Thermocouple box for measuring the gas flow temperature field

摘要

The utility model belongs to the field of technical physics, namely to the combs for measuring the temperature field of the gas flow and can be used to measure the temperature of the oncoming flow in the elements of gas turbine engines, for example, at the exit from the combustion chamber at a gas flow temperature exceeding 2000 K. The proposed useful model excludes the influence of the geometric shape of the heat receivers on flow conditions and allows to simplify the operation of the comb when mounting thermocouples in the case of the heat receiver, h as a result, it allows solving the problem of expanding the arsenal of technical means by creating a comb of thermocouples for measuring the gas flow temperature field exceeding 2000K. The essence of the useful model is the successive arrangement of heat receivers in the cooled case, made in the form of glasses with a streamlined bottom, and means for securing thermocouples in the form of reinforcing rods, on the outer surface of each of which there are evenly arranged on the circumference of at least four individual slots intended for placement of the corresponding thermocouples, which makes it possible to realize the purpose of the proposed utility model. The technical result is the realization of the purpose of a useful model, namely the creation of a comb of thermocouples for measuring the temperature field of a gas stream at temperatures in excess of 2000 K. 3 ill. which allows to ensure the implementation of the purpose of the proposed utility model.
