Chemical automation instrument installation engineering construction characteristics and the concrete method

Abstract: the chemical industrial automation instrument installation project construction characteristics and methods of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In this paper: chemical automation instrument is zui basic equipment in the chemical production, and ensure that chemical production automation for guarantee, for instrument installation project is a process of systematization, specialization is very strong, the lack of professional operation, will be. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the chemical industrial automation instrument installation project construction characteristics and the concrete method of the article details. In this paper: chemical automation instrument is zui basic equipment in the chemical production, and ensure that ensure that chemical production automation, for instrument installation project is a process of systematization, specialization is very strong, the lack of professional operation, will cause hidden trouble to the future production run, seriously affect the efficiency and effectiveness of production, and even cause harm to the personal safety of operators, this must be addressed at the initial planning enterprise project. The rapid development of modern petrochemical industry, the production equipment large scale, highly automated, intelligent, informatization has become an inevitable trend, and form a complete set of automation instrument usage is becoming more and more big, the great consumption of such as the production of electromagnetic flowmeter, ultrasonic flowmeter, such as the flow measurement device, has fully realized the intelligent and high degree of automation. In order to ensure the production device can smooth and safe operation, high yield and long cycle of automation instrument installation work also put forward higher requirements. Article the paper discusses the characteristics of chemical industry automation instrument installation, follow the principle, instrument installation of several stages, as well as the work of each stage and the concrete construction method. Combined with the author's work in the automation instrument installation management practice practice, looking for your installation work. A, the characteristics of automation instrument installation and follow the principle of ( 1) Automation instrument installation points, more wide surface, large volume, high technical requirements, installation of cross homework more, late time focused on the main installation engineering; （ 2) Automation instrument for process service this feature determines its and process equipment, process piping, civil, electrical, insulation and non-standard production and so on various professional, must maintain close cooperation and collaboration. The installation process, automatic control professional often require active, even for the tail from wagging the dog to make local concessions, can finish the installation tasks zui end; （ 3) Automation instrument installation project construction principle is: civil engineering after the first installation, after the first underground floor, on both ends of the first installation of equipment and piping layout, first ( Control room, turf, field and on-site instrument) After the middle ( Cable trough, junction box, protection tube, cable, electrical, and instrument piping, etc. ) 。 Instrument equipment installation should follow the principle is: after the first, the first after the high low, heavy light after first. Instrument calibration should follow the principle is: first, after checking, inter-school after single school first, first single loop again complex circuit, after the first single point network; （ 4) Instrument installation general requirements: first, emphasis is reasonable, and then the beautiful, avoid by all means air with water, transverse uneven, vertical, straight to clean and lively, clean and neat. Second, automation instrument automation instrument installation generally can be divided into three stages, namely the construction preparation stage, construction stage, commissioning completion stage. 3. 1 construction preparation stage construction preparation is an important stage in instrumentation installation, it works fully or not, a direct impact on the completion of tasks of construction progress and the whole construction. Construction preparation stage of the specific work includes: 3. 1. 1 material preparation. Data preparation including construction drawing, control instrument installation of atlas, the automation instrument engineering construction and acceptance standard 'GB50093 - 2002, the automation instrument engineering construction quality acceptance specification 'GB50131 - 2007, the petroleum chemical instrumentation engineering construction technical regulation SH/T3521 - 2007, as well as other related technical documents, etc. Construction is a unit during the installation process, zui zui important direct technical documents, only understand design intent, make clear design concept, understand the characteristics and difficulties of installation works, focus, and the overall amount of engineering tasks, etc. , can accomplish know fairly well, to go to overall consideration, construction organization also can in an orderly way, a reasonable and orderly. Acceptance standard of construction is the construction of must achieve and comply with technical requirements and process discipline. Construction technical management personnel should be familiar with construction drawing and the corresponding national acceptance specifications, industry standards, and organize the construction personnel learning seriously. Data preparation also includes all kinds of inspection list and record form, construction form and quality record forms, etc. 3. 1. 2 technical preparation. Technical preparation is done on the basis of the data preparation, specific have the following preparation work: ( 1) The preparation of construction organization design and construction scheme. Construction plan of zui is the main part of the construction method and construction process, this part to write specific, detailed, construction personnel in accordance with the plan can according to the steps of the construction. Construction quality requirements and quality assurance measures is the basis of the construction plan, only on the premise of guarantee the quality of the construction about construction progress.
