Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pumps, in particular to a floating ball type vibration reduction and noise reduction mechanism for high-pressure pumps. Background Art

[0002] like Figure 1 As shown, during the operation of the existing high-pressure pump, the valve core of the feed check valve on one side is in an open state, and the valve core of the feed check valve on the other side is in a non-return state. The feed water flow and the non-return water flow collide and impact each other in the pipe, which will cause the pipe body to vibrate and produce a high-decibel noise of 90-95. The conventional method to solve the noise and vibration is to use an accumulator and a water hammer eliminator at the feed end, but because the material is not water, but sewage containing particulate matter, it will damage the accumulator and the water hammer eliminator, and the use effect cannot be achieved.

[0003] In order to solve the noise problem, the existing Chinese utility model patent with application number 202222962562.7 discloses a high-pressure single-feed pump body with a noise reduction device, which sets a tank on the pipeline to achieve noise reduction; however, this method of installing an ordinary pressure-stabilizing tank on the pipeline, after a period of operation, the air in the tank is compressed by the material, and the effect of vibration reduction and noise reduction cannot be achieved. The material in the tank can only be discharged manually, which affects the normal operation of production. Utility Model Content

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Such as Figure 1 And Figure 2As shown in the figure, a floating ball type vibration reduction and noise reduction mechanism for a high-pressure pump includes a pump body 1, on which a feed pipe 2 and a discharge pipe 3 are provided. There are two groups of connecting pipes between the feed pipe and the discharge pipe. A feed check valve 4 is arranged in the connecting pipe. A noise reduction device is arranged on the feed pipe between the two groups of connecting pipes. The noise reduction device includes a tank body 5 and an air pipeline 10. The air pipeline passes through the tank body and abuts against a perforation formed on the tank body to achieve sealing. Both ends of the air pipeline are respectively located inside and outside the tank body. A floating ball 11 is arranged inside the tank body, and the floating ball is used to block the end of the air pipeline located inside the tank body.

[0018] Furthermore, a fixed pipe 6 is formed on the feed pipe, and a connecting flange 7 is arranged on the fixed pipe. A second connecting flange 9 is arranged on the lower part of the tank body through a second fixed pipe 8. The tank body and the feed pipe are connected by fasteners at the connecting flange and the second connecting flange.

[0019] Furthermore, the end of the air pipeline located inside the tank body is arranged vertically downward, and the floating ball is arranged directly below it. The end of the air pipeline located inside the tank body is close to the second fixed pipe, and the floating ball is arranged inside the second fixed pipe.

[0020] Preferably, the noise reduction device is arranged at the middle position of the feed pipe between the two groups of connecting pipes.

[0021] The working principle of the present utility model is as follows: When the pump body is feeding, the material inside the mechanism is sucked away, the liquid level drops, the floating ball is in an open state, and air enters the tank body through the intake pipeline. When the water flow impact generated when the check valve spool checks returns enters the tank body of the mechanism, due to the rise of the liquid level, the floating ball closes, so that the material cannot go out from the intake pipeline. In this way, the effects of reducing vibration and noise are achieved. After actual measurement, after adopting this mechanism, the equipment has almost no vibration, and the noise value is reduced from the original 90 - 95 decibels to 80 - 84 decibels.
