Description

Horizontal water pump

Technical Field

The utility model relates to a horizontal water pump.

Background

The centrifugal pump is designed according to the centrifugal force principle, and the motor drives the impeller blades rotating at high speed to drive water to rotate, so that the water is thrown out, and the purpose of conveying is achieved. And the motor part on the centrifugal pump needs to be sealed and isolated from the water flow area of the impeller to prevent liquid from entering the motor part, and the traditional sealing effect is not ideal.

Disclosure of Invention

An object of the utility model is to provide a sealed effectual, the infiltration can not appear and get into the inside horizontal water pump of motor.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a horizontal water pump, includes motor, pivot, connection end cover, impeller and outer end cover, the pivot is rotated and is connected on the motor, and impeller fixed connection is served in one of pivot, and outer end cover fixed connection is in connecting the end cover outer end, and is equipped with water inlet and delivery port on the outer end cover, still includes gland and sealing washer, the outside of connecting the end cover is equipped with the annular seal groove, and the gland suit is in the pivot, and in the flange limit on outer edge stretched into the annular seal groove, set up the sealing washer on the flange limit, the outer lane pressure of outer end cover was on the sealing washer to with be connected end cover fixed connection.

The impeller has three, and all is covered with the impeller wheel cover on every impeller, and the periphery of the most inboard impeller wheel cover is equipped with a plurality of radial hole, fixedly connected with guide fin on the gland.

The rear end fixedly connected with rear end housing of motor, the other end tip fixedly connected with fan of pivot.

The outer edge of the connecting end cover is provided with an annular opening, and the outer ring of the outer end cover is provided with an annular flange matched with the annular opening.

After the structure of the oil pipe is adopted, the utility model discloses because the flange limit on the outer edge of gland stretches into in the annular seal groove to set up the sealing washer, press on the sealing washer with the outer lane of end cover again, play sealed function. Seal with this structure, can improve sealed effect, inside avoiding the infiltration to get into the motor, improve the life of motor.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

Referring to fig. 1 and 2, a horizontal water pump includes a motor 1, a rotating shaft 2, a connecting end cover 3, an impeller 4, and an outer end cover 5, the rotating shaft 2 is rotatably connected to the motor 1, the impeller 4 is fixedly connected to one end of the rotating shaft 2, the outer end cover 5 is fixedly connected to the outer end of the connecting end cover 3, and the outer end cover 5 is provided with a water inlet 51 and a water outlet 52, and further includes a gland 6 and a sealing ring 7, the outer side of the connecting end cover 3 is provided with an annular sealing groove 31, the gland 6 is sleeved on the rotating shaft 2, a flange edge 61 on the outer edge extends into the annular sealing groove 31, the flange edge 61 is provided with the sealing ring 7, and the outer ring of the outer end cover 5 is pressed on the sealing ring.

Referring to fig. 3, the number of the impellers 4 is three, each impeller 4 is covered with an impeller cover 8, the innermost impeller cover 8 is fixedly connected to the gland 6, the outer impeller cover 8 is fixedly connected to the corresponding adjacent impeller cover 8, each impeller cover 8 is provided with a hole, the periphery of the innermost impeller cover 8 is provided with a plurality of radial holes 81, and the gland 6 is fixedly connected with guide fins 9. After entering, the liquid in the water inlet 51 passes through the three impeller covers 8 in sequence to form acceleration and then is thrown out, so that the water flow passing efficiency can be improved.

Referring to fig. 1, a rear end cover 11 is fixedly connected to a rear end of the motor 1, and a fan 10 is fixedly connected to an end of the other end of the rotating shaft 2. During the rotation of the rotating shaft 2, the fan 10 can be driven to rotate, thereby cooling the motor 1.

Referring to fig. 2, the outer edge of the connecting end cap 3 is provided with an annular gap 32, and the outer ring of the outer end cap 5 is provided with an annular flange 53 which is matched with the annular gap 32. The integral connecting part is not protruded, the attractiveness is improved, and the mounting efficiency can be improved in the assembling process.

Referring to fig. 1, 2 shows, the utility model discloses during the use, motor 1 drives pivot 2 and rotates, forms from type force, and liquid gets into from water inlet 51, loops through three impeller shroud 8 and forms the acceleration, and radial hole 81 of rethread flows out, because liquid is rotatory, consequently fixedly connected with guide fin 9 on gland 6 of delivery port 52 department, guide fin 9 blocks rivers, makes rivers flow from delivery port 52 department. The utility model discloses because the flange limit 61 on the outer edge of gland 6 stretches into in the ring seal groove 31, set up sealing washer 7 on the flange limit 61, the outer lane pressure of outer end cover 5 is on sealing washer 7 to with 3 fixed connection of connection end cover. Therefore, the sealing structure can improve the sealing effect of the motor 1, and water cannot seep into the motor 1, so that the service life of the motor 1 is influenced.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
