Internal leakage of the oil pump is a common and serious problem in the hydraulic system, especially during the operation of the charge pump, its impact is particularly prominent. Internal leakage will not only significantly reduce the working efficiency of the charge pump, but may also pose a threat to the stability and reliability of the entire hydraulic system.
The definition and causes of internal oil pump leakage
Internal leakage of the oil pump refers to the phenomenon of oil flowing from the high-pressure area to the low-pressure area inside the oil pump. The main causes of this phenomenon include aging, damage or improper installation of seals, as well as wear or design defects of internal parts of the oil pump. Internal leakage will hinder the normal supply of oil, thereby affecting the overall operating efficiency of the hydraulic system.
Impact on charge pump operating efficiency
traffic loss
The most direct consequence of internal leakage in the oil pump is flow loss. The oil in the high-pressure area leaks into the low-pressure area, resulting in a reduction in the actual output flow of the charge pump. This reduction in flow will directly lead to a reduction in the working pressure of the hydraulic system, which cannot meet the system's demand for oil flow, thereby affecting the operating efficiency and overall performance of the equipment.
pressure fluctuations
Internal leakage can also cause instability in the output pressure of the charge pump. Due to leakage, the flow of oil inside the oil pump becomes uneven, causing pressure fluctuations. This fluctuation has a negative impact on the stability of the hydraulic system and may cause other components such as relief valves and reversing valves to act frequently, increasing their wear and failure rates.
power loss
Internal oil pump leaks can also cause power loss. As oil leaks, the oil pump needs to consume more energy to overcome the leakage resistance, resulting in a decrease in oil pump power. For a long time, this not only increases the energy consumption of the oil pump, but also reduces its energy efficiency ratio.
Effect on the stability of hydraulic system
System failure
In the case of severe internal leakage in the oil pump, the hydraulic system may fail completely. When the leakage is too large, the charge pump cannot provide enough oil and pressure to maintain the normal operation of the system, resulting in the equipment being unable to complete scheduled actions and functions. This has a serious impact on production efficiency and product quality.
Component damage
Internal leaks can also cause potential damage to other components in the hydraulic system. Leaking oil can carry impurities and particles that can accelerate component wear and failure. In addition, pressure fluctuations and insufficient flow can affect the sealing performance and material properties of the components and reduce their service life.
Solutions and preventive measures
To address the impact of internal leakage in the oil pump on the operation of the charge pump, the following solutions and preventive measures can be taken:
Regular inspection and maintenance: Carry out regular inspection and maintenance of the oil charge pump to detect and solve internal leakage problems in a timely manner. We should focus on checking the wear of seals, bearings and other wearing parts, and replace damaged parts in time.
Improve sealing performance: Use high-quality seals and make sure they are installed correctly. During the design and manufacturing process, the sealing structure of the oil pump is optimized to improve sealing performance.
Optimized oil pump design: Reduce the risk of internal leakage by optimizing the design of the oil pump. For example, the flow channel design of the oil pump is improved to reduce the flow resistance of the oil inside the oil pump, and the oil pump parts are made of wear-resistant materials to improve its service life and reliability.
