Key words:
Hydraulic gear oil pump trapped oil noise and noise reduction strategy
When the gear oil pump is working, a part of the hydraulic oil is trapped in the closed volume formed by the meshing of two pairs of gears and the suction and pressure oil chambers are not connected. When its capacity decreases from large to small, the trapped hydraulic oil is squeezed, and the pressure and speed increase, which is much higher than the output pressure of the gear oil pump
Key words:
Study on Lubrication Mode of Triple Gear Oil Pump Bearing
At present, there are several lubrication methods for three-gear oil pumps: use high-pressure leakage oil for lubrication; high-pressure lubrication that supplies continuous or pulsed oil to the bearing; high-pressure lubrication that uses the reduction of the trapped oil volume to supply pulsed oil to the bearing

Key words:
What is the use of bearings on hydraulic gear pumps?
At present, the needle roller bearings widely used in hydraulic gear pumps have many advantages: high carrying capacity; low friction factor, low friction during starting and working, and high mechanical efficiency; it can be applied to high and low speeds at the same time; it can be applied to Large temperature range; strong resistance to oil pollution.
Key words:
Design Idea and Practical Application of Hydraulic Gear Oil Pump
The hydraulic gear oil pump has radial force imbalance, and the deformation of the gear shaft is biased towards the low pressure area of the pump body, which may cause scraping and boring phenomenon, and at the same time make the floating of the shaft sleeve worse and reduce the working life of the bearing. The method of increasing the high-pressure drainage groove is used in the design of the side plate to increase the range of the high-pressure oil area of the gear pump.
Key words:
Technical Problems in Application of Triple Gear Oil Pump
Disassembly and disassembly of the triple gear oil pump should be carried out in a clean place. After the removed parts are cleaned with gasoline or diesel, carefully check the grinding state of each part to confirm whether it can continue to be used, and then use the parts that can continue to be used. Place carefully in order.
