Menene Shugaban Pump?

Shugaban famfo, wanda galibi ake magana da shi a matsayin jimlar kai ko jimlar kai mai ƙarfi (TDH), yana wakiltar jimillar makamashin da ake ba ruwa ta famfo. Yana ƙididdige haɗin ƙarfin matsi da makamashin motsa jiki wanda famfo ke bayarwa ga ruwa yayin da yake tafiya cikin tsarin.A takaice, muna iya ayyana kai a matsayin matsakaicin tsayin ɗagawa wanda famfo ke iya watsawa zuwa ruwan da aka buɗa. Mafi bayyanan misalin shi ne na bututun tsaye yana tashi kai tsaye daga mashigar isarwa. Za a zubar da ruwa a cikin bututu mai nisan mita 5 daga wurin fitarwa ta hanyar famfo mai kan mita 5. Shugaban famfo yana da alaƙa da jujjuyawar magudanar ruwa. Mafi girma yawan adadin famfo, ƙananan kai. Fahimtar kan famfo yana da mahimmanci saboda yana taimaka wa injiniyoyi su tantance aikin famfo, zaɓi fam ɗin da ya dace don aikace-aikacen da aka bayar, da ƙira ingantaccen tsarin jigilar ruwa.

Abubuwan da ke cikin Pump Head

Don fahimtar lissafin kan famfo, yana da mahimmanci a rushe abubuwan da ke ba da gudummawa ga jimillar shugaban:

Shugaban a tsaye (Hs)Kai tsaye shine nisa a tsaye tsakanin tsotsawar famfo da wuraren fitarwa. Yana lissafin yuwuwar canjin makamashi saboda haɓakawa. Idan wurin fitarwa ya fi wurin tsotsa, kai tsaye yana da inganci, kuma idan yana ƙasa, kai tsaye mara kyau.

Shugaban Saurin (Hv)Shugaban saurin gudu shine makamashin motsa jiki da ake bayarwa ga ruwa yayin da yake motsawa ta cikin bututu. Ya dogara da saurin ruwan kuma ana ƙididdige shi ta amfani da ma'auni:

Hv=V^2/2g

Inda:

Hv= Shugaban gudun mita (mita)
V= Gudun ruwa (m/s)
g= Haɗawa saboda nauyi (9.81m/s²)

Shugaban matsin lamba (Hp): Shugaban matsa lamba yana wakiltar makamashin da aka ƙara zuwa ruwa ta hanyar famfo don shawo kan asarar matsa lamba a cikin tsarin. Ana iya ƙididdige shi ta amfani da lissafin Bernoulli:

Hp=Pd-Ps/ρg

Inda:

Hp= Shugaban matsi (mita)
Pd= Matsi a wurin fitarwa (Pa)
Ps= Matsi a wurin tsotsa (Pa)
ρ= Yawan ruwa (kg/m³)
g= Haɗawa saboda nauyi (9.81m/s²)

Shugaban gogayya (Hf): Shugaban juzu'i yana lissafin asarar makamashi saboda gogayyawar bututu da kayan aiki a cikin tsarin. Ana iya ƙididdige shi ta amfani da ma'aunin Darcy-Weisbach:

Hf=fLQ^2/D^2g

Inda:

Hf= Shugaban juzu'i (mita)
f= Darcy friction factor (mara girman girma)
L= Tsawon bututu (mita)
Q= Yawan gudu (m³/s)
D= Diamita na bututu (mita)
g= Haɗawa saboda nauyi (9.81m/s²)

Jimillar Head Equation

Jimillar shugaban (H) na tsarin famfo shine jimlar duk waɗannan abubuwan:

H=Hs+Hv+Hp+Hf

Fahimtar wannan ma'auni yana bawa injiniyoyi damar tsara ingantaccen tsarin famfo ta hanyar la'akari da abubuwa kamar ƙimar kwararar da ake buƙata, girman bututu, bambance-bambancen haɓaka, da buƙatun matsa lamba.

Aikace-aikacen Lissafin Head Pump

Zaɓin famfo: Injiniya suna amfani da lissafin kan famfo don zaɓar fam ɗin da ya dace don takamaiman aikace-aikacen. Ta hanyar ƙayyade jimillar shugaban da ake buƙata, za su iya zaɓar famfo wanda zai iya biyan waɗannan buƙatun yadda ya kamata.

Tsarin Tsarin: Lissafin kan famfo yana da mahimmanci wajen tsara tsarin jigilar ruwa. Injiniyoyin na iya girman bututu kuma su zaɓi kayan aiki masu dacewa don rage asarar rikice-rikice da haɓaka ingantaccen tsarin.

Ingantaccen Makamashi: Fahimtar shugaban famfo yana taimakawa wajen inganta aikin famfo don ingantaccen makamashi. Ta hanyar rage kai da ba dole ba, injiniyoyi na iya rage yawan kuzari da farashin aiki.

Kulawa da Gyara matsala: Kula da kan famfo na tsawon lokaci zai iya taimakawa gano canje-canje a cikin aikin tsarin, yana nuna buƙatar kulawa ko magance matsalolin kamar toshewa ko leaks.

Misalin Lissafi: Ƙayyade Jimillar Shugaban famfo

Don kwatanta manufar lissafin kan famfo, bari mu yi la'akari da sauƙaƙan yanayin da ya ƙunshi famfo na ruwa da ake amfani da shi don ban ruwa. A cikin wannan yanayin, muna so mu ƙayyade jimillar famfon da ake buƙata don ingantaccen rarraba ruwa daga tafki zuwa filin.

Abubuwan da aka Basu:

Bambancin Tsayi (ΔH): Tsayin nisa daga matakin ruwa a cikin tafki zuwa matsayi mafi girma a filin ban ruwa shine mita 20.

Asarar kai mai jujjuyawa (hf): Asarar rikice-rikice saboda bututu, kayan aiki, da sauran abubuwan da ke cikin tsarin sun kai mita 5.

Shugaban Gudun Wuta (hv): Don kula da tsayayyen kwarara, ana buƙatar takamaiman kan gudun mita 2.

Shugaban matsin lamba (hp): Ƙarin shugaban matsa lamba, kamar don shawo kan mai sarrafa matsa lamba, mita 3 ne.

Lissafi:

Ana iya ƙididdige jimlar shugaban famfo (H) da ake buƙata ta amfani da ma'auni mai zuwa:

Jimlar Shugaban famfo (H) = Babban Bambanci/Tsaye Shugaban (ΔH)/(hs) + Rasuwar kai (hf) + Shugaban Gudun (hv) + Shugaban matsin lamba (hp)

H = mita 20 + 5 mita + 2 mita + 3 mita

H = 30m

A cikin wannan misali, jimlar famfon da ake buƙata don tsarin ban ruwa shine mita 30. Wannan yana nufin famfo dole ne ya iya samar da isasshen makamashi don ɗaga ruwa na mita 20 a tsaye, shawo kan asarar rikice-rikice, kula da wani saurin gudu, da kuma samar da ƙarin matsa lamba kamar yadda ake buƙata.

Fahimta da ƙididdige ƙididdiga daidai kan jimlar famfo yana da mahimmanci don zaɓar famfo mai girman da ya dace don cimma ƙimar da ake so a daidai kan kai.

A ina zan iya samun adadi na famfo?

Alamar shugaban famfo yana nan kuma ana iya samuwa a cikintakardun bayanaina duk manyan kayayyakin mu. Don samun ƙarin bayani game da bayanan fasaha na famfunan mu, tuntuɓi ƙungiyar fasaha da tallace-tallace.
