ASTM D2444 DRKW-112 Pipe drop hammer impact testing machine

Description:

This instrument is the latest test tubing developed and manufactured to ASTM D2444 for impact resistance performance test instruments. It is suitable for PVC-U, PVC-C pipe, PP pipe, PE pipe, underground communication pipeline, for the determination of impact toughness of plastic pipes. It is a ideal test instrument for testing institution, production unit, building materials industry, scientific research. The instrument is suitable for two test methods: pass method and gradient method.

Standards

Complies with ASTM D2444, (Test for Impact Resistance of Thermoplastic Pipes and Fittings by the Drop Weight Method and Act or equivalent test method standards).

Features

1. The hammer lifting device adopts imported AC servo system, two operating speeds, and the high-speed running speed is

12m/min, low-speed running speed is 0.25m/min, test efficiency is extremely high;

2. The unique design of falling pipe and exhaust hole makes the influence of falling air resistance of the hammer body minimal;

3. The lifting height of the hammer body can be set arbitrarily and automatically calibrated;

4. The anti-secondary impact device adopts a unique air cushioning design, which is suitable for the use of different quality hammer bodies

It can be adjusted arbitrarily, no noise, small tremor, long service life of the instrument; Anti-secondary impact capture rate is up 100%；

5. The sample is automatically fixed during the test, which improves the work efficiency and safety;

6. Equipped with combined V-shaped cushion iron, wide test range;

7. Equipped with three-level safety automatic protection device: anti-electric shock protection, hammer chamber door protection and sample chamber door protection,

Effectively protect the personal safety of operators;

8. The host operation panel is equipped with upper and lower limit indications, observation window door not closed alarm indication, sample door not closed

Closed alarm indication, secondary capture device action alarm indication, zero position indication and other safety alarm design.
