Adjusting method for turbine gasket of vaneless turbine and turbine

Abstract

The invention discloses an adjusting method for a turbine gasket of a vaneless turbine, wherein disc bodies of a pressure difference vaneless turbine are smooth disc bodies, the turbine gasket is arranged between any two disc bodies, and the turbine controls the inlet or outlet track of a fluid working medium through the turbine gasket with a specific geometric figure. The method comprises the steps: detecting working medium gas before entering the turbine to judge the type and the attribute of the fluid working medium; calculating possible output power according to the type and the attribute of the fluid working medium; detecting actual output power, and meanwhile, comparing the obtained actual output power with the calculated output power, and if the actual output power is smaller than the calculated output power and reaches a first preset value, stopping work of the vaneless turbine; after the vaneless turbine is stopped, taking the actual output power as an input value, and recalculating parameters of the gasket, wherein the parameters of the gasket comprise the flow guide structure and the thickness; and replacing the turbine gasket according to a calculation result.

Description

technical field [0001] The invention relates to the technical field of turbines, in particular to an adjustment method for a bladeless turbine gasket and the turbine. Background technique [0002] The principle of the bladeless turbine pulling the turbine is the boundary layer effect of the fluid. The fluid is affected by the viscous force and will form a thin boundary layer on the edge of the pipe wall or other objects. In the boundary layer, the fixed surface The velocity of the flow is 0, and the velocity increases the farther away from the surface. Using this effect, the high-speed moving liquid can drive a set of discs to rotate. It is therefore much more efficient than a normal bladed turbine. [0003] The vaneless turbine driven by fluid shear force has the characteristics of simple structure, relatively low manufacturing tolerance requirements, and outstanding sealing performance. During operation, the fluid will generate a pressure gradient (positively correlated ...

Problems solved by technology

[0006] However, although the smooth disk of the turbine can reduce the difficulty of production, it is not the optimal deployment method. The disk body is improved, and the output power of the radial bladeless turbine through the pressure difference is higher than that of the traditional bladeless turbine. Great improvement, but the improvement of the disc body will lead to greater difficulties in the processing of the disc body, which increases the production cost

At the same time, due to different working media, the requirements for diversion are also different. If the diversion channel involved is fixed on the disk body, it is not conducive to obtaining the maximum performance.
