When the silver layer on the rotors of a hydraulic pump starts to peel off, it may indicate an underlying failure or problem with the pump. The following is the failure analysis of the silver layer falling off of the hydraulic pump rotor: 1. Wear and tear: Over time, the silver layer on the rotor may wear away due to constant friction and contact with other components. The silver layer provides a protective coating that reduces friction and wear between the rotor and other moving parts. When the silver layer deteriorates or falls off, it causes increased friction and accelerates rotor wear. 2. Insufficient silver plating: If the silver layer is not properly plated onto the rotor during the manufacturing process, poor adhesion and premature peeling may result. Inadequate plating can be caused by factors such as incorrect surface preparation, insufficient coating thickness, or insufficient bonding of the silver layer to the rotor material. 3. Corrosion and chemical reactions: Corrosive substances, pollution or chemical reactions in the hydraulic system can cause the silver layer to degrade. Exposure to chemicals or corrosive liquids can cause the silver coating to crack and subsequently peel off the rotor surface. 4. High temperature: Hydraulic systems operating at high temperatures can cause the silver layer to degrade and fall off the rotor. Elevated temperatures weaken the adhesive properties of the silver layer and accelerate its degradation. 90R075-KA-1-AB-60-S-3-C6-D-04-GBA-35-35-24 90R075KA1AB60S3C6D04GBA353524 90-R-075-KA-1-AB-60-S-3-C6-D-04-GBA-35-35-24 90R075KA1AB60S3C6D04GBA353524 90-R-075-KA-1-AB-60-S-3-C7-D-03-GBA-42-42-20 90R075KA1AB60S3C7D03GBA424220 90-R-075-KA-1-AB-60-S-3-S1-E-00-GBA-26-26-30 90R075KA1AB60S3S1E00GBA262630 90R075-KA-1-AB-60-S-3-S1-E-03-GBA-20-20-24 90R075KA1AB60S3S1E03GBA202024 90-R-075-KA-1-AB-60-S-3-S1-E-03-GBA-20-20-24 90R075KA1AB60S3S1E03GBA202024 90-R-075-KA-1-AB-60-S-3-S1-E-03-GBA-35-35-24 90R075KA1AB60S3S1E03GBA353524 90-R-075-KA-1-AB-80-L-3-C7-E-03-GBA-32-32-28 90R075KA1AB80L3C7E03GBA323228 90R075-KA-1-AB-80-L-3-S1-D-00-GBA-42-42-24 90R075KA1AB80L3S1D00GBA424224 90-R-075-KA-1-AB-80-L-3-S1-D-00-GBA-42-42-24 90R075KA1AB80L3S1D00GBA424224 90-R-075-KA-1-AB-80-L-3-T1-D-00-GBA-29-29-24 90R075KA1AB80L3T1D00GBA292924 90-R-075-KA-1-AB-80-P-3-S1-D-03-GBA-32-32-24 90R075KA1AB80P3S1D03GBA323224 90-R-075-KA-1-AB-80-P-3-S1-D-03-GBA-42-42-24 90R075KA1AB80P3S1D03GBA424224 90R075-KA-1-AB-80-P-3-S1-D-04-GBA-42-42-24 90R075KA1AB80P3S1D04GBA424224 90-R-075-KA-1-AB-80-P-3-S1-D-04-GBA-42-42-24 90R075KA1AB80P3S1D04GBA424224 90-R-075-KA-1-AB-80-P-3-T1-E-03-EBC-35-14-24 90R075KA1AB80P3T1E03EBC351424 90-R-075-KA-1-AB-80-P-4-C6-E-03-GBA-21-21-24 90R075KA1AB80P4C6E03GBA212124 90-R-075-KA-1-AB-80-R-3-T1-E-03-EBC-38-14-24 90R075KA1AB80R3T1E03EBC381424 90-R-075-KA-1-AB-80-R-4-S1-D-03-GBA-35-35-24 90R075KA1AB80R4S1D03GBA353524 90-R-075-KA-1-AB-80-S-3-S1-D-03-GBA-35-35-24 90R075KA1AB80S3S1D03GBA353524 5. Cavitation and Erosion: Cavitation, which occurs when a drop in local pressure causes bubbles to form and collapse, can lead to erosion and damage to the silver layer. If cavitation occurs in a hydraulic system, the repeated bursting of vapor bubbles on the rotor surface can wear away the silver coating. 6. Insufficient lubrication: Insufficient lubrication or improper use of lubricant will increase the friction between the rotor and other parts, causing the silver layer to fall off. Insufficient lubrication reduces the protective barrier provided by the silver coating and leads to direct contact and wear of the rotor with other surfaces. 7. Manufacturing or assembly defects: Manufacturing or assembly defects can also cause the silver layer to fall off. These defects can include inadequate surface preparation, improper plating techniques, or errors during assembly, resulting in a weakened bond between the silver layer and the rotor. 8. Maintenance and service issues: Improper maintenance, such as using abrasive cleaning methods or harsh chemicals, can damage the silver layer and cause it to fall off the rotor. Additionally, neglecting regular maintenance, such as changing lubricants or replacing filters, can lead to degradation of the silver layer. 90R075-KA-1-AB-80-S-4-S1-E-03-GBA-30-30-24 90R075KA1AB80S4S1E03GBA303024 90-R-075-KA-1-AB-80-S-4-S1-E-03-GBA-30-30-24 90R075KA1AB80S4S1E03GBA303024 90-R-075-KA-1-AB-81-S-3-T2-E-00-GBA-35-35-20 90R075KA1AB81S3T2E00GBA353520 90R075-KA-1-AC-80-R-3-S1-E-03-GBA-29-29-24 90R075KA1AC80R3S1E03GBA292924 90-R-075-KA-1-AC-80-R-3-S1-E-03-GBA-29-29-24 90R075KA1AC80R3S1E03GBA292924 90-R-075-KA-1-BB-60-S-4-S1-D-04-GBA-38-38-24 90R075KA1BB60S4S1D04GBA383824 90R075-KA-1-BB-60-S-4-S1-D-09-GBA-35-35-24 90R075KA1BB60S4S1D09GBA353524 90-R-075-KA-1-BB-60-S-4-S1-D-09-GBA-35-35-24 90R075KA1BB60S4S1D09GBA353524 90-R-075-KA-1-BB-60-S-4-S1-E-00-GBA-23-23-24 90R075KA1BB60S4S1E00GBA232324 90-R-075-KA-1-BB-61-P-4-S1-D-03-GBA-23-23-24 90R075KA1BB61P4S1D03GBA232324 90-R-075-KA-1-BB-80-L-3-C7-E-05-GBA-35-35-30 90R075KA1BB80L3C7E05GBA353530 90-R-075-KA-1-BB-80-P-4-S1-D-03-GBA-32-32-24 90R075KA1BB80P4S1D03GBA323224 90R075-KA-1-BB-80-S-3-S1-C-03-GBA-38-20-24 90R075KA1BB80S3S1C03GBA382024 90-R-075-KA-1-BB-80-S-3-S1-C-03-GBA-38-20-24 90R075KA1BB80S3S1C03GBA382024 90-R-075-KA-1-BB-80-S-4-S1-D-00-GBA-23-23-24 90R075KA1BB80S4S1D00GBA232324 90-R-075-KA-1-BB-80-S-4-S1-E-00-GBA-23-23-24 90R075KA1BB80S4S1E00GBA232324 90-R-075-KA-1-BC-60-P-3-C7-D-03-GBA-38-38-24 90R075KA1BC60P3C7D03GBA383824 90R075-KA-1-BC-60-P-3-C7-E-04-GBA-45-45-24 90R075KA1BC60P3C7E04GBA454524 90-R-075-KA-1-BC-60-P-3-C7-E-04-GBA-45-45-24 90R075KA1BC60P3C7E04GBA454524 90-R-075-KA-1-BC-60-P-3-S1-D-00-GBA-26-26-24 90R075KA1BC60P3S1D00GBA262624 9.
