for thrust balancing.
They are the same thing.
The balancing line is a transmission line consisting of two conductors of the same type, that are grounded to the compressor's circuits and to the ground and helps keep external noise down.
Usually not. The seals in a rotary that does the job of the piston rings in a piston engine have a much harder job to do, and tend not to last as long. Agreed. The "Wankel" was a good concept, an engine with one moving part but never lived up to it's potential. The above answer is an excellent example. The trouble mostly came from balancing the rotor, as it did not rotate in a perfect 360 degree circle and oil seals were prone to failure
The balancing disk is fixed to and rotates with the shaft. It is separated by a small axial clearance from the balancing disk head, or balancing sleeve, which is fixed to the casing. The leakage through this clearance flows into the balancing chamber and from there either to the pump suction or to the vessel from which the pump takes its suction. The back of the balancing disk is subject to the balancing chamber back pressure, whereas the disk face experiences a range of pressures. These vary from discharge pressure at its smallest diameter to back pressure at its periphery. The inner and outer disk diameters are chosen so that the difference between the total force acting on the disk face and that acting on its back will balance the impeller axial thrust. If the axial thrust of the impellers should exceed the thrust acting on the disk during operation, the latter is moved toward the disk head, reducing the axial clearance between the disk and the disk head. The amount of leakage through the clearance is reduced so that the friction losses in the leakage return line are also reduced, lowering the back pressure in the balancing chamber. This lowering of pressure automatically increases the pressure difference acting on the disk and moves it away from the disk head, increasing the clearance. Now the pressure builds up in the balancing chamber, and the disk is again moved toward the disk head until an equilibrium is reached. To assure proper balancing in disk operation, the change in back pressure in the balancing chamber must be of an appreciable magnitude. Thus, with the balancing disk wide open with respect to the disk head, the back pressure must be substantially higher than the suction pressure to give a resultant force that restores the normal disk position. This can be accomplished by introducing a restricting orifice in the leakage return line that increases back pressure when leakage past the disk increases beyond normal. The disadvantage of this arrangement is that the pressure on the seal chamber is variable, a condition that may be injurious to the life of the seal and therefore should avoided.
Frederick William lanchester invented the earliest MPFI engine
Leveling and balancing technique is also known as production smoothing. It is important so as to avoid waste in resources and in order to achieve efficiency in the production process.
