　　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

Fabian from the Netherlands left a message on AAK website last month: what is the reason for the hydraulic direction control valves stuck? In general, the processing roughness of valve spool and valve hole is poor, or it is caused by radial unbalanced hydraulic pressure caused by inconsistent coaxiality. AAK adopts mirror grinding for the finishing of valve spool and valve hole, and the surface roughness can reach AO=Ra0.08μm, which is more than 10 times that of its peers. According to Fabian, in the second half of last year, the hydraulic directional control valves of the trial order got stuck, which made them very anxious. Thia hydraulic directional control valve is used on the hydraulic power unit. After the equipment is commissioned and operated continuously for 48 hours, the pressure supply of the equipment is abnormal. The engineer disassembled and found that the contact surface between the valve spool and the valve hole of the hydraulic directional control valve is too rough, so the hydraulic directional control valve needs to be replaced, and the surface roughness is required to reach AO=Ra0.5μm or below. The original manufacturer fed back that the roughness of valve spool and valve hole Ra1.0μm was their limit. Fabian was very depressed and had to find a new manufacturer of hydraulic directional control valve. Fabian contacted more than 10 factories, and none of them confirmed that the RA of the contact surface between the spool and the valve hole of the hydraulic direction control valve can be controlled at 0.5μm. They also told that it was not necessary to control the Ra value when it was stuck, and Fabian would have no direction. He found AAK Hydraulic Valves and left a message to ask the reason why the hydraulic directional control valve was stuck. According to Fabian's description and the drawing of this hydraulic directional control valve, I think their engineers' new requirements for Ra value are reasonable. AAK is able to control Ra value well. We recommended that Fabian directly test the order. If our Ra value does not meet the standard or the hydraulic directional control valve is stuck, we can refund it in full. After 35 days, AAK sent 10 samples of hydraulic directional control valves. Two weeks later, Fabian informed by email that no abnormality was found during the commissioning of the AAK hydraulic directional control valves. Their engineers specially detected the Ra value of the contact surface between the valve spool and the valve hole, and were surprised that it is Ra0.08μm, which is more than 10 times more accurate than that of peers, and more than 6 times what they require. The surface finish of the valve spool and valve hole directly determines the flexibility of the hydraulic direction control valve, and most hydraulic valve manufacturers tend to ignore this small detail in the processing process. AAK hydraulic direction control valve spool and valve hole are precision machined with the NP520X-F full-automatic universal grinder of Japan's Long Island Precision grinding machine, which can achieve μ level feed mirror grinding, the surface of the machined valve spool is like a mirror. AAK hydraulic directional control valves, no jamming, you can also have a small try! https://www.aakindustry.com/info-d , etail/hydraulic-directional-control-valves- aak , 298

Last month, a Brazilian hydraulic valve customer informed me that due to domestic political reasons, they had stopped importing hydraulic valves. I was a bit surprised at the time, as he had been purchasing hydraulic Sequence Valves from AAK. Two weeks later, it was learned that this hydraulic valve customer had applied for bankruptcy. Fortunately, the hydraulic Sequence Valves supplied by AAK are all prepaid. It was heard that the other two hydraulic valve manufacturers in Ningbo have over 70,000 US Dollars of payment for hydraulic Sequence Valves not recovered. Lucio and I met 3 years ago. After purchasing hydraulic Sequence Valves from AAK for a period of time, he asked me to accept a TT NET 60 days of payment terms, but I politely declined, then he moved a portion of the hydraulic Sequence Valve orders to peers in Ningbo, with several high-precision hydraulic Sequence Valves continuing to be purchased from AAK. When Lucio initially discussed the payment terms with me, he confidently said, "I won't owe you any money, even if the finance department runs out of money, I will pay you for the hydraulic Sequence Valves”. I hesitated a bit, but on second thought, what kind of guarantee should I use? After all, this is not his personal business, but the company's business. Last week, my aunt came to borrow money from my mother because my cousin borrowed an online loan. If she doesn't repay it, there will be big trouble. My aunt hopes her elder sister can lend 500,000 yuan to her. My aunt cried and said, 'I want to save my son even I bankrupt myself. '! I know my cousin's addiction to gambling, which is a bottomless pit. 2 years ago, my aunt had already repaid my cousin's gambling debt of over 200,000 yuan. Now, his behavior repeated again and borrowed online loan unexpectedly, and all his bank cards have been overdrawn, creating a hole of 500,000 yuan. My mother doesn't have much money in her hands. Seeing that her younger sister is pitiful, she wants me to help my cousin. My aunt asked me to believe in her. She will return money definitely. My mother certainly believes in her sister and is willing to guarantee this loan. I asked my aunt when to return it? Aunt said: 5 years at most! I answered: Of course I believe in you, but do you believe in me? If you believe me, my cousin has a property with a market value of 600,000 yuan, but now the property is not very prosperous. If you are eager to sell it, it will be 500,000 yuan. I can lend my cousin 500,000 yuan, but he must transfer the property to me. When he returns the money to me, I will transfer the property back to him. Even if the price of the house has increased, and I don't want any more money. Even if the ownership is transferred to me, I don't need rent. If he doesn't pay back in 5 years, then I'll sell this house! I asked my aunt to go back and discuss with my cousin. My aunt cried and said, 'If the house is gone, what will he do in the future?'? This won't work. Even if your cousin doesn't pay you back, I will definitely pay you back if I smash the pot and sell iron! I said to my aunt: I understand, you are preparing to smash my pot and sell my iron! Do you think my money was brought by the wind? If you don't agree to this plan, then we don't have to talk about it! This is also a unique feature of China, where one likes to borrow money from others and vows to repay by smashing pots and selling iron, but there is no guarantee. Many times, doing business and living are the same feeling. Without effort or trust, how to close a hydraulic Sequence Valve deal? The payment of customers is also the same. Customers who pay attention to quality often make payments easily, which is what they say and do.

What is the value of hydraulic valve manufacturers? How should I view the business of my company?   The starting point of all businesses is to benefit users. To benefit users is to provide "value" and "benefits" to users. When our R & D department wants to develop a new hydraulic valve, I ask them to know what function is very important, but also to figure out what users want, and creatively meet their needs.   The core responsibility of the operator of the hydraulic valve manufacturer is to seek the potential. Potential energy is to find the enhanced circuit of enterprises and businesses and make the flywheel rotate. How do I find the enhancement circuit of AAK Hydraulic Valves?   As an operator of hydraulic valve manufacturers, the most important core for me is reputation. But what is driving the improvement of "reputation"? Daily articles about the difficult and miscellaneous problems of hydraulic valves, such as how to help customers solve the problems that peers can't solve. So, what is driving the emergence of articles? Professional skills, on paper, will only be laughed at. It must sink into research and development, innovation, production, materials, equipment, technology, to analyze specific situations and solve specific problems, so as to be professional. However, what is promoting the accumulation of "professional skills"? Reputation. Only with an excellent reputation, can there be many high-quality hydraulic valve customers, allowing you to accompany, so that you can gain a lot of knowledge and practice. Did you find it? "Reputation - (+) > professional skills - (+) > Article - (+) > reputation", an enhancement loop, surfaced.   When I draw my flywheel, I am a very clear standard in my heart. I decided not to do anything other than pushing the flywheel. As long as it's not pushing the flywheel, don't do it. Once, an old customer introduced me to an Indian customer who can purchase 1,800 hydraulic valves every month. I was very moved, but I declined this Indian customer. Because the hydraulic valves he needs to purchase are very common market goods, and most hydraulic valve manufacturers can do it well. Helping him solve the supply of hydraulic valves may not help me improve my reputation. In terms of customers, we are the supplier of HydraForce for 9 consecutive years, which has improved my reputation. This is on my flywheel.   The essence of business is transaction, and in the transaction, you can only exchange something with the value you provide. For example, if you offer something worth 100 yuan, theoretically you can only get back 100 yuan. If you occasionally get more money than the value you offer, it will be taken away one day. Any transaction is not just completed one time.   Hydraulic valve trading is also to exchange commodities for money. The manufacturer takes the hydraulic valve, the customer takes the money, and we will exchange it. However, I think there is a more advanced transaction before this transaction. This transaction is not to exchange goods for money, but to exchange content for time. For example, I wrote an article on hydraulic valves, and then you spent some time here because you were attracted by the content of AAK Hydraulic Valves. The transaction of exchanging goods for money actually takes place in time. For example, you take time to watch my short video, in which I introduced a hydraulic valve, and then you came to inquire.   The first transaction is actually the soil of the second transaction. Only when it occupies the customer's mind or time first, it is possible to trade goods with him. However, the vast majority of hydraulic valve manufacturers only pay attention to the second transaction and look everywhere for the transaction of commodity for money. AAK Hydraulic Valves constantly release content, so that more customer cases can help those customers who have suffered losses in purchasing hydraulic valves, so as to consolidate the trust of AAK.   AAK Hydraulic Valves, only for reputation. https://www.aakindustry.com/inf , o-detail/hydraulic-valve-manufacturers-aak297
