Description

(54) SUPPORT DEVICE UNDER TURBOAGREGAT

    . .

The invention1 relates to foundation building, namely to the structural foundations for turbine units. l

Supporting devices are known for different aggregates, in which a hydraulic system of tanks connected by the pipeline system 1 is used to correct the uneven draft of the supports.

However, the known devices do not provide vibration isolation of the unit from the foundation and do not allow the unit to be kept at a constant level.

The closest technical solution to the invention is a support device for a turbine unit, including a support plate for installing a turbine unit, a laid base and a base located between the base and the support base plate, each of which is provided with a resilient element and a working medium filled with a capacity that can accommodate all supports. } between each other pipe system 2.

In the known device, the elastic elements - the springs are arranged parallel to the capacitance m

and develop only 1 fi pressure drop in them. These springs are not provided. tavayet effective damping of the vibration of the operating unit. The design of the known device does not allow maintaining a constant design level of the unit.

- The purpose of the procurement is to ensure the possibility of maintaining the project level

support pin, as well as damping, vibration of different frequencies. Specified Target of others |}

An inclusive base plate for the installation of a turbine unit, a base laid on the base and placed between the base and the base plate O1ure, each of which is provided with an elastic element and filled with working medium with capacity, and the capacity of all the supports are interconnected by a piping system, but with a source pressure connected to the piping system, and shut-off and control devices installed on the pipelines, and each elastic element is placed above the corresponding volume 3. yostyo or under it. Each support can be equipped with 5G1a limiters of i-horizontal and vertical movements. FIG. 1 shows a diagram of the proposed device; on fit. 2 is a diagram of one of the supports. The device contains a base 1, on which several vertical supports 2 are located. On support 2 a common support plate 3 is supported. On each support 2 there is a container 4 filled with working medium, which is pneumatic or hydrocompensated. All containers 4. are connected to the pipeline 5, on which there are locking and regulating devices 6, filled in the form of check valves. The pipe wires 5 unite the tanks 4 into a constant pressure system equipped with a pressure source 7, the supports 2 are provided with limiters 8 vertical and horizontal displacements Between the support plate 3 and each, the support 2. cat springs. The device works as follows. The pressure source maintains constant air pressure in the hydraulic valves (hydros compensators), due to which the force taken by each KOMniBHTOTOpOM from the base plate remains constant and does not depend on base deformations. With uneven base deformation, the volume of compensators located in places of greater base sediment increases. The system automatically receives an additional volume of working medium from the pressure source, and the support plate remains at the same level. To avoid skewing of the support plate with its possible uneven loading Each compensator is separated from a common system by a check valve. Vertical damping of different frequency vibrations from the unit's work
