Trapezoidal Ntsia Hlau Jacksyog engineered rau ntsug linear lifting kis tau tus mob. Calibrated ua ntej xa khoom, vaj tse thiab cov ntsia hlau ua kom muaj kev sib raug zoo. Thaum txhim kho kom raug, raug rau cov teeb tsa ntsug thiab ua raws li cov lus qhia tshwj xeeb, lub jack ua haujlwm ruaj khov yam tsis muaj kev cuam tshuam sab nraud, txaus siab rau kev lag luam nqa thiab qib kev xav tau. Txawm li cas los xij, tsis yog -tus qauv kev ua haujlwm, kev teeb tsa tsis tu ncua thiab kev ua haujlwm tsis raug ua rau muaj kev cuam tshuam rau sab nraud thiab ua rau muaj kev sib txawv ntawm kev hloov ntawm sab, ua ib qho kev nyab xeeb tshaj plaws ntawm qhov chaw.
Lub ntsiab contributor rau lifting deflection yog uneven loading thiab offset nruab nrab ntawm lub ntiajteb txawj nqus. Cov cuab yeej no yog tsim tshwj xeeb rau axial ntsug loads thiab tsis tuaj yeem tiv taus lateral lossis eccentric rog. Yog hais tias lifted workpieces yog tilted nrog offset lub ntiajteb txawj nqus, los yog ntau synchronized jacks dais tsis sib xws loads nrog inconsistent strokes, persistent lateral tivthaiv rog cuam tshuam ntsug kev nyuaj siab tshuav nyiaj li cas. Nyob rau hauv lateral quab yuam, cov hlau lead ntsia hlau deviates los ntawm nws lub hauv paus ntsug axis. Lub sab hloov ntau ntxiv raws li kev nqa mus ncig, tilting workpieces thiab impairing positioning raug. Meanwhile, unilateral xov abrasion accelerates dramatically.
Qhov thib ob, kev teeb tsa tsis tu ncua ua rau muaj qhov cuam tshuam sab nraud. Tsis sib xws mounting bases, tilted av, thiab xoob kho bolts ua rau verticality sib txawv los ntawm thawj theem installation. Thaum lub sij hawm lifting, cov hlau lead ntsia hlau hloov tsis tu ncua mus rau inclined kev taw qhia thiab cov ntaub ntawv ruaj deflection qhov tseem ceeb. Tsis tas li ntawd, kev ywj pheej ib qho kev teeb tsa tsis muaj kev sib koom ua ke cov lus qhia thiab kev txwv cov qauv tsis muaj kev txwv sab nraud. Kev co thiab sab hloov feem ntau tshwm sim nyob rau hauv load, sawv cev rau ib tug ua rau deflection rau me me - loj jacks.
Tsis tas li ntawd, kev ua haujlwm tsis tsim nyog thiab kev ua haujlwm ua rau ua rau muaj kev cuam tshuam sab nraud. Kev nqa nrawm nrawm, pib pib thiab kaw hauv qhov hnyav hnyav ua rau muaj kev cuam tshuam tsis zoo uas cuam tshuam kev ruaj ntseg thiab ua rau cov hlau lead ntsia hlau co thiab deflection. Kev pabcuam txuas ntxiv tsim kom muaj qhov loj me ntawm qhov sib txawv los ntawm kev hnav cov hlau lead, bearings thiab lub tes tsho ncej, uas ua rau muaj kev sib cuam tshuam thaum nqa. Overloading ua rau cov qauv deformation thiab amplifies deflection, tsim ib lub voj voog vicious.
Lateral deflection coj qhov tshwm sim loj heev. Kev hloov pauv me me txo qis qhov ntsuas qhov tseeb thiab tsim cov suab nrov txawv txav thiab jamming. Nruab nrab deflection ua rau hnyav unilateral abrasion ntawm trapezoidal threads, lubrication poob thiab ceev rusting thiab seizing. Loj deflection mus tas li khoov cov hlau lead screws thiab tshem tawm cov kab sib txuas sab hauv, ua rau lub jack siv tsis tau. Tsis tas li ntawd, tilted hnyav workpieces yuav poob thiab ua rau muaj kev nyab xeeb xwm txheej. Nyob rau hauv daim ntawv thov, xyuas kom meej kab rov tav installation thiab ntsug nruab nrab loading. Txhim kho cov lus qhia pabcuam thiab txwv cov khoom siv rau hnyav-load thiab siab- cov xwm txheej ceev kom tshem tawm cov kev pheej hmoo ntawm sab nraud.
