Invention can be used also at servicing and subsequent adjusting of steam turbines especially, high-power ones. Invention improves reliability and increases economy of turbine in operation owing to decreasing excess loads on exhaust parts of low-pressure cylinders and support foundation plates of exhaust parts from side of condenser, decreasing friction forces along support surfaces of low-pressure cylinders, deformation of supports, formation of cracks and increasing vibration stability of turboset at different loads and modes of operation. According to proposed method of mounting of steam turbine condenser connected with several exhaust ports of low-pressure cylinders including assembling, preliminary truing, welding of connecting branch pipes and fixing in space by means of calibrated setting strips under springs. After operation of turboset under load, position of condenser in space is corrected to reduce load on support belt of low-pressure cylinders by disconnecting exhaust branch pipes of turbine and condenser, filling condenser with water of designed mass, placing inserts between upper and lower branch pipes of designed mass, placing inserts between upper and lower branch pipes and subsequent connection of branch pipes of turbine and condenser. Disconnected condenser is filled with water whose mass corresponds to designed load ΔG taken from low-pressure cylinder which is determined by value of compression Δh of spring unit under each support of condenser, basing on its rigidity characteristic K. ΔG removed from low-pressure cylinder is =ΣΔh x K. Estimation of loads on support belt of low-pressure cylinders in process of complex tests is carried out by displacement pickups checking compression of spring under all supports of condenser, and grade pickups on built-in supports of low-pressure cylinders operating at continuous monitoring by means of processor-based devices.
