Lubricating oil pump is mainly used for conveying lubricating oil in the lubrication system of famous mechanical equipment, and it is suitable for conveying lubricating oil with viscosity below 10(75C.ST) and temperature below 80ºC, and is also suitable for conveying corrosive oil.
Non-lubricating medium containing solid particles
Lubricating oil pump is mainly composed of pump body, gear, shaft, bearing, front cover and back cover, sealing parts, coupling and other parts. There are two forms of shaft end seal: packing seal and mechanical seal.
When the meshing gear rotates in the pump body, the gear teeth keep entering and exiting and meshing. In the suction chamber, the gear teeth gradually withdraw from the meshing state, so that the volume of the suction chamber gradually increases and the pressure decreases, and the liquid enters the suction chamber under the action of the liquid level pressure and enters the discharge chamber with the gear teeth. In the discharge chamber, the gear teeth gradually enter the meshing state, and the teeth between gears are gradually occupied by the teeth of a gear. The volume of the discharge chamber decreases, and the pressure of the liquid in the discharge chamber increases, so that the liquid is discharged from the pump outlet, and the gear rotates continuously, and the above process continues to form a continuous oil conveying process.
