Spool - ngezinga elithile isisindo ezinsukwini ubudala

Nge ukwedlulela sonke isintu Kancane kancane uhlelo SI kuyinto kancane kancane into yesikhathi esidlule, Slavic eziningi zasendulo ukukala isisindo kanye nobude. Phakathi kwabo slide - ngezinga elithile isisindo, limatasa lisetshenziswa kusukela ekuqaleni nesishiyagalombili futhi kuze kube namathathu banesifo esibi kwekhulu lamashumi amabili.

Spool - kuyini

Spool ezinsukwini ubudala okuthiwa isisindo isilinganiso kuncuma isisindo metal (ngokuvamile zegolide nezesiliva). Isilinganiso ukusetshenziswa namhlanje nomunye igremu spool kuhlaziywe 4.3 amagremu noma ingxenye 1/96 iphawundi (Russian).

Indaba isisindo isilinganiso okuthiwa spool

Namuhla, ososayensi abakwazi ngokuqiniseka lapho igama kwaba elithile isisindo, njengoba spool. Kucatshangwa kwavela leli gama kusukela esikhathini Kievan Rus. Njengoba kwaziwa ukuthi eyaziwa phakathi nesikhathi Prince Vladimira Velikogo (X leminyaka), omunye ezincane zemali zegolide kwesikhulu ngokuthi "zlatnik".

Mhlawumbe, lokhu uhlamvu kamuva ziye ngenkuthalo esetshenziswa njengendlela slug lapho enesisindo izihloko esenziwe eziyigugu. Futhi kancane kancane, kusukela igama uhlamvu lwemali isusela igama layo of "spool" - ngezinga elithile isisindo esetshenziswa sokunquma nenqwaba izihloko of ensimbini eyigugu.

Lapho kukhulunywa ngaye okokuqala ebhaliwe spool njengoba isisindo okungenani ngomhla XIII leminyaka. Kokunye kwemibhalo yakhe ibhizinisi, Prince Mstislav ka Smolensk isebenzisa igama elithi "spool" ingasi njengelizwi lomuntu nje igama uhlamvu, kodwa njengoba isilinganiso esithile isisindo. Mhlawumbe, inkathi eqondile nge spools kulinganiswa Ingxenye okumsulwa ensimbini eyigugu e uhlamvu oluthile noma enye into zegolide nezesiliva.

Ngokuhamba kwesikhathi, ama-slide ukuthandwa njengoba isilinganiso esithile isisindo ukusakaza. Futhi nge-slide 1711 lithole isimo izinyathelo ezisemthethweni isisindo akuzona igolide nje nezesiliva kuphela kodwa futhi nezinye izinsimbi eziyigugu kanye lasetshenziswa kwaze kwaba ngu-1927

Futhi, kukhona umbono okunye ukuthi igama elithi "spool" lisuselwa egameni metal igolide. Nokho, lokhu kubonakala kungeke, kusukela spool liyasetshenziswa ukukala isisindo platinum nesiliva.

Kala isisindo lokhu kwaba nesandla ukuvela okuthiwa slide valve uhlelo izibonelo zalokho, okuyinto kwakwandile eMbusweni Russian.

amasampula Spool uhlelo

Lokhu amasampula uhlelo kwenza ukuba sithole khona amatshe ayigugu ngendlela ingxubevange unikezwa, futhi nenombolo yabo. Ngamanye amazwi, metal isampula esihle (ebumsulweni nasebunyeni) wasiza ukuchaza spool. Kala isisindo lokhu kwaba nesandla ekwakhekeni valve slide we isampula igolide, kanye slide umphini we isampula esiliva.

Ngakho ngegolide elihlanzekile ngaphandle ukungcola (okwamanje 999 isampula) ayebhekwa njengengxenye isisindo ensimbini eyigugu ku spool 96. Lokhu kwakusho ukuthi uma indlela yokwakheka metal sithathwa 100%, bese 100% igolide. Nokho, sehla valve simiso, inani eliphezulu lwezinqubo amasampula kwaba 100%, futhi amayunithi 96 we ensimbini eyigugu. Futhi uma wonke 96 kubo babe yizinkulungwane igolide - kwensimbi lihlanzekile futhi kwadingeka isampula 96 (okwamanje 999).

Emincane kakhulu slide umphini ukuwohloka engu-56 (okwamanje 585), ngoba 56 kuphela izingxenye igolide, nokunye - ukungcola ka nezinye izinsimbi. Sekukonke, kwakunama-eziyisithupha spool Antique amasampuli igolide.

Namuhla abanikazi ujabule igolide yokukhiqiza prerevolutionary ungase uphawule kubo spool isampula naleso sikhathi. Ukuze wakufaka uhlelo yesimanje futhi ufunde imikhiqizo metal okumsulwa, singasebenzisa ifomula ilula: A / 96 * 1000 = B. Kulokhu A - spool isampula, no-B - yesimanje.

Ukumeda esiliva ubumsulwa spools futhi azihlukile kakhulu kusukela igolide. Nokho ekuqaleni yayikhona lemali enkulu amasampula metal - amaningi njengoba ayisishiyagalolunye (72 ukuya ku-95). Nokho, ekupheleni XIX yabo kakhulu ziyancipha ezine (84 ukuya ku-95).

Njenge-igolide, spool esiliva kwasiza ekunqumeni inani ezigxotsheni metal ku amayunithi 96. Namuhla ukudluliswa spool pre-revolution yesimanje esiliva isampula kungaba indlela efanayo nanjengoba ukuthi egolide.

slide ukuhlanganisa nezinye izilinganiso isisindo ezinsukwini ubudala

Spool - abanesibalo: 1/96.

Pud - slide: 1/3840.

ULoti - slide: 1/3.

Pound - slide: 1/96.

Spool nezinyathelo yesimanje isisindo

Uma eqhathaniswa isisindo samanje amayunithi elilodwa spool cishe 4.3 amagremu (SR uhlelo).

Ngokusho British ekhemisi uhlelo izinyathelo isisindo we spool ilingana cishe 0,01143 lb noma 0.14 troy amamilimitha.

Mayelana isisindo salesi simiso izinyathelo e-United States, slide esisodwa - mayelana 0.151 i-ounce, noma 0.01 US iphawundi.

Amazwi "Small kodwa eziyigugu" nezinye isilinganiso, isisindo

Lesi isilinganiso nesisindo kwaba zithandwa lokhokho, ngokuvamile yakhiwa amazwi akhe. Ngokwesibonelo, lapho bafuna elichaza ubukhulu elincane, kodwa into eyigugu kakhulu sebenzisa laziwe kubo bonke kusukela ebuntwaneni ethi.

Kwakukhona futhi ukuhluka kancane Analogue yayo: ". Mal valve, kodwa onohlonze"

Kunenye zwi efanayo, futhi wanikezela izinto ezincane kodwa obalulekile. It is ngokugcwele kuboniswe isimiso ukuthi akukho usayizi kubalulekile futhi ezibalulekile.

Ukuchaza ukubaluleka impilo ngabantu, usebenzisa leli zwi:

Futhi njengoba nje ngezinga elithile isisindo spool kuyinto ngokuzinikela okulandelayo ethi:

Namuhla, kudala hhayi ukuya ukunquma ubumsulwa noma isiliva isampula slide. Kala isisindo lokhu kuye kwaba yingxenye yomlando. Nokho, izwi manje ayenziwa elisetshenziswa sokukhuluma nakuba linencazelo ukuhluka. Manje igama elithi "spool" waba izingxenye igama distributor, kodwa lokho omunye indaba.
