Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an oil filter tube. Background Art

[0002] With a series of improvements and tests to improve the quality of twin-cylinder engines, it was found that due to the clearance between the oil filter pipe and the oil filter seat, 27.2% of the lubricating oil in the BDA20F twin-cylinder diesel engine did not enter the oil circuit of the oil filter seat to the radiator for heat dissipation, but directly entered the main oil channel of the twin-cylinder diesel engine through the gap between the oil filter pipe and the oil filter seat. The oil temperature increased by 8.7%, causing the oil pressure to drop by 120Kpa, resulting in insufficient lubrication of the twin-cylinder diesel engine oil circuit and a power drop of 11.1%. Therefore, in order to solve the above problems, we proposed the oil filter pipe. Utility Model Content

[0017] The embodiment of the present application effectively solves a series of improvements and tests as the quality of two-cylinder engines is improved by providing an oil filter pipe. It was found that due to the clearance between the oil filter pipe and the oil filter seat, 27.2% of the lubricating oil in the BDA20F two-cylinder diesel engine did not enter the oil circuit of the oil filter seat to the radiator for heat dissipation, but directly entered the main oil channel of the two-cylinder diesel engine through the gap between the oil filter pipe and the oil filter seat. The oil temperature increased by 8.7%, causing the oil pressure to drop by 120KPa, resulting in insufficient lubrication of the oil circuit of the two-cylinder diesel engine and a power drop of 11.1%.

[0018] Example

[0019] according to Figure 1 and Figure 2 As shown, the technical solution in the embodiment of the present application effectively solves a series of improvements and tests as the quality of the two-cylinder engine is improved. It was found that due to the clearance between the oil filter pipe and the oil filter seat, 27.2% of the lubricating oil in the BDA20F two-cylinder diesel engine did not enter the oil circuit of the oil filter seat to the radiator for heat dissipation, but directly entered the main oil channel of the two-cylinder diesel engine through the gap between the oil filter pipe and the oil filter seat. The oil temperature increased by 8.7%, causing the oil pressure to drop by 120Kpa, resulting in insufficient lubrication of the oil circuit of the two-cylinder diesel engine and a power drop of 11.1%. The overall idea is as follows:

[0020] In response to the problems existing in the prior art, the utility model provides an oil filter tube, including an oil filter seat main body 1, a filter tube mounting hole 11 is provided on the oil filter seat main body 1, an oil filter tube body 2 is arranged in the filter tube mounting hole 11, a sealing ring mounting groove 21 is opened on the oil filter tube body 2, and a O-shaped sealing ring 22 is assembled between the sealing ring mounting groove 21 and the filter tube mounting hole 11, wherein the specifications of the O-shaped sealing ring 22 comply with GB / T3452.2-2007, and the size of the O-shaped sealing ring 22 is φ15×2.65F, and the O-shaped sealing ring 22 is made of high-temperature resistant fluororubber. The O-shaped sealing ring 22 that complies with the GB / T3452.2 standard is selected. This O-shaped sealing ring is made of high-temperature resistant fluororubber material, which not only has good elasticity and wear resistance, but also can maintain stable sealing performance in high temperature environment. The O-shaped sealing ring we selected has a size of φ15×2.65F, which ensures close fit with the sealing ring mounting groove and further improves the sealing effect.

[0021] The width of the sealing ring mounting groove 21 is 3.2mm, the diameter of the sealing ring mounting groove 21 is 15.1mm, the length of the oil filter pipe body 2 is 70mm, the inner diameter of the oil filter pipe body 2 is changed from the original φ12 to φ9, and the outer diameter of the oil filter pipe body 2 is φ13.86. The improved design of the oil filter pipe body 2 is precisely matched and installed with the selected high-temperature resistant fluororubber O-shaped sealing ring 22. This process not only requires the operator to have professional skills and experience, but also requires the use of special tools and equipment. After assembly, the entire combination is closely matched and fixed to the oil filter seat body 1. This assembly process ensures the complete sealing of the filter pipe mounting hole 11, effectively preventing oil leakage.

[0022] Working principle:

[0023] When the oil filter pipe is in use, the improved oil filter pipe body 2 and the O-shaped sealing ring 22 made of high-temperature resistant fluororubber are further assembled and installed. After assembly, it is matched with the oil filter seat to realize the sealing device, ensuring that the oil no longer flows directly between the oil filter pipe and the oil filter seat, but is introduced into the radiator oil circuit through the oil filter seat according to the oil circuit designed for the two-cylinder diesel engine, and after cooling in the radiator, it enters the main oil channel of the two-cylinder diesel engine to work.

[0024] In actual applications, in order to ensure the optimal sealing performance of the oil filter tube, we have carried out careful design and improvement. First, in the middle part of the oil filter tube body, we have specially added a delicate and powerful sealing ring installation groove 21. The width of this installation groove is precisely set to 3.2 mm, which ensures the stability of the sealing ring installation, and its diameter reaches 15.1 mm, ensuring sufficient installation space. This design not only fully considers the installation requirements of the sealing ring, but also takes into account the overall structural strength and stability of the oil filter tube body.

[0025] In order to ensure the reliability and durability of the sealing effect, we strictly selected the O-shaped sealing ring 22 that meets the GB / T3452.2 standard. This O-shaped sealing ring is made of high-temperature resistant fluororubber material. This material not only has good elasticity and wear resistance, but also can maintain stable sealing performance in high temperature environments. The size of the O-shaped sealing ring we selected is φ15×2.65F, which ensures a close fit with the sealing ring installation groove and further improves the sealing effect.

[0026] During the assembly and installation process, we precisely matched and installed the improved oil filter pipe body 2 with the selected high-temperature resistant fluororubber O-ring 22. This process not only requires the operator to have professional skills and experience, but also requires the use of special tools and equipment. After the assembly is completed, the entire combination is closely matched and fixed to the oil filter seat body 1. This assembly process ensures the complete sealing of the filter pipe mounting hole 11, effectively preventing oil leakage.

[0027] Through such design improvements and precise matching, we have successfully achieved complete sealing of the filter pipe mounting hole 11. When the engine oil flows through the oil filter seat body 1, it can flow according to the oil circuit designed for the two-cylinder diesel engine. First, the engine oil is introduced into the radiator oil circuit. After the cooling effect of the radiator, the temperature of the engine oil is effectively reduced. Subsequently, the cooled engine oil enters the main oil channel of the two-cylinder diesel engine, providing a stable oil supply for the normal operation of the engine. This process not only ensures the normal operation of the engine, but also increases the oil pressure and the power output of the engine. At the same time, due to the reduction in oil temperature, the wear and failure rate of the engine are also effectively reduced, thereby extending the service life of the engine.

[0028] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
