Mokhoa oa ho Leka BROOKFIELD RVT

Brookfield RVT (Rotational Viscometer) ke sesebelisoa se sebelisoang hangata ho lekanya ho hlaka ha maro, ho kenyeletsoa lisebelisoa tse fapaneng tse sebelisoang liindastering tse kang lijo, meriana, litlolo le kaho. Mona ke kakaretso ea mokhoa oa tlhahlobo o sebelisang Brookfield RVT:

Thepa le Lisebelisoa:

1. Brookfield RVT Viscometer: Sesebelisoa sena se na le spindle e potolohang e qoelisoang ka har'a mokelikeli oa sampole, o lekanyang torque e hlokahalang ho potoloha spindle ka lebelo le sa khaotseng.
2. Li-spindles: Mefuta e fapaneng ea li-spindle e fumaneha bakeng sa ho amohela mefuta e mengata ea li-viscosity.
3. Mehlala ea Lijana: Lijana kapa likomiki tse tla tšoara mokelikeli oa sampole nakong ea tlhahlobo.

Mokhoa:

1. Tokisetso ea Mohlala:
   • Netefatsa hore sampole e mochesong o lakatsehang mme e kopane hantle ho netefatsa ho ts'oana.
   • Tlatsa setshelo sa mohlala ho ea boemong bo loketseng, ho netefatsa hore spindle e tla qoelisoa ka ho feletseng ka sampuli nakong ea tlhahlobo.
2. Calibration:
   • Pele u etsa liteko, lekanya viscometer ea Brookfield RVT ho latela litaelo tsa moetsi.
   • Netefatsa hore sesebelisoa se lekantsoe hantle ho netefatsa litekanyo tse nepahetseng tsa viscosity.
3. Tlhophiso:
   • Hokela spindle e loketseng ho viscometer, u nahanne ka lintlha tse joalo ka mofuta oa viscosity le molumo oa sampole.
   • Fetola litlhophiso tsa viscometer, ho kenyelletsa lebelo le li-unit tsa tekanyo, ho latela litlhoko tsa tlhahlobo.
4. Tekanyo:
   • Theola seluloana ka har'a seela sa sampole ho fihlela se qoelisoa ka botlalo, ho netefatsa hore ha ho na lipululana tsa moea tse qabeletsoeng ho pota-pota.
   • Qala ho potoloha ha spindle ka lebelo le boletsoeng (hangata ka liphetohelo ka motsotso, rpm).
   • Lumella spindle ho potoloha nako e lekaneng ho fihlela 'malo o tsitsitseng oa viscosity. Nako e ka fapana ho latela mofuta oa mohlala le viscosity.
5. Lintlha tsa ho Rekota:
   • Rekota lipalo tsa viscosity tse bontšitsoeng ho viscometer hang ha ho potoloha ha spindle ho tsitsa.
   • Pheta mokhoa oa ho lekanya ha ho hlokahala, ho lokisa liparamente kamoo ho hlokahalang bakeng sa liphetho tse nepahetseng le tse ka hlahisoang hape.
6. Tlhoekiso le Tlhokomelo:
   • Ka mor'a ho etsa tlhahlobo, tlosa setshelo sa mohlala 'me u hloekise spindle le likarolo tse ling tse ileng tsa kopana le sampuli.
   • Latela mekhoa e nepahetseng ea tlhokomelo bakeng sa viscometer ea Brookfield RVT ho netefatsa hore e tsoela pele ho nepahala le ho tšepahala.

Tlhahlobo ea Lintlha:

• Hang ha litekanyo tsa viscosity li fumaneha, sekaseka lintlha kamoo ho hlokahalang bakeng sa taolo ea boleng, ho ntlafatsa ts'ebetso, kapa merero ea ntlafatso ea sehlahisoa.
• Bapisa boleng ba viscosity ho lisampole tse fapaneng kapa lihlopha ho beha leihlo ho ts'oana le ho bona phapang efe kapa efe kapa mefokolo.

Qetello:

Brookfield RVT viscometer ke sesebelisoa sa bohlokoa sa ho lekanya viscosity ka maro le lisebelisoa tse fapaneng. Ka ho latela mokhoa o nepahetseng oa tlhahlobo o boletsoeng ka holimo, basebelisi ba ka fumana litekanyo tse nepahetseng le tse tšepahalang tsa viscosity bakeng sa netefatso ea boleng le taolo ea ts'ebetso liindasteri tse fapaneng.
