Product Description
microcomputer-controlled electro-hydraulic servo hydraulic universal testing machine adopts the structure of main engine with lower oil cylinder, which is mainly used for tensile, compression and bending tests of metal materials, non-metal materials, product parts, components, structural parts and standard parts.This series of testing machines can also do tensile, compressive and bending tests of materials in this environment if equipped with environmental devices.For example, high temperature tensile test, low temperature tensile test and compression test.Applicable to iron and steel, metallurgy, building materials, quality inspection centers, water conservancy and hydropower, roads and bridges, scientific research institutes, colleges and universities, mechanics and other factories, mining enterprises and testing scientific research institutions.Manufacturing and inspection standards of products1. GB2611 general technical requirements for testing machines2. JJG139 tensile force, pressure and universal testing machineApplicable test method standardsTest operation and data processing meet the requirements of hundreds of standards such as GB/T228 Tensile Test Method for Metallic Materials at Room Temperature, GB/T7314 Compression Test Method for Metallic Materials at Room Temperature and GB/T232 Bending Test Method for Metallic Materials.And data processing methods meeting different standards can be configured according to customer requirements.I. Main technical indicators1 hostThe main engine adopts the main engine with the lower oil cylinder, the stretching space is located above the main engine, and the compression and bending test space is located between the lower beam of the main engine and the workbench.2 transmission systemWhen the middle beam is lifted, the motor drives the lead screw to rotate through the sprocket to adjust the spatial position of the middle beam and realize the adjustment of the stretching and compression space.3. The hydraulic principle of hydraulic system is shown in Figure 2, which is a load-adaptive oil inlet throttle speed regulation system.Figure 2 Hydraulic schematic diagramThe hydraulic oil in the oil tank drives the oil pump into the oil circuit through the motor, flows through the one-way valve, high-pressure oil filter, differential pressure valve group and servo valve, and enters the oil cylinder.The computer sends a control signal to the proportional servo valve to control the opening and direction of the proportional servo valve, so as to control the flow into the oil cylinder and realize the control of constant speed test force and constant speed displacement.4. Electrical measurement and control system:(1) The core components of servo control oil source all adopt imported original devices with stable performance.(2) It has protection functions such as overload, overcurrent, overvoltage, displacement upper and lower limit and emergency stop.(3) The built-in controller based on PCI technology ensures that the testing machine can realize closed-loop control of parameters such as test force, specimen deformation and beam displacement, and can realize tests such as constant speed test force, constant speed displacement, constant speed strain, constant speed load cycle and constant speed deformation cycle.Various control modes can be switched smoothly.(4) At the end of the test, it can be manually or automatically returned to the initial position of the test at high speed.(5) Automatic shifting, zeroing, calibration and saving of physical zeroing, gain adjustment and test force measurement are realized, without any analog adjustment link, and the control circuit is highly integrated.(6) The electrical control circuit refers to international standards, conforms to the electrical standards of national testing machines, and has strong anti-interference ability, thus ensuring the stability of the controller and the accuracy of experimental data.(7) It has a network transmission interface, which can transmit, store, print records and transmit and print data through the network, and can be connected with the intranet or Internet.5.
