Integral injection molding process for small household wind turbine blades
The small household wind turbine rectifies the unstable alternating current generated by the generator into a direct current to charge the battery through the inverter controller, thereby preventing the battery from overcharging, overdischarging, overloading and short circuit; and simultaneously providing the unloading channel to the generator to Protect the battery and generator; finally convert the DC power into a stable AC power supply for the user.
Blades are the key moving parts of small household wind turbines, directly affecting the performance of the entire system. It is necessary not only to have weather resistance for long-term use in the outdoor natural environment, but also to have a reasonable price. Conventional composite wind turbine blades are mostly manufactured by hand lay-up process, manual operation, and open mold forming. There are many problems in the quality of the blade produced by the process.
The blades in existing small household wind turbines can be RTM. Firstly, a pre-formed body of reinforcing material designed according to performance and structural requirements is placed in the cavity, and a special low-viscosity injection resin is injected into the closed cavity by using an injection device. The mold has a sealing, fastening, injection and exhaust system to It ensures that the resin flows smoothly and discharges all the gas in the cavity, and the heating system can be heat-cured.
The small household wind turbine blades produced by the RTM process have the characteristics of high dimensional and shape precision, high surface finish, strong mechanical properties, high molding efficiency and environmental pollution, and related technologies have been widely used.www.titanwindturbine.com
