La planta de ox\u00edgeno VPSA<\/u><\/strong><\/a> deben presentar las siguientes caracter\u00edsticas:<\/p>\n1. alta velocidad de conmutaci\u00f3n<\/p>\n
2. buen rendimiento de sellado<\/p>\n
3. larga vida \u00fatil bajo condiciones de conmutaci\u00f3n frecuente y r\u00e1pida<\/p>\n
4. Funcionamiento sin aceite<\/p>\n
Actualmente, las plantas VPSA nacionales generalmente adoptan v\u00e1lvulas de mariposa neum\u00e1ticas especiales de doble exc\u00e9ntrica cuyos actuadores y componentes neum\u00e1ticos son fabricados por marcas reconocidas como Metso y SMC para mejorar la confiabilidad de las v\u00e1lvulas. La v\u00e1lvula tiene las siguientes caracter\u00edsticas:<\/p>\n
1. Amplio rango de calibre: di\u00e1metro de DN100 a DN900<\/p>\n
2. Alta velocidad de conmutaci\u00f3n: 0.3 a 0.8 segundos\/vez<\/p>\n
3. Estructura de sellado: estructura de sellado de labio con fuga cero bidireccional y autorreparaci\u00f3n tras el desgaste<\/p>\n
4. Materiales de sellado: material de PTFE reforzado con alta resistencia al desgaste<\/p>\n
5. Accionamiento: accionado por gas de instrumento de baja presi\u00f3n, limpio y sin aceite, que es relativamente f\u00e1cil de obtener.<\/p>\n
6. Mantenimiento: La v\u00e1lvula es de tama\u00f1o peque\u00f1o, peso ligero y f\u00e1cil de mantener. El costo de mantenimiento es inferior al de otros tipos de v\u00e1lvulas.<\/p>","protected":false},"excerpt":{"rendered":"
El ciclo de operaci\u00f3n del proceso de producci\u00f3n de ox\u00edgeno VPSA es muy corto, generalmente menos de 1 minuto. En un ciclo, cada recipiente de adsorci\u00f3n debe experimentar los pasos de adsorci\u00f3n, reducci\u00f3n de presi\u00f3n, desorci\u00f3n, purga, incluso aumento de presi\u00f3n, etc. Las v\u00e1lvulas clave se encienden y apagan una vez en cada ciclo, lo cual es bastante frecuente, por lo que son…<\/p>","protected":false},"author":1,"featured_media":1895,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_gspb_post_css":"","_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-3169","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"acf":{"en-title":"","en-meta":"","en-content":"","es-title":"","es-meta":"","es-content":"","ru-title":"","ru-meta":"","ru-content":"","pt-title":"","pt-meta":"","pt-content":"","de-title":"","de-meta":"","de-content":"","th-title":"","th-meta":"","th-content":"","ja-title":"","ja-meta":"","ja-content":"","ko-title":"","ko-meta":"","ko-content":"","fr-title":"","fr-meta":"","fr-content":"","ar-title":"","ar-meta":"","ar-content":"","id-title":"","id-meta":"","id-content":""},"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}]},"featured_image_src_large":["https:\/\/vpsatech.com\/wp-content\/uploads\/2026\/04\/5e0aa088efdf1.jpg",580,466,false],"author_info":{"display_name":"yiyunyingalex","author_link":"https:\/\/vpsatech.com\/es\/author\/yiyunyingalex"},"comment_info":0,"category_info":[{"term_id":1,"name":"Uncategorized","slug":"uncategorized","term_group":0,"term_taxonomy_id":1,"taxonomy":"category","description":"","parent":0,"count":194,"filter":"raw","cat_ID":1,"category_count":194,"category_description":"","cat_name":"Uncategorized","category_nicename":"uncategorized","category_parent":0}],"tag_info":false,"_links":{"self":[{"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/posts\/3169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/comments?post=3169"}],"version-history":[{"count":2,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/posts\/3169\/revisions"}],"predecessor-version":[{"id":3527,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/posts\/3169\/revisions\/3527"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/media\/1895"}],"wp:attachment":[{"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/media?parent=3169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/categories?post=3169"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vpsatech.com\/es\/wp-json\/wp\/v2\/tags?post=3169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
