Ziziphi izinto ezinokuthi zichaphazele umgangatho wokulahla abavelisi bentsimbi?

Umgangatho we-castings unempembelelo enkulu kwisixhobo somatshini, njenge-impeller yeepompo ezahlukeneyo, ubukhulu bendawo yangaphakathi ye-hydraulic parts, i-shell shell ecutshungulwayo, ukuchaneka komgca wokubumba kunye nokugqithisa komhlaba, njl. Iingxaki ziya kuchaphazela ngokuthe ngqo ukusebenza kakuhle kweepompo kunye neenkqubo ze-hydraulic, kunye nokuphuhliswa kokusetyenziswa kwamandla kunye ne-cavitation.Ezi ngxaki zisenkulu ngokwentelekiso, njengentloko yesilinda, ibhloko yesilinda, i-cylinder liner, kunye nokuphuma kweenjini zokutsha zangaphakathi.Ukuba amandla kunye nokupholisa kunye nokufudumeza iimpawu zokuphosa ezifana nemibhobho yomoya ayilungile, iya kuchaphazela ngokuthe ngqo ubomi benkonzo ye-injini.

Ukongeza kwezi zikhankanywe ngasentla ngabavelisi bentsimbi, kukho izinto ezininzi ezinokuchaphazela umgangatho weentsimbi zensimbi.

1. Ukusebenza kwenkqubo, inkqubo yokusebenza kwenkqubo efanelekileyo kufuneka yenziwe kuqala xa ilungiswa, kwaye ngelo xesha, inqanaba lobugcisa labasebenzi kufuneka liphuculwe, ukwenzela ukuba inkqubo iphunyezwe ngokuchanekileyo.

2. Ngokubhekiselele kubugcisa bokuyila, ubugcisa bokuyila obulungileyo bunokuvelisa iimveliso ezilungileyo zokuphosa.Xa uyila, i-factory casting steel idinga ukugqiba ubungakanani kunye nemilo yokuphosa ngokweemeko zokusingqongileyo kunye nezinto eziphathekayo zetsimbi.Kwaye njalo, kufuneka kwakhona siqwalasele ingqiqo yoyilo ukusuka kwimiba yeempawu zenkqubo yokuphosa ukuphepha iziphene ezingeyomfuneko.

3. Ngobugcisa bokuphosa, i-factory casting metal inokukhetha indlela efanelekileyo kunye nendlela yokwenza i-core-making ngokwesakhiwo, ubukhulu, ubunzima kunye neemeko ezifunekayo zokuphosa, kwaye usete ubambo lokuphosa okanye intsimbi ebandayo, inkqubo yokugalela kunye nokuphosa. inkqubo ngokwezi.Riser njalo njalo.

4. Ngokubhekiselele kwizinto eziphathekayo, abavelisi kufuneka bahlawule ngokukodwa kumgangatho wezinto ezisetyenziselwa ukuphosa.Umgangatho wezinto ezisetyenziselwa ukuphosa kufuneka uhlangabezane nomgangatho, ngaphandle koko kuya kubangela iziphene ezifana ne-porosity, i-pinholes, i-sand sticking kunye nokufakwa kwe-slag kwi-castings, eya kuchaphazela ngokuthe ngqo i-castings.Umgangatho wokubonakala kunye nomgangatho wangaphakathi wentsimbi, ukuba unzulu, uya kubangela ukuba ukuphosa kukhutshwe ngokuthe ngqo.

Umgangatho weemveliso ikakhulu ubandakanya iintlobo ezintathu: umgangatho wembonakalo, umgangatho wangaphakathi kunye nomgangatho wokusetyenziswa:

1. Umgangatho wenkangeleko: ubukhulu becala ubhekisa kuburhabaxa bomphezulu, ukutenxa kobungakanani, ukutenxa kwimilo, iziphene zomaleko womphezulu kunye nokutenxa ubunzima, njl.njl., ezinokujongwa ngokuthe ngqo, zonke zingumgangatho wenkangeleko;

2. Umgangatho wangaphakathi: Ikakhulu ibhekisa kukwakheka kweekhemikhali, iipropathi zoomatshini kunye neempawu ezibonakalayo zokuphosa.Ngokubanzi, umgangatho wangaphakathi unokubonwa kuphela ngokufunyaniswa kokusilela.Ukufumanisa impazamo kunokubona ukuba kukho ukubandakanywa, imingxuma, ukuqhekeka, njl. ngaphakathi kokuphosa.isiphene;

3. Umgangatho wokusetyenziswa: ubukhulu becala ukuqina kokuphosa kwiindawo ezahlukeneyo, njengokunganyangeki, ukumelana nokugqwala, ukumelana nokudinwa, ukuchaneka, kunye ne-weldability.
