Gawani mlandu 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.

Pali kusiyana kwakukulu pakati mapampu awiri oyamwa ndi mapampu amodzi okha:

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.

Mphamvu zoyenda

Ndi chiwongolero chakunja chomwecho, kuthamanga kwa mpope wogawanika pawiri woyamwa ukhoza kuwirikiza kawiri pampopi imodzi yoyamwa. Izi ndichifukwa choti pampu yoyamwa pawiri imatha kuyamwa madzi kuchokera mbali ziwiri nthawi imodzi, kotero imatha kutulutsa kuthamanga kokulirapo pa liwiro lomwelo komanso kapangidwe kake kofananako.

ntchito:

Pampu zoyamwitsa zing'onozing'ono ndizoyenera nthawi zina zomwe zimakhala ndi zofunikira zochepa komanso zosavuta kupanga; pomwe mapampu okokera pawiri ndi oyenera nthawi zina zomwe zimafunikira kuyenda kwakukulu, makamaka pamene mphamvu ikufunika kuwongolera komanso kugwedezeka kuyenera kuchepetsedwa.

Kuchita bwino ndi kukhazikika:

Mapampu oyamwa kawiri amakhala okhazikika komanso amanjenjemera pang'ono panthawi yogwira ntchito, zomwe zimawapangitsa kukhala oyenera pamapulogalamu ena othamanga kwambiri.

Ntchito yopita

Mfundo yogwirira ntchito ya mapampu akuyamwa pawiri imachokera pa mfundo zazikulu za mphamvu ya centrifugal ndi kutuluka kwamadzimadzi. Zotsatirazi ndizomwe zimagwira ntchito papampu zoyamwa kawiri:

Zomangamanga:

Pampu zoyamwa kawiri nthawi zambiri zimakhala ndi choyikapo chapakati chokhala ndi doko loyamwa mbali iliyonse. Choyikacho chimapangidwa kuti madziwo alowe kuchokera mbali ziwiri, kupanga symmetrical suction.

Kulowa kwamadzi:

Pampu yoyamwa pawiri ikayambika, mota imayendetsa choyikapo kuti chizungulire. Madzimadzi amalowa pakati pa choyikapocho kudzera m'madoko awiri oyamwa. Kapangidwe kameneka kamatha kuchepetsa kusagwirizana kwa madzi otaya.

Mphamvu ya centrifugal:

Pamene choyikapo chimayenda, madziwo amathamanga ndipo amapita kunja pansi pa mphamvu ya centrifugal. The madzi amapeza mphamvu mu impeller ndi liwiro pang'onopang'ono ukuwonjezeka.

Kutuluka kwamadzi:

Madziwo akadutsa pa choyikapocho, kuthamanga kwa magazi kumawonjezeka ndipo kumatulutsidwa kudzera pampopi yamadzi (madzi). Chotulukira nthawi zambiri chimakhala pamwamba kapena mbali ya mpope.

Pressure Boost:

Pansi pa mphamvu ya centrifugal, kuthamanga kwa madzimadzi kumawonjezekanso ndi kuwonjezeka kwa kuthamanga kwa magazi, kulola kuti pampu yoyamwa iwiri itengere madzi mu mpope kupita kumalo akutali kapena kumtunda.

Mapulogalamu

Chifukwa cha mawonekedwe ake apadera komanso magwiridwe antchito abwino, pampu yogawanitsa kawiri ndi yoyenera m'malo osiyanasiyana ogwiritsira ntchito mafakitale ndi matauni. Nawa ena mwa madera akuluakulu ofunsira:

Madzi a Municipal Water:

Amagwiritsidwa ntchito popereka ndi kugawa madzi apampopi akumidzi kuti akwaniritse zosowa zamadzi okhala, malonda ndi mafakitale.

Kuyeretsa Madzi ku Industrial Water:

Amagwiritsidwa ntchito kwambiri m'mafakitale opangira madzi, makamaka popopera madzi osaphika ndi kuchiritsa, kuthandiza kunyamula zimbudzi ndi madzi otayira.

Njira Yozizira:

Mu njira yozizira yozungulira yamagetsi, zopangira mankhwala ndi zida zina zamafakitale, mapampu akuyamwa kawiri amatha kunyamula madzi ozizira bwino.

Kuthirira ndi ulimi:

Amagwiritsidwa ntchito mu ulimi wothirira njira zothandizira kunyamula madzi kupita kumunda komanso kukonza ulimi wothirira bwino.

Njira Yozimitsa Moto:

Kugwiritsidwa ntchito ku dongosolo lozimitsa moto la nyumba zazikulu kapena malo ogulitsa mafakitale, kupereka madzi okhazikika komanso odalirika kuti atsimikizire chitetezo.

Makampani a Chemical:

Amagwiritsidwa ntchito popereka mankhwala kapena zinthu zamadzimadzi, komanso njira zomwe zimatuluka komanso kuthamanga kwambiri.

Migodi ndi miyala:

Amagwiritsidwa ntchito ngati ngalande ndi kupereka madzi m'migodi, kuthandiza kuwongolera kuchuluka kwa madzi ndikuwongolera chitetezo chantchito.

Ma Air Conditioning System:

M'makina akuluakulu oziziritsa mpweya, amagwiritsidwa ntchito kusamutsa madzi ozizira kapena ozizira kuti zitsimikizire kuti zida zikugwira ntchito bwino.
