Attenuator 2W N type has the following basic uses: 1) Control power level: Control the output power of local vibration in the microwave superheterodyne receiver to obtain the best noise factor and frequency conversion loss to achieve the best receiving effect. In microwave receiver, automatic gain control is realized to improve the dynamic range. 2) Decoupling element: as a decoupling element...

Currently, there are three main ways for tuya bulb light supplier to achieve white light: 1. Synthesize white light through tuya bulb light supplier's three-color multi-chip set of red, green and blue and glow. Advantages: High efficiency, controllable color temperature, good color rendering. Disadvantages: the three base color light decline is different resulting in unstable color temperature,...

In order to understand how it works, we need to know its structure first. It is mainly composed of four parts, namely import and export mufflers, which are designed to reduce the noise of cyclone function. The second is the impeller, which is closely related to the working principle of cyclone function. The third is the wall board, which is mainly used for connection and support. And finally,...

The workshop's centralized dust collection system has three options for centralized dust collection system: dust, that is, like all diseases, prevention is always better than treatment. For example, a flow trough is added during material handling, belt transfer, so dust, or dust generation and handling can be greatly reduced; In the treatment of steel slag and other loose materials, the use of...

After the dust -containing gas enters the dust collector ash bucket, due to the sudden expansion of the airflow section and the function of the airflow distribution board, some large particles in the airflow are settled on the ash bucket under the action of moving and inertia; Through the combined effects of Brown diffusion and sieve filter, the dust is deposited on the surface of the filter...
