Abstract

The invention discloses a high-precision hydraulic power source which uses a speed regulating motor to drive an oil pump directly, and belongs to the technical field of hydraulic power installation. The high-precision hydraulic power source comprises an actuating mechanism, a reversing valve, an oil tank, servo drive units, a data acquisition and control system, and a feedback unit, wherein the reversing valve is connected with the actuating mechanism, the servo drive units are connected with the reversing valve, the data acquisition and control system is connected with the servo drive units, the feedback unit is connected with the data acquisition and control system, and the actuating mechanism is connected with the feedback unit; and the servo drive units have two groups which are parallelly connected with the reversing valve, one group of the servo drive units is in charge of controlling the oil feed for the actuating mechanism, while the other group is in charge of controlling the oil discharge for the actuating mechanism. The high-precision hydraulic power source has the advantages of energy conservation and high control precision.

Description

technical field [0001] The invention discloses a high-precision hydraulic power source directly driving an oil pump by a speed-regulating motor, which belongs to a hydraulic power control device and can be widely used in various technical fields requiring high-precision control of force, displacement and speed. Background technique [0002] As we all know, hydraulic power sources have been widely used in various fields, mainly using ordinary motors to drive ordinary quantitative pumps to deliver oil to the working cylinders, and adjusting the output pressure of the power unit through regulating valves (flow valves) or overflow valves (pressure valves). and action speed, the advantage is easy maintenance, so until now there are still a large number of hydraulic power sources using this method, the disadvantage is that the oil pump is always outputting oil at a large flow rate, which causes the temperature of the hydraulic oil to rise too high, which leads to the need for cooli...
