Description

Technical Field

[0001] This utility model belongs to the technical field of water supply pump devices, specifically relating to a novel steam-driven water supply pump device. Background Technology

[0002] A water pump, as the name suggests, is mainly used in water supply systems to increase water pressure and transport water flow. It utilizes the power of an electric motor or steam turbine, converting mechanical energy into the kinetic and pressure energy of the liquid through the rotation of the impeller, thereby transporting the liquid from a low-pressure area to a high-pressure area. Water pumps are widely used in industry, agriculture, and urban water supply, and are key equipment for ensuring the effective utilization and transportation of water resources.

[0003] A significant problem exists during the use of water pump units: when the motor is connected to the pump body via a flange, the flange connection area lacks effective protection, making it easy for dust to accumulate on the connecting bolts. This situation not only makes subsequent maintenance by disassembling and assembling the bolts extremely cumbersome, but also significantly increases maintenance efficiency, as the dust on the bolts must be removed before disassembly and assembly can be carried out, thus prolonging the disassembly and assembly time and affecting the overall maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel steam-driven feedwater pump device, aiming to solve the problem in the prior art where, when the motor is connected to the pump body via a flange, dust easily accumulates on the connecting bolts due to the lack of effective protection in the flange connection area. This situation not only makes subsequent maintenance by disassembling and assembling the bolts extremely cumbersome, but also significantly increases maintenance efficiency, as dust on the bolts must be removed before disassembly and assembly can be performed, thus prolonging the disassembly and assembly time and affecting the overall maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel steam-driven water pump device, comprising a base, a motor and a pump body, wherein the output shaft of the motor is connected to a flange and connected to the impeller of the pump body, a screw is vertically connected to the top of the base, a protective cover is provided at the top of the flange, and a nut is threaded onto the surface of the screw.

[0006] As a preferred embodiment of the novel steam-driven water pump device of this utility model, the protective cover is made of metal, and the size of the protective cover is larger than the size of the flange.

[0007] As a preferred embodiment of the novel steam-driven water pump device of this utility model, the protective cover is detachably fixedly connected by nuts and screws.

[0008] In a preferred embodiment of this novel steam-driven water pump device, a fixing block is connected to the top of the base, and a fixing box is connected to the top of the fixing block.

[0009] As a preferred embodiment of the novel steam-driven water pump device of this utility model, the surface of the fixed box is provided with a through hole, and a cooling fan is installed on the inner side wall of the fixed box.

[0010] As a preferred embodiment of the novel steam-driven water pump device of this utility model, the surface of the fixed block is provided with an air inlet hole, which is connected to the through hole.

[0011] In a preferred embodiment of this novel steam-driven water pump device, the exhaust end of the cooling fan is the same as the through hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes a protective cover to effectively shield the flange, ensuring that the flange and its connecting bolts are not disturbed by dust. This design significantly improves the convenience of flange disassembly and assembly during maintenance, effectively shortens maintenance time, and thus improves the overall maintenance efficiency of the water pump. Furthermore, by configuring a cooling fan, effective heat dissipation can be achieved for the motor and pump body, preventing them from overheating due to prolonged operation, thereby effectively extending the service life of the motor and pump body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a novel steam-driven water pump device, comprising a base 3, a motor 1 and a pump body 2, wherein the output shaft of the motor 1 is connected to a flange 4 and is connected to the impeller of the pump body 2, a screw 7 is vertically connected to the top of the base 3, a protective cover 5 is provided on the top of the flange 4, and a nut 6 is threaded onto the surface of the screw 7.

[0022] In a preferred embodiment: the protective cover 5 is made of metal, and the size of the protective cover 5 is larger than the size of the flange 4.

[0023] In a preferred embodiment, the protective cover 5 is detachably fixedly connected by a nut 6 and a screw 7.

[0024] In this embodiment, the novel steam-driven feedwater pump is a mature existing technology, primarily based on centrifugal force. When the electric motor or turbine starts (i.e., motor 1 drives pump body 2), it initiates operation, driving the impeller within the pump to rotate. As the impeller rotates, its blades perform work on the liquid, giving it kinetic energy. As the impeller continues to rotate, the liquid is forced through the channels inside pump body 2, gradually increasing its kinetic energy and pressure. Ultimately, the high-pressure liquid is pushed towards the pump's outlet and transported to the desired location via pipeline.

[0025] Furthermore, during routine maintenance of the water pump, workers need to use tools to first remove nut 6 from screw 7. It is worth noting that the connection between nut 6 and screw 7 is equipped with a sealing cover structure. This prevents the protective cover 5 from interfering with the protection of flange 4 during installation, thus avoiding difficulties in disassembling and assembling the protective cover 5 itself. After removing nut 6, the protective cover 5 can be easily removed, exposing flange 4. Through this design, the protective cover 5 effectively shields flange 4 during normal use, ensuring that flange 4 and its connecting bolts are not contaminated by dust. This ingenious design significantly improves the convenience of disassembling and assembling flange 4 during maintenance, effectively shortens the maintenance time, and thus greatly improves the overall maintenance efficiency of the water pump. Example

[0026] Please see Figure 1-4 The top of the base 3 is connected to a fixing block 8, and the top of the fixing block 8 is connected to a fixing box 9.

[0027] In a preferred embodiment: a through hole 12 is provided on the surface of the fixing box 9, and a cooling fan 10 is installed on the inner side wall of the fixing box 9.

[0028] In a preferred embodiment: an air inlet 11 is provided through the surface of the fixing block 8, and the air inlet 11 is connected to the through hole 12.

[0029] In a preferred embodiment, the exhaust end of the cooling fan 10 is the same as the through hole 12.

[0030] In this embodiment, the operator manually connects the power supply to the cooling fan 10 to start its operation. Subsequently, the airflow generated by the cooling fan 10 is smoothly discharged through the through hole 12 via the mounting box 9, directly acting on the motor 1 and the pump body 2 to achieve effective cooling. This mechanism ensures that the temperature of the motor 1 and the pump body 2 is effectively controlled during long-term operation, preventing overheating and thus significantly extending the service life of the motor 1 and the pump body 2.

[0031] It is worth noting that the mounting box 9 facilitates the installation of the cooling fan 10, while also protecting the cooling fan 10 and preventing accidental damage caused by its lack of protection.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
