ʻO ka hoʻokaʻawale hoʻokaʻawale ʻana i ka pauma centrifugal multistage (API610/BB3)

1. Shell: axially split a kākoʻo kokoke i ke kikowaena laina. Hoʻonohonoho ʻia nā flanges inlet a me nā puka puka ma ke kino pamu. Hiki ke hoʻomaopopo maʻalahi i ka nānā ʻana a me ka mālama ʻana i ka paila me ka ʻole o ka neʻe ʻana i nā pipeline inlet a me waho, a ua maʻalahi ke kaulike rotor a me ka nānā ʻana. a me ka hoʻokomo ʻana, ka nānā ʻana a me ka hoʻololi ʻana i nā kahawai kahe o ke kino pump, a me ka hoʻololi ʻana i nā ʻāpana ʻāpana rotors.

2. Impeller: ka hoʻolei pololei ʻana, ke kaupaona ʻana a me ka hoʻoponopono ʻana o kēlā me kēia impeller. ʻO ka impeller he mea hoʻopilikia kūpono, a ʻo kēlā me kēia pae impeller e hoʻohana i kahi hoʻolālā stepped shaft no ka maʻalahi o ka hoʻonohonoho ʻana a me ka mālama ʻana; Hiki ke ho'olako 'ia ka DN80 (outlet) a me nā kiko'ī i luna me ka Impeller suction pālua mua no ka ho'omaika'i 'ana i ka pale cavitation NPSH.

3. Ka ikaika axial a me ke koena o ka ikaika radial: Ua hoʻonohonoho ʻia nā impellers i hope-a-hope symmetrically e hoʻohālikelike pono i ka ikaika axial. ʻO ka puʻu waena a me ka puʻu puʻu e kaulike i ke koena axial ikaika. He haʻahaʻa wale nō ka haʻahaʻa o ka pahu kuʻi; like ka volute i luna a i lalo. Hoʻonohonoho i hoʻolālā ʻia no nā ikaika radial liʻiliʻi e loaʻa i nā deformations kumu liʻiliʻi a me nā haʻahaʻa.

4. Nā bearings a me ka lubrication: Hoʻohana nā bearings i ka ʻaila ring self-lubricating structure bearings a i ʻole ka hoʻoikaika ʻana i ka lubrication structure bearings e like me ka mana a me ka wikiwiki. Hoʻohana ka moʻo holoʻokoʻa i nā sila ʻano isolator a me nā pahu lawe kila kalapona. Hiki ke hoʻomaʻamaʻa ʻia nā pahu halihali a i ʻole ka wai. Loaʻa ka hoʻoluʻu.

5. Shaft seal: Ke hoʻokō nei ka ʻōnaehana sealing i ka 4th edition o API682 "Centrifugal Pump and Rotary Pump Sealing System" a hiki ke hoʻonohonoho ʻia me nā ʻano like ʻole o ka sealing, flushing, a me nā hoʻonā hau.
