Wind power generation is to convert kinetic energy of wind into electric energy, wherein the wind energy is clean and pollution-free renewable energy, and the wind power generator is gradually popularized in life production. In order to reduce friction loss generated when mechanical parts inside the wind driven generator are operated, a lubrication system for injecting lubricating oil is generally arranged in the wind driven generator, and the temperature around the unit of the wind driven generator is greatly changed because the unit of the wind driven generator is positioned at a higher position. The oil storage tank for storing lubricating oil in the traditional lubricating system has no temperature regulation function, the temperature of the lubricating oil is greatly influenced by the environmental temperature of the unit, and the lubricating oil in the oil storage tank cannot be kept at proper working and storage temperature, so that the normal operation of the lubricating system is influenced.
When the environment temperature of the unit is higher, the temperature of the lubricating oil in the oil storage tank is also increased, the lubricating oil is slowly oxidized and becomes black at high temperature, and finally the oxide can not be dissolved in the lubricating oil, but is deposited at a certain position of the system in a brown mucus layer, so that a control oil duct in the oil pump is easily blocked, and the normal operation of the lubricating system is influenced. And the viscosity of the lubricating oil is reduced along with the temperature rise, so that an oil film is difficult to build, and the lubricating effect on mechanical parts in the wind driven generator is reduced.
When the environmental temperature of the unit is lower, the temperature of the lubricating oil in the oil storage tank is also reduced, the viscosity of the lubricating oil is increased along with the reduction of the temperature, and the more the lubricating oil with higher viscosity enters the oil pump, the more the adhesive films generated in the piston ring area, the piston skirt and the inner cavity of the oil pump are, the power of the oil pump is intermittently increased, and the loss of the oil pump is accelerated.
In view of this, it is necessary to provide a temperature adjusting device for adjusting the temperature of an oil storage tank in a wind turbine and a wind turbine, in order to solve the problem that the oil storage tank in the wind turbine cannot be kept at a proper working and storage temperature.
According to an aspect of the present application, there is provided a temperature adjusting device for an oil tank 1 in a wind power generator, the oil tank 1 having an axial direction and a circumferential direction with respect to the axial direction.
