Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a durable water pump component. Background Art

[0002] A booster pump is a device used to increase the pressure of a fluid (such as water or gas). It does this by moving the fluid from a low-pressure area to a high-pressure area. The operating principle of a booster pump is based on the law of conservation of mass and Bernoulli's principle. When a booster pump introduces fluid and accelerates its flow, the flow rate increases, and its kinetic energy is enhanced, creating a pressure differential that causes the fluid to move toward the high-pressure area.

[0003] In the current daily use process, when you are on vacation or away from home for a long time, the booster pump will be in a static state for a certain period of time. During this period, its impeller is placed in the water in the pump head. The impeller will be immersed in water for a long time, which will cause rust and corrosion. When it is turned on next time, it will cause a jamming malfunction due to rust, affecting normal use. Utility Model Content

[0004] The purpose of the present utility model is to provide a durable water pump assembly to solve the problems raised in the above background technology.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1、 2 As shown in Figures 3, 4, and 5, the utility model provides a technical solution: a durable water pump assembly, comprising: a driving part 1; a pump head 2 fixedly mounted on the output end of the driving part 1, a drain pipe 10 being provided at the bottom of the pump head 2 for draining the accumulated water in the pump head 2; a sealing cover plate 7 being mounted on one side of the pump head 2 by screws, an electric heating plate 12 being fixedly mounted on the inner side of the sealing cover plate 7 for antifreeze and keeping the inside of the pump head 2 dry; a water tank 14 being fixedly mounted on the top of the pump head 2, the water tank 14 being connected to the pump head 2, a pressure tank 3 being fixedly mounted on one side of the water tank 14, an inflatable air bag being installed inside the pressure tank, and the rest of the pressure tank being filled with water. The air bag is filled with air or nitrogen, which acts as a buffer. When the booster pump is working and water is pressed into the system, the water will enter the pressure tank and compress the air therein to store energy. When the faucet or other water-using equipment in the system is turned on, the compressed air in the pressure tank will push the water out to keep the water pressure stable.

[0024] It should be noted that when the utility model pumps water, the driving part 1 drives the impeller inside the pump head 2 to rotate, and pumping is achieved under the action of negative pressure. When the user is away for a long time or the water pump does not work for a long time, the water inside the pump head 2 is drained through the drain pipe 10, and then the inside of the pump head 2 is dried through the electric heating plate 12 to ensure the dryness of the inside of the pump head 2 and prevent the impeller from being soaked in water for a long time or in a humid environment to cause rust, thereby causing the machine to jam during use.

[0025] See also Figure 2 As shown, the driving part 1 is a motor, a heat dissipation cover is provided at one end of the motor, and a control panel 8 is fixedly connected to the top of the driving part 1.

[0026] It should be noted that the heat dissipation cover provided at one end of the motor of the utility model helps to effectively disperse the heat generated by the operation of the motor, prevent the motor from overheating, thereby protecting the motor and extending its service life. The control panel includes switches, speed adjustment, automatic start and stop control, and fault indication functions, which are convenient for cooperating with the motor to monitor the working status in real time, adjust the operating parameters in time to cope with different working environments, and ensure the stable operation of the water pump system.

[0027] See also Figure 2 、 3 As shown, the interior of the pump head 2 is rotatably connected to the impeller, the output end of the driving part 1 is fixedly connected to the impeller, the bottom of the pump head 2 is fixedly connected to a connector 9, the drain pipe 10 is rotatably connected to the bottom of the connector 9, and the middle of the drain pipe 10 is fixedly connected to a valve 11.

[0028] It should be noted that after the motor of the utility model is started, the impeller is driven to rotate through its output shaft. The rotation of the impeller generates centrifugal force, which pushes water to the outlet of the pump. The connector 9 is a water pipe connector. The drain pipe 10 can be rotated at the end of the connector 9, so that the direction of the drain pipe 10 can be adjusted to adapt to different installation and drainage requirements. The opening and closing of the valve can adjust the flow rate or completely cut off the flow, making it convenient and quick to drain the water without the need for other auxiliary tools.

[0029] See also Figure 2 As shown, a temperature sensor 6 is fixed to one side of the water tank 14 , a humidity sensor 13 is fixed to the side of the sealing cover 7 , and both the temperature sensor 6 and the humidity sensor 13 are electrically connected to the control panel 8 .

[0030] It should be noted that the utility model can detect the water temperature inside the water tank 14 during use. When the low temperature threshold is reached, the control panel 8 controls the electric heating plate 12 to heat up, so as to prevent ice from affecting the operation of the pump head 2. When the water inside the pump head 2 is drained, the humidity inside the pump head 2 is detected by the humidity sensor 13, and the internal humidity is adjusted by heating with the electric heating plate 12 to prevent the pump head 2 from rusting and causing operation jams.

[0031] See also Figure 1 、 2 As shown in FIG. 4 , a water inlet 5 is fixedly connected to the side of the water tank 14 , and a water outlet 4 is fixedly connected to the top of the water tank 14 .

[0032] It should be noted that the water tank 14 of the utility model is connected to the pump head 2, and there is a direct fluid channel between the pump head and the water tank. The pump head is located at the bottom of the water tank, and a water inlet 5 is fixed on the side of the water tank for introducing fluid into the water tank; the impeller in the pump head rotates under the drive of the motor, and the rotation action draws the water in the water tank into the pump head through the centrifugal force generated; after the water is accelerated by the impeller, it is pushed outward through the outlet provided in the pump head, and the fluid will be discharged directly from the water outlet 4 of the water tank.
