Control device and method for low vortex shaft ultrasonic cleaning equipment of aero-engine

Abstract

The invention belongs to a control device and method for ultrasonic cleaning equipment of a low turboshaft of an aviation motor and belongs to the technical field of aviation motors. The device comprises a liquid level sensor, a medium relay, a first temperature control instrument, a second temperature control instrument, a first temperature sensor, a second temperature sensor, a first timer, a second timer, a first contactor, a second contactor, a third contactor, a fourth contactor, a fifth contactor, an air inlet solenoid valve, an air pressure cylinder direction solenoid valve, a cleaning slot switch, a liquid storing slot switch, a vibration plate switch, a vibration bar switch, a circulation pump switch, an air source switch and a switch for controlling the cover of a cleaning slot. The control device and method for the ultrasonic cleaning equipment of the low turboshaft of the aviation motor have the functions of automatic temperature controlling on cleaning liquid, liquid level alarming and protecting, ultrasonic work timing and electric leakage protecting, and ensures the smooth assembly of the motor; the production efficiency of parts of the motor is improved after the parts are cleaned, the service life and the reliability are improved, and the development demands of the national aviation industry are met.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, and in particular relates to a control device and method for an aero-engine low-turbine ultrasonic cleaning device. Background technique [0002] The control system of the low vortex ultrasonic cleaning equipment is to control the cleaning equipment to complete the cleaning of the long shaft parts and blisk parts of the aero-engine, so as to meet the surface cleanliness requirements before the parts are assembled. At present, the ultrasonic cleaning equipment in the domestic market has low power , the operating system cannot meet the cleaning requirements of aero-engine long shaft parts and blisk parts, which greatly affects the engine assembly and test run process, and there is no ultrasonic cleaning control device directly used only for aero-engine low-turbine shafts. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a control ...
