Ⅰ. Dab tsi yog qhov siab tshaj plaws quab yuam hnyav hnyav lub tog raj kheej tuaj yeem tsim tau?
Heavy duty nyem lub tog raj kheejmuaj peev xwm ua tau zoo heev, xws li 50 tons mus txog 16, 000 tons lossis ntau dua. Lub zog siab tshaj plaws nyob ntawm yam xws li:
- Lub tog raj kheej bore txoj kab uas hla - loj bores siv zog ntau dua
- Kev khiav hauj lwm siab - hydraulic siab mus txog 10, 000 PSI ua kom muaj zog clamping ntau dua
- Piston pas nrig txoj kab uas hla - cov pas nrig loj tuaj yeem ua haujlwm siab dua yam tsis muaj kev khoov
- Cov khoom siv zog - High-strength alloys tuav cov kev ntxhov siab ntau dua
Piv txwv li, ib tug 36-inch bore lub tog raj kheej nrog ib tug 10-inch pas nrig ntawm 5000 PSI tuaj yeem tsim ib ncig ntawm 2000 tons ntawm lub zog tas mus li. Custom-designed cylinders tuaj yeem ua kom muaj peev xwm ntau dua.
Ⅱ.Qhov ntev stroke ntev yog dab tsi?
Heavy duty nyem lub tog raj kheejfeem ntau yog tsim nrog cov kab mob stroke ntev li ntawm ob peb ntiv tes mus txog 120 ntiv tes lossis ntau dua. Hom mob stroke ntev yog daim ntawv thov-nyob ntawm:
- Qhwv balers thiab compactors - 24-60 ntiv tes
- Hlau stamping nias - 6-36 ntiv tes

- Kev ua haujlwm hnyav heev - 8, 000 txog 10, 000 PSI
Pneumatic nyem lub tog raj kheej ua haujlwm ntawm qhov qis qis, feem ntau 100 txog 150 PSI. Txawm li cas los xij, cov tshuab pneumatic tuaj yeem siv zog nrog cov boosters kom ncav cuag 1500 PSI.
Lub peev xwm siab dua yuav tsum tau siv lub tog raj kheej zoo dua - cov phab ntsa tuab tuab, qhov kawg kaw, cov ntsaws ruaj ruaj, thiab lwm yam.
Ⅳ. Cov ntaub ntawv dab tsi yog siv los ua nws?
Nws yog tsim los ntawm cov khoom siv rugged engineered los tswj kev kub siab, hnav, thiab cuam tshuam kev thauj khoom:
- chim - siab zog steel alloys zoo li 4140 los yog 8620 steel. Yuav tsum tau zoo machinability.
- Qws - hardened chrome plated 4140 steel los yog stainless hlau rau corrosion kuj
- Seals - abrasion resistant polyurethane los yog hydrogenated nitrile (HNBR)
- Cov kaus mom kawg - steel nrog tuab phab ntsa kom tiv thaiv deformation ntawm kev kub ntxhov
- Bearings - hnyav bronze los yog tshwj xeeb coated hlau bearings
Cov ntaub ntawv raug xaiv raws li kev ua haujlwm ntawm lub tog raj kheej thiab lub neej yuav tsum tau ua. Customized coatings los yog kev kho mob zoo li nitriding tuaj yeem txhim kho hnav tsis kam thiab ua haujlwm ntev.
Ⅴ. Kuv yuav ua li cas tuav thiab pab lub tog raj kheej nyem?
Kev saib xyuas kom zoo txhim kho lub sijhawm ua haujlwm thiab txuas ntxiv lub neej kev pabcuam ntawm lub tog raj kheej hnyav nyem:
- Tshawb xyuas tsis tu ncua rau kev xau, kev puas tsuaj, kev sib txuas xoob lossis kev sib raug zoo
- Khaws lub tog raj kheej sab nrauv kom huv - siv cov kuab tshuaj thiab cov ntaub qhwv tsis muaj lint
- Lubricate txav qhov chaw xws li pas nrig bearings raws li OEM cov lus qhia
- Saib xyuas cov kua dej hydraulic zoo - hloov cov lim dej thiab kuaj kev sib kis
- Rov tsim cov ntsaws ruaj ruaj tsis tu ncua - tshuaj xyuas kev txiav, hnav, thiab kev teeb tsa kom raug
- Tshawb xyuas thiab rov ua dua txhua qhov kev sib txuas thiab txuas kho vajtse
- Hloov cov hoses puas thiab fittings
- Siv cov ntxaij lim dej lossis lub tshuab ua pa kom tiv thaiv kev sib kis sab hauv
- Ua raws li cov txheej txheem ua txhaum cai ntawm lub tog raj kheej tshiab
- Nkag mus rau lub voj voog, lub siab nce siab, thiab qhov txawv txav los txheeb xyuas cov teeb meem ntxov
Kev rov tsim kho loj yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog nyob rau hauv ib puag ncig kev kho lub khw. Nrog kev tiv thaiv kev saib xyuas thiab kev kho kom zoo,Heavy duty nyem lub tog raj kheejtuaj yeem ua haujlwm ruaj khov rau ntau xyoo.
Ⅵ.Yuav ua li cas hnyav lub tog raj kheej nyem piv rau lwm txoj kev siv lub zog?
Kev xaiv ntawm lub tog raj kheej nyem los yog lwm txoj hauv kev yog nyob ntawm cov kev xav tau tshwj xeeb, suav nrog lub zog xav tau, kev ua haujlwm ceev, kev tswj xyuas qhov tseeb, qhov txwv loj, ib puag ncig, thiab lwm yam xws li nqi, kev saib xyuas, thiab kav ntev.
1. Heavy Duty Squeeze Cylinder:
- Cov no feem ntau pneumatically lossis hydraulically powered.
- Lawv tsim lub zog los ntawm cov dej ntws los yog huab cua, uas txav lub piston nyob rau hauv lub cylindrical chamber.
- Lub zog siv yog qhov ua haujlwm ntawm huab cua lossis kua dej thiab thaj tsam ntawm lub piston.

- Tej zaum lawv yuav tsis muaj zog li hydraulic rams yog tsim los rau qis dua.
2. Hydraulic Rams:
- Ua haujlwm siv cov kua dej hydraulic siab.
- Muaj peev xwm siv zog loj heev vim tias lub zog siv yog proportional rau lub siab sib npaug los ntawm thaj tsam piston.
- Lawv muab lub zog ruaj khov thiab tswj tau thiab siv qhov chaw nqa hnyav lossis muaj zog compression xav tau.
- Feem ntau siv rau hauv daim ntawv thov uas yuav tsum muaj zog, khov kho es tsis yog nyem.
- Kev tswj ceev tuaj yeem ua tau zoo me ntsis piv rau cov tshuab cua hauv huab cua vim tias cov kua dej tsis sib haum.
3. Screw Presses:
- Lawv hloov txoj kev sib hloov mus rau hauv lub zog linear.
- Lub zog yog siv maj mam, uas tuaj yeem yog qhov zoo lossis qhov tsis zoo nyob ntawm daim ntawv thov.
- Lawv zoo li muaj kev ua haujlwm qeeb qeeb tab sis tuaj yeem ua tiav qhov siab heev.
- Zoo rau cov ntawv thov uas xav tau lub zog siab thiab qhov tseeb ntawm qhov nrawm nrawm, zoo li cov hlau sib sau los yog compaction.
- Cov khoom siv kho tshuab tuaj yeem raug kev txom nyem los ntawm kev hnav thaum lub sijhawm vim muaj kev sib txhuam hauv kev ua si.
4. Actuators (ob qho tib si linear thiab rotary):
- Nws tuaj yeem siv los ntawm pneumatic, hydraulic, hluav taws xob, lossis kev siv tshuab.
- Lawv tuaj yeem muab kev tswj xyuas meej ntawm txoj haujlwm, nrawm, thiab quab yuam.
- Hluav taws xob actuators huv si thiab tuaj yeem ua tau zoo heev tab sis feem ntau tsis muaj zog ntau npaum li cov tshuab hydraulic.
- Pneumatic actuators muab kev txav ceev thiab ua tau zoo ntawm kev ceev ceev, kev siv cyclic nrog qis zog yuav tsum tau.
- Hydraulic actuators tuaj yeem siv zog siab heev thiab tuaj yeem tswj tau meej tab sis nyuaj dua thiab xav tau lub zog ua kua dej, feem ntau ua rau lawv loj dua thiab tsis haum rau qee qhov chaw.
