What is a swivel?

What is a swivel?

The rotary joint is the connection sealing device that injects the fluid medium from the static pipe into the rotating or reciprocating equipment and then exhauts it from the rotary joint, referred to as "rotary joint". The earliest rotary joint was a packing type seal, in the rotating part wound with hemp rope or asbestos rope type of filler. Because of the long working time to constantly replace the filling, in order to avoid such trouble, so someone invented the sealing wear parts. This is the prototype of the rotary joint today. Later, people use plane device, using silicon carbide to effectively solve the problem of plane wear.

There are two ways of electromagnetic disturbance on cable: magnetic field coupling and electric field coupling

There are two ways of electromagnetic disturbance on cable: magnetic field coupling and electric field coupling

In the electromagnetic compatibility test of electronic equipment, many projects are carried out for the equipment's external tow cable. This is based on the effect of electromagnetic fields on electronic equipment, the main manifestation of which is the generation of an induced voltage on a long cable.
