SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a small in size, simple to operate's water pump structure to it occupies the needs to reduce water pump volume and space, and reduces the installation degree of difficulty.

Water pump structure, including pipy casing, the pipe connection spare of being connected with liquid conveying pipeline is installed respectively at the both ends of casing, installs the dive motor of rotatable impeller and output power in the casing, the dive motor passes through the transmission shaft with the impeller and is connected, the impeller sets up the output that sets up in the export one end of casing output liquid and impeller outwards, leaves the clearance that supplies the liquid circulation between dive motor and the shells inner wall, the one end of the cable of transmission power is passed casing or pipe connection spare and is connected with the dive motor.

The water pump structure of the utility model is characterized in that the pipeline connecting pieces at the two ends of the shell are arranged in the liquid output pipeline, the submersible motor and the impeller are both arranged in the shell, one end of the cable is connected with the power supply, the other end of the cable passes through the shell or the pipeline connecting piece to be connected with the submersible motor, and provides electric power for the submersible motor, and the submersible motor drives the impeller to rotate through the transmission shaft; the liquid is input into the shell from the pipeline through the pipeline connecting piece, then flows to the impeller along the inside of the shell and through the submersible motor, and the rotating impeller can improve the flowing speed of the liquid to form pressurization. The motor of the water pump structure adopts a submersible motor and is arranged in the shell together with the impeller, so that the structure volume can be greatly reduced; when the water pump is installed, only the pipeline connecting piece is connected with the pipeline, and the operation is extremely simple, convenient and quick; the shell and the pipeline connecting pieces at the two ends of the shell form the external shape of the water pump, the shape and the size of the shell are very close to those of the pipeline, the attractiveness of equipment can be greatly improved, the setting requirement of a base in the traditional water pump is reduced, the space occupation requirement is greatly reduced, the installation requirement on the environment is lowered, and therefore the space arrangement convenience in various equipment and environments is improved.

Detailed Description

The utility model provides a water pump structure, including pipy casing 1, the pipe connection spare of being connected with liquid conveying pipeline is installed respectively at the both ends of casing, install the dive motor 4 of rotatable impeller 3 and output power in the casing, the dive motor passes through transmission shaft 5 with the impeller and is connected, the impeller sets up the output that sets up in the export one end of casing output liquid and impeller outwards, leave the clearance that supplies the liquid circulation between dive motor and the shells inner wall, the one end of the cable 6 of transmission power is passed casing or pipe connection spare and is connected with the dive motor.

In the water pump structure, the pipeline connecting piece comprises a flange 21 connected with the liquid conveying pipeline and a pump cover 22 provided with a through hole and communicated with the shell and the flange; two ends in the shell 1 are respectively provided with a supporting seat 7, the supporting seat positioned at the inlet end of the shell is connected with the pump cover at the inlet end of the shell, the impeller 3 is arranged on the other supporting seat, the submersible motor 4 is arranged between the two supporting seats, one end of the pump cover positioned at the outlet end of the shell is sleeved on the outer wall of the shell and is provided with a locking hole, and a locking screw 8 penetrates through the locking hole and the shell to be in threaded connection with the supporting seat at the outlet end; the supporting seat 7 is detachably connected with the pump cover 22, the submersible motor 4 and the impeller 3. Through the setting of this structure, can improve the installation steadiness of dive motor and impeller on the one hand to and the structural connection intensity of whole water pump, on the other hand has also greatly improved the convenience of installing and removing of dive motor and impeller. In addition, a filter screen 9 is installed in the pump cover 22 at the inlet end of the housing 1 to filter impurities in the liquid. In addition, the cable 6 passes through the pump cover 22, because the pump cover can be made of plastics or other appropriate materials, which is convenient for opening holes and assembling and disassembling operations; and the cable 6 is provided with a gland 10 through the pump cap 22 to avoid leakage. Similarly, between pump cover and the casing, between pump cover and the supporting seat, between supporting seat and the dive motor, dive motor and transmission shaft are located and stretch out dive motor department, can set up sealing member 11 respectively to improve the leakproofness.

The water pump structure is characterized in that the submersible motor, the impeller, the two supporting seats and the pump cover at the inlet end of the shell are connected, then the submersible motor, the impeller, the two supporting seats and the pump cover are integrally placed in the shell, another pump cover is sleeved at the outlet end of the shell, then the pump cover, the shell and the supporting seats are fixed by using locking screws, so that the water pump is installed, and then flanges at the two ends are connected to a pipeline, so that the operation is very convenient and fast; after that, the cable is plugged in a power supply, the submersible motor works and drives the impeller to rotate through the transmission shaft; the liquid is input into the shell from the pipeline through the pipeline connecting piece, then flows to the impeller along the inside of the shell and through the submersible motor, and the rotating impeller can improve the flowing speed of the liquid to form pressurization.
