Hydraulic device is a mechanical device, with maintenance of good maintenance can extend the life of the machine, here is the next Changzhou hydraulic how proper care and maintenance. 1. Working oil recommended 32, 46 anti-wear hydraulic oil, use oil in the range of 15 to 60 degrees Celsius. 2. Oil strictly filtered before allowed to join the tank. 3. Working fluid change every once a year, of which the first time should not exceed three months to replace; 4. Slider should always note lubricants, column looks appearances should be kept clean, each work should be preceded by injection oil. 5. 500T concentrated load at nominal maximum allowable eccentricity 40mm. Eccentric easy to make too much strain or column appears other undesirable phenomena. 6. Pressure gauge calibration check once every six months; 7. Machine than the long-term disabled, plus various parts of the surface should be cleaned and coated with anti-rust oil. This device is particularly suitable for the central part of the load bending, forming, flanging and other technology, coupled with blanking buffer device, could also be used for punching, blanking processing, ship industry, pressure vessel industry, chemical industry product of choice.
