Falling weight impact tester JJICI

for pipesthermoplastic pipetube

This instrument is used to test the impact resistance of plastic manhole base and wellbore wall. It is a necessary testing instrument for plastic manhole testing institutions, production and construction units. Features 1. Unique modular design, mainly including sample support base, lifting device, protective tube drop hammer device, power system, control unit; 2. Using the principle of vacuum lifting hammer, the suction power is large and the efficiency is high. The hammer falls freely, impacts the sample, catches the hammer in time after impact, and raises the hammer to the impact height at high speed to prevent secondary impact to the sample; 3. Cantilever type liftable structure design, with open test space, convenient for sample installation. Before the impact, the falling hammer is absorbed in the protective tube and extends along with the protective tube to the middle of the flow trough at the bottom of the inspection well. After the protective tube is positioned, press the impact button to freely fall the falling hammer. After the impact, the impact hammer is automatically captured in time. The impact hammer is again absorbed in the protective tube. After the test is completed, the protective tube is raised, and the operation process is safe and reliable. During the flow trough impact test, the applicable inspection well base diameter range: 315mm～Ф1600mm; 4. The protective tube is installed vertically, the inner wall roughness is less than 0.8, the friction is extremely low, and the falling weight speed is not less than 95% of the theory;
