PNEUMATIC HYDRAULIC PUMP-BOOSTER

摘要

mechanical engineering. SUBSTANCE: pump-booster is used as supply source during hydraulic tests of vessels and apparatus. Hydraulically-controlled pneumatic throttle is introduced into line of pressure supply to pneumatic cylinder. Control line serves as pressure feedback in delivery line. Plungers of hydraulic cylinders are secured on pneumatic cylinder body. Hydraulic cylinders are made in recesses of pneumatic cylinder rods. Pushers of control air distributors interact with pneumatic cylinder rods. Constant efficiency of pump-booster is provided at delivery pressure variation. EFFECT: reduced dynamic loads. 1 dwg
