The machine adopts double oil cylinder, the control precision, the measurement precision is high. The hydraulic oil in the oil tank drives the high pressure pump into the oil circuit through the motor, flows through the check valve, high pressure oil filter, differential pressure valve group, servo valve, and enters the oil cylinder. The computer sends a control signal to the servo valve to control the opening and direction of the servo valve, so as to control the flow into the cylinder and realize the control of the constant speed test force.
1.Using high-precision amplifier and A/D converter, the whole process is not divided, real-time display of load, peak value, loading speed and intensity.
2.PID closed-loop control strategy is used to realize constant speed loading, and the loading curve is displayed in real time.
3.Automatic interval timing and continuous testing.
4.Query and print test results flexibly and conveniently.
5.When the test force exceeds 3% of the maximum test force, overload protection, oil pump motor shut down.
Our company has successively obtained ISO9001 certificate, CE certificate, electro-hydraulic servo pressure testing machine, electro-hydraulic servo universal testing machine, electronic universal testing machine and other types of testing machine type evaluation certificate, and the member of the national steel structure industry association.
With the spirit of honest and unsophisticated craftsman, patience, perseverance, and original heart, we are striving for excellence and creating excellence. Customer first is our service concept; Learning, service, unity, wisdom and dedication are our corporate culture; Creating and building a well-known brand of testing machine in China and even the world is our ultimate pursuit. We firmly believe in, stick to and strive for it. At the same time, we are willing to lead the development of the company, and contribute to the development of the testing industry in the motherland and the world.
1. Are you a manufacturer?
