Abstract

The invention discloses a rotating blade type steering engine fault detecting device and method, and belongs to the field of marine mechanical equipment. The detecting device comprises a detecting module and a logic module, wherein the detecting module is used for detecting multiple parameters; the multiple parameters comprise real-time pressure of an oil outlet of a hydraulic pump and real-time pressure of a helm shifting mechanism; the logic module is used for detecting faults of a rotating blade type steering engine according to the multiple parameters; when the real-time pressure of the oil outlet of the hydraulic pump is lower than an oil outlet pressure set value, the hydraulic pump is broken down; and when the hydraulic pump is not broken down, and the real-time pressure of the helmshifting mechanism is lower than a helm shifting mechanism pressure set value, a hydraulic pipeline or a valve piece of the helm shifting mechanism is broken down. The detecting device is simple in judgment mode, can be convenient for workers to quickly determine broken parts in the rotating blade type steering engine, and is convenient to maintain.

Description

technical field [0001] The invention relates to the field of marine mechanical equipment, in particular to a fault detection device and method for a rotary vane steering gear. Background technique [0002] Steering gear is an indispensable equipment for ships to turn. Common steering gears include rotary vane steering gear and reciprocating plunger steering gear. Because the rotary vane steering gear takes up less space, it has more advantages than the reciprocating plunger steering gear. [0003] The rotary vane steering gear mainly includes a steering mechanism, a steering mechanism and a hydraulic system. The hydraulic system includes a fuel tank, a hydraulic pump, a pipeline, and a motor that drives the hydraulic pump. The hydraulic system can provide hydraulic oil to the rudder steering mechanism, so that the rudder steering mechanism drives the rudder steering mechanism to rotate to perform rudder steering. [0004] The structure of the rotary vane steering gear is r...
