The method of detecting the freezing state inside the fuel circuit of the turbomachinery or the necessity of maintenance

摘要

The fuel circuit of the turbomachinery (1) the method of detecting the freezing state inside, metrical unit (10) from grasping the information which displays the 1st temperature T of the fuel of downstream side₁, step and the filter unit which compare 1st temperature T₁ with 1st base temperature T₀₁ when step and the reading temperature T_{1 which} (6) detect plugging up are under 1st base temperature T₀₁, when at the same time plugging up is detected, the fuel circuit (1) includes with the step which produces the signal which shows the freezing state inside. Although it approves or denies freezing state, or, the tank (3) the information which displays the 2nd fuel temperature T inside₂ being grasped, when reference level T_{02 it} is compared, it is. The signal which shows the necessity of maintenance of the fuel circuit grasps, and temperature T₁, T₂ base temperature T is₀₁ and T₀₂ or more, it is put out when plugging up is detected.
