This invention discloses an oil draining device and method for a lubricating oil radiator. The oil draining device includes a fixed support, an oil storage tank, a drain pipe, and a vacuum pump. The fixed support secures the lubricating oil radiator so that the drain port faces vertically downwards. The oil storage tank collects the drained oil and has a drain pipe at the bottom. The Venturi-type drain pipe connects the radiator to the oil inlet of the oil storage tank, accelerating oil flow. The vacuum pump is connected to the oil storage tank through a negative pressure pipeline, creating a stable negative pressure environment to provide power for oil suction. This invention, by using a fixed support to ensure the drain port faces vertically downwards and utilizing gravity to assist in oil draining, and by using the Venturi-type drain pipe to accelerate oil flow, combined with the negative pressure environment created by the vacuum pump in the oil storage tank, can significantly improve the efficiency of conventional oil draining. Furthermore, even if the vacuum pump fails, the Venturi-type drain pipe can still ensure smooth oil draining, thus meeting the oil draining needs of aviation maintenance.

The utility model has realized the anti -freezing liquid filling work of heat dissipation water tank outside square cabin power station to can set up heat dissipation water tank to the position of being very close to cabin top, fully releases the space in cabin, realizes the full use of narrow space in cabin, and further improved the rationality of cabin layout.

This application relates to the field of nozzle technology and discloses a high-uniformity electrostatic misting nozzle structure, including a nozzle body with a liquid inlet at one end and a mist outlet at the other end. The nozzle body has an internal mounting cavity for mounting an atomizing component. The atomizing component includes a pressure atomizing nozzle and a rotating atomizing disc. The pressure atomizing nozzle is installed at the liquid inlet of the nozzle body, and the rotating atomizing disc is rotatably connected to the inner wall of the nozzle body via a mounting ring, and is opposite to the liquid outlet direction of the pressure atomizing nozzle. The rotating atomizing disc is driven to rotate by a drive mechanism outside the nozzle body. In this invention, the electrostatic generating component charges the droplets, enhancing the electrostatic adsorption force between the droplets and the surface of plants or sprayed objects. Compared to traditional nozzles, the droplets adhere more firmly, reducing waste caused by drifting and slippage, improving the utilization rate of pesticides, coatings, and other materials, reducing costs, and reducing environmental pollution.
