What types of compressors exist?

Powers needed to operate equipment.
A compressor (compressor) is a portable device that deals with the conversion of engine electricity into compressed gas energy. It is used for a variety of tasks - both in the ordinary household and in developed industrial plants. The purpose of this device is to increase air pressure. First, the energy supplied to the electric motor is converted into kinetic energy by a shaft movement, which in turn drives the compressor block. This energy is then converted into compressed gas energy. It is worth remembering that each unit must be...

What is the difference between soft soldering and brazing?

soldering during soldering
We need soldering when we want to repair electronic equipment, but not only. We can also join metal plumbing components together or use the process for flashings. It is a very useful skill when we need to join two materials together. Then we can be sure that the connection is permanent and will not break so easily. To a large extent, we distinguish between two types of soldering - soft soldering and brazing. How do they differ and where do we use each? You will find out by reading this article. Soft solderingThis type is characterised by a soldering temperature ...
