Ts'ebetso ea li-cutters tsa PDC

Lipatlisiso le nts'etsopele ea li-cutters tsa PDC li ile tsa ntlafatsoa linaheng tse ngata ka bo-1970. Moemeli ke "stratapax" ke khamphani ea G.E, The "syndrill" ke k'hamphani ea DeBeers, le "Claw Cutter" ea Sandvik.

Ts'ebetso ea li-cutters tse kaholimo tsa PDC, ho sa tsotelehe hore na li hana ho apara, li na le tšusumetso e matla, kapa mocheso o tsitsitseng, kaofela li emela maemo a holimo a lefats'e ka nako eo.

Ts'ebetso ea PDC cutter e bua haholo ka matšoao a latelang:

1. Rear resistance (hape e tsejoa e le wear ratio),

2. Matla a khahlanong le tšusumetso (joule),

3. Ho tsitsisa mocheso

Kamora nako e telele ea liteko bakeng sa seha PDC, re ile ra fumana hore boemo ba li-cutters tsa PDC naheng ea rona bo ka tlase:

Bohareng ba 1990 ho 2003: ho hanyetsa ho apara ke 8 ho 120,000 (10 ho 180,000 linaheng tse ling);

Tšusumetso e matla ke 200 ~ 400 j (ho ​​feta 400 j kantle ho naha).

Phetoho ea botsitso ba mocheso ke: ka mor'a ho sintering ho 750 ° C (tlas'a maemo a ho fokotsa), tekanyo ea Wear e bontšoa hore e nyoloha ka 5% ho ea ho 20% ho bahlahisi ba bang ba malapeng, 'me ho tiea ha tšusumetso ha ho na phetoho e kholo. Baetsi ba bang ba fokotsehile ka tekanyo ea ho apara le ho ba khahlanong le tšusumetso e thata.

Ho akaretsa, ho thatafala, ho se mamelle, ho tiea ha mocheso, le botsitso ba mocheso oa lihahi tsa PDC tsa naha ea rona li atametse 'me li fihlile boemong bo phahameng ba machaba, ho rala motheo oa ho tsoela pele ho cheka majoe a thata a mahareng ka lihahi tsa PDC.

Re bitsa PDC cutter ka boima bo phahameng, khanyetso e phahameng ea ho apara, ho ba le tšusumetso e matla, le botsitso bo phahameng ba mocheso oa li-PCC tse 'nè tse phahameng. Ho cheka ka li-cutters tsa boleng bo holimo tsa PDC ho tla tsamaisa nts'etsopele e felletseng ea merero ea ho cheka

Melemo ea ho cheka libopeho tsa mafika a bonolo ho isa ho a thata-thata, haholoholo mafika a thata, ka ho sebelisa mochini oa ho cheka o kopantsoeng ke:

1. Bokhoni ba ho silakanya mafika bo ntlafetse haholo

2. Ho sebetsa ka mokhoa o phahameng le ho khutsufatsa nako ea kaho

3. Khothaletsa nchafatso ea lisebelisoa tsa ho cheka.

4. Tšebeliso ea li-cutters tsa boleng bo phahameng ba PDC li khothalletsa phetoho ea sebopeho sa daemane le moralo oa li-parameter tsa hydraulic.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka ho le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
