Menene Injin Laka?

TheMotar Muhalli Mai Kyau (PDM), wanda kuma aka sani da"injin laka"wani muhimmin rami ne mai zurfikayan aikin hakowaana amfani da shi a ayyukan mai da iskar gas. Yana canza makamashin hydraulic daga ruwan haƙa (laka) zuwa juyawa na inji don tuƙa ɓangaren haƙa, wanda hakan ke sa ya zama dole don haƙa hanya, rijiyoyin kwance, da kuma bin diddigin gefe.

I. Tsarin da Ka'idar Aiki

1. Maɓallan Abubuwan Ciki

Bawul ɗin Kewaya: Yana ba da damar zagayawa cikin ruwa yayin tuntuɓewa don hana hauhawar matsin lamba.

Sashen Motoci: Na'urar wutar lantarki ta tsakiya, wacce ta ƙunshistator(bututu mai layi na elastomer) da kumana'urar juyawa(sukurorin ƙarfe mai siffar helical).

Haɗin gwiwa na Duniya: Yana canza motsin rotor mai ban mamaki zuwa juyawa mai ma'ana.

Shaft ɗin Tuƙi: Yana aika karfin juyi zuwa ga injin haƙa rami, wanda aka tallafa masa ta hanyar haɗa kayan haɗin bearing don nauyin axial/radial.

2.Ka'idar Aiki

Ruwan haƙa mai ƙarfi yana shiga cikin injin, yana tilasta wa rotor ya juya a cikin stator ɗin a cikin motsi na duniya (birgima + juyawa).

Ana canja wurin juyawar rotor ta hanyar haɗin gwiwa na duniya da shaft ɗin tuƙi zuwa ga ɓangaren haƙa.

Yawan kwarara (Q) idan aka kwatanta da RPM (N):

N=qQ×ηv;

Q: Yawan kwarara (L/s)

q: Gudun hijira a kowace juyin juya hali (L/rev)

ηv​: Ingancin girma (yawanci 80-90%)

II. Rarraba PDMs

1. Ta hanyar Zane

PDM mai lobe ɗaya (tsarin 1:2): Babban gudu, ƙarancin ƙarfin juyi (misali, don haƙa rami mai siriri).

PDM mai launuka da yawa (misali, tsarin 5:6): Ƙaramin gudu, ƙarfin juyi mai yawa (misali, ga manyan ragowa ko tauri).

2. Ta hanyar Aikace-aikacen

Daidaitaccen PDM: Ana amfani da shi a rijiyoyin tsaye ko masu sauƙi.

Bent Housing PDM: Yana da kusurwar lanƙwasa mai ɗorewa (misali, 1°, 1.5°, 2°) don sarrafa alkibla.

Injin turbine mai haɗaka-PDM: Yana haɗa babban RPM (turbine) tare da babban ƙarfin juyi (PDM).

III. Ma'aunin Aiki Masu Muhimmanci

IV. Zaɓa & Aikace-aikace

1. Sharuɗɗan Zaɓe

Taurin Tsarin: Tsarin tauri yana buƙatar PDMs masu lobe da yawa don ƙarfin juyi mai girma.

Hanyar Rijiya: Rijiyoyin da ke kan hanya suna buƙatar PDMs masu lanƙwasa.

Ruwan hakowa: Laka mai tushen mai yana buƙatar elastomers masu jure wa mai (misali, HNBR); Muhalli na H₂S suna buƙatar kayan aiki masu amfani da tsami.

2. Aikace-aikacen da Aka saba

Hakowa a kwance: Ana amfani da shi tare da tsarin MWD/LWD don daidaitaccen tuƙi.

Bin diddigin gefe da Ayyuka: Yana bayar da juyawa bayan fitowar kashin.

Rijiyoyi Masu Zurfi/Mai Zurfi: Yana buƙatar stators masu zafi mai yawa da kayan aiki masu ƙarfi.

V. Kurakurai da Kulawa da Aka Saba Yi

VI. Yanayin da ke tafe

1.PDM masu wayo: Na'urori masu auna firikwensin da aka haɗa don sa ido kan yanayin zafi/juriya/girgiza a ainihin lokaci.

2.Kayan Aiki na Ci gaba: Rotors masu rufi da nano, elastomers 200°C+.

3.Tsarin Haɗin Kai: Haɗakar PDM + turbine don hadaddun tsari.

Landrill na iya samar da nau'ikan injinan laka (PDMS) masu inganci mafi kyau.Idan kuna sha'awar su, don Allah ku tuntube mu. Za mu iya aiko muku da ƙarin bayani.
