Introduction

My corporation has made scientific researches on the Blowing Device for Wind-Pressure Measuring for years，this installation acquired patent right(NO：200520139694.3).This installation settles the pivotal problem among the Blowing Device for Wind-Pressure Measuring.This Installation install a manostat，the manosta settles the problem of the unstable airflow’s headstream.

1、Main technical parameter

Instrument atmospheric pressure：≥0.6Mpa

Effect error ：Less than 1% of the relative difference

Inside Consumption：0～3m3/h(Adjustable)

Applied environment：-30～75℃

2、Structure And Principle

This installation is composed of two parts：the control box of invariable airflow、 the sampling and Blowing installation(installed the compensable installation inside，chart 1)。

4、Installation 

①  The control box of block-proof must be fixed in locale，the locale don’t acutely shake and environment’s temperature is low 75℃,and the locale isn,t corrosive。

②  The horizontal gradient of the pipeline that is used for sampling And blowing is high 30。When installing,The ektexine of the boiler is high the wall，the forepart of the pipeline that is used for sampling And blowing must put in the attemperator(20～50mm)。

③  The pipeline that connect the control box to the measuring point is stainless steel or seamless steel(φ14×2)。

④  When installing, the control box is perpendicular to the horizontal plane by all means，the pipeline of the airflow’s headstream must add a switch。
