Abstract

The adjustable pumping device is designed to supply alternating volume discharge to the actuating mechanisms of displacement hydraulic drives. It attains smooth and precision adjustment of the discharge from zero to maximum and vice versa by making use of standard non-regulated hydraulic machines which are cheap, compact and reliable. The device comprises of an adjustable electric motor (1), mechanically connected to a basis non-adjustable and non-reversible displacement pump (2), reservoir with operation liquid and pipe connections. To the composition of the pumping device also an auxiliary hydraulic motor-pump is included, mechanically connected to an asynchronous electric motor of independent or parallel and mixed, coaxial excitation. The outlet of the basic pump (2) is hydraulically connected by means of pipe connection (5) to the inlet of the motor-pump (7), and a safety valve (13) and reversing valves (3, 6) are hydraulically connected in parallel to the pipe connection (5) for one-way isolation, from the pressure (4) and an auxiliary intake (12) pipeline, respectively. The hydraulic output of the motor-pump (7) is connected to the overflow pipeline (9) in the system. 2 claims, 2 figures
