Umbuzo wokuba ipompo ye-hydraulic inokuvelisa uxinzelelo luyisiseko ekuqondeni umsebenzi ophambili wenkqubo ye-hydraulic.Enyanisweni, iimpompo ze-hydraulic zidlala indima ebalulekileyo ekuguquleni amandla omatshini kumandla ombane, ngaloo ndlela kudala uxinzelelo ngaphakathi kolwelo.Ezi zixhobo ziyilelwe ukufunxa kulwelo olwenziwa ngolwelo olwenziwa ngamanzi kunye nokusebenzisa amandla okutyhala ngenkqubo, zenza uxinzelelo olunika amandla oomatshini kunye nezixhobo ezahlukeneyo.Nokuba kusetyenziswa impompo yepiston ebuyelayo okanye impompo yegiya exhomekeke kwizixhobo ezijikelezayo, iimpompo zehydraulic ziyilelwe ukuvelisa amandla afunekayo ekusebenzeni ngokufanelekileyo kwenkqubo yoxinzelelo lwamanzi.
1. Umgaqo wokusebenza wepompo ye-hydraulic
2. Uhlobo lwempompo ye-hydraulic eyenza uxinzelelo
3. Izinto ezichaphazela ukuveliswa koxinzelelo kwiinkqubo ze-hydraulic
1. Umgaqo wokusebenza wepompo ye-hydraulic
Ipompo ye-hydraulic iyinxalenye ebalulekileyo kwinkqubo ye-hydraulic, umsebenzi wayo ophambili kukuvelisa uxinzelelo lokuqhuba ulwelo ngokusebenzisa inkqubo.Ukuguquguquka kwabo kubavumela ukuba basebenzise uluhlu olubanzi loomatshini kunye nezixhobo, bedlala indima ephambili kumashishini afana nokuvelisa, ukwakhiwa kunye nokuthutha.Apha sijonga iimpompo ezimbini eziqhelekileyo zehydraulic ezigqwesileyo kwimveliso yoxinzelelo:
1. impompo yepiston:
Iimpompo zepiston zaziwa ngokubanzi ngokusebenza kwazo ekuveliseni uxinzelelo oluphezulu kwiinkqubo zehydraulic.Basebenza kumgaqo wokubuyisela, apho i-piston ihamba ngasemva nangaphandle ngaphakathi kwe-cylinder.Xa ipiston irhoxa, kwenziwa ivacuum etsala ioyile yehydraulic kwicylinder.Emva koko, njengoko i-piston isanda, icinezela ulwelo, ilunyanzelise ngokuphuma kwempompo kunye nenkqubo ye-hydraulic.
Enye yezona zinto ziluncedo kwiimpompo zepiston kukukwazi ukuvelisa amanqanaba oxinzelelo olwaneleyo, okwenza ukuba zilungele izicelo ezifuna amandla aphezulu, njengoomatshini abanzima bemizi mveliso kunye noxinzelelo lwehydraulic.Ukongeza, iimpompo zepiston eziguquguqukayo zinokuhlengahlengisa ukuphuma kwemveliso ukuze zilawule ngokuguquguqukayo amanqanaba oxinzelelo ngokweemfuno ezithile zesicelo.
2. Impompo yegiya:
Iimpompo zegiya lolunye uhlobo oludumileyo lwempompo ye-hydraulic eyaziwa ngokuba lula kunye nokuthembeka.Ziquka iigiya ezimbini ze-meshing - igiya yokuqhuba kunye negiya eqhutywayo - efakwe ngaphakathi kwecasing yempompo.Njengoko iigiya zijikeleza, zenza amagumbi azoba kulwelo lwehydraulic kwindawo yokungena impompo.Ukujikeleza ke kunyanzelisa ulwelo kwi-outlet, ukudala uxinzelelo olufunekayo ekusebenzeni inkqubo ye-hydraulic.
Ngelixa iimpompo zegesi zingenako ukufikelela kumanqanaba aphezulu oxinzelelo oluphezulu njengeempompo zepiston, ziyagqwesa kwizicelo ezifuna ukuhamba rhoqo kunye nokuzinza kolwelo.Uyilo lwayo oludibeneyo, ixabiso eliphantsi kunye nokugcinwa okuncinci kwenza ukuba kube yinto efanelekileyo yokusetyenziswa kwezoshishino ezahlukeneyo, kubandakanywa izixhobo zokuphatha izinto eziphathekayo, iinkqubo zokulawula kunye neeyunithi zamandla ombane.
Ukukhethwa kwempompo yepiston kunye nempompo yegiya kuxhomekeke kwiimfuno ezithile zenkqubo ye-hydraulic.Iimpompo zepiston zithandwa kwizicelo ezifuna uxinzelelo oluphezulu kunye nokuhamba okuguquguqukayo, ngelixa iimpompo zegesi zixabiswa ngenxa yokulula kwazo, ukuthembeka kunye neendleko-zokusebenza kwizicelo apho ukuhamba okuqhubekayo kunye okufanayo kubalulekile.Ukuqhubela phambili okuqhubekayo kwitekhnoloji yempompo ye-hydraulic iyaqhubeka nokuphucula ukusebenza kwezi zinto zibalulekileyo, ukuqhuba ngokufanelekileyo kunye nokwenziwa kwezinto ezintsha kumashishini ahlukeneyo.
2. Uhlobo lwempompo ye-hydraulic eyenza uxinzelelo
Impompo yehydraulic sisixhobo sokuguqula amandla esiguqula amandla oomatshini abe ngamandla oxinzelelo lolwelo.Umgaqo wayo wokusebenza kukusebenzisa utshintsho lwevolumu evaliweyo ukuthutha ulwelo, kwaye uthembele kumgaqo wokutshintsha umthamo ukuphumeza umsebenzi.Iimpompo zeHydraulic zonke zisebenza ngokusekwe kumgaqo wokutshintsha umthamo wetywina, ngoko ke zikwabizwa ngokuba ziimpompo zehydraulic zokufuduka.
Iimpompo zeHydraulic zahlulwe zaba luhlobo lwegiya, uhlobo lwe-vane, uhlobo lwe-plunger kunye nezinye iintlobo ngokobume bazo.Ngamnye uneempawu zakhe, kodwa asebenze kumgaqo ofanayo.Ukuphuma kwemveliso yepompo ye-hydraulic kunokulungelelaniswa njengoko kuyimfuneko ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza.
Xa ipompo ye-hydraulic isebenza, ijikeleza phantsi kokuqhubela phambili kwe-prime mover, ibangela ukuba umthamo osebenzayo uguquke ngokuqhubekayo, ngaloo ndlela wenze inkqubo yokufunxa ioli kunye nokukhutshwa kweoli.Umyinge wokuhamba kompompo we-hydraulic uxhomekeke kwixabiso lokutshintsha umthamo wegumbi lokusebenza kunye nenani leenguqu kwixesha leyunithi, kwaye ayinanto yakwenza noxinzelelo olusebenzayo kunye neemeko zemibhobho yokufunxa kunye nokukhupha.
3. Izinto ezichaphazela ukuveliswa koxinzelelo kwiinkqubo ze-hydraulic
Isizukulwana soxinzelelo kwiinkqubo ze-hydraulic sichatshazelwa yizinto ezininzi.Nazi ezinye zezinto eziphambili:
**Ubungakanani bomthwalo: Umthwalo omkhulu wenkqubo ye-hydraulic, iphezulu uxinzelelo olufuna ukuveliswa.Umthwalo unokuba nobunzima becandelo lomatshini, ukukhuhlana, okanye okunye ukuchasana.
**I-Viscosity yeoli: I-viscosity yeoli ichaphazela izinga lokuhamba kwayo kunye neempawu zokuhamba kwimibhobho.Ioli ye-viscosity ephezulu iya kunciphisa izinga lokuhamba kunye nokwandisa ukulahleka koxinzelelo, ngelixa ioli ye-viscosity ephantsi iya kukhawulezisa izinga lokuhamba kunye nokunciphisa ukulahleka kwengcinezelo.
** Ubude bombhobho kunye nobubanzi: Ubude kunye nobubanzi bombhobho buchaphazela umgama kunye nokuhamba kweoli kwinkqubo.Imibhobho emide kunye needamitha ezincinci zonyusa ilahleko yoxinzelelo, ngaloo ndlela inciphisa uxinzelelo kwinkqubo.
**Ii-valve kunye nezixhobo: I-valve kunye nezinye izixhobo (ezifana ne-elbows, joints, njl.) zinokuthintela ukuhamba kweoli, okubangela ukulahleka kwengcinezelo.Ngoko ke, xa ukhetha kwaye usebenzisa la macandelo, ingqalelo kufuneka ihlawulwe kwimpembelelo yabo ekusebenzeni kwenkqubo.
** Ukuvuza: Nakuphi na ukuvuza kwinkqubo kuya kunciphisa uxinzelelo olukhoyo njengoko ukuvuza kubangela ukulahleka kweoli kunye nokunciphisa uxinzelelo kwinkqubo.Ke ngoko, kubalulekile ukujonga rhoqo kwaye ugcine inkqubo yakho ukuthintela ukuvuza.
** Utshintsho lobushushu: Ukutshintsha kobushushu kunokuchaphazela i-viscosity kunye neempawu zokuhamba kweoli.Amaqondo okushisa aphezulu anyusa i-viscosity yeoli, eyandisa ilahleko yoxinzelelo;ngelixa amaqondo obushushu asezantsi abhityile i-oyile, nto leyo enciphisa ilahleko yoxinzelelo.Ngoko ke, imiphumo yokushisa kufuneka ithathelwe ingqalelo xa uyila kunye nokusebenza kweenkqubo ze-hydraulic.
**Ukusebenza kweMpompo: Ipompo ye-hydraulic yinxalenye ephambili kwinkqubo eyenza uxinzelelo.Ukusebenza kwempompo (njengokufuduka, uluhlu loxinzelelo olusebenzayo, njl. njl.) luchaphazela ngokuthe ngqo amandla okuvelisa uxinzelelo lwenkqubo.Ukukhetha impompo efanelekileyo kwiimfuno zesixokelelwano sakho kubalulekile ekuqinisekiseni ukusebenza ngendlela eyiyo kwenkqubo.
**Ii-Accumulators kunye ne-Pressure Control valves: Ii-accumulators kunye ne-valve zokulawula uxinzelelo zingasetyenziselwa ukulawula amanqanaba oxinzelelo kwinkqubo.Ngokulungelelanisa la macandelo, ulawulo olusebenzayo kunye nolawulo loxinzelelo lwenkqubo lunokufezekiswa.
Isizukulwana soxinzelelo kwiinkqubo ze-hydraulic sichatshazelwa yizinto ezininzi.Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kunye nokusebenza kakuhle kwenkqubo, abaqulunqi kunye nabaqhubi kufuneka baqwalasele le miba kwaye bathathe amanyathelo ahambelanayo okulungelelaniswa nokulawula.
Impendulo ecacileyo kumbuzo owenziwe ekuqaleni ngu-ewe - impompo ye-hydraulic ngokwenene sisixhobo esisisiseko sokuvelisa uxinzelelo kwi-hydraulic system.Indima yabo ekuguquleni amandla oomatshini kumandla okwenziwa ngolwelo olwenziwa ngamanzi aphantsi komhlaba ibalulekile kumashishini amaninzi, ukusuka kwimveliso nokwakhiwa ukuya kwi-aerospace kunye nemoto.Ukuqhubela phambili okuqhubekayo kwiteknoloji yepompo ye-hydraulic iyaqhubeka nokucokisa kunye nokwandisa ukuveliswa koxinzelelo, okukhokelela kwiinkqubo ezisebenzayo kunye nezizinzileyo ze-hydraulic.Njengoko ishishini liguquka, iimpompo zehydraulic zihlala zingagungqi ekubalulekeni kwazo ekuboneleleni ngamandla ayimfuneko kwizicelo ezingenakubalwa, zigxininisa imeko yazo njengenxalenye ebalulekileyo kumatshini wehlabathi lanamhlanje.
