Abstract

The invention relates to a fuel oil balancer which comprises a fuel oil balancer shell, a balance weight, a spring and a sealing ring. The fuel oil balancer shell is a cylinder, wherein through holes are formed in the axis of the cylinder. The first through hole is formed in the fuel oil balancer shell. The axis of the first through hole is perpendicular to the axis of the fuel oil balancer shell. The second through hole is formed in the fuel oil balancer shell. The axis of the second through hole is perpendicular to the axis of the fuel oil balancer shell. The fuel oil balancer shell is arranged in a main oil pipe, and a gap is formed between the main oil pipe and the fuel oil balancer shell. The balance weight and the spring are arranged in the through holes of the fuel oil balancer shell. The balance weight is in sliding contact with the inner hole of the fuel oil balancer shell. The outer surface of the cylinder of the fuel oil balancer shell and the main oil pipe are sealed through a sealing ring. The static pressure effect generated due to dead weight of fuel oil inside the main fuel oil pipe can be eliminated, it is ensured that the oil supply amounts of nozzles are consistent, and the problems that due to the fact that the oil supply amounts of the nozzles are different, the combustor outlet temperature distribution is not uniform, and then the reliability and service life of an engine are affected are solved.

Description

technical field [0001] The invention belongs to the field of aero-engine design, in particular to a fuel balancer. Background technique [0002] Fuel nozzles are key components of aero-engines and play an important role in engine performance. The performance of the nozzle will affect the performance of ignition, combustion efficiency, combustion stability, temperature distribution, exhaust pollutants and other aspects. Such as figure 1 Shown is a commonly used fuel manifold with nozzles without a fuel balancer at present, including the main oil inlet pipe 101, the fuel oil main pipe 102 and the nozzle 103. , the nozzle 103 is composed of the nozzle housing 104, the main oil pipe 106, the auxiliary oil pipe 107 and the nozzle 105. Each nozzle 103 is evenly distributed on the fuel main pipe 102 in the circumferential direction. Since the fuel main pipe 102 is installed vertically, the nozzles 103 at the top and the bottom, due to the The pressure difference produced by its ...
