　　Oil seals also known as rotary shaft seals, are essential components used to prevent the leakage of lubricants and fluids in rotating machinery. They are commonly used in various industries such as automotive, manufacturing, and engineering. The design and structure of oil seals can vary significantly depending on their application. One key distinction lies in the presence or absence of a spring. 　　Functionality 　　Oi , l seals with springs and without springs serve the same fundamental purpose, which is to prevent the leakage of fluids and contaminants. However, the inclusion of a spring in oil seals provides additional benefits. The spring serves as a radial load component, ensuring a constant pressure on the sealing lip against the shaft, thereby enhancing the sealing efficiency. On the other hand, oil seals without springs rely solely on the interference fit between the seal and the shaft to maintain the sealing integrity. 　　Sealing Efficiency 　　The presence of a spring in oil seals significantly improves their sealing efficiency. The spring helps to compensate for any wear or misalignment that may occur between the shaft and the seal over time. It ensures a continuous radial force against the shaft, maintaining a tight seal and preventing fluid leakage. In contrast, oil seals without springs may experience reduced sealing efficiency due to wear or misalignment, leading to potential leaks. 　　Installation and Assembly 　　Oil seals with springs are relatively easier to install and assemble compared to their counterparts without springs. The spring provides a self- adjusting feature, allowing for easier alignment and positioning during installation. The spring also helps to maintain a constant pressure on the sealing lip, ensuring a secure fit. Conversely, oil seals without springs require more precise alignment and careful installation to achieve an effective seal. 　　Applications 　　O , il seals with springs are commonly used in applications where there is a high degree of shaft misalignment or vibration. The spring compensates for any shaft movement, ensuring a constant radial force on the sealing lip. This makes them suitable for use in heavy machinery, automotive engines, and industrial equipment. Oil seals without springs, on the other hand, are used in applications where shaft misalignment and vibration are minimal, such as pumps, compressors, and light-duty machinery. 　　Longevity and Durability 　　Oil seals with springs generally have a longer lifespan and higher durability compared to those without springs. The spring helps to distribute the load evenly on the sealing lip, reducing wear and tear. It also provides additional support and stability to the seal, preventing deformation or damage. Oil seals without springs may experience faster wear and reduced durability, especially in applications with higher shaft misalignment or vibration. 　　Oil seals with springs offer improved sealing efficiency, easier installation, and better performance in applications with shaft misalignment or vibration. On the other hand, oil seals without springs are suitable for applications with minimal misalignment and vibration. Careful consideration of the specific application requirements is essential in selecting the appropriate oil seal type.

Kuplin is from a Russian hydraulic equipment manufacturing company, he has purchased hydraulic valve blocks from China for a long time, which is also relatively smooth. However, a hydraulic valve block he purchased at the end of last year put him into a hard situation. A batch of hydraulic climbing cars sold by their company were complained by customers. During the routine maintenance of the hydraulic system, several cartridge valves on several equipment cannot be taken down, the nose end is stuck in the socket of the hydraulic valve blocks, and there is a small amount of leakage around the socket. The hydraulic valve block manufacturer replied that when processing the hydraulic valve blocks, the technician processed the nose end of the socket into a conical surface, which made it easy to install and difficult to take down, and also affected the seal, resulting in a small amount of leakage. The hydraulic valve block can be replaced free of charge, but no one will bear the loss of those hydraulic cartridge valves that cannot be disassembled. After the boss learned that, he asked Kuplin to find a new manufacturer of hydraulic valve blocks. Kuplin contacted more than 10 new factories and required that there was no abnormality in the processing of valve holes of each hydraulic valve block. After a round, he did not find any suitable supplier of hydraulic valve blocks. Kuplin began to worry. By chance, Kuplin met his old friend Petrov and learned about AAK's ability to process hydraulic valve blocks during the communicating with each other. After several communications with him, AAK started to make samples directly. 1 month later, AAK sent the hydraulic valve blocks. Petrov informed by email that their engineer specially inspected each valve hole, and the tolerance was controlled 100% without deviation. He wanted to know how AAK achieved it? AAK hydraulic valve block has no deviation from the processing of the installation socket, is due to 3 strict points: 1. For tool inspection, it is in the charge of a specially assigned person, who regularly inspects each tool equipped in each machining center to confirm whether there are cuts or cracks on the leading edge of the tool, so as to avoid the problem of machining finish caused by tool wear or damage. 2. Clean the cutter. AAK uses a diamond file to remove the debris of the cutter material and ensure that the positioning shoulder on the reamer remains sharp. AAK will check the size of the ground tool based on the tool positioning shoulder to ensure that the depth and diameter meet the processing requirements. 3. After machining, use diameter gauge and thread gauge to check the dimensional accuracy according to the requirements of the socket drawing, and carry out the final socket dimensional check. Especially, the nose part of the cartridge valve socket will be measured from the front end of the nose to the supporting end of the nose, so as to ensure that there is no cone at the nose. AAK hydraulic valve block is easy to install and take down without deviation, and 100% free of burrs. You are welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak300

Palencia is from Spain and has little cooperation with AAK. Some time ago, he emailed us to discuss about the blind hole of hydraulic valve blocks. After several rounds of email communication, it was learned that in the second half of last year, Palencia tried samples with more than 10 hydraulic valve manufacturers because the blind hole quality of the hydraulic valve block was not up to standard. The samples of the hydraulic valve blocks either had a bell mouth in the blind hole, or the surface roughness of the hole wall was not up to standard. It wasted him 4 weeks before and after, moreover, the development fees paid were not refund, which made him very depressed. According to the drawing of hydraulic valve block provided by Palencia, the processing difficulties are mainly concentrated in the blind hole. The processing hole diameter of this hydraulic valve block is small, and the depth is more than 40mm. Only the cutter bar with slender shaft can be used, but the cutter can not all pass through the hole, resulting in easy deformation of the inner hole diameter and axial taper and ovality. In this way, the bell mouth is easy to appear at the hole depth of 10 ~ 20mm, and the surface roughness of the hole wall can not be guaranteed, too. AAK innovated the technology 3 years ago for the difficulties of blind hole processing of hydraulic valve blocks. I directly replied to Palencia that this is a difficult processing, but it is not difficult for AAK. You can directly test the order. If our goods does not meet the requirements of the drawings, the development fee can be refund. 4 weeks later, AAK sent 5 samples of hydraulic valve blocks. 2 months later, Palencia placed the annual order of 600 hydraulic valve blocks, with goods shipped every 2 months. Their engineers were surprised why AAK succeeded in making samples at one time, while all other hydraulic valve manufacturers failed previously? For the processing of small and deep blind holes in the hydraulic valve blocks, most hydraulic valve manufacturers cannot meet the high-precision requirements, while AAK has a high-precision CNC processing center imported from Switzerland, and adopts the technology of extruding holes with a patented bladed extruding knife independently developed by AAK. And this processing method has 3 advantages. Most hydraulic valve manufacturers are difficult to master this technical detail in operation, but AAK mastered it 3 years ago. 1.The blind hole of the hydraulic valve block adopts a bladed extruding knife. Through longitudinal feeding, a moderate extruding force is applied to the workpiece surface, and then through the rotation of the knife or workpiece, the height difference between the crest and trough of the knife mark is reduced, and the surface roughness is optimized. 2.During the processing, the hole surface produces slight cold work hardening, which improves the physical properties of the blind hole surface and improves the hardness and wear resistance of the blind hole surface. 3.After machining, the roughness of the hole can reach Ra value of 0.8 ~ 0.4μm. The ovality circle error is 0.01 ~ 0.02mm, the taper error is 0.01 ~ 0.025mm, and the dimensional accuracy of the hole can be controlled within 0.01mm. AAK hydraulic valve blocks, blind hole processing with unique skills, and also with 3 types of pressure test standards to guarantee quality, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-299
