FAQ
Q1: What are the main differences between the YYW-SS series and ordinary pressure testing machines?
A: The core difference lies in its electro-hydraulic servo closed-loop control system and dual-pump technology. Compared to ordinary models, it not only has higher testing efficiency but also achieves constant-rate stress control, meeting higher standards of scientific research needs.
Q2: Are there any special requirements for the laboratory environment for this equipment?
A: It is highly adaptable. Thanks to advanced servo hydraulic technology, it operates with extremely low noise (ultra-low decibels), and some models can use 220V power, making it ideal for modern laboratories with high environmental requirements.
Q3: Will the explosion-proof safety net affect the observation of experiments?
A: No. The safety net is made of a high-transparency material, which not only protects personnel from debris during sample breakage but also allows researchers to directly and clearly observe the sample's destructive process.
Q4: How is the equipment guaranteed to maintain accuracy over long-term use?
A: In addition to using high-precision sensors, its integral cast body structure provides extremely strong resistance to deformation. Combined with precision machining processes, this hardware ensures long-term force accuracy and stability.
