Wind speed monitor is affected by the alpine climate

The accuracy of wind speed data has a very important influence on the formulation of cultivation measures for facility agriculture. The application of automatic meteorological stations during modern agricultural planting is very common. The sensor for measuring the wind direction velocity is composed of a single-wing wind direction wind sensor and a wind cup wind speed sensor. It is also often referred to as the wind speed monitor.

The wind direction detector wind sensor is a single-wing wind vane; the wind speed sensor is a three-cup sensor. The greatest threat to the normal operation of the automatic weather station in the winter half year is freezing due to rain, fog, etc., including freezing of the wind speed sensor and freezing of the rain sensor. Wind sensor ice icing and freezing is the result of comprehensive factors of temperature, humidity, wind speed and other meteorological conditions. The frequency of mixed ice accumulation of rain, fog, and fog is high, and the freeze time of the wind sensor is the longest and most harmful. The basic conditions and characteristics of severe ice coating are temperature. For -5 ~ 0 °C, the average wind speed ≤ 5m / s, air relative humidity> 80% of the freezing rain or heavy fog snow weather.

At present, most of the sensors (mainly wind-borne wind speed sensors and rainfall sensors) used in automatic weather stations in mountainous alpine weather stations and cold places in China have no heating devices. During the winter freezing period, the rain sensor (measurement of liquid precipitation and precipitation intensity) was stopped, and the wind direction wind sensor was suspended when it was frozen, and then used after thawing, causing sometimes no wind speed data for winter winds.

For the freezing of winter problems: to ensure that the wind direction wind speed monitor wind speed sensor and rain sensor can be used normally in winter, increase the wind direction sensor heating automatic control system and rainfall sensor automatic heating control system. Routine maintenance is equally important for the normal operation of automatic weather stations. The main task is to pay attention to checking whether the sensors are normal every day; check whether the power supply system is normal after a severe thunderstorm in the summer and see if the displayed data is abnormal (usually the red display). If it is abnormal, reset the collector in time. Monthly comprehensive inspection of the automatic weather station. Every year around March of spring, the lightning protection facilities of the automatic weather station will be fully inspected and tested for grounding resistance.

UCP Pillow Block Units

UCP Pillow Block Units(ucp pillow block bearings): Pillow block bearings,insert bearing with housing, flange bearing units, and plummer block all consist of a housing with a bearing mounted in it. They are available in a variety of materials, mounting configurations and various bearing features.It is simple to mounted bearing,each mounted unit acts as a system to position the bearing securely for reliable operation. Pillow block bearing is widely used in various of machinery, especially in food machine,and they also can be used into pharmaceutical machinery, conveyering systems, photo & film processing machinery, spin machine,dying & printing machinery,etc.

Maintenance:

Clean the bearing will be removed check, use methods such as taking pictures first record appearance. In addition, to confess the residual amount of lubricant and lubricant sampling, and then clean the bearing. Examination and distinguish can remove the bearings from scratch using, check on the accuracy for the standard, rotating accuracy, internal clearance and collaboration, raceway surface, insist on frame and seal rings etc. About the inspection effect that can be used by bearing or known bearing.
