Pump thrust pad bearings Details

    The mode of operation of tilting pad thrust bearings is well established.The main principles followed in this range are based on those of the range of non-equalized thrust bearings.The essential difference, that of equalization, is also a well established concept. This compact range offers full load capability,equivalent to or greater than other designs,whether equalized or non-equalized.
    This bearings given speical design to ensure optimum load distribution and trouble free operation,and also take advantage of other features such as offset pivots to achieve the best possible performance. Key features make the the bearing superior to other directed lubrication bearings in use:
1.Oil feed tubes connecting to the shoes ensures that cool oil does not bypass the film;
2.Large oil flow passages eliminatesmall-hole clogging;
3.No oil seal rings are required, lowering power loss and simplifying design and installation;
4.The bearing does not require (but can use) special, higher pressure lube systems typi-cally needed for spray lubrication.
    For new applications as well as for retrofie ,the thrust and journal bearings provide the ollowing benefits:
1.Lower friction power loss for increased overall machine efficiency;
2.Lower operating temperature and increased load capacity;
3.Lower oil flow requirements for smaller lubricating oil systems and lower capital costs;
4.Ability to optimize for maximum load capacity or to minimize power loss.

Do compressor thrust pad bearings need to be coordinated with the bearing seat?

The compressor thrust pad bearing is an important part of the compressor. It is responsible for withstanding the axial thrust and ensuring the normal operation of the compressor. In order to ensure the transmission and load-bearing capacity of axial thrust, coordination with the bearing seat is required. As an important component for carrying and fixing bearings, bearing seats not only need to provide sufficient support, but also need to protect the bearings from external damage.
Before installing the bearing seat, preparations need to be made. First, the bearing seat and other related parts need to be cleaned to ensure that there are no impurities and dirt. Then, check whether the surface of the bearing seat is flat and whether there are signs of damage or wear. If any problem is found, the bearing seat needs to be repaired or replaced in time. At the same time, it is also necessary to check whether the bore diameter of the bearing seat and the outer diameter size of the bearing meet the requirements to ensure matching accuracy.
When adjusting the bearing seat, you need to pay attention to the following points. First of all, it is necessary to maintain the matching accuracy between the bearing seat and the compressor thrust pad bearing. Fitting accuracy refers to the gap between the bearing seat and the bearing. This gap needs to be adjusted according to the actual situation. If the gap is too large, the connection between the bearing seat and the bearing will become loose, affecting the load-bearing capacity and stability; if the gap is too small, the friction and wear of the bearing will increase, affecting the service life. Therefore, when adjusting the bearing seat, it is necessary to make precise adjustments according to specific requirements to ensure that the gap between the bearing seat and the bearing is appropriate.
Secondly, it is necessary to ensure that the bearing seat supports and positions the compressor thrust pad bearing accurately and reliably. The main function of the bearing seat is to carry axial thrust and support the bearing. Therefore, it needs to have good rigidity and stability. When installing the bearing seat, appropriate tools and methods should be used to ensure that the connection between the bearing seat and the machine base is tight and reliable, and to avoid deflection or deformation. In addition, attention should be paid to the lubrication and cooling of the bearing seat to ensure its normal operation and service life.
The compressor thrust pad bearing needs to be coordinated with the bearing seat to ensure stable and reliable operation. When installing and adjusting the bearing seat, attention needs to be paid to the accuracy of the fit and support positioning to ensure that the bearing seat effectively supports and protects the bearing. Only in this way can the normal operation and service life of the compressor be ensured.

Will unbalanced load cause compressor thrust pad bearings to vibrate?

When the compressor rotor is unbalanced or the bearings are poorly installed, unbalanced loads will occur. Unbalanced load refers to the uneven mass distribution of the rotor during rotation, which causes the centrifugal force generated by the rotor to be unbalanced. This unbalanced load will have a negative impact on the normal operation of the compressor.
Unbalanced loads can cause compressor thrust pad bearings to vibrate. Thrust pad bearings are mainly used to withstand the axial force generated during the rotation of the compressor rotor. When the unbalanced load of the rotor is too large, the thrust pad bearing cannot effectively withstand this force, causing vibration and imbalance in the bearing. Under the action of vibration, bearings are prone to wear and damage, and in severe cases, the thrust pad bearing may even break. As a result, the operational stability and life of the entire compressor will be affected.
Unbalanced loads can increase compressor vibration. The unbalanced load generated during the rotation of the rotor will increase the vibration of the rotor. This vibration will not only be transmitted to the thrust pad bearings, but also to other components of the entire compressor through the bearings, causing the vibration of the entire compressor to intensify. Vibration increases friction and wear, making machine operation more difficult and unstable. At the same time, vibration will also cause noise, causing interference and impact on the surrounding environment.
The way to solve this problem is to first perform dynamic balancing, that is, to adjust the mass distribution of the rotor to be uniform by adding mass on a trial basis. This can reduce or even eliminate the existence of unbalanced loads, improve the balance of the rotor, and reduce the occurrence of vibration. Secondly, ensure that the installation quality of the bearings is good. The correct installation of bearings can ensure their good working condition, reduce vibration and noise, and extend the service life of the bearings. In addition, regular maintenance and upkeep of the compressor is also very important. Regular inspection and replacement of key components such as bearings can detect and solve potential problems in time to ensure the normal operation of the compressor.
If the compressor rotor is unbalanced or the bearings are poorly installed, it will cause unbalanced loads, resulting in increased vibration and vibration of the compressor thrust pad bearings. In order to solve this problem, it is necessary to perform dynamic balancing and ensure good installation of the bearings, as well as regular maintenance and upkeep to ensure the normal operation of the compressor.
