Abstract

The invention discloses a low temperature type wind power generator accelerator oil lubricating system being able to start up under the condition of low temperature. The lubricant in the system enters an electric pump and a mechanical pump after being heated by a heater; the outlets for the electric pump and the mechanical pump are both connected to an oil filtration device; the oil filtration device is communicated with the accelerator via a pipeline system configured with an oil cooling device; the pipeline system comprises a normative open passage and a startup passage connected in parallel; the oil cooling device is positioned on the normative open passage. The normative open passage and the startup passage can switch automatically via a startup one-way valve and a normative open one-way valve; an ultra low pressure one-way valve on the normative open passage is able to provide accident protection for a high-speed axle of the accelerator; a pressure sensor can control the motor of the electric pump via a control circuit, so that the electric pump can supply oil to the system on demand. Therefore, the invention, which enhances the reliability and service life of equipment, can be best applied for the wind power generator system in harsh cold region.

Description

technical field [0001] The invention relates to a wind power generator speed increaser, in particular to a low temperature type speed increaser oil lubrication system. Background technique [0002] At present, all wind turbine speed increasers are equipped with a lubrication system to perform forced lubrication on the moving parts in the speed increaser, and to filter and dissipate the oil. There is only one set of pipeline system in the oil lubrication system of speed increaser used at home and abroad, and there are two main forms: one is only electric pump; the other is when there is electric pump and two-way mechanical pump, the electric pump Provide lubricating oil for the speed increaser for a long time, and the mechanical pump is only a supplement. The working process of the system is like this, the lubricating oil flows in from the inlet of the system, and enters the electric pump and the mechanical pump after being heated by the heater. The pipeline of the device i...
