Product principle：

The no thrust telescopic device, is the use of the PASCAL theory in fluid mechanics, in the design structure of the clever use of a dense annular steam chamber, the steam chamber has two annular compression surface, one is a fixed steam chamber end face, the other is closed in the steam chamber telescopic tube shoulder ring surface, with the telescopic tube is mobile. The area of the movable annular compression surface is equal to the cross-sectional area of the telescopic tube. When the telescopic device works, under the action of medium pressure, the pressure on the annular surface and the cross-sectional area of the telescopic tube are equal, and the direction is opposite, so the two pressures cancel each other. In this way, only the friction force of the telescopic packing is considered in the design of the bracket. In the thrust calculation of the fixed bracket, the thrust caused by the pressure of the working medium is no longer calculated. Therefore, the fixed bracket belongs to the load-reducing bracket, which can save a lot of bracket materials, manpower and financial resources.

Dc medium no thrust ripple compensator installation instructions：

(1) When the wall thickness of the pipe segment welded with both ends of the telescopic device is greater than or equal to 6mm, groove treatment should be carried out, and water pressure leak detection test should be carried out according to the requirements after welding.

(2) Sliding bracket and fixed bracket are installed according to the design, using ZTWB type, except for the thrust without calculating the working pressure of the medium, the rest of the same. In order to ensure that the pipeline has no lateral displacement and expands along the axis, both ends of the telescopic device should be installed with guide sliding supports, and fixed supports should be installed at the bend of the pipeline.

(3) The thermal insulation protection structure of the telescopic device is in the same way as the pipeline, but it cannot be binding on the telescopic part of the telescopic pipe.

(4) The telescopic device can be installed according to the * installation length LMax under various ambient temperatures, without stretching or compression.

Dc medium no thrust ripple compensator main technical parameters：

(1) Nominal diameter range of pipeline: DN25 -- 1000mm;

(2) Applicable nominal pressure range: PN≤2.5MPa;

(3) Applicable operating temperature: t≤350℃;

(4) expansion volume;

(5) Selection of telescopic device When selecting the telescopic device, the nominal diameter DN shall prevail. The outer diameter of the design pipe should be the same as that in the parameter table, and the allowable error is less than 3mm.
