Cov txheej txheem ntau lawm
Kev xaiv khoom
Lub boom lub tog raj kheej yog tsim los ntawm precision machining txheej txheem. Lub cylinder chim yog ua los ntawm Qib 20 lossis 45 seamless steel yeeb nkab, thaum lub piston pas nrig yog ua los ntawm 40Cr lossis 38CrMoAlA cov khoom.
01
Fatigue Resistance
Sab hauv phab ntsa ntawm lub tog raj kheej lub tog raj kheej yog ua tiav siv lub tshuab honing los yog dov, txo qhov roughness ntawm qhov chaw mus rau hauv qab Ra0.4 thiab tsim cov txheej txheem txias ua haujlwm los txhim kho kev qaug zog.
02
Kev kho saum npoo
Qhov saum npoo ntawm piston pas nrig yog kho nrog nyuaj chrome plating nrog lub thickness ntawm 0.05-0.1 hli. Tom qab plating, sib tsoo yog ua kom tshem tawm burrs.
03
Tsis yog -Kev kuaj kev puas tsuaj (NDT)
Tag nrho cov welds raug tshuaj xyuas siv ultrasonic kuaj (UT) lossis kuaj hluav taws xob (RT) kom ua tau raws li cov cai ntawm JB4730 Standard: Qib I rau kev kuaj ultrasonic thiab Qib II rau kev kuaj hluav taws xob.

Qhov no tso cai rau ob qho tib si hydraulic twj tso kua mis siv 100% ntawm lub cav fais fab, ua kom muaj zog txaus tawm hauv txhua qhov kev ua haujlwm. |
Electronically tswj thiab tswj los ntawm lub tshuab ECM, nws txhim kho lub voj voog lub sij hawm thiab roj efficiency, ua kom cov khoom tsim tau thiab txo cov nqi khiav lag luam. |
Cushions nyob rau ntawm tus pas nrig kawg ntawm lub tog raj kheej boom thiab ntawm ob qho kawg ntawm lub tog raj kheej. Lawv txo qis kev poob siab, txo qis suab nrov, thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom thiab cov qauv. |
Lub hydraulic system muab qhov tseem ceeb tsis siv neeg rau boom nqa thiab ua haujlwm viav vias. Tsis tas yuav nquag siv hom xaiv khawm; lub kaw lus cia li muab qhov tseem ceeb rau cov haujlwm no raws li tus neeg teb xov tooj nkag. |
Kev ceev faj rau kev siv
Hydraulic Roj yuav tsum tau
Lub viscosity ntawm cov roj ua hauj lwm yuav tsum yog 29 ~ 74 mm² / s, thiab cov roj khiav hauj lwm kub yog qhov zoo tshaj plaws nyob rau hauv thaj tsam ntawm -20 ~ 80 degree. Qhov system pom precision yuav tsum tsis txhob qis dua 80 μm. Tswj nruj nruj kom tsis txhob muaj roj paug, tswj cov roj kom huv, xyuas cov roj ua haujlwm tsis tu ncua, thiab hloov cov roj hydraulic kom raws sijhawm.
Installation Notes
Thaum lub sij hawm kev teeb tsa, kev taw qhia ntawm kev sib koom ua ke nyob rau sab saum toj ntawm lub piston pas nrig yuav tsum ua raws li lub tog raj kheej lub taub hau thiab lub trunnion / tsej, thiab qhov ncaj ntawm tag nrho piston pas nrig thaum txuas ntxiv thiab thim rov qab yuav tsum tau ua kom ntseeg tau kom tsis txhob muaj kev cuam tshuam nruj thiab tsis tsim nyog. Ua ntej siv, lub tog raj kheej yuav tsum tau los ntawm huab cua nyob rau hauv qis qis thiab qis ceev, txav nws rov qab thiab tawm txog nees nkaum zaug kom tag nrho cov cua tshaj tawm.
Kev tu
Tsis tu ncua xyuas cov dej xau, hnav, lossis puas, thiab hloov cov ntsaws ruaj ruaj raws li tau teem tseg. Siv cov roj hydraulic pom zoo thiab ntxiv cov nqi tsim nyog kom ua haujlwm tau zoo. Ua ntej disassembly, ua ntej loosen lub nyem valve kom txo tau siab nyob rau hauv lub hydraulic Circuit Court rau xoom, ces txiav tawm lub hwj chim mov thiab nres lub hydraulic syst.
Pob zeb
Pob zeb yog ib lub chaw muag khoom ntawm engineering machinery qhov chaw, tsom mus rau kev muab siab -qhov zoo rau cov tuam txhab mining. Txij li thaum nws tsim nyob rau hauv 2004, peb tau nyob rau hauv Shanghai, Tuam Tshoj, thiab tau tsim peb tus kheej hom STONE, ua ib tug ntseeg kev xaiv nyob rau hauv kev lag luam. Peb tau cog lus tias yuav muab ntau yam xws li bulldozers, excavators thiab log loaders rau zoo-paub hom xws li Kab ntsig thiab Komatsu. Peb cov khoom lag luam npog ntau yam ntawm OEM qhov chaw, xws liTrack Chain, Track Rollers, Sprocket, Excavator thoob, Hniav, Excavator Lub tog raj kheej, viav vias voj voog, thiab ntau yam khoom siv hluav taws xob thiab hydraulic kom ntseeg tau tias peb cov neeg siv khoom nruj yuav tsum tau ua kom zoo thiab ua tau zoo.

Q＆A
Dab tsi ua rau tsis muaj zog boom ua haujlwm?
Tej zaum nws yuav yog vim hnyav hnyav ntawm lub piston seals hauv lub tog raj kheej, ua rau sab hauv ntawm cov roj hydraulic thiab tiv thaiv lub tog raj kheej los ntawm kev tsim kom muaj zog txaus. Nws kuj tuaj yeem yog lub twj tso kua mis hydraulic ua haujlwm ua rau tsis txaus txaus thiab siab ntawm cov roj hydraulic tso tawm. Cov ntsaws ruaj ruaj thiab hydraulic twj tso kua mis yuav tsum tau tshuaj xyuas kom sai thiab hloov yog tias tsim nyog.
Dab tsi ua rau boom drift (tsis xav txo qis)?
Qhov no feem ntau cuam tshuam nrog cov roj foob puas hauv lub tog raj kheej. Thaum cov ntsaws ruaj ruaj puas lawm, hydraulic roj xau los ntawm cov chaw kaw tsis zoo, ua rau lub tog raj kheej tsis muaj zog kom ruaj khov. Nws kuj tseem tuaj yeem tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm lub pob valve, xws li lub pob valve core lossis lub caij nplooj ntoos hlav ua tsis tiav. Cov roj ntsaws ruaj ruaj thiab qhov sib npaug valve yuav tsum tau tshuaj xyuas, thiab txhua qhov chaw puas yuav tsum tau hloov raws sijhawm.
Kuv yuav ua li cas yog tias cov roj hydraulic overheats thiab ua rau lub tswb?
Koj yuav tsum kuaj xyuas thiab ntxuav lub tshuab hluav taws xob, xyuas qhov nruj ntawm txoj siv kiv cua, siv cov roj hydraulic uas tsim nyog, tsis txhob siv lub sijhawm ntev, tshuaj xyuas thiab kho cov hydraulic system siab, tshuaj xyuas thiab kho cov khoom siv hydraulic, nruab ib lub tshuab plua plav, thiab xyuas cov pa cua.
