Description

Technical Field

[0001] The utility model belongs to the technical field of pumps, and in particular relates to a high-lift stainless steel stamping deep well pump. Background Art

[0002] The biggest feature of the deep well pump is that the motor and the pump are made into one, and the whole is cylindrical. It is a pump immersed in the groundwater well to suck and transport water. It is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Because the motor is also submerged in water, the structural requirements for the motor are more special than those for general motors.

[0003] When the deep well pump reaches the well below, the deep well pump is placed into the well through a sling. However, when the water pumping volume is large, a single deep well pump cannot meet the requirements and multiple deep well pumps are needed. People need to place the water pumps into the well one by one, which is troublesome to operate.

[0004] However, the existing open document CN204025001U deep well pump can be connected to each other. After the connection is completed, they can be put into the well at the same time through the same lifting device, without having to put them into the well one by one, which is simple to operate; and the height of multiple deep well pumps can be controlled at the same time to improve the working efficiency of each deep well pump. However, when multiple deep well pumps are connected to each other, their overall diameter will become larger, and some wells have a small diameter. If multiple deep well pumps are connected to each other to increase the pumping capacity, it will be limited by the well diameter, resulting in poor applicability. Utility Model Content

[0020] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0021] like Figure 1-Figure 4As shown, this embodiment provides a high-lift stainless steel stamping deep well pump, characterized in that it includes a pump barrel 1 and a plurality of impeller groups 2, wherein the plurality of impeller groups 2 are superimposed and installed in the pump barrel 1, and the water outlet end of the pump barrel 1 is threadedly connected with a gland 3, and a water outlet connecting pipe 4 is installed on the gland 3. When in use, multiple impeller groups 2 are installed in the pump barrel 1 according to actual needs, and then the gland 3 locks the impeller group 2, so that the impeller group 2 is stably placed in the pump barrel 1, and the displacement is increased or decreased by increasing or decreasing the number of impeller groups 2, and the pumping amount can be increased by multiple superpositions without changing the diameter. Specifically, the deep well pump also includes an extension pipe 10, and the outer wall of the water outlet end of the pump barrel 1 is provided with an external thread, and a threaded sleeve 11 is extended and installed below the extension pipe 10, and the threaded sleeve 11 is threadedly connected with the external thread, and the upper inner wall of the extension pipe 10 is provided with an internal thread threadedly connected with the gland 3. And the pump barrel 1 can be increased by adding an extension pipe 10 so that more impeller groups 2 can be placed to increase the pumping amount.

[0022] Furthermore, the gland 3 is provided with lifting rings 5 ​​on both sides corresponding to the water outlet connecting pipe 4. The lifting rings 5 ​​facilitate lifting the pump barrel 1, thereby facilitating transportation.

[0023] Furthermore, a telescopic tube 6 connected to the water outlet connection pipe 4 is installed on the side of the gland 3 facing the inside of the pump barrel 1, and a top plate 7 is installed on the end of the telescopic tube 6 away from the gland 3, and a plurality of springs 8 are connected between the top plate 7 and the gland 3. Specifically, the plurality of springs 8 are arranged equidistantly around the telescopic tube 6. When the gland 3 is tightened, the elastic force of the plurality of springs 8 pushes the top plate 7 to press against the impeller assembly 2 to form a clamping adaptive force, so as to prevent the gland 3 from rotating too tightly and damaging the impeller assembly 2.

[0024] Furthermore, the outer walls of the plurality of impeller groups 2 are all provided with sealing sleeves 9, and the sealing sleeves 9 are fitted with the inner wall of the pump barrel 1, so as to increase the sealing performance between the impeller group 2 and the inner wall of the pump barrel 1.

[0025] Furthermore, a reinforcement strip 12 is installed on the outer wall of the pump barrel 1, and the two ends of the reinforcement strip 12 are respectively connected to the water inlet end of the pump barrel 1 and the gland 3 by bolts, thereby increasing the strength of the entire deep well pump.
