The influence of contaminated hydraulic oil on the relative volume flow and the wear of friction parts in aviation piston pumps can have multiple adverse effects. Here are some key considerations: 1. Reduced flow: Contaminants in the hydraulic oil can cause blockage or restriction of the flow path of the plunger pump, resulting in a decrease in relative volumetric flow. Solid particles, such as dirt, debris or metal shavings, can accumulate in pump valves, cylinders or other flow passages, increasing friction and resistance to fluid flow. This results in reduced pump efficiency and a reduction in the overall volume of fluid being pumped. 2. Valve sticking and leaking: Contaminants can interfere with the proper operation of pump valves. When particles or debris become trapped between valve components, they can cause the valve to stick or not close properly. This can cause internal pump leakage, reducing effective volumetric flow and negatively affecting pump performance. 3. Increased wear: Contaminated hydraulic oil containing abrasive particles will accelerate the wear of the friction parts of the pump. As fluid moves through the pump, abrasive contaminants can cause corrosion, scoring or pitting on surfaces such as plungers, cylinders or valve seats. This wear can lead to increased clearance between mating surfaces, resulting in reduced pump efficiency, increased fluid leakage and potential pump failure. 4. Seal damage: Contaminants can also damage the seals used in piston pumps. Abrasive particles can cause the sealing surfaces to wear or cut, affecting their ability to provide an effective seal. This can cause fluid leakage between the high and low pressure sides of the pump, reducing volumetric flow and potentially causing other operational problems. 90-L-130-KT-5-NN-80-P-3-F1-H-03-GBA-38-38-24 90L130KT5NN80P3F1H03GBA383824 90-L-130-MA-1-AB-80-L-3-F1-H-03-GBA-38-38-24 90L130MA1AB80L3F1H03GBA383824 90L130-MA-1-AB-80-P-3-F1-F-03-GBA-45-45-24 90L130MA1AB80P3F1F03GBA454524 90-L-130-MA-1-AB-80-P-3-F1-F-03-GBA-45-45-24 90L130MA1AB80P3F1F03GBA454524 90L130-MA-1-BB-80-L-4-F1-H-03-GBA-35-35-30 90L130MA1BB80L4F1H03GBA353530 90-L-130-MA-1-BB-80-L-4-F1-H-03-GBA-35-35-30 90L130MA1BB80L4F1H03GBA353530 90-L-130-MA-1-BB-80-S-3-C8-F-04-GBA-42-42-24 90L130MA1BB80S3C8F04GBA424224 90L130-MA-1-BC-80-R-3-F1-F-03-GBA-42-42-24 90L130MA1BC80R3F1F03GBA424224 90-L-130-MA-1-BC-80-R-3-F1-F-03-GBA-42-42-24 90L130MA1BC80R3F1F03GBA424224 90-L-130-MA-1-BC-80-R-4-F1-F-03-GBA-35-35-24 90L130MA1BC80R4F1F03GBA353524 5. Component damage and failure: If the pollution is serious or unresolved, it may cause more serious damage or failure of the friction parts in the pump. Increased wear, loss of sealing effectiveness and impaired fluid flow can lead to component fatigue, fracture or catastrophic failure. This could result in complete loss of pump function and possible damage to other system components. To mitigate the effects of contaminated hydraulic fluid, it is critical to implement proper maintenance and contamination control measures: - Regular analysis and filtration of hydraulic oil: Regular monitoring of the cleanliness and condition of hydraulic oil helps to detect and solve contamination problems in a timely manner. Effectively replacing and purging filter systems and fluids can reduce the presence of contaminants and keep pumps running properly. - Proper Fluid Handling and Storage: Following proper fluid handling, storage and cleaning procedures can minimize the entry of contaminants into the hydraulic system. This includes using clean containers, avoiding cross-contamination, and keeping foreign objects out during rehydration. - Routine maintenance and inspection: Routine inspection and maintenance of the plunger pump, including cleaning, flushing and lubrication, will help to remove any accumulated contamination and prevent its adverse effect on relative volume flow and wear of friction parts. This also includes inspecting and replacing worn seals or components as needed. - Fluid compatibility and selection: Use hydraulic oil compatible with pump materials and anti-pollution to help reduce potential negative effects. It is important to consult the pump manufacturer for recommendations and specifications regarding fluid selection to ensure optimum performance and service life. 6. Changes in fluid viscosity: Contaminants in hydraulic oil can change the viscosity of the fluid, thereby affecting the relative volume flow. Contaminants such as water, air bubbles or degraded additives can change the viscosity of the fluid and affect its ability to flow smoothly through the pump. Changes in viscosity can cause fluctuations in pump performance, affecting volumetric flow and potentially causing system inefficiency or instability. 7. Cavitation and Erosion: Contaminated hydraulic fluid increases the likelihood of cavitation in the pump. Cavitation occurs when the pressure drops below the vapor pressure of the fluid, causing bubbles to form and collapse. These collapsing bubbles create intense localized pressure waves and erosion on the surfaces of friction components, leading to wear and degradation. Cavitation can significantly affect pump performance and reduce relative volume flow. 8. Chemical degradation: Contaminants in hydraulic oil, such as moisture or chemical impurities, can cause chemical degradation of the fluid itself. Chemical reactions, oxidation or acid formation may occur, resulting in a decrease in the fluid's properties, including its ability to lubricate. As a result, the friction and wear between the friction parts of the pump will increase, the flow rate relative to the volume will be further reduced, and may lead to premature failure of the components. 9. Monitoring and Maintenance Practices: Implementing effective monitoring and maintenance practices is critical to timely detection and resolution of contamination issues. Regular fluid analysis, including particle counts and fluid condition monitoring, helps determine contamination levels and implement appropriate corrective actions. Implementing a proactive maintenance program, including regular filter changes, fluid flushes and component inspections, can help mitigate the effects of contamination and ensure optimal pump performance. 90-L-130-MA-1-BC-80-S-3-F1-F-03-GBA-35-35-20 90L130MA1BC80S3F1F03GBA353520 90L130-MA-1-CD-80-L-4-F1-H-03-GBA-35-35-30 90L130MA1CD80L4F1H03GBA353530 90-L-130-MA-1-CD-80-L-4-F1-H-03-GBA-35-35-30 90L130MA1CD80L4F1H03GBA353530 90L130-MA-1-CD-80-P-4-C8-F-03-GBA-26-26-24 90L130MA1CD80P4C8F03GBA262624 90-L-130-MA-1-CD-80-P-4-C8-F-03-GBA-26-26-24 90L130MA1CD80P4C8F03GBA262624 90L130-MA-1-CD-80-R-3-F1-F-03-GBA-42-42-24 90L130MA1CD80R3F1F03GBA424224 90-L-130-MA-1-CD-80-R-3-F1-F-03-GBA-42-42-24 90L130MA1CD80R3F1F03GBA424224 90-L-130-MA-1-CD-80-S-3-F1-F-03-GBA-35-35-20 90L130MA1CD80S3F1F03GBA353520 90-L-130-MA-1-DE-80-P-3-F1-F-09-GBA-45-45-20 90L130MA1DE80P3F1F09GBA454520 90L130-MA-1-NN-80-L-3-F1-F-03-GBA-32-32-24 90L130MA1NN80L3F1F03GBA323224 10. Training and Education: Proper training and education for those responsible for the operation and maintenance of aviation plunger pumps is essential. They should be aware of the importance of contamination control and its effect on pump performance. Training programs can include proper fluid handling procedures, filtration system maintenance, and the importance of regular fluid analysis to maintain desired relative volume flow and minimize wear on friction components. 11. Compliance: Compliance with relevant industry standards and regulations is important to ensure the use of clean and properly maintained hydraulic fluids. Regulatory guidelines may specify cleanliness levels, fluid change intervals, and recommended maintenance practices to prevent contamination-related problems and ensure safe and reliable pump operation. By considering these additional factors and implementing appropriate contamination control measures, regular maintenance practices, and personnel training, the effects of contaminated hydraulic oil on relative volumetric flow and wear on friction components of aviation piston pumps can be effectively controlled. This will help maintain the performance of the pump, prolong its life and minimize the risk of unexpected failure or shutdown.
