ASTM D2444 High precision drop weight impact test machine for
plastic pipe
Summary:
The ASTM D2444 high-precision drop hammer impact testing machine
for plastic pipes is suitable for impact testing of non-metallic
materials such as plastics, glass, ceramics, etc. It is an ideal
testing instrument for measuring the impact strength of materials.
Meanwhile, impact tests can also be conducted on the same materials
or specifications to compare the quality of the materials. It is
applicable to both transfer method and gradient method.
Meet criterions:
ASTM D2444, ISO4422, ISO3127, BSEN1411 and BSEN744.
The characteristics of the equipment:
Third level protection:
●First level sample cabin door safety protection;
●Secondary observation window door safety protection (not added
temporarily);
●Third layer upper and lower limit safety protection.
Rapid improvement:
Using a high torque stepper motor, the lifting speed can reach
250mm/second, and the fastest time from zero to 2 meters is 8
seconds.
Intelligent hovering:
This machine adopts a multi-level speed regulation program to
ensure that the hammer head stops smoothly and the control position
has no deviation.
Exhaust pipe design:
The drop hammer pipe adopts 3D modeling to increase exhaust holes
and reduce wind resistance. At the same time, the maintenance
structure of the pipeline has been increased to prevent damage and
deformation of the pipeline.
Pneumatic capture hammer, pneumatic release hammer:
Abandoning traditional electromagnetic hammers and iron hammers,
adopting pneumatic structures with larger force values, using a
300N long stroke dual cylinder hammer head, and a cow tendon plate
hammer surface, the hammer head is stable and undamaged; The hammer
head also adopts a pneumatic structure, fundamentally solving the
problems of cable bending and leakage. Pneumatic adopts a pneumatic
automatic locking structure, which is safe and reliable.
Integration and modular assembly:
The mechanical part adopts a standard aluminum alloy profile
assembly structure, while the electrical part adopts a 7-inch touch
screen and Delta PLC, achieving the characteristics of standardized
process, modular installation, light structure, and high strength.
Outstanding quality:
All equipment used is imported, with Adker brand cylinder, Delta
brand touch screen, Delta brand PLC, and Taiwan Mingwei brand power
supply. All electrical, mechanical, and software components have
safety measures in place. Such as anti leakage, anti short circuit,
anti static, anti-interference, anti leakage, anti power outage,
anti misoperation, etc.
High degree of automation:
This instrument can automatically grasp the zero point, perform
automatic hammering, automatic hammering, and automatic testing.
