Namuhla, izihloli zokuqina ze-Leeb eziphathwayo zisetshenziswa kakhulu ekuhlolweni kwezindawo eziningi zokusebenza. Ake ngethule ulwazi oluthile mayelana nabahloli bokuqina be-Leeb.
Ukuhlolwa kokuqina kwe-Leeb kuyindlela entsha yokuhlola ubulukhuni eyaphakanyiswa uDkt. Leeb wase-Swiss ngo-1978.
Isimiso sokuhlolwa kokuqina kwe-Leeb: Umzimba onomthelela onesisindo esithile uyathinteka endaweni yesampula ngaphansi kwamandla athile okuhlola, futhi isivinini somthelela nesivinini sokubuyela emuva somzimba womthelela ongu-1mm ukusuka endaweni yesampula kuyalinganiswa. Kusetshenziswa isimiso sikazibuthe kagesi, umthelela obangiwe kanye nevelu yobulukhuni be-Leeb ibalwa kusukela kusilinganiso sesivinini sokuphindaphinda, okuyindlela yokuhlola enamandla.

Ngakho-ke hlobo luni locezu lokusebenza olufanele umhloli we-Leeb?
Umhloli wokuqina we-Leeb uyisihloli sokuqina sokuqina esingaguqula ngokukhululekile i-Rockwell, Brinell, Vickers, ne-Shore hardness scale. Nokho, inezidingo ze-workpiece. Akuwona wonke ama-workpiece angasebenzisa isikali sokuqina sika-Leeb. Isilinganiso somhloli wokuqina ukuze singene esikhundleni sesihloli sokuqina sokuqina kwebhentshi. (Lokhu kune-interface yokuguqula ye-Leeb hardness test)
Ngokusekelwe kumgomo wokulinganisa we-Leeb hardness tester nokuphatheka kwayo, ifaneleka kakhulu (kodwa ayikhawulelwe) ekukalweni kwezinto zokusebenza ezilandelayo:
Izingxenye ezingomshini noma ezihlanganiswe unomphela ezifakiwe futhi ezingenakususwa
Izinto zokusebenza ezinesikhala esincane kakhulu sokuhlola njengezimbotshana zesikhunta (udinga ukunaka usayizi wesikhala lapho uthenga)
Ama-workpiece amakhulu adinga ukuhlolwa ngokushesha nangeqoqo
Ukuhlaziywa kokwehluleka kwemikhumbi yokucindezela, ama-generator ama-turbine nezinye izinto zokusebenza.
Ukulawulwa kokuqina kwemigqa yokukhiqiza yama-bearings nezinye izingxenye
Izingxenye ezingomshini noma ezihlanganiswe unomphela ezifakiwe futhi azikwazi ukuhlakazwa
Izinto zokusebenza ezinesikhala esincane kakhulu sokuhlola njengezimbotshana zesikhunta (udinga ukunaka usayizi wesikhala lapho uthenga)
Ama-workpiece amakhulu adinga ukuhlolwa ngokushesha nangeqoqo
Ukuhlaziywa kokwehluleka kwemikhumbi yokucindezela, ama-generator ama-turbine nezinye izinto zokusebenza
Ukulawulwa kokuqina kwemigqa yokukhiqiza yama-bearings nezinye izingxenye
Ukuhlolwa okuphelele kwezinto ezibonakalayo kanye nokuhlukaniswa okusheshayo kwempahla yensimbi
Ukulawulwa kwekhwalithi ngesikhathi sokukhiqizwa kwama-workpieces aphathwe ukushisa
Abahloli bokuqina be-Leeb abavame ukusetshenziswa enkampanini yethu bahlanganisa okulandelayo:
Iphrinta ye-HLN110 uhlobo lwe-Leeb Hardness Tester
I-HL200 yombala wohlobo lwe-Leeb Hardness Tester
I-HL-150 Pen uhlobo lwe-Leeb Hardness Tester
Isikhathi sokuthumela: Sep-14-2023
