Product Overview

The KR‑209B digital‑display hydraulic universal tester adopts a lower‑mounted oil‑cylinder four‑column frame. It executes tensile, compression, bending and shear tests for diverse metallic specimens. With optional auxiliary fixtures, it can also run compression evaluations for non‑metallic samples including plastics, cement and concrete, as well as performance checks for chains, welding rods, tiles and other components. Its compact low‑profile layout makes it well‑suited for engineering‑construction laboratories and on‑site quality‑control stations.

The machine is paired with a standalone digital‑measurement control cabinet. Operators input sample serial numbers and cross‑section dimensions directly via keypad. The unit calculates core mechanical indexes such as tensile strength and yield strength automatically, renders real‑time force‑time curves, stores historical test data and supports on‑site hard‑copy print‑outs.

Core Product Competitive Advantages

1. Lower‑Cylinder Dual‑Working‑Zone Main‑Frame Tensile testing is performed within the upper cavity; compression and bending work take place between workbench and movable cross‑beam. Motor‑reducer, chain and auxiliary lead‑screw assembly drives cross‑beam up‑and‑down travel, enabling fast adjustment of test clearance for specimens of varying dimensions.
2. Mature Manual‑Regulated Hydraulic Circuit Hydraulic fluid passes inlet filter before entering high‑pressure pump. Manual hand‑wheel valves govern oil‑flow direction to drive piston advance and retract. Return‑oil pipelines channel fluid back to the reservoir, delivering steady pressure output for both static‑load and destructive‑fracture test scenarios.
3. Intuitive Digital‑Display Measurement & Control Cabinet High‑precision electronic force‑sensing module feeds readings to LCD screen. Real‑time force‑time curves, current test‑force and peak‑force values are visible, making yield‑point observation straightforward. Operators input sample geometric parameters via physical keys; the system computes material‑property values automatically. Built‑in miniature printer supports quick output of finished test records; historical datasets can be recalled for review.
4. Dual‑Layer Hardware Safety Interlock Overload safeguard: when applied force exceeds 103 % of rated maximum load, the oil‑pump motor cuts off power immediately. Upper‑stroke limit protection shuts down pump power if piston reaches mechanical top‑dead‑center, preventing collision damage to frame and internal components.
5. Complete Interchangeable Standard‑Fixture Kit Standard delivery includes tensile wedge‑grips, compression platens and bending‑test supports. Jaw assemblies cover round‑bar specimens of different diameters and flat samples of varied thickness. Manual clamping comes as standard; automatic‑wedge clamping is selectable for higher‑tonnage variants.

Standard Test Operating Workflow

1. Pre‑Test Inspection & Parameter Entry Check hydraulic‑oil level and pipeline connections. Power‑on the digital‑display control cabinet; input sample ID and cross‑section dimension data.
2. Adjust Test Space & Mount Specimen Run motor‑driven cross‑beam to set proper cavity height. Secure test piece inside corresponding tensile / compression / bending fixture and ensure good axial alignment.
3. Force‑Value Zero‑Calibration Carry‑out force zero‑reset before formal loading to eliminate initial mechanical offset.
4. Manual Hydraulic Loading & Real‑Time Observation Operate manual hand‑wheel valves to regulate oil‑flow and apply load gradually. Observe real‑time force‑time curve on LCD screen, track peak‑force and yield‑point changes throughout specimen deformation process.
5. Record & Print Test Results Once specimen fractures or target load is reached, stop loading. Review measured mechanical‑property indexes on‑screen; trigger print‑out to produce paper test report as required.
6. Machine Shutdown Procedure Retract piston and cross‑beam to home position; remove tested specimen and clean fixtures. Shut‑down hydraulic pump and cut main power supply.
