PFD Series DN50-22 Side-Mounted Oblique Tube Anti-Blocking Wind Pressure Sampler

Oblique tube anti-blocking wind pressure sampler

The inclined tube anti-blocking wind pressure sampler is classified as an anti-blocking sampler by our factory. This category includes other specifications of anti-blocking samplers produced by our factory. Below I will introduce the relevant information of the anti-blocking wind pressure sampler and the downward inclined tube.

1. Overview of power plant anti-blocking sampler

The oblique tube anti-blocking wind pressure sampler is mainly used to measure the wind pressure on the wind duct. It is widely used in the power, petrochemical and other industries. There are two main functions:

1) As the name implies, it plays the role of blocking and sampling. It can prevent impurities (dust and particles) in the pipeline from entering the wind pressure measurement pipeline and clogging the instrument. The utility model can prevent the instrument pipeline from being blocked and play a blocking role. Secondly, the transmitter collects the pressure signal through the anti-resistance sampler and performs the sampling function.

2) The anti-blocking sampler has a built-in anti-blocking mechanism, which can play a buffering role when the gas is input into the sampler, and has a certain shock absorption effect, thereby avoiding unstable wind pressure and causing fluctuations in the measured value.

2. Reasons for the existence of inclined tube anti-blocking pneumatic sampler

1) This utility model adopts a physical mechanism to achieve the anti-blocking sampling function, and the sampler needs to be installed vertically during installation. When the above installation is improper, it is necessary to measure the side of the pipeline through a section of extraction pipe while keeping the sampler still installed vertically.

2) During the replacement process, the instrument tube is still tilted in the sampler because it is just changing the sampler. In order to facilitate the connection, the replacement sampler can extend or add a section of tilted tube at the inlet of the original base.

3. Angle of oblique tube sampler for anti-blocking sampler in power plant

1) The angles are generally 45 degrees, 60 degrees, etc. (except 90 degrees)
2) If the customer has requirements, we can make orders according to the customer’s requirements.

4. Anti-blocking wind pressure sampler material

1) Material: Carbon steel, 201, 301, 304, 321, 316, etc., or other special materials can be customized (904, 2205, etc.)
2) Specifications: Can be customized according to shape, size, material to meet customer needs.
3) Signage: Our factory is mainly for customers, mainly channels (middlemen), if necessary, we can do OEM for them

5. Anti-blocking sampler installation instructions

1) Drill a hole in the flue, place the sampling tube into the flue, and make the sampling head flow in the direction of the smoke flow. (Depending on the situation, the factory can be equipped with an anti-wear sleeve.)
2) Weld the sealing flange to the flue and cooperate with the sampling tube welding to ensure sealing.
3) Connect the sampling tube and cyclone collector with a nut. Use a silicon tube to connect the measuring tube to the U tube.
4) The cyclone collector is connected to the extraction tube and valve, and the sampling system is connected to the position of the induced draft fan baffle (that is, a hole is opened here). Weld the tube to the weld
5) Heat the sampling system (outside the flue) and the entire steam trap to prevent condensation and clogging of the pipeline after sampling. Coal powder sampler, anti-blocking wind pressure sampler, anti-blocking sampler pfd
