Zingaphi Iintlobo zePaki yeMveliso

Iindidi zokupakisha zahlukile ngokwemigangatho eyahlukeneyo. Eli nqaku liza kwazisa ngokomgangatho walo ohlukeneyo. Kuya kukunceda ukhethe eyona nto ingcono yokupakisha ioli kunye negesi.

1. Ngokutsho kokusetyenziswa kompakishi

1) Umpakishi we-oyile kakuhle

Abapakishi abanjalo bangohlulwa ngokweepaki ezisusa i-oyile (ezifana nokuvalwa kwamanzi e-stratified, ifosholo, ukuhlolwa, iipaki zokuvavanya i-oyile), iipaki zokuqhekeka kwe-asidi, kunye nokubuyiswa kobushushu kwimithombo yeoli enzima. Umpakisheli we-Layer, i-thermal cycle packer yemithombo yeoli ephezulu, njl.

2) Isixhobo sokupakisha semithombo yamanzi yokutofa

Abapakishi abanjalo banokwahlulahlulwa kwiipakethe ezigcwele amanzi, iidridi zerhasi ezicwangcisiweyo (kubandakanywa ne-steam drive) abapakishi, abapakishi be-polymer flood, kunye nokunye okunjalo.

2. Ngokwendlela yofakelo

(1) Umpakishi wokutyibilika omnye: Umpakisho wokutyibilika omelana kuphela nokwahlukana koxinzelelo kwicala elinye.

(2) Umpakishi wokutyibilika kabini: usete ukumelana noxinzelelo oluphezulu nolusezantsi lwe-bidirectional.

(3) I-packer ye-slip iyonke: inokumelana nokwahlukana koxinzelelo phakathi kwephezulu kunye nezantsi.

3. Ngokobukhulu

Ubukhulu bedayamitha yangaphandle yomzimba wentsimbi inxulumene nedayamitha yangaphakathi yecasing.

I-5in ipakethe yequla: ubuninzi bangaphandle bomzimba wentsimbi yi-99-102mm;

I-5 1/2in ipakethe kakuhle: ubuninzi bobukhulu bangaphandle bomzimba wensimbi yi-113-116mm;

I-6 5/8in ipakethe yequla: ubuninzi bobukhulu bangaphandle bomzimba wentsimbi yi-136-140mm;

I-7 kwi-packer yomthombo: ubuninzi bobukhulu bangaphandle bomzimba wensimbi yi-148-152mm;

I-9 5/8 kwi-packer kakuhle: ubuninzi bobukhulu bangaphandle bomzimba wensimbi yi-190-208mm;

Vula i-packer yomngxuma: Ubuninzi bangaphandle bomzimba wentsimbi yi-140mm.

4. Ngokutsho kobushushu bokusebenza

(1) Umpakisho oqhelekileyo: ubushushu obusebenzayo 120 °C.

(2) Ipakethe yokupakisha iThermal: ubushushu obusebenzayo yi-350 °C.

5. Ngokomgaqo wokusebenza kwetywina

Olu lwahlulo luhlelwa ngendlela yokuba izitywini zokupakisha zitywinwe.

(1) Uhlobo lokuzitywina: umpakishi ofezekisa ukutywinwa ngedayimitha yangaphandle yelungu lokupakisha elitywiniweyo (njengesilinda yerabha yerabha) (idayamitha engaphandle yekomityi) kunye nokuphazamiseka phakathi kwedayamitha engaphakathi yebhokisi kunye noxinzelelo lokusebenza. umahluko.

(2) Uhlobo loxinzelelo: Umpakishi ofezekisa ukutywinwa nge-axial force ecinezela i-diameter yangaphandle yelungu lokupakisha isitywina (njengesilinda yerabha) ukuba ibe nkulu (ifanele udonga lwangaphakathi lomkhono).

(3) Ukwandisa uhlobo: Umpakisheli osebenza kumqolo ongaphakathi welungu lokupakisha ngamandla eradial ukwandisa i-diameter yangaphandle yompakisheli wokutywina ukufezekisa ukutywinwa, kwaye ukwabizwa ngokuba ngumpakisho woxinzelelo olwahlukileyo ngeentsuku zeveki.
