Uxinzelelo hydrostatic

Hydrostatic - yenye amacandelo hydraulic ukufunda likarhulumente lizama kunye noxinzelelo engamanzi efunyenwe engamanzi ukuphumla kwi imiphezulu eyahlukileyo.

uxinzelelo Hydrostatic - ingqiqo ibalulekileyo hydrostatics. Khawucinge nje nevolumu fluid olithandayo zilingana. Ngaphakathi kule ncwadi wesishwankathelo indawo A kunye nasengqondweni ulahlule phakathi yi-moya edlula kwindawo A. Kule nxalenye inqwelomoya ekwahluleni kwindawo S kunye iziko kwindawo A. Makhe ukucima esinye isiqingatha umthamo kwaye ubuyisele force apho wenze imali eseleyo, amandla counterbalancing F. ngenxa yoko, kulwelo kwisiqingatha sesibini iya kuqhubeka kuphumla.

Ngoku aqale ukunciphisa kwindawo S ukuze sihlale akhombe A ngaphakathi kuyo. Kunye nokwehla eyaneleyo indawo A ingqamana kummandla S. ke uxinzelelo kwenyeindawo A iya kumiselwa P ifomula (A) = lim iDF / DS xa DS kuyaphela zero.

Ngoko ke uxinzelelo eqongeni S, iya kulingana nemali xi umthwalo emagxeni onke amanqaku akwi kumphezulu. Oko kukuthi, ngamanye amazwi: p = F / S. uxinzelelo Hydrostatic - nasebulawini into elingana QUOTIENT kootishala F kwindawo S.

Isizathu sokuba uxinzelelo hydrostatic ke umlinganiso ulwelo kunye noxinzelelo olusetyenziswa kumphezulu engamanzi. Ngenxa yoko, uxinzelelo olubangelwa ubunzima yamanzi kunye uxinzelelo lwangaphandle - iintlobo uxinzelelo hydrostatic. Ukuba ulwelo wasibeka piston aze asebenzise umkhosi kuyo, ke ngoko, Kakade ke, ngaphakathi uxinzelelo ukunyuka fluid. Phantsi kweemeko eziqhelekileyo, womoya Sehla ulwelo. Ukuba uxinzelelo kumphezulu ulwelo ngezantsi womoya, xi kuthiwa gauge.

Le nto ilulwelo zilingana ukuba yonke imikhosi uxinzelelo emele nawuphi na umthamo omncinane ngokwaneleyo na ulwelo, olinganayo kunye nabanye.

Cinga uxinzelelo closer hydrostatic kunye neempawu zayo:

• Malunga nayo nayiphi na indawo, ngokuqgibeleleyo ezibanjiswe eya kumda wesangqa xi hydrostatic ulwelo ngqo ngaphakathi na umthamo wayo kwaye nkqo kwisiza ekhethiweyo kwi kwikhusi.

Masibe lo propati: makhe sicinge ukuba engile apho amandla lisetyenziswa kwi ariya ethile, kungekhona umgca othe ngqo. Thina zimele P amandla njengoko P (eqhelekileyo), P (netangent). Makhe sicinge ukuba icandelo tangential ayikho zero, ngoko ke ulwelo kufuneka kumpompoza phantsi kwempembelelo yayo i ukuthambeka, kodwa Liphumle abakwindawo. Ngoko ke kwisigqibo sokuba ilayini ezibambanayo kodwa azikweli ilingana zero nefuthe ingcinezelo kwenzeka site nkqo. Le propati kubonakaliswa.

• Ubukhulu yengcinezelo hydrostatic efanayo kuwo onke amacala.

Masibe lo mhlaba xi hydrostatic: khetha engenasizathu tetrahedron screen elulwelo, ezimbini kuzo ungqamane-moya ukulungelelanisa moya, kwaye eyesithathu ikhethiwe ezinemvume. Isiseko afumane unxantathu tye. Isenzo ulwelo ebusweni ngalinye lenza: X * (P), Y * (P), Z * (P) agcinwe kwi sizinze elulwelo, kangangokuba kufikelelwe kwisiphumo lilonke isenzo forces 0.

E * (x) = 0

X * (P) DZ -X * (P) de isono = 0,

E * (y) = 0, E * (z) = 0

Z * (P) DX -X * (P) de cos a = 0

kucacile ukuba DZ = de izono, DX = de cos a

kungoko: X * (P) = E * (P), Z * (P) = E * (P)

output: X * (P) = Y * (P) = Z * (P) = E * (P)

Le propati kubonakaliswa. Ukususela kumgca lwakhethwa ngokuqgibeleleyo, le ukulingana lisebenza nangaliphi na ixesha.

• Uxinzelelo hydrostatic kukuba kisekiyo ngqo ubunzulu. Ngenxa yokwanda uxinzelelo Ubunzulu indawo kuza kwanda, kwaye kukho ukwehla ubunzulu emanzini - ulwando.

Nayiphi na ingongoma engamanzi, zilingana uyahlangabezana equation alandelayo: j + p / g = j (o) + p (o) / g = H, apho j - nokulungelelanisa yencopho banikwa, j (O) - Inanai elihambiselanayo lika phezu kulwelo, p, kwaye p (o) - ukuphakama eentsika, g - ubunzulu ulwelo ezithile, H - hydrohead.

Ngenxa utshintshwano sinokuyifumana: r = p () + g [j (0) -j] okanye p = p (o) + GH

apho h - ubunzulu ubhaptizo indawo, yaye GH - nje ubunzima umhlathi elilinganayo ulwelo ukuya h ubude kunye nokuba kule ndawo unit isiseko. Lo mhlaba ke igama yengcinezelo hydrostatic yoMthetho Pascal kaThixo.
