Description

Technical Field

[0001] The present application relates to the technical field of water pumps, and in particular to a vertical water pump. Background Art

[0002] The water pump is mainly composed of a pump casing, an impeller, a pump shaft, a pump base, a drive motor and an interception mesh cover, wherein the drive motor is installed on the pump base, the pump casing and the pump base are assembled together, the impeller is coaxially fixedly connected to the output shaft of the drive motor through the pump shaft, and the impeller rotates in the pump casing, a water inlet is formed between the pump casing and the pump base, a water outlet is opened at one end of the pump casing away from the drive motor, and the interception mesh cover is installed on the pump base; when in use, the impeller is driven to rotate by rotating the output shaft of the drive motor, and centrifugal force is generated when the impeller rotates, thereby sucking water into the pump casing along the water inlet and discharged from the water outlet. During the water absorption process, the water inlet is intercepted by the interception mesh cover to prevent larger foreign objects from entering the pump casing and affecting the rotation of the impeller.

[0003] However, in actual use, there will inevitably be smaller foreign matter and impurities in the water that cannot be intercepted by the interception mesh. When water is pumped by the water pump, the water flows into the pump casing under the action of the centrifugal force generated by the rotation of the impeller. Small foreign matter in the water will also follow the water flow into the pump casing and perform centrifugal motion in the pump casing. Since the existing pump casing is usually made of thinner aluminum alloy plates, small foreign matter will hit or rub the inner wall of the pump casing when rotating under the action of centrifugal force, which can easily cause scratches on the inner wall of the pump casing. Especially when there are sharp edges on the foreign matter, when the foreign matter hits the inner wall of the pump casing, it is easy to cause the inner wall of the pump casing to be cut through, or even cause the inner wall of the pump casing to be cut off as a whole, affecting subsequent use.

[0037] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0038] The embodiment of the present application discloses a vertical water pump.

[0039] Example 1:

[0040] Reference Figure 1 and Figure 2 A vertical water pump comprises a pump casing 1, an impeller 2, a pump shaft 3, a pump base 4, a drive motor 5 and an interception net cover 6, wherein the pump base 4 is placed horizontally as a whole, the pump casing 1 is located above the pump base 4, a water inlet 20 is formed between the pump casing 1 and the pump base 4, the interception net cover 6 is mounted on the pump base 4 by bolts, and the interception net cover 6 is used to intercept larger foreign objects at the water inlet 20, the drive motor 5 is mounted on the pump base 4, one end of the pump shaft 3 is coaxially fixedly connected to the output shaft of the drive motor 5, and the other end of the pump shaft 3 is coaxially fixedly connected to the impeller 2, the impeller 2 is located in the pump casing 1, and a water outlet 30 is opened at the end of the pump casing 1 away from the pump base 4.

[0041] Reference Figure 1 and Figure 2When in use, the water pump is fixed to the outside world through the pump seat 4, and then the pump shaft 3 can be driven to rotate by rotating the output shaft of the drive motor 5. The rotation of the pump shaft 3 synchronously drives the impeller 2 to rotate, thereby generating centrifugal force between the impeller 2 and the inner wall of the pump casing 1. Under the action of centrifugal force, water flows in from the water inlet 20 and flows out from the water outlet 30; during the entire pumping process, the interception mesh cover 6 intercepts larger foreign objects in the water, thereby reducing the possibility of large foreign objects entering the pump casing 1 and affecting the rotation of the impeller 2.

[0042] Reference Figure 2 and Figure 3 When pumping water, it is inevitable that small foreign objects will be mixed in the water. Driven by the water flow, they enter the pump casing 1 through the mesh of the intercepting mesh cover 6 and rotate under the action of centrifugal force. At the same time, they will hit the inner wall of the pump casing 1. At this time, if there are relatively sharp edges on the foreign objects, it is easy to cut through the pump casing 1 or even cut off the entire pump casing 1, which has a great impact on the subsequent use of the water pump. In order to reduce the possibility of the above situation, a stainless steel collar 7 is added in the present application, that is, a mounting groove 11 is opened at one end of the pump casing 1 close to the impeller 2, and the mounting groove 11 is connected to the inside of the pump casing 1. Then the stainless steel collar 7 can be installed in the mounting groove 11.

[0043] Reference Figure 2 and Figure 3 In this embodiment, the stainless steel collar 7 is an annular structure made of stainless steel, and the outer diameter of the stainless steel collar 7 is slightly larger than the distance between the bottom of the mounting groove 11 and the axis of the impeller 2, that is, the outer wall of the stainless steel collar 7 and the inner wall of the mounting groove 11 are interference fit. Therefore, during installation, the stainless steel collar 7 is actually pressed into the mounting groove 11 by press-fitting. After the stainless steel collar 7 is installed, the inner wall of the stainless steel collar 7 is flush with the inner wall of the pump casing 1 near the water outlet 30.

[0044] Reference Figure 2 and Figure 3 A first guide bevel 12 is formed on the edge of the notch of the installation groove 11 near the pump seat 4. When in use, the stainless steel collar 7 is guided by the first guide bevel 12 to be embedded in the installation groove 11, thereby facilitating the installation of the stainless steel collar 7; in addition, a second guide bevel 71 is provided on the inner wall of the end of the stainless steel collar 7 near the pump seat 4. The bottom end of the second guide bevel 71 is located below the top end of the first guide bevel 12. Therefore, when in use, the first guide bevel 12 and the second guide bevel 71 can be used in conjunction to guide water flow into the pump casing 1, thereby ensuring the operating efficiency of the water pump.

[0045] The implementation principle of the embodiment of the present application is as follows: before use, the stainless steel collar 7 is first pressed onto the inner wall of the pump casing 1, and then the drive motor 5 is started to drive the impeller 2 to rotate. Under the action of the centrifugal force generated by the rotation of the impeller 2, water flows into the pump casing 1 from the water inlet 20 and is discharged from the water outlet 30, thereby achieving water pumping; during the water pumping process, foreign matter in the water hits the stainless steel collar 7 under the action of centrifugal force, thereby limiting the flow direction of the foreign matter through the inner wall of the stainless steel collar 7, that is, ensuring that the foreign matter is discharged from the water outlet 30 together with the water flow. In this process, the stainless steel collar 7 is used to prevent foreign matter from directly contacting the pump casing 1, thereby reducing the possibility of damage to the inner wall of the pump casing 1 when foreign matter hits the pump casing 1, thereby achieving protection of the pump casing 1 and being more conducive to use.

[0046] Example 2:

[0047] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the outer wall diameter of the stainless steel collar 7 is slightly smaller than the distance between the side wall of the mounting groove 11 and the axis of the impeller 2, that is, there is a clearance fit between the outer wall of the stainless steel collar 7 and the side wall of the mounting groove 11; in addition, in order to increase the structural strength of the stainless steel collar 7, a reinforcing rib 72 is integrally formed on the outer wall of the stainless steel collar 7, and a plurality of reinforcing ribs 72 are provided, and the plurality of reinforcing ribs 72 are evenly distributed on the circumference of the outer wall of the stainless steel collar 7, and an embedding groove 13 corresponding to the reinforcing rib 72 is opened on the side wall of the mounting groove 11, and the embedding groove 13 is used to embed the reinforcing rib 72.

[0048] Reference Figure 4 and Figure 5 When in use, the stainless steel collar 7 is slid into the mounting groove 11, and a clamping structure 8 is provided on the pump housing 1, so that the stainless steel collar 7 is clamped and fixed in the mounting groove 11 through the clamping structure 8, thereby realizing the installation of the stainless steel collar 7, and the provision of several reinforcing ribs 72, on the one hand, increases the structural strength of the stainless steel collar 7, and on the other hand, realizes the positioning of the stainless steel collar 7, thereby facilitating the installation of the clamping structure 8. At the same time, a third guide bevel 74 is formed at one end of the reinforcing rib 72 facing the water outlet 30, that is, the cooperation between the third guide bevel 74 and the first guide bevel 12 facilitates the embedding of the reinforcing rib 72 into the embedding groove 13, thereby facilitating the installation of the stainless steel collar 7.

[0049] Reference Figure 4 and Figure 5The clamping structure 8 is composed of a number of locking bolts 81, and the locking bolts 81 are evenly distributed around the pump casing 1. In this embodiment, the locking bolts 81 are preferably arranged in three groups, and connecting holes 73 are opened on the outer walls of the three reinforcing ribs 72. The connecting holes 73 are arranged in a one-to-one correspondence with the locking bolts 81. When in use, one end of the locking bolt 81 is passed through the side wall of the pump casing 1 and threadedly connected to the connecting hole 73, so that the stainless steel ring 7 can be installed in the mounting groove 11.

[0050] Reference Figure 4 and Figure 5 In order to further improve the structural strength of the stainless steel collar 7, the inner wall of the stainless steel collar 7 may be plated with a nano coating 9 or titanium. In this embodiment, the nano coating 9 is preferably provided. Thus, during the pumping process, the structural strength and corrosion resistance of the nano coating 9 itself further reduce the possibility of damage to the stainless iron collar during the pumping process.

[0051] The implementation principle of the embodiment of the present application is: before use, the stainless steel collar 7 is first embedded in the installation groove 11, and then the stainless steel collar 7 is fixed by the locking bolt 81, and then the drive motor 5 can be started to drive the impeller 2 to rotate. Under the action of the centrifugal force generated by the rotation of the impeller 2, water flows into the pump casing 1 from the water inlet 20 and is discharged from the water outlet 30, thereby realizing water pumping; during use, the locking bolt 81 is used to ensure the installation stability of the stainless steel collar 7, thereby ensuring the protective effect of the stainless steel collar 7 on the pump casing 1, and at the same time, the setting of the locking bolt 81 is also convenient for the staff to dismantle, thereby realizing the detachable and replaceable stainless steel collar 7, which is more convenient for use.

[0052] Example 3:

[0053] Reference Figure 6 The difference between this embodiment and embodiment 1 is that, in this embodiment, the inner wall of the stainless steel collar 7 is further integrally formed with a guide ridge 10, and a plurality of guide ridges 10 are provided. The plurality of guide ridges 10 are evenly spaced along the circumference of the stainless steel collar 7, and each guide ridge 10 is spirally arranged upward along the axis of the stainless steel collar 7, and the spiral direction of the guide ridge 10 is the same as the direction of the impeller 2; when in use, the coordinated arrangement of the plurality of guide ridges 10, on the one hand, strengthens the structural strength of the stainless steel collar 7, thereby ensuring the use quality of the stainless steel collar 7, and on the other hand, guides the water flow and foreign matter in the water through the spiral direction of the guide ridges 10, thereby reducing the possibility of foreign matter in the water cutting through the inner wall of the stainless steel collar 7, and the overall use is more convenient.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
