1. Introduction
WAW-600B microcomputer-controlled electro-hydraulic servo universal testing machine host adopts a cylinder-mounted host, which is mainly used for metal and non-metal tensile, compression and bending tests. It is suitable for metallurgy, construction, light industry, aviation, aerospace, materials, colleges and universities, research institutes and other fields. The test operation and data processing meet the requirements of GB228.1-2010 "Metal Tensile Test Method for Room Temperature Materials".
Two, system overview
1. Main engine: The main engine adopts the under-cylinder engine, the tensile 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 system: The lower cross beam is raised and lowered by a motor driven by a reducer, a chain transmission mechanism, and a screw pair to realize the adjustment of the tension and compression space.
3. Hydraulic system: The hydraulic oil in the oil tank is driven by the motor to drive the high-pressure pump into the oil circuit, flows through the one-way valve, high-pressure oil filter, differential pressure valve group, servo valve, and enters the oil cylinder. The computer sends a control signal to the servo valve to control the opening and direction of the servo valve, thereby controlling the flow into the cylinder, and realizing the control of constant velocity test force and constant velocity displacement.
4. Safety protection: When the test force exceeds 3% of the maximum test force, overload protection and the oil pump motor stop. When the piston rises to the upper limit position, the stroke is protected and the oil pump motor stops.
6. Attachment: A full set of attachments include: extension attachment, compression attachment, and bending attachment.
7. Others: Please refer to the accompanying technical documents for the instruction manual, certificate, packing list, etc.
