1.Description Chase friction testing machine is used to evaluate the frictional characteristics of material in braking system in accordance with the SAE J661,GB 5763-2018 and GB/T 17469-2012. Chase machine is suitable for small bench test of M1, M2, N1, O1 and O2 vehicles brake linings. This machine is widely used for product formulation R&D, Quality control and Certification etc. 2.Principle A constant pressure is applied to the sample,which will be pressed against the inner surface of the friction drum which rotates at a certain speed, so a friction force will be generated along the tangent direction of the contact surface. The friction coefficient of the tested sample can be determined by measuring the pressure and friction force. During the test, the Chase friction tester controls the temperature change at any time according to the requirements. The drum outer ring is used to assist the heating tube heating and the back suction cooling, so that the temperature change at the sample is stable and the temperature measurement accuracy is higher. 3.Features (1)Loading by Pneumatic servo with high precision control. (2)Temperature of friction drum is adjustable to adapt to different test requirements and different climatic condition. (3)Rubbing speed can be set freely between 0 and 1000 RPM. (4)The maximum load is up to 2000N. (5)This machine is controlled by PC. Speed, loads, temperature and test time can be preset by software. Test results are saved in computer. 4.Standards SAE J661, SAE J866, GB 5763-2018, GB/T 17469-2012, 5.Specifications Speed 0 to 1000 RPM Load 0 to 2000 N Temperature 0-600 (1112) Heating power 6KW Friction drum Ф277mm Power AC 380V Weight Approximate 2100kg

Scratch Grinding Tester Automobile line inspection equipment Wire and Cable Detection Equipment It is applicable for assessing the scratch-resistant performance of automobile wire insulation with external forces in line with the requirements of GB/T12528-2008. Main parameters: 1. The scratch grinding device exercises in two directions along wire axes with a stroke above 10mm 2. Exercise frequency: 50~60 cycles/min 3. Minimum distance between test points and test point and test sample end: >10mm; rotation angle of test sample: 90° 4. Length of test sample: Test sample which is about 750mm is firmly fixed to a steel anvil 5. Weight: 400, 700, 1000g (weights applied to scratching needle) 6. Function: The device will stop when the scratching needle grinds through insulation and comes into contact with conductor
Purpose SYQ61 concrete strength tester is used to test compressive strength of concrete by two ways: rebound and ultrasonic-rebound method. Also, it can be used to test sound time and speed in concrete. Specification Technical specification for inspection of concrete compressive strength by rebound method (JGJ/T23-2011) Technical specification for detecting strength of concrete by ultrasonic-rebound combine method (CECS02:2005) Performance 1. Multi-function for testing compressive strength of concrete. It is used to test the compressive strength of concrete by rebound method and ultrasonic-rebound method. 2. Get the compressive strength value of concrete by ultrasonic-rebound method in one instrument. It need two instruments usually, one to test sound speed in concrete, the other to test rebound value. 3. Can save test date. This is convenient for laborer data management. 4. Real USB transmission. Data can be transmitted to computer for future process and analysis. 5. Powerful data process and analysis software in windows. Test data can be export to word or excel for future process and analysis. Technical Data 1. Permissible sound time error: +/- 0.1µs 2. Sensor frequency: 50KHz 3. Rebound kinetic energy: 2.207J 4. Rebound springs Rigidity: 785.0+/-40.0(N/m) 5. Rebound bar impact length: 75.0+/- 0.3 mm 6. Rebound value permission error: =< +/-1 7. Average rebound value on Calibration anvil: 80+/-2 8.
