FAQ rau cov neeg yuav khoom
Q1: Dab tsi yog qhov siab tshaj plaws tso cai ntsug ntev rau kev khiav hauj lwm saw? Nws puas yuav cuam tshuam rau lub zog ua haujlwm?
- A1:Standard chain lengths feem ntau yog 3 meters los yog 6 meters, nrog ntev kev cai ntev muaj nyob rau hauv kev thov. Raws li cov saw lengthens, kev sib txhuam nce me ntsis. Txawm li cas los xij, los ntawm kev txhim kho sprocket bearing tsim, kev ua haujlwm ib txwm ua los ntawm ib tus neeg tuaj yeem ua tau txawm tias qhov ntev tshaj plaws. Rau ntxiv - ntev chains, lubrication tsis tu ncua yog pom zoo kom ua haujlwm zoo.
Q2: Lub valve puas tuaj yeem khaws cia qee qhov qhib rau kev tswj hwm ntws?
- A2: Tsis pom zoo.Chain Operated Gate Valve yog tsim los rau kev sib cais nyob rau hauv qhov qhib siab lossis kaw tag nrho. Nws lub rooj vag qauv muaj qhov cuam tshuam rau cov kua dej yaig thiab kev co thaum qhib ib nrab, ua rau lub ntsej muag tsis pom kev puas tsuaj thiab qia hnav. Dedicated tswj li qub yuav tsum tau siv rau kev khiav dej num.
Chain Operated Gate Valve Maintenance Recommendations
- Kev tshuaj xyuas tsis tu ncua thiab lubrication:Nws raug nquahu kom pom qhov muag tshuaj xyuas cov saw thiab sprocket peb lub hlis twg, tshem tawm cov khib nyiab. Siv cov qauv tsim nyog -lub hom phiaj roj rau lub qhov rooj sprocket thiab cov hlua txuas txhua rau lub hlis kom txo tau hnav thiab ua haujlwm yooj yim. Rausaw ua haujlwm rooj vag li qub rau cov kav dej hauv av, xyuam xim tshwj xeeb rau kev tshuaj xyuas tom qab lub caij los nag lossis kev ua haujlwm tu.
- Ncej -Kev Tswj Xyuas Kev Ua Haujlwm:Tom qab ua tiav tag nrho qhib lossis kaw, sim thim rov qab cov saw log me ntsis los ntawm ib nrab tig. Qhov no pab tso tawm cov kev ntxhov siab nyob rau hauv cov qia threads thiab lub rooj vag qhia qhov, tiv thaiv ib feem ntawm deformation los yog txeeb vim lub sij hawm ntev unidirectional quab yuam, yog li ncua kev pab cuam lub neej.
