Hydraulic Fluid Recommendations
It is recommended to use high quality mineral oil based hydraulic oil, such as HLP oil according to standard DIN51524 part 2. For general use, the Brugger value must be greater than 30 N/mm2; for heavy-duty hydraulic equipment and hydraulic systems with fast cycles and/or heavy dynamic loads, it must be greater than 50 N/mm2, and the determination of the Brugger value shall be in accordance with DIN 51347. -2 provisions. For details, please refer to the document HY30-3248/UK "Hydraulic Fluids for Parker PV Series Axial Piston Pumps".
viscosity
Thaum lub sijhawm ua haujlwm ib txwm, cov roj viscosity yuav tsum nyob ntawm 16 txog 100 mm2 / s (cSt), nrog rau qhov siab tshaj plaws viscosity ntawm 800 mm2 / s (cSt) thaum pib- nce. Lim cov cai
Txhawm rau kom ua tiav txoj haujlwm thiab ua kom lub neej ntev ntawm lub twj tso kua mis hydraulic thiab lwm cov khoom siv hydraulic hauv lub cev, kev ntsuas lim dej yuav tsum tau ua rau cov roj ua haujlwm los tiv thaiv lub cev los ntawm kev sib kis. Kev huv huv ntawm cov roj yog ntsuas los ntawm ISO khoom particle pollution degree raws li ISO 4406: 1999, thiab cov roj yog lim thiab lim los ntawm lub lim. Qhov zoo ntawm cov khoom lim yuav tsum ua tau raws li cov kev cai ntawm cov qauv ISO. Rau cov tshuab hydraulic dav dav, cov roj paug yuav tsum tau ua kom ntseeg tau tias kev ua haujlwm txaus siab tsis siab dua ISO
4406:1999 sau tseg 20/18/15. Yog tias nws yuav tsum tau ua kom lub neej ntev ntawm cov khoom siv hydraulic, cov pa phem ntawm cov roj yuav tsum tsis txhob siab tshaj 18/16/13 tau teev tseg hauv ISO 4406: 1999.
Cov ntsaws ruaj ruaj
Nrog rau hydraulic kua specifications los xyuas cov tshuaj compatibility nrog cov ntaub ntawv foob. Txheeb xyuas qhov ntsuas kub ntawm cov khoom siv sib khi thiab sib piv nrog cov txheej txheem kev khiav hauj lwm thiab qhov ntsuas kub ntawm qhov chaw. N-NBR-40... ntxiv rau 90C Lus Cim: Cov roj kub siab tshaj plaws yuav tshwm sim ntawm qhov chaw nres nkoj ntawm lub twj tso kua mis hydraulic, uas tuaj yeem yog 25 degree siab dua cov roj tank kub.
Technical yam ntxwv
·Low noise ·Fast response
. Tus phooj ywg ua haujlwm ua haujlwm, siab tus kheej -priming ceev, compact qauv
100 feem pua nominal torque los ntawm ncej tsav qauv
- Kev npaj ua haujlwm, sib sau ua ke thiab ua haujlwm ntawm axial piston ntsiab yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog. - Cov chaw nres nkoj ua haujlwm thiab cov chaw nres nkoj ua haujlwm yog tsim los rau cov kab hydraulic nkaus xwb.
- Muaj kev pheej hmoo ntawm kev kub hnyiab los ntawm axial plunger ntsiab (tshwj xeeb tshaj yog cov electromagnets) thaum lub sijhawm thiab tsis ntev tom qab ua haujlwm. Yuav tsum ntsuas kev nyab xeeb kom tsim nyog (xws li hnav khaub ncaws tiv thaiv).
- Nyob ntawm kev ua haujlwm ntawm lub axial piston caij (ua haujlwm siab, roj kub), cov yam ntxwv yuav hloov. -Hloov chaw nres nkoj:
Cov chaw nres nkoj thiab kho cov xov yog tsim los rau qhov siab tshaj plaws uas tau teev tseg. Lub tshuab lossis cov chaw tsim khoom yuav tsum xyuas kom meej tias qhov kev nyab xeeb ntawm cov khoom sib txuas thiab cov kab ua tau raws li cov txheej txheem kev ua haujlwm (siab, ntws, hydraulic roj, kub).
- Cov ntaub ntawv thiab cov lus qhia muaj nyob ntawm no yuav tsum ua raws. - Siv cov hauv qab no kom nruj torque:
Threaded qhov rau axial plunger caij:
Qhov siab tshaj plaws tso cai nruj torque MG max yog tus nqi siab tshaj plaws rau cov xov qhov thiab yuav tsum tsis txhob tshaj. -Connector:
See the manufacturer's instructions for the tightening torque of the fittings used. -Fixing screws:
Hais txog kev kho cov ntsia hlau raws li DIN 13, peb pom zoo kom ib tus neeg kuaj xyuas lawv cov torques nruj raws li VDI 2230. -Txuas screws:
Rau cov hlau locking ntsia hlau nkag nrog lub axial plunger caij, lub zawm torque MV. Yuav tsum tau siv cov ntsia hlau xauv tsis raug pom zoo rau cov khoom no raws li lub tswv yim dav dav ntawm lub tshuab kev nyab xeeb ntawm DIN EN ISO 13849.
