Pipeline compensator

1、 Scope of application:
The pulverized coal pipeline compensator is suitable for the compensation of thermal expansion and cold contraction of powder medium in pulverized coal conveying, pulverized coal feeding and exhaust gas pipelines of power plant station, and ensures no dust leakage.
2、 Advantages:
Most of the existing powder medium compensators in power plants are sleeve type compensators. The working principle of the compensators is that the packing in the packing box is used as the packing of the sealing body. After being compressed by the packing gland, it expands to all the gaps in the packing box, so as to realize the isolation of the medium in the pipe from the atmosphere. After several thermal expansion and cold contraction cycles, a gap will be left between the packing and the inner and outer walls of the packing box. The dust in the pipe will leak into the atmosphere through the gap, or burst due to the accumulation of powder. The leaked dust not only pollutes the air, but also accumulates on the ground and cable tray, which is harmful to environmental hygiene and may cause fire.
The inner wall of the pipe is made of rare earth alloy, which is not easy to be damaged by the hot expansion of the pipe.
The new non leakage dust pipeline compensation has the following characteristics:
1. It has three functions: easy expansion and contraction; tight and no leakage; anti-corrosion and wear-resistant.
2. It is easy to install without maintenance. Three years (30000 hours) of dust leakage can be guaranteed in the system (one overhaul period).
3. The patented design does not accumulate powder in the compensator.
4. It has good flexibility and rigidity, can absorb the expansion and contraction of three-dimensional direction, and has good flexibility to ensure the boiler and pipe system to expand freely.

4、 Connection type of expansion joint:
There are two types of expansion joint connection: one is direct welding of nozzle, the other is flange connection.

In the figure, 1 is the short connection, which can be installed into the system after welding with the flange; 2 is the flat welding steel flange of Pg6 and dg250; 3, 4 and 5 are the tightening parts of fixing wear-resistant bushing 9; 6 and 7 are the lead-in customers of sealing machine, and 8 are half wave joints.
The compensation of the compensator can be selected. In this drawing, 10 waves are used and the compensation is 100 mm. The inner bushing protects the wave node from being scoured, and the elasticity of the wave node solves the compensation of expansion and contraction. Generally, a ring seal is installed on the compensator, and the sealing wind is introduced during the operation, and the medium flowing into the wear-resistant sleeve and wave node is carried away by the wind direction.
5、 The main factors that must be considered in the selection of expansion joint are as follows:
The nominal diameter DN of pipeline, the interface size or flange standard and its connection size.
1. Working pressure P.
2. Working temperature T.
3. Medium properties.
4. The amount of compensation.
5. Life - consider service life or overhaul and replacement cycle.
