Simba chemubhotoro uye jira kuwedzera majoini

Simba uye zvinyama Cox compensators Under chemubhotoro simba zvinorevei kugona raro kukurira mitoro siyana dzinoparadza (kuvhunduka, abrasion) iyo iri pasi panguva zvekufambisa, unonyatsoruramisa, uye zvokudya muvira panguva simbi. pfuma iyi kuonekwa anokosha chinoratidza unhu pakati chemubhotoro. Hakurevi kuumba rakasimba chemubhotoro fines inoita kuti tirambe yakakwirira gasi permeability dzavanofanira kuchengeta uye yakakwirira negoho Nokufema muvira. chemubhotoro simba vagara vandifungira chakagadzirwa nokuvhiringidzirwa ivhu vachibatwa zvazvinoita uye hasha zvinorema. Uyere simba ari kuchinja nomusero (PARTICIPLE saizi) pakati murwiyo pakati chemubhotoro panguva muchizviedza uye kushandisa rejira kuwedzera mapfundo. Yainyanya kushandiswa nzira dzokuziva chemubhotoro simba nokutyora pawo kutenderera dhiramu. nzira iyi kuri pakuti chemubhotoro vamwe saizi muenzaniso womumwe saizi anoiswa mukati dhiramu, pashure icho zvayaitenderera paguyo pane akafanorongerwa kumhanya kwenguva zvakafanorongwa nguva. Akakora ose chemubhotoro entrained kumusoro kuwa, uye kunodururwa, saka kuwana chakapatsanurwa Drum uye hasha mitoro vanoparadzwa pakawanda zvichienderana nesimba ravo zvokuimba. Simba kunoratidzwa nokuchinja kukura chemubhotoro zvidimbu somugumisiro pamuedzo. In nyika yedu yava kare nzira mureza kuti kuziva simba chemubhotoro Drum wakatangwa muna Russia mukupera namapfumbamwe remakore E.Sundgrenom. there 2,000 mm mu dhayamita uye 800 mm yakafara ane cylindrical penyika muchimiro yekamuri petsvimbo 25 mm dhayamita pamwe chete rinotsanangurwa therebetween compensators. The Drum iri monica chemubhotoro mharidzo kurema 410 makirogiramu ari zvidimbu 25 mm. The Drum iri zvayaitenderera paguyo kwemaminitsi 15 pa 10 Zvak / min. The zvichiguma kuparadzwa duku mashekeri chemubhotoro kuwira kuburikidza makwanza pakati pematanda. Simba paakati ndiye vazhinji chemubhotoro asara mukati dhiramu. Rimwezve chinhu ndiyo uwandu 10-0 mm hacho podbarabannom chigadzirwa. ruzivo Long-izwi yaratidza kuti chakaipa nokushanda Nokufema muvira zvinogona chemubhotoro, achipa vamwe dhiramu haisi makirogiramu asingasviki 300. The yakanakisisa akasiyana vari 340-350 makirogiramu Drum mharidzo. Similar nzira yokuedzwa jira rokuwedzera majoini inoshandiswa munyika dzakawanda, zvisinei, kuti Drum saizi, uremu mharidzo, nhamba nokumukirana akasiyana. Izvi zvakaguma nokusava comparability kuti zviratidzo zviri chemubhotoro simba uye waivako panguva yavo kwebhosvo yamavira. Saka, muna 1963 Soviet Sundgren akatsanangura nzira chikatsiviwa yemarudzi nzira dzokuziva simba chemubhotoro duku yakavharwa Drum dhayamita uye 1,000 mm pakureba (GOST 8929-65). On yomukati pose dhiramu 4 vari welded mumabhuraketi 100 mm. Kuedza chemubhotoro mutariri hombe nzwisa 60 mm mune mari kg 150, riri muzvikamu 3 zvikamu kurema 50 makirogiramu. The Drum akapiwa nomumwe wemigove izvi (makirogiramu 50) uye vaite kuti tenderera ari kumhanya 25 Zvak / Maminitsi nokuda 4 kwemaminitsi. Mharidzo yacho raizobviswa uparadzire nomusero pamwe kumativi mumwena dhayamita 40 mm uye 10 mm. Ichazivikanwa goho simba chemubhotoro chakapatsanurwa 40 mm (edza M40), uye ayo abradability - goho chakapatsanurwa 10-0 mm (M10 chazvo) ari chikamu uremu dzokuenzanisira. HIV mienzaniso miviri. Kana musiyano kunoguma tichitarisa M40 uye vanopfuura 3% tichitarisa anopfuura 1% M10 rechitatu bvunzo mharidzo. Kwokupedzisira mugumisiro kunotemwa sezvo svomhu avhareji. The kumusoro ari M40 uye M10 pazasi, akasimba ari chemubhotoro. Mumakore achangopfuura, panguva dzakawanda mafekitari chemubhotoro simba bvunzo zvakafanana (diki) dhiramu (GOST 5953-72), panguva imwe chete, nokuti kudhanilodha uye kutenderera, asi tora bvunzo chemubhotoro zviyo saizi 25 mm. Simba indekisi kuti chemubhotoro goho riri 25 mm chakapatsanurwa (M25) uye abradability - M10. Zvichakadaro ukoshi pamusoro zviratidzi idzi chemubhotoro simba, panguva USSR 1985 South miti zvakasiyana mukati zvinotevera neeSultan: M25 - kubva 70,7 kusvika 88,9%; M10 - kubva 6.3 kusvika 11.3%, uye mafekitari yeRussia uye Kazakhstan: M40 - kubva 57,8 kusvika 75,1%; M25 - kubva 83,7 kusvika 87,6% uye M10 - kubva 6,5 kusvika 10.0%. Also akataura nzira nokuda kuziva simba Nokufema muvira chemubhotoro zvinoshandiswa uye nevamwe. A zvakaipira izvi bvunzo nzira chemubhotoro simba muchando mamiriro iri yokuti havagoni kufungidzira simba raro panguva yakakwirira tembiricha uko chemubhotoro iri neshungu iri kwebhosvo muvira. kuedza kumisa nzira nokuda Pakusarudza chafariz kutsiga chemubhotoro. chemubhotoro simba kunobva mari uye chimiro makatsemuka mu akakora ayo zvakasimba. Kuparadzwa kunoitika kuburikidza mitswe zvidimbu, anoisa dzomunyika atinosangana yomuka panguva coking. Research akagadza kuti kuchinja PARTICIPLE saizi kuparadzira chemubhotoro hakusi Proportional kune pakakuvara simba, tanga nokukurumidza akapwanyika chemubhotoro, uwandu fines inowedzera zvinoshamisa uye zvinoderedza nehasha huru, ipapo kusabatana DZEMUNHU DZINODZORA. Zvakazoitwa ikure kutsemuka kunotungamirira kuchitendero chemubhotoro abrasion, sezvo Kupwanywa yose Piece chakaoma. Izvi akabvumira kuti vaongorore chemubhotoro simba akagadzikana nesefa sezvamunoita, vakawana mushure Implementation pamusoro makatsemuka zvose uye zvemukati mupfungwa. Yamunobvisira chemubhotoro nemhepo muchoto kubudikidza tuyere dzakaratidza kuti ayo sezvamunoita unoenderana anenge kuti nesefa ari kugadzikana sezvamunoita. Zvinozivikanwa kuti gasi permeability rejira rokuwedzera majoini nechamunosunungura lumpy zvinhu zviri nani pamwe nokuwedzera homogeneity waro saizi zvidimbu. Kuti uvandudze zvakafanana pakati chemubhotoro saizi kuwana optimum saizi akakora kuti Nokufema yamavira (25-40 mm), unoedza kwerubwinyo rwakagara rwuripo kudzikamisa wayo chinovhara sezvamunoita kuburikidza pasi kuti imwe mari zvokuimba kushushikana, uchiteverwa classifying kwaizoita fines. Izvi kuchaderedza kumwe Kuipa chemubhotoro nemavhinga kuti aumbe ari Nokufema muvira fines uye kuvandudza gasi permeability kupomerwa kwayo mukuru-tembiricha zvikamu.
