Hydraulic Drive for Opening and Closing the Coke Discharge Doors of Quenching Cars

Abstract

Selection of the hydraulic drive and automation system for opening and closing the coke discharge doors of the quenching car is considered. The goal is to determine the best equipment for the hydraulic drive and the best pumping station mounted in the locomotive so as to ensure effective discharge of the quenched coke on the sorting ramp, at the required rate and with uniform coke distribution over the length of the ramp. Components are proposed for the hydraulic drive that opens and closes the coke discharge doors of the quenching car. Hydraulic cylinders with built-in sensors for monitoring the position and speed of the moving components (the cylinder rods and connectors) are employed. In the hydraulic drive, the operation of the hydraulic cylinders is regulated by means of distributors with proportional control. The use of hydraulic drive systems and hydraulic automation in coke production ensures efficient operation of the equipment—in particular, uniform distribution of the quenched coke over the sorting ramp. Design features proposed for the hydraulic pumping station in the locomotive ensure effective opening and closing of the coke discharge doors in the quenching car on the basis of hydraulic accumulators and auxiliary equipment.
