Bahlahisi ba ho cheka liliba tsa metsi a pneumatic ba u joetsa mokhoa oa ho sebetsana le likarolo tse fapaneng tsa mobu tse kopaneng le lisebelisoa tsa ho cheka liliba tsa metsi.

Joaloka moetsi oa lisebelisoa tsa ho cheka liliba tsa pneumatic, rea utloisisa hore lisebelisoa tsa ho cheka liliba tsa pneumatic li lokela ho sebelisa mekhoa e fapaneng ha li kopana le likarolo tse fapaneng tsa jeoloji ts'ebetsong ea ho cheka ho fihlela litholoana tse ntle. Likarolo tse fapaneng tsa jeoloji le tsona li lokela ho kopana le tsona, joalo ka lesela la quicksand le gypsum layer. Hang ha ho kenella ha gypsum ho etsahala nakong ea ts'ebetso ea ho cheka seliba sa metsi a pneumatic, li-ion tsa calcium li ka tlosoa ka ho ea molora oa soda, ho tlosoa ha k'halsiamo le ho fokotsa viscosity. Ho sa le joalo, sesebelisoa se fokotsang viscosity se nang le k'halsiamo e matla e hanyetsanang le khalsiamo e ka sebelisoa ho laola ho fokotsa li-viscosity le ho etsa bofokoli ba ho fokotsa tahlehelo ea li-filters, anti-collapse agent le lisebelisoa tse ling.

I. Lera la Gypsum

Pele o cheka lesela la gypsum, mokelikeli oa ho cheka oa rig o etsoa esale pele ho fokotsa sekhahla se tiileng le viscosity, 'me ho ameha li-anti-gypsum agents (mohlala, soda ash, remover ea calcium, viscosity reducer, joalo-joalo). 'Me ho ea ka thepa ea kaho ea liliba tsa boahelani, moemeli oa phekolo bakeng sa ho phekola lera la gypsum o lokiselitsoe esale pele. Ntlafatsa boleng ba pH ba mokelikeli oa ho phunya oa mochini oa ho cheka seliba sa metsi, 'me u ntlafatse bokhoni ba mochini oa ho cheka seliba se senyenyane sa metsi ho thibela tšilafalo ea gypsum.

Ea bobeli, lera la lehlabathe le potlakileng

Ha ho cheka ka mokhoa oa ho cheka lehlabathe le potlakileng, hoa hlokahala ho ntlafatsa viscosity ea mokelikeli oa ho cheka le lihlahisoa tsa bentonite tsa metsi a seliba sa metsi a ho phunya, ao ka kakaretso a hlokehang ho ba ka holimo ho 10%. E le ho ntlafatsa ts'ebetso ea ho etsa lerako la metsi a ho phunya seliba sa metsi, ho senyeha ha lera la lehlabathe le potlakileng ho fokotseha ka mor'a ho fokotsa ka mokhoa o nepahetseng ho falla ha morero. Pele o qala ho cheka, karolo e tlameha ho koaloa ka seretse se teteaneng se nang le viscosity e kholo ho feta 80 ho etsa bonnete ba ho qala le ho emisa ha ho phunya, ho rema lifate tsa motlakase le ho kenya mochine o monyenyane oa ho phunya seliba sa metsi.

III. Lejoe la lehlabathe la quartz

Ha nako ea sandstone e le lejoe le thata haholo, ts'ebetsong ea ho phunya hangata e bonahala e lieha ho cheka tsoelo-pele. Ho ka 'na ha e-ba le lehlabathe la limithara tse peli ha u cheka mithara e le' ngoe, lisebelisoa tsa ho phunya li qhoma ka matla, li-slag cuttings tse ngata le liphoso tsa ho phunya. Kahoo ho hlokahala kutloisiso e qaqileng ea sebaka seo.

Metsi a hloekileng ha a na mafura a tšoanang le a seretse, ’me lithulusi tsa ho cheka lejoeng le thata li qhoma hoo lefika le pshatlehang ha lisebelisoa tsa ho cheka li qhomela holimo; metsi a hloekileng a na le thepa e kholo ea ho hlopha, 'me metsi a phallang ha a khone ho ntša majoe a maholo a ntseng a eketseha ho tsoa ka mokoting. Lithako tsa majoe tse kang lehlabathe li ile tsa ’na tsa phaphamala le ho teba ka mokoting. Haeba ho sebelisoa tube ea ho ntša phofo, ho ka chekoa mithara e le 'ngoe kapa tse peli tsa lehlabathe. Ho se tsotelle hanyenyane ho ka 'na ha epela boro,' me lehlabathe le lengata le ka baka mathata a mangata ha ho phunya lesoba.

Lejoe la lehlabathe nakong ea kopo le entsoe ka deposition mme ke lejoe le thata haholo. Metsi a manyane a pneumatic a ho cheka sekoti ha a cheka sekoti ha a teba haholo (303354200 m), ka hona ts'ebeliso e akaretsang ea ho cheka metsi a daemane, seretse se ikemetseng, hangata se bonts'oang butle butle, mitha e le 'ngoe ea litšoantšo tsa ho phunya e ka senola limithara tse peli. ea lehlabathe, cheka sesebelisoa qhoma tebileng, slag, chipped lefika ho feta, ho cheka hloleha ho patoa joalo-joalo.

Tharollo: Haeba ho cheka ka seretse ho se moruo, o ka fokotsa ketsahalo ea lehlabathe ka ho khaola palo ea li-rigs tse nyane tsa ho cheka hantle, o ka eketsa li-additives tsa nitro acid le alkali ka metsing ho bapala karolo ea li-vibration damping lubrication, kahoo hore u ka fokotsa palo ea li-rigs tse qhomang le lehlabathe, ebe u khomarela ho hloekisoa ha likoti tsa ho phunya likoti tsa metsi a pneumatic, 'me qetellong u rarolle bothata!
