UL 651 Falling Weight Impact Tester
(UL651, ASTM D2444, Max. taas ng impact 4000mm, adjustable test height, anti-second impact)
Mga pangunahing function
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.
Prinsipyo sa trabaho
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.
Install ang pipe o profile upang masuri sa workbench, adjust the height of the sample; Piliin ang ulo ng martilyo at timbang ayon sa mga kinakailangan ng pamantayan ng pagsubok, and combine the impact hammer; bitay ang martilyo; simulan ang pagsubok, ang martilyo ay malayang mahulog off mula sa na preset taas at epekto sa sample.
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. At the same time, 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.
Obserbahan ang pagputol ng tubo o profile, isa o mas mababa ay nagpapahiwatig na ang epekto paglaban ng pipe o profile ay matugunan sa pamantayan, at higit sa isa ay nagpapahiwatig ng paglaban Epekto pagganap ay hindi matugunan sa pamantayan.
UL 651 Falling Weight Impact Tester offers an apparatus to prevent 2nd strike during testing.
