Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary components of generator sets, in particular to a base structure of a generator set with an integrated lubrication system. Background Art

[0002] The generator set usually needs to be installed on a base. The lubricating oil tank of the generator set in the prior art mainly has two forms:

[0003] (1) The main beam of the base is mainly formed by hot-rolled channel steel or plate bending, and is connected and welded with steel plates in the middle of the left and right main beams to form a closed space to form an oil tank.

[0004] (ii) An external auxiliary oil tank is added and connected to the unit through an oil pipeline.

[0005] The main beam of the unit base is usually made of hot-rolled channel steel. The rough surface of the channel steel is easy to rust, and it is easy to produce cold welding or welding deformation during welding, which is easy to cause deviations in the subsequent engine generator installation and centering adjustment. If the main beam is formed by bending the plate, the bending strength of the plate is not high when the plane is stressed, and it is easy to bend and deform; in order to ensure that the deformation is small, the thickness of the plate must be thickened, which greatly increases the weight of the base.

[0006] The original unit base oil tank has problems:

[0007] (1) After the space between the left and right main beams is made into an oil tank, the center height of the engine and generator installed on the base must be increased accordingly, causing the center of gravity of the unit to be raised upward, increasing the risk of instability during unit operation.

[0008] (2) The steel plates used in the original design for the upper and lower sealing plates of the oil tank at the base are large in area, which is prone to produce cold welds and loose welding during the welding process. At the same time, the welding deformation is also large, which increases the risk of oil tank leakage during unit operation.

[0009] (3) The original base oil tank has a flat structure, large dimensions in length and width, and small height. In order to reduce deformation, steel plates are usually used as reinforcement ribs inside the oil tank to divide the internal space into small pieces. During the later oil change process of the oil tank, it is impossible to clean the impurities inside the oil tank, and it is even impossible to discharge all the waste oil.

[0010] In addition, the external auxiliary oil tank not only increases the space occupied by the unit, but also increases the material cost of the oil tank and oil pipeline. Utility Model Content

[0011] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a unit base structure with an integrated lubrication system, thereby greatly saving floor space, facilitating oil tank maintenance, and greatly improving overall working reliability.

[0012] The technical solution adopted by the utility model is as follows:

[0013] A unit base structure with an integrated lubrication system comprises a left main beam and a right main beam arranged in parallel at intervals, the left main beam and the right main beam are supported and connected by a plurality of spaced cross beams, the outer end surfaces of the left main beam and the right main beam at one end are welded with oil pump mounting plates at the same time, a pre-supply oil pump and a replenishing oil pump are fixed on the oil pump mounting plates, and the outer end surfaces of the left main beam and the right main beam at the other end are installed with flange covers through sealing gaskets and fasteners; an engine supporting foot and a generator fixing foot are installed on the cross beam; the left main beam and the right main beam are both hollow structures inside and are filled with oil, the left main beam serves as an auxiliary oil tank, and the right main beam serves as a new oil tank; it also comprises an engine oil pan, the upper part of the engine oil pan is connected to the inside of the auxiliary oil tank through an overflow pipe, an engine oil level sensor is installed beside the engine oil pan, the lower part of the engine oil pan is connected to the inside of the auxiliary oil tank through the pre-supply oil pump, the auxiliary oil tank and the new oil tank are simultaneously connected to the replenishing oil pump, and it also comprises an engine lubricating oil pump, which pumps oil from the engine oil pan to supply lubricating oil to the engine.

[0014] As a further improvement of the above technical solution:

[0015] The left main beam and the right main beam are both made of full-length seamless rectangular steel pipes.

[0016] Magnetic studs are installed inside the left main beam and the right main beam.

[0017] A No. 1 pre-supply oil pump valve and a No. 2 pre-supply oil pump valve are respectively installed on the pipelines at both ends of the pre-supply oil pump.

[0018] An oil level gauge for the oil replenishment tank is installed in the right main beam.

[0019] A vent is provided on the top surface of the right main beam.

[0020] A manual refueling port is provided on the top surface of the right main beam.

[0021] Lifting plates are welded to the outer sides of the left main beam and the right main beam.

[0022] Inlet and outlet oil pipe joints are provided on the top surfaces of the left main beam and the right main beam.

[0023] The beneficial effects of the utility model are as follows:

[0024] The utility model has a compact and reasonable structure and is easy to operate. By integrating the base of the unit and the lubrication system, the floor space can be greatly saved. The oil tank is also convenient for maintenance and cleaning, which greatly improves the overall working reliability.

[0025] The utility model also has the following advantages:

[0026] (1) The utility model adopts a steel base structure and integrates a lubricating oil system in the base. The overall structure is compact and the working reliability is good.

[0027] (2) The utility model adopts a seamless rectangular steel pipe, and due to the hollow structure of the steel pipe, the overall weight of the base is correspondingly reduced.

[0028] (3) The main beam is made of rectangular steel pipe. Due to the high strength of the steel pipe, there is no need for a reinforcing plate inside the steel pipe, which reduces the use of steel and reduces material costs.

[0029] (4) The integrated design of the base and the fuel tank simplifies the manufacturing of the base and the fuel tank, thus saving manufacturing labor costs.

[0030] (5) The integrated design of the base and the fuel tank makes the generator set compact, small in size and beautiful in appearance.

[0031] (6) The left and right main beams of the base oil tank are designed to be continuous from the engine head to the generator tail, which ensures the base strength and the oil tank capacity. In addition, the left and right oil tanks have different design functions. In the fuel unit, the fuel consumption time is increased, especially in unmanned power stations, which reduces the number of refueling of the unit and reduces personnel costs; in the gas unit, the lubricating oil capacity is increased, the lubricating oil consumption and deterioration time is extended, the number of lubricating oil changes is reduced, the economy is increased, and the environmental protection of the unit is increased.

DETAILED DESCRIPTION

[0037] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0038] like Figure 1-Figure 4 As shown, the unit base structure with integrated lubrication system of this embodiment includes a left main beam 1 and a right main beam 2 arranged in parallel at intervals, and the left main beam 1 and the right main beam 2 are supported and connected by a plurality of spaced cross beams 3. The outer end surfaces of the left main beam 1 and the right main beam 2 at one end are welded with an oil pump mounting plate 11 at the same time, and a pre-supply oil pump 15 and a replenishing oil pump 16 are fixed on the oil pump mounting plate 11. The outer end surfaces of the left main beam 1 and the right main beam 2 at the other end are installed with a flange cover plate 6 through a sealing gasket 14 and a fastener; an engine support foot 4 and a generator fixing foot 5 are installed on the cross beam 3; the left main beam 1 and the right main beam 2 are welded with an oil pump mounting plate 11 at the same time, and a pre-supply oil pump 15 and a replenishing oil pump 16 are fixed on the oil pump mounting plate 11; the outer end surfaces of the left main beam 1 and the right main beam 2 at the other end are installed with a flange cover plate 6 through a sealing gasket 14 and a fastener; an engine support foot 4 and a generator fixing foot 5 are installed on the cross beam 3; The interior of the main beam 2 is a hollow structure and is filled with oil. The left main beam 1 serves as an auxiliary oil tank, and the right main beam 2 serves as a new oil tank. It also includes an engine oil pan 18. The upper part of the engine oil pan 18 is connected to the interior of the auxiliary oil tank through an overflow pipe 19. An engine oil level sensor 17 is installed next to the engine oil pan 18. The lower part of the engine oil pan 18 is connected to the interior of the auxiliary oil tank through a pre-supply oil pump 15. The auxiliary oil tank and the new oil tank are connected to the replenishing pump 16 at the same time. It also includes an engine lubricating oil pump 20. The engine lubricating oil pump 20 pumps oil from the engine oil pan 18 to supply lubricating oil to the engine.

[0039] The left main beam 1 and the right main beam 2 are both made of full-length seamless rectangular steel pipes.

[0040] Magnetic studs 13 are installed inside the left main beam 1 and the right main beam 2.

[0041] A first pre-supply oil pump valve 21 and a second pre-supply oil pump valve 22 are respectively installed on pipelines at both ends of the pre-supply oil pump 15 .

[0042] An oil level gauge 8 for the oil replenishment tank is installed in the right main beam 2.

[0043] A vent 7 is provided on the top surface of the right main beam 2 .

[0044] A manual refueling port 9 is provided on the top surface of the right main beam 2 .

[0045] Lifting plates 10 are welded to the outer sides of the left main beam 1 and the right main beam 2 .

[0046] Inlet and outlet oil pipe joints 12 are provided on the top surfaces of the left main beam 1 and the right main beam 2 .

[0047] The main beam of the generator set described in the utility model adopts a full-length seamless rectangular steel pipe. The middle and both ends of the left main beam 1 and the right main beam 2 are appropriately connected by a cross beam 3. An oil pump mounting plate 11 is designed at the front end of the base for installing the oil pump, so that the main beam oil tank can be connected to the left and right through the oil pump and pipelines.

[0048] A lifting plate 10 is welded on the outside of the steel pipe to facilitate transportation, installation and disassembly.

[0049] The mounting support legs of the engine and generator are welded to the main beam steel pipe and supported by the corresponding cross beam 3, which increases the supporting strength of the heavy components such as the engine and generator.

[0050] The main beam, the cross beam 3, the oil pump mounting plate 11, the lifting plate 10, and the mounting support feet are welded to form a whole, which ensures the strength and rigidity of the base and meets the requirements for transportation and movement after the unit is installed on the base.

[0051] Because the steel pipe surface is smooth and flat, with high bending strength and small flexural deformation, the deformation is small during welding, so that each installation and fixing position of the base can ensure the welding flatness, reducing the subsequent installation error of the unit. At the same time, the lowest part of the engine can sink into the space between the left main beam 1 and the right main beam 2, which correspondingly lowers the center of gravity of the engine.

[0052] The left main beam 1 and the right main beam 2 also serve as an extended oil tank. The inlet and outlet oil pipe joints 12, the oil level gauge installation port, and the oil tank vent installation port are welded on the upper part of the rectangular steel pipe, so that the rectangular steel pipe becomes a complete oil tank body. At the same time, the seamless steel pipe has fewer welds, which reduces the risk of leakage.

[0053] The interior of the steel pipe is a straight long space, with a welded seal at one end and a seal 14 plus a flange cover 6 at the other end. When the lubricating oil is replaced later, the flange cover 6 can be opened to thoroughly clean the sediment and waste oil inside the oil tank. At the same time, a magnetic stud 13 is designed inside the steel pipe. The metal scraps generated during the operation of the machine are brought into the oil tank through the oil circulation and are absorbed by the magnetic stud 13 to avoid entering the engine again and wearing out the engine parts.

[0054] The base oil tank directly adopts the left main beam 1 and the right main beam 2, and is designed to be full-length from the engine head to the generator tail, which ensures the strength of the base main beam and also makes the unit base oil tank have a larger capacity to meet the long-term operation requirements of the unit.

[0055] The functions of the oil tanks designed for the left main beam 1 and the right main beam 2 are different. The oil tank of the left main beam 1 is designed as an auxiliary oil tank, which can be used for daily fuel consumption during the operation of the fuel generator set, or for the gas generator set to communicate the lubricating oil in the engine oil pan 18 through the pre-supply oil pump 15, which expands the lubricating oil capacity and extends the lubricating oil replacement cycle. The right oil tank of the right main beam 2 is a new oil tank. The purpose is to send a signal through the engine oil level sensor 17 after the oil level in the auxiliary oil tank and the engine oil pan 18 drops to a certain level, start the oil replenishment pump 16 to extract the oil in the new oil tank and automatically add it to the auxiliary oil tank, thereby increasing the running time of the generator set.

[0056] The lubricating oil in the engine oil pan 18 and the lubricating oil in the auxiliary oil tank (ie, the left main beam 1) constitute an overall lubricating oil reserve for engine lubrication.

[0057] The engine oil pump 20 pumps oil from the engine oil pan 18 to supply lubricating oil to the engine.

[0058] A lubricating oil cooler is installed in the oil supply system pipeline, and the cooled lubricating oil will enter the engine through the lubricating oil filter. The pre-supply oil pump 15 returns a small part of the cooled lubricating oil to the auxiliary oil tank (i.e., the left main beam 1). The auxiliary oil tank (i.e., the left main beam 1) is always filled with lubricating oil. Through the overflow pipe 19, the lubricating oil flows back to the engine oil pan 18 without pressure, so that all the lubricating oil circulates once or twice per hour. When the engine is started at low temperature, after about three to four hours of operation, the lubricating oil will be evenly heated, effectively lubricating and protecting the engine.

[0059] The system monitors the engine oil pan 18 through the engine oil level sensor 17, and the supplementary oil tank oil level gauge 8 monitors the oil level of the supplementary oil tank (i.e., the right main beam 2). Once the oil level in the engine oil pan 18 drops, the supplementary oil pump 16 will pump fresh lubricating oil from the supplementary oil tank (i.e., the right main beam 2) and supply it to the auxiliary oil tank (i.e., the left main beam 1).

[0060] When the unit is undergoing maintenance and needs to replace the lubricating oil in the engine oil pan 18 and the auxiliary oil tank (i.e., the left main beam 1), adjust the opening and closing directions of the No. 1 pre-supply oil pump valve 21 and the No. 2 pre-supply oil pump valve 22, start the pre-supply oil pump 15 as an oil pump, and drain the waste oil in the engine oil pan 18 and the auxiliary oil tank (i.e., the left main beam 1); then open the flange cover plate 6 at the end of the auxiliary oil tank (i.e., the left main beam 1), clean the sediment inside the oil tank and the metal scraps adsorbed around the magnetic screws, and check the integrity of the sealing gasket 14. If the replenishing oil tank (i.e., the right main beam 2) needs to be cleaned after long-term use, the above steps are also followed. After the cleaning and maintenance is completed, restore the various components of the oil supply system, start the replenishing oil pump 16 again, replenish the lubricating oil into the auxiliary oil tank (i.e., the left main beam 1), and replenish it into the engine oil pan 18 through the overflow pipe 19. The overall operation is convenient, the structure is compact, and the working reliability is good.

[0061] The utility model adopts steel pipes, which have high bending strength, so the overall stress deformation of the unit base is relatively small. At the same time, because the surface of the steel pipe is smooth and flat, the welding deformation is small, which ensures the subsequent installation error of the unit.

[0062] The main beam of the generator set is designed as a fuel tank using seamless rectangular steel pipes. The welded parts of the seamless steel pipes are greatly reduced, reducing the risk of leakage. The main beam uses seamless rectangular steel pipes to release the space between the left main beam 1 and the right main beam 2, which reduces the installation height of the unit and thus reduces the center of gravity of the unit. Since the rectangular steel pipe has a suitable height, it is convenient for subsequent cleaning of the inside of the fuel tank.

[0063] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
