Bearings are fixed parts required for mechanical operation. They can keep the shaft in the central position and guide the interlocking movement of other parts. Bearings have a certain service life, and factors such as improper use will accelerate bearing damage. Therefore, regular replacement and maintenance are indispensable. If you don't want to worry about this anymore, you can use the following 7 ways to effectively reduce the cost of mechanical equipment. reduce the risk of damage and extend bearing service life.
1. Proper Lubrication
Regularly replenishing or replacing appropriate, high-quality lubricants to maintain bearing lubrication is the primary key. The oil film surface can minimize wear when components come into contact. For high-speed running equipment, lubricant can also take away the heat generated by the internal friction of the bearing to achieve heat dissipation and cooling effects. Lubricant can use oil or grease, try to choose the lubricant recommended by the original manufacturer (OEM).
Of course, lubricants also have a fixed life span. When the lubricant loses a certain viscosity and lubricity, it will cause agitation, or the bearing may suddenly stop and cause system failure. Therefore, attention must be paid to the replenishment of lubricant.
2. Install Correctly
Since the correct installation of bearings directly affects the service life and mechanical accuracy, correct methods and special tools should be used during the installation and removal of bearings. After installation, it is also necessary to check the installation position, whether the radial clearance of the bearing is just right, flexible, and without vibration, whether the lubricant can flow into the bearing smoothly, and whether there is light leakage around the bearing and shaft shoulder. If there is no light leakage, it means the installation is correct; if there is light leakage, it means the installation is not in place, and the bearing needs to be adjusted to make the two close to each other.
3. Prevent Pollution
Clean bearings: Bearings are precision components. They should be stored horizontally in a clean, dry environment to avoid exposure to any air pollutants. Even minor contamination can damage their performance, so they need to be kept intact before they are ready for use. sealed container.
Clean lubricant: In addition, the lubricant will also contain contaminants after long-term use. In order to prevent the bearing from being worn by particles, the only way to keep it clean is to replace it with new lubricant.
4. Suitable Seal Type
Bearings need to have good sealing performance. Poor sealing will cause dust particles, liquids and other contaminants to enter the bearing, causing wear and tear of parts. Moreover, due to leakage of lubricant, serious product and environmental pollution may occur. Choose a suitable seal. Form can help prevent these problems.
Whether it is temperature or lubricant, many factors will affect the sealing type of bearings, which are mainly divided into contact type, non-contact type, and labyrinth type.
Contact Seals: Also known as lip seals, pressure is exerted on the inner ring of the bearing to bring the seal and the bearing into contact. Because it is in direct contact, there is no gap between the seal and the rotating shaft, and friction and heat are easily generated during rotation, so it is only suitable for medium and low-speed operating environments.
Non-contact Seals: The seal is fixed on the outer ring and does not exert pressure on the bearing of the inner ring. There is no contact between the seal and the bearing components. There is a gap between the seal and the rotating shaft. There is no friction and wear under normal operation. problem and also prevents overheating.
Labyrinth Seals: A more complex type of bearing isolator, a labyrinth seal combines contacting and non-contact sealing elements in a single assembly. The labyrinth seal contains stationary parts and rotating parts, which interlock the two. Its structure forms a small tortuous gap, making it difficult for substances to spill out or penetrate the bearing. Labyrinth seals combine the advantages of contact and non-contact seals, providing the sealing capabilities of contact seals without the frictional overheating problem of non-contact seals.
However, you get what you pay for. Labyrinth seals with higher complexity are of course more expensive than other seals. Therefore, the most suitable sealing form must be determined based on the equipment and operating environment.
5. Adjust Load and Bearing Dimensions
If the bearings do not match the load requirements, wear problems will still occur during high-speed operation. This can be solved by changing the total load of the system or using appropriate bearings.
6. Prevent Rust and Corrosion
Prolonged exposure to water will cause rust and corrosion, and may even fall off during operation, affecting the performance of the mechanical system. Therefore, special attention must be paid to dry storage, and gloves must be worn when handling to avoid contact with sweaty hands.
7. Maintenance Inspection
Finally, be sure to implement regular maintenance and inspections, such as checking the degree of wear, cleaning the bearings with cleaning oil (gasoline, kerosene), etc., so as to ensure the best performance of the bearings and prevent any abnormal conditions in parts or equipment. This is also One of the most basic ways to extend the service life of bearings.
However, prevention is better than cure, so here are simpler and more cost-effective ways to solve the above bearing problems!
8. PTCXPUMP Sealless Magnetic Pump That Can Be Used with Confidence
To reduce the frequency of replacing parts as much as possible when using the pump, it is recommended to use PTCXPUMP sealless magnetic pump. Compared with traditional mechanical shaft seal pumps, the sealless design can effectively avoid leakage and will not cause fluid leakage or industrial safety issues. This aspect is also helpful for improving efficiency. The bearing part is made of SiC (silicon carbide/silicon) material, which has excellent corrosion resistance and high wear resistance; the special design of the internal flow channel of the bearing allows fluid to quickly pass through the interior, which not only has the function of instant lubrication, but also It can quickly take away the mechanical heat generated by operation; because the chemical fluid is not easy to remain, it reduces the problem of the above-mentioned contaminants, and does not need to be replaced as often as ordinary bearings. At the same time, it greatly reduces the possibility of shaft jamming due to fluid crystallization.
In addition, the body and many parts are made of engineering plastics or metals, which have excellent corrosion resistance and are suitable for transporting acid and alkali liquids and other highly corrosive, flammable, explosive or high-temperature and high-risk fluids. The PTCXPUMP sealless magnetic pump series has a variety of models to meet your various operational needs.
Welcome to contact us, we will work with you with a professional team to select the best pump for you according to the actual operating conditions and make the correct selection to help you extend the service life of the pump and reduce production costs.
