1. Lus Txhais ntawm qhov chaw nres nkoj cov ntawv cog lus, vim hais tias lawv tau thov rau kev tswj xyuas thiab kev tswj siab nrog rau cov cua nkag. Li ntawd, peb hu ua cov ntsiab lus xeem. Cov ntsiab lus xeem muaj nyob rau hauv cov hwj huam packs, valve blocks, hydraulic fais fab tuag, hydraulic thooj voos kheej kheej, machinery hnyav thiab siv qhov chaw machinery, lub ntiaj teb tsiv machine, truck, hydraulic kuaj rigs, thiab lwm yam
2. Qhov zoo ntawm kev sib tw kev sib txuas yog - nrog lwm qhov - kev sib txuas ntawm cov qib siab, qhov kev sib txuas tau yooj yim rau kev tswj thiab kev hloov khoom siv, cov ntaub ntawv pov thawj cov kev twb kev txuas thiab kev ruaj ntseg kev ruaj ntseg ntawm lub hau hlau. Daim ntawv spectrum comprises
A) los ntshav (xws li txhauv dej thiab lwm yam khoom ua hydraulic)
B) txhaws (piv txwv li cov roj kav dej thiab lwm cov khoom txuas nrog roj)
C) sampling (xws li kev kuaj hauv lub raj tshuaj ntsuam tom qab kuaj tshuaj)
D) nyeem ntawv siab (xws li kev qhia txog cov ntaub ntawv ceev).
3. Cov Qauv Tshawb Fawb Txog Cov Xeem: Raws li BS ISO 15171-2-2016 Cov Hoob Nkag Ua Rau Cov Kuaj Sib Ntsig Nrog Kev Tshawb Pom Tiav M16x2 kawg uas yuav raug txuas nrog lub siab tsis siv cov cuab yeej rau siab tshaj 10 MPa (400 bar) muab qhov kev kawm xaus:
ISO 6149-2 - M14 × 1.5;
ISO 9974-2 - M14 × 1.5;
ISO 1179-2 - G 1/4;
ISO 11926-2 - 7 / 16-20 UNF.
M16 × 2 threads yoog rau ISO 724, kam rau siab qib 6g rau sab nraud thiab 6H rau sab hauv xov raws li ISO 965-1.
4. Qhov kev sim ntawm txoj kev xeem yuav taw rau qhov kawg: 1 yog lub hau kev xaiv ntawm qhov kev txiav txim siab ntawm lub khw, 2 yog tus tsim ntawm qhov kev txiav txim siab ntawm lub khw, 3 yog kev tshawb nrhiav kev sib txuas, 4 yog xaiv tus qauv, 5 yog kev xauv co ntawm qhov kev txiav txim siab ntawm chaw tsim tshuaj paus.
5. Diagnostic coupling nrog ntau qhov chaw sealing:
Diagnostic coupling nrog ib tug sab nraud kawg FM 14x1,5 raws li ISO 6149-2 O-ring foob
Diagnostic coupling nrog ib tug kawm tiav EM 14x1,5 raws li ISO 9974-2 Elastomeric foob
Diagnostic coupling nrog ib tug kawm tiav kawg ISO 1179-2, G1 / 4 Elastomeric foob
Diagnostic coupling nrog ib tug kawm tiav kawg ISO 11926-2-7 / 16-20 UNF O-ring foob
6. Cov Khoom: Cov Hlau Hlau: Cov Hlau, Cov Hlau Tsis Muaj Raws li qhov thov 316L, 304 thiab lwm yam. Seal: NBR (-20 ° C to +100 ° C); FKM (-20 ° C to +200 ° C); EPDM (-40 ° C to +150 ° C) Hose: Polyamide (-35 ° C to +100 ° C)
7. Finish yog Zinc nickel, pob tshab, CrVI dawb.
Cim npe nrov: hydraulic kuaj taw tes fittings, Tuam Tshoj, manufacturers, lwm tus neeg, kev cai, tooj dag, swagelok, Parker, Stauff, Brennan, stainless hlau
