Abstract
The utility model relates to a steam turbine high-pressure fire resistant oil box cooling device, comprising an oil pump arranged on an oil box cover board and an oil filter; the inlet end of the oil pump and the outlet end of the oil filter are respectively connected with a pipeline which is inserted into the inner part of the oil tank; the device further comprises an air cooler; the inlet end of the air cooler is connected with the outlet end of the oil pump by the pipeline, and the outlet end of the air cooler is connected with the inlet end of the oil filter by the pipeline. A traditional water-cooling device is changed into the air cooler by the utility model, the oil passes through the air cooler for reducing the oil temperature under the action of a fan, thus not only solving the problem that water enters into the oil, but also ensuring the oil quality and saving water resource.
Description
Technical field
The utility model relates to power station steam turbine, relates in particular to a kind of turbine high-pressure fire-resistant oil fuel tank cooling unit that is used for steam turbine control hydraulic oil system.
Background technique
In the prior art, what steam turbine control hydraulic oil system adopted is EH oil (being high pressure fireresistant oil), and it is very sensitive to temperature.Too high as temperature, then oil can be very fast aging.Traditional cooling means adopts the water-cooled cooler, oil is carried out heat exchange by this cooler and water, thereby temperature is reduced.Just have such problem thus, even the sealing of water-cooled cooler is bad, and water might enter in the oil, and oil is degenerated, and is therefore higher to the seal request of water-cooled cooler, thereby improved cooling cost.The water-cooled cooling method also need the most important thing is the water source in addition, and this also is a kind of greatly waste to water resources, also causes the pollution problem of industrial wastewater easily.
The model utility content
In order to overcome the deficiency that the problems referred to above exist, the utility model aims to provide a kind of turbine high-pressure fire-resistant oil fuel tank cooling unit, in order to solve the problem of oil water inlet, reaches the purpose that guarantees oil.
A kind of turbine high-pressure fire-resistant oil fuel tank cooling unit described in the utility model, comprise the oil pump and the oil purifier that are installed on the described tank cover, and the entrance point of described oil pump and the outlet end of oil purifier are connected with a pipeline that gos deep into described fuel tank internal respectively, it is characterized in that: it also comprises an air-cooler, the entrance point of this air-cooler is connected with the outlet end of described oil pump by pipeline, and the outlet end of air-cooler is connected with the entrance point of described oil purifier by pipeline.
In above-mentioned turbine high-pressure fire-resistant oil fuel tank cooling unit, comprise that also one is arranged on the unidirectional check valve between described oil pump outlet end and the air cooler air inlet end.
In above-mentioned turbine high-pressure fire-resistant oil fuel tank cooling unit, described air-cooler comprises motor and the fan that is attached thereto.
Owing to adopted above-mentioned technical solution, the utility model changes traditional water-cooled cooler into air-cooler, with oil by air-cooler, under the effect of fan with oily temperature drop under, both solved the problem of oily water inlet, guaranteed oil; By using model utility can save great amount of water resources, can also reduce pollution to a great extent simultaneously to environment.
Description of drawings
Fig. 1 is the structural representation of the utility model turbine high-pressure fire-resistant oil fuel tank cooling unit.
Embodiment
As shown in Figure 1, the utility model, i.e. turbine high-pressure fire-resistant oil fuel tank cooling unit comprises the oil pump 1 that is installed on fuel tank 10 cover plates and oil purifier 2, air-cooler 3, wherein, the outlet end 22 of the entrance point 11 of oil pump 1 and oil purifier 2 is connected with a pipeline 5 that gos deep into fuel tank 10 inside respectively; Air-cooler 3 comprises motor 6 and the fan 7 that is attached thereto, and the entrance point 31 of air-cooler 3 is connected with the outlet end 12 of oil pump 1 by pipeline 5, and the outlet end 32 of air-cooler 3 is connected with the entrance point 21 of oil purifier 2 by pipeline 5.
The utility model comprises that also one is arranged on the unidirectional check valve 4 between oil pump 1 outlet end 12 and air-cooler 3 entrance points 31.
Working principle of the present utility model promptly adopts oil pump 1 that oil is released from fuel tank 10, receives air-cooler 3 by pipeline 5, and air-cooler 3 drives fan 7 by motor 6, and oil is cooled off.Cooled oil sends back to fuel tank 10 after by filter 2 again, thereby the oily temperature drop of whole system is got off.
In sum, the utility model is not very high to the requirement of air-cooler, thereby has reduced cooling cost, utilize fan that oily temperature drop is got off, both solved the problem of oily water inlet, guaranteed oil, also save water resources greatly, and can not cause the industrial pollution problem.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
