According to the vertical and horizontal dual-purpose self-priming centrifugal pump, the detachable water inlet mechanism 1 and the detachable water outlet mechanism 4 are adopted to replace a fixedly connected suction cavity and a discharge cavity of the traditional self-priming centrifugal pump, so that the structure of the pump body 2 is simplified, and the production and processing efficiency is improved; and the main parts of the centrifugal pump provided by the embodiment are universal, and the horizontal centrifugal pump and the vertical centrifugal pump are mutually converted only by replacing different water inlet mechanisms 1 and water outlet mechanisms 4, so that the application range is expanded, and the production cost is reduced.
Preferably, the centrifugal mechanism includes a guide vane 5 and an impeller 6, the guide vane 5 is disposed on one side of the impeller 6 far away from the driving mechanism, and the guide vane 5 and the impeller 6 enclose a centrifugal cavity for conveying liquid.
The impeller 6 rotates at a high speed under the action of the driving mechanism, water entering the centrifugal cavity also starts to rotate at a high speed under the action of the impeller 6, so that centrifugal motion is generated, the water is continuously thrown to the edge of the impeller 6, then leaves the centrifugal cavity through the water outlet channel, enters the water outlet mechanism 4, and flows out of a water outlet of the water outlet mechanism 4.
In the structure, the pump body 2 has universality within a certain range, the pump body 2 can contain impellers 6 and corresponding guide vanes 5 with different outer diameters, and the universal pump body 2 can meet the requirements of different flow lifts only by matching different guide vanes 5 and impellers 6, so that the number of moulds is reduced, the production cost is reduced, and the production efficiency is improved.
As shown in fig. 1 and 2, the impeller 6 preferably includes a vane 61 and a rear pump cover 62, and the rear pump cover 62 is disposed between the vane 61 and the driving mechanism.
As described above, as shown in fig. 7 to 9, the impeller 6 is preferably a semi-open impeller 6 including the blades 61 and the rear pump cover 62, and the semi-open impeller 6 has a wide application range and a high adaptability, and is suitable for conveying clean water or liquid that is similar to clean water and contains suspended solids such as solid particles and fibers; and compared with the closed impeller 6, the semi-open impeller 6 is lower in manufacturing difficulty, so that the production cost is reduced.
Preferably, the driving mechanism comprises a motor 8, and the impeller 6 is sleeved on an output shaft of the motor 8.
At present, a vertical self-priming centrifugal pump and a horizontal self-priming centrifugal pump are respectively provided with a separated motor connection mode and a direct connection motor connection mode, the separated motor connection mode is long in pump set length and needs to occupy more space due to the fact that a bearing seat is arranged in the separated motor connection mode, and although the direct connection type relatively shortens the length of the pump set, the pump shaft is directly sleeved on a motor type output shaft, and maintenance and disassembly are very difficult.
This embodiment adopts no pump shaft structure, with impeller 6 cup joint in on the output shaft of motor 8, solved above-mentioned problem, owing to cancelled the pump shaft, the dismouting is very convenient, and compact structure, and occupation space is few.
Preferably, the pump body 2 is provided with a water inlet and a water outlet, the water inlet is communicated with the water inlet mechanism 1, and the water outlet is communicated with the water outlet mechanism 4.

Because the centrifugal pump mainly transports the liquid through atmospheric pressure, the water inlet mechanism 1 and the water outlet mechanism 4 need to be tightly attached to the pump body 2; the utility model discloses a reach above-mentioned purpose, as shown in fig. 1 and fig. 2, be equipped with the second connecting portion of being connected with the pump body 2 on water inlet mechanism 1 and the mechanism 4 that goes out, the connection face of second connecting portion is the smooth connection face, and is relative, and the connection face of the first connecting portion on the pump body 2 also is the smooth connection face to under the effect of bolt, water inlet mechanism 1 and the mechanism 4 that goes out are hugged closely together with the pump body 2 is tight, the effectual transportation of having guaranteed liquid in the centrifugal pump.
The structure of the connecting part is an optimal structure, and other structures can be adopted, and only the water inlet mechanism 1 and the water outlet mechanism 4 are required to be ensured to be tightly attached to the pump body 2 respectively, for example, the second connecting part can be of a convex structure, and the first connecting part can be of a concave structure, so that the fool-proof effect is achieved, the connecting parts can be connected in a screwed manner conveniently, and the first connecting part and the second connecting part can be tightly attached to each other.

The principle of the self-suction of the centrifugal pump is as follows, as described above, when the liquid enters the centrifugal chamber, the liquid will be thrown from the center of the impeller 6 to the periphery under the action of the centrifugal force, at this time, the inlet of the impeller 6 forms vacuum or low pressure due to the discharge of the liquid, the liquid in the water inlet mechanism 1 is pressed into the centrifugal chamber of the impeller 6 under the action of the atmospheric pressure, and then the rotating impeller 6 continuously sucks and discharges the liquid.
Without the guide vane water inlet pipe 3, it can be found that the water inlet mechanism 1 is not only communicated with the centrifugal cavity, but also communicated with the water outlet mechanism 4, so that self-suction and discharge of liquid are difficult to realize, and therefore, in order to avoid the communication between the water inlet mechanism 1 and the water outlet mechanism 4, the guide vane water inlet pipe 3 needs to be adopted for isolation.
The guide vane water inlet pipe 3 is preferably detachably connected with the guide vane 5 and the pump body 2, can also be fixedly connected to the guide vane 5 or the pump body 2, and can also be integrally connected to the guide vane 5 or the pump body 2.

For example, referring to fig. 1 and 2, if the vertical centrifugal pump needs to be converted into the horizontal centrifugal pump, the pump body 2 needs to be rotated by a certain angle, and the driving mechanism needs to be correspondingly adjusted at the same time.
Still including the pump foot rest 9 that is used for supporting the pump body 2, pump foot rest 9 is used for supporting the pump body 2, guarantees that the centrifugal pump operation, and the pump body 2 can not rock by a wide margin, influences the transportation effect of liquid.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to fall within the scope of the present disclosure.
