Integrated small embedded hydraulic oil source

Abstract

The invention discloses an integrated small embedded hydraulic oil source. The integrated small embedded hydraulic oil source comprises a channel body (1), a motor (2), a high-pressure pipe joint (3), a low-pressure pipe joint (4), an oil filter cover, an oil box cover, an oil filter and a constant-pressure variable pump core, and further comprises a low-pressure oil injecting valve, a high-pressure oil injecting valve, a supercharging oil tank and a retainer ring. The integrated small embedded hydraulic oil source adopts the channel body (1) as a shell of the constant-pressure variable pump core, an installation basal body of all parts and an oil storage basal body; the effective effect area ratio of the supercharging oil tank in the high-pressure cavity and the low-pressure cavity is smaller; the pressure ratio of the high-pressure cavity and the low-pressure cavity is guaranteed; a certain pressure of the low-pressure cavity is maintained; the oil sucking effect of the constant-pressure variable pump core and the pressure building time of the oil source are guaranteed; the integrated small embedded hydraulic oil source has such functions as self-supercharging, oil storage and pressure pulsation absorption; and the high-pressure oil injecting valve and the low-pressure oil injecting valve synchronously serve as vacuumizing and oil injecting joints, so that the oil injecting effect of the channel body is guaranteed.

Description

technical field [0001] The invention relates to a hydraulic oil source, in particular to an integrated miniaturized embedded hydraulic oil source. Background technique [0002] Electrohydraulic steering gear has technical characteristics such as large output power, large power-to-weight ratio, high control precision and fast dynamic response, and has been widely used in medium and long-range surface-to-air missiles. At present, the hydraulic oil source of domestic electro-hydraulic steering gear is generally composed of a motor, a constant pressure variable pump, an accumulator, a filter, a fuel tank, and an integrated block; the motor drives a constant pressure variable pump to suck low pressure oil from the fuel tank, and the output high pressure oil passes through The filtered output of the filter is sent to the external system; the role of the accumulator is to absorb the pressure pulsation of the oil source and provide auxiliary oil supply when the system requires a lar...
