Imingcele eyinhloko nezinkinga ezivamile zephampu ye-hydraulic

1.6.11 i-flange yokufaka nochungechunge lwe-shaft extension dimension

I-flange yokufaka yepompo ye-hydraulic ihlanganisa idayimane, isikwele, i-polygon (okuhlanganisa indilinga), isandiso se-cylindrical shaft, 1:10 isandiso se-conical shaft esinentambo yangaphandle kanye ne-involute spline ene-engeli yokucindezela engu-30 °. Ukuze kube lula ukuklama, ukukhiqiza kanye nokugcinwa, i-flange yokufaka engenhla kanye nobukhulu bokunwetshwa kwe-shaft yenziwe i-serialized futhi yafana. Ku-GB / T 2353-2005 "ipompo ye-hydraulic kanye ne-hydraulic motor mounting flange kanye nochungechunge lwe-shaft extension dimension kanye nekhodi yokumaka", iphampu kanye ne-motor mounting flange kanye nochungechunge lwe-shaft extension dimension kanye nendlela yokumaka icacisiwe.

1.6.12 Imodi yokushayela kanye nezidingo zomguquli oyinhloko

Isistimu ye-hydraulic yemishini engaguquki, ipompo ye-hydraulic ivame ukuqhutshwa yinjini kagesi. Isistimu ye-hydraulic yemishini yokuhamba kakhulu isebenzisa injini evuthayo yangaphakathi ukushayela iphampu ye-hydraulic.

(1) Izimfuneko zamamotho

① Ngenxa yokuthi iphampu ye-hydraulic ivamise ukuqaliswa ngaphansi kokungalayishi, i-torque yokuqala yemoto ayiphezulu kakhulu, ukushintshwa komthwalo kuzinzile, futhi izikhathi zokuqala aziningi, ngakho-ke i-Y Series yekheji yohlobo lwe-asynchronous motor ingasetshenziswa. Lapho amandla esistimu ye-hydraulic enkulu futhi umthamo wegridi yamandla encane, i-rotor motor yesilonda ingasetshenziswa. Kupompo ye-hydraulic ene-variable frequency flow regulation scheme, i-AC asynchronous motor elawulwa yi-frequency converter kufanele isetshenziselwe ukushayela iphampu ye-hydraulic.

Indawo yokusebenza yepompo ye-hydraulic ihlukile, futhi izidingo zohlobo lokuvikela zemoto yayo yokushayela zihlukile: injini evulekile (uphawu lokuvikela yi-ipi1) kufanele lusetshenziswe endaweni ehlanzekile neyomile; injini yokuvikela (uphawu lokuvikela yi-IP22 ne-IP23) kufanele lusetshenziswe endaweni ehlanzekile; Injini evaliwe kufanele isetshenziswe endaweni eswakeme, enothuli, eshisa kakhulu, edlekayo noma emoyeni nasemvuleni endaweni ejwayele ukuqhuma, kufanele kusetshenziswe injini engaqhumi (efana ne-D Ⅱ cT4).

② Ijubane lemoto kufanele lihambisane nesivinini sephampu ye-hydraulic. Ukuhlanganisa kuvame ukusetshenziswa phakathi kwenjini kanye nephampu ye-hydraulic, futhi isivinini semoto kufanele sibe phakathi kwebanga lejubane elingcono kakhulu lepompo ye-hydraulic. Uma kungenjalo, ukusebenza kahle kwepompo ye-hydraulic kuzoncishiswa.

Uhlobo olufanayo lwenjini enamandla afanayo (amandla) ngokuvamile lunejubane elihlukile lokukhetha. Injini yejubane eliphansi inamapheya amaningi wezigxobo, usayizi omkhulu nesisindo, intengo ephezulu, futhi idinga ukususwa kwephampu enkulu (uma kwenzeka ukugeleza okuthile); high speed motor kuphambene. Ngakho-ke, isivinini se-motor kufanele sicatshangelwe kanye nokugeleza nokuhamba kwepompo.

③ Amandla emoto

a. Lapho iphampu ye-hydraulic isebenza ngaphansi kwengcindezi elinganiselwe nokugeleza, amandla enjini angakhethwa ngokuya ngamandla okushayela wepompo ye-hydraulic kusampula yomkhiqizo wepompo ye-hydraulic.

b. Uma ipompo ye-hydraulic isebenza ngaphansi kwesinye ingcindezi nokugeleza, amandla emoto angabalwa nge-equation (1-18), futhi injini efanelekile ingakhethwa.

I-Pi = (△pq)/(60η)(kW) (1-18)

Lapho △ P -- umehluko wengcindezi phakathi kokungena nokuphuma kwepompo ye-hydraulic (uma ingcindezi yokungena yepompo iseduze noziro, ukucindezela kokuphuma kokuphumayo kokusebenza kwephampu kungasetshenziswa ukufaka esikhundleni △ P), i-MPa;

Q -- ubuningi bepompo ye-hydraulic, L / min;

η - ukusebenza kahle okuphelele kwepompo ye-hydraulic,%.

c. Uma amandla okushayela epompo ye-hydraulic eshintsha kakhulu, amandla adingekayo esiteji ngasinye sokusebenza kufanele abalwe ngokulandelana, bese i-PCP yamandla ephakathi kufanele ibalwe ngokusho kwe-equation (1-19), bese kuthi amandla okushayela epompo ye-hydraulic kufanele anqunywe. Njengoba i-motor ingalayishwa kakhulu ngesikhathi esifushane, amandla emoto kufanele abe makhulu kunamandla ajwayelekile abalwe ngenhla, futhi amandla amakhulu akufanele abe ngaphezu kwezikhathi eziyi-1.25 zamandla alinganisiwe wemoto.

(kW) (1-19)

Lapho i-PI -- amandla adingekayo esigabeni sokusebenza se-i-th somjikelezo ngamunye wokusebenza, kW;

Ti -- ubude besigaba sokusebenza, S.

d. Ngohlelo lokujikeleza olushintshashintshayo olusheshayo noluhamba kancane olunamafutha ahlinzekwa ngamaphampu aphindwe kabili, avame ukusetshenziswa kubunjiniyela, amandla okushayela ezigaba zokusebenza ezisheshayo nezinensayo kufanele abalwe ngokulandelana. Iphampu yokuqala kufanele ikwazi ukuthwala umthwalo ophezulu (ingcindezi × ukugeleza) kunepompo yesibili; umthamo ophelele wepompo eningi akufanele udlule i-torque engathwala isandiso se-shaft sepompo.

(2) Lapho iphampu ye-hydraulic iqhutshwa injini evuthayo yangaphakathi, kunezimo ezimbili ezihlukene: enye ukuthi ipompo ye-hydraulic iyingxenye kuphela yomthwalo wokushayela wenjini yangaphakathi evuthayo; enye iwukuthi wonke amandla enjini evuthayo yangaphakathi asetshenziselwa ukushayela iphampu ye-hydraulic.

① Uma iphampu ye-hydraulic iyingxenye kuphela yomthwalo wokushayela wenjini evuthayo yangaphakathi, amandla enjini evuthayo yangaphakathi makhulu, angahlala ehlangabezana namandla adingekayo wepompo ye-hydraulic. Ijubane lenjini evuthayo yangaphakathi kufanele lihambisane nesivinini esingcono kakhulu sepompo ye-hydraulic. Injini evuthayo yangaphakathi enesivinini esiphezulu ivamise ukuba nedivayisi yokwehlisa amandla ukuze yenze iphampu ye-hydraulic isebenze ngesivinini esiphezulu.

② Uhlelo wonke amandla enjini evuthayo asetshenziselwa ukushayela iphampu ye-hydraulic lubizwa ngokuthi i-full hydraulic drive system. Uhlelo olugcwele lokushayela okudonsa amanzi nge-hydraulic lwezimoto nemishini yokuhamba luvamise ukusebenzisa uhlelo lokulawula isivinini sevolumu yephampu eguquguqukayo noma i-motor eguquguqukayo ukuze kuhlangatshezwane nezidingo zokushintsha isivinini esikhulu semishini yokuhamba. Isivinini esiphezulu senjini evuthayo yangaphakathi sizohlangabezana nokugeleza okukhulu okudingekayo ohlelweni futhi akumele sidlule isivinini esiphezulu esivumelekile sepompo ye-hydraulic. Uma isivinini senjini evuthayo yangaphakathi siphezulu kakhulu, idivayisi yokunciphisa kufanele isethwe. Amandla aphezulu enjini evuthayo yangaphakathi kufanele abe phezulu kancane kunalawo adingwa isistimu ye-hydraulic.
