Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a pump casing structure. Background Technology

[0002] Pumps, as a common fluid transport device, play an important role in many fields such as petroleum, chemical industry, and water conservancy. As one of the core components of a pump, the structural design of the pump casing directly affects the pump's performance and operating effect.

[0003] The pump casing structure in the existing technology is usually relatively simple, mainly made of metal materials and formed by casting or welding. Although this structure meets the basic operating requirements of the pump to a certain extent, the simple pump casing structure often lacks effective sound insulation measures, resulting in the pump generating a lot of noise during operation. In addition, the strength of the pump body structure is also crucial for high-pressure operating environments.

[0004] Therefore, a pump casing structure is needed to improve the above problems. Utility Model Content

The rear end of the casing has an inlet, a bypass interface, and an outlet arranged sequentially from top to bottom. The outer side of the casing is provided with a sound-insulating shell, and several reinforcing ribs are evenly spaced inside the sound-insulating shell. The inner side of the rear end of the casing has a reinforcing structure located at the center of the inner side and extending outwards. The inner side of the rear end of the casing also has a docking structure for connecting a delivery pipeline.

[0008] As a preferred embodiment of this utility model, the soundproof shell includes a soundproof shell, and the soundproof shell has a soundproof interlayer inside.

[0009] As a preferred embodiment of this utility model, the sound insulation interlayer is made of honeycomb sound-absorbing material.

[0010] As a preferred embodiment of this utility model, the reinforcing structure includes a ring rib surrounding the middle of the end face outside the bypass interface, the ring rib being fixedly connected to the housing, and a plurality of inner end face reinforcing ribs extending to the sides being connected to the side of the ring rib.

[0011] As a preferred embodiment of this utility model, the docking structure includes an upper docking ring fixedly connected to one end of the inlet and a set of pipe docking ends fixedly connected to the inside of the bypass interface, wherein the pipe docking ends are arranged on both sides of the bypass interface.

[0012] As a preferred embodiment of this utility model, the back of the housing is provided with a plurality of mounting holes, which are distributed on the outside of the water outlet and the bypass interface, and the plurality of mounting holes are connected to bypass components by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The overall structure of this utility model is reasonably designed. A sound insulation layer is provided on the outside of the shell and reinforcing ribs are provided at intervals, which increases the strength of the outer shell and the overall sound insulation effect.
