Dab tsi RPM txiav granite?

Qhov ceev ntawm kev txiav granite tsis muaj tus nqi ruaj khov, nws tsuas yog nyob ntawm txoj kab uas hla ntawm cov saw hniav. Qhov loj ntawm txoj kab uas hla, qhov qis dua qhov xav tau kev sib hloov ceev.

 

Rau kev txiav pob zeb, ib qho kev tswj xyuas ntau tshaj plaws yog linear ceev. Thaum txiav granite, linear ceev ntawm pob zeb diamond saw hniav feem ntau yog tswj ntawm25m / s thiab 35m / s.Rau granite nrog cov ntsiab lus siab quartz thiab tshwj xeeb tshaj yog tawv tawv, tus nqi qis dua (ib ncig 25m / s) yuav tsum tau noj.

Cov hauv qab no yog cov lus qhia rau kev pom zoo kab ceev ntawm cov saw hniav nrog txawv diameters:

Txoj kab uas hla ntawm Hniav	Pom zoo ceev (rpm)	Kev nyab xeeb siab tshaj plaws (rpm)
110	5200-7300
350	2592	5500
400	2268	3820
500	1814	3055
600	1512	2550
900	1008	1700
1200	756	1275
1800	455
2200	408
2500	327

* Nco tseg:

• Kev sib hloov ceev hauv cov lus saum toj no feem ntau yog cov txiaj ntsig theoretical xam raws li "linear velocity=30m/s". Hauv kev siv tiag tiag, thov nco ntsoov ua raws li "qhov siab tshaj plaws" cim ntawm cov khoom siv sawb thiab tsis txhob tshaj tus nqi no
• Cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb, thov ua tib zoo saib xyuas

 

 

Cov xwm txheej ceev ntawm cov khoom siv sib txawv
Cov hauv qab no yog qhov tseeb ceev tsis tau ntawm ntau yam khoom siv granite txiav, uas tuaj yeem ua rau koj xav paub ntau ntxiv:

• Loj choj txiav tshuab: Hom kev tshaj lij no siv cov saw hniav nrog cov kab uas loj dua (xws li Φ 350-450mm), thiab cov spindle ceev feem ntau yog nyob ib ncig ntawm 6000 rpm.
• Lub tshuab txiav me me: Piv txwv li, lub tshuab txiav pob zeb tsis tu ncua nrog lub zog ntawm 3-4kw, thaum siv Φ 350-500mm saw hniav, qhov ceev yog li 2340 rpm.
• Handheld txiav tshuab:

Cov cuab yeej pneumatic nrog Φ 110mm pom hniav tuaj yeem ncav cuag qhov nrawm ntawm 12000 rpm thiab tsim nyog rau kev txiav cov ntawv hlau zoo.

Kuj tseem muaj cov qauv siv tes nrog qhov ceev ntawm 6500 rpm rau qhov chaw txiav loj.

 

Cov ntsiab cai tseem ceeb thiab kev suav
Yog tias koj xav nrhiav qhov nrawm tshaj plaws rau koj cov saw hniav uas twb muaj lawm, koj tuaj yeem ua raws li lub hauv paus ntsiab lus no: qhov ceev yuav tsum phim txoj kab uas hla ntawm cov saw hniav.

 

Koj tuaj yeem siv cov qauv no los xam cov kev siv ceev:
Reference ceev (rpm)=(kab ceev (m/s) × 60 × 1000)/( pom hniav txoj kab uas hla (mm) × π)

 

Hloov cov linear tshaj tawm ntawm 30m / s rau hauv cov qauv thiab ua kom yooj yim nws li:
Siv ceev ≈ 573000 / pom hniav txoj kab uas hla (mm)

 

Piv txwv li, ib tug saw hniav nrog ib txoj kab uas hla ntawm 180mm muaj ib tug siv ceev ntawm kwv yees li 573000/180 ≈ 3183 rpm.

 

Thaum kawg, nws yuav tsum tau muab sau tseg tias kev xaiv siab - zoo pob zeb diamond saw hniav tuaj yeem tsis tsuas yog txhim kho kev ua haujlwm ntawm kev txiav granite, tab sis kuj txo qis kev pheej hmoo. Xaiv Huice pob zeb diamond granite pom cov hniav tuaj yeem pab cov neeg siv txhim kho kev ua haujlwm ntawm kev txiav granite.

Thaum siv lub kaum sab xis ntawm tes los txiav granite, ntxiv rau kev xaiv qhov tsim nyog ceev, kev txiav ntub dej (dej txias) yuav tsum tau siv los tiv thaiv cov saw hniav thiab tus neeg teb xov tooj kev noj qab haus huv, thiab plua plav qhov ncauj qhov ntswg thiab tsom iav yuav tsum hnav.
