  DSF-A (B, C, D, E)-type electric hydraulic feeder three points with a putt for electro-hydraulic power source. Because of its automatic overload protection performance when running blocked, the oil pressure is increased to the tune of the limits set overflow relief quickly and accurately implement overload protection. The motor is running will not burn in the ratings. When it is set to run putter stroke end, the electro-hydraulic pusher in the oil manifold designed self-locking mechanism, the motor is stopped, the piston rod is self-locking in this position, in packing state.   which DSF-A (B)-type electric hydraulic three points can be used for materials commutation feeder / shunt flow. And allowing the material flow has outdated commutation; DSF-C (D, E) can be three types of hydraulic power feeder can be used to change the shunt flow of material, and the kinetic energy with the shutter; while simultaneously controlling the material flow or cutting action.   working principle is driven by three electro-hydraulic pusher shaft can be sub-feeder mechanism to control flap flip, reach the material for the role.   This product can be connected directly to the upper flange at the head of the tape machine interface under the funnel material or other equipment, which are generally used in the bulk specific gravity less than or equal 2.8t / m, and the larger abrasive, harsh working conditions Under conditions. Taking into account the structure of large size, heavy weight (liner wear thick), the upper flange can not bear its own weight, are subject to the support of the actual situation.
