The invention relates to steam turbine installations and can be used in the cylinder block low-pressure (low-pressure) to the condenser.Most of the known steam turbines building module has a supporting belt for bearing on the Foundation of the turbine hall, and a condenser with a spring bearings for mounting on the Foundation of the basement under low-pressure. Between LPT and the capacitor is rigid connection welded connection between the outlet pipe and the neck of the capacitor  In such a steam turbine installation is provided free in the vertical direction of thermal re the outside of the module, cause harmful vertical component of the load on the module housing, wholly perceived in this case, and when filled capacitor his weight is perceived mainly support belt housing module, which leads to the necessity of its significant enhancement to correct deformities resulting in change of the gap in the flow part.Known steam turbine with a different execution unit module with a capacitor, which is the closest analogue of the invention. In this block housing LP cylinder is connected to the condenser through the expansion joint, and in addition, they are connected by a rigid link, the transmitting vertical forces from the excess of atmospheric pressure acting on the low-pressure cylinders, the body of the capacitor  the Capacitor of this block is mounted directly on the Foundation of the basement without the use of elastic supports, but due to its connection with the housing through the low-pressure compensator is provided by freedom of vertical movement module without exposing it to the masses of the capacitor. Furthermore, this rigid connection allows to compensate the excess of atmospheric pressure on low-pressure cylinders. However, this connection is made in the form of elastic elements on the capacitor and lever mechanizmust service associated with the control of tightness in hard to reach places, and increases the likelihood of leaks in the condenser.The basis of the invention is the task of creating such a unit module and the condenser, in which their relationship, providing freedom of vertical thermal movement low-pressure, however, would be unloading the module housing from the vertical action of excess of atmospheric pressure and the weight of the condenser and thus would be relatively simple to manufacture and maintain.This problem is solved in the block module with a capacitor, in which case LP cylinder is connected to the condenser through the expansion joint and through the hard link, transmitting the capacitor vertical force from the excess of atmospheric pressure acting on the low-pressure cylinders, and in which, in accordance with the invention, the module housing is made with a movable cover connected to the building through another compensator, and a hard link is made in the form of spacer rods between the cover module and the condenser.With this solution, as known, is provided free vertical thermal offset module, and in addition, as in the nearest analogue LP cylinder is not exposed to the masses to the condenser through the spacer rods is provided offload module from excessive air pressure in the vertical direction is the most simple way, do not increase the complexity of care and does not reduce the reliability of the unit.The invention is illustrated by a detailed description of one of the examples of its implementation, shown on the accompanying drawing, which pokazivaet General view of the block module with a capacitor, represented for clarity without rotor and internal stator parts module.The example relates to a steam turbine with double-flow low-pressure cylinders 1, made with a horizontal connector and supported by the legs 2 on the base 3 of the machine hall of the turbine. Under low-pressure cylinders in the basement of the installed capacitor 4, which is based directly on the base 5 in this room.According to the invention LPT 1 is made with a movable cover 6, which is connected with the housing through the low-pressure compensator 7, ensuring their mutual mobility. Connection module with capacitor 4 is implemented using a different compensator 8, providing mutual mobility module and the capacitor 4. While the perimeters of joints 7 and 8 are approximately the same. With capacitor 4 is connected also cover 6 module. This connection is effected via a number of spacer rods 9 passing inside the module and the capacitor 4.When working turbolenza above the pressure inside the module. This can lead to undesirable displacement of the module in the vertical direction. However, in the above example, the vertical component of the load on the module housing from excessive atmospheric pressure is transmitted from the cover 6 through the terminals 9 to the condenser 4, and thus its negative impact is neutralized. However, due to the presence of joints 7 and 8 are free thermal expansion of the module and thus the exception of deformation loads. In addition, due to the compensator 8 and installation of capacitor 4 on the Foundation 5, weight condenser with circulating water is fully transferred to the Foundation 5, without any effect on the low-pressure cylinders. This improves the working conditions of low-pressure, preventing it from bending and ensuring conservation gaps in the flow part. In addition, reduces the load on the Foundation of the turbine hall and its columns.It should be clear that the invention can be implemented in other ways than shown in the drawing example. In particular, it can be used in a single-threaded module, the movable cover may have a different shape spacer rods can be located with a crossed or as they may be used an equivalent hard elementia steam turbine.

SUBSTANCE: invention can be used at mounting of heavy-weight condensers of steam turbines connected with several exhaust ports of steam turbine low-pressure cylinders. 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.
EFFECT: improved reliability end economy of turbine.
