fastening a bolt according to data parameters in a database and transmits the computed load data to the bolt fastening execution module; and the bolt fastening execution module automatically selects a used fastening mode according to the computed load data, thereby guiding the fastening execution operation. The bolt fastening system has convenient and reliable operation, accurately controls the bolt fastening operation, can reflect the stress condition of the bolt in real time and alarm when exceeding the safety guard, therebyradically controlling the safety of flanges.

Description

technical field [0001] The invention relates to the field of safety control of bolt flanges of petroleum and petrochemical devices, in particular to a bolt fastening system in petroleum and petrochemical devices. Background technique [0002] Oil and petrochemical accidents occur frequently around the world every year, causing immeasurable losses. The authoritative department analyzed the accidents and concluded that 80% of them were caused by the leakage of these devices. How to control equipment leakage, we conduct serious research: all process control equipment in the petrochemical industry is connected by flanges, the reliability of flange connections is mainly determined by the reliability of bolt fastening, while the domestic petrochemical industry mainly depends on the bolt fastening It is carried out by manual knocking, without scientific calculation of the fastening force and scientific analysis of the fastening process, the size and uniformity of the force are gre...
