Description

Technical Field

[0001] The utility model relates to the technical field of submersible pump body structures, in particular to a submersible pump body structure with good corrosion resistance. Background Art

[0002] Submersible pump is a water-lifting machine with compact structure, easy to use and low price. It can be used in various occasions such as agricultural irrigation and drainage, environmental protection, municipal engineering, etc. Submersible pump can be divided into well submersible pump, working surface submersible pump, submersible sewage pump, sand discharge submersible pump, mining vertical pump, etc.

[0003] Currently available submersible pumps all work while submerged in water, and are usually sprayed with anti-rust primer when they leave the house. However, since there is no filtering device inside the water inlet pipe, fine impurities or particles in the water will also be sucked into the device. When passing through the pressurized pipe, the particles in the water are likely to scratch the anti-rust primer inside the device, causing the device to rust. In addition, rust may also increase the wear of the submersible pump, cause damage to components, and thus shorten its service life. Utility Model Content

[0014] Beneficial effects:

[0015] Compared with the prior art, the submersible pump body structure with good corrosion resistance has the following beneficial effects:

[0016] 1. After the utility model connects the external water pipe with the one-way water valve, the device is sunk into the water, and the water flows into the device through the water inlet filter hole and the water inlet filter cotton opened at the bottom of the device, and the water inlet filter cotton is arranged at the bottom of the device to filter the water flowing into the device, and the larger particles are isolated outside the device to prevent the particles and gravel from scratching the internal structure of the device and the anti-rust paint sprayed on the outer surface of the parts.

[0026] like Figure 1-3 As shown, the whole material of the water inlet filter cotton 102 is glass fiber, and a plurality of pressurizing blades 601 are fixedly connected to the outer walls at the bottom of the pressurizing device 6, and a water inlet baffle 602 is fixedly connected to the bottom surface of the pressurizing device 6, and special-shaped openings 603 are evenly opened at the center of the bottom surface of the water inlet baffle 602, and the special-shaped openings 603 correspond to the pressurizing blades 601, and the bottom surface of the pressurizing blades 601 is fixedly connected to the top surface of the water inlet baffle 602, and a plurality of seepage ports 701 are opened on the outer wall at the top of the pressurizing cover plate 7, and the top end of the inner wall of the pressurizing cover plate 7 is rotatably connected to the pressurizing device 6, and the seepage ports 701 correspond to the pressurizing blades 601.

[0027] After connecting the external water pipe to the one-way water valve 8, the device is sunk into the water, and the water flows into the device through the water inlet filter hole 101 and the water inlet filter cotton 102 opened at the bottom of the device, and the water flow entering the device is filtered by setting the water inlet filter cotton 102 at the bottom of the device, so that larger particles are isolated outside the device to prevent particles and gravel from scratching the internal structure of the device and the anti-rust paint sprayed on the outer surface of the parts. When the water flows through the water inlet filter cotton 102 and enters the device, the osmotic pressurizing device 6 drives the pressurizing paddle 601 by driving the pressurizing motor 5, so that the water flows through the seepage port 701 step by step upward to reach the water outlet tank 3, so that the device can filter the fine impurities in the water to enter the device during diving work, scratch the anti-rust paint inside the device, and cause rust stains on the internal parts of the device.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, a one-way resistance surface 801 is provided on the inner wall of the one-way water valve 8 near the water outlet bin 3, and a piston valve core 802 is slidably connected to the inner wall of the one-way water valve 8, an inclined surface is provided on the outer wall of one end of the one-way water valve 8 near the water outlet bin 3, and the inclined surface provided at one end of the one-way water valve 8 resists against the piston valve core 802, an end of the inner wall of the one-way water valve 8 away from the one-way resistance surface 801 is fixedly connected to a spring limiter 803, and a resistance spring 804 is fixedly connected to the outer wall on one side of the spring limiter 803, the resistance spring 804 is fixedly connected to one side of the plane of the piston valve core 802 at one end away from the spring limiter 803, and the piston valve core 802 is slidably connected to the inner center of the one-way water valve 8 through the resistance spring 804.

[0029] When the water flow is pressurized by the pressure motor 5 and enters the water outlet bin 3, the water flow resists the piston valve core 802 and compresses the resistance spring 804 by pushing the piston valve core 802, so that the piston valve core 802 moves away from the end of the water outlet bin 3, so that the water flow can pass through the outer wall of the piston valve core 802 and flow to the water pipe connected to the outside of the device. When the pressure motor 5 stops working, the resistance spring 804 is elastic and will push the piston valve core 802 to one end of the water outlet bin 3, and finally be blocked and fit with the one-way resistance surface 801, so that after the pressure motor 5 stops, the water flow that has been transported to the outside will not flow back into the device, thereby avoiding the pressure motor 5 from being inverted after power failure, causing damage to the device.

[0030] Working principle: After connecting the external water pipe to the one-way water valve 8, the device is sunk into the water, and the water flows into the device through the water inlet filter hole 101 and the water inlet filter cotton 102 opened at the bottom of the device, and the water inlet filter cotton 102 is set at the bottom of the device to filter the water entering the device, and the larger particles are isolated outside the device to prevent particles and gravel from scratching the internal structure of the device and the anti-rust paint sprayed on the outer surface of the parts. When the water flows through the water inlet filter cotton 102 and enters the device, the pressure motor 5 is driven to drive the osmotic pressure device 6 to drive the pressure blade 601, so that the water flows through the seepage port 701 level by level upward. , reaches the water outlet bin 3. When the water flow is pressurized by the pressure motor 5 and enters the water outlet bin 3, the water flow resists the piston valve core 802 and compresses the resistance spring 804 by pushing the piston valve core 802, so that the piston valve core 802 moves away from the end of the water outlet bin 3, so that the water flow can pass through the outer wall of the piston valve core 802 and flow to the water pipe connected to the outside of the device. When the pressure motor 5 stops working, the resistance spring 804 has elasticity and will push the piston valve core 802 to one end of the water outlet bin 3, and finally be blocked by the one-way resistance surface 801 and fit therewith, so that after the pressure motor 5 stops, the water flow that has been transported to the outside will not flow back into the device.
