Weight: about 5000kg four test normal working conditions 1, ambient temperature: 10-35 ℃ Humidity: ≤80% 2 Power: 3-phase 380V ± 10% 50Hz 3, no strong vibration, corrosive media, no strong electromagnetic interference environment 4, computer power: 220V ± 10% 50Hz access to five separate main structure (I). Host: The host is horizontal carrying frame by four carrying frame guide support bars and the middle, both ends fixed beam composed constitute the main part of the host, loading cylinder (tension-type jack) and hollow sensors are attached to the carrying frame The outer ends of the anchorage component is detected by flat plate and strand anchors fixed to the outer ends of the host, the work load cylinder through the strand to be applied to detect anchor component test force. Host main components as follows: 1. The guide support bars: a total of four, with 45 # carbon steel raw material steel or forged steel processing, are fixed at both ends and an intermediate portion connected to the fixed beam components during the test are carried The major components. 2. The fixed beam assembly: divided into left and right in the middle of two and one blank ductile iron processing, are fixedly connected to the four corners of the guide support bar nut. In which the left and right outer ends of the sensors and the cylinder piston pair. 3. cylinder piston vice: the YCW-650B-type tensioning jack, high pressure feedthrough can withstand> 50MPad pressure for the sample is applied loads, piston stroke is 200mm. The clamp assembly: the flat anchor plate / N hole plate and anchorage components, including flat anchor plate / N hole plate processing using steel forging blank, and then quenched by the heat treatment process, to ensure that deformed under the minimum amount of force. 5. protection components: two protective nets and mobile gear sand wall in two parts. Protective nets using steel and metal fabrication, mounted on the upper and sides of the computer, there are left and right combination, to prevent the strand force if a single strand disconnect wounding. Mobile block sand wall with welded steel manufacturing, the inner end affixed to slow the impact of rubber, the lower part is equipped with moving wheels to prevent the strand force if a single shot wounding disconnected from both ends. (B) high pressure servo-hydraulic servo-hydraulic source Source main task is to master cylinder according to the rate of the test requirements and fueling operations master completed the testing process, the hydraulic pressure source main components as follows: 1. Housing: 3mm cold-rolled steel plate produced by the , after the completion of a number of surface treatment processes. 2. The pump motor group: the ultra-high pressure radial piston pump and composed of three-phase asynchronous motors, as the hydraulic system for the high-pressure systems, so the pump must be equipped with ultra-high pressure pump output, this machine is equipped with the use of ultra-high pressure radial pump Germany FAG's patented technology to produce; use 1.5kw three-phase asynchronous motors with matching and as a power source. 3. EHV digital servo valve: most of the control valve is a high pressure, can withstand the pressure from the valve body and the permanent magnet motor formed, receiving the pulse signal issued by the controller to drive permanent magnet motors do stem angle rotation, in order to achieve the fuel into the regulation, so that the servo control testing machine. The solenoid valve: the three-way solenoid valve, piston master cylinder for use commutation. 5. Oil filters: electro-hydraulic servo testing machine with a dual-stage filtration mode, which uses a replaceable cartridge filter level, it can filter out the> 10μm particle impurities, ensure that the control valve is working properly. 6. Fuel tank: a container for storing the hydraulic oil tank of the hydraulic source volume of about 120L. 7. relief: mainly used for pressure protection, when the pressure in the hydraulic system exceeds the pressure setting of the relief valve in the spring is the top, part of the ultra-high pressure hydraulic oil will spill out and cause along the line back to the tank. 8. piping systems: a hydraulic source said connecting portions of the components, using high pressure seamless steel pipe production, the joint use of card sets. 9. Electrical drag part: ensuring strong electric part of all electrical and safety systems work properly and, mainly by air switches, relays, exchanges and contacts, electric power supply and other components, mounted on the upper side of the hydraulic pressure source. Hydraulic power source is part of the test machine work, oil pump high-pressure hydraulic power units oil through the oil filter into the digital servo valve, after the governor control system into the working cylinder, after the completion of the testing process by reversing solenoid valve, Pistons Back Pre-work state. Can also be installed according to the air-cooled chiller test requirements for mandatory protection of oil, also equipped with an oil surface indicating devices. Through the above means ensures the hydraulic system a long time stability.
