Corrosion resistance testing system for wind power cooler core

Abstract

The invention discloses a corrosion resistance testing system for a wind power cooler core. The testing system comprises a testing device and a control system. The testing device includes a cooler core body, a pressurizing device, a monitoring device, a corrosive gas generating device, a temperature and humidity generator and a sunlight ultraviolet simulator. The corrosive gas generating device, the temperature and humidity generator and the sunlight ultraviolet simulator are connected with the control system through circuits. The control system includes a signal converter, a PLC controller, ahuman-computer interface and a frequency conversion control device; the signal converter is connected with the PLC through a circuit; and the PLC controller is connected with the human-computer interface and the frequency conversion control device through circuits. Therefore, the corrosion-resistant performances of various cooler cores in different environments can be efficiently and quickly tested; and the medium leakage and replacement and shutdown losses of the fan after corrosion can be reduced and the time of continuous operation time of the fan is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of coolers, in particular to a system for testing the corrosion resistance of a wind power cooler core. Background technique [0002] The core of the cooler is the most important part of the wind power lubrication and cooling system. It mainly cools the heat-generating components such as the wind power gearbox, generator and frequency converter, so that the wind power generation equipment can always maintain normal operation within a reasonable temperature range. Usually, the wind power cooler core is installed inside the nacelle or outside the bottom tower, which is greatly affected by corrosive gases in the atmospheric environment or sunlight ultraviolet rays, and the corrosion resistance of the cooler core is required to be high. Once the core of the cooler is corroded, it will have a great impact on the fan. On the one hand, the system pressure is low due to the leakage of the wind power lubrication and cooling sy...

AI Technical Summary

Problems solved by technology

Once the core of the cooler is corroded, it will have a great impact on the fan. On the one hand, the system pressure is low due to the leakage of the wind power lubrication and cooling system, which makes the gearbox, generator and frequency converter unable to work normally; on the other hand, The liquid leaked from the cooler core will pollute the fan and even the surrounding natural environment

Therefore, the cooler core is required to have high corrosion resistance during use, but the existing salt spray test and other methods cannot fully test the corrosion resistance of the cooler core in the real environment
