KZJ-5000-type electric bending test machine

I. Introduction

Applied to the sand cement for bending strength test is an essential instrument for other varieties of cement and other non-metallic brittle materials such as bending strength testing can also be used to test the instrument.

Second, the main technical parameters

Maximum test force Single lever 1000N Double lever 5000N Indication accuracy ± 1% Single lever output ratio 10: 1 Double lever output ratio 50: 1 Loading speed 50N / s

Third, the structure

Electric bending test machine from the following components (as shown):

1, the main lever ⑻ made of 45 steel plate, the plane engraved with the left end of the scale camel ⑴ inlaid with the focus of the middle knife ⑶ and pivot point ⑷.

2, the screw ⑸ parallel with the main ruler, driven by a reversible motor rotation, so that the camel ⑹ in the main foot on the move.

3, column ⒀ main support role.

4, Vice lever (23) is mainly to make the focus of the knife by the force of the key knife (22) through the upper and lower fixture ⒅ the specimen force, more than the bending strength of cement when the specimen fracture, the main lever on the right Positioning needle on the impact micro-switch ⑾ to stop the motor.

5, under the fixture with hand wheel ⒃ so that lifting screw ⒄ up and down movements.

Fourth, the installation

1, the electric bending test machine unboxing:

(1), open the transport box cover removed plastic film cover.

⑵, remove the main lever, the host and other parts, remove the wrapping paper, do clean dust work.

2, the electric bending test machine installation site environmental requirements:

⑴, electric bending test machine should be installed in a solid table, the indoor temperature Celsius 17 ∽ 25 ℃

⑵, to avoid water vapor, corrosion of gas intrusion.

⑶, the installation of electric bending test machine:

① the main body of the electric bending test machine on the table, adjust the level.

② the main lever assembly mounted on the bracket, mounted on the suspension assembly and vice-lever connected together, the fixed knife block on the baffle, connected to the power supply.

Fifth, the operating methods and rules of use

1, the operation method:

⑴ Turn on the power.

⑵, adjust the zero (adjust the weight mound, so that travel mound in the '0' position, the main lever in the level).

⑶ remove the round surface of the fixture adhesion of debris on the surface of the specimen into the folder fixture, and adjust the fixture to clamp the specimen to produce an elevation of the main lever (the elevation of the size of the specimen storage days and operating experience).

(4) Press the start button light (green) The motor drives the screw to rotate. When the value is added to a certain value, the specimen breaks the main lever. Scale to read the value of flexural strength.

(5) Press the button on the mound (7) to push the mound back to the '0' position to read the value of flexural strength.

2, the use of rules:

After completion of the test, turn off the power and return the mound to the '0' position.

6, electric bending test machine maintenance and troubleshooting;

1, electric bending test machine maintenance;

⑴ electric bending test machine should not have corrosive gases and strong magnetic field environment.

⑵ electric bending test machine with dust cover, with Bi cover to prevent dust intrusion.

⑶ electric bending test machine knife and knife pad should be regularly with anhydrous alcohol ritual wet thick cloth exposed to prevent the blade contact parts contaminated with dust and oil.

2, general troubleshooting;

⑴ start indicator light does not shine, should check whether the fuse is blown.

⑵ electric bending test machine main lever swing is not flexible, should check whether the knife falls on the knife seat V-shaped knife pad in the middle.

⑶ tour mound button failure should check the mound button part of the thread is loose, or spring failure.

Seven, a complete set of electric bending test machine list:

⑴ electric bending test machine main body, the main lever composition, vice-lever components of each group.

⑵ a protective cover.

(1) spare parts ① 1A fuse.

⑷ a product manual.

⑸ a co-certificate.
