When the shaft seal contacts the bearings of the plunger pump, some precautions should be taken to ensure proper operation and service life. 1. Lubrication: Ensure that the bearings are properly lubricated to minimize friction and wear. Adequate lubrication helps reduce heat generation and prolongs bearing and shaft seal life. Follow the manufacturer's recommendations for the type and amount of lubricant to be used. 2. Proper Alignment: Make sure the shaft seal and bearing are properly aligned. Misalignment can cause excessive stress and uneven wear on both components. Use proper alignment techniques or tools to achieve the recommended alignment tolerances. 3. Avoid excessive load: Minimize excessive axial or radial load on the bearing. Excessive loads can cause premature bearing failure and increased shaft seal wear. Verify that the loads applied to the bearing are within the design limits specified by the manufacturer. 4. Avoid contamination: Prevent contaminants from entering the bearing area. Contaminants such as dirt, dust or moisture can impair the performance of bearings and shaft seals. Use proper sealing mechanisms and consider implementing protective measures, such as dust covers or seals, to minimize the risk of contamination.

Temperature control: Ensure that the working temperature of the bearing and shaft seal is kept within the specified range. Excessive temperatures will accelerate wear and reduce the effectiveness of seal materials. To maintain optimal temperature conditions, appropriate cooling mechanisms or thermal insulation may be required. 6. Periodic inspection and maintenance: Periodically inspect bearings and shaft seals for any signs of wear, damage or leakage. Address any problems promptly by replacing worn components or repairing defective seals. Regular maintenance, such as cleaning and relubrication, helps to extend the life of bearings and shaft seals. 7. Follow Manufacturer's Guidelines: Always follow the manufacturer's guidelines and recommendations for the specific displacement pump model and components being used. Manufacturer's instructions may include specific precautions and maintenance procedures tailored to the bearing and shaft seal design. 8. Avoid Excessive Shaft Runout: Excessive shaft runout can lead to uneven loading and premature wear of bearings and shaft seals. Follow the manufacturer's specifications and use proper installation techniques to ensure that the shaft has minimal runout. If you find that the runout is too large, please solve it immediately to prevent damage to the bearings and seals. 9. Monitor shaft seal leakage: regularly monitor the shaft seal for signs of leakage. Excessive or abnormal leakage can indicate damaged or failed seals, leading to contamination and premature bearing wear. Replace or repair seals as needed, promptly addressing any seal leaks.

Consider shaft seal material: Select a shaft seal that is compatible with the specific operating conditions and fluids handled by the piston pump. Different sealing materials have different resistance to chemicals, temperature and pressure. Make sure the chosen seal material can withstand the operating conditions of the pump to prevent premature failure. 11. Control system pressure: Avoid excessive pressure peaks or fluctuations in the hydraulic system. High pressure surges place additional stress on bearings and seals, resulting in accelerated wear. Use a pressure relief valve or other control mechanism to maintain a steady and controlled pressure level in the system. 12. Correct installation: Install bearings and shaft seals according to the manufacturer's recommended steps. Improper installation techniques may result in misalignment, inadequate sealing, or component damage. Use proper tools and techniques to ensure accurate and safe installation. 13. Maintenance of the shaft seal: regularly clean and check the shaft seal for maintenance. Remove any built-up debris or contamination that may impair its performance. Follow the manufacturer's recommendations for seal maintenance, including the use of compatible cleaners and lubricants.
