Dynamic double-frequency ultrasonic cleaning and drying method and device

Abstract

The invention discloses a dynamic double-frequency ultrasonic cleaning and drying method and device. The dynamic double-frequency ultrasonic cleaning and drying device is composed of following equipment, namely, a soaking tank, an ultrasonic double-frequency cleaning tank, an ultrasonic rinsing tank, circulating pumps, dynamic circulating filters, nitrogen pressure blowing water, an ultrasonic system, a circulating filtering system and a heating system; an inlet pipeline connected to a nozzle in a butt joint mode is fixedly arranged on one side of the inner wall of each of the ultrasonic double-frequency cleaning tank and the ultrasonic rinsing tank; and one dynamic circulating filter is fixedly arranged on one side of the exterior of each of he ultrasonic double-frequency cleaning tank and the ultrasonic rinsing tank. According to the dynamic double-frequency ultrasonic cleaning and drying method and device, the nozzle is soaked through the soaking tank, so that impurities attached tothe surface of the nozzle and carbon deposit accumulated in the nozzle are decomposed, dust on the surface of the nozzle and carbon deposit inside the nozzle are removed through the cooperation of the ultrasonic cleaning tank and the dynamic circulating filters, it is guaranteed that the interior and the surface of the nozzle can both be cleaned, the carbon deposit is prevented from remaining inside the nozzle, and in addition, the cleaning efficiency is high.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a dynamic dual-frequency ultrasonic cleaning and drying method and device. Background technique [0002] The fuel nozzle belongs to the technical field of the engine, including the cavity, the oil valve and the nozzle cap. When the fuel pressure in the oil chamber is higher than the set value, the fuel valve is opened, and the fuel is ejected through the nozzle cap. The fuel valve is composed of the valve body, valve seat and nozzle cap. Composed of springs, the rear end of the valve seat is connected with the cavity to form an oil cavity, and the cavity is provided with an inlet passage into the oil cavity, the spring is located in the oil cavity, and acts between the valve body and the valve seat to close the oil valve, the valve seat The front end of the nozzle cap is connected to form a residual volume, and the nozzle cap is provided with a spray hole connected to the resi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a dynamic dual-frequency ultrasonic cleaning and drying method and device, capable of cleaning the surface and interior of the nozzle at the same time, ensuring that both the interior and the surface can be cleaned, and preventing carbon deposits from remaining in the nozzle The advantage of high cleaning efficiency is that the existing nozzle cleaning method only has obvious effects on the carbon deposition on the surface, but the effect on the inside is not obvious, the cleaning efficiency is low, and the impurities inside Problems that are not easy to clear
