Technical Field

[0001] This utility model relates to a pump body, specifically a pump body structure with high sealing performance. Background Technology

[0002] The sealing performance of the pump body affects the pump's operating efficiency. Currently, a lip seal ring is installed between the shaft sleeve and the pump body, with the lip of the seal ring tightly fitting against the shaft sleeve to create a seal. However, vibration is unavoidable during pump operation, and tiny gaps may form between the lip and the shaft sleeve due to vibration, leading to leakage. Utility Model Content

This invention adds a clamping component to the lip sealing ring, which can clamp the lip of the sealing ring, making it resistant to vibration, improving sealing performance, and preventing leakage.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a pump body structure with high sealing performance, including a pump body and a lip sealing ring, wherein the pump body is provided with a clamping assembly for clamping the lip sealing ring; the clamping assembly includes a clamping rod, a spring, and a mounting plate, wherein the mounting plate is fixed to the outer side of the pump body, one end of the spring is fixed to the mounting plate and extends into a hole in the pump body, and the other end of the spring is fixedly connected to the clamping rod, wherein one end of the clamping rod is in the hole and the other end passes through the through hole of the lip sealing ring and is clamped onto the lip.

[0005] The mounting plate is also fixed with a sleeve, the spring is completely placed inside the sleeve, and one end of the clamping rod is inside the sleeve.

[0006] A retaining ring is provided on the inner wall of the outer end of the sleeve, and a limiting ring is provided at the end of the clamping rod located in the sleeve. The limiting ring is blocked by the retaining ring so that the end of the clamping rod is always located inside the sleeve.

[0007] The through hole is formed in the main body of the lip sealing ring, and the through hole is aligned with the hole.

[0008] The lip has a clamping groove, and the end of the clamping rod extends into the clamping groove.

[0009] The clamping groove is arc-shaped, and the end of the clamping rod is arc-shaped.

[0010] In summary, this utility model achieves the following technical effects:

[0011] The pump shaft is installed in the shaft hole of the pump body of this utility model, and a shaft sleeve is provided. Two lip sealing rings are provided on the outer side of the shaft sleeve. Each sealing ring is equipped with at least four clamping components, which are evenly distributed around the circumference of each sealing ring. Correspondingly, the sealing rings are pre-cut with evenly distributed through holes and clamping grooves for better installation. Attached Figure Description

The pump body 1 is provided with a clamping assembly 4 for clamping the lip sealing ring 3. The clamping assembly 4 includes a clamping rod 41, a spring 44, and a mounting plate 43. The mounting plate 43 is fixed to the outer side of the pump body 1. One end of the spring 44 is fixed to the mounting plate 43 and extends into the hole 13 of the pump body 1. The other end of the spring 44 is fixedly connected to the clamping rod 41. One end of the clamping rod 41 is in the hole 13, and the other end passes through the through hole 32 of the lip sealing ring 3 and is clamped onto the lip.

[0023] This invention adds a clamping component to the lip sealing ring of the pump body, which can clamp the lip of the sealing ring, improve the sealing performance, and prevent leakage.
