Vaevae pusa double suction pumps and single suction pumps are two common types of centrifugal pumps, each with a unique structural design and working principle. Double suction pumps, with their double-sided suction characteristics, can achieve a larger flow rate under the same impeller outer diameter, attracting the attention of many industries. 

This article will explore the main differences between the two pump types, as well as the advantages of double suction pumps in flow and efficiency, to help readers better understand how to choose the most suitable pump type in different application environments.

E tele eseesega taua i le va pamu miti fa'alua ma pamu fa'asusu tasi:

Single suction pump:There is only one suction port, and the fluid enters the impeller from one direction.

Double suction pump:There are two suction ports, and the fluid enters the impeller from two directions, usually a symmetrical design.

Gafatia gafatia

Faatasi ai ma le tutusa impeller pito i fafo, o le tafe o le pusa vaelua pamu suction lua e mafai moni lava faaluaina o le pamu suction tasi. E mafua ona o le pamu suction lua e mafai ona mitiia le vai mai itu e lua i le taimi e tasi, o lea e mafai ai ona gaosia se fua faatatau tafe i le saoasaoa tutusa ma le mamanu impeller tutusa.

talosaga:

O pamu fa'asusu ta'itasi e talafeagai mo taimi e la'ititi le mana'omia o le tafe ma le mamanu faigofie; a'o pamu suction lua e sili atu ona talafeagai mo taimi e manaʻomia le tafe maualuga, aemaise lava pe a manaʻomia le faʻaleleia lelei ma e manaʻomia le faʻaitiitia o le vibration.

Lelei ma mautu:

O pamu fa'alua fa'alua e masani ona sili atu le paleni ma fa'aitiitia le vibrate i le taimi o le fa'agaioiga, lea e sili atu ona talafeagai i nisi o fa'aoga maualuga.

Faigaluega

O le mataupu faavae galue o pamu suction lua e masani ona faavae i luga o mataupu faavae o le malosi centrifugal ma tafe vai. O lo'o taua i lalo se fa'amatalaga lautele o le fa'agasologa o galuega o pamu fa'asusu fa'alua:

Fausaga foliga:

O pamu fa'alua fa'alua e masani lava ona aofia ai se fa'aoso fa'atotonugalemu fa'atasi ai ma se fa'amomoli i itu ta'itasi. O le impeller ua mamanuina ina ia mafai e le vai ona ulufale mai i itu e lua, e fai ai se suction tutusa.

Suavai ulufale:

A amata le pamu fa'alua fa'asusu, e fa'aosoina e le afi le impeller e fa'asolo. O le vai e ulu atu i le ogatotonu o le impeller e ala i le lua suction ports. O lenei fausaga e mafai ona faʻaitiitia lelei le le paleni o le tafe o le vai.

Le aafiaga o le malosi centrifugal:

A o feliuliua'i le impeller, e faatelevaveina le vai ma agai i fafo i lalo o le gaioiga o le malosi centrifugal. E maua e le vai le malosi i totonu o le impeller ma faasolosolo malie le saoasaoa.

La'u sua:

A maeʻa ona ui atu le vai i totonu o le impeller, e faʻatuputeleina le tafe o le tafe ma faʻasalalau i totonu o le pusa pamu (vaivai). E masani lava ona tu i le pito i luga poʻo le itu o le pamu.

Si'itia Osi:

I lalo o le gaioiga o le centrifugal force, o le mamafa o le suavai e faʻateleina foi ma le faʻateleina o le tafe, faʻatagaina le pamu faʻalua faʻafefe e feaveaʻi le vai i totonu o le pamu i se nofoaga mamao poʻo se maualuga maualuga.

talosaga

Ona o lona fausaga tulaga ese ma le lelei o le faatinoga, o le vaeluaga tulaga lua suction pamu e talafeagai mo le tele o alamanuia ma nuu talosaga siosiomaga. O nisi nei o vaega autu o talosaga:

Suavai a le Malo:

Fa'aaogaina mo le tu'uina atu ma le tufatufaina o vai paipa i le taulaga e fa'amalieina mana'oga o vai nofomau, pisinisi ma fale gaosi oloa.

Togafitiga Suavai:

Fa'aaoga tele i fale fa'asusu vai, aemaise i le fa'agasologa o le pamuina o le vai mata ma togafitiga, e fesoasoani i le felauaiga o lapisi ma suavai leaga.

Fiafia Faigaluega:

I totonu o le faʻafefeteina o le faʻaogaina o le eletise, vailaʻau vailaʻau ma isi fale gaosi oloa, e mafai e pamu suction lua ona felauaiga lelei le vai malulu.

Fa'avai ma Fa'ato'aga:

Fa'aaogaina i faiga fa'ato'aga e fesoasoani i le felauaiga lelei o le vai i fanua fa'ato'aga ma fa'aleleia atili ai le fa'asusuina.

Faiga Tinei Mu:

Faʻaaogaina i le afi afi o fale tetele poʻo nofoaga faʻapisinisi, tuʻuina atu se vai mautu ma faʻatuatuaina e faʻamautinoa ai le saogalemu.

Alamanuia vaila'au:

Fa'aoga mo le felauaiga o vaila'au po'o mea fa'asuavaia, ma fa'agasologa e maualuga le tafe ma mana'oga mamafa.

Eliina ma Eliina:

Fa'aoga mo alavai ma le sapalai o vai i maina, fesoasoani e pulea le maualuga o le vai ma fa'aleleia le saogalemu o galuega.

Faiga Fa'alelei:

I faiga fa'alelei tele, fa'aaogaina e fa'afefe ai le vai malulu po'o le malulu e fa'amautinoa ai le fa'aogaina lelei o meafaigaluega.
