SOF/SOU High suction pressure pump (API610/OH2)

Pampu ya OH2 yotsatizana ndi petrochemical process ndi yopingasa, siteji imodzi, mpope wogawanika wa cantilever centrifugal. Mapampu amtundu uwu ali ndi bokosi lonyamula lapadera kuti anyamule mphamvu zonse zomwe zimagwiritsidwa ntchito pa shaft ya mpope ndikuwonetsetsa malo a rotor. Pampu imayikidwa Patsinde ndipo imalumikizidwa ndi dalaivala wake ndi cholumikizira chosinthika.

1. Pampu thupi: Thupi la mpope limagwiritsa ntchito kapangidwe ka volute. Pampu body outout ≥DN80 imagwiritsa ntchito mawonekedwe a hydraulic owirikiza kawiri, omwe amalinganiza mphamvu ya radial mpaka pamlingo waukulu. Kukula kwa flange orifice kudapangidwa molingana ndi zofunikira za API610. Thupi la mpope Thandizo lapakati limatha kupititsa patsogolo kukhazikika kwamafuta ndikupirira kuchuluka kwa nozzle. The ngalande mawonekedwe a mpope thupi ndi welded ndi integrally flanged;

2. Zigawo zonyamula: Zigawo zonyamula (bokosi lonyamula, kunyamula, shaft, gland, chivundikiro cha pampu, ndi zina zotero) zimagwiritsa ntchito mapangidwe onse otulutsa, omwe amathandiza kuyang'anitsitsa ndi kukonza pampu popanda kusuntha mapaipi olowera ndi kutuluka. Zigawo zonyamula zimagwiritsa ntchito mapangidwe okhwima, ndipo palibe chiboliboli chonyamula kumapeto kwa bokosi lonyamula;

3. Shaft: Mtsinjewo ndi mawonekedwe a shaft opanda kanthu, ndipo ndondomeko yolimba ya shaft ya pampu imakwaniritsa zofunikira za API61011 Appendix K. Panthawi imodzimodziyo, ndondomeko ya anti-reverse nut imatengedwa kuti ikwaniritse zosowa za malo. malo ogwira ntchito ndikuwongolera chitetezo ndi kukhazikika kwa zida.

4. Axial mphamvu yolinganiza: Mphete zosamva kuvala zimapangidwira mbali zonse za choyimitsa, ndipo dzenje loyang'anira limatsegulidwa mkati kuti lipangitse kupanikizika kumbali zonse za chiwongoladzanja chodziletsa, ndipo kukwera kwake kumangokhalira kutsika. katundu.

5. Ma bearings ndi mafuta odzola: Kumbali yakutsogolo (kuyandikira pafupi ndi mutu wa mpope) kumagwiritsa ntchito mayendedwe ozama a mpira, omwe amangokhala ndi mphamvu yozungulira. Kumbuyo kwake (chokhala pafupi ndi mapeto oyendetsa) chimagwiritsa ntchito mipiringidzo yolumikizana ndi angular (73 series) kapena zitsulo zodzigudubuza (31 series); mayendedwe amatengera mawonekedwe a mphete yamafuta, ndipo chosindikizira chamtundu wa isolator chimatha kusankhidwa malinga ndi zosowa za ogwiritsa ntchito Kapena chisindikizo cha labyrinth.

6. Makina osindikizira: Kukula kwa mtsempha wotsekera kumayenderana ndi API682 4th "Shaft Seal System for Centrifugal Pump and Rotary Pump", ndi njira zosiyanasiyana zosindikizira, zotsekemera, ndi zoziziritsa zingathe kukhazikitsidwa.
