Heavy-Lub luag haujlwm Welded Hydraulic Lub tog raj kheej

Peb hnyav-lub luag haujlwm welded hydraulic lub tog raj kheej yog tsim los rau cov ntawv thov uas muaj qhov hnyav hnyav thiab hnyav hnyav. Lub thoob thiab lub kaus mom kawg muaj tag nrho -kev nkag welds. Cov qauv welded tshem tawm cov hlua khi, tshem tawm cov ntsiab lus ntawm kev ntxhov siab thiab txhim kho kev qaug zog piv rau cov qauv khi pas nrig.

Qhov ntsuas kev ua haujlwm siab yog li ntawm 25 txog 31.5 MPa, nrog qhov ntau thiab tsawg ntawm 100 mus rau 500 hli. Qhov siab tshaj plaws tuaj yeem ncav cuag 6 meters. Lub piston pas nrig txoj kab uas hla yog ua tib zoo sib xyaw nrog cov tho qhov loj kom ntseeg tau tias muaj kev tiv thaiv zoo rau sab loads.

Qhov hnyav no -lub luag haujlwm welded hydraulic lub tog raj kheej suav nrog cov qauv kev taw qhia ntxiv, nrog cov lus qhia ntev ntawm tsawg kawg yog 0.8 npaug ntawm txoj kab uas hla rau kev txhim kho kev ruaj ntseg hauv cov khoom hnyav.

Lub piston pas nrig yog tawv chrome plated nrog qhov tsawg kawg nkaus thickness ntawm 40 μm. Ceramic spray txheej kuj muaj rau kev txhim kho hnav thiab corrosion kuj.

Lub kaw lus sealing siv cov khoom siv tseem ceeb ntawm polyurethane cov ntsaws ruaj ruaj, ob lub nplhaib plua plav, thiab cov ntsaws ruaj ruaj, muab kev ua haujlwm ruaj khov nyob rau hauv ib puag ncig nrog av nkos, plua plav, thiab kev sib kis hnyav.

Cov ntawv thov muaj xws li excavator boom thiab caj npab lub tog raj kheej, khib nyiab compactor lub ntsiab thawb lub tog raj kheej, thee mine hydraulic txhawb nqa, thiab chaw nres nkoj crane luffing thooj voos kheej kheej. Lub tog raj kheej no yog tsim los rau kev ua haujlwm tas mus li hauv qhov xav tau ib puag ncig.

Kev cai clevis qhov ntev, tiv thaiv- cov coatings corrosion, thiab lwm qhov chaw sensors muaj nyob rau ntawm kev thov. Rau siab - daim ntawv thov kev cuam tshuam, ib qho - daim forged piston pas nrig tuaj yeem siv los txhim kho cov txheej txheem ntxiv.

Peb muab finite element tsom xam (FEA) cov lus ceeb toom los xyuas cov qauv kev ncaj ncees, qhia tau hais tias lub tog raj kheej yuav tsis muaj deformation mus tas li ntawm 1.5 npaug ntawm cov ntsuas siab.

Peb tau muab cov cuab yeej siv rau Zoomlion rau kev siv excavator, nrog rau cov tuam txhab tsim choj siv tshuab thiab cov cuab yeej tuag casting. Peb lub Hoobkas muaj tshaj 2,000 m² ntawm qhov chaw tsim khoom thiab pab pawg tsim khoom. Txhua yam khoom raug tshuaj xyuas ua ntej xa khoom, thiab peb muab 12 lub hlis lav.
