For a good standard, the bulb type turbine generator bearing support, the center of the iced tea should be 1mm or less. A bulb-type hydrogenerator refers to a hydrogenerator in which the generator and bearings are arranged in a sealed bulb-shaped shell. The bulb-type hydrogenerator is connected to the right axis of the turbine and arranged in the flow channel. It is characterized by a compact and complex structural layout and special requirements such as moisture and leak proofing. Since the bulb type hydrogenerator is installed in the underwater flow channel, the windings are easily affected by moisture when shut down, so its rated voltage is lower than that of ordinary hydrogenerators.
Lower voltage is better.
Red LED 5 mm, 1.8 V, 20 mA. This means that the LED is 5 millimeters in diameter and does not requireonly 1.8 volts and 20 milliamps of current to emit light. In fact, less than 20 milliamps of current can cause the LED to glow slightly.
