Description

Electronic hydrostatic executive device working fluid composite

Technical field

The invention belongs to electronic hydrostatic executive device lubricating oil field, particularly electronic hydrostatic executive device working fluid composite.

Background technology

Electronic hydrostatic executive device is a kind of electrohydraulic servo system based on closed circuit, usually has according to the different working modes of drive-motor and hydro-pump: fixed displacement becomes rotating speed, change discharge capacity determines rotating speed and becomes discharge capacity becomes rotating speed three kinds of forms. Wherein, fixed displacement become rotating speed be by control motor turn to the execution direction and rotating speed that control executive device with rotating speed. Other two schemes relatively, simplifies in efficiency and structure and has more advantage, be the main technology used at present.

Electronic hydrostatic executive device is power-by-wire and system actuator. It can be converted into local hydraulic pressure electric energy, can have conventional hydraulic and the advantage of direct driven by power executive device concurrently; Possess high torque (HT) and high-power density simultaneously, and for modularization. Their composition is usually by high speed direct-current machine, high speed ram pump; Energy storage is used for preventing working fluid from producing air pocket, it is possible to is leaked by the working fluid in working process and supplements; Safety valve is used for preventing internal system from producing too high pressure; By-pass valve is opened when system malfunctions, makes working fluid directly return pump by by-pass valve, plays the effect blocking fault. Owing in system, hydro-cylinder is directly connected with pump, therefore arranging a symmetrical hydraulic cylinder, its input and output amount is equal. Employing speed, pressure, displacement sensor are connected with controller, it is possible to supervised by system and device, and control in real time according to sensor parameters. It require working fluid have high anti-shear ability, good sticky-temperature characteristics, low-temperature startup, high-temperature oxidation stability, high-mechanic, high workload pressure, low frictional properties, rust-preventing characteristic, cleaning, high speed and cooling etc.
