  • Servo Hydraulic Fatigue Test Machine
    1.Certification: ISO,CE
    2.Dynacell load cell feature compensation
    3.Wide range of grip

    1. Name of Equipment: Servo Hydaulic Fatigue Testing Machine

    2. Model of Equipment: PLW-300

    Product feature

    (1) Sampling and control frequency stability, to ensure the products have the security protection function

    (2) Low level, super temperature, filter jams,, overload, preset fatigue characteristics such as number;

    (3) The product has remote pressure regulating functions, so as to facilitate the energy saving;

    (4) The non-contact displacement sensor, no wearing, and need not to calibration;

    (5) The displacement sensor MTS, absolute position measurement, resolution as high as 0.001 mm;

    (6) Load measurement using Interface fatigue special sensors, high precision, long life, up to 100 million times;

    (7) Fully enclosed hydraulic source and reduce noise;

    (8) Using digital DOLI controller, high control accuracy;

    (9) Digital controller, synchronous channels collection technology, eliminate phase difference;

    3. Introduction

    The main frame adopts double pillar single space structure, the base, actuators, pole, can ensure that stretch, compression fatigue test of the special hydraulic chuck, high precision load sensor and with hydraulic lock device no clearance can move beams etc. The hydraulic lifting, lowering beams, with hydraulic lock function, easy to positioning, lock reliable, easy to operate. Beam position in 50 ~ 600 mm range any adjustments. The actuator try platform, oil cylinder integration design, high rigidity, more traditional modular cylinder, leakage link less, more wear and stiffness higher. Hydraulic collet tight force big, holding fast, reliable, can meet the stretch to compression test force zero test requirement that stretch, compression cycle fatigue test. Displacement measurement using LVDT sensor measuring non-contact, measured accurately, long service life.

    Hydraulic source by tank, and a high pressure oil pump motor, electromagnetic valve and integrated valve piece, cooler, relief valve, pressure gauges etc. The hydraulic fountain without leakage technology, in any working environment and working status, no oil leaked and drip; The hydraulic source down noise technology, reduce the operating noise; Servo oil source can be installed in a single pump room inside, such noise will not to test indoor.

    Servo oil source cooling water used as a way to reduce the oil temperature.
