Description

Technical Field

[0001] The invention relates to the technical field of vortex pressure pumps, and in particular to a vortex pressure pump with a detachable noise reduction cover and a use method thereof. Background Art

[0002] A vortex pump (also called an eddy current pump or centrifugal pump) is a common power mechanical pump used to transport liquid from one place to another. It uses centrifugal force to draw in and accelerate the liquid from the inlet, and then discharge it through the outlet. This type of pump is commonly used in a variety of applications, including industries, agriculture, construction, and municipal engineering. The working principle of a vortex pump is based on centrifugal force, which causes the liquid to move in the direction of rotation of the pump. The main components of the pump include rotating parts (such as impellers), fixed parts (such as pump casings), and transmission parts (such as motors or engines). When the motor or engine starts, the rotating parts begin to rotate, sucking in and accelerating the liquid, and then discharging it through the outlet. At present, vortex pumps generate a lot of noise when in use, which seriously affects the working environment of workers. Summary of the invention

[0005] Preferably, a connecting plate is fixedly mounted on the surface of the limit block, a No. 1 screw hole is provided on the side of the base, and a No. 1 bolt is connected to the inner thread of the No. 1 screw hole. Here, the limit block can be fixed in the limit groove by passing the No. 1 bolt through the connecting plate, and it is also convenient for personnel to disassemble and assemble the noise reduction cover.

[0006] Preferably, a No. 2 bolt is inserted into the surface of the hollow plate, and a No. 2 screw hole is opened on the surface of the assembly frame. Here, it is convenient for personnel to disassemble and assemble the hollow plate, so that personnel can replace the sound absorbing layer.

[0007] Preferably, the thickness of the sound absorbing layer is equal to the thickness of the assembly frame, and the bottom surface of the hollow plate fits the surface of the sound absorbing layer. Here, the hollow plate can be used to press the sound absorbing layer tightly to prevent the sound absorbing layer from shaking.

[0008] Preferably, a fan cover is fixedly mounted on the side of the noise reduction cover seat, a fan body is fixedly mounted inside the fan cover, a protective cover is fixedly mounted on the surface of the fan body, and ventilation holes are opened on the surface of the cover body.

[0045] Working principle: When the vortex pump is working, it will generate a lot of noise, which will affect the surrounding environment. At this time, insert the limit block 7 into the limit groove 3 so that the connecting plate 8 can be aligned with the No. 1 screw hole 4, and then pass the No. 1 bolt 5 through the connecting plate 8 and tighten it into the No. 1 screw hole 4, so that the noise reduction cover seat 6 is installed on the bottom plate. The pump body 2 can be surrounded by the cover body 9. At the connection position between the cover body 9 and the pump body 2, the staff will block the noise reduction cover and the vortex pump according to the shape and size of the pump to ensure complete coverage and effective isolation of noise. The handle 10 can be used to facilitate personnel to open the cover body 9 from the surface of the pump body 2 so that personnel can quickly approach the pump body 2 and facilitate personnel to maintain it. When the cover body 9 is opened, the hollow plate 13 can be removed from the surface of the assembly frame 11 by loosening the No. 2 bolt 14 from the No. 2 screw hole 15. In this way, it is convenient for personnel to replace the sound-absorbing layer 12 placed inside the assembly frame 11. When the cover body 9 is opened and placed on the ground, one side of the cover body 9 will come into contact with the ground and cause a collision. By installing a buffer pad 24 on the side of the cover body 9, a violent collision between the cover body 9 and the ground can be avoided, thereby effectively protecting the cover body 9. A damping rod 23 and a spring 25 are arranged between the cover body 9 and the buffer pad 24, which can improve the buffering performance of the buffer pad 24 on the cover body 9. By arranging a fan body 17 on the side of the noise reduction cover seat 6, the pump body 2 inside the cover body 9 can be protected from heat dissipation, so that when the fan body 17 is working, the hot air inside can be quickly discharged to the outside of the noise reduction cover through the ventilation hole 22. The fan body 17 can be protected by the protective cover 18 to prevent external debris from damaging the fan body 17.
