20 to 30 tonnes.
Fan blades have different specifications and weights. Generally speaking: current wind turbine blades are more than 80 meters high, the wind turbine blade nacelle cover weighs more than 20 tons, and the wind turbine weighs more than 20 tons. The blades are 90 meters high. The bladed nacelle weighs more than 30 tonnes.
Electric blades are the essential components of wind turbines that convert natural wind energy into wind energy. They also constitute the main basis for measuring the design and technical level of wind turbines. China's wind turbine blade market has formed major diversified investment forms such as foreign-funded enterprises, private enterprises, research institutes and listed companies.
2 MW wind turbine, lifting a weight of 95 tonnes. 2 MW wind turbine, blade length range : 48 to 59 meters, corresponding hub height 80 to 100 meters. The weight is approximately: 8 to 15 tonnes/blade.
A fan is a machine that relies on supplied mechanical energy to increase gas pressure and exhaust the gas. This is a fluid driven machine. Fan is the usual abbreviation for gas compression and transportation machines in China. Fans generally include ventilators, blowers and wind turbines.
Fans are linked to the transmission and distribution energy consumption of the system and are a very essential part of building energy conservation. According to years of fan testing by the National Air Conditioning Equipment Quality Supervision and Inspection Center, many fans have problems under rated operating conditions. Therefore, fans must be produced and manufactured in strict accordancetee with product standards.
When the fan starts to work, the vibration of the bearing part is very small. However, as the operation time increases, the dust in the fan adheres unevenly to the impeller, gradually destroying the dynamic balance of the impeller. the fan and gradually vibrating the bearing. Increase, once the vibration reaches the maximum allowable value of the fan, 11mms, the maximum allowable value expressed by the amplitude value is as follows, the fan should be stopped for repair.
