Koj tuaj yeem xa mus rau cov ntsiab lus hauv qab no:
1) Kev kuaj pom pom:
A. Txhua qhov chaw ntawm calabash yuav tsum tau tsim kom zoo, tsis muaj caws pliav, burrs thiab lwm yam tsis xws luag uas cuam tshuam rau cov tsos zoo
B. Cov xwm txheej ntawm nqa saw ntawm qib hoist 3 tuj.
Cov hauv qab no yuav tsum tau muab tshem tawm:
(1) degree ntawm corrosion: nto ntawm cov saw yog pitted corrosion los yog flake tawm.
(2) hnav ntawm cov saw ntau tshaj 10% ntawm nominal txoj kab uas hla;
(3) deformation, tawg thiab kev puas tsuaj sab nraud;
(4) Pitch ntev hloov ntau dua 3%.
C. Hook condition.
Cov hauv qab no yuav tsum tau muab tshem tawm:
(1) Deformation los yog poob ntawm kev ruaj ntseg pin ntawm nuv;
(2) Lub nplhaib sib txuas ntawm tus nuv yog xeb thiab tsis tuaj yeem tig dawb (360 ° kev sib hloov);(3) Hook hnyav hnyav (ntau tshaj 10%) thiab nuv deformation (ntau tshaj 15% loj nce), torsion (ntau tshaj 10 °), tawg, mob lub kaum sab xis, corrosion, thiab warping.
D. Cov phau ntawv tuav lub zog yuav tsum tau nruab nrog cov saw hlau uas tsim nyog los pab txoj kev sib koom ua ke ntawm cov saw thiab sprocket, thiab xyuas kom cov saw yuav tsis poob tawm ntawm lub nplhaib sprocket zawj thaum lub zog hoist muab tso rau thiab co ntawm qhov xav tau.
2) Cov txheej txheem xeem:
A.Static load test: nyob rau hauv static load test, rub tus kov thiab toggle lub reversing claw, thiaj li hais tias tus nuv nce thiab nqis ib zaug, txhua lub mechanism yuav tsum khiav flexibly, tsis muaj jamming los yog xoob thiab nruj tshwm sim.Tshem tawm cov khoom siv clutch, rub cov saw ntawm tes yuav tsum yog lub teeb thiab hloov tau.
B.Dynamic load test: nyob rau hauv 1.5 zaug load test, cov nram qab no yuav tsum tau ua raws li:
(1) nqa saw thiab sprocket, nkoj nkoj, tes rub saw thiab tes sprocket meshing zoo;
(2) Cov iav kis tau tus mob yuav tsum du thiab tsis muaj qhov tshwm sim txawv txav;
(3) Tsis muaj qhov torsion thiab kink tshwm sim ntawm cov saw nqa hauv cov txheej txheem ntawm nqa thiab nqis;
(4) Tus kov yog ruaj khov, thiab txhais tes rub lub zog tsis muaj kev hloov pauv zoo;
(5) Lub nres nres yog txhim khu kev qha.
