Description

Technical Field

[0001] The utility model relates to a high-pressure pump for wastewater transportation, in particular to a high-pressure pump for wastewater transportation applied in the field of pump equipment. Background Art

[0002] High-pressure pumps are suitable for use in the petroleum, chemical, and fertilizer industries as process pumps, high-pressure water descaling in metallurgy and steel rolling mills, high-pressure water cleaning and descaling in the construction, shipbuilding, sugar, papermaking, chemical and other industries, oil field water injection, boiler water supply, and hydraulic machinery power sources, as well as food, pharmaceuticals and other areas that require the generation of high-pressure liquids. The conveying medium is a fluid without solid particles. Existing high-pressure pumps require external water pipes for water delivery when in use, but traditional plastic water pipes have a short lifespan and insufficient clamping ability.

[0003] In order to solve the problems of low life and insufficient clamping ability of traditional plastic water pipes, the high-pressure pumps for wastewater transportation in the market adopt an external water pipe design with metal threaded connectors, which has a certain market share.

[0004] The existing high-pressure pumps for wastewater transportation use an external water pipe design with a metal threaded joint. Although this can increase the engagement ability between the pump and the pump, due to the high-pressure properties of the pump, the vibration force generated when the pump is started can easily loosen the interface between the two, causing water overflow and affecting the efficiency of the pump. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the vibration force generated when the pump is started can easily cause the interface between the two to loosen, resulting in water overflow and affecting the efficiency of the pump.

[0006] In order to solve the above problems, the utility model provides a high-pressure pump for wastewater transportation, including a pump body and a cylindrical L-shaped rod fixedly connected to the lower end of the pump body, the input end of the pump body is fixedly connected to an input port, the output end of the pump body is fixedly connected to an output port, the outer ends of the input port and the output port are both installed with water pipes, the end of the water pipe close to the pump body is fixedly connected to a metal joint, locking hoop sleeves are clamped between the two metal joints and the corresponding input and output ports, the vertical end and horizontal end of the cylindrical L-shaped rod are respectively clamped with a plurality of arc-shaped snap rings, the corresponding two arc-shaped snap rings are fixedly connected to an extended pull rod at one end away from the cylindrical L-shaped rod, and the end of the extended pull rod away from the arc-shaped snap ring is fixedly connected to a transverse staggered block.

[0007] In the above-mentioned high-pressure pump for wastewater transportation, the present solution uses the combined force of the extended pull rod and the transverse staggered block to increase the connection force between the locking hoop sleeve and the pump body, which helps to ensure the tightness of the pump body when transporting wastewater through a water pipe.

[0008] As a further improvement of the present application, a sealing gasket is clamped on the inner end of the locking hoop ring sleeve, and the two sealing gaskets are respectively sleeved outside the corresponding output port and input port.

[0009] As a further improvement of the present application, a notch is provided on the side of the arc-shaped buckle ring.

[0010] As a further improvement of the present application, the corresponding transversely staggered clamping blocks and the arc-shaped buckle rings are staggered, and the transversely staggered clamping blocks and the locking hoop sleeves are engaged with each other.

[0011] As another improvement of the present application, the lower end of the cylindrical L-shaped rod is fixedly connected to a triangular widened stable base, and the left end of the cylindrical L-shaped rod is rotatably connected to a transverse rod.

[0012] As another improved supplement of the present application, a plurality of arc-shaped abutment blocks are fixedly connected to the upper end of the transverse rod, and the upper ends of the arc-shaped abutment blocks are in contact with the water pipe located at the left end.

[0013] In summary, this scheme arranges a water pipe between the output port and the input port of the pump body, and the metal joint outside the water pipe is locked to the corresponding output port or input port by threadedly installing a locking hoop sleeve when clamping. At the same time, the two pairs of extended pull rods arranged on the cylindrical L-shaped rod respectively cooperate with the two corresponding locking hoop sleeves, that is, the combined force of the extended pull rod and the horizontal staggered block is used to improve the connection force between the locking hoop sleeve and the pump body, which is beneficial to ensure the tightness of the pump body when transporting wastewater through the water pipe.
