◆ Brief Description
Used for high-temperature strength testing in accordance with GB/T4338 "Metal Material High-Temperature Tensile Test Method", HB5195 "Metal High-Temperature Tensile Test Method", GB/T2039 "Metal Creep and Rupture Test Method under Tension", and HB5150 "Metal High-Temperature Tensile and持久试验Method".

◆ System Composition
The electric furnace system consists of: high-temperature furnace body, temperature measurement and control system, heating elements, temperature sensing elements, adjustable support arm system, high-temperature tensile clamps and connecting attachments, high-temperature deformation measurement devices, and water cooling circulation system.

◆ Product Overview:
The microcomputer-controlled electro-hydraulic servo universal testing machine operates by sending control signals from a computer to a servo valve, which controls the opening and direction of the valve, thereby controlling the flow rate of oil entering the cylinder. This achieves closed-loop control of constant test force, constant displacement, and other parameters. It is capable of conducting tensile, compressive, and bending tests on metal materials, non-metal materials, product parts, components, structural components, and standard parts. With the addition of an environmental device, this series of testing machines can also perform tensile, compressive, and bending tests on materials in specific environments, such as high-temperature tensile, low-temperature tensile, compressive, and other tests.

1. Main Unit
The main unit features a four-column double lead screw structure with a lower-mounted cylinder, placing the tensile test space above the main unit and the compressive and bending test spaces between the lower beam and the worktable.

2. Transmission System
The lifting of the middle beam is achieved by a motor driving the rotation of the lead screw through a sprocket, adjusting the spatial position of the middle beam and realizing the adjustment of the tensile and compressive spaces.

3. Hydraulic System
Hydraulic oil in the oil tank is pumped into the oil circuit by a motor-driven oil pump, passing through a check valve, high-pressure filter, pressure differential valve group, servo valve, and entering the cylinder. The computer sends control signals to the servo valve, controlling the opening and direction of the valve, thereby controlling the flow rate of oil entering the cylinder and achieving control of constant test force and constant displacement.
