    \n
  1. V\u00e9rifier la direction du moteur ; remplacer la pompe ou la cl\u00e9 ; nettoyer et r\u00e9parer la soupape de d\u00e9charge ; remplacer le ressort ; nettoyer, r\u00e9parer ou remplacer ; v\u00e9rifier l'\u00e9tat des pi\u00e8ces d'usure de la pompe, du cylindre et de la soupape et l'\u00e9tanch\u00e9it\u00e9 de chaque raccord dans le syst\u00e8me.<\/li>\n\n\n\n
  2. Le d\u00e9bit de la pompe variable est mal r\u00e9gl\u00e9 - le r\u00e9gler au d\u00e9bit requis. La pression de la pompe \u00e0 huile (pompe hydraulique) ne peut pas augmenter. La pompe \u00e0 huile n'est pas huil\u00e9e ou le d\u00e9bit est insuffisant - M\u00eame m\u00e9thode de d\u00e9pannage que ci-dessus. La pression de r\u00e9glage de la soupape de d\u00e9charge est trop basse ou fonctionne mal - R\u00e9ajuster la pression de la soupape de d\u00e9charge ou r\u00e9parer la soupape de d\u00e9charge.<\/li>\n\n\n\n
  3. Cause de la d\u00e9faillance : L'huile hydraulique est trop sale. M\u00e9thode de d\u00e9pannage : Nettoyez le syst\u00e8me et remplacez l'huile hydraulique.<\/li>\n\n\n\n
  4. Quant \u00e0 l'entretien de la pompe \u00e0 huile hydraulique, il n'est pas difficile. Voici une m\u00e9thode simple et pratique : le pon\u00e7age grossier. Placez la toile \u00e9meri grossi\u00e8re 120# sur le verre plat, ajoutez un peu d'huile moteur et du sable abrasif 80 mesh, puis placez la plaque de distribution d'huile \u00e0 plat sur la toile \u00e9meri pour un meulage lisse. La technique de meulage \u00e0 plat est la suivante : meulage en tournant, la trajectoire est en forme de \"8\".<\/li>\n\n\n\n
  5. M\u00e9thode d'entretien de la pompe hydraulique Forme d'alimentation en huile de la pompe hydraulique - la pompe \u00e0 piston \u00e0 axe droit poss\u00e8de deux formes d'alimentation en huile, \u00e0 savoir l'alimentation en huile sous pression et l'huile auto-amor\u00e7ante. Les pompes hydrauliques \u00e0 alimentation sous pression utilisent g\u00e9n\u00e9ralement un r\u00e9servoir de gaz sous pression d'air. Certaines pompes hydrauliques sont elles-m\u00eames dot\u00e9es d'une sous-pompe d'alimentation en huile qui fournit de l'huile sous pression \u00e0 l'entr\u00e9e d'huile de la pompe hydraulique.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":6457,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"#ffffff","themepark_post_main_p":100,"themepark_paddingblock":false,"footnotes":""},"categories":[7],"tags":[],"class_list":["post-5149","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"metadata":{"catce":["sidebar-widgets4"],"views":["2591"],"hot_img":["http:\/\/data.themepark.com.cn\/2020\/n\/thousandfaceIHorizon_data\/qy1\/uploads\/2019\/04\/big_news1.png"],"themepark_post_img":[""],"themepark_post_img_re":[""],"themepark_post_img_cover":[""],"themepark_post_img_fixed":[""],"themepark_post_hide_title":[""],"themepark_post_main_b":["#ffffff"],"themepark_paddingblock":[""],"_wxr_import_has_attachment_refs":["1"],"_wp_old_slug":["wordpress%e7%bd%91%e7%ab%99%e6%9c%89%e4%bb%80%e4%b9%88%e6%a0%b7%e7%9a%84%e4%bc%98%e5%8a%bf-3","repair-and-maintenance-of-hydraulic-system-machinery-4"],"_dp_original":["5147"],"_edit_lock":["1722583244:1"],"_edit_last":["1"],"themepark_seo_description":["Check the motor steering; replace the pump or key; clean and repair the relief valve; replace the spring; clean, repair or replace; check the condition of wearing parts in the pump, cylinder, and valve and the sealing of each connection in the system."],"_thumbnail_id":["6457"],"wp_statistics_words_count":["256"],"_trp_automatically_translated_slug_fr_FR":["quelles-sont-les-methodes-de-reparation-en-cas-de-defaillance-dune-pompe-hydraulique"],"_trp_automatically_translated_slug_es_ES":["cuales-son-los-metodos-de-reparacion-en-caso-de-averia-de-una-bomba-hidraulica"],"_trp_automatically_translated_slug_ru_RU":["\u043a\u0430\u043a\u043e\u0432\u044b-\u043c\u0435\u0442\u043e\u0434\u044b-\u0440\u0435\u043c\u043e\u043d\u0442\u0430-\u043d\u0435\u0438\u0441\u043f\u0440\u0430\u0432\u043d\u043e\u0441\u0442\u0438"]},"medium_url":"https:\/\/www.rchchydraulics.com\/wp-content\/uploads\/2024\/07\/RCZY-series-heavy-cast-iron-single-pumpew-1-300x168.jpg","thumbnail_url":"https:\/\/www.rchchydraulics.com\/wp-content\/uploads\/2024\/07\/RCZY-series-heavy-cast-iron-single-pumpew-1-150x150.jpg","full_url":"https:\/\/www.rchchydraulics.com\/wp-content\/uploads\/2024\/07\/RCZY-series-heavy-cast-iron-single-pumpew-1.jpg","_links":{"self":[{"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/posts\/5149","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/comments?post=5149"}],"version-history":[{"count":3,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/posts\/5149\/revisions"}],"predecessor-version":[{"id":5842,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/posts\/5149\/revisions\/5842"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/media\/6457"}],"wp:attachment":[{"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/media?parent=5149"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/categories?post=5149"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.rchchydraulics.com\/fr\/wp-json\/wp\/v2\/tags?post=5149"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
