Abstract

The invention belongs to the field of aero-engine ignition plug design, and relates to aero-engine torch ignition plug portable flow test equipment which comprises a permanent magnet motor (1), a plunger pump (2), apressure gauge (4) and a measuring cup, wherein the plunger pump (2) is connected to an output shaft of the permanent magnet motor (1), the plunger pump (2) comprises an oil pump oil inlet connector and an oil pump oil outlet connector, the oil pump oil inlet connector is connected with an oil tank (10), and the oil pump oil outlet connector is connected with a torch ignition plug (9) through a hose (3); the pressure gauge (4) is arranged on the hose (3); and the measuring cup is placed below the outlet of the torch ignition plug. The permanent magnet motor is connected with the miniature plunger pump, aviation kerosene is injected into the torch ignition plug from the oil tank, then the flow of the ignition plug is measured through the measuring cup, the advantages of being small in size, convenient to carry and use and the like are achieved, and flow detection of the torch ignition plug can be rapidly conducted.

Description

technical field [0001] The application belongs to the design field of an aero-engine ignition electric nozzle, and in particular relates to a portable flow test device for an aero-engine torch electric nozzle. Background technique [0002] At present, during the use of the ignition nozzle, the flow rate is prone to increase. To solve this problem, the existing solution includes long-term and multiple verifications of the ignition nozzle flow rate with the flight of the aircraft. In order to ensure that the product is used in the army To ensure the reliability of the military training missions, it is necessary to conduct a general survey of field products. Under the oil pressure of 0.392Mpa aviation kerosene, check the flow rate of the electric nozzle, which should not exceed 130ml / min. [0003] The torch ignition nozzle adopts a pressure nozzle as a single-hole nozzle, and the atomization is a hollow cone. The most important design index affecting the atomization of the torc...
