Hydraulic media used in hydraulic pumps are susceptible to contamination from various sources such as dust, dirt and moisture. Over time, the buildup of contaminants can lead to reduced efficiency and performance of hydraulic systems and, in extreme cases, damage to pumps and other components. There are several methods for detecting the degree of contamination of hydraulic media: Visual inspection: This involves physically inspecting the hydraulic fluid for any signs of contamination such as discoloration, cloudiness, or the presence of debris or deposits. Particle counting: This involves measuring the number and size of particles in hydraulic fluid using specialized equipment. Particle counters can provide information on particle size and concentration, which can be used to assess contamination levels. Spectroscopic Analysis: This involves analyzing the chemical composition of the hydraulic fluid using a spectrometer. Spectral analysis can provide information about the presence of contaminants such as water, metal particles or other substances. Acid Value Test: This involves measuring the acidity of the hydraulic oil using a test kit. High acidity indicates the presence of contaminants, such as water or other acidic substances. Viscosity testing: This involves measuring the viscosity of the hydraulic fluid using a viscometer. Changes in viscosity can indicate the presence of contaminants such as water or other substances that may affect the fluid's flow characteristics. 90-L-075-KT-1-NN-80-S-3-S1-E-00-GBA-32-32-28 90L075KT1NN80S3S1E00GBA323228 90-L-075-KT-2-BB-80-P-4-S1-D-03-GBA-35-35-24 90L075KT2BB80P4S1D03GBA353524 90-L-075-KT-2-NN-60-R-3-S1-E-00-FAC-45-45-24 90L075KT2NN60R3S1E00FAC454524 90-L-075-MA-1-AB-60-L-3-C6-D-03-GBA-42-42-24 90L075MA1AB60L3C6D03GBA424224 90-L-075-MA-1-AB-60-L-3-C7-D-03-GBA-32-32-20 90L075MA1AB60L3C7D03GBA323220 90-L-075-MA-1-AB-60-P-3-C6-D-03-GBA-42-42-20 90L075MA1AB60P3C6D03GBA424220 90-L-075-MA-1-AB-60-P-3-S1-D-03-GBA-29-29-24 90L075MA1AB60P3S1D03GBA292924 90-L-075-MA-1-AB-60-P-3-S1-D-03-GBA-38-38-20 90L075MA1AB60P3S1D03GBA383820 90-L-075-MA-1-AB-60-R-3-T1-E-03-GBA-26-26-24 90L075MA1AB60R3T1E03GBA262624 90-L-075-MA-1-AB-60-S-3-C6-D-03-GBA-35-35-24 90L075MA1AB60S3C6D03GBA353524 By regularly monitoring and testing hydraulic fluids, contamination issues can be detected and addressed before they cause significant damage to hydraulic pumps and other components. Proper maintenance, including regular fluid changes and filter changes, also helps to minimize the risk of contamination and extend the life of your hydraulic system. It is worth noting that the level of contamination allowed in hydraulic fluid will depend on the specific requirements of the hydraulic system and the type of hydraulic pump used. For example, some systems may require a higher degree of cleanliness than others, such as those used in the aerospace or medical industries, where even a small amount of contamination can have serious consequences. In general, it is recommended to follow the manufacturer's guidelines for maintaining hydraulic fluid in hydraulic pumps. This may involve regular fluid analysis, filter changes and other maintenance procedures to ensure the hydraulic system is operating at peak efficiency and performance. In addition to monitoring and maintaining hydraulic fluid, it is also important to minimize the entry of contaminants into the system. This can be achieved by handling and storing hydraulic fluid properly, ensuring all components are properly sealed and protected, and using a proper filtration system to remove contaminants from the hydraulic fluid. In general, detecting and managing the pollution degree of hydraulic media is an important link to maintain the performance and life of hydraulic pumps, and attention should be paid to ensure the safe and efficient operation of hydraulic systems. 90-L-075-KT-1-NN-80-S-3-S1-E-00-GBA-32-32-28 90L075KT1NN80S3S1E00GBA323228 90-L-075-KT-2-BB-80-P-4-S1-D-03-GBA-35-35-24 90L075KT2BB80P4S1D03GBA353524 90-L-075-KT-2-NN-60-R-3-S1-E-00-FAC-45-45-24 90L075KT2NN60R3S1E00FAC454524 90-L-075-MA-1-AB-60-L-3-C6-D-03-GBA-42-42-24 90L075MA1AB60L3C6D03GBA424224 90-L-075-MA-1-AB-60-L-3-C7-D-03-GBA-32-32-20 90L075MA1AB60L3C7D03GBA323220 90-L-075-MA-1-AB-60-P-3-C6-D-03-GBA-42-42-20 90L075MA1AB60P3C6D03GBA424220 90-L-075-MA-1-AB-60-P-3-S1-D-03-GBA-29-29-24 90L075MA1AB60P3S1D03GBA292924 90-L-075-MA-1-AB-60-P-3-S1-D-03-GBA-38-38-20 90L075MA1AB60P3S1D03GBA383820 90-L-075-MA-1-AB-60-R-3-T1-E-03-GBA-26-26-24 90L075MA1AB60R3T1E03GBA262624 90-L-075-MA-1-AB-60-S-3-C6-D-03-GBA-35-35-24 90L075MA1AB60S3C6D03GBA353524 In addition to the aforementioned methods, there are online monitoring systems that continuously monitor the degree of contamination in hydraulic oil. These systems use sensors and other devices to detect and measure contaminant levels and can provide real-time data on fluid conditions. This is especially useful in applications where downtime must be minimized, as it allows early detection of contamination issues before they cause significant damage to the hydraulic system. Another important aspect of monitoring hydraulic media contamination levels is knowing the source of the contamination. Contaminants can enter a hydraulic system from a variety of sources, such as air intakes, external leaks, or wear and tear on internal components. By identifying and addressing sources of contamination, you can reduce the risk of contamination and improve the overall reliability and performance of your hydraulic system. Regular maintenance, including fluid changes and filter changes, is also important to keep your hydraulic system free from contamination. This helps remove any built-up contaminants and ensures the hydraulic system operates at optimum efficiency. Additionally, it is important to use high-quality hydraulic fluid and filters and follow the manufacturer's recommended maintenance schedule to ensure the hydraulic system is properly maintained and free from contamination. In summary, detecting and managing the contamination level of hydraulic media is an important aspect of maintaining the reliability and performance of hydraulic pumps. By using a combination of monitoring and maintenance procedures, you can reduce the risk of contamination and ensure safe and efficient operation of your hydraulic system.
