Power suction device

Abstract

The invention discloses a power suction device. The power suction device comprises a suction assembly, the suction assembly is installed at the bottom of an oil tank, an inlet of the suction assembly is communicated with the inside of a gearbox through an oil suction pipe, an outlet of the suction assembly is located in the oil tank, and the suction assembly is used for sucking redundant oil in the gearbox into the oil tank; and the suction assembly is connected with a power pipe, and the power pipe provides a power source for oil suction of the suction assembly. The power source is provided for the suction assembly through the power pipe, the power source forms a high-pressure and high-flow-speed power source after passing through a damping spray head, and when the high-pressure and high-flow-speed power source passes through an injection pipe and then is diffused upwards, certain negative pressure is generated at an oil suction opening of a suction connecting pipe, so that oil and foam in the gearbox are automatically sucked into an oil suction pipeline, redundant oil is completely sucked into the oil tank, the liquid level in the gearbox is kept below a transmission gear all the time, and therefore the problem of power loss caused by oil stirring of the transmission gear is effectively solved.

Description

technical field [0001] The invention relates to the technical field of thruster oil suction equipment, in particular to a power suction device. Background technique [0002] With the development of the ocean from the offshore to the deep sea, the tonnage of the ship is also increasing, and the overall performance of the ship is also continuously improving. The performance of the propeller is also required to be changed, and the propeller is required to be more efficient. , more energy-saving. [0003] However, for propellers of small and low-power end products, domestic manufacturers basically adopt the method of immersion lubrication, and the interior of the propeller gearbox cavity is filled with lubricating oil, but due to the influence of oil churning on the propeller transmission gears and bearings, it has a relatively large impact on the transmission power. Therefore, a suction device is needed to suck away the excess oil in the propeller, eliminate the oil churning e...

[0003] However, for propellers of small and low-power end products, domestic manufacturers basically adopt the method of immersion lubrication. The interior of the propeller gearbox cavity is filled with lubricating oil, but due to the influence of oil churning on the propeller transmission gears and bearings, the transmission power is relatively large. Therefore, a suction device is needed to suck away the excess oil in the propeller, eliminate the oil churning effect of transmission gears and bearings, and reduce power loss
