The YYW-DS series testing machine, developed by Zhejiang Yiyu Instrument Equipment Co., Ltd., is a high-end mechanical testing device specifically designed for construction engineering, research institutes, and industrial testing. It employs advanced electro-hydraulic servo technology, providing extremely high-precision force control and a stable testing environment.
Core Testing Functions
- Multi-material Coverage: This series is primarily used for compressive strength testing of cement, concrete, and rock.
- Extended Testing Capabilities: Equipped with specialized fixtures, the equipment can also perform splitting tensile strength, flexural strength, and static modulus of elasticity testing of concrete.
- Precise Control Mode: Features closed-loop force control, equal stress control, and load holding functions, ensuring the testing process fully complies with national and international standards.
Superior Structure and Power System
- High-Rigidity Integral Casting: The main unit adopts an integrated high-strength cast structure, precision-machined to achieve extremely high rigidity and stability, ensuring reliable data even under high-load testing.
- Innovative Dual-Pump Technology: Equipped with unique dual-pump technology (including a large-displacement auxiliary gear pump), significantly improving testing speed and work efficiency, making it particularly suitable for long-term, high-intensity continuous operation.
- Environmentally Friendly and Energy-Saving Drive: The hydraulic system is driven by a servo motor and a radial piston pump, resulting in extremely low operating noise (ultra-low decibels) and significantly reduced oil temperature rise. The equipment only requires 220V household electricity to operate, making it more energy-efficient and environmentally friendly.
Intelligent Interaction and Operation
- High-Definition Touchscreen Interaction: The machine integrates a 17-inch touchscreen industrial computer with a proprietary SmartTest interface, providing a smooth and intuitive operation.
- High-Standard Measurement Hardware: Utilizes a 0.5-grade high-precision load sensor, ensuring measurement accuracy, excellent repeatability, and long-term stability.
Safety Protection Design
- Visible Explosion-Proof Net: The front of the equipment is equipped with a transparent explosion-proof safety net. This design provides excellent experimental observation visibility while ensuring operator safety and preventing sample splashing.
FAQ
Q1: What are the practical benefits of the "dual-pump technology" in the YYW-DS series?
A: Dual-pump technology, through the collaboration of a large-displacement auxiliary pump and a precision-controlled pump, enables rapid movement during non-testing phases and precise loading during testing phases. This significantly shortens the testing cycle for a single sample and substantially improves the overall efficiency of the laboratory.
Q2: Does this equipment have special requirements for the power supply environment?
A: No industrial high-voltage electricity is required. Thanks to the efficient servo control system, this series of equipment (including the large 3000kN model) can operate stably with only a standard 220V household power supply, significantly reducing laboratory power wiring costs.
Q3: What standard concrete tests can it perform?
A: Besides standard compressive strength testing, it can also perform splitting tensile strength testing, flexural strength testing, and complex static modulus of elasticity testing on concrete, making it a very comprehensive pressure testing platform.
Q4: Is the hydraulic system very noisy?
A: No. The system uses servo motor drive technology, resulting in extremely low noise levels, creating a quiet and efficient working environment for laboratory personnel.
