Cov hniav thoob ntawm lub tshuab khawb av yog ib qho ntawm cov khoom puas tsuaj tseem ceeb ntawm lub tshuab khawb av, zoo ib yam li cov hniav tib neeg, nws muaj cov hniav thiab cov adapters, uas txuas nrog los ntawm tus pin thiab tus tuav. Vim yog qhov hnav thiab rhuav ntawm lub thoob, cov hniav yog qhov tsis raug, tsuav yog cov hniav raug hloov.

1, Cov qauv thiab kev ua haujlwm ntawm cov hniav thoob
Raws li lub hauv paus hniav thoob. Feem ntau, muaj ob hom hniav thoob ntawm cov excavators, uas yog ncaj qha mounted thiab transverse mounted. Kev teeb tsa ntsug txhais tau tias lub pin ncej yog vertically mounted nrog lub ntsej muag pem hauv ntej ntawm lub thoob hniav khawb; hom kev teeb tsa kab rov tav txhais tau tias kev teeb tsa parallel ntawm lub pin ncej thiab lub ntsej muag pem hauv ntej ntawm lub thoob hniav khawb.
(Kev teeb tsa ntsug / kab rov tav)

Hom kev teeb tsa ntsug: nws yooj yim rau kev rhuav tshem thiab teeb tsa ncaj qha los ntawm saum toj no nrog qhov chaw ua haujlwm loj. Thaum lub sijhawm khawb av, lub koob hniav uas tau teeb tsa ncaj qha yuav raug rau lub zog extrusion ntawm cov khoom khawb av. Yog tias lub zog khawb av loj, lub zog clamping ntawm lub caij nplooj ntoos hlav nce tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, uas yuav yooj yim ua rau lub koob hniav poob tawm.

Yog li ntawd, hom kev teeb tsa ntsug feem ntau yog siv rau hauv cov excavators nrog cov excavators me dua thiab qis dua tonnage.

Hom kev teeb tsa kab rov tav: nws tsis yooj yim rau kev rhuav tshem, qhov chaw ua haujlwm sab me me, lub zog nyuaj dua, thaum rhuav tshem ib lub thoob hniav, nws yuav tsum tau rhuav tshem kom siv cov cuab yeej pas nrig ntev tshwj xeeb. Hauv kev khawb av, pem hauv ntej ntawm lub iav transverse yuav tsis raug rau lub siab ntawm cov khoom khawb av, thiab tuaj yeem tiv taus lub zog khawb av, tab sis lub caij nplooj ntoos hlav o thaum siv lub zog rov qab, yooj yim hnav, ua tsis tiav, ua rau cov hniav poob tawm.

Yog li ntawd, qhov kev teeb tsa kab rov tav feem ntau yog siv rau hauv lub zog khawb av ntau dua 20 tons ntawm lub tshuab khawb av.

Raws li kev siv cov hniav thoob ntawm lub tshuab khawb av, kev faib tawm ib puag ncig. Cov hniav thoob ntawm lub tshuab khawb av tuaj yeem muab faib ua cov hniav pob zeb (rau cov hlau, pob zeb, thiab lwm yam), cov hniav av (rau kev khawb av, xuab zeb, thiab lwm yam), cov hniav conical (rau cov chaw khawb thee). Tab sis cov duab ntawm cov hniav thoob ntawm cov tshuab khawb av sib txawv kuj muaj nws tus yam ntxwv.

(Cov hniav pob zeb/cov hniav av/cov hniav cone)

Vim li cas cov neeg khawb av thiaj li ntsia cov hniav thoob? Muaj ntau cov hniav thoob, peb kuj tuaj yeem pom:

1. Tiv thaiv tag nrho lub thoob. Cov hniav thoob yog cov khoom hnav, vim tias lub thoob thaum lub sijhawm ua haujlwm hnav, ua ke nrog cov hniav thoob, rau qee qhov los tiv thaiv lub thoob.

2. Ua kom txoj haujlwm ua haujlwm ntau dua. Rau cov haujlwm me me, nws tsis yooj yim sua kom ua tiav yam tsis muaj cov hniav thoob.

3. Yooj yim rau khawb thiab khawb. Cov hniav thoob yog conical, cov hniav thoob thiab cov hniav ntawm nruab nrab yog ib qho dawb paug, yog li lub zog ntawm tag nrho lub thoob, qhov chaw ua haujlwm me me, qhov siab yuav nce ntxiv, txoj haujlwm yuav du dua.

4. Nws tuaj yeem buffer tag nrho lub tshuab tom qab khawb cov khoom nyuaj.

2. Kev yuav cov hniav thoob
Feem ntau, muaj qhov sib txawv ntawm cov hniav thoob uas raug cam thiab cov hniav uas raug forged. Feem ntau, cov hniav thoob uas raug forged muaj zog dua thiab tawv dua. Lub neej ua haujlwm ntawm cov hniav thoob uas raug forged yog li 2 npaug ntawm cov hniav thoob uas raug cam, thiab tus nqi yog li 1.5 npaug ntawm cov hniav thoob uas raug cam.
Kev pov cov hniav thoob: pov cov hlau ua kua rau hauv qhov chaw pov uas sib haum rau cov duab ntawm qhov, thiab tom qab ntawd txias thiab khov cov hlau ua kua kom tau txais cov khoom lossis cov khoom seem hu ua kev pov. Cov khoom siv kho tshuab, kev tiv thaiv kev hnav thiab lub neej ua haujlwm ntawm kev pov qis dua li cov kev zam.
Kev sib tsoo cov hniav thoob: cov tshuab forging yog siv los ua kom muaj kev nyuaj rau cov hlau tshwj xeeb, uas yog extruded ntawm qhov kub siab los ua kom cov khoom siv siv lead ua hauv kev sib tsoo los tsim cov yas deformation kom tau txais qee yam khoom siv kho tshuab. Tom qab kev sib tsoo, cov qauv ntawm cov hlau tuaj yeem txhim kho, uas tuaj yeem ua kom ntseeg tau tias cov hniav thoob muaj cov khoom siv kho tshuab zoo, tiv taus kev hnav ntau dua thiab lub neej ua haujlwm ntev dua.
Tau kawg, thaum yuav cov hniav thoob, peb kuj yuav tsum pom hom hniav thoob uas lub tshuab khawb av siv rau hauv txhua qhov chaw ua haujlwm.
Kev khawb av dav dav, xuab zeb xoob, thiab lwm yam kom siv cov hniav thoob tiaj tiaj. Qhov thib ob, cov hniav thoob hom RC siv rau kev khawb cov pob zeb tawv loj, thiab cov hniav thoob hom TL feem ntau siv rau kev khawb cov thee loj.
Ntxiv mus, nyob rau hauv cov txheej txheem ua haujlwm tiag tiag, feem ntau cov neeg nyiam cov hniav thoob RC. Tus kws kho me me qhia tias cov hniav thoob RC hom yuav tsum tsis txhob siv dav dav, thiab cov hniav thoob lub qhov ncauj tiaj tus yuav tsum tau siv zoo dua, vim tias tom qab cov hniav thoob RC hnav rau ib lub sijhawm, qhov kev tiv thaiv khawb tau nce ntxiv thiab lub zog raug pov tseg, thaum cov hniav thoob lub qhov ncauj tiaj tus ib txwm tswj qhov chaw ntse hauv cov txheej txheem hnav, yog li txo qhov kev tiv thaiv khawb thiab txuag roj.

3, kev saib xyuas cov hniav thoob thiab ua kom lub neej ua haujlwm ntev dua ntawm qhov kev thov

1. Thaum siv cov hniav thoob ntawm lub tshuab khawb av, cov hniav thoob sab nraud tshaj plaws yog 30% sai dua li cov khoom hnav sab hauv tshaj plaws. Tom qab ib lub sijhawm, sab hauv thiab sab nraud ntawm cov hniav thoob tuaj yeem pauv tau.
2. Thaum lub sijhawm ua haujlwm, tus tsav tsheb ntawm lub tshuab khawb av yuav tsum tig mus rau lub ntsej muag ua haujlwm thaum khawb hauv qab cov hniav thoob kom tsis txhob tawg cov hniav thoob vim muaj lub kaum sab xis ntau dhau.
3. Tsis txhob co lub caj npab khawb av los ntawm ib sab mus rau ib sab yog tias muaj kev tiv thaiv zoo, vim tias nws yooj yim tawg cov hniav thoob thiab cov hniav hauv paus vim muaj zog ntau dhau ntawm sab laug thiab sab xis, yam tsis xav txog qhov tsim lub zog ntawm sab laug thiab sab xis.
4 thaum lub hauv paus hniav hnav tawm 10% tom qab cov lus pom zoo kom hloov lub hauv paus hniav, hnav lub hauv paus hniav loj dhau thiab cov hniav thoob muaj qhov sib txawv loj, yog li cov hniav thoob thiab cov hniav hauv paus sib koom ua ke, thiab qhov chaw quab yuam tau hloov pauv, cov hniav thoob vim qhov kev hloov pauv ntawm qhov chaw quab yuam thiab tawg.
