Abstract
The utility model provides a double-oil-pressure oil pump of a steam turbine. The utility model comprises a pump body, an impeller and a pump shaft, wherein an oil suction opening and oil outlets are arranged on the pump body. The utility model is characterized in that at least two oil outlets with different output pressure are arranged on the pump body. The oil pump is a centrifugal oil pump, the back of an intermediate stage of the centrifugal oil pump is provided with a low-pressure oil outlet, and a final stage of the centrifugal oil pump is provided with a high-pressure oil outlet. At least two strands of oil with different pressure are outputted by a single oil pump, and an oil supply requirement that an oil supply system of the steam turbine has two kinds of oil pressure can be satisfied. The utility model has the advantages of simple and compact structure and energy saving.
Description
Technical field
The utility model belongs to oil pump, mainly is the oil supply system that is used for equipment such as steam turbine, is a kind of pair of oil pressure steam turbine oil pump specifically.
Background technique
In the steam turbine oil supply system, need the oil of two kinds of different pressures of high pressure (adjusting security personnel use) and low pressure (lubricated using).Have dual mode to solve this problem in traditional oil supply system: a kind of a part of high pressure oil throttling step-down of oil pump being confessed with restricting orifice is a low pressure oil; Another kind be by injector with one high pressure oil injection part apiezon oil from fuel tank, the oil that is mixed into lower pressure is used for lubricated.Directly the throttling step-down causes very big energy loss to have a strong impact on system effectiveness.Injector efficient in the another kind of solution is also very low, causes system's power consumption waste.How a kind of oil pump that improves structure is provided, makes the oil of the exportable different pressures of separate unit oil pump, and the efficient height, energy saving, this has become the problem that presses for technician's solution at present.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of pair of oil pressure steam turbine oil pump is provided, the oil of at least two strands of different pressures of separate unit oil pump output, can satisfy the fuel feeding requirement that two kinds of oil pressure are arranged in the oil supply system of steam turbine, and simple in structure, efficient height, energy saving.
The purpose of this utility model is achieved by the following technical solution: a kind of pair of oil pressure steam turbine oil pump, comprise the pump housing, impeller, pump shaft, inlet port and oil outlet are set on the pump housing, it is characterized in that being provided with at least on the described pump housing two oil outlets that delivery pressure is different.
Described oil pump is a centrifugal oil pump, and the low pressure oil outlet is set after the centrifugal oil pump intergrade.
Described oil pump is the level Four centrifugal oil pump, and the low pressure oil outlet is set after the oil pump first order, and the high pressure oil outlet is set behind the oil pump fourth stage.
The utility model compared with prior art has the following advantages and good effect:
1, the utility model is the above multistage oil pump of two-stage, only with the oil of separate unit oil pump with regard to exportable at least two strands of different pressures, according to the pressure requirement, leaves the oil of hydraulic fluid port output lower pressure after suitable level, at the oil of final stage oil outlet output elevated pressures.The separate unit oil pump can be provides high pressure (adjusting security personnel use) and low pressure (lubricated using) two kinds of different pressures oil in the steam turbine oil supply system.Its efficient height, but energy saving.
2, the utility model is simple in structure, and processing and fabricating is convenient, and cost is low, can improve the competitiveness of product in market.
Description of drawings
Fig. 1 is the sectional drawings of the two oil pressure level Four centrifugal oil pumps of the utility model along axis.
Embodiment
Referring to Fig. 1, be a kind of couple of oil pressure steam turbine oil pump embodiment of the present utility model, comprise the level Four centrifugal oil pump that the pump housing 1, impeller 2, pump shaft 3 are formed, one inlet port 6 is set on the pump housing 1, low pressure oil outlet 5 is set after the oil pump first order on the pump housing 1, high pressure oil outlet 4 is set behind the oil pump fourth stage.
During use, with the oil of the oil outlet 5 output lower pressures that are provided with after the first order on two oil pressure steam turbine oil pump pump housings 1 of one, for providing lubrication oil in the steam turbine oil supply system; The oil of final stage oil outlet 4 output elevated pressures on the pump housing 1 can be to provide in the steam turbine oil supply system and regulates security personnel with oily.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
Claims (3)
