YAW-10000 Electro-hydraulic servo pressure testing machine

Product introduction
Single rod piston cylinder loading by using YAW-10000 microcomputer controlled electro-hydraulic servo pressure testing machine adopts microcomputer control, multistage hydraulic loading, continuous loading to maintain stable, multilevel test force, automatic collection and storage of data, curve drawing, automatic printing test report, the computer timely control the testing process, test and test curve display simple, reliable, easy operation and high accuracy. The load sensor, servo valve components, so the performance is stable and reliable. This machine is mainly used for testing of metal and concrete specimens compressive mechanical properties, in line with national standards and general technical requirements for testing machines GB/T2611-92> < concrete standard. Complete the test of axial compression deformation. Is the water conservancy and hydropower, colleges and universities, quality inspection center, perfect testing equipment scientific research units and other fields.
Hydraulic system
1. hydraulic principle is the load adaptive feed throttle speed control system.
2. the fuel tank of the hydraulic oil through the motor driven high pressure oil pump into the oil, through the one-way valve, high pressure oil filter, proportional servo valve, into the cylinder. High precision pressure sensor installed in the cylinder, it will force signal into electric signal and transmitting to the computer, the computer acquisition processing converted to force test value is displayed. At the same time, computer according to the signals of the sensors and control procedures for the preparation of issued control signal to the servo valve, control servo valve opening size and direction, so as to control the flow into the cylinder, constant speed load and constant stress, constant displacement, keeping the load, displacement and servo control, the use of air-cooled machine.
