Description

Technical Field

[0001] The present invention relates to the technical field of diesel generator set oil replenishment systems, and in particular to an online lubricating oil replenishment system for a diesel generator set and an operating method thereof. Background Art

[0002] As one of the core systems for the normal operation of a diesel engine, the lubricating oil system can reduce friction between components, cool components, clean impurities, prevent corrosion and seal, etc.

[0003] The lubricating oil process can be roughly summarized as follows: the lubricating oil pipeline inlet is submerged below the lubricating oil level in the fuel tank, pressurized by the oil pump, filtered through the filter, cooled in the cooler, and then enters the various lubrication points of the diesel engine, such as the crankshaft bearings, pistons, and camshafts. Finally, the lubricating oil is returned to the lubricating oil tank or return tank by gravity or a return pump, forming a closed circulation system. Although it is a closed circulation system, there is some loss of lubricating oil during the circulation of various components and pipelines. For example, the high-voltage diesel generator set MTU20V4000G23F has a rated power of 2200kW and a fuel consumption rate of 192g / kWh under rated operating conditions. After 100 hours of operation, the lubricating oil consumption is approximately 0.3% of the fuel consumption per hour, with a maximum of no more than 1% of the fuel consumption per hour. The lubricating oil consumption under rated operating conditions is 1.2672kg / h, with a maximum of no more than 4.224kg / h. Therefore, the lubricating oil consumption of diesel generator sets for long periods of continuous operation is relatively high.

[0004] In existing technology, most lubricating oil tanks are not installed separately, but are integrated into the common chassis of the diesel generator set, commonly known as the oil pan. Due to limited space, the oil pan volume cannot be designed to be large. If the diesel generator set continues to run, the lubricating oil will inevitably decrease, requiring shutdown and refueling, which will affect the continuous operation of the diesel generator set. In some special scenarios where uninterrupted emergency power supply is required, such shutdowns and power outages are absolutely unacceptable. Therefore, the development of an online oil refueling device is particularly important.

[0005] In addition, since the diesel generator set is in operation, the lubricating oil circulates in the components and oil pipelines. Therefore, the liquid level of the lubricating oil in the oil pan will fluctuate, which makes it difficult to accurately measure the lubricating oil level. Summary of the Invention

[0006] In response to the application gaps in the above-mentioned existing production technologies, the applicant provides an online lubricating oil replenishing system and operating method for a diesel generator set, which includes a set of customized oil pan lubricating oil level keepers, lubricating oil replenishing tanks and related valves and pipe fittings. The liquid level keepers control the on and off of the ball valve between the lubricating oil replenishing tank and the liquid level keepers, thereby achieving the purpose of automatic oil replenishment and shutdown, effectively avoiding the diesel generator set shutdown caused by insufficient lubricating oil, and laying the foundation for long-term continuous operation of the diesel generator set.

[0007] The technical solutions adopted in the present invention are as follows:

[0008] A diesel generator set lubricating oil online replenishing system includes an oil pan, a liquid level keeper, and a lubricating oil replenishing tank that are spaced apart. The oil pan and the liquid level keeper are connected via a No. 1 pipeline, on which a No. 1 ball valve is installed. The liquid level keeper and the lubricating oil replenishing tank are connected via a No. 2 pipeline, on which a No. 2 ball valve is installed.

[0009] The structure of the liquid level retainer is as follows: it includes a connecting oil tank connected to the No. 1 pipeline, a liquid level gauge is installed on the top surface of the connecting oil tank, a float body is arranged inside the connecting oil tank, the float body is connected to the float valve through a support rod, and the float valve is connected to the No. 2 pipeline.

[0010] Its further technical solution is:

[0011] The installation height of the lubricating oil replenishing tank is higher than the installation height of the oil pan and the liquid level retainer.

[0012] An oil dipstick is arranged inside the oil pan, and a No. 1 cock is arranged on the oil pan on the top surface of the oil dipstick.

[0013] A No. 2 cock is provided on one side of the oil pan.

[0014] A No. 3 cock is provided on the top surface of the lubricating oil replenishing tank.

[0015] A magnetic flap level gauge is installed on the lubricating oil replenishing tank.

[0016] A pipe cap is installed at the bottom of the lubricating oil replenishing tank.

[0017] The installation structure of the float valve is as follows: it includes a transversely arranged valve seat, the left end of the valve seat is installed with a valve body through a rubber ring, at the same time, the valve seat extends into the valve body, and the valve core is installed through a sealing gasket, a groove is provided below the valve core, a rocker is installed in the groove, a support is extended downward from the bottom of the valve body, the middle part of the rocker is hinged to the middle part of the rocker through a pin shaft below the support, one end of the rocker is fixed to a support rod through a nut, and the head of the support rod is locked with the float body.

[0018] The rocker has a bent structure.

[0019] An operating method for an online lubricating oil replenishing system for a diesel generator set includes the following operating procedures:

[0020] Preparation:

[0021] Before the diesel generator set is put into operation, the lubricating oil tank, liquid level keeper and oil pan should be installed and debugged first;

[0022] Oil filling work:

[0023] Inject an appropriate amount of lubricating oil into the oil pan and lubricating oil filling tank;

[0024] Start work:

[0025] Open the No. 1 ball valve and the No. 2 ball valve, and the liquid level in the connecting oil tank and the oil pan will be the same. At this time, the float body will float above the liquid level, and the float valve will be in the closed state.

[0026] Run the job:

[0027] When the diesel generator set is running, as the continuous running time increases, part of the lubricating oil will be consumed, and the liquid level in the oil pan and the connecting oil tank will drop. At this time, the float body will drop along with the liquid level in the connecting oil tank, and the support rod will also drop, gradually opening the float valve;

[0028] Oil filling work:

[0029] The lubricating oil in the lubricating oil replenishing tank flows into the connecting oil tank due to gravity. The liquid level in the connecting oil tank and the liquid level in the oil pan will rise synchronously. When the liquid level in the connecting oil tank rises, the float body rises, driving the support rod to move and gradually close the float valve until the liquid level in the connecting oil tank and the liquid level in the oil pan reach the appropriate position, and the float valve is completely closed.

[0030] Oil filling completed;

[0031] The entire system automatically cycles as described above until the diesel generator set stops running.

[0032] The beneficial effects of the present invention are as follows:

[0033] The present invention has a compact and reasonable structure and is easy to operate. Through the mutual cooperation between the oil pan, the liquid level retainer and the lubricating oil filling tank, online oil filling can be conveniently completed. The liquid level retainer controls the on and off of the ball valve between the lubricating oil filling tank and the liquid level retainer, thereby achieving the purpose of automatic oil filling and shutting down, effectively avoiding the shutdown of the diesel generator set due to insufficient lubricating oil, and laying the foundation for long-term continuous operation of the diesel generator set.

[0034] At the same time, the present invention also has the following advantages:

[0035] 1. The lubricating oil online replenishing device can monitor the lubricating oil level in the oil pan in real time to ensure that the lubricating oil level is relatively stable, thereby ensuring that the diesel generator set can continue to operate efficiently and stably.

[0036] 2. The height of the float valve in the liquid level keeper is related to the designed liquid level height of the oil pan. Different types of diesel engines have different amounts of lubricating oil. You only need to adjust the height of the float valve of the liquid level keeper. It is suitable for various types of diesel engines and has strong applicability.

[0037] 3. The liquid level keeper in the online oil replenishment device is connected or disconnected to the lubricating oil replenishment tank through a liquid level float valve. The mechanical linkage structure is simple, mature and reliable, which can ensure the high reliability of the liquid level keeper, thereby ensuring the reliability and stability of the entire online oil replenishment device.

[0038] 4. When the diesel engine is running, the oil level in the oil pan will fluctuate. If the oil is added directly to the oil pan, accidents such as oil leakage and oil contamination may occur. The online oil filling device ensures the stability of the lubricating oil level in the oil pan by adding oil to the liquid level retainer. It indirectly measures the oil level in the oil pan and adds oil, which has better safety.

[0039] 5. The liquid level height of the liquid level retainer is automatically controlled by the float valve. The buoyancy generated by the float in the lubricating oil links the support rod to move. The support rod drives the valve body to change through the rocker, realizing the opening and closing of the float valve and automatically realizing the oil replenishment operation.

[0050] The installation height of the lubricating oil replenishing tank 13 is higher than the installation height of the oil pan 1 and the liquid level retainer 7 .

[0051] An oil dipstick 3 is arranged inside the oil pan 1 , and a No. 1 cock 2 is arranged on the top surface of the oil dipstick 3 on the oil pan 1 .

[0055] A pipe cap 17 is installed at the bottom of the lubricating oil replenishing tank 13 .

[0056] The installation structure of the float valve 10 is as follows: it includes a transversely arranged valve seat 1008, and the valve body 1007 is installed on the left end of the valve seat 1008 through a rubber ring. At the same time, the valve seat 1008 extends into the valve body 1007, and the valve core 1005 is installed through a sealing gasket 1006. A groove is provided below the valve core 1005, and a rocker 1003 is installed in the groove. A support 1009 extends downward from the bottom of the valve body 1007, and the middle part of the rocker 1003 is hinged to the middle part of the rocker 1003 by a pin shaft 1004 below the support 1009. One end of the rocker 1003 is fixed to the support rod 1001 by a nut 1002, and the head of the support rod 1001 is locked with the float body 9.

[0057] The rocker 1003 has a bent structure.

[0058] The operating method of the diesel generator set lubricating oil online replenishment system of this embodiment includes the following operating procedures:

[0059] Preparation:

[0060] Before the diesel generator set is put into operation, the lubricating oil filling tank 13, the liquid level retainer 7 and the oil pan 1 are first installed and debugged;

[0061] Oil filling work:

[0062] Inject an appropriate amount of lubricating oil into the oil pan 1 and the lubricating oil replenishing tank 13;

[0063] Start work:

[0064] Open the No. 1 ball valve 5 and the No. 2 ball valve 15, and the liquid levels in the connecting oil tank 11 and the oil pan 1 are the same. At this time, the float body 9 floats above the liquid level, and the float valve 10 is in the closed state;

[0065] Run the job:

[0066] When the diesel generator set is running, as the continuous running time increases, the lubricating oil will be consumed, and the liquid level in the oil pan 1 and the connecting oil tank 11 will drop. At this time, the float body 9 will drop along with the liquid level in the connecting oil tank 11, and the support rod 1001 will also drop, gradually opening the float valve 10;

[0067] Oil filling work:

[0068] The lubricating oil in the lubricating oil replenishing tank 13 flows into the connecting oil tank 11 due to gravity. The liquid level in the connecting oil tank 11 and the liquid level in the oil pan 1 rise synchronously. When the liquid level in the connecting oil tank 11 rises, the float body 9 rises, driving the support rod 1001 to move and gradually close the float valve 10 until the liquid levels in the connecting oil tank 11 and the oil pan 1 reach appropriate positions, and the float valve 10 is completely closed.

[0069] Oil filling completed;

[0070] The entire system automatically cycles as described above until the diesel generator set stops running.

[0071] The specific structure and functions of the online lubricating oil replenishment system for a diesel generator set described in the present invention are as follows:

[0072] It mainly includes an oil pan 1, a liquid level keeper 7, a lubricating oil replenishing tank 13, a ball valve and related pipe fittings.

[0073] The liquid level retainer 7 mainly comprises a float valve 10, a float body 9 and a mechanical structure, a liquid level gauge 8, a connecting oil tank 11 and related accessories.

[0074] The lubricating oil online replenishing device is connected to the oil pan 1 through components such as hoses and valves. Figure 1 The lubricating oil replenishing tank 13 needs to be arranged at a high position. If it is arranged at a low position, it is necessary to add relevant facilities such as a replenishing oil pump.

[0075] Open the second cock 4 on the oil pan 1 to add lubricating oil into the oil pan 1;

[0076] Open the No. 1 cock 2 on the oil pan 1 and measure the level of the lubricating oil in the oil pan 1 through the oil dipstick 3;

[0077] The No. 1 ball valve 5 and the No. 1 pipeline 6 are used to connect the oil pan 1 and the liquid level keeper 7, and keep the No. 1 ball valve 5 in a normally open state during operation;

[0078] The second ball valve 15 and the second pipeline 12 are used to connect the oil tank 11 and the lubricating oil supply tank 13. The second ball valve 15 is kept in a normally open state during operation;

[0079] The liquid level meter 8 is used to monitor the liquid level in the connecting oil tank 11 in real time. The liquid level of the connecting oil tank 11 can be displayed in the user-side monitoring system. At the same time, an alarm function is set. When the liquid level in the connecting oil tank 11 reaches the high or low threshold, the monitoring system issues an alarm prompt.

[0080] The magnetic flap level gauge 16 monitors the level in the lubricant supply tank 13. When the level reaches a low threshold, refilling is necessary. Opening the third cock 14 to refill the lubricant supply tank 13 allows the magnetic flap level gauge 16 to monitor the level and refill to the desired level.

[0081] The lubricating oil in the lubricating oil replenishing tank 13 can be emptied by opening the pipe cap 17 .

[0082] According to the communicating vessel principle, the liquid levels of the oil pan 1 and the communicating oil tank 11 are the same. When the liquid level of the lubricating oil in the oil pan 1 drops, the liquid level of the lubricating oil in the communicating oil tank 11 also drops. The float and the mechanical structure floating on the liquid surface of the lubricating oil will link the float valve 10 to gradually open the float valve 10. Due to the action of gravity, the lubricating oil in the lubricating oil replenishing tank 13 will flow into the oil pan 1 through the communicating oil tank 11. As the lubricating oil in the lubricating oil replenishing tank 13 rises, the float and the mechanical structure will link the float valve 10 to gradually close the float valve 10, thereby maintaining the lubricating oil in the lubricating oil replenishing tank 13 at an appropriate liquid level.

[0083] like Figure 1 As shown, the workflow of this embodiment includes the following processes:

[0084] Before the diesel generator set is operated, first install and debug the lubricating oil filling tank 13, the liquid level retainer 7, the oil pan 1 and the related components, then inject an appropriate amount of lubricating oil into the oil pan 1 and the lubricating oil filling tank 13, open the No. 1 ball valve 5 and the No. 2 ball valve 15, then the liquid level heights in the connecting oil tank 11 and the oil pan 1 are the same, at this time the float body 9 and its mechanical structure float above the liquid level, and the float valve 10 is in the closed state; when the diesel set is running, as the continuous running time increases, part of the lubricating oil will be consumed, and the liquid level in the oil pan 1 and the connecting oil tank 11 will drop. At this time, the float body 9 and its support rod 1001 and the rocker arm 1003 will drop as the liquid level in the connecting oil tank 11 drops. The float valve 10 is gradually closed due to the same principle, and the end of the rocker 1003 is in the groove of the valve core 1005, which pushes the valve core 1005 to move and gradually open the float valve 10. The lubricating oil in the high-positioned lubricating oil replenishing tank 13 flows into the connecting oil tank 11 due to gravity, and the liquid level in the connecting oil tank 11 and the liquid level in the oil pan 1 will rise synchronously. When the liquid level in the connecting oil tank 11 rises, the change in the liquid level of the float body 9 and the action of the support rod 1001 and the rocker 1003, the same principle, gradually close the float valve 10 until the liquid level in the connecting oil tank 11 and the liquid level in the oil pan 1 reach the appropriate position, and the float valve 10 is completely closed. The whole system automatically cycles in this way until the diesel unit stops running.

[0085] During inspection, the operator only needs to record the liquid level in the lubricating oil replenishing tank 13 through the magnetic flap level gauge 16. When the liquid level in the lubricating oil replenishing tank 13 reaches the low value, the lubricating oil can be replenished into the lubricating oil replenishing tank 13. During the entire operation, the liquid level in the lubricating oil replenishing tank 13 is basically static, and there is no oil splashing, etc., which is relatively safe.

[0086] The liquid level keeper 7 maintains the level of the lubricating oil in the oil pan 1. When the oil tank level drops, the float of the liquid level keeper 7 drops and opens the valve, allowing the lubricating oil to flow from the external oil tank and into the oil pan 1 through the liquid level keeper 7. When the oil pan 1 reaches the appropriate level, the float of the liquid level keeper 7 rises and the linked valve closes.

[0087] If the oil replenishment is interrupted and the diesel engine continues to run, some lubricating oil will inevitably be consumed without being replenished. Since the liquid level gauge 8 in the liquid level retainer 7 will transmit the lubricating oil level connected to the fuel tank 11 to the monitoring system in real time, when the liquid level drops to the low liquid level threshold, the monitoring system will issue an alarm signal.

[0088] This embodiment has efficient and stable functions: the lubricating oil online replenishing device can monitor the lubricating oil level in the oil pan 1 in real time, ensuring that the lubricating oil level is relatively stable, thereby ensuring that the diesel generator set can continue to operate efficiently and stably.

[0089] This embodiment has a high degree of automation: the liquid level of the liquid level retainer 7 is automatically controlled by the float valve 10. The buoyancy generated by the float in the lubricating oil links the action of the support rod 1001 and the rocker 1003 to realize the opening and closing of the float valve 10 and automatically realize the oil replenishment operation.

[0090] This embodiment has a highly adaptable function: the height of the float valve 10 in the liquid level retainer 7 is related to the designed liquid level height of the oil pan 1. Different types of diesel engines have different amounts of lubricating oil. It is only necessary to adjust the height of the float valve 10 of the liquid level retainer 7. It is suitable for various types of diesel engines and has strong applicability.

[0091] This embodiment has a high reliability function: the liquid level holder 7 in the online oil replenishing device is connected to or disconnected from the lubricating oil replenishing tank 13 through a liquid level float valve 10. The mechanical linkage structure is simple, mature and reliable, which can ensure the high reliability of the liquid level holder 7, thereby ensuring the reliability and stability of the entire online oil replenishing device.

[0092] This embodiment has a good safety function: when the diesel engine is running, the liquid level of the oil pan 1 will fluctuate. If the oil is directly added to the oil pan 1, accidents such as oil leakage and oil contamination may occur. The online oil adding device ensures the stability of the lubricating oil level in the oil pan 1 by adding oil to the liquid level retainer 7. It indirectly measures the oil level of the oil pan 1 and adds oil, which has better safety.

[0093] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
