Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and specifically relates to a stainless steel submersible pump with an adjustable filter base. Background Technology

[0002] A submersible pump is a positive pressure vertical water pump in which the impeller, pump body, and other flow components are submerged in the material being transported, and it is connected to a motor. It is manufactured according to the required length of insertion into the container. Submersible pumps can be broadly classified into two categories based on their explosion-proof rating: traditional submersible pumps and new submersible pumps. Traditional submersible pumps are suitable for transporting various corrosive materials such as strong acids, alkalis, salts, and strong oxidizers of any concentration. New submersible pumps are suitable for transporting flammable and explosive materials and are widely used in petroleum refining, oil depots, chemical plants, pharmaceutical factories, factory production lines, generator sets, and other locations where flammable and explosive materials are transported. To ensure good transport performance, it is necessary to prevent impurities and other solid particles in the medium from entering the pump and affecting its components and operation.

DETAILED DESCRIPTION

[0020] The following is a specific embodiment of the utility model and is further described in combination with the drawings, but the utility model is not limited to these embodiments.

[0021] As Figures 1 to 4As shown, the stainless steel submersible pump with adjustable filter base mainly comprises a pump body 100, a filter sleeve 200, an adjustable base 300, and a motor, a shaft tube, a liquid outlet pipe and other pump body structures. Since the submersible pump needs to be immersed in the medium environment for a long time, the whole submersible pump is made of stainless steel material. The stainless steel material makes the submersible pump have the characteristics of high strength, wear resistance, corrosion resistance and long service life. The bottom of the pump body 100 is formed with a pump body liquid inlet pipe 110. The filter sleeve 200 is installed at the bottom of the pump body 100 and is sleeved outside the pump body liquid inlet pipe 110. The adjustable base 300 is sleeved on the outer wall of the filter sleeve 200 and can be adjusted in height relative to it, which is convenient for actual installation and application.

[0022] As shown in the drawings, Figures 2 to 3 The structure of the filter sleeve 200 mainly comprises an inner filter cylinder 230, an outer filter cylinder 210 and a filter cylinder bottom cover 220. The outer filter cylinder 210 is formed with a connecting flange 211 at the top outer edge, and the connecting flange 211 is fixedly connected to the bottom of the pump body 100 by a filter cylinder mounting screw 212. A plurality of adjustment grooves 213 parallel to the axial direction of the outer filter cylinder 210 are uniformly arranged on the side wall of the outer filter cylinder 210. A plurality of first filter holes 214 are uniformly arranged on the side wall of the outer filter cylinder 210 between the adjustment grooves 213.

[0023] The outer filter cylinder 210 is formed with a conical bottom 215 at the bottom. A plurality of strip-shaped filter grooves 216 are uniformly arranged on the inclined side wall of the conical bottom 215 in the circumferential direction. The bottom of the strip-shaped filter groove 216 is designed as an opening, and the filter cylinder bottom cover 220 is detachably installed at the opening. The filter cover flange 221 is formed at the outer edge of the filter cylinder bottom cover 220, and the filter cover flange 221 is detachably installed at the bottom of the conical bottom 215 of the outer filter cylinder 210 by a bottom cover mounting screw 222. A plurality of bottom cover filter holes 223 are uniformly arranged on the center bottom cover of the filter cylinder bottom cover 220.

[0024] Further explanation, the first filter hole 214, the bottom cover filter hole 223, the adjustment groove 213 and the strip-shaped filter groove 216 are used for the first step rough filtration of the outer filter cylinder 210 and the filter cylinder bottom cover 220 to the external medium. The aperture of the first filter hole 214 and the bottom cover filter hole 223 is consistent, the groove width of the adjustment groove 213 and the strip-shaped filter groove 216 is consistent, and the groove width is equal to the filter hole aperture, so as to ensure the uniformity of the filter medium of the outer filter cylinder 210 and the filter cylinder bottom cover 220.

[0025] The inner filter cylinder 230 is an open upward cylinder structure, the side and bottom of which are formed by the secondary filter screen 231, the mesh of which is dense and smaller than the primary filter hole 214, etc. coarse filter aperture, used for the second step of fine filtering of the medium. The inner filter cylinder 230 and the outer filter cylinder 210 are coaxially arranged, and the inner filter cylinder 230 and the outer filter cylinder 210 are fixedly connected at the top through a plurality of filter cylinder connecting blocks 232 uniformly and integrally arranged in the circumferential direction. By arranging the filter sleeve 200 as an inner and outer double-layer nested type, the medium can pass through two filtering processes of coarse filtering and fine filtering in sequence, which can effectively prevent impurities and other solid particles in the medium from entering the submersible pump and affecting its components and operation, thereby improving the filtering quality and effect.

[0026] Further explanation, the medium after coarse filtering will leave impurity particles between the outer filter cylinder 210 and the inner filter cylinder 230 after fine filtering, and the conical bottom 215 can make these impurity particles accumulate downward to prevent the impurity particles from blocking the filter hole and the filter screen. The strip-shaped filter groove 216 can assist in discharging these impurities. If there are more impurities accumulated at the bottom of the outer filter cylinder 210, the filter cylinder bottom cover 220 can be disassembled for cleaning.

[0027] As shown in Figure 2 and Figure 4 , the adjustable base 300 is a hollow flat-topped cone as a whole, and an adjusting flange 310 is formed at the top thereof. A plurality of adjusting bolts 311 are uniformly installed on the adjusting flange 310 in the circumferential direction corresponding to the adjusting grooves 213 of the outer filter cylinder 210. By screwing the adjusting bolts 311 into the adjusting grooves 213, the relative height adjustment and fixation between the filter sleeve 200 and the adjustable base 300 can be realized, so that the submersible pump can be adjusted to adapt to different installation environments, and the practicality is stronger. A plurality of liquid inlet holes 320 are circumferentially arranged on the inclined side wall of the adjustable base 300, which are used for connecting the inside and outside of the base to facilitate the submersible pump to pump and transport the medium. The bottom of the adjustable base 300 is integrally formed with a fixed bottom plate 330, and a plurality of mounting bolt holes are arranged at the four corners of the fixed bottom plate 330. The adjustable base 300 and the entire submersible pump can be mounted on the bottom surface through the mounting bolt holes.

[0028] Further explanation, the number of adjusting grooves 213 arranged on the outer filter cylinder 210 should be not less than 2, preferably 4 or 8, and the number of adjusting bolts 311 installed on the adjusting flange 310 corresponds to the number of adjusting grooves 213, so as to facilitate the balance of the fixed connection between the filter sleeve 200 and the adjustable base 300.

[0029] Further explanation, the bottom of the pump body 100 is provided with an annular fixed clamping groove 120 on the stepped outer sidewall matched with the inner sidewall of the top of the outer filter cylinder 210, and an O-ring 121 is arranged in the fixed clamping groove 120. The O-ring 121 seals and tightly fixes the connection between the stepped portion of the pump body 100 and the outer filter cylinder 210.
