Load & Kev Ua Haujlwm

Tsim kom muaj lub neej ua haujlwm ntev yuav tsum tau ntsuas lub cev muaj zog, kev txwv tsis pub siv tshuab, thiab ib puag ncig ib puag ncig.
Static & Dynamic Force Output
Push Force: Force_push=P * A_p=P * (pi * D^2) / 4
Pull Force: Force_pull=P * (A_p - A_r)=P * [pi * (D^2 - d^2)] / 4
(Qhov twg P=Ua Haujlwm Siab, D=Lub tog raj kheej bore Diameter, d=Piston Rod Diameter)
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm

FAQ

Q: Dab tsi yog qhov tseem ceeb ua rau thaum ntxov piston foob tsis ua haujlwm hauv siab - lub tog raj kheej siab?

A: Thaum ntxov piston foob tsis ua hauj lwm feem ntau tshwm sim los ntawm cov roj paug, thermal degradation, los yog extrusion los ntawm qhov sib txawv clearances thaum lub sij hawm siab spikes. Kev siv cov PTFE cov ntsaws ruaj ruaj thib ob, rov qab- cov nplhaib, thiab kev tswj xyuas cov roj pom ntawm ISO 4406 16/14/11 los yog lub tshuab nqus tsev vacuum tiv thaiv cov foob pob ua ntej ntxov.

Q: Yuav ua li cas induction hardening txhim kho piston pas nrig kev ua tau zoo?

A: Induction hardening tsub kom lub hardness ntawm tus pas nrig mus rau 55 mus rau 60 HRC ntawm qhov tob ntawm 1.5 mus rau 3.0 hli. Cov ntaub ntawv subsurface qhov tob no tiv thaiv cov khoom siv dents, pob zeb cuam tshuam, thiab khawb uas yuav txwv tsis pub cov hlua khi thiab ua rau cov kua dej tawm sab nraud.

Q: Thaum twg tus qauv tsim lub tog raj kheej yuav tsum suav nrog qhov kawg - ntawm - stroke cushioning?

A: Xaus- ntawm -stroke cushioning yuav tsum tau teev tseg thaum twg piston ceev tshaj 0.1 m/s los yog thaum hnyav coj pawg tsim siab kinetic zog ntawm stroke kawg. Cushions decelerate lub piston smoothly dhau qhov kawg ntawm 15 mus rau 25 hli ntawm kev mus ncig, tiv thaiv kev ua haujlwm siab tiv thaiv lub taub hau / hau.

Q: Dab tsi yog qhov txiaj ntsig ntawm kev tsim lub cev welded tshaj khi- qauv qauv?

A: Welded lub cev lub tog raj kheej muab lub hnab ntawv me me, ua kom muaj zog dua rau cov qauv kev qaug zog nyob rau hauv lub zog dynamic bending loads, thiab tshem tawm txoj hlua khi - qws elongation txaus ntshai thaum lub sij hawm siab - siab spikes. Welded designs yog nyiam rau cov khoom siv hnyav hnyav uas qhov chaw thiab cov qauv kev ncaj ncees yog qhov tseem ceeb.

Q: Yuav ua li cas sab loading nyob rau hauv ntev -stroke daim ntawv thov?

A: Kev thauj khoom sab nraud yog tswj hwm los ntawm kev nce qhov kev ncua deb ntawm lub piston thiab lub taub hau kev qhia bushings (stop tubes), kev sib koom ua ke ntawm cov nplhaib uas muaj peev xwm thauj khoom siab (xws li tooj liab - puv PTFE lossis woven npuag resin), thiab siv spherical eyelet bearings los tshem tawm cov khoom siv khoov lub sijhawm.

Q: Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) cov qauv siv rau cov welds tseem ceeb?

A: Cov txheej txheem welds raug kuaj xyuas Ultrasonic (UT) raws li ISO 17640 thiab Sib Nqus Particle Inspection (MPI) rau ISO 17638. Weld zoo qib ua raws li ISO 5817 Qib B, kom tsis txhob muaj cov voids sab hauv lossis cov kab nrib pleb tshwm sim ua ntej dynamic siab ntsuas.
