Reasons for Oil Leakage of Pump Gear Pump and Its Maintenance Method

The oil leakage of gear pump is a common phenomenon in the whole hydraulic industry, but in summary, there are only two points. The first is the oil leakage inside the gear pump, and the second is the oil leakage of the pump cover or gear pump body. Then, what are the causes of oil leakage of gear pump and its maintenance methods respectively? A&S Hydraulic Co., Ltd. Abel, Ltd after-sales service department, will analyze them one by one.


Oil leakage inside gear pump: Because of long-term high pressure, the connecting bolts of the left and right pump caps and pump bodies are lengthened by tension, resulting in loosening oil leakage; because the hydraulic pump is easy to be affected by many reasons when delivering oil substances, resulting in oil leakage failure of gear pump from time to time, we will analyze the causes of oil leakage in detail below.
The influence of cleanliness of gear pump pipeline system. Because the hydraulic pump contains some hard impurities in the transmission of oil substances, and the whole pipeline and gear pump itself will have some sticky sand, under the action of pressure or falling off. These hard particles not only cause the friction of gear pump to intensify during the high-speed operation of gear pump, but also obtain energy to become a kind of particle with high kinetic energy, which collides with gear pump and gear. Under such a strong impact, the seal ring of the pump is easy to be broken down over time, resulting in oil leakage.
The quality of gear pump parts is not up to standard. Gear pump parts are complex. Because of the operation principle of gear pump and the convenience of maintenance and management, it is doomed that its casing pump body can not be an integral type, so its sealing performance plays a decisive role in the overall performance of gear pump.
