Product Overview

The KR‑214A digital electro‑hydraulic compression‑bending tester is a bench‑style hydraulic‑loading laboratory instrument tailored for construction‑material mechanical‑performance evaluation. It performs compressive‑strength testing for bricks, rock samples, cement mortar and concrete blocks. Equipped with optional bending‑test attachments, the unit can also complete flexural‑strength assessment for building‑material specimens.

This machine combines manual‑adjustment hydraulic drive with digital electronic data acquisition. The front‑panel digital display shows real‑time loading magnitude, loading‑rate and peak force readings. It integrates peak‑value hold, data memory and overload interlock protection functions. It is widely adopted by cement plants, brick‑and‑tile manufacturers, highway‑bridge engineering laboratories, civil‑engineering teaching labs and third‑party building‑material quality‑inspection agencies.

Core Product Competitive Advantages

1. Stable Manual‑Regulated Hydraulic‑Oil Circuit Hydraulic oil passes through intake filter before entering the high‑pressure pump. Operators adjust two hand‑wheel valves to control oil‑flow direction, driving piston advance and retraction. Return‑oil flows back into the oil tank. The whole hydraulic system delivers steady pressure output, suitable for destructive compression‑break tests of brittle building‑material specimens.
2. Intuitive Digital Measuring & Display Unit High‑precision force‑sensor captures load signals; digital panel directly presents real‑time force values and peak‑load data after sample failure. The peak‑hold function locks the maximum force reading automatically, facilitating quick on‑site record‑taking without computer support.
3. Dual‑Purpose Compression‑and‑Bending Capability Multiple configuration options are available: pure compression‑test version, bending‑only variant, and combined compression‑bending integrated model. The bending‑test assembly includes bending rollers with adjustable center distance, to meet flexural‑strength test requirements for cement and rock specimens.
4. Reliable Hardware‑Level Overload‑Protection When actual test force exceeds 103 % of full‑scale rated capacity, the system triggers protection logic and cuts off hydraulic‑pump motor power supply immediately, preventing frame, piston and sensor from overload‑caused damage.
5. Compact Integrated Cabinet‑Type Structure All hydraulic power components are housed inside the lower cabinet, saving lab bench‑space. Standard hardened compression platens and bending‑roller assemblies are supplied, requiring minimal assembly work upon delivery. Operation learning threshold is low for workshop‑site laboratory staff.

Compression‑Strength Test Procedure

1. Pre‑Test Check: Inspect hydraulic‑oil level and pipeline sealing. Power‑on digital‑display control unit and confirm zero‑point status.
2. Specimen Placement: Position brick / cement‑cube / concrete sample centrally on the lower compression platen, ensure good vertical alignment.
3. Manual Loading: Rotate operating hand‑wheels to drive piston upward and apply compression load steadily. Observe real‑time force‑value changes on digital screen.
4. Record Peak Data: After specimen crushing, the display holds peak‑force value; document the reading.
5. Reset & Clean: Retract piston to home‑position, remove broken sample debris and clean platens.

Bending‑Strength Test Procedure

1. Install bending‑test roller assembly and adjust roller center‑distance according to material‑test‑standard.
2. Lay specimen horizontally across lower supporting rollers, keep centered placement.
3. Operate hand‑wheels for slow loading until specimen fractures, record peak bending‑failure force.
4. Retract piston, remove damaged specimen and tidy‑up fixtures.
5. Equipment Shutdown Steps After finishing all sample batches, retract piston fully, clean platens and rollers. Switch off display unit and cut main power supply.
