Embodiment Construction

[0035] The schematic diagram of the new pump-controlled hydraulic transmission system directly servo-driven by the switched reluctance motor of the present invention is shown in Figure 2. The system includes a hydraulic cylinder with a piston in the hydraulic cylinder. It is characterized in that the two ends of the hydraulic cylinder are connected by pipelines. Axial embolism pump, the axial embolism pump is driven by a switched reluctance motor, and the switched reluctance motor realizes the reciprocating movement of the hydraulic cylinder in forward and reverse directions, and the oil tank is connected to the pipeline through a hydraulic control check valve and a check valve.

[0036] Its working principle is that the switched reluctance motor drives the axial piston pump to work and pressurizes the low-pressure oil. The low-pressure oil flows into the hydraulic cylinder after being pressurized, and pushes the piston to do work. Due to the different areas on both sides of t...

Abstract

The invention discloses a switch reluctance motor direct servo driving new pump control hydraulic transmission system. It contains hydraulic cylinder with piston in it. The characteristics of system are that, two ends of hydraulic cylinder connect to quantitative pump with pipe. The pump drives by switch reluctance motor, which realizes round trip motion of hydraulic cylinder by its normal-reverse transfer. Pipe connects to oil tank by fluid check valve and check valve. The invention using switch reluctance servo motor, prevent reduce throttle, overflow and unloading loss, improve efficiency motor and power factor. This is inextricable by other hydraulic speed control mode.

Description

technical field [0001] The invention belongs to the field of forming equipment manufacturing, and in particular relates to a novel pump-controlled hydraulic transmission system directly servo-driven by a switched reluctance motor. Background technique [0002] After entering the 1990s, with the increasingly stringent requirements for environmental protection, such as energy consumption, noise, leakage and other control aspects of the world, energy saving has become one of the main research directions and focuses of electro-hydraulic systems. Therefore, it is particularly important to conduct research on new hydraulic transmission and control methods. [0003] In the hydraulic transmission control system in practical application, most of them need to control the speed of the actuator. It can be said that the speed regulating circuit is the core of the hydraulic system. There are many ways to adjust the speed of the hydraulic system, but in general it ...
