A hydraulic loading system for steering gear

Abstract

The embodiment of the invention provides a hydraulic loading system for a steering engine. The hydraulic loading system for the steering engine comprises a valve integrated block, a first hydraulic cylinder, a second hydraulic cylinder, a first energy accumulator, a second energy accumulator, a rack, a servo valve module and a stop valve module, wherein the valve integrated block, the first energyaccumulator and the second energy accumulator are fixed to the rack; the first hydraulic cylinder and the second hydraulic cylinder are respectively connected with the valve integrated block; an oilsupply port of the valve integrated valve is connected with an oil supply pipeline; an oil return port of the valve integrated valve is connected with an oil return pipeline; the first energy accumulator is connected between the oil supply port of the valve integrated valve and the oil supply pipeline; the second energy accumulator is connected between the oil return port of the valve integrated valve and the oil return pipeline; and the servo valve module and the stop valve module are arranged on the valve integrated block. According to the hydraulic loading system for the steering engine provided by the embodiment of the invention, through the combination of on / off of the stop valve on the valve block, and by combining with the control of the servo valve, the configuration of multiple oil circuits and the hydraulic loading are realized.

Description

technical field [0001] The invention relates to the technical field of hydraulic loading, in particular to a hydraulic loading system for steering gear. Background technique [0002] The hydraulic system has the advantages of large bearing capacity and high power-to-weight ratio, and plays an important role in industrial production, aerospace, ships and other fields. The ship field is an important branch of the industrial field, and the performance test of its steering gear is very important in the design of the steering gear. [0003] Due to the complex and changeable underwater environment, the load simulation of ship steering gear generally has the characteristics of large output force, large inertia and large load flow, and the hydraulic drive scheme is often used as the load simulation loading method of steering gear. However, most of the existing hydraulic loading systems have shortcomings such as poor versatility, bulky overall structure, and inconvenient installatio...
