Brief introduction: Microcomputer-controlled electro-hydraulic servo pressure testing machine is a high precision to do all kinds of mechanical and electrical integration of liquid compressibility test equipment. By the test host, oil source (hydraulic power source), measurement and control system, test instruments of four parts. Think twice about vertical and horizontal hydraulic material testing machine adopts load sensors directly load, compared with the traditional oil pressure sensor indirect way of measuring forces, without considering the gravity of the piston, the influence of friction on the test results. Features: 1. The machine is a closed loop control of electro-hydraulic servo pressure testing machine, with functions of constant stress control and load; 2. Load system consists of load sensor, can fully guarantee the accuracy of the test precision, reliable; 3. The imported low noise high pressure oil pump, can make the workplace has a quiet environment. Air cooling device for the hydraulic system, suitable for continuous work for a long period of time, this series of machine is suitable for the cement, concrete and rock compressive strength test, with the appropriate fixture and measuring device can meet the concrete splitting tensile test, bending test, static elastic modulus test; 4. This series of machine can be widely used in engineering quality inspection, scientific research institutes, colleges and universities, and metallurgical industry; 5. Applicable sample: cement and concrete (70), rock, Technical parameters: Biggest test (kN) : 3000 Press the accuracy level: level 1/0.5 on the Richter scale are unlikely Test force relative error value: + 1% / + / - 0.5% Test force measuring range: 1% - 100% FS (step) 1/450000 of the test force resolution: maximum deformation The distance between the columns (mm) : 440 The distance between the upper and lower platen (mm) : 400 Platen size (mm) : 300 Piston stroke (mm) : 200 The piston displacement speed (mm/min) : 0-80 Test force loading rate (kN/s) : 0.02% 2% FS/s Host overall dimensions (length x width x height in mm) : 720 * 720 * 720 Total power (kW) : 10 Weight (kg) : 3000
