Hydraulic gear oil pump trapped oil noise and noise reduction strategy

Hydraulic gear oil pump trapped oil noise and noise reduction strategy

In recent years, mute has been an important technical indicator of hydraulic gear oil pumps, however, because the gear oil pump flow and pressure pulsation is its inherent characteristics, the reasons for the noise is more complex, only from the theoretical analysis is often difficult to find the reasons for the noise, must be produced for the different circumstances of the noise, to take different methods and measures in order to reduce the noise in order to be useful.

Research on bearing lubrication method of triplex gear oil pumps

Research on bearing lubrication method of triplex gear oil pumps

In general, the bearing lubrication method is selected correctly or not to determine the conditions of use and life of the triplex gear oil pump bearing, so this is also quite an important part of the gear pump design. Currently three gear oil pump lubrication methods are as follows: the use of high-pressure oil leakage lubrication;

What is the purpose of a bearing on a hydraulic gear pump?

What is the purpose of a bearing on a hydraulic gear pump?

At present, the hydraulic gear pump widely used needle roller bearings have many advantages: high bearing capacity; friction factor is small, start and work with less friction, mechanical efficiency is quite high; can be applied to both high and low speed; can be applied to a wide range of temperatures; anti-oil contamination ability is very strong.
