Open type rotating oil station with annular breathing pipes

Abstract

The invention relates to the technical field of wind power generation equipment, in particular to an open type rotating oil station with annular breathing pipes. The open type rotating oil station comprises a rotating oil tank, an oil pump motor set, an oil pump oil suction pipe and an oil pump oil outlet pipe, the multiple annular breathing pipes are uniformly wound on the periphery of the rotating oil tank, inlets of the annular breathing pipes communicate with the rotating oil tank, and outlets of the annular breathing pipes communicate with the external atmosphere; and the winding direction of the annular breathing pipes from the inlets to the outlets is the same as the rotating direction of the rotating oil tank, the annular breathing pipes are used for enabling oil in the annular breathing pipes to flow back to the rotating oil tank, and in the rotating process of the rotating oil tank, one annular breathing pipe enables the atmosphere in the rotating oil tank to always communicate with the external atmosphere and is used for maintaining pressure in the rotating oil tank and atmospheric pressure balance. By means of the rotating oil station, the problems that the structure is complex, leakage is prone to occurring, and maintenance is inconvenient can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to an open rotary oil station with an annular breathing pipe. Background technique [0002] Electricity is one of the important energy sources for industrial production and daily life applications. With the decreasing of non-renewable resources, the superiority of wind power generation is becoming more and more obvious. At present, the oil station of the hydraulic pitch control system of wind turbines cannot meet the installation requirements of the wheel hub that is always in a rotating state during work, and can only be placed in the engine room, resulting in only hydraulic sliding The ring and the long-distance pipeline connection have a complex structure, are prone to leakage, and are inconvenient to maintain.

AI Technical Summary

Problems solved by technology

[0005] Because there is a heavy hammer connected under the swivel joint, under the action of gravity, it is easy to cause the joint between the swivel joint and the pipe to deform, thereby causing leakage

Moreover, when the tank body of the rotary oil tank rotates, the rotary joint will rotate around the rotation axis of the tank body while rotating by itself, and leakage between the rotary joint and the tank body is likely to occur
