Abstract
The utility model discloses a hydroelectric set upper guide bearing cooler, it comprises the semi -circular cooler of two relative settings, two semi -circular coolers enclose and circularize the structure, every semi -circular cooler all is provided with the condenser tube that the multilayer was arranged from top to bottom, every layer of condenser tube coiled is double -deck semi -circular, and every layer of condenser tube's delivery port and water inlet all lie in same one side, again through outside inlet tube and the drain pipe of flange joint after the delivery port of two semi -circular coolers and water inlet collect respectively. The utility model discloses a two independent cooling unit have reduced the volume of single equipment, and it is on -the -spot conveniently to bring equipment fixing into to easily overhaul and equipment replacement installation work at the scene.
Description
Technical field
This utility model relates to technical field of hydroelectric generation, specifically a kind of turbine-generator units top guide bearing cooler.
Background technology
In hydroelectric generation production activity, turbine-generator units is the equipment that water can be converted to electric energy, it it is the key equipment of power generation, its top guide bearing mainly undertakes adjustment unit centre axis, throw when constraint unit rotates is in critical field, and due to the big axle of unit, when rotating, friction generates heat with bearing shell, if being taken away by heat not in time, after temperature is increased to certain value, will cause that bearing shell burns out. Therefore bearing is immersed in the turbine oil in oil groove, by cooling down oil, bearing shell is lowered the temperature, cooler is installed in oil groove simultaneously, adopt and use water as medium and carry out heat exchange with oil, so that it is guaranteed that the temperature of bearing bush is run in safety range. Cooler owing to adopting at present is integral type loop configuration, must be enclosed within advance on big axle when unit big axle segmentation is installed and put into oil groove, after units' installation completes, cooler cannot be dismantled and take out, cooler can be hung out to change after cooler is accomplished by all removing electromotor top guide bearing and big axle upper end equipment, very big workload will be produced, add the degree of difficulty of general overhaul, therefore, current cooler is not easy to maintenance and changes.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of turbine-generator units top guide bearing cooler, demolition and assembling is carried out at the scene to facilitate, directly can dismount in upper oil guide groove, reduce the human and material resources of equipment replacement and repair and maintenance Job engagement, shorten maintenance duration.
This utility model such as techniques below scheme solves above-mentioned technical problem:
This utility model turbine-generator units top guide bearing cooler, it is made up of two semicircle coolers being oppositely arranged, two semicircle coolers surround loop configuration, each semicircle cooler is provided with the cooling water pipe that multilamellar is arranged up and down, every layer of cooling water pipe is coiled into double-deck semicircle, and the outlet of every layer and water inlet are respectively positioned on the same side, the outlet of two semicircle coolers and water inlet collect respectively after then through the water inlet pipe outside Flange joint and drain pipe.
Every layer of cooling water pipe all nestings of said two semicircle cooler are provided with steel fin.
Described each semicircle cooler is respectively provided with four layers of cooling water pipe; The cooling water pipe of each semicircle cooler forms a fixed connection each through steel components.
This utility model, by adopting split-type structure, makes cooler be divided into two independent cooling units, reduces the volume of individual equipment, therefore, it is convenient to be brought into equipment erecting bed, and be prone to site examining and repairing and equipment replacement installment work.
Accompanying drawing explanation
Fig. 1 is the perspective view of this utility model cooler.
Fig. 2 is the schematic top plan view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, this utility model cooler adopts ring-like splitted structure, it is divided into two lobes by cooler, the cooler of loop configuration is surrounded by two independent semicircle coolers, each semicircle cooler is provided with four layers of cooling water pipe from top to bottom arranged 1, four layers of cooling water pipe 1 are formed a fixed connection by steel components 3, every layer of cooling water pipe 1 is coiled into double-deck semicircle, and the outlet 5 of every layer of cooling water pipe and water inlet 6 are respectively positioned on the same side, the outlet 5 of each semicircle cooler and water inlet 6 are collected by water outlet manifold trunk 8 and water inlet manifold trunk 7 respectively, the water outlet manifold trunk 8 of two semicircle coolers and water inlet manifold trunk 7 connect water inlet pipe and the drain pipe of outside more respectively through flange 4 after collecting respectively.
Cooling water pipe 1 described in the utility model adopts copper pipe bending to be made, and equal nesting is provided with steel fin 2 on every layer of cooling water pipe, to increase cooler and outside contact area.
During work, water enters from water inlet, discharges from outlet again, cooler peripheral temperature taken away, it is achieved the purpose of radiating and cooling simultaneously after flowing through cooler.
By adopting this utility model turbine-generator units top guide bearing cooler, in the situation not removing unit other parts, directly can carry out assembly and disassembly in bearing oil groove, significantly facilitate daily repair and maintenance work, save the input of human and material resources, shorten maintenance duration.
