Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, and in particular to an impeller for an oil pump. Background Technology

[0002] Oil pumps are lightweight and compact pumps. The two end faces of existing impeller discs are prone to wear, which affects the service life of the oil pump impeller. At the same time, the blades are mostly straight blades, that is, the front and rear blade surfaces are straight. Under the same conditions, it is very difficult to increase the oil pump flow rate of the impeller with straight blades unless the oil pump operating current is increased, but this will put an extra workload on the oil pump and affect its service life.

[0003] Existing technology CN204591776U discloses an oil pump impeller, including an impeller disk and a ring of blades disposed near the outer circumference of the impeller disk. The two end faces of the impeller disk are provided with balancing holes and guide grooves, which are paired and arranged. The balancing holes are located within the guide grooves and are through holes penetrating both end faces of the impeller disk. The key feature is that the balancing holes are elliptical holes, with the major axis of the elliptical holes aligned with the radial direction of the impeller disk; the blades are gourd-shaped blades, with both the front and rear surfaces of the blades having gourd-shaped arc surfaces. The impeller disk of this invention is less prone to wear during operation, thus extending its service life; it also has the advantages of increasing oil pump flow rate and reducing oil pump operating current.

[0004] However, in the above structure, when a single blade is damaged, the entire impeller needs to be replaced, resulting in a waste of resources and increased economic costs. Utility Model Content

[0005] The purpose of this invention is to provide an impeller for an oil pump that solves the problem of resource waste and increased economic costs caused by replacing the entire impeller when a single blade is damaged.

[0006] To achieve the above objectives, this utility model provides an impeller for an oil pump, comprising an impeller disk, a mounting disk, an impeller cover, multiple mounting blocks, multiple blades, and a fixing assembly. The impeller disk is provided with multiple mounting grooves, and the multiple mounting blocks are slidably disposed within the mounting grooves. The multiple blades are fixedly connected to the multiple mounting blocks and are respectively located above the multiple mounting blocks. The mounting disk is provided with multiple limiting grooves, and the limiting grooves cooperate with the blades. The mounting disk is disposed above the impeller disk. The impeller cover is fixedly connected to the mounting disk and is located on the outer side wall of the mounting disk. The fixing assembly is sleeved on the outer side wall of the impeller disk.

[0007] The fixing component includes a fixing strap, a plug, and a fixing bolt. One end of the fixing strap is provided with a slot, and the slot is provided with a first through hole. The plug is fixedly connected to the fixing strap and is located at the end of the fixing strap away from the slot. The plug is provided with a second through hole, and the fixing bolt is threaded between the first through hole and the second through hole.

[0008] The impeller disk has three connecting holes, and the mounting plate has mounting holes. The impeller disk and the mounting plate are connected by three fastening bolts to the three connecting holes and the three mounting holes.

[0009] The inner wall of the limiting groove is equipped with a sealing gasket, and the blade is inserted into the sealing gasket.

[0010] The impeller for the oil pump also includes multiple protection mechanisms, which are respectively disposed on the outer side wall of the multiple blades.

[0011] The protection mechanism includes a mounting strip, two protective plates, and screws. The mounting strip is installed on the outer wall of the blade. The two protective plates are fixedly connected to the mounting strip and are located on both sides of the blade. The screws are threaded between the two protective plates and the blade.

[0012] This utility model discloses an impeller for an oil pump. During installation, multiple mounting blocks are inserted into multiple mounting slots on the impeller disc to initially fix the blades on the mounting blocks. Then, the limiting slots on the mounting disc are inserted downwards corresponding to the blades, and the blades are further fixed by the limiting slots and the impeller cover. At the same time, the mounting slot opening is sealed by the fixing assembly to further prevent the blades from detaching from the mounting slots during rotation. Each component has a single structure, which facilitates subsequent disassembly, maintenance, and replacement. This solves the problem of resource waste and increased economic costs caused by replacing the entire impeller when a single blade is damaged. Attached Figure Description

Figure 2 This is a structural schematic diagram of the mounting block, blade, mounting groove, and limiting groove of the first embodiment of this utility model. Figure 3 This is a schematic diagram of the structure of the insert, slot, first through hole and second through hole in the first embodiment of this utility model.

[0022] This utility model provides an impeller for an oil pump, including an impeller disc 101, a mounting disc 102, an impeller cover 103, multiple mounting blocks 104, multiple blades 105, and a fixing assembly. The fixing assembly includes a fixing belt 106, an insert block 107, and a fixing bolt 108. The above structure solves the problem that when a single blade 105 is damaged, the entire impeller needs to be replaced, which causes resource waste and increases economic costs.

[0023] In a specific embodiment, the impeller disk 101 is provided with multiple mounting slots 110, and multiple mounting blocks 104 are slidably disposed within the mounting slots 110. Multiple blades 105 are fixedly connected to the mounting blocks 104 and are respectively located above the mounting blocks 104. The mounting plate 102 is provided with multiple limiting slots 111, and the limiting slots 111 cooperate with the blades 105. The mounting plate 102 is disposed above the impeller disk 101. The impeller cover 103 is fixedly connected to the mounting plate 102 and is located on the outer wall of the mounting plate 102. The fixing component is sleeved on the outer wall of the impeller disk 101. During installation, multiple mounting blocks 104 are inserted into the mounting plate 101. Within the multiple mounting slots 110 on the impeller disk 101, the blades 105 on the mounting block 104 are initially fixed via the mounting slots 110. The limiting slots 111 on the mounting disk 102 are then inserted downwards corresponding to the blades 105, and the blades 105 are further fixed via the limiting slots 111 and the impeller cover 103. Simultaneously, the mounting slots 110 are sealed by the fixing components to further prevent the blades 105 from detaching from the mounting slots 110 during rotation. Each component has a single structure, facilitating subsequent disassembly, maintenance, and replacement. This solves the problem of resource waste and increased economic costs caused by replacing the entire impeller when a single blade 105 is damaged.

[0024] The fixing band 106 has a slot 112 at one end, and a first through hole 113 on the slot 112. The insert block 107 is fixedly connected to the fixing band 106 and is located at the end of the fixing band 106 away from the slot 112. The insert block 107 has a second through hole 114. The fastening bolt 109 is threaded between the first through hole 113 and the second through hole 114. When fixing multiple blades 105, the fixing band 106 is wrapped around the impeller disk 101 once, so that the insert block 107 is inserted into the slot 112 at the other end of the fixing band 106. The first through hole 113 and the second through hole 114 are fixed by the fastening bolt 108, thereby fixing the fixing band 106 and preventing the blades 105 from disengaging from the mounting groove 110 of the impeller disk 101 during rotation.

[0026] The inner wall of the limiting groove 111 is equipped with a sealing gasket, and the blade 105 is inserted into the sealing gasket. The sealing gasket is used to seal the gap between the limiting groove 111 and the blade 105 to prevent leakage.

[0027] When using the impeller for an oil pump according to this utility model, during installation, multiple mounting blocks 104 are inserted into multiple mounting slots 110 on the impeller disk 101. The blades 105 on the mounting blocks 104 are initially fixed by the mounting slots 110. The limiting slots 111 on the mounting disk 102 are then inserted downwards corresponding to the blades 105. The blades 105 are further fixed by the limiting slots 111 and the impeller cover 103. The three fastening bolts 109 are rotated to fix the mounting disk 102 and the impeller disk 101. At the same time, the fixing belt is... The insert 107 is inserted into the slot 112 at the other end of the fixing belt 106 by rotating the impeller disk 101 around 106. The first through hole 113 and the second through hole 114 are fixed by the fixing bolt 108, thereby fixing the fixing belt 106 and further preventing the blade 105 from dislodging from the mounting groove 110 during rotation. Each component has a single structure, which facilitates subsequent disassembly, maintenance and replacement. This solves the problem that when a single blade 105 is damaged, the entire impeller needs to be replaced, which causes resource waste and increased economic costs.
