Beskrivelse
UL 651 Slagtester for fallende vekt
(UL651, ASTM D2444, Maks. impact height 4000mm, adjustable test height, anti-second impact)
Hovedfunksjoner
UL651 falling weight impact tester is a combined test machine that newly designed, which can be used for impact test of UL651 Schedule 40, 80, Type EB and A Rigid PVC Conduit and Fittings and ASTM D2444 Thermoplastic Pipe and Fittings.
Arbeidsprinsipp
UL 651 Falling Weight Impact Tester is a free fall dropping impact tester.
This drop weight impact tester is composed of guide rail, base, anvil, hammer and lifting mechanism.
The guide rail of the testing machine is perpendicular to the base, and the base has sufficient rigidity.
The guide rails are kept parallel to guide the hammer to fall freely. The beam is moved up and down through the anchor chain to realize the up and down movement of the hammer body.
Monter røret eller profilen som skal testes på arbeidsbenken, adjust the height of the sample; velg hammerhode og vekt i henhold til kravene i teststandarden, and combine the impact hammer; heng hammeren; start testen, hammeren vil fritt falle av fra den forhåndsinnstilte høyden og støte på prøven.
The microcomputer-controlled impact energy preset system, by presetting the hammer mass and test energy, the testing machine automatically raises the hammer to the required height. Samtidig, the monitoring of safety protection devices can be realized.
The electric lifting mechanism is at the bottom right of the frame, which reduces the height of the whole machine, enhances the stability, and is convenient for maintenance.
Observer bruddet på røret eller profilen, en eller mindre indikerer at slagfastheten til røret eller profilen oppfyller standarden, og mer enn én indikerer at motstanden Slagytelsen ikke oppfyller standarden.
UL 651 Falling Weight Impact Tester offers an apparatus to prevent 2nd strike during testing.
