Description

TECHNICAL FIELD

[0001] The present application relates to the field of pump devices, in particular, to a high-performance pump. BACKGROUND

[0002] A pump is a machine that transports fluid or pressurizes fluid. It transmits mechanical energy or other external energy to the liquid, so that the liquid energy increases. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solid. A centrifugal pump usually contains a motor and an impeller part, and heat dissipation fins are usually machined on the surface of the pump body to transfer heat generated by the pump body to the air. However, the heat dissipation fins are usually in the form of thin sheets to ensure heat dissipation effect, and are easily deformed and damaged when colliding with the outside. Therefore, to avoid damage to the pump during transportation and installation, an outer shell is usually needed to cover the pump. However, the existing protective shell is usually large in size and cannot be transported and installed together with the pump body. The pump body needs to be removed before installation, which still has the risk of collision.

[0003] Therefore, there is a need for a high-performance pump with a protective shell that is easy to install. SUMMARY

[0004] The summary part of the present application is used to introduce the concept in a simple form, which will be described in detail in the specific embodiment part.

[0037] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0038] Referring to Figures 1-5 The high-performance pump comprises a pump body 100, a heat dissipation fin 101, a cladding shell 102, a fixing buckle 103 and a buckle groove. The pump body 100 comprises an impeller part 105 and a motor part 106, and the motor part 106 is coaxially arranged with the impeller part 105. A wind cylinder 116 is installed on the impeller part 105, and an annular groove 117 is arranged at the end of the wind cylinder 116, and the annular groove 117 is filled with an adhesive layer. An interface for connecting the annular groove 117 is arranged on the impeller part 105, and an annular protrusion inserted into the annular groove is arranged at the interface.

[0039] The upper end of the pump body 100 is provided with a lifting ring 107. The lower end of the pump body 100 has a mounting pad 108. The mounting heat dissipation fins 101 are uniformly arranged on the surface of the pump body 100 and the front side of the pump body 100. The heat dissipation fins 101 on the side of the pump body 100 are arranged in a strip-shaped structure along the impeller axis direction. The heat dissipation fins 101 on the front side of the pump body 100 are uniformly and vertically arranged. The cladding shell 102 is provided with two symmetrical groups, which are used to be mounted on the pump body 100 to form a gap between the pump body 100. The gap forms an air flow space. The two cladding shells 102 are spliced with each other. The cladding shell 102 includes a cylindrical part 109 and a surrounding part 110. The cylindrical part 109 is used to mount the motor part 106 of the pump body 100. The surrounding part 110 is used to mount the impeller part 105 of the pump body 100. The cylindrical part and the surrounding part 110 are separately arranged. The cylindrical part is provided with an edge 111 inserted into the gap of the heat dissipation fin 101. The fixing buckle 103 is arranged on the edge 111, and the buckle groove is arranged on the heat dissipation fin 101. There is a gap for air inflow between the rear end of the cylindrical part and the pump body 100, so as to control the flow along the fin of the heat dissipation fin 101 and the gap between the cladding shell 102 and the pump body 100. A groove is formed at one end of the cylindrical part for embedding the fin of the heat dissipation fin 101 on the impeller part 105. In an embodiment, the edge 111 of the cylindrical part is inserted into the gap of the heat dissipation fin 101 along the axis direction, so that the buckle is embedded into the buckle groove. The thickness of the edge 111 is consistent with the width of the gap of the heat dissipation fin 101, so that the heat dissipation fin 101 positions the cylindrical part. At the same time, through the groove, the heat dissipation fin 101 avoids blocking the cylindrical part, and at the same time, the cylindrical part can be positioned during installation through the heat dissipation fin 101, so as to avoid installation position deviation.

[0040] The surrounding part 110 has a shielding plate 112 for shielding the front end of the impeller part 105 and an arc-shaped plate 113 for covering the side of the impeller part 105. The arc-shaped plate 113 and the shielding plate 112 are integrally arranged. The shielding plate 112 has a notch. The notches on the two shielding plates 112 form a through hole. The cross section of the arc-shaped plate 113 in the horizontal plane is in an arc-shaped structure, which has a short wing piece 114 inserted into the gap of the heat dissipation fin 101 and a wing plate 115 covering the side of the impeller part 105. In an embodiment, the short wing piece 114 is also provided with a buckle. The buckle groove is formed on the impeller part 105. The two surrounding parts 110 clamp the impeller part 105 in the middle and move towards each other. The buckle is embedded into the buckle groove to install the two surrounding parts 110. At the same time, the two shielding plates 112 are spliced with each other. At the same time, the shielding plate 112 has a distance from the pump body 100.

[0041] The end of the enclosure part 110 abuts against the sidewall of the cylindrical part, and the enclosure part 110 is attached to the cylindrical part, so that the airflow can continue to flow to the position of the enclosure part 110 when passing through the cylindrical part. In an embodiment, when the two shielding plates 112 are completely matched, the end of the enclosure part 110 is inserted into the gap provided on the cylindrical part and matched with the gap.
