Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pumps, in particular to a high-pressure pump with a solenoid valve type vibration reduction and noise reduction structure. 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

[0007] A further improvement of the high-pressure pump with a solenoid valve type vibration reduction and noise reduction structure of the utility model is that a manual ball valve is further arranged between the connecting pipe and the drainage pipe.

[0008] A further improvement of the high-pressure pump with a solenoid valve type vibration reduction and noise reduction structure of the utility model is that the noise reduction device is arranged at the middle position of the feed pipe between the two connecting pipes.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 3 As shown, a high-pressure pump with a solenoid valve type vibration reduction and noise reduction structure includes a pump body 1, the pump body includes a feed pipe 2 and a discharge pipe 3, two groups of connecting pipes 4 are arranged between the feed pipe and the discharge pipe, a feed check valve 5 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 drainage pipe 6, a connecting pipe 7 is arranged at the lower end of the drainage pipe, a tubular connecting part is arranged on the feed pipe, the connecting pipe is threadedly connected to the connecting part, a solenoid valve 8 is also arranged in the drainage pipe, and the other end of the drainage pipe is connected to a material pool connected to the feed pipe.

[0018] Furthermore, a manual ball valve 9 is provided between the connecting pipe and the drainage pipe.

[0019] The noise reduction device is arranged in the middle of the feed pipe between the two connecting pipes. The inner diameter of the drainage pipe is smaller than the inner diameter of the feed pipe. The connection line of the solenoid valve is linked with the pump body control box.

[0020] The working principle of the utility model is as follows: when the pump body is running, the manual ball valve and the solenoid valve are in a normally open state, and the impact water flow generated by the check water flow and the feed water flow returns to the material pool through the solenoid valve and the drainage pipe. This effectively eliminates the vibration and noise caused by the impact force of the water flow on the pipe wall. The feed system is under positive pressure, and the water flow will continuously overflow through the solenoid valve system on the pump body feed pipe, so when the equipment stops running, the solenoid valve must be in a closed state, which can effectively avoid the overflow of materials. When the solenoid valve fails and cannot be closed, the manual ball valve can be closed to solve this problem. This structural design is ingenious, simple to make, and effectively solves the vibration and noise problems of the equipment. After adopting this mechanism, the equipment is almost vibration-free, and the noise value is reduced from the original 90-95 decibels to 80-84 decibels.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
