Description

Technical Field

[0001] The utility model relates to the technical field of water pump impellers, in particular to a water pump impeller with a guide body. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid. The water pump impeller is made of cast iron. The blades on the water pump impeller play a major role. The shape and size of the water pump impeller are closely related to the performance of the water pump. Water pump impellers can generally be divided into single-suction and double-suction types. Single-suction impellers absorb water on one side, and small-flow water pump impellers are mostly of this type. Double-suction impellers absorb water on both sides, and large-flow water pump impellers all use double-suction impellers. At present, water pumps on the market are usually installed with a flow guide structure to ensure the smoothness of the streamline at the overall inlet position of the impeller and ensure the high-efficiency operation of the water pump.

[0003] Current water pump impellers generally include a mounting plate, a shaft sleeve, and blades. The blades in the impeller are easily damaged by the impact of impurities such as particles in the liquid after long-term use. The current blades are integrated and not easy to replace. They can only be replaced as a whole, which increases the cost. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 5 A water pump impeller with a guide body, comprising a sleeve 2 arranged at the top of a mounting plate 1, and a guide body 4 arranged above the sleeve 2; an annular plate 5 is arranged on the surface of the sleeve 2, and blades 3 are arranged on the surface of the annular plate 5 in an annular manner and at equal intervals, and a positioning plate 6 for fixing the blades 3 is connected to the top of the annular plate 5; a connecting groove 301 is opened at the top of the blade 3, and a threaded groove 302 is opened at the bottom end of the inner part of the connecting groove 301; mounting grooves 501 are opened at an annular manner and at equal intervals on the surface of the annular plate 5, and a through hole 502 is opened at the inner top end of the mounting groove 501; racks 601 are arranged on the inner wall of the positioning plate 6 in an annular manner and at equal intervals, and the surface of the rack 601 meshes with the inner surface of the rack 601. It is connected to a gear 602, a screw 603 is fixedly connected to the surface of the gear 602, and a threaded tube 604 is connected to the top of the screw 603, and a connecting plate 605 is connected to the surface of the threaded tube 604. When the blade 3 needs to be replaced, the rack 601 can be moved on the surface of the gear 602 by rotating the positioning plate 6, so that the gear 602 drives the screw 603 to rotate on the surface of the slider. At the same time, when the screw 603 rotates, it can be rotated out from the inside of the threaded groove 302, so that the blade 3 can be removed from the inside of the mounting groove 501, so that the blade 3 can be replaced. The annular plate 5 can be connected to the surface of the mounting disk 1 by bolts or other connecting methods.

[0030] Furthermore, a slide groove is provided at the inner bottom end of the positioning plate 6 , and a slider is slidably connected inside the slide groove and is rotatably connected to the bottom end of the screw rod 603 . The slider and the slide groove facilitate the rotation and movement of the screw rod 603 .

[0031] Furthermore, the diameter of the threaded tube 604 is the same as the inner diameter of the connecting groove 301, and the inner diameter of the threaded tube 604 is the same as the diameter of the threaded groove 302. This makes it convenient to limit the blade 3 after connecting the threaded tube 604 to the connecting groove 301, so as to prevent the blade 3 from moving during the subsequent fixing process and affecting the connection between the screw 603 and the threaded groove 302.

[0032] Furthermore, the vertical cross-sectional area of ​​the blade 3 is the same as that of the mounting groove 501, and the blade 3 is in contact with the inside of the mounting groove 501, which is convenient for avoiding a large gap between the blade 3 and shaking after the blade 3 is installed in the mounting groove 501, thereby preventing the blade 3 from shaking and affecting the normal operation of the blade 3.

[0033] Furthermore, the through hole 502 is located directly above the connecting groove 301 , so that after the blade 3 is brought into contact with the mounting groove 501 , the connecting groove 301 on the blade 3 can be located directly below the through hole 502 , so that the threaded tube 604 can pass through the through hole 502 and contact the inside of the connecting groove 301 .

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
