Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam turbine technology, specifically a combined steam turbine chassis with an integrated oil station. Background Technology
[0002] A steam turbine is a rotary power machine driven by steam, and its working principle is to convert the thermal energy of steam into mechanical energy. Currently, the oil station system in steam turbine buildings is generally located on the middle floor of the building to ensure stable static pressure of the supply / return oil by utilizing the elevation difference. However, this layout requires significant space in the building, especially for large steam turbine units. Because the oil station system uses a large amount of oil, the corresponding equipment is also relatively large, requiring a large-span, high-load-bearing platform on the middle floor. However, for some buildings with limited space, such as single-story or low-ceilinged buildings, the above-mentioned middle-floor layout is not suitable for small buildings with limited space. Utility Model Content
[0003] This utility model provides a combined steam turbine chassis with an integrated oil station that has a simple and compact structure and occupies little space.
[0004] The combined turbine chassis with integrated oil station described in this utility model includes a chassis. The fuel tank is located inside the chassis; The gearbox is fixed to the rear of the chassis; The generator is fixed to one side of the gearbox; The range hood is fixed to the top of the gearbox; An oil cooler is fixed to the side of the chassis longitudinally adjacent to the gearbox; and an AC lubricating oil pump, a DC screw oil pump, an AC control oil pump, a lubricating oil double-cylinder filter, and a control oil double-cylinder filter are arranged sequentially and fixed to the chassis along the same transverse axis of the oil cooler.
[0005] The combined turbine chassis with integrated oil station integrates an oil tank inside the chassis, and also integrates all the necessary equipment for the control oil system and lubrication oil system onto the turbine chassis, forming a single-layer layout structure. This shortens the connecting pipes between components, reduces the space occupied, and lowers the overall cost.
[0006] As a preferred embodiment of this utility model, a heater for heating the oil tank is also provided on one side of the generator on the chassis, and the heating end of the heater extends into the oil tank.
[0007] As a preferred embodiment of this utility model, an oil level indicator for observing the oil level in the oil tank is also provided on one side of the chassis, and the observation surface of the oil level indicator is directly connected to the oil tank. Attached Figure Description

[0011] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0012] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "equipped with," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0014] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "several" means one or more, "multiple" means two or more, and "above," "below," and "within" are all understood to include the stated number. Furthermore, the technical features of each embodiment can be arbitrarily combined. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described; however, as long as these combinations of technical features do not contradict each other, they should be considered within the scope of this specification.
[0015] like Figure 1-3 As shown, a combined steam turbine chassis with an integrated oil station includes chassis 1. Fuel tank 2 is located inside the chassis; Gearbox 3 is fixed to the rear of chassis 1; Generator 4 is fixed to one side of the gearbox 3; The range hood 5 is fixed to the top of the gearbox 3; The oil cooler 6 is fixed to the side of the chassis 1 longitudinally adjacent to the gearbox 3; and the AC lubricating oil pump 7, DC screw oil pump 8, AC control oil pump 9, lubricating oil double cylinder filter 10 and control oil double cylinder filter 11 are arranged sequentially and fixed to the chassis 1 along the same transverse axis of the oil cooler 6.
[0016] The combined turbine chassis with integrated oil station integrates an oil tank inside the chassis, and also integrates all the necessary equipment for the control oil system and lubrication oil system onto the turbine chassis, forming a single-layer layout structure. This shortens the connecting pipes between components, reduces the space occupied, and lowers the overall cost.
[0017] It should be noted that the connections or interconnections between the oil tank 2, gearbox 3, generator 4, range hood 5, oil cooler 6, AC lubricating oil pump 7, DC screw oil pump 8, AC control oil pump 9, lubricating oil double-cylinder filter 10, and control oil double-cylinder filter 11 in the turbine system are existing public knowledge and belong to conventional technology in this field. The AC lubricating oil pump 7, DC screw oil pump 8, and AC control oil pump 9 provide oil to the oil system during different stages of turbine startup, operation, and shutdown.
[0018] Specifically, the output shaft of the gearbox is connected to the generator via a coupling, and the gearbox and generator share a lubrication station. A range hood is installed on top of the gearbox to remove fumes and gases generated within the gearbox and oil tank, creating a slight negative pressure within the oil tank.
[0019] The lubricating oil pipeline connections for different oil pumps are as follows: Main oil tank → Main oil pump → Oil cooler → Lubricating oil double cylinder filter → Bearings of gearbox, generator, steam turbine, etc. → Oil return pipe → Main oil tank; Main oil tank → AC lubricating oil pump → oil cooler → dual-cylinder lubricating oil filter → bearings of gearbox, generator, steam turbine, etc. → oil return pipe → main oil tank; Main oil tank → DC screw oil pump (as a standby / emergency pump) → dual-cylinder lubricating oil filter → bearings of gearbox, generator, turbine, etc. → return oil pipe → main oil tank; The control oil circuit is as follows: main oil tank → AC control oil pump (main pump) → control oil double cylinder filter → high pressure shut-off system, main steam valve, regulating steam valve servo mechanism, etc. → actuator return oil → main oil tank.
[0020] A heater 12 for heating the oil tank is also provided on one side of the generator on the chassis. The heating end of the heater extends into the oil tank to maintain the required temperature of the oil in the tank.
[0021] An oil level indicator 13 is also provided on one side of the chassis for observing the oil level in the oil tank. The observation surface of the oil level indicator is directly connected to the oil tank to display the oil level in real time, which is convenient for observation and improves the efficiency of inspection and the safety of turbine unit operation.
