Problems solved by technology

[0004] The disadvantages of traditional repair methods are: (1) Usually, deformation is easy to occur after filling and welding, and it is necessary to correct it first and then go to the smooth surface of the boring machine; (2) The workload of correcting the deformed compression plate due to filling and welding is large, and a lot of resources are wasted ; (3) Due to the strong corrosion of seawater, the water inlet and outlet of the compression plate corrode quickly to cause water leakage. New ones need to purchase plates, and have to process the corresponding shape and shape, which costs a lot of money; (5) material changes, air holes will be generated during filling welding, and assembly after processing requires pressure test and water leakage, and repeated disassembly and assembly waste a lot of manpower

Embodiment 1

[0033] The repair method of the fin cooler of the present embodiment may further comprise the steps:

[0034] (1) Machining the water outlet or water inlet of the compression plate 1, increasing the diameter of the inner hole to remove the corrosion part, forming an inner hole channel 3, the left and right sides of the inner hole channel 3 are symmetrical steps shape, including the first stepped passage 31, the straight passage 32 and the second stepped passage 33 which are connected with each other in turn, and the first stepped passage 31, the straight passage 32 and the second stepped passage 33 are all cylindrical, and the first stepped passage 31 and the inner diameter of the second stepped passage 33 is greater than the inner diameter of the straight passage 32, and the lengths of the first stepped passage 31 and the second stepped passage 33 are 5-6 mm;

[0035] (2) Use 316L stainless steel plate to prefabricate the sleeve 5 and the meson 4 respectively, the sleeve 5 is...

Embodiment 2

[0042] The repair method of the fin cooler of the present embodiment may further comprise the steps:

[0043] (1) Machining the water outlet or water inlet of the compression plate 1, the diameter of the inner hole is increased to form an inner hole channel 3, and the left and right sides of the inner hole channel 3 are stepped, including successively mutual Connected first stepped passage 31, straight passage 32 and second stepped passage 33, the first stepped passage 31, straight passage 32 and second stepped passage 33 are cylindrical, the first stepped passage 31 and the second stepped passage The inner diameter of 33 is greater than the inner diameter of the straight channel 32;

[0044] (2) prefabricated sleeve 5 and meson 4 respectively with stainless steel plate, sleeve 5 is used to be installed in straight tube passage 32, and meson 4 is used to be installed in first stepped passage 31 or second stepped passage 32, and meson 4 is an annular barrel;

[0045](3) Put t...

Embodiment 3

[0048] The method for repairing the sheet cooler of this embodiment, wherein step (1) also includes removing the flange on the pressing plate before machining the water outlet or water inlet of the pressing plate, and prefabricating with a stainless steel plate A new flange of the same size as the old flange is installed and fixed on the water outlet or water inlet of the compression plate, and the rest are the same as in Embodiment 1.

[0049] This embodiment is applicable to the situation where the flange on the pressure plate is severely corroded and damaged.

Abstract

The invention discloses a repair method of a chip cooler. The repair method comprises the following steps of (1) machining a water outlet or a water inlet of a pressure strip, and enlarging the diameter of an inner hole in a turning mode to remove a corroded part and to form an inner hole channel; (2) respectively prefabricating a sleeve and a meson by using a stainless steel plate; (3) respectively putting the sleeve and the meson into the inner hole channel to complete the assembly and the fixation; and (4) using a boring mill to flatten the two sides of the pressure strip. The repair methodof the chip cooler can increase the sealing property of the water outlet of the plate-cooling pressure strip, the pressure strip is not prone to sea water corrosion, and then the good operation condition of a main engine and a generator can be guaranteed and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of coolers, in particular to a method for repairing fin coolers. Background technique [0002] The operation of the main engine and generator of the heart of the ship needs to be cooled by the plate cooler to maintain continuous work. The plate cooler is their cooling system, commonly known as plate cooling. The structure of the chip cooler generally includes compression plates on both sides and multiple (hundreds) cooling plates arranged between the two compression plates. For chip coolers on ships, the size of the compression plates on both sides is usually It is H40-100×750mm×1750mm, and each compression plate has four water inlets and outlets (such as figure 1 Shown), are the inlet and outlet of the cooling liquid, the inlet and outlet of the cooled liquid, respectively. The space between every two cold plates is set as a flow channel of one of the fluids, and is spaced apart, and the cooling liquid an...
