Installation requirements for wind pressure anti blocking sampler

Wind pressure anti blocking samplerIt is made based on the principle of cyclone separator. The anti blocking wind pressure sampler has been proven by long-term use in power plants across the country to be capable of measuring wind pressure and differential pressure in viscosity and powder (coal powder) systems, as well as in furnaces, for high viscosity, low flowability, and highly corrosive air powder mixtures without blockage.

The wind pressure sampler is installed between the air supply duct and the wind pressure measuring instrument and transmitter, and has two main functions:

1. To prevent impurities (particles, dust, etc.) in the air from entering the wind pressure measurement pipeline and instruments, to avoid blocking the measurement channel, and to achieve the function of anti blocking;

2. Due to unstable wind pressure, the instrument display is unstable. After installing the sampler, it can provide a certain damping effect and improve the measurement effect. Installation requirements:

　　Wind pressure anti blocking samplerInstallation requirements: The sampler must be installed vertically on the process pipeline or equipment. When encountering difficulties, please extend the sampling tube. The extension tube should use a 11/2 gas pipe, and the angle between the extension tube and the horizontal plane should be greater than or equal to 60 °. The sampler itself still needs to be installed vertically. If conditions permit, use a 1/2 gas pipe to vertically extend the outlet pipe by 300mm, and then use a φ 14 × 2 seamless steel pipe to reach the instrument.

stainless steelWind pressure anti blocking samplerInstalled between the air supply duct and the wind pressure measuring instrument, wind pressure transmitter, it mainly has two functions: it can prevent impurities (particles, dust, etc.) in the air from entering the wind pressure measuring duct and instrument, avoid blocking the measurement channel, and has a certain anti blocking effect; Due to unstable wind pressure, the instrument display is unstable. After installation and sampling, the measurement effect can be improved and a certain damping effect can be achieved. Different forms of wind pressure samplers can be used for different locations of air duct blockage (dew point, pressure tap).
