Product Features

It utilizes Pascal's theory in fluid mechanics,Cleverly utilizing a dense annular chamber in the design structure, this chamber has two annular compression surfaces, one is the fixed end face of the chamber, and the other is the annular shoulder surface of the expansion tube enclosed in the chamber, which is movable along with the expansion tube. The area of this movable annular compression surface is exactly equal to the cross-sectional area of the expansion pipe. When the compensator is working, under the action of the medium pressure, the pressure on the annular surface is equal to the pressure on the cross-sectional area of the expansion pipe, but in the opposite direction, so the two pressures cancel each other out. The selected sealing fillers are all flexible graphite, and the grades used are nuclear grade and industrial precision grade. Some antioxidant components have been added to the compensator packing to delay the oxidation time of the packing, thereby greatly improving the sealing performance of the ZTWB DC medium thrust free compensator compared to ordinary compensators.

Product principle

The clever structural advantages of this designUse a sealed annular chamber, which has two annular compression surfaces, one is a fixed end face of the chamber, and the other is a shoulder annular surface of the expansion tube enclosed in the chamber, which is movable along with the expansion tube. The area of this movable annular compression surface is exactly equal to the cross-sectional area of the expansion pipe. When the compensator is working, under the action of medium pressure, the pressure on the annular surface is equal to the pressure on the cross-sectional area of the expansion pipe, but in the opposite direction, so the two pressures cancel each other out. In this way, when redesigning the bracket, only the frictional force of the compensator pressing the packing is considered. In the calculation of the thrust on the fixed bracket, the thrust caused by the pressure of the working medium is no longer calculated. Therefore, fixed brackets belong to load reducing brackets, which can save a lot of bracket materials, as well as manpower and financial resources.
