A novel jet pump body structure

Abstract

This utility model discloses a novel jet pump body structure, including a pump body with a Venturi tube inside. The front end of the Venturi tube is an inlet section. A support seat is installed on the pump body at the front end of the Venturi tube inlet section to support the Venturi tube. The support seat has an opening in the middle, and two detachable and fixed inner diameter adjustment plates are installed on the two sides of the inner side of the support seat with the middle opening. This utility model can effectively increase the head of the jet pump by adding magnetic adhesive plates to the support seat to modify the inner diameter of the support seat. At the same time, a groove is cut on the inclined surface of the support seat at the middle opening at the front end of the Venturi tube inlet section of the jet pump body. When the pump is running, the fluid circulates in the pump chamber through the Venturi tube. When the fluid passes through this groove, the flow velocity increases, which can effectively increase the flow velocity of the fluid through the narrow opening of the Venturi tube, further increasing the static pressure inside the pump chamber and increasing the head.

Description

Technical Field

[0001] This utility model relates to the field of jet pump technology, and in particular to a novel jet pump body structure. Background Technology

[0002] Jet pumps are widely used due to their strong self-priming capability, high self-priming height, low net positive suction head (NPSH), high shut-off head, and ease of use. For example... Figure 1 As shown, an existing jet pump includes a pump body 1, a Venturi tube 2 installed inside the pump body, an inlet section 3 at the front end of the Venturi tube, and a support 4 installed on the pump body at the front end of the inlet section of the Venturi tube for supporting the Venturi tube. The support 4 has an opening in the middle to allow the fluid to enter smoothly. When the jet pump is running, the fluid circulates within the pump chamber through the Venturi tube. Jet pumps mainly rely on the kinetic energy of the high-speed jet and the Venturi effect to convert mechanical energy into static pressure. Their head is often limited without changing other conditions.

[0003] Existing jet pumps may have insufficient head, and changing their configuration would significantly increase costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a novel jet pump body structure, which can effectively increase the jet pump head without changing other conditions.

[0005] The present invention adopts the following technical solution: A novel jet pump body structure includes a pump body, a venturi tube disposed within the pump body, the front end of the venturi tube being an inlet section, a support seat mounted on the pump body at the front end of the venturi tube inlet section for supporting the venturi tube, the support seat having an opening in the middle, and two detachable and fixedly mounted inner diameter adjustment plates on the two inner sides of the support seat with the middle opening.

[0006] Preferably, the inner diameter adjustment piece of the support base is a magnetic element, which is magnetically attached to both sides of the inner side of the support base.

[0007] Preferably, the pump body has a recessed groove at the middle opening of the support seat located at the front end of the venturi tube inlet section.

[0008] Preferably, the inner diameter adjusting piece of the support base is an arc shape with an arc shape that matches the inner diameter of the support base.

[0009] The beneficial effects of this utility model are as follows: This utility model designs a novel jet pump body structure. By adding a magnetic adhesive patch to the support seat, the inner diameter of the support seat is modified, which can effectively increase the head of the jet pump. At the same time, a groove is opened on the inclined surface of the support seat at the middle opening of the front end of the venturi tube inlet section of the jet pump body. When the pump is running, the fluid circulates in the pump chamber through the venturi tube. When the fluid passes through this groove, the flow velocity increases, which can effectively increase the flow velocity of the fluid through the narrow opening of the venturi tube, further increasing the static pressure inside the pump chamber and increasing the head.

[0011] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figures 2-4 As shown, a novel jet pump body structure includes a pump body 1, a venturi tube 2 disposed inside the pump body, an inlet section 3 at the front end of the venturi tube, and a support seat 4 installed on the pump body at the front end of the venturi tube inlet section for supporting the venturi tube. The support seat has an opening in the middle, and two sides of the inner side of the support seat with the middle opening are detachably and fixedly installed with inner diameter adjustment plates 5.

[0012] Preferably, the inner diameter adjustment piece of the support base is a magnetic element, which is magnetically attached to both sides of the inner side of the support base.

[0013] Preferably, the pump body has a recessed groove 6 at the middle opening of the support seat located at the front end of the venturi tube inlet section.

[0014] Preferably, the inner diameter adjusting piece of the support base is an arc shape with an arc shape that matches the inner diameter of the support base.

[0015] This invention designs a novel jet pump body structure. By adding magnetic adhesive patches to the support base, the inner diameter of the support base is modified, which can effectively increase the head of the jet pump. At the same time, a groove is cut into the inclined surface of the support base at the middle opening of the front end of the venturi tube inlet section of the jet pump body. When the pump is running, the fluid circulates in the pump chamber through the venturi tube. When the fluid passes through this groove, the flow velocity increases, which can effectively increase the flow velocity of the fluid through the narrow opening of the venturi tube, further increasing the static pressure inside the pump chamber and increasing the head.
