Description

Technical Field

[0001] The utility model relates to the technical field of oil pumps, in particular to an oil pump with increased flow rate. Background Art

[0002] The oil pump is a device that plays a key role in the engine lubrication system. Its main function is to suck the oil out of the oil pan, pressurize it, and continuously deliver it to various parts of the engine that need lubrication, such as the crankshaft, connecting rod, camshaft, etc., to reduce friction and wear between these parts and ensure the normal operation of the engine.

[0003] However, when a traditional oil pump with increased flow rate is working, a large amount of oil flows in the oil pump, which can easily cause the oil pump to vibrate to a certain extent, and the vibration can cause the pipeline to loosen. When the pipeline is affected by large vibrations for a long time, the pipeline will become loose, which will affect the normal delivery of the oil and cause leakage.

[0004] Therefore, it is necessary to provide a new oil pump with increased flow rate to solve the above-mentioned technical problems. Utility Model Content

The outer sides and inner sides of the three protrusions on the two rotors 17 are respectively fixedly installed with bumps 15 and grooves 16. The bumps 15 are adapted to the grooves 16. When the bumps 15 are meshed with the grooves 16, the oil in the grooves 16 can be squeezed out, which has a certain lubrication effect.

[0026] First, the two connecting sleeves 4 are contacted with the oil inlet 6 and the oil outlet 9 in turn, and fixed by the second bolt 12. When the two sealing annular plates 21 enter the oil inlet 6 and the oil outlet 9, the sealing ring 22 can prevent oil leakage. When the first fixing ear 11 is in contact with the fixing seat 3, the staff first presses the pressing block 14 to extend one end of the clamping rod 13 into the clamping seat 24. At this time, the spring 20 resets the pressing block 14 to push it out of the clamping seat 24 and clamp the clamping rod 13 in the clamping seat 24. When it is necessary to disassemble the oil inlet pipe 5 and the oil outlet pipe 8, press the pressing block 14 again to pull it out. When the oil enters the chamber 23 through the oil inlet pipe 5, the rotation of the two rotors 17 quickly transports the oil to the oil outlet pipe 8. Since a small amount of oil can be stored in the groove 16, when the rotor 17 rotates, the protrusion 15 squeezes the oil in the groove 16 out, thereby achieving a certain lubricity and reducing the friction between the rotor and the pump body.
