DETAILED DESCRIPTION

[0020] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5The utility model provides a technical solution: a plunger pump with a noise reduction function, including an adsorption mechanism 1, which is embedded and installed in the top center of a base 2, the outer wall of the base 2 is welded to the inner wall of the bottom end of a protective shell 3, and clamping mechanisms 4 are welded on the inner walls of the left and right sides of the protective shell 3. A plunger pump body 5 is tightly fitted on the opposite side of the clamping mechanism 4, a supporting mechanism 6 is sleeved on the driving end of the plunger pump body 5, and a top cover 7 is covered on the top opening of the protective shell 3.

[0022] In this embodiment, Figure 2 and Figure 5 As shown, the adsorption mechanism 1 consists of a vacuum pump 101 and a strong suction cup 102, wherein the vacuum pump 101 is arranged inside the base 2, and the strong suction cup 102 is plugged into the air suction port of the vacuum pump 101; it should be noted that the operator can first put the plunger pump body 5 into the interior of the protective shell 3, and when the bottom of the plunger pump body 5 contacts the base 2, the bottom of the plunger pump body 5 will fit with the strong suction cup 102, and the vacuum pump 101 can be started at this time to extract the air between the plunger pump body 5 and the strong suction cup 102, so that the two form vacuum adsorption, thereby firmly fixing the entire plunger pump body 5 inside the protective shell 3 to prevent it from being strongly vibrated due to excessive internal driving force during operation, causing its position to shift and affect operation, and at the same time, the fixation of the position of the plunger pump body 5 by the adsorption mechanism 1 can enhance its stability during use, thereby avoiding the possibility of collision with other components due to mechanical vibration, thereby reducing the generation of noise.

[0023] In this embodiment, Figure 2 and Figure 3As shown, the clamping mechanism 4 is composed of a buffer spring member 401, a clamping plate 402 and an anti-slip silicone pad 403, wherein one end of the buffer spring member 401 is welded to the inner wall of the protective shell 3, and the other end is welded with a clamping plate 402, and the anti-slip silicone pad 403 is arranged on the inner wall of the recess of the clamping plate 402; it should be noted that when the entire plunger pump body 5 is placed into the interior of the protective shell 3, the outer wall of the plunger pump body 5 will contact the clamping plate 402 in the clamping mechanism 4, and push the clamping plate 402 to both sides, so that the buffer spring member 401 arranged between the clamping plate 402 and the inner wall of the protective shell 3 is squeezed and shortened until the plunger pump body 5 is completely placed into the interior of the protective shell 3, and at the same time, the inner wall of the recess of the clamping plate 402 The wall will contact the plunger pump body 5, and under the rebound and push of the buffer spring part 401, the anti-slip silicone pad 403 arranged on the inner wall of the recessed part of the splint 402 can fit tightly against the outer wall of the plunger pump body 5 to clamp it. When the plunger pump body 5 is used for hydraulic operation, the strong vibration generated by its internal drive will be transmitted through its outer wall to the splint 402 that fits it, and then transmitted to the buffer spring part 401 through the splint 402. At this time, the buffer spring part 401 absorbs and releases the vibration impact force it receives through its own expansion and contraction characteristics, thereby reducing the influence of the vibration impact on the main body of the plunger pump body 5, maintaining its stability during operation, and extending the service life of the entire plunger pump body 5.

[0024] In this embodiment, Figure 1 and Figure 2 As shown, the inner wall interlayer of the protective shell 3 is filled with a sound-absorbing sponge 301; it should be noted that when the plunger pump body 5 is used for hydraulic operation, because its internal driving force is too large, it is easy for the objects inside the plunger pump body 5 to come into contact, thereby generating vibration and generating noise. In the utility model, the entire plunger pump body 5 is placed inside the protective shell 3, and its entire operation process is carried out in the closed protective shell 3. Therefore, the noise generated by the operation of the plunger pump body 5 will be blocked by the protective shell 3, so that it is separated from the outside world, and the sound-absorbing sponge 301 filled in the inner wall interlayer of the protective shell 3 can absorb and scatter sound waves through a large number of pores and cavities inside it at the first time, thereby reducing the propagation and reflection of sound waves, and at the same time, by resonating with the sound waves, the sound waves are converted into heat energy, the energy and intensity of the sound waves are reduced, and the noise generated by the plunger pump body 5 is further reduced.

[0025] In this embodiment, Figure 2 and Figure 5As shown, a shock-absorbing airbag 201 is provided in the inner wall interlayer of the base 2; it should be noted that after the plunger pump body 5 is placed on the top of the base 2 and is adsorbed and fixed by the adsorption mechanism 1, the vibration and noise generated by the plunger pump body 5 during operation can be transmitted to the shock-absorbing airbag 201 provided in the inner wall interlayer through the base 2 and take effect. When the plunger pump body 5 is working, due to its internal structure and the friction between the plunger and the pump chamber, the plunger pump body 5 will generate certain vibrations and noises. When this vibration and noise are transmitted to the shock-absorbing airbag 201 through the base 2, the internal gas will be compressed or expanded by the shock wave, thereby generating a certain pressure change. This pressure change will generate an elastic force similar to a spring, which can offset part of the vibration and noise generated by the plunger pump body 5, and further reduce the noise intensity generated by the plunger pump body 5 during operation.

[0026] In this embodiment, Figure 2 and Figure 4 As shown, the supporting mechanism 6 is composed of an upper sleeve ring 601, a lower sleeve ring 602 and a telescopic rod 603, wherein the inner wall of the lower sleeve ring 602 is sleeved on the outer wall of the driving end of the plunger pump body 5, and its bottom is bonded to the bottom surface of the driving end of the plunger pump body 5, the inner wall of the upper sleeve ring 601 is sleeved on the outer wall of the driving end of the plunger pump body 5 located above the lower sleeve ring 602, and the telescopic rod 603 is arranged between the upper sleeve ring 601 and the lower sleeve ring 602; it should be noted that when the plunger pump body 5 is used, its driving end will be extended or shortened, and at the same time, the upper sleeve ring 601 sleeved on the outer wall of the driving end of the plunger pump body 5 It will be driven to move together, during which time the telescopic rod 603 arranged between the upper ring 601 and the lower ring 602 will also be stretched or compressed. The entire supporting mechanism 6 can always limit the driving end of the plunger pump body 5 to a specified range, thereby ensuring the stability of the driving end of the plunger pump body 5 when it reciprocates. At the same time, the supporting mechanism 6 can also absorb the vibration and shock wave generated by the driving end, reduce the jitter and displacement of the driving end, and avoid contact and collision with other components during operation, thereby reducing the vibration of the plunger pump body 5 and further reducing the noise.

[0027] The use method and advantages of the utility model: When the plunger pump with noise reduction function is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the operator can first open the top cover 7, and then put the plunger pump body 5 into the protective shell 3, the outer wall of the plunger pump body 5 will contact the clamping plate 402 in the clamping mechanism 4, and push the clamping plate 402 to both sides, so that the buffer spring member 401 arranged between the clamping plate 402 and the inner wall of the protective shell 3 is squeezed and shortened, and when the plunger pump body 5 is completely placed in the protective shell 3, the buffer spring member 401 will push the clamping plate 402 in the opposite direction through its rebound property, so that the clamping plate 402 is arranged between the clamping plate 402 and the inner wall of the protective shell 3. The anti-skid silicone pad 403 on the inner wall of the recess can fit tightly against the outer wall of the plunger pump body 5, thereby clamping and fixing the plunger pump body 5. At this time, the bottom of the plunger pump body 5 will fit against the strong suction cup 102 provided on the surface of the base 2. The operator can start the vacuum pump 101 to extract the air between the plunger pump body 5 and the strong suction cup 102, so that the two form a vacuum adsorption, thereby firmly fixing the entire plunger pump body 5 inside the protective shell 3 to prevent it from being caused by excessive internal driving force during operation. The strong vibration causes its position to shift, wherein the buffer spring 401 absorbs and releases the strong vibration generated by the operation of the plunger pump body 5 through its own telescopic characteristics, and when it is sleeved on the plunger pump body 5, at the same time, the upper ring 601 sleeved on the outer wall of the driving end of the plunger pump body 5 will be driven to move together when its driving end is extended or shortened. During this period, the telescopic rod 603 arranged between the upper ring 601 and the lower ring 602 will also be stretched or compressed, so that the entire support The holding mechanism 6 can always confine the driving end of the plunger pump body 5 to a specified range, ensuring the stability of the driving end of the plunger pump body 5 when it reciprocates, and the inner wall interlayer of the base 2 is provided with a shock-absorbing airbag 201 and the inner wall interlayer of the protective shell 3 is filled with a sound-absorbing sponge 301, which can offset part of the vibration and noise generated by the plunger pump body 5 when the plunger pump body 5 generates vibration and noise, and absorb and scatter sound waves, thereby reducing the energy and intensity of the sound waves, and further reducing the noise generated by the plunger pump body 5.
