JB-300B charpy impact testing machine pendulum laboratory impact tester for metal
1, Product Reviews
The principle
This company produces the series impact testing machine is strictly according to GB/T3808-2007 "the pendulum impact testing machine products, according to the national standard GB/T229-1994" metallic charpy notch impact test method for impact test metal material.
The test principle of the product is before using pendulum impact energy and impact after the rest of the potential difference between the displayed on the dial, get the test to absorb.

8, Installation and commissioning
1.Split open a case after cleaning, the machine will be moved to the beforehand as a good basis, with adjusting base level 0.2:1000, cement grouting is fixed.After waiting for cement solidification completely tighten the anchor bolts and view level.
2.Check whether each part intact, rotating parts should be flexible.
3.In three phase four wire system 50 hz, 380 v power supply.Insert button box pin socket.
4.Will then display the safety barriers according to the figure pack good appearance.
5.Connect button box on the head and body of reliable connection socket.
6.Put through power supply, and will host the power switch, indicator.
7, the toggle switch in the "on", press the "take place" button, the motor should rotate, electromagnetic clutch should absorb, pendulum should rotate counterclockwise (at this point that the pendulum clockwise, shall be immediately cut off the power and change the power phase) rose to locate position, the motor should be stalling, electromagnetic clutch should release, pendulum by gravity on the hanging rid of institutions.Need shock, first press the "pin" button to make insurance pin returned, and then press the "shock" button, electromagnet for valve electric suction, pendulum fall pendulum impact - automatic pendulum is to hang eyebrow.When need to put a pendulum, hold down the "set" button, electromagnet power cuts, insurance sales return;Electromagnet for valve and electromagnetic clutch and at the same time, the motor rotation, pendulum clockwise rotation, when transferred to the vertical position, release the button lockout.
8.Every time after the shock will be numerical records, and the pointer to the full scale.
9.Check air pointer to return to zero: when the pendulum in the vertical downward stationary position, adjust the position of the plectrum will pointer refers to the 300 (150) J scribed line, inspection level.After take place, impact (don't put impact specimen) pointer should be refers to the zero at the score.
10.Friction loss detection
This is caused by friction energy loss.Pointer and dial needle position, first press the "take place" button, take place to hang place, again according to the "pin" button, and then hold down the "shock" button (or toggle switch set to "off"), the pendulum to go home.When set to the highest position for the first time, with the hand quickly pointer back to the limit position, and to the left of the dial, (be careful not to touch the dial needle and pendulum), for the second time the pendulum to push the pointer to the right side of the dial, then write down the value of the pointer indicated, the difference between the two (the first should be zero) divided by 2, is the impact on the consumption of a swing in the process of friction resistance energy, for 300 joules pendulum energy loss should not be greater than 1.5 joule, for 150 joules pendulum energy loss is not greater than 0.75 joules.

9. Matters needing attention when using
When using the idling running, to check whether the machine is normal.
This machine can choose 300 joules pendulum or 150 joules pendulum, replacing pendulum, need to unscrew the spindle end gland nut, loose with a puller need to change the pendulum, needed to replace the pendulum and tighten the spindle end gland nut can be (but readjust span).
Hammer hooks and the pendulum organization contact length should be about 3-4 mm advisable, (factory has been set, the user don't have to be adjusted).If need to adjust, the location of the mobile hook.
Hammer in the process of Yang pendulum has not yet been hang on hang put institutions when work personnel shall not, within the scope of the pendulum swing activity or work power to avoid accident and dangerous.
On both ends of the shaft bearing factory has come on, use the unit don't have to go.After repair cleaning can add 1, 2 drops of sewing machine oil or watch oil.The rest of the dynamic bearing with vaseline or butter.
Electromagnetic clutch the distance between the two pieces with 1-1.5 mm advisable.Have been adjusted when delivery from factory.Use the unit no longer have to adjust.
Test has been completed, press "set" button, put to the vertical position when the pendulum fall, loosen the "set" button, will play in the "off" toggle switch, then cut off power supply.
