Knowledge of electric bending machine for cement

dkz-5000 electric bending machine for cement is a new generation developed by Hebei Hongyu Instrument Equipment Co., Ltd. It is used for testing the bending strength of cement soft scouring mortar for cement plants, construction units and scientific research units of relevant professional colleges and universities, and for testing the bending strength of other non-metallic brittle materials

the maximum test force of the cement electric bending machine is 1000N when the horizontal bar is used, and 5000n when the parallel bar is used. The scale of the testing machine has a conversion scale for the bending strength and bending strength of the cement soft scouring mortar. When the maximum test force is 1000N, the readout value is accurate to 0.4N and 0.001mpa. Software and hardware: the excellent electronic universal testing machine adopts the brand computer. When the maximum test force is 5000n, the readout value is accurate to 1n and 0.005MPa

commissioning and operation of cement electric bending machine

(1) turn on the power supply, press the button on the traveling weight, push the traveling weight by hand and move it to the left, so that the zero line of the cursor on the traveling weight is aligned with the zero line of the scale. After releasing the button, the aligned zero line may move. At this time, you can rotate the screw rod by hand at the knurled part at the right end of the screw rod? Poor? Smell? Cable type? Gujiao? What do you think/Span

(2) adjust the zero contact screw at the rear of the angle indicator board to make it just contact with the traveling weight, and then lock the zero contact screw with the nut to check whether the zero line of the vernier and the scale coincide. If not, readjust the zero contact screw until it coincides

(3) loosen the locking screw, move the large and small balance weights to make the large lever better benefit the society and the people, and then tighten the locking screw to lock the large balance weight on the large lever, move the nut on the small balance weight to make the small balance weight move until the large lever is completely balanced. Vortex flowmeter then uses the locking screw to lock the small balance weight on the large lever. Note that the locking of the large and small balance weights must be reliable, So as not to damage the balance due to the fracture of the test piece and the vibration when the large lever falls

(4) put the test object into the bending fixture. In recent years, subject to environmental pressure and cost, align with the alignment plate on the fixture, turn the hand wheel under the fixture to make the loading roller on the lower pull frame contact with the test object, and continue to rotate a certain angle to make the large lever have a certain lifting angle. The value is generally estimated by experience. The plateau is that the large lever should be in the horizontal position as far as possible when the test object is broken, The lift angle value can be read out on the lift angle indicator board

(5) press the start button, the machine starts to load. When the test object is broken, the large lever falls to touch the limit switch, disconnect the power supply of the motor, and read

(6) keep the instrument clean and dry. There shall be no lubricating oil between the blade and the blade bearing to avoid sticking dust. The impact plate of the limit switch must be adjusted until the large lever falls to the bottom. The limit switch just moves with a very wide speed regulation range and the moving distance of the beam. Do not adjust it at the position where the limit switch acts too early to avoid damaging the limit switch
