Description

Technical Field

[0001] This utility model relates to the technical field of directional pump water flow control devices, and in particular to a directional pump water flow control device based on a mechanical seal. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. A directional pump, on the other hand, is a pump whose suction and discharge directions cannot be changed.

[0003] When using a directional pump to extract liquids, the pumping speed needs to be adjusted according to usage requirements to regulate the water flow. In existing technologies, a regulating valve is typically installed at the pump's outlet to control and regulate the flow. However, this method is prone to damage to the valve's seals, especially under high water pressure, which can cause leakage at the valve's connection to the outlet pipe, affecting usability. Therefore, a mechanical seal-based directional pump flow control device is designed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose a directional pump water flow control device based on a mechanical seal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a directional pump water flow control device based on a mechanical seal, comprising a base plate, a motor, a rotating shaft, an outer steel pipe, an inner steel pipe, an inlet pipe, and an outlet pipe. The motor is fixedly installed on the right side of the upper surface of the base plate. A rotating shaft is installed at the output end of the motor.

[0027] Example

[0028] like Figures 1-5 As shown, an embodiment of this utility model provides a directional pump flow control device based on a mechanical seal, including a base plate 1, a motor 2, a rotating shaft 3, an outer steel pipe 4, an inner steel pipe 5, an inlet pipe 6, and an outlet pipe 7. The motor 2 is fixedly installed on the right side of the upper surface of the base plate 1. The rotating shaft 3 is installed at the output end of the motor 2. A guide head 301 is fixedly installed at the right end of the rotating shaft 3. Multiple guide vanes 302 are fixedly installed on the left side of the guide head 301. The outer steel pipe 4 is fixedly installed on the right side of the base plate 1, and a guide vane 302 is rotatably installed on the inner side of the outer steel pipe 4. The inner steel pipe 5 and the outer steel pipe 4 are fixedly installed with a water inlet pipe 6 through a flange on the right end. A water outlet pipe 7 is installed through the center of the upper surface of the outer steel pipe 4. A water flow regulating hole 501 is opened above the outer surface of the inner steel pipe 5. A connection hole 401 is opened on the left side of the outer steel pipe 4. A connecting pipe 502 is installed through the center of the left end of the inner steel pipe 5. A waterproof bearing 503 is fixedly installed on the inner side of the connecting pipe 502. A drive assembly for driving the inner steel pipe 5 to rotate along the outer steel pipe 4 is installed on the connecting pipe 502 and the left side surface of the outer steel pipe 4.

[0029] In actual use, the motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the guide head 301 and the guide vane 302 to rotate. The guide head 301 draws the water inlet pipe 6 to the inner steel pipe 5, and the guide vane 302 swings the outer side of the inner steel pipe 5 of the water network, so that the water flows through the water flow regulating hole and is discharged through the outlet pipe 7, thus achieving the effect of directional water pumping.

[0030] In this embodiment, the water flow regulating hole 501 and the water outlet pipe 7 are on the same vertical plane, and the water flow regulating hole 501 is shaped like a shoe with one end larger than the other. The diameter of the larger end of the water flow regulating hole 501 is equal to the internal diameter of the water outlet pipe 7, so that the water flow speed of the water outlet pipe 7 can be adjusted by using the water flow regulating hole 501 at different positions to accurately align with the water outlet pipe 7.

[0031] In this embodiment, the connecting tube 502 matches the connecting hole 401, and the connecting tube 502 rotates and passes through the left end of the connecting hole 401.

[0032] In this embodiment, a sealing ring 5021 is fixedly provided on the right side of the outer surface of the connecting pipe 502, and an annular groove 4011 is provided in the center of the inner side of the connecting hole 401.

[0033] In this embodiment, the sealing ring 5021 and the annular groove 4011 are matched, and the sealing ring 5021 is embedded in the annular groove 4011 to achieve the effect of mechanical sealing at the connection between the connecting pipe 502 and the connecting hole 401. The sealing ring 5021 is made of stainless steel and has good wear resistance, which increases its service life.

[0034] In this embodiment, the inner rotating ring of the waterproof bearing 503 is fixedly disposed on the outer surface of the rotating shaft 3, and the guide head 301 and the guide blade 302 are both located inside the inner steel tube 5.

[0035] In this embodiment, the guide vane 302 is on the same vertical plane as the water flow regulating hole 501 and the water outlet pipe 7.

[0036] By setting an outer steel pipe 4 and an inner steel pipe 5, when it is necessary to adjust the water flow, the inner steel pipe 5 is driven to rotate along the outer steel pipe 4 by the drive component, so that the water flow adjustment hole 501 on the inner steel pipe 5 is aligned with the water outlet pipe 7 at different positions, thereby achieving the effect of adjusting the flow rate of water discharged from the water outlet pipe 7. The operation is simple and convenient. Moreover, the outer steel pipe 4 and the inner steel pipe 5 are mechanically sealed by the sealing ring 5021 on the connecting pipe 502 and the annular groove 4011 on the connecting hole 401, which provides better waterproof effect.

[0037] In this embodiment, the drive assembly includes a gear ring 8 fixed to the left side of the outer end of the connecting pipe 502 and a rotating rod 9 rotatably disposed above the left side surface of the outer steel pipe 4. A gear 901 is fixedly disposed on the outer side surface of the rotating rod 9, and a turntable 902 is fixedly disposed on the left end of the rotating rod 9. A positioning assembly to prevent the gear 901 from rotating is also installed on the outer steel pipe 4.

[0038] In this embodiment, gear 901 meshes with gear ring 8.

[0039] In this embodiment, the positioning component is a pawl 10, which engages with the gear 901 when it is separable.

[0040] By incorporating a drive assembly and a positioning assembly, when the water flow rate of the outlet pipe 7 needs to be adjusted, the pawl 10 is disengaged from the gear 901. By rotating the turntable 902, the turntable 902 drives the rotating rod 9 and the gear 901 to rotate. The gear 901 drives the gear ring 8 and the inner steel pipe 5 to rotate along the outer steel pipe 4, so that the water flow adjustment hole 501 on the inner steel pipe 5 is aligned with the outlet pipe 7 at different positions, thereby achieving the effect of water flow rate adjustment. After adjustment, the pawl 10 engages with the gear 901 to achieve the effect of positioning and preventing the gear 901 from rotating, thus preventing the inner steel pipe 5 from rotating.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
