A kind of control method of explosive spraying equipment for aero-engine

Abstract

The invention discloses a control method for explosion spraying equipment for an aero-engine. A control system is mainly composed of a PLC, a touch screen, a servo system and other key parts. According to the related requirements of the explosion spraying technology, the explosion spraying equipment with the improved control system comprises functions of several parts including spraying process control, air path flow detection, adjustment and control, spraying parameter monitoring and the like. Corresponding control and monitoring can be conducted on an operation panel and the touch screen. A human-machine interface based on the touch screen is convenient to configure, and easy and convenient to operate. The system achieves automatic cyclic control of spraying and also combines manual control. An air path detection and adjustment part is mainly used for collecting signals of flow pressure and the like and sending the signals to the PLC, displaying is conducted on the touch screen so that operation and personnel monitoring can be convenient, and the flow pressure is adjusted so that the technology parameter requirement can be met. The control method has the beneficial effects that the production efficiency of the equipment is improved, the labor intensity of operators is lowered, the application prospects of the control method are very wide, and popularization value is achieved.

Description

technical field [0001] The invention relates to the field of explosive spraying control for aero-engines, in particular to a method for controlling explosive spraying equipment for aero-engines. Background technique [0002] Explosive spraying equipment frequently breaks down. The original control system is electronic circuit board control. The cause of the failure is the aging of key components and poor contact of relay contacts. Since the electronic circuit board components are not of international standards, they need to order from abroad after a failure occurs. The procurement cycle is long, which seriously affects the production progress; It is easy to cause a short circuit in the process, and there will be endless troubles. The operation buttons on the operation panel are in poor contact, some are even damaged, and it is difficult to replace them. More importantly, the equipment cannot meet the test requirements of new products and new processes. Contents of the in...
