Description

Technical Field

[0001] This utility model belongs to the field of water pump technology and relates to a self-priming stainless steel pump. Background Technology

[0002] A self-priming stainless steel pump is a type of stainless steel centrifugal pump that can automatically pump water or other liquids without needing to fill the suction line with water.

[0003] Chinese patent publication number CN216666005U discloses a self-priming stainless steel magnetic pump, including a pump body, a shock-absorbing support base disposed at the bottom of the pump body, a lifting device disposed at the bottom of the shock-absorbing support base, a base disposed at the bottom of the lifting device, and an anti-rotation component disposed between the base and the shock-absorbing support base. The shock-absorbing support base is used to reduce the vibration caused by the pump body during operation, and the lifting device is used to raise or lower the horizontal height of the pump body.

[0004] As can be seen from the specification and accompanying drawings of the patent, the self-priming stainless steel magnetic pump provided by the patent does not have a sealing component and support structure inside the pump body, which can easily lead to insufficient sealing performance inside the pump body and unstable operation. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems existing in the prior art by providing a self-priming stainless steel pump.

[0006] The objective of this utility model can be achieved through the following technical solution: A self-priming stainless steel pump includes a pump body and a drive motor. One end of the drive motor is fixedly connected to a motor bracket. The pump body includes an outer pump casing, a spray tray, an impeller, and a sealing end cover. The outer pump casing covers the outside of the spray tray, impeller, and sealing end cover. An outlet and an inlet are provided in the outer pump casing. A first bushing and a second bushing are fixedly connected to the outlet and inlet, respectively. A first sealing cover and a second sealing cover are respectively sealed on the first bushing and the second bushing. The impeller is installed inside the spray tray. The spray tray is connected to one end of the sealing end cover. A connecting groove is provided on the motor bracket. A connecting plane is formed on the outer end face of the sealing end cover. The connecting plane extends into the connecting groove. A bushing is formed inside the motor bracket. The outer end face of the sealing end cover extends into the motor bracket, and the bushing fits against the outer end face of the sealing end cover. The outer pump casing is fixedly connected to the motor bracket.

[0007] In the aforementioned self-priming stainless steel pump, one end of the impeller has a convex shaft, which extends into and connects to the inside of the injection tray. A sealing ring is provided inside the injection tray, and the sealing ring is located outside the convex shaft.

[0008] In the aforementioned self-priming stainless steel pump, the lower end of the motor bracket is integrally formed with a fixing foot.

[0009] In the aforementioned self-priming stainless steel pump, the second bushing is connected to the injection tray.

[0010] Compared with the prior art, the self-priming stainless steel pump provided by this utility model has the following beneficial effects: 1. By setting a connecting groove on the motor bracket and forming a connecting plane on the outer end face of the sealing end cover, the connection between the sealing end cover and the motor bracket is more stable, and the bushing fits in close contact with the outer end face of the sealing end cover, and the motor bracket provides support for the sealing end cover; 2. Through the structural arrangement of the first bushing, the second bushing, and the sealing ring, the sealing performance of the pump body of this utility model is effectively improved.

Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1 to 4As shown, this embodiment includes a pump body 1, a drive motor 2, and a motor bracket 3. The motor bracket 3 is fixedly connected to one end of the drive motor 2 near the pump body 1. The pump body 1 includes an outer pump housing 11, a spray tray 12, an impeller 13, and a sealing end cover 14. The outer pump housing 11 covers the outside of the spray tray 12, the impeller 13, and the sealing end cover 14 and is fixedly connected to the motor bracket 3 by bolts. An inlet 112 is provided on the front side of the outer pump housing 11, and an outlet 111 is provided on the upper end of the outer pump housing 11. A first bushing 4 is connected to the inlet 112, and a second bushing 5 is connected to the outlet 111 and the spray tray 12. A first sealing cover 41 and a second sealing cover 51 are respectively sealed to the outer ends of the first bushing 4 and the second bushing 5.

[0018] like Figures 1 to 4 As shown, the impeller 13 is installed inside the spray tray 12, and the spray tray 12 is connected to one end of the sealing end cover 14. A connecting groove 31 is provided on the motor bracket 3, and a connecting plane 141 is formed on the outer end face of the sealing end cover 14. The connecting plane 141 extends into the connecting groove 31. This structure makes the sealing end cover 14 and the motor bracket 3 stably connected. A bushing 32 is formed inside the motor bracket 3. The outer end face of the sealing end cover 14 extends into the motor bracket 3, and the bushing 32 fits against the outer end face of the sealing end cover 14. The bushing 32 provides support for the sealing end cover 14, which improves the structural stability of this embodiment.

[0019] To elaborate further, such as Figure 2 As shown, one end of the impeller 13 has a convex shaft 131. The convex shaft 131 extends into and connects to the inside of the spray tray 12.
