universal hydraulic compression testing machine
Product Description
Structure introduction
universal hydraulic compression testing machine is mainly used to execute the tension, compression, bending, shearing etc. test for metal materials. Attached simple accessories and devices, it can be used to achieve many kinds of mechanical performances.
The oil cylinder is at the bottom of the load frame, tension space is at the upside of the load frame, compression and bending space is between lower cross head and working table. The lower cross head is driven by motor through decelerator, chain transmission device and screw pair, so realize the adjustment of testing space.
The universal hydraulic compression testing machine adopts oil pressure transducer to measure load, use computer control display load,

FAQs of Universal Hydraulic Compression Testing Machine:
Q: How does the Universal Hydraulic Compression Testing Machine improve material testing accuracy?
A: The machine uses a precision load cell and hydraulic Class 1.0 accuracy pressure gauge, ensuring results within 1% of the indicated load. Its microprocessor-based control panel and digital LCD display provide real-time feedback, making data collection both detailed and reliable.
Q: What is the process for conducting a compression test with this machine?
A: Place the specimen on the 250 mm x 250 mm working table, select manual or automatic mode, and initiate the loading sequence. The hydraulic system applies controlled pressure, while the digital display shows the applied load. Data can be logged via USB or RS232 ports throughout the process.
Q: When should the pressure relief valve be used during operation?
A: The pressure relief valve automatically engages in case of overload or excessive pressure, protecting both the operator and machine. Operators should ensure the valve is functional before each test to maintain safety standards.
Q: Where can this machine be installed for optimal operation?
A: Install the machine in a laboratory or construction testing facility with ambient humidity below 80% and temperatures between +5C and +45C. It requires stable, level flooring and access to an electric power source (220V/380V AC, 50 Hz).
Q: What materials can be tested using this hydraulic compression machine?
A: The machine is designed for testing the compressive strength of concrete, bricks, cement, and various construction materials. Optional models provide load capacities up to 3000 kN, accommodating a wide range of specimen sizes and types.
Q: How does data output and logging work on this machine?
A: The microprocessor-based control panel supports real-time data output via USB or RS232 ports. This enables convenient data logging, transfer, and analysis, facilitating compliance with quality assurance and certification standards.
Q: What benefits does the four-pillar rigid frame offer?
A: The four-pillar rigid frame enhances structural stability and load distribution, minimizing mechanical deformation during high-pressure tests. This ensures more consistent and repeatable results, which is vital for laboratory and industrial applications.
