There are many types of non-thrust compensators. Today we will take a detailed look at the ZTW type DC medium non-thrust compensator and two-way non-thrust sleeve compensator.
Features of ZTW type DC medium without thrust compensator
The thrust-free compensator is based on Pascal theory in fluidics, and uses a dense annular steam chamber in the design structure. There are two annular pressure surfaces in the steam chamber, one is the fixed inner end surface of the car, and the other is the annular surface of the shoulder of the telescopic tube enclosed in the steam room,which is movable with the telescopic tube. The area of this movable annular pressure surface is exactly equal to the cross-sectional area of the telescopic tube. When the compensator works, the pressure on the annular surface is equal to the pressure of the cross-sectional area of the telescopic tube under the effect of the medium pressure.In this way, only the frictional force of the compensator pressing the packing is considered in the design of the bracket, and the thrust on the fixed bracket is no longer calculated in the thrust calculation of the fixed bracket due to the pressure of the working medium.Therefore,the fixed bracket is a load-reducing bracket,which can save a lot of bracket materials,manpower and also financial resources.
Features of two-way thrustless sleeve compensator
No matter which end of the compensator flows in, the sliding sleeves at both ends of the compensator always slide freely to achieve the effect of bidirectional compensation and increase the compensation amount. The inner sleeve of the two-way non-thrust sleeve compensator is connected to the pipeline.It adopts the principle and structure of a high-performance self-pressing dynamic seal. It can slide in the shell with the expansion and contraction of the pipeline freely, and adapt to any pipeline sealing requirements. The shell and the inner cylinder are sealed with a new type of synthetic material,which can be withstand high temperatures, corrosion and aging. The skills ensure the medium in the pipe will not leak.
Bidirectional thrust-free sleeve compensator is a compensation device for hot fluid pipelines. It is mainly used for axial thermal expansion displacement absorption compensation after the auxiliary installation of linear pipelines. It is a non-corrosive unidirectional or multidirectional fluid directly installed in any tree hole.The two-way thrust-free sleeve compensator is widely used in transportation pipelines in urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries.
The bidirectional thrust-free sleeve compensator has a long service life, and the fatigue life is equivalent to that of the pipeline.The sliding surface is specially treated, and has good corrosion resistance in salt water, rock solution and other environments. At the same time, if the sealing effect is weakened due to wear after many years, the flange can be tightened again to enhance the sealing performance, or the bolt can be loosened, the pressure ring can be removed, and then one or two layers of seal rings can be installed and pressed circle and keep using.
