Abstract

The invention discloses an offline filtration system for a high-precision wind power gear box. According to the technical scheme, the offline filtration system for the high-precision wind power gear box comprises a filtration device which is connected with a gear box of a wind driven generator to form a filtration circuit; the filtration device comprises a filtration component and a motor pump component connected with the filtration component; a pressure switch and an oil discharge valve are connected to the filtration component; a bypass relief valve is connected to the motor pump component.The technical problem that the safety problem is likely to be caused on the condition that a filter element is not replaced in time is solved. The system has the advantages that the bypass relief valve connected to the motor pump component can be opened when the pressure reaches 2.8 bar, and therefore safety overflow can be achieved when the oil pressure further rises, and the phenomenon that equipment is damaged is avoided.

Description

technical field [0001] The invention relates to a filter system, in particular to an off-line filter system for a high-precision wind power gearbox. Background technique [0002] Due to the shortage of resources and the government's policy encouragement and support for renewable energy, the development momentum of the wind power industry is strong. Due to technical deficiencies, failures will inevitably occur during the operation of the wind power generating set. Among the components, the downtime caused by the failure of the gearbox is the longest, and the main reason for the failure of the gearbox is that the gear lubrication effect is not good. [0003] At present, the Chinese patent whose notification number is CN201386631Y on the market discloses a kind of lubricating oil filtration system of a wind turbine gearbox, which includes a gearbox, a coarse filter, a filtering device, an A-type oil pump and a B-type oil pump. [0004] In the above scheme, the filter device an...
