A hydraulic self-driven drag-reducing mucus dilution release device

Abstract

The invention discloses a hydraulic self-driven drag-reducing mucus dilution and release device, which is composed of a mucus nozzle, a dilution and mixing cavity, a stirring rod and a release nozzle. The electromagnetic flowmeter is installed on the water inlet pipe, the dilution and mixing chamber is located at the back of the water inlet pipe, the dilution and mixing chamber is connected with the release nozzle as an integral structure, the release nozzle is a tapered section, and the stirring rod is located in the dilution and mixing chamber through the bearing. Connected to the dilution mixing cavity, the mucus nozzle is fixed in the front through hole of the dilution mixing cavity and is in interference fit with the through hole. The dilution and blending cavity is self-driven by inflowing water to achieve uniform blending. The design of the stirring rod prevents the breakage of the drag-reducing mucus polymer chain during stirring and blending, and the drag-reducing effect is lasting and effective. The drag-reducing mucus dilution and release device can realize the dilution, blending and spraying of drag-reducing mucus sharing a dilution and mixing cavity, and has a simple structure and great engineering application value.

Description

Technical field [0001] The present invention relates to underwater steam displacement growth techniques, and more particularly to a hydraulic self-driven reducing mucus dilution release device. Background technique [0002] The speed of ship and underwater aircraft is an important indicator of its performance. At the same input power, the speed of speed is closely related to the size of the resistance. The resistance of the ship and underwater steam is composed of friction resistance, differential pressure resistance, and Xing wave resistance. The frictional resistance is the highest. Reduce frictional resistance is the main method of growth rate consumption, currently the mainstream reduction method has superhydrophobic reduction, trench reduction, microbubble reduction, and flexible wall deduction. The highlighter or surfactant has a good reduction property as a reducing mucus has reached a consensus, and some researchers have proposed some solid particulate suspension mucus to...

Problems solved by technology

In the invention patent CN201910168276.3 "A Mucus Drag Reduction Device for Underwater Vehicles", the drag reduction device includes a liquid storage tank and a shunt pipe. By designing a drag reduction mucus injection device, the consumption of its drag reduction mucus is reduced. Drag-reducing mucus can only play a drag-reducing role at low concentrations. Due to the limited power consumption and space of the aircraft, it is not suitable to carry too much drag-reducing mucus

In the invention patent CN201811053561.2 "A Rapid and Uniform Dilution Device for Thick Polymer Mucus", the dilution device includes a storage room, a mixing section, and a pipe bend section, which can enable the aircraft to carry a small amount of high-concentration drag-reducing mucus. Low-concentration drag-reducing mucus is obtained by diluting in the mixing section and blending in the elbow section. However, the blending in the elbow section brings about a large loss along the way, and on the other hand, the large bending range makes it difficult to release the drag-reducing mucus. Even clogging due to prolonged release of mucus
