1. Core Product Overview
Qhov no yog lub diesel-powered kawg-suction centrifugal twj, tsim los txhim khu kev qha, cav-tsav dej hloov mus rau hauv off- daim phiaj lossis daim ntawv thov mobile. Nws koom ua ke ib qho hnyav - lub luag haujlwm cam khwb cia hlau twj tso kua mis nrog lub cav diesel uas muaj pov thawj- tsis tas yuav muaj hluav taws xob.
Siv nyob rau hauv kev tsim kho dewatering, ua liaj ua teb irrigation, dej nyab tswj, mine drainage, thiab lub nroog cov lus teb thaum muaj xwm txheej ceev uas tsis muaj fais fab mov.
Tsis yog hloov hluav taws xob twj tso kua mis retrofitted nrog ib txoj siv tsav. Qhov no yog lub hom phiaj -ua, ncaj qha-coupled diesel twj tso kua mis engineered rau kev siv teb tsis tu ncua nyob rau hauv cov mob hnyav.
2. Cov ntsiab lus tseem ceeb tawg
2.1 Pump Head – Xaus -Suction Centrifugal Design
Khoom siv: Cam khwb cia hlau lub cev, bronze impeller (tus qauv), NBR (nitrile) mechanical seal.
Hom Tsim: Ib qho -theem, overhung impeller, axial inlet / radial qhov hluav taws xob.
Tus kheej-Priming Capability: Txog li 7 meters qhuav nqa (nyob ntawm qhov loj thiab qhov kev sib khi).
Max Suction Lift: 7-8 m (nyob rau hauv zoo tagnrho tej yam kev mob: dej huv, kaw suction kab, tsis muaj to).
Kev Qhia Tawm Tawm: Sab saum toj tso tawm, kab rov tav lub qhov hluav taws xob- ua kom yooj yim rau cov kav dej.
Chaw Txuas Txuas: ANSI / ASME B16.1 Chav Kawm 125 flanges (tus qauv), xaiv tau BSP / NPT xov ntawm cov qauv me.
Vim li cas qhov no tseem ceeb:Lub casing nruj tuav lub siab siab; bronze impeller tiv thaiv corrosion los ntawm me ntsis abrasive los yog ntxhia- dej nplua nuj. Mechanical foob kav ntev dua li cov qog yog khaws cia kom zoo.
2.2 Diesel Cav - Muaj Qib Muaj Zog
Cav Hom Siv: Yuchai, Changchai, Lombardini, Kubota (model-nyob ntawm).
Cua txias: Cua-cooled (me me<15 HP), water-cooled (larger units ≥15 HP).
Roj Tank: Integrated 8-20L steel tank nrog lim, kaw -off valve, thiab pom gauge.
Txoj kev pib: Recoil (rope start) standard; hluav taws xob pib xaiv nrog 12V roj teeb khoom siv.
Tswv xeev: Hom centrifugal txhua yam - tswj RPM tsis tu ncua raws li qhov hloov pauv hloov.
Rated Ceev: 1800-3600 rpm (nrog rau lub twj tso kua mis ntawm rubey piv lossis sib txuas ncaj qha).
Field Note:Cua-cov cav txias yog sib dua thiab yooj yim dua tab sis xav tau ntxoov ntxoo nyob rau hauv lub hnub ncaj qha. Dej- cov ntawv txias txias ua haujlwm ntsiag to thiab txhawb nqa kev thauj khoom ntev dua.
2.3 Coupling System – Direct Drive vs. Siv Tsav
Ob configurations muaj:
| Hom | Nws ua haujlwm li cas | Pros | Cons |
|---|---|---|---|
| Direct Coupled | Lub twj tso kua mis txuas ncaj qha mus rau lub cav crankshaft ntawm kev sib txuas yooj yim | Compact, tsis muaj slippage, tsis tu ncua | Tsawg yoog raws hauv kev nrawm nrawm; alignment tseem ceeb |
| Belt Tsav | V-siv + pulleys txuas lub cav rau lub twj tso kua mis | Adjustable txaus / siab ntawm kev hloov pauv hloov; absorbs poob siab loads | Txoj siv tawv hnav, yuav tsum tau kuaj xyuas nruj, hloov qee zaus |
Cov neeg siv khoom feem ntau xaiv txoj siv tawv rau kev siv ntau yam -tshwj xeeb tshaj yog thaum siv cov dej qias neeg tsis tu ncua lossis sib txawv ntawm lub taub hau.
3. Hydraulic Performance Range (los ntawm Qauv Loj)
| Qauv | Lub impeller Dia (mm) | Max ntws (m³ / h) | Max taub hau (m) | Hom Siv Case |
|---|---|---|---|---|
| 4" (100 hli) | 220–260 | 120 | 45 | Ua liaj ua teb me me, dej nyab hauv qab daus, qhov chaw dewatering |
| 5" (125mm) | 260–300 | 180 | 50 | Medium irrigation, dej nkag, chaw txua txiag zeb pits |
| 6" (150mm) | 300–350 | 280 | 55 | Cov qoob loo loj, kev pab dej nyab ib ntus, qhib cov dej ntws tawm |
| 8" (200mm) | 380–420 | 500 | 60 | Kev kub ntxhov hauv nroog, mine sumps, industrial runoff |
Tag nrho cov kev ua tau zoo raws li cov dej huv hauv hiav txwv. Derate ~ 10-15% rau txhua 1,000m qhov siab nce.
4. Dab tsi Nws tuaj yeem ua tau - Cov dej txwv
Hom kua: Ntxuav rau cov dej qias neeg me ntsis (khoom txog li 5-10mm passable).
No sand slurry service. Sand content >0.5% txo qis impeller thiab foob lub neej.
pH Ntau: 6-9 tau. Zam cov dej khib nyiab los yog alkaline yam tsis tau kho qhov chaw ntub dej.
Max Dej Kub: 80℃(rau cov ntsaws ruaj ruaj thiab gaskets txheem). Kev kub siab dua yuav tsum muaj Viton cov ntsaws ruaj ruaj thiab cov kabmob tshwj xeeb.
Tsis txhob khiav qhuav rau ntau tshaj 1-2 feeb. Qhuav khiav hlawv tawm mechanical seals sai.
5. Ncej & Mounting – Tsim kom kawg
Baseplate: Heavy- ntsuas carbon steel channel ncej, hmoov-coated anti- xeb tiav.
Kev vibration Damping: Roj hmab mounts ntawm lub cav / twj tso kua mis thiab lub hauv paus txo kev qaug zog.
Lifting Points: Forklift slots + top lifting lugs (ntawm 6 "thiab 8" qauv).
Optional Trailer Kit: Towable thav duab nrog lub log, jacks, teeb pom kev zoo cables -npaj rau qhov chaw ua haujlwm.
Kev tawm tswv yim tawm tswv yim: Cov neeg siv khoom siv cov khoom siv trailer qhia sai dua thaum muaj xwm txheej dej nyab.
