Description

Technical Field

[0001] This utility model relates to the field of hydro-generator technology, and in particular to the mechanical structure of the thrust oil tank control oil circuit of a vertical hydro-generator drawer cooler. Background Technology

[0002] In the field of hydro-generators, drawer-type coolers are commonly used for thrust oil tank coolers. However, this design presents a problem: because drawer-type coolers require sufficient space for disassembly and assembly, they can only be designed with a near-cubic shape. Since thrust oil tanks are typically circular, this results in significant blind spots between the drawer-type coolers, causing short circuits in the thrust oil tank's oil circuit. Therefore, the mechanical structure of the thrust oil tank control circuit in the drawer-type cooler of a vertical hydro-generator is particularly important. Utility Model Content

[0003] The purpose of this utility model is to overcome the fact that thrust oil tanks are generally circular, resulting in a large amount of space between drawer-type coolers that is a blind spot for the cooler, and the oil circuit of the thrust oil tank is short-circuited in this area. This utility model provides a mechanical structure for controlling the oil circuit of the thrust oil tank in a vertical hydro generator drawer cooler.

[0004] To achieve the above objectives, this utility model provides a mechanical structure for the thrust oil tank control oil circuit of a vertical hydro-generator drawer cooler using the following technical solution: tangential angle steel, radial angle steel, oil separator plate, nut, and bolt. The tangential angle steel is welded to the oil tank wall, and the radial angle steel is welded to the vertical rib. The tangential angle steel has one through hole, and the radial angle steel has two through holes. The oil separator plate is secured to the plane formed by the tangential angle steel and the radial angle steel using nuts and bolts.

[0005] Furthermore, the external dimensions of the oil separator are adjusted according to the external dimensions of the drawer cooler.

[0006] Furthermore, the fixed position of the oil separator is adjusted according to the center line position of the drawer cooler.

[0007] The beneficial effects of this utility model are as follows: This utility model can be adjusted according to the specific size of the thrust oil cooler of the unit through this structure. By adjusting the size and position of the oil baffle, the cooling capacity of the oil cooler can be fully utilized, which can effectively reduce the temperature of the thrust bearing. Especially for hydro-generator units that have already generated electricity, when the problem of high thrust bearing temperature occurs, the problem can be dealt with quickly, requiring only a small amount of welding inside the oil tank.

[0008] Specifically: 1. In this utility model, the tangential angle steel and radial angle steel are fixed to the thrust oil groove and the vertical rib by welding, without the need to make additional holes in the thrust oil groove for fixing; 2. The specific external dimensions of the oil separator in this utility model can be adjusted according to the external dimensions of the drawer cooler, and it can be applied to most units that use drawer-type thrust coolers, without being limited by the external dimensions of the cooler; 3. This utility model is applicable to solving the problem of redesigning the oil tank and oil circuit when the thrust bearing temperature of an already operating unit is high, so as to facilitate a quick and effective reduction of the thrust bearing temperature; 4. This utility model has a simple structure and principle, low processing cost, and is easy to install, inspect and maintain. Attached Figure Description
