Turbine honeycomb seals optimization methods


g - O. 0600.20.40.60.811.2 ratio Figure 7 steam and gas turbine efficiency on 5 Conclusion (1) gives the mixture of gas and water vapor molar thermodynamic properties derived. And that gas and water vapor mixture gas constant, specific heat with the steam / gas ratio changes with changes in large adiabatic index with steam / gas ratio changes little change. (2) For a certain type of turbocharger turbine inlet were calculated after the injection of water vapor, water vapor flow rate obtained with different air flow turbocharger, supercharger and turbocharger pressure ratio of rotational speed: steam and gas the bigger the ratio the higher the speed of the turbocharger, the greater the compressor air flow,[link widoczny dla zalogowanych], compressor pressure ratio is higher; steam and gas, but not too large,[link widoczny dla zalogowanych], otherwise the turbocharger speed will exceed the limit. Temperature steam injection on the compressor pressure ratio to a certain extent, and the lower the temperature, pressure ratio increase is smaller. (3) of a certain type of turbocharger is calculated, obtained with different ratios of steam and gas turbine flow curve, the results show that: the low condition, the injected steam turbine, the turbine of the equivalent flow, expansion are larger than can meet the turbocharger turbine requirements. Conditions in the Engineering, the injection of steam turbines, the operating point moves to the block point, and the greater the steam and gas, equivalent to the higher speed, the expansion ratio, equivalent to the smaller flow rate can be increased. The same turbocharger turbine efficiency curve obtained, the results showed that: the steam and gas turbine efficiency characteristic curve was less affected.

(He Jingfang Edit) 'turbine honeycomb seals optimization method, according to \rotating parts and stationary parts leakage between the various space-related losses. Labyrinth seals with the traditional than the honeycomb seal has many advantages. Quality of the materials it is under the minimum guarantee seal with the greatest intensity, allowing application of high-pressure lowering, not increasing the size of seal. In addition,[link widoczny dla zalogowanych], it simplifies the turbine assembly installation and repair work. Honeycomb seals is characterized by the process flow in a honeycomb wall flow channel of the physical nature of the decision. Honeycomb structure,[link widoczny dla zalogowanych], the geometry of the structure should be based on these factors and reflect the impact of state parameters to optimize the multi-factor test. Turbo-machinery flow path in the use of honeycomb seals value in reducing the radial clearance, and sealed by means of optimized geometrical parameters of the relationship between cellular chamber significantly increased the economy of the turbine machinery. ; Core j (Ji Guiming feed)
