Abstract

The invention discloses a preventive maintenance judgment method, device and equipment for a main condenser and a storage medium. A pipeline is connected to the outer end of the main condenser of an autoclave, a temperature sensor and a water flow sensor are additionally installed, and operation data are collected in real time; acquired recording time, water flow of a main condensation pipeline, actual measurement temperature of the autoclave and set temperature of the autoclave are selected to be extracted and analyzed, a cooling interval and a cooling slope are screened, stable water flow is solved, historical data are combined, and preventive maintenance judgment is performed. The technical problems that in the prior art, a main condenser is of a totally-enclosed structure in a branch pipe array form with cooling fins, is located at the tail of an autoclave and is very difficult to disassemble and overhaul, and once dominant faults occur, the time is late, the forming quality and the machining efficiency of composite parts of the whole autoclave are affected, and losses are huge are solved.

Description

technical field

[0001] The present application relates to the technical field of aircraft manufacturing, and in particular to a preventive maintenance judgment method, device, equipment and storage medium of a main condenser. Background technique

[0002] Advanced composite materials mainly refer to resin-based composite materials reinforced with high-performance fibers (such as boron fibers, carbon fibers, and aramid fibers), which have the advantages of high temperature resistance, fatigue resistance, damping and shock absorption, good damage safety, and designable performance. , Gradually replace metal parts, and obtain important applications on the surface of modern aircraft. The autoclave is the key equipment in the curing and molding process of composite materials. It uses the high temperature in the tank and the pressure generated by the compressed gas to heat and pressurize the composite material blank to complete the curing and molding of the parts, and the parts ar...

Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0042] The main solution of the embodiment of this application is:

[0043] obtain the current data in the database of the main condenser;

[0044] Draw a line graph based on the current data;

[0045] Obtain target data based on the line chart;

[0046] Based on the target data, a preventive maintenance judgment for the main condenser is made.

[0047] The main condenser installed in the autoclave has an important influence on the temperature regulation ability during the curing process of the autoclave parts and the cooling ability at the end, but the main condenser is a fully enclosed structure in the form of a branch pipe array with cooling fins. It is extremely difficult to disassemble and repair the tail of the autoclave. Once an obvious failure occurs, it will be too late, affecting the ...
