Abstract

The invention discloses a sampling device for fan gearbox lubricating oil and a use method thereof, and belongs to the technical field of operation and maintenance of wind turbine generators. Comprising a conduit, a top cover, a three-way pipe body, a sampling bottle, a piston, a piston cavity and a guide rod, the top cover is connected with a joint of the oil drain valve; the three-way pipe body is respectively connected with the top cover, the sampling bottle and the piston cavity in a sealing manner, and an oil retainer is arranged on the inner wall of the three-way pipe body; one end of the conduit penetrates through the top cover and the three-way pipe body and extends into the sampling bottle, and the other end is exposed out of the top cover and is hermetically connected with the top cover; the piston is arranged in the piston cavity and connected with the guide rod. The device is reasonable in structural design, the negative pressure principle is utilized, the flow guide speed and flow of a sampled oil product can be accurately controlled in a piston extraction mode, and the risk that the oil product leaks and is polluted is effectively avoided. The working efficiency and convenience of oil sampling are improved, the oil change trend can be mastered in time, the operation conditions of a gear box and the like can be judged in time, and the operation safety and stability of a wind turbine generator are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wind turbine operation and maintenance, and in particular relates to a sampling device for lubricating oil of a wind turbine gearbox and a use method thereof. Background technique [0002] Since the friction parts of the transmission system of the wind turbine bear huge loads and transmit huge torques, all moving parts such as bearings and gears of wind power equipment are under the working conditions of frequent start-stop and high-load continuous operation. Lubricating grease is used in the mechanical contact between various transmission gears and bearings of the fan, forming an oil film on the contact surface to reduce friction and wear, prolong the service life of the machine, and also play a role in cooling, rust prevention, corrosion prevention, cleaning, sealing and buffering And so on. Therefore, the performance detection of lubricating oil is very important in the later operation and maintenance...
