Ao Lai machinery production cement pressure testing machine universal compression testing machine

The cement press adopts a double-station test space, which has the advantages of one machine for two purposes, space saving and simple operation. The electro-hydraulic servo flexural and compressive integrated machine adopts microcomputer control and control modes such as constant velocity test force and test force retention to realize the automatic collection and storage of test data, test curves, and database management functions. It has a network interface and can be L Connect with the Internet. It has the advantages of high precision, good stability, compact structure and convenient operation.

The cement press is mainly composed of body, oil source, computer, servo valve, data acquisition software, high-precision sensor and other Parts.

Test machine installation:

1. Put the hoisting wire rope into the hoisting ring hole when hoisting the test machine.

2. The testing machine is installed on a stable foundation 20 higher than the ground. Two 14 anchor bolts should be pre-embedded, with a center distance of 320mm.

3. When the testing machine is installed, use a 1/1000 frame level to measure the plane of the lower platen to make it level. When adjusting, you can use a shim (the shim point is under the nut under the column) and then fasten the performance to the foundation on. Operation guidance of testing machine:

1. Add 46# anti-wear hydraulic oil to the fuel filler port of the fuel tank to 5 places away from the lower surface of the dipstick.

2. Turn on the power to start the motor (380V 50HZ)

3. Close the oil return valve, turn the handle of the oil delivery valve counterclockwise, and supply oil to lift the piston away from the bottom of the cylinder.

4. Put the specimen, adjust the height of the screw rod, and adjust the specimen to be 1-2mm away from the upper pressure plate.

5. When the upper pressure plate has not been touched for a while, the adjustable fuel delivery valve rises quickly. When the test piece touches the upper pressure plate, the fuel delivery valve is adjusted appropriately to load the test piece until it is crushed.

6. After the test piece is broken, open the oil return valve to make the piston fall back. After breaking the test piece, close the oil return valve and do the next experiment (open the oil return valve at a slower speed).
