Ishubhu eliyisikweleuhlobo lwezinto ezisetshenziswa kakhulu embonini yokwakha yezimboni, ezinesidingo esikhulu. Kunemikhiqizo eminingi yeshubhu yesikwele emakethe, futhi ikhwalithi ayilingani. Kufanele kunakwe indlela yokukhetha lapho ukhetha:
1. Bheka usayizi
Ithuluzi lokulinganisa i-vernier clamp lingasetshenziswa ukukala nje ukuthi usayizi wangempela ucishe ube yinye incazelo noma mncane kunosayizi ophawuliwe. Ngokuvamile, akukho mehluko omkhulu phakathi kwamapayipi amahle esikwele; Ngaphezu kwalokho, kufanele kuqashelwe ukuthi amanye amapayipi esikwele asezingeni eliphansi azokhohlisa umbono wabantu ngokuphula umlomo. Ngakho-ke, ubuso bokugcina bombhobho wensimbi kufanele bube yi-oval eyisicaba, kanti ubuso bokugcina bezinto ezivamile kufanele bube yindilinga ngokuyisisekelo.
2. Bheka ukusebenza
Ishubhu lesikwele linezakhiwo ezithile zokuthamba nokucindezela, ngakho-ke singazicabangela nalezi zici lapho sikhetha ishubhu lesikwele: amandla okuthamba ukusebenza kweshubhuipayipi lesikweleisisekelo, futhi uma amandla okudonseka emakhulu kusho ukuthi ukusebenza kwepayipi lesikwele kungcono; Kuzocatshangelwa kabanzi nokumelana nokucindezelwa kanye nokumelana nokugoba.
3. Bheka ikhwalithi yobuso
Ikhwalithi engaphezulu ye-inferioramashubhu asikweleayinhle ngenxa yokugingqika ngezinto zokusetshenziswa ezingafanele, futhi ivame ukuba neziphambeko ezifana nokukhuhla futhi inomuzwa oqinile. Ezinye izigayo zensimbi ezincane zinombala obomvu ngenxa yokushisa okwanele kanye nesivinini sokugingqika; Ikhwalithi yeshubhu yesikwele yekhwalithi ephezulu iyafaneleka, ngaphandle kweziphambeko ezisobala, futhi umbala umhlophe futhi ukhanya.
4. Bheka iphakheji
Iningi lamapayipi ajwayelekile angunxande ayisikwele apakishwa ngamaqoqo amakhulu uma elethwa efektri. Amapuleti ensimbi ahambisana nezinto zangempela alengiswe ezinqwabeni zensimbi, okubonisa umenzi, uhlobo lwensimbi, inombolo yebhetshi, imininingwane kanye nekhodi yokuhlola, njll.; Kufanele kuqashelwe ngokukhethekile imikhiqizo yamashubhu angunxande enezinqwabe ezincane (cishe izinqwabe eziyishumi) noma ngobuningi, ngaphandle kwamalebula ensimbi kanye nezitifiketi zokuqinisekisa ikhwalithi.
