Description

Technical Field

[0001] The utility model belongs to the technical field of the fuel supply filtering system of diesel generator sets, and particularly relates to a maintenance-free oil filter maintenance system and a generator set. Background Art

[0002] Diesel generator sets are widely used in life. Especially some high-power generator sets can be used as backup power sources to ensure continuous power supply when the mains power is interrupted. The generator set filters harmful impurities and moisture in the fuel system through a filter to reduce wear and avoid blockage, so as to protect the normal operation of the engine.

[0003] For high-power generator sets, the fuel consumption can reach 500 - 600 L per hour. A large amount of diesel is easily blocked after passing through the diesel filter, especially when the generator set is not started for a long time or the oil quality is relatively poor, it is more likely to cause blockage.

[0004] Therefore, in order to solve the technical problem that in some important power consumption places such as hospitals and data centers, if the generator set stops for maintenance, it will lead to accidents or data loss, it is urgent to design a maintenance-free oil filter maintenance system for the generator set.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, it is not considered that the above description constitutes the information of the prior art. Summary of the Utility Model

[0016] A lower oil outlet branch pipe, which is connected in through - connection with the oil outlet ports of the first filter assembly and the second filter assembly.

[0017] In an alternative embodiment, the lower oil inlet branch pipe and the lower oil outlet branch pipe are respectively composed of a plurality of connecting pipes, and the connecting pipes are thread - adapted to each other and connected in series through screws.

[0018] In an alternative embodiment, the valve is a mechanical valve, and a synchronous connecting rod is arranged between the two mechanical valves. Both ends of the synchronous connecting rod are connected to the adjusting handles of the mechanical valves.

[0019] In an alternative embodiment, the valve is an electric control valve, and the two electric control valves are synchronously controlled by a control module.

[0020] In a second aspect, an embodiment of the present disclosure provides a generator set, including the above - mentioned oil filter maintenance system without shutdown.

[0037] It has been found through research that the disadvantages of the prior art are as follows: for a high-power generator set, the fuel consumption can reach 500 - 600 L per hour.

[0041] The following will describe in detail some embodiments of the present utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0042] Referring to Figure 1 , an embodiment of the present disclosure provides a maintenance-free oil filter maintenance system, including: a filter assembly, which includes a first filter assembly 1 and a second filter assembly 2; the first filter assembly 1 and the second filter assembly 2 are adapted to filter impurities and moisture in the engine oil to protect the normal operation of the engine. A pipeline assembly 3, including corresponding pipelines that are connected through to the first filter assembly 1 and the second filter assembly 2, and is provided with an oil inlet 21 and an oil outlet 22; the unfiltered oil is introduced into the filter assembly through the oil inlet 21, and after being filtered by the filter assembly, it is led out from the oil outlet 22. A valve 4, which is arranged on the corresponding pipeline and is adapted to synchronously switch the engine oil pipelines of the first filter assembly 1 and the second filter assembly 2, so that the corresponding filter assembly is communicated with the oil inlet 21 and the oil outlet 22.

[0043] Continuing to refer to Figure 1 , the valve 4 is adapted to adjust the opening and closing direction of the pipeline assembly 3, so that the unfiltered oil flows into the first filter assembly 1 or the second filter assembly 2 through the pipeline assembly 3; by providing the first filter assembly 1 and the second filter assembly 2, when one of the first filter assembly 1 or the second filter assembly 2 is working, the other remains in a standby state. When one of the filter assemblies becomes blocked or needs maintenance, the opening and closing direction of the pipeline assembly 3 can be quickly switched through the valve 4, so that the engine oil flows into the engine oil pipeline of the other standby first filter assembly 1 or second filter assembly 2, and it can be quickly started and put into work. At the same time, the blocked filter assembly stops working, which is convenient for its maintenance, so as to realize the maintenance and repair of the filter assembly of the diesel generator set without stopping the diesel generator.

[0044] Compared with some existing technologies, the filtering oil circuit of the diesel generator set is relatively complex, and the number of control valves is large, and the operation is cumbersome. When a filter assembly fails, the work of the two filter assemblies cannot be quickly switched. Through the setting of the valve 4 in this embodiment, the first filter assembly 1 or the second filter assembly 2 can be quickly and efficiently switched to work, improving the work efficiency.

[0045] In an alternative embodiment, referring to Figure 1, the pipeline assembly 3 is symmetrically arranged between the first filter assembly 1 and the second filter assembly 2. The pipeline assembly 3 includes: an upper oil inlet branch pipe 31; it is communicated with the oil delivery pipe of the engine oil, and the engine oil is adapted to flow into the first filter assembly 1 or the second filter assembly 2 through the upper oil inlet branch pipe 31. A lower oil inlet branch pipe 33, the two lower oil inlet branch pipes 33 are respectively arranged at both ends of the valve 4, and the two lower oil inlet branch pipes 33 are respectively connected through holes to the oil inlet 21 of the first filter assembly 1 and the second filter assembly 2. The engine oil flows through the valve 4 via the upper oil inlet branch pipe 31, and the valve 4 is adapted to adjust the opening and closing direction of the pipeline assembly 3 so that the engine oil flows to the first filter assembly 1 or the second filter assembly 2 through the lower oil inlet branch pipe 33 and the oil inlet 21 in sequence.

[0046] Please continue to refer to Figure 1 , an upper oil outlet branch pipe 32; it is communicated with the oil output pipe of the engine oil, and the output pipe is adapted to deliver the engine oil to the engine, a lower oil outlet branch pipe 34, the two lower oil outlet branch pipes 34 are respectively arranged at both ends of the valve 4, and the two lower oil outlet branch pipes 34 are respectively connected through holes to the oil outlet 22 of the first filter assembly 1 or the second filter assembly 2. The valve 4 is adapted to adjust the opening and closing direction of the pipeline assembly 3 so that the filtered oil is delivered to the engine through the upper oil outlet branch pipe 32.

[0047] In an alternative embodiment, the lower oil inlet branch pipe 33 and the lower oil outlet branch pipe 34 are respectively composed of a plurality of connecting pipes. Preferably, the number of the connecting pipes is not less than four. The connecting pipes are threadedly adapted to each other and are connected in series through screws. The lower oil inlet branch pipe 33 and the lower oil outlet branch pipe 34 adopt a multi-section pipe connection method, which is convenient for installation and disassembly. If one of the interfaces is locked, the filter assembly can be disassembled through other interfaces, which is convenient for the maintenance and repair of the filter assembly.

[0048] In an alternative embodiment, the valve 4 is a mechanical valve. Preferably, the mechanical valve is a three-way valve. The valve 4 is adapted to guide the engine oil to flow into the first filter assembly 1 or the second filter assembly 2 through the upper oil inlet branch pipe 31 and to flow to the engine through the upper oil outlet branch pipe 32. A synchronous connecting rod 5 is arranged between the two mechanical valves, and both ends of the synchronous connecting rod 5 are connected to the adjusting handles of the mechanical valves. By arranging the synchronous connecting rod 5, the valve 4 can be adjusted quickly and synchronously.

[0049] If the first filter assembly 1 is blocked during operation, by pushing the synchronous connecting rod 5, the valve 4 can be adjusted quickly and synchronously so that the first filter assembly 1 is closed with the oil inlet 21, the oil outlet 22 and the pipeline assembly 3; at the same time, the second filter assembly 2 is conducted with the oil inlet 21, the oil outlet 22 and the pipeline assembly 3. At this time, the second filter assembly 2 is turned on to enter the working state, and the first filter assembly 1 is in a standby working state, which is convenient for its disassembly and maintenance.

[0050] In an alternative embodiment, please refer to Figure 2 , the valve 4 is an electrically controlled valve, and the two electrically controlled valves are synchronously controlled by a control module. The control module can be, but is not limited to, a PLC module.

[0051] An alternative embodiment provides a generator set, including the oil filter maintenance system without shutdown used in the above embodiments.

[0052] In some embodiments, the generator set can be a diesel generator.

[0053] In the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0054] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, terms such as "first", "second" and other numerical terms used herein do not imply an order or sequence unless clearly indicated in the text. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer or section discussed above can be referred to as the second element, component, region, layer or section.

[0055] Spatially relative terms, such as "inner", "outer", "below", "beneath", "lower", "above", "upper", etc., may be used herein for ease of description to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientation depicted in the figures, spatially relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is turned over, an element described as "below" or "beneath" another element or feature will be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both an above and below orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein are to be interpreted accordingly.

[0056] Inspired by the above-described ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
