Ungabala njani intloko?
Kwindima yethu ebalulekileyo njengabavelisi be-hydraulic pump, siyayazi inani elikhulu lezinto eziguquguqukayo ezifuna ukuqwalaselwa xa ukhetha impompo efanelekileyo yesicelo. Injongo yeli nqaku lokuqala kukuqalisa ukukhanyisa inani elikhulu lezalathi zezobuchwephesha kwi-Hydraulic Pump iPump iPump iPumpTe, iqala ngentloko "yempompo yempompo".
Yintoni intloko yempompo?
I-Pump Intloko, idla ngokubhekiswa kuyo njengentloko okanye intloko yentloko ye-tenamic (i-TDH), imele amandla onke athatyathwayo kwimpompo. Ivumela indibaniselwano yamandla oxinzelelo kunye namandla e-kinetic ukuba impompo idlulisela kulwelo njengoko ihamba ngenkqubo.in i-hifshell, sikwazi ukuchaza i-pumps njengokuphakamisa impompo. Umzekelo ocacileyo kukuba umbhobho wokunyuka okuthe nkqo ngokuhamba ngqo kwivenkile ekuthethwayo. I-fluid iya kuphoswa phantsi kweemitha ezi-5 ukusuka kwindawo yokukhupha impompo ngentloko yeemitha ezi-5. Intloko yempompo ihambelana ngokungathanga kunye nenqanaba lokuhamba. Ixabiso eliphezulu lokuhamba kwempompo, lithoba intloko. Ukuqonda intloko yempompo kubalulekile kuba inceda iinjineli ihlolisisa intsebenzo yempompo, khetha impompo elungileyo yesicelo, kunye nokuyila iinkqubo ezifanelekileyo zothutho.
Izinto zentloko yempompo
Ukuqonda ukubalwa kwentloko kubalo, kubalulekile ukuqhekeza amacandelo egalelo kwintloko iyonke:
Intloko ye-static (HS): Intloko ye-Otic ngumgama othe nkqo phakathi kwempompo yempompo kunye namanqaku akhutshiweyo. Inika ingxelo yotshintsho lwamandla olunokubakho ngenxa yokuphakama. Ukuba indawo yokukhupha iphakamile kunendawo yokunyanzelwa, intloko ye-Otic ilungile, kwaye ukuba isezantsi, intloko eqingqiweyo ayilunganga.
Intloko ye-velocity (HV): Intloko ye-velocity yi-kinetic amandla athathwe kulwelo njengoko ihamba ngemibhobho. Kuxhomekeka kwi-velocity ye-fluid kwaye ibalwa usebenzisa i-equation:
Hv=V^ 2 / 2G
Phi:
- Hv= Intloko ye-velocity (iimitha)
- V= I-fluid velocity (m / s)
- g= Ukukhawulezisa ngenxa yobunzima (9.81 m / s²)
Intloko yoxinzelelo (HP): Intloko yentloko imele amandla ongezelelweyo kulwelo yimpompo yokweyisela ilahleko yoxinzelelo kwinkqubo. Ingabalwa kusetyenziswa i-bernoulli's equation:
Hp=Pd-I-PS / ρg
Phi:
- Hp= Uxinzelelo lwentloko (iimitha)
- Pd= Uxinzelelo kwindawo yokukhupha (pa)
- Ps= Uxinzelelo kwindawo yokuFunda (PA)
- ρ= Ukuxinana kwe-fluid (kg / m³)
- g= Ukukhawulezisa ngenxa yobunzima (9.81 m / s²)
Intloko ye-faction (hf): Ii-akhawunti zentloko yefreyithi yelahleko ye-Froness ngenxa yokufowuna kwe-pirity kunye nezixhobo zenkqubo. Ingabalwa kusetyenziswa i-dantocy-yeisbach iquation:
Hf=flq ^2/D^2g
Phi:
- Hf= Intloko yefreyiti (iimitha)
- f= I-Dericy Fations (i-Dimenced)
- L= Ubude bombhobho (iimitha)
- Q= Ixabiso lokuhamba (M³ / s)
- D= Ububanzi bombhobho (iimitha)
- g= Ukukhawulezisa ngenxa yobunzima (9.81 m / s²)
Iyonke i-equation
Intloko iyonke (H) Inkqubo yempompo sisiphumo sawo onke la macandelo:
H=Hs+Hv+Hp+Hf
Ukuqonda le ntlango ivumela iinjineli zibe yinjineli ye-Pomps ngendlela efanelekileyo ngokujonga izinto ezinje ngenqanaba lokuqhuba elifunwayo, imilinganiselo ye-Pipe, kunye neemfuno zoxinzelelo.
Ukusetyenziswa kwezicelo zokubala zentloko
Ukukhetha impompo: Iinjineli zisebenzisa i-pump yentloko kubalo lokukhetha impompo efanelekileyo yesicelo esithile. Ngokumisela intloko efunekayo, banokukhetha impompo enokuthi ifezekise ezi mfuno.
Uyilo lwenkqubo: I-Pump yeNtlokoba kubabala kubalulekile ekuyileni iinkqubo zothutho lwe-fluid. Iinjineli zinokulinganisa imibhobho kwaye zikhetha izixhobo ezifanelekileyo zokunciphisa ilahleko yokulahleka kunye nokwandisa ukusebenza kwenkqubo.
Ukusebenza kwamandla: Ukuqonda i-pump pump kunceda ekusebenzeni kwempompo yokusebenza kwenkqubo yokusebenza kwamandla. Ngokunciphisa intloko engafunekiyo, iinjineli zinokunciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza.
Ukulungiswa kunye nokulungiswa kwengxaki: Ukubeka iliso kwi-Pump ngaphezulu kwexesha kunokunceda ekufumaneni utshintsho kwinkqubo yokusebenza kwenkqubo, ebonisa isidingo solondolozo okanye ukuvuza ingxaki efana neebhloko okanye ukuvuza.
Ukubala Umzekelo: Ukuchonga intloko yempompo iyonke
Ukubonisa umxholo wokubalwa kwentloko yempompo, masiqwalasele imeko eyenziwe lula ebandakanya impompo yamanzi esetyenziselwa ukunkcenkceshela. Kule meko, sifuna ukumisela ipopu iyonke iyonke efunekayo ekunikezelweni kwamanzi okusebenzayo kwindawo yokugcina amanzi kwintsimi.
Inikezwe iiparameter:
Umahluko wokuphakama (δh): Umgama othe nkqo ukusuka kwinqanaba lamanzi kwindawo yokugcina kwindawo ephezulu kwintsimi yokunkcenkceshela ziimitha ezingama-20.
Ilahleko yeNtloko yeNtloko (HF): Ilahleko yokulahleka kwemali ngenxa yemibhobho, i-fitlengs, kunye nezinye izinto kwinkqubo yenkqubo ukuya kwiimitha ezi-5.
Intloko ye-velocity (HV): Ukugcina ukuhamba okungagungqiyo, intloko ethile ye-2 yeemitha iyafuneka.
Intloko yoxinzelelo (HP): Intloko eyongezelelweyo yoxinzelelo, efana nokoyisa umlawuli woxinzelelo, ziimitha ezi-3.
Ukubala:
Intloko iyonke yentloko (h) ifunelwe ukubalwa kusetyenziswa le quation ilandelayo:
I-pump yompompo (h) = umahluko wokuphakama / intloko eqingqiweyo (δH) / (HS) + (HF) + iNtloko yeNtloko yeNtloko (HF) + iNtloko yeVP)
H = iimitha ezingama-20 + iimitha ezi-5 + 2 yeemitha + iimitha ezi-3
H = iimitha ezingama-30
Kule mizekelo, intloko iyonke iyonke efunekayo kwinkqubo yokunkcenkceshela ziimitha ezingama-30. Oku kuthetha ukuba impompo kufuneka ibe nakho ukubonelela amandla aneleyo okuphakamisa amanzi angama-20 eemitha ngokuthe nkqo, yoyiswa ilahleko yokulahleka, gcina uxinzelelo oluthile, kwaye lubonelele ngoxinzelelo olongezelelekileyo njengoko kufuneka.
Ukuqonda kunye nokubala ngokuchanekileyo intloko yempompo iyonke kubalulekile ukukhetha impompo yedlule ekufezekiseni inqanaba lokuhamba okufunayo kwintloko enesiphumo esifanelekileyo.
