The viscosity of the oil used in the hydraulic pump has a major influence on the pressure distribution of the distribution secondary seal. The following details how changes in oil viscosity affect the pressure distribution: 1. Viscosity and pressure distribution: The viscosity of the oil affects the flow resistance within the pump distribution pair. Oils of higher viscosity create greater resistance to flow, resulting in increased pressure loss. As the oil flows through the distribution pair, the pressure drops due to frictional losses. The pressure distribution across the sealing strip is influenced by these pressure losses, which may vary with oil viscosity. 2. Shear rate and viscosity: Oil viscosity is affected by the shear rate in the pump. Shear rate refers to the rate at which adjacent fluid layers move relative to each other. In hydraulic pumps, the shear rate can vary significantly depending on the speed, flow and design of the pump. The oil experiences different shear rates across the distribution pair, and this shear rate affects its viscosity. The viscosity of an oil can change as a function of shear rate, a behavior known as shear thinning or shear thickening. 3. Influence on the performance of the sealing belt: the pressure distribution on the sealing belt has an important effect on its sealing effect and wear characteristics. Variations in oil viscosity can cause uneven pressure distribution on the sealing strip. Higher viscosity oils can result in higher pressure drops, which can lead to increased wear and friction losses. On the other hand, lower viscosity oils may result in reduced pressure drop and potential sealing problems. 90-R-180-MA-1-EF-80-T-C-C8-H-03-NNN-20-20-24 90R180MA1EF80TCC8H03NNN202024 90R180-MA-1-EG-80-S-M-C8-J-02-NNN-42-42-24 90R180MA1EG80SMC8J02NNN424224 90-R-180-MA-1-EG-80-S-M-C8-J-02-NNN-42-42-24 90R180MA1EG80SMC8J02NNN424224 90R180-MA-1-NN-80-S-C-F1-H-03-FAC-42-42-24 90R180MA1NN80SCF1H03FAC424224 90-R-180-MA-1-NN-80-S-C-F1-H-03-FAC-42-42-24 90R180MA1NN80SCF1H03FAC424224 90R180-MA-1-NN-80-S-C-F1-H-03-NNN-35-35-24 90R180MA1NN80SCF1H03NNN353524 90-R-180-MA-1-NN-80-S-C-F1-H-03-NNN-35-35-24 90R180MA1NN80SCF1H03NNN353524 90R180-MA-1-NN-80-S-M-C8-J-03-NNN-38-38-24 90R180MA1NN80SMC8J03NNN383824 90-R-180-MA-1-NN-80-S-M-C8-J-03-NNN-38-38-24 90R180MA1NN80SMC8J03NNN383824 90R180-MA-2-BC-80-S-C-C8-H-02-FAC-38-38-24 90R180MA2BC80SCC8H02FAC383824 90-R-180-MA-2-BC-80-S-C-C8-H-02-FAC-38-38-24 90R180MA2BC80SCC8H02FAC383824 90R180-MA-2-NN-80-S-C-C8-J-03-NNN-20-20-22 90R180MA2NN80SCC8J03NNN202022 90-R-180-MA-2-NN-80-S-C-C8-J-03-NNN-20-20-22 90R180MA2NN80SCC8J03NNN202022 90R180-MA-2-NN-80-S-C-C8-J-03-NNN-42-42-24 90R180MA2NN80SCC8J03NNN424224 90-R-180-MA-2-NN-80-S-C-C8-J-03-NNN-42-42-24 90R180MA2NN80SCC8J03NNN424224 90R180-MA-5-AB-80-S-C-C8-J-C5-FAC-42-42-24 90R180MA5AB80SCC8JC5FAC424224 90-R-180-MA-5-AB-80-S-C-C8-J-C5-FAC-42-42-24 90R180MA5AB80SCC8JC5FAC424224 90R180-MA-5-AB-80-S-M-C8-H-C5-FAC-32-32-24 90R180MA5AB80SMC8HC5FAC323224 90-R-180-MA-5-AB-80-S-M-C8-H-C5-FAC-32-32-24 90R180MA5AB80SMC8HC5FAC323224 90R180-MA-5-AB-80-S-M-C8-J-C5-NNN-23-23-24 90R180MA5AB80SMC8JC5NNN232324 4. Leakage and efficiency: The pressure distribution on the sealing belt affects the leakage of oil from the high pressure side to the low pressure side of the pump. Inconsistent pressure distribution due to changes in oil viscosity can cause uneven seals, leading to increased leakage and reduced pump efficiency. Optimal pressure distribution is critical to effective sealing, reducing friction and improving overall pump performance. 5. Effect of temperature: The viscosity of oil is also related to temperature. Oils tend to decrease in viscosity as temperature increases, while lower temperatures cause viscosity to increase. Changes in oil viscosity due to temperature changes further affect the pressure distribution on the sealing strip. It is important to consider the operating temperature range of the pump and the corresponding viscosity characteristics of the oil to ensure proper sealing performance. 6. Risk of cavitation: The viscosity of the oil plays an important role in preventing cavitation in the pump. Cavitation occurs when the pressure drops to the point where the oil evaporates, causing air bubbles to form. These air bubbles can damage sealing surfaces and reduce pump efficiency. Changes in oil viscosity can affect the occurrence of cavitation by affecting the pressure distribution on the sealing strip. Higher viscosity oils tend to have better cavitation resistance than lower viscosity oils. 90-R-180-MA-5-AB-80-S-M-C8-J-C5-NNN-23-23-24 90R180MA5AB80SMC8JC5NNN232324 90R180-MA-5-AB-80-S-M-F1-H-C5-FAC-32-14-30 90R180MA5AB80SMF1HC5FAC321430 90-R-180-MA-5-AB-80-S-M-F1-H-C5-FAC-32-14-30 90R180MA5AB80SMF1HC5FAC321430 90R180-MA-5-AB-80-T-C-C8-J-C5-FAC-38-38-24 90R180MA5AB80TCC8JC5FAC383824 90-R-180-MA-5-AB-80-T-C-C8-J-C5-FAC-38-38-24 90R180MA5AB80TCC8JC5FAC383824 90R180-MA-5-AB-80-T-C-C8-J-C5-NNN-42-42-24 90R180MA5AB80TCC8JC5NNN424224 90-R-180-MA-5-AB-80-T-C-C8-J-C5-NNN-42-42-24 90R180MA5AB80TCC8JC5NNN424224 90R180-MA-5-AB-80-T-C-F1-H-C5-NNN-20-20-24 90R180MA5AB80TCF1HC5NNN202024 90-R-180-MA-5-AB-80-T-C-F1-H-C5-NNN-20-20-24 90R180MA5AB80TCF1HC5NNN202024 90R180-MA-5-BC-80-S-C-C8-H-C6-NNN-42-42-24 90R180MA5BC80SCC8HC6NNN424224 90-R-180-MA-5-BC-80-S-C-C8-H-C6-NNN-42-42-24 90R180MA5BC80SCC8HC6NNN424224 90R180-MA-5-BC-80-S-C-C8-H-C6-NNN-45-45-28 90R180MA5BC80SCC8HC6NNN454528 90-R-180-MA-5-BC-80-S-C-C8-H-C6-NNN-45-45-28 90R180MA5BC80SCC8HC6NNN454528 90R180-MA-5-BC-80-S-C-C8-J-C5-NNN-35-35-24 90R180MA5BC80SCC8JC5NNN353524 90-R-180-MA-5-BC-80-S-C-C8-J-C5-NNN-35-35-24 90R180MA5BC80SCC8JC5NNN353524 90R180-MA-5-BC-80-S-M-C8-J-C5-NNN-42-42-24 90R180MA5BC80SMC8JC5NNN424224 90-R-180-MA-5-BC-80-S-M-C8-J-C5-NNN-42-42-24 90R180MA5BC80SMC8JC5NNN424224 90R180-MA-5-BC-80-T-C-C8-J-C6-NNN-45-45-28 90R180MA5BC80TCC8JC6NNN454528 90-R-180-MA-5-BC-80-T-C-C8-J-C6-NNN-45-45-28 90R180MA5BC80TCC8JC6NNN454528 90R180-MA-5-BC-80-T-M-C8-H-C5-NNN-26-26-24 90R180MA5BC80TMC8HC5NNN262624 7. Lubrication and oil film thickness: The viscosity of the oil is directly related to the lubricating performance between the sealing surfaces and the thickness of the oil film. Adequate oil film thickness is critical to provide proper lubrication and prevent metal-to-metal contact, which can lead to wear and damage. Changes in oil viscosity affect the oil film thickness and thus the pressure distribution on the sealing strip. Optimum oil viscosity selection ensures an adequate oil film to maintain an effective seal and minimize wear. 8. Temperature and Viscosity Control: Controlling the temperature of the hydraulic system is critical to maintaining consistent oil viscosity as well as pressure distribution in the seal band. Excessive temperature changes can cause significant changes in oil viscosity, affecting sealing performance and pressure distribution. Temperature control measures such as cooling systems or proper heat dissipation can help stabilize oil viscosity and maintain a consistent pressure distribution. 9. Oil Selection and Maintenance: Selecting the proper oil viscosity for a hydraulic pump application is critical to achieving optimal sealing and pressure distribution. Manufacturers often provide guidelines and recommendations regarding the appropriate viscosity range for their pumps. Regular oil analysis and maintenance procedures such as oil filtration and replacement are necessary to ensure viscosity remains within the desired range and to prevent contamination or degradation that could affect pressure distribution. 90-R-180-MA-5-BC-80-T-M-C8-H-C5-NNN-26-26-24 90R180MA5BC80TMC8HC5NNN262624 90R180-MA-5-BC-80-T-M-C8-H-C5-NNN-35-35-24 90R180MA5BC80TMC8HC5NNN353524 90-R-180-MA-5-BC-80-T-M-C8-H-C5-NNN-35-35-24 90R180MA5BC80TMC8HC5NNN353524 90R180-MA-5-CD-80-D-M-C8-L-C5-NNN-35-35-24 90R180MA5CD80DMC8LC5NNN353524 90-R-180-MA-5-CD-80-D-M-C8-L-C5-NNN-35-35-24 90R180MA5CD80DMC8LC5NNN353524 90R180-MA-5-CD-80-S-C-C8-H-C5-NNN-29-29-24 90R180MA5CD80SCC8HC5NNN292924 90-R-180-MA-5-CD-80-S-C-C8-H-C5-NNN-29-29-24 90R180MA5CD80SCC8HC5NNN292924 90R180-MA-5-CD-80-S-C-C8-H-C5-NNN-32-32-24 90R180MA5CD80SCC8HC5NNN323224 90-R-180-MA-5-CD-80-S-C-C8-H-C5-NNN-32-32-24 90R180MA5CD80SCC8HC5NNN323224 90R180-MA-5-CD-80-S-M-C8-J-C5-NNN-35-35-24 90R180MA5CD80SMC8JC5NNN353524 90-R-180-MA-5-CD-80-S-M-C8-J-C5-NNN-35-35-24 90R180MA5CD80SMC8JC5NNN353524 90R180-MA-5-CD-80-T-C-C8-J-C6-NNN-45-45-28 90R180MA5CD80TCC8JC6NNN454528 90-R-180-MA-5-CD-80-T-C-C8-J-C6-NNN-45-45-28 90R180MA5CD80TCC8JC6NNN454528 90R180-MA-5-CD-80-T-M-C8-H-C6-NNN-29-29-24 90R180MA5CD80TMC8HC6NNN292924 90-R-180-MA-5-CD-80-T-M-C8-H-C6-NNN-29-29-24 90R180MA5CD80TMC8HC6NNN292924 90R180-MA-5-CD-80-T-M-C8-J-C5-NNN-26-26-24 90R180MA5CD80TMC8JC5NNN262624 90-R-180-MA-5-CD-80-T-M-C8-J-C5-NNN-26-26-24 90R180MA5CD80TMC8JC5NNN262624 90R180-MA-5-CD-80-T-M-C8-J-C6-NNN-29-29-24 90R180MA5CD80TMC8JC6NNN292924 90-R-180-MA-5-CD-80-T-M-C8-J-C6-NNN-29-29-24 90R180MA5CD80TMC8JC6NNN292924 90R180-MA-5-DE-80-T-C-C8-J-C5-FAC-35-35-24 90R180MA5DE80TCC8JC5FAC353524 10. Design optimization: understanding the influence of oil viscosity changes on pressure distribution can guide the design optimization of distribution auxiliary sealing belts. This may involve consideration of factors such as the size and shape of sealing surfaces, clearances and flow path design to ensure more even pressure distribution. Computational fluid dynamics (CFD) simulations can help evaluate different design configurations and their effect on pressure distribution at different oil viscosities. By considering the effect of oil viscosity changes on the pressure distribution of hydraulic pump distribution pair seals and taking appropriate measures, manufacturers can optimize pump performance, reduce wear and improve overall efficiency. It is important to select the proper oil viscosity for specific operating conditions, control temperature fluctuations and maintain the oil regularly to ensure consistent and proper pressure distribution across the entire sealing zone.
