Abstract

The invention discloses a wind turbine blade coating erosion and wear experiment table which is characterized by comprising a sand box, a sand separation device, a sand collection trolley, an erosion pipe, an air compressor, a flowmeter, a pressure reducer, an air valve, an erosion box and an experiment table rack, wherein the lower opening of the sand box is connected with the upper end of the sand separation device, and a sand quantity adjusting plate is arranged at the joint of the lower opening of the sand box and the upper end of the sand separation device; the lower outlet of the sand separation device is connected with a sand inlet in the front part of the erosion pipe; the front end of the erosion pipe is connected with the air outlet of the air compressor by virtue of the flowmeter, the pressure reducer and the air valve which are connected in series with one another; the rear end of the erosion pipe is connected with the inlet in one side of the erosion box; the devices, except for the air compressor, are arranged on the experiment table rack; and the sand collection trolley is arranged below the experiment table rack. The wind turbine blade coating erosion and wear experiment table disclosed by the invention has the advantages of being high in matching property, firm in structure, attractive in appearance, reliable in brake, safe to use, stable, convenient to maintain and durable in use.

Description

technical field [0001] The invention relates to a wind turbine blade coating erosion and wear test bench, which is used for simulating the erosion and wear of the wind turbine blade coating by sand-laden wind under different parameters such as erosion velocity, sand carrying amount and erosion angle. The wear process provides a real and reliable simulation environment for the erosion and wear research of wind turbine blades, and belongs to the field of wind power generation. Background technique [0002] With the gradual depletion of fossil resources, wind power technology has been vigorously developed in recent years. The blade is a key part of a large fan, and its cost accounts for about 20% of the fan. The central and western parts of Inner Mongolia have unique wind resources, but due to the deterioration of the surrounding environment, the wind carries a large number of sand particles, which seriously erodes and wears the coating of the fan blades under high-speed r...
