Lubricating device for seawater hydraulic pump

Abstract

The invention discloses a lubricating device for a seawater hydraulic pump. The lubricating device comprises a supporting base, a power box body, a bearing lubricating groove and a plunger lubricatinggroove. Mounting holes are formed in four corners of the supporting base, the power box body is arranged above the supporting base, a top sealing cover plate is arranged above the power box body, anda lubricating oil injection pipe is arranged on the top sealing cover plate. The lubricating device has the beneficial effects that by arranging a seal ring and an end part telescopic sealing cover,the power box body and a plunger box body can be separated slidably to prevent seawater from seeping into the power box body to corrode parts in the power box body, so that the service life of the seawater hydraulic pump is prolonged; by arranging a heat-resistant corrosion-resistant coating, the heat-resistant corrosion-resistant performance of a plunger rod can be improved effectively, and the service life of the plunger rod can be prolonged effectively; by arranging a turbine and worm lubricating pipe, the bearing lubricating groove and the plunger lubricating groove, the parts in the powerbox body can be lubricated well, the frictional force is reduced, and the service performance of the seawater hydraulic pump is enhanced.

Description

technical field [0001] The invention relates to the technical field of hydraulic pumps, in particular to a lubricating device for a seawater hydraulic pump. Background technique [0002] With the continuous development of industrial technology, industrial automation has become the mainstream direction of modern industrial development. The development of industrial automation is inseparable from the support of hydraulic transmission technology. Most of the traditional hydraulic transmission equipment uses industrial oil as the carrier, and the pollution is relatively large. At the same time, the cost is relatively high. Seawater hydraulic transmission technology is a new technology developed internationally in recent years to adapt to ocean development. It is an important development direction of hydraulic transmission technology. Because of its good flame resistance, it is especially compatible with marine environments.

[0002] With the continuous development of industrial technology, industrial automation has become the mainstream direction of modern industrial development. The development of industrial automation is inseparable from the support of hydraulic transmission technology. Most of the traditional hydraulic transmission equipment uses industrial oil as the carrier, and the pollution is relatively large. At the same time, the cost is relatively high. Seawater hydraulic transmission technology is a new technology developed internationally in recent years to adapt to ocean development. It is an important development direction of hydraulic transmission technology. Because of its good flame resistance, it is especially compatible with marine environments. Compatibility, no environmental pollution, high efficiency, and more and more people's attention, this is mainly because the application of seawater medium has changed people's traditional concept of sealing and lubrication, seawater has strong corrosion, low viscosity, poor lubrication performance, Due to the characteristics of high vaporization pressure, the seawater hydraulic components developed must have good wear resistance, corrosion resistance, fatigue resistance and cavitation resistance. Seawater hydraulic pumps currently on the market will slow down during use. It slowly penetrates into the power box of the hydraulic pump, and then corrodes the internal parts of the hydraulic pump, reducing the service life of the hydraulic pump. The lubrication inside the power box is not in place, resulting in serious wear of the internal parts of the power box, which affects the performance of the hydraulic pump
