Electrical casing impact teste

  Electrical bushing impact tester Plastic pipe impact testing machine casing impact testing machine I
Introduction to electrical casing impact testing machine
It is applicable to the impact test of various plastic pipes and plastic bellows to determine the stamping energy required for pipe damage, so as to determine its stamping strength, which meets the requirements of GB / t14823 2 conduit for electrical installation special requirements & mdash; rigid insulating material flat conduit, jg3050 insulating electrical bushing and accessories for building, zbg33008 PVC plastic corrugated wire pipe and other requirements

Because of its simple structure, convenient operation and reliable performance, it is more and more widely used

3、 Structure description of electrical casing impact tester
  It is composed of base, column, guide rod, hammer and hook

4、 Operation of electrical casing impact tester
1
Place the electric testing machine stably, and put an offset plate under the base

2
Wipe the impact tester clean, and inject thin oil into the column and guide rod

3
Loosen the confinement screw, lift the guide rod, place the hammer on the hook, and then place the spacer steel block at the bottom of the guide rod

4
Place the sample on the backing plate and contact the spherical part of the spacer steel block with the highest point of the sample

5
The scale of 0 and 300 mm is round, and all the scale of 0 and 300 mm are round

After the 0 scale mark is flush with the upper part of the spacer steel block, tighten the fastening screw

6
Loosen the stop screw, move the beam so that the bottom of the hammer is flush with the scale mark of the required height, and then tighten the stop screw

7
Press the two hooks at the same time to make the hammer fall down and impact the sample through the spacing steel block

8
Lift the spacer steel block, take down the sample and observe whether there is crack or damage

9
After the test, the hammer, base plate, spacer steel block and other parts shall be wiped clean and stored in a dry place
Do not impact without sample
