Description

Condenser staple bolt frock

Technical Field

The utility model relates to a condensing equipment specifically is a condenser staple bolt frock.

Background

In the thermodynamic cycle of the condensing steam turbine unit of the modern large-scale power station, the condensing equipment plays a role of a cold source and is used for condensing the steam discharged by the steam turbine into water and establishing and maintaining a certain vacuum degree at the exhaust port of the steam turbine. The condensing equipment comprises a condenser, a cooling water pump, a condensate pump and an air extractor, wherein the condenser is the most main component. The surface condenser commonly used at present mainly comprises a water chamber, a shell, a cooling pipe, a pipe plate, a hot well and other structures.

When the condenser operates, cooling water takes away heat through the cooling pipe, and steam outside the pipe is condensed into water. In order to reduce the vibration of the cooling pipe during the operation of the condenser and reduce the damage to the cooling pipe, a plurality of intermediate partitions are arranged in the condenser and used as supports for the cooling pipe. To circular condenser, the intermediate bottom all adopts the circular slab to just can assemble the welding after putting into it from the casing both ends of condenser, consequently circular condenser has higher requirement to the circularity of casing, and the casing that takes place deformation easily can bring very big inconvenience for subsequent baffle assembly, can't guarantee product quality.

The former small condenser has small diameter, so the deformation of the shell in the subsequent operation is not large. After the shell of the large circular condenser is rolled, the risk of large deformation often exists, particularly when the diameter of the shell exceeds 3.5m, the rigidity is obviously reduced, the possibility of deformation is greatly increased, after various openings are formed in the cylinder, the deformation caused by the openings is more obvious, and the installation of the intermediate partition plate is more difficult.

Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

As shown in fig. 1, a condenser hoop fixture comprises an outer frame and an inner support ring. The outer frame is formed by connecting a plurality of outer arc pieces 1, and adjacent outer arc pieces are fixed through fasteners.

The outer arc piece is the bent plate of transversal personally submitting T shape, including pterygoid lamina 1.2 and vertical fixation at the web 1.1 of the outer periphery of pterygoid lamina, the pterygoid lamina all is the arc bending with the web, is equipped with a plurality of symmetrical arrangement's regulation hole 1.3 on the pterygoid lamina of both sides of web, and the tip of web still is equipped with mounting panel 1.4, is equipped with a plurality of mounting holes 1.5 on the mounting panel. The fastener comprises a connecting bolt 5 and a connecting nut 6, the end parts of the two outer arc sheets are aligned, the connecting bolt penetrates through the mounting holes of the two mounting plates, then the connecting nut is screwed on, and the outer arc sheets can be connected end to assemble the outer frame.

The inner support ring comprises a plurality of inner arc plates 2 arranged inside the outer frame. The inner arc plate is arc-shaped and bent, the diameter of the inner circumference of the inner arc plate is matched with the outer diameter of a condenser 9, two adjusting screws 3 are vertically fixed on the outer circumferential surface of the inner arc plate, and each adjusting screw is also provided with two adjusting nuts 4. Two adjusting screw rods of each inner arc plate respectively extend into the adjusting holes which are symmetrical on two sides of the outer arc piece, and the adjusting nuts clamp the wing plates of the outer arc pieces to enable the inner arc plates to be fixed on the outer arc pieces.

As shown in fig. 1 and 2, the outer frame includes 3 outer arc pieces, a central angle corresponding to each outer arc piece is 120 degrees, each outer arc piece is provided with 4 pairs of adjusting holes (inner diameter is preferably 34mm), each mounting plate is provided with 4 mounting holes (inner diameter is preferably 34mm), and two outer arc pieces are fixed by using 4 connecting bolts 5 and 4 connecting nuts 6. A gap of 40-80mm is kept between the mounting plates of the two outer arc sheets for adjustment during connection. As shown in fig. 1, 2 and 3, the inner support ring includes 12 inner arc plates, 4 inner arc plates are disposed on each outer frame, and a central angle corresponding to each inner arc plate is less than 30 degrees.

The utility model discloses a theory of operation is:

during the use, select the inner arc board of suitable size according to the size of condenser casing, on installing the outer arc board with the inner arc board, use the fastener with outer arc piece annular outer frame, again with whole frock suit in condenser 9 outsidely, screw up adjusting nut and coupling nut at last, make whole frock tightly fix on condenser casing, just so can avoid the steam casing to take place outside deformation, effectively guarantee the circularity of casing. The distance between the inner arc plate and the outer arc sheet can be adjusted by rotating the adjusting nut, so that the inner diameter of the inner support ring is changed, and the tool is suitable for condensers with different sizes.
