Classification and expression of hydraulic pump and motor

1.3.1 klasifikasie

(1) Kunezinhlobo eziningi zamapompo namamotho e-hydraulic, futhi izindlela zokuhlukanisa kanye namagama zihluka ngokugxila.

E ka se ka a kgaogana ka mofuta wa gear, mofuta wa vane, mofuta wa plunger le mofuta wa screw

Ngokweguquguquko kwesikhathi sokusebenza, ivolumu ye-liquid engena futhi ephumayo ingalungiswa, engahlukaniswa ibe uhlobo lwezilinganiso noluhlanganisayo.

Ngaphezu kwalokho, ngokusho kwesivinini sayo kanye ne-torque, imoto ye-hydraulic ivamise ukuhlukaniswa ibe izinhlobo ezintathu: uhlobo olusheshayo olunomthamo omncane kanye nohlobo oluphansi olunomthamo omkhulu, kanye nemoto yokuhamba engakwazi kuphela ukwenza ukujika okulinganiselwe. Ngokuvamile, imoto enesivinini esilinganisiwe esiphezulu kune-500 R / min ibizwa ngokuthi imoto esheshayo, kanti imoto enesivinini esilinganisiwe esiphansi kune-500 R / min ibizwa ngokuthi imoto ephansi. Izinhlobo eziyisisekelo zezimoto ze-hydraulic ezisheshayo zifaka uhlobo lwegear, uhlobo lwe-screw, uhlobo lwe-vane kanye nohlobo lwe-axial piston. Izakhiwo zazo zifana nezefana zezimoto ze-hydraulic, futhi izimiso zazo zokusebenza ziyaphindaphindwa. Nokho, ngenxa yezinjongo zazo ezihlukene zokusetshenziswa, kunezinto eziningi ezihlukile ezakhiweni zazo, ezingavamile ukuphindaphindwa ngqo. Imoto ye-hydraulic esheshayo inezinzuzo zokushesha, umthamo omncane wokuphenduka, kulula ukuqala nokuphuma, ukuphendula okukhulu kokulungisa nokushintsha, kodwa umthamo wokukhipha uncane (kuphela emithonjeni eyishumi kuya kweziyikhulu ze-n · m). Uma uhambisa umthwalo ophansi, kudingeka idivayisi yokukhuphuka nokwehla. Uhlobo oluyisisekelo lwemoto ephansi uhlobo lwe-plunger, kuhlanganisa ukwenziwa okukodwa nokwenziwa okuningi. Imoto ye-hydraulic ephansi inezinzuzo zokukhishwa okukhulu, isivinini esiphansi, umthamo omkhulu wokukhipha (ufinyelela ezinkulungwaneni kuya kwezinkulungwane eziningi ze-n · m), futhi ingaxhunywa ngqo nomshini wayo wokusebenza ngaphandle kwedivayisi yokwehla, kodwa ivolumu yayo inkulu. Imoto ye-hydraulic yokuhamba ingahlukaniswa ibe uhlobo lwe-piston nohlobo lwe-vane, kanti uhlobo lwe-vane lusetshenziswa kakhulu. Isakhiwo semoto ye-hydraulic yokuhamba silula kunezimoto ze-hydraulic ezijikayo eziqhubekayo. Izinzuzo ezivelele zemoto ye-hydraulic yokuhamba ukuthi umgqa wokukhipha uqondile uhambisa umthwalo ukuze uhambise, ngaphandle kwanoma iyiphi imishini yokushintsha isivinini, umthamo wokukhipha ungafinyelela ezinkulungwaneni ze-n · m, futhi isivinini esincane esizinzile singafinyelela ku-0.001 rad / s.

1.3.2 grafiese simbole

(1) Izi zimpawu zomfanekiso zamaphampu namamotho ajwayelekile we-hydraulic kanye nencazelo yazo. Imidwebo ye-schematic yezingxenye ze-hydraulic nezinhlelo, kuhlanganise namaphampu namamotho e-hydraulic, ivamise ukudwetshwa ngezimpawu zomfanekiso ezijwayelekile. Njengoba lezi zimpawu zomfanekiso zimele kuphela umsebenzi, indlela yokusebenza (ukulawula) kanye nokuxhumana ngaphandle kwezingxenye ze-hydraulic, kodwa hhayi isakhiwo esithile, amapharamitha okusebenza, indawo yangempela yokuxhumana kanye nendawo yokufaka izingxenye, zisetshenziswa ukuveza imisebenzi yezingxenye ezihlukene ohlelweni kanye nokwakheka, uxhumano lwe-oli kanye nomgomo wokusebenza kohlelo lonke. Zilula futhi zicacile, futhi kulula ukuzidweba nokushintshisana ngobuchwepheshe.

Ngonyaka ka-1965, 1976, 1993 no-2009, iChina yakhuluma izindinganiso zezimboli ze-hydraulic. Izindinganiso zamanje ngu-GB / T 786.1-2009 izinhlelo zamandla kanye nezinto - Izimboli zezimbozo nezichazi - Ingxenye 1: Izimboli zezimbozo zokusetshenziswa jikelele kanye nokucubungula idatha. Lezi zindinganiso ziqinisekisa izinto eziyisisekelo zezimboli ezahlukene (kuhlanganisa umugqa, uxhumano kanye ne-pipe joint, indlela yokugeleza kanye nokuqondiswa, izinto eziyisisekelo zomshini, izinto zokulawula, izinto zokulawula, njll.), futhi zifaka imithetho yokwakha nokusetshenziswa kwezinto ze-hydraulic nezepneumatic (i-hydraulic: ivali, ipompo kanye nemoto, isilinda, izinsiza; i-pneumatic: ivali, i-air compressor kanye nemoto, isilinda, izinsiza) nezimboli esichazweni (kuhlanganisa Izimboli ze-CAD zethulwa ngendlela ye-appendix enolwazi.

Izi zimpawu zomfanekiso zamapompo namamotho ajwayelekile akhishwe ku-GB / T 786.1-2009 zikhonjiswa etafuleni elingezansi, futhi incazelo yezimpawu zomfanekiso ilandelayo.

④ Iphawu le-grafiki le-hydraulic pump limeleka ngecango elihlanganisa ne-triangle eliqondile elilodwa noma ama-triangle amabili aqondile. Umkhombandlela ophumayo we-triangle eqondile ubonisa umkhondo we-oyili enezinga. I-triangle eqondile eyodwa ye-pump eyodwa, ama-triangle amabili eqondile ye-pump emibili. Imigqa em vertical phezulu naphansi ye-cango imele izikhonkwane zokukhipha amafutha nezikhonkwane zokuthola amafutha (ama-port amafutha) ngokuhambisana. Akukho mkhombandlela we-pump ye-quantitative, umkhombandlela we-pump ye-variable. Imigqa emibili nemikhombandlela ye-arc eceleni kwe-cango imele i-shaft yokushayela ye-pump kanye nokunyakaza kwe-rotary ngokuhambisana.

② I-graphic symbol ye-hydraulic motor imelekezelwa ngu-circle enezikwele eziphakeme ezilinganayo noma ezimbili ezikwele eziphakeme ezilinganayo. I-arrow yangaphakathi ye-triangle elinganayo ibonisa umkhombandlela we-oli pressure. I-triangle elinganayo eyodwa imele i-motor eyodwa, kanti ezimbili ezikwele ezilinganayo zimele i-motor emibili. Imigqa em vertical phezulu naphansi ye-circle imele i-oli inlet ne-oli outlet ngokulandelana. I-motor engena-arrow iyimotor ye-quantitative, kanti i-motor enarrow iyimotor ye-variable. Ama-arrow amabili aphakathi nendawo kanye ne-arc eceleni kwe-circle akhombisa i-motor drive shaft kanye ne-rotary motion ngokulandelana.

(2) Iziqinisekiso zokusebenzisa izimpawu zomfanekiso, lezi ziqinisekiso kufanele zicatshangelwe lapho kusetshenziswa i-GB / T 786.1-2009 ukudweba umdwebo weschematic wezinto ezisebenza ngamanzi nezinhlelo.

① Ngokwezinga nezidingo zomdwebo, usayizi wezimpawu zomfanekiso wezithako ungashintshwa ngokuya ngempahla efanele ukuze udwebele, ngokusekelwe kumgomo wokucacile nokuhle.

② Izi ziqephu nezichazi zecircuit ngokuvamile zibhaliwe esimweni esingasebenzi ngaphandle kokukhuthazwa (njengokuthi isikhundla sokusebenza se-electromagnetic directional valve ngemuva kokuphazamiseka kwamandla).

③ On the premise of not changing the meaning of the initial state defined in the standard, the direction of the component can be drawn according to the specific situation of horizontal turnover or 90 ° rotation, but the hydraulic tank must be drawn horizontally and the opening upward.
