First, TYE- 2000 B pressure testing machine is mainly used to test the compressive strength of concrete, stone, cement, refractory brick and other building materials. With the measuring instrument of elastic modulus of concrete, it can also be used to measure the elastic modulus of concrete specimen under static compression. By using hydraulic transmission, electronic force measurement and digital display, it has the characteristics of compact structure, convenient operation and high precision of force measurement. 1, basic technical parameters: bearing capacity (0 ≤ 1000) kN, (0 ≤ 2000) kN indication relative error ±1% motor power 1.1kW piston stroke 50mm power 380V 50Hz 2, main specification: net distance from upper and lower pressure plates to 320mm upper and lower pressure plate dimensions (320 × 320) mm shape size (length × width × height) (796 × 435 × 1325) mm net weight 785kg II, structure and working principle brief introduction (1) structure: this machine is mainly composed of the following three parts (Fig. 1): 1, the body part of the rack 3 is a strong frame of nodular cast iron, the upper part of the rack is equipped with nuts 4, connecting wire Bar 2, there are convex ball seat 5 and upper pressure plate 6 at the end of the wire rod, and the contact between the upper pressure plate and the compression surface of the specimen can be automatically adjusted when the specimen is pressed. According to the size of the specimen, you can turn the hand wheel 1 to adjust the screw to the appropriate height. The surface of the lower bearing plate is engraved with a positioning line, which is convenient for the specimen to be placed in the center position. The lower bearing plate 7 is placed on the piston 8 and the dust shield 10 is installed under the lower pressure plate to prevent debris and debris from falling into the cylinder 11. When the piston is raised by oil pressure, push the lower pressure plate upward and top the specimen. The 11 seats of the cylinder are located in the lower part of the frame, and a composite sealing ring 9 is embedded in the upper part of the inner wall of the cylinder to prevent At high pressure, the oil between the piston and the cylinder spills, and the oil overflow loss is very small. There is a spill pipe on the upper left side of the rear of the cylinder, which directly allows the oil spill on the cylinder to flow back to the tank, so it can keep the machine clean around the machine. If the concrete compression test is carried out, it is suggested that the user can make a inclined bucket and tilt to the back side in order to remove the fragments. In order to prevent the specimen from moving away frequently, it is suggested that the gasket suitable for the size of the specimen should be made, but the gasket suitable for the specimen size should be heat treated (hardness HRC55 above) and easy to replace after long wear. 2. Hydraulic control system includes motor and high pressure oil pump, oil supply valve, return valve, fuel tank and so on. The oil pump and motor 14 are connected by coupling and are mounted on the fuel tank 13. The high pressure oil enters the oil supply valve 16 directly. When the oil supply valve is closed, the oil flows back to the fuel tank directly. When the oil supply valve is opened and the return valve 15 is closed, the high pressure oil enters the cylinder and transmits it to the sensor. The sensor transmits the signal to the force measuring instrument 18.3. The force measuring system is composed of hydraulic sensor, signal amplifier converter, data processing, printer and control operation panel, transmission loading mechanism and so on.
