Description

Technical Field

[0001] The utility model belongs to the field of water pumps, and relates to a water pump, in particular to a water pump with stable operation. Background Art

[0002] A water pump is a machine for transporting liquids or increasing the pressure of liquids. Before starting the water pump, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed. The water undergoes a centrifugal motion, is thrown to the outer edge of the impeller, and flows into the pressure water pipe of the water pump through the flow channel of the volute pump casing.

[0003] However, in the existing technology, when the existing water flow passes through the pump body and is driven by the impeller to rotate at a high speed, the water pressure impact is relatively large. Therefore, water seepage occurs at the connection between the water outlet of the water pump and the pipeline, and the connection structure becomes loose, seriously affecting the working efficiency of the water pump. Summary of the Invention

[0004] The purpose of the utility model is to provide a water pump with stable operation to solve the above problems for the problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A water pump with stable operation includes a driving motor and a pump body. An outlet joint for facilitating pipeline connection is arranged on the pump body. It is characterized in that the outlet joint is communicated with the inside of the pump body, and a slow-down mechanism for slowing down the water flow velocity is arranged inside the outlet joint.

[0006] The slow-down mechanism includes a plurality of flow guiding slow-down plates, a slow-down sleeve for slowing down the water flow velocity, and a slow-down member movably connected inside the slow-down sleeve.

[0007] A plurality of the slow-down plates are arranged at intervals in the circumferential direction along the inner peripheral wall of the outlet joint, and the slow-down plates, the slow-down sleeve and the outlet joint are integrally formed.

[0008] A plurality of the slow-down plates are arranged in a spiral sheet structure inside the outlet joint.

[0009] A guiding flow channel for slowing down the water flow velocity is formed between two adjacent slow-down sheets, and the guiding flow channel is arranged in a vortex structure.

[0010] In the above water pump with stable operation, the slow-down member is transversely arranged inside the slow-down sleeve. The slow-down member includes a plurality of flow blocking plates, a connecting shaft and a rotating sleeve. The rotating sleeve is movably sleeved on the connecting shaft. Among them, both ends of the connecting shaft are movably connected to the inner wall of the slow-down sleeve.

[0011] In the above-mentioned water pump with stable operation, several of the baffle plates are fixedly connected to the rotating sleeve and are arranged at intervals in a circumferential direction along the outer peripheral wall of the rotating sleeve. The impact of the water flow on the baffle plates causes the rotating sleeve to rotate, driving the baffle plates to rotate.

[0012] In the above-mentioned water pump with stable operation, the corresponding ends of the flow-slowing plates are arranged in an inclined structure to facilitate the separation and slowdown of the water flow.

[0013] Compared with the prior art, the water pump with stable operation has a simple structural design, which can fully buffer the water flow, form a slow-flowing effect, reduce the impact intensity on the pipe connection, and thus reduce the occurrence of water seepage problems.
