<P>PROBLEM TO BE SOLVED: To provide a device and method for detecting the clogging of a pressure guide pipe for detecting clogging on a low-pressure side, clogging on a high-pressure side and clogging on both sides by simple constitution requiring no reference value. <P>SOLUTION: The device for detecting the clogging of the pressure guide pipe includes a pressure detection means 5 for detecting the static pressure on the high-pressure side transmitted through a high-pressure side pressure guide pipe 3a, the static pressure on the low-pressure side transmitted through a low-pressure side pressure guide pipe 3b and the differential pressure between both static pressures, a differential pressure rocking calculation means for calculating differential pressure rocking on the basis of the time series data of the differential pressure, a high-pressure side static pressure rocking calculation means for calculating high-pressure side static pressure rocking on the basis of the time series data of the static pressure on the high-pressure side, a low-pressure side static pressure rocking calculation means for calculating low-pressure side static pressure rocking on the basis of the time series data of the static pressure on the low-pressure side, and a clogging determination means 400. <P>COPYRIGHT: (C)2011,JPO&INPIT |
