ED-121 ELECTRO HYDRAULIC AND THRUSTER

Introduction to the characteristics of electrohydraulic thrusters

The working principle of the electro-hydraulic pusher: when the power is turned on, the electro-hydraulic pusher moves, and its push rod rises rapidly, and the brake shoe is opened (loosen the brake) through leverage. When the power is cut off, the push rod of the electro-hydraulic pusher Under the action of the spring force, it descends rapidly, and closes the brake shoe through leverage (holding the news).

Electrohydraulic pushers are often used in conjunction with brake racks and are widely used for braking of various transmission devices. It can work continuously S1 and continue to work S3, the basic ambient temperature reaches +50°C

The rated current in the table of the electro-hydraulic pusher refers to the terminal current during rated operation, but if the power supply is not rated, it will inevitably cause a corresponding change in the rated current. Ambient temperature: -20C~+50C, hydraulic oil: When DB-25 (SY1351-77) is lower than -20C, use YH-10 hydraulic oil, no heater is required, and DB-25 hydraulic unit must be equipped with a heater. Travel times are measured at an ambient temperature of 20°C.
