Description
UL 651 Testeur d'impact de poids de chute de tuyaux en plastique
(UL651, ASTM D2444, Max.. impact height 4000mm, adjustable test height, anti-second impact)
Fonctions principales
UL 651 Plastic Pipe 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.
Principe de travail
UL 651 Plastic Pipe Falling Weight Impact Tester is a free fall dropping impact tester.
This UL 651 Plastic Pipe Falling 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.
Installer le tuyau ou le profilé à tester sur l'établi, adjust the height of the sample; sélectionnez la tête de marteau et le poids en fonction des exigences de la norme d'essai, and combine the impact hammer; accrocher le marteau; commencer l'essai, le marteau tombera librement de cette hauteur prédéfinie et aura un impact sur l'échantillon.
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. En même temps, 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 la rupture du tuyau ou du profilé, un ou moins indique que la résistance aux chocs du tuyau ou du profil est conforme à la norme, et plus d'un indique la résistance La performance d'impact n'est pas conforme à la norme.
UL 651 Plastic Pipe Falling Weight Impact Tester offers an apparatus to prevent 2nd strike during testing.
