Brick folding machine Structure introduction The main components of the machine, hydraulic control, force measurement and display. Vertical Two The column structure, the main structure adopts the welded structure and is effectively treated to ensure the rigidity of the whole machine. Hydraulic cylinder placed Bottom plate On, when the piston is working out After giving Specimen put pressure on , test space (width X length): 420 x 550 Mm. Indenter with high quality Carbon steel (HRC 45 ~ 50) to ensure its service life. Adopt brand Oil delivery and return valve Drive the hydraulic cylinder for the entire test data display Peak planting And test results automatic Print, load speed Manual control , can control the loading rate, the holding time, and the cyclic pressure; Local Have Specimen Break recognition ability. To complete the pair tile of damage Detection . 3. Refer to the instrument manual for details of the force measurement and display operation. Brick folding machine installation 1. When the test machine is hoisted, use a sling to hang on both sides of the beam, or hang it on the two rings on the top. 2. The test machine is installed on a stable foundation 20 cm above the ground. Four M16 anchor bolts should be embedded. 3. When installing the test machine, measure the plane of the lower pressure plate with a frame level of 1/1000, so that it is in a horizontal state. When adjusting, use the horn (the horn pad is under the nut under the column) and then fasten the test machine to the foundation. on. Brick folding machine Operational guidance 1. Add 46# anti-wear hydraulic oil to the fuel filler port of the fuel tank to a distance of 5 cm from the upper surface of the fuel tank. 2. Turn on the power to start the motor (380V 50Hz). 3, put the test piece, with a good block. 4. Tighten the return valve and release the delivery valve. Slowly pressurize and control the speed during the pressurization to prevent overspeed. 5. After the test is finished, loosen the oil return valve (preferably rotate more than two turns), close the oil supply valve, so that the piston will slowly retract (when the piston returns to the original position, stop the machine for the next test), stop the test machine The operation. 6. The safety valve has been debugged at the factory, and do not adjust the safety valve during the experimental operation. 7. The instrument manual describes the operation process of the instrument and is used together. Brick folding machine maintenance 1. The test machine is installed at a clean and dry temperature with no vibration around, and no corrosive gas affects the environment. 2. The test machine should be kept clean to keep the moving parts lubricated and prevent rust. 3. Hydraulic oil uses 46# anti-wear hydraulic oil. 4. The hydraulic oil level of the test machine is within 5 cm from the upper surface of the fuel tank. There is a ruler on the test engine cylinder, and the operator can check it regularly. Brick folding machine Calibration of test machine 1. The test machine is calibrated once a year. 2. The calibration of the testing machine should be carried out under the following conditions: a) Room temperature is carried out in the range of 20 ± 10 °C. b) Relative humidity ≤ 80%. c) There is no vibration in the surrounding environment. d) The power supply voltage fluctuation is less than ±10% of the rated voltage. 3. Preheat the instrument for 30 minutes after the power is turned on, and adjust the zero according to the instrument manual. 4. Start the motor and repeat the calibration after three times of loading to the maximum load. 5. The test machine only performs the relative error of the process indication value and the relative variability calibration. The calibration result should reach: Relative error of indication value ≤±1% Relative variability of indication value ≤ ± 1% Brick folding machine configuration 1, Brick folding Test machine host 1 (including: Main Frame, Cylinder piston, 2 Rigid spacer, force sensor , Manual speed control valve) 2. Control one oil source (including: Controller, Motor oil pump, oil filter , Some tubing) 3, instruction manual, Certificate of authenticity.
