Debugging method of air balance system of airplane paint spraying hangar

Abstract

The invention provides a debugging method for an air balance system of an airplane paint spraying hangar. The debugging method comprises the following steps: checking a mounting condition of the air balance system and checking the function of the air balance system; mounting air volume test holes in an air pipe of the air balance system, and determining the distance between the test holes according to the size of the air pipe; measuring the unit total air volume of the air balance system and determining the unit frequency and adjusting the unit total air volume; adjusting electric valves of all the main pipes and finally achieving air volume balance of the main pipes; measuring data of tail end air ports, adjusting tail end hand valves of branch pipes and adjustable shutters (OBD) of the tail end air ports according to the data, and finally completing air volume balance of the branch pipes; measuring the air volume and the air pressure of the main pipes again, and adjusting air volume balance again; and measuring air speeds of all the exhaust grilles, and adjusting the air volumes of the exhaust grilles. The debugging method has the characteristics of simple steps, high practicability, high adjustment precision and clear and definite debugging steps.

Description

technical field [0001] The invention relates to a debugging method for a wind balance system of an aircraft painting hangar. Background technique [0002] The painting hangar is the most critical link before the delivery of the aircraft. It is used to spray the appearance marks of various airlines. Since the automatic painting technology in the world is not yet mature, manual painting is still required. If the painting fails, the cost is high, so the uniformity of the air supply and exhaust Strict requirements have been made for permanent regulation, and CFD airflow simulation and on-site smoke test to observe the gas flow state are required for evaluation, so as to achieve the purpose of one-time spray painting. However, in the prior art, the wind balance regulation system of the spray booth is all studied. , rarely involves the debugging method of the wind balance system. The success of wind balance system debugging directly affects the success rate of painting, and the e...

[0002] The painting hangar is the most critical link before the delivery of the aircraft. It is used to spray the appearance marks of various airlines. Since the automatic painting technology in the world is not yet mature, manual painting is still required. If the painting fails, the cost is high, so the uniformity of the air supply and exhaust Strict requirements have been made for permanent regulation, and CFD airflow simulation and on-site smoke test to observe the gas flow state are required for evaluation, so as to achieve the purpose of one-time spray painting. However, in the prior art, the wind balance regulation system of the spray booth is all studied. , seldom involves the debugging method of the wind balance system

The success of the wind balance system debugging directly affects the success rate of painting, and the existing debugging methods are often more complicated, and the adjustment accuracy is not enough, the debugging steps are not clear, and it is difficult to meet the requirements

[0003] Therefore, there is a need for a debugging method for the wind balance system of aircraft painting hangars, which can solve the problems in the prior art that the debugging method is complicated, the adjustment accuracy is not enough, the debugging steps are not clear, and it is difficult to meet the requirements
