Description

Technical Field

[0001] This utility model relates to the field of self-priming pump technology, specifically a horizontal-to-vertical self-priming pump body structure. Background Technology

[0002] Self-priming pumps are a type of self-priming centrifugal pump with advantages such as strong self-priming capability. No foot valve is required in the pipeline; only a certain amount of priming liquid needs to be present in the pump body before operation. Different materials can be used for self-priming pumps of different liquids. The working principle of a self-priming pump is as follows: before starting the pump, the pump casing is filled with water (or the pump casing itself contains water). After starting, the impeller rotates at high speed, causing the water in the impeller channels to flow towards the volute. At this time, a vacuum is formed at the inlet, causing the inlet check valve to open, allowing air from the suction pipe to enter the pump and reach the outer edge through the impeller channels.

[0003] Currently, most vertical self-priming pumps on the market are cylindrical structures with guide vanes (or blade diffusers). Commonly known as "toilet pumps," they are not only inefficient and noisy, but also complex in structure and unreliable. Once the mechanical seal fails, high-pressure water from the pump chamber will overflow through the bearing cavity, rendering the bearing unusable after being submerged. If the commonly used and relatively simple, reliable volute-type horizontal self-priming pump could be modified into a vertical structure, it could replace the inefficient and noisy "toilet pumps." Utility Model Content

[0004] The purpose of this invention is to provide a horizontal-to-vertical self-priming pump body structure to solve the problem of low efficiency of existing horizontal-to-vertical self-priming pump body structures.

The horizontal pump body has a pressure chamber, a liquid storage chamber, and a discharge chamber inside. The discharge chamber includes an inlet chamber and an outlet chamber. A suction chamber is formed between the pressure chamber and the inlet chamber of the discharge chamber. An impeller is rotatably mounted on the top wall inside the suction chamber.

[0006] Preferably, a bracket is installed on the upper part of the base, the bracket is sleeved on the outside of the horizontal pump body, and an extended shaft motor is installed on the upper part of the bracket.

[0022] like Figure 1 and Figure 5 As shown, a bracket 7 is installed on the upper part of the base 1. The bracket 7 is fitted onto the outside of the horizontal pump body 2, and an extended shaft motor 5 is installed on the upper part of the bracket 7. The output shaft of the extended shaft motor 5 is fixedly connected to the shaft center of the upper part of the impeller 3. A pump cover 4 is provided on one side of the horizontal pump body 2.

[0023] Specifically, a through-type threaded inner port is provided on one side of the discharge chamber 25, and the pump cover 4 is threaded in the cavity of the threaded inner port. The pump cover 4 and the horizontal pump body 2 are sealed with a sealing ring. The specific shape and installation method of the threaded inner port and the pump cover 4 are existing technologies and structures (such as the oil cap on the oil tank). Therefore, this application will not elaborate on them.

[0024] like Figure 1 and Figure 2 As shown, a double-chamber water tank 6 is provided on the upper part of the horizontal pump body 2. The double-chamber water tank 6 has an inlet chamber and an outlet chamber. The inlet pipe and outlet pipe are respectively fixedly connected to the side walls of the inlet chamber and the outlet chamber. The ends of the inlet pipe and the outlet pipe are fixedly fitted with flanges. The inlet chamber and the outlet chamber of the discharge chamber 24 are respectively connected to the inlet chamber and the outlet chamber on the double-chamber water tank 6.

[0025] like Figure 1 and Figure 2As shown, the upper part of the dual-chamber water tank 6 is provided with a liquid filling port 8, and the dual-chamber water tank 6 is fixedly connected to the liquid filling port 8 by a liquid filling threaded pipe, and a liquid filling sleeve cover is threaded on the outside of the liquid filling threaded pipe.

[0026] like Figure 1 - Figure 3 As shown, the diffuser 23 is located above the suction chamber 22, and the discharge chamber 25 is located above the suction chamber 22.

[0027] like Figure 1 - Figure 4 As shown, the reflux hole 26 is located inside the discharge chamber 25 and at a position 120° to 160° to the left of the tongue 27.

[0028] like Figure 1 - Figure 5 As shown, the horizontal pump body 2 adopts a volute type;

[0029] Specifically, the horizontal pump body 2 adopts a volute type, and the volute flow channel cavity is designed according to the performance parameters and other requirements input in the design.

[0030] Working principle: The medium liquid is drawn in through the suction chamber 22. After the impeller 3 of the self-priming pump does work, the liquid full of kinetic energy enters the diffuser 23 through the tongue 27 of the discharge chamber 25 and is sprayed into the discharge chamber 24. It then enters the discharge chamber of the double chamber water tank 6 to achieve gas-liquid separation.

[0031] Before the pump is started for the first time, self-priming circulating water is added to the storage chamber 21 through the filling port 8 on the dual-chamber water tank 6. The self-priming circulating water flows into the storage chamber 21 through the inlet chamber and suction chamber 22 of the dual-chamber water tank 6. After the pump is started, the extended shaft motor 5 drives the impeller 3 to rotate at high speed, mixing the air and water in the suction chamber 22 and forcing it into the discharge chamber 25, creating a vacuum in the suction chamber 22. The water vapor mixture is sprayed out through the discharge chamber 25, through the tongue 27, to the diffuser 23, and then rises to the dual-chamber water tank 6 connected to the discharge chamber 24 for gas-liquid separation. The gas is separated from the water and finally discharged through the outlet pipe. The separated water returns to the storage chamber 21 through the return hole 26 on the lower wall of the discharge chamber 25 and mixes with the newly drawn air again. This cycle continues until all the air in the suction pipe connected to the suction chamber 22 is expelled, and the external atmospheric pressure forces the water in the suction chamber 22 into the inlet of the impeller 3. The self-priming process is now complete, and the vertical self-priming pump is continuously supplying water and operating normally.
