WAW-2000F Microcomputer controlled electro-hydraulic servo universal testing machine

Technical prescriptions

1. Brief introduction

WAW-2000F Microcomputer controlled electro-hydraulic servo universal testing machine, mainly used for metal, non-metal tensile, compression, bending and other tests. Applicable to metallurgy, construction, light industry, aviation, aerospace, materials, colleges and universities, scientific research units and other fields. The test operation and data processing conform to the requirements of GB/ t228.1-2010 "tensile test of metallic materials - part 1: room temperature test method".

2. Description of the project

2.1 Main engine

The main engine adopts oil cylinder undermounted main engine, the stretching space is located above the main engine, and the compression, bending and shearing test space is located between the beam and the workbench under the main engine.

2.1.1 The host framework

Oil cylinder lower, four column two screw form, low center of gravity, stable and reliable main engine.

2.1.2 Beam

Half - open clamp holder, high strength, no deformation, suitable for steel mill to steel specimens such as the large workload of stretching.

2.1.3 A liner is arranged between the clamp clamp plate and the clamp holder, Effective protection against wear and tear.

2.1.4 Weight-Main Unit

High stiffness, high safety factor, durable.

2.1.5 The lower beam is provided with a chip discharge hole, Easy to remove sample debris, easy to wipe maintenance equipment.

2.2 Drive system

The lower beam lifting adopts motor and reducer sprocket chain transmission to drive the screw to rotate, so as to realize the adjustment of stretching and compression space.

2.3 Hydraulic system

The hydraulic principle is shown in figure 2, which is the load adaptive oil intake throttling speed regulating system.

The hydraulic oil in the oil tank drives the high-pressure oil pump into the oil channel through the motor and flows through the one-way valve, high-pressure oil filter, differential pressure valve set and servo valve to enter the oil cylinder. The control software sends the control signal to the servo valve and controls the opening size and direction of the servo valve, so as to control the flow of hydraulic oil into the cylinder and realize the closed-loop control of test force and displacement.
