Use:
The Electro-hydraulic servo universal machine uses the stress of hydraulic oil to stretch, compress, curve, and shear the metal plastics, non-metal plastics and composite. The testing machine has the advantage of stable and reliable, high precision and durable use, specially, it is fit for the large loading testing.
The YNS Series testing machines match the KNZ controller which is designed and manufactured by our own company.
Characteristics:
Has wide application, the machine is suitable to test such as tension, compression, bending for metal, non-metal and compound materials with the suitable grips.
The hydraulic fixture is operated by keying and chucked automatically.
Displacement measurement device is designed specially to ensure stable and reliable running and high precision
Measurement resolution is more than ±320000 codes.
Displacement speed could be set discretionarily, also the stress and strain controlling system could be constitute.
The measurement and control system could achieve all operation by computer controlling system with the advantage of fast response, strong timing, stable and reliable.
The servo valve is imported, and having the advantage of high precision and fast response.
The oil source of hydraulic pump is imported, and having the advantage of stable and reliable running, low noise.
The matching software is based on Windows, it could collect and show testing data in a real time, and draw testing curve.
