[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1 - Figure 6 , the present application provides a shock-absorbing chemical pump body, comprising:

[0037] The pump body 100 has a pump head 101 on the left side of the pump body 100, and a pump frame 102 is provided at the bottom of the pump body 100. The bottom of the pump frame 102 is provided with bolt holes for easy installation on the mounting surface. A shock absorber is additionally provided between the pump frame 102 and the mounting surface to achieve a shock-absorbing effect.

[0038] The pump shaft 103 is installed inside the pump body 100, with a bearing embedded therebetween;

[0039] And a guide vibration reduction mechanism 300 installed on the left side of the pump head 101 to guide the inlet flow. The guide vibration reduction mechanism 300 can be used to guide and comb the sucked water flow, so that the water flow will not have vortices or wall vortexes, and thus will not be cut by the pump impeller 105 to generate vibration, thereby having a shock-absorbing effect on the entire chemical pump. At the same time, it can reduce the instantaneous impact and pressure of the sucked water flow on the pump impeller 105, reduce the loss and vibration of the instantaneous impact, and increase the stability of the entire chemical pump. The guide vibration reduction mechanism 300 includes an inlet pipe 301 installed on the left side of the pump head 101, a guide member 302 installed at the left end of the pump shaft 103, a rectifying member 304 for rectifying the water flow entering the pump head 101, and a cleaning member 303 for filtering and cleaning the water flow entering the pump head 101;

[0040] The flow guide component 302 includes an outer flow guide plate 3021 located inside the water inlet pipe 301 , a fixing ring 3032 , and a guide cylindrical cam 3024 and a guide rod 3025 for driving the outer flow guide plate 3021 and the inner flow guide plate 3022 to move.

[0041] In this embodiment, preferably, a connecting block is provided between the outer guide plate 3021 and the inner guide plate 3022 to achieve synchronous movement of the two, and the outer guide plate 3021 and the inner guide plate 3022 are inclined to reduce the resistance to the suction water flow. At the same time, the outer guide plate 3021 and the inner guide plate 3022 are staggered up and down to facilitate filling the entire water inlet pipe 301. The water inlet pipe 301 is composed of a horizontal pipe and a tapered pipe, and rectangular holes for water flow to pass through are opened on the surface of both. To affect the flow of water, the rectangular holes on the outer guide plate 3021 and the inner guide plate 3022 can be overlapped or vertical, which can not only straighten and comb the water flow, but also play a certain role in filtering and removing impurities from the water flow. The inner wall of the water inlet pipe 301 is provided with two guide limit plates 3023 that guide the inner guide plate 3022 and the outer guide plate 3021. The two guide limit plates 3023 respectively cooperate with the notches opened at the upper and lower ends of the inner guide plate 3022 and the outer guide plate 3021.

[0042] In this embodiment, preferably, a guide cylindrical cam 3024 is provided at the left end of the pump shaft 103, and a support ring 3027 is provided at the left end of the guide cylindrical cam 3024, and the two are rotatably connected without affecting the rotation of the guide cylindrical cam 3024. The support ring 3027 is fixed to the inner wall of the water inlet pipe 301 through an extension plate provided on the surface. A guide groove is provided on the surface of the guide cylindrical cam 3024, and a guide rod 3025 is provided on the inner surface of the inner guide plate 3022. The other end of the guide rod 3025 extends into the guide groove, and the water inlet pipe 3 01 The inner wall is provided with a stabilizing block 3026 supporting the guide rod 3025. The stabilizing block 3026 can guide the guide rod 3025. As the guide cylindrical cam 3024 rotates, it can drive the guide rod 3025 to move left and right in the guide groove, drive the outer guide plate 3021 and the inner guide plate 3022 to move, actively meet the incoming water flow, intensify the reverse driving of the water flow, increase the diversion and combing effect of the water flow vortex, make the vortex disappear quickly, thereby reducing the vibration between the vortex and the pump impeller 105.

[0043] In this embodiment, preferably, the rectifying member 304 is sleeved on the pump shaft 103 and is located inside the guide member 302. The rectifying member 304 can be used to rectify and guide the water flow entering the impeller chamber after reducing the impact force of the suction water flow on the pump impeller 105, thereby increasing the water flow velocity and reducing the cavitation vibration of the water flow. The rectifying member 304 includes a collar 3041 sleeved on the pump shaft 103, and the front and rear surfaces of the collar 3041 are provided with a support rod 3 fixed to the inner wall of the water inlet pipe 301. 042. A plurality of guide ramps 3043 are obliquely arranged on the support rod 3042. Two intermediate guide plates 3044 are symmetrically arranged on the upper and lower surfaces of the collar 3041. Guide wheels 3045 are rotatably arranged on the free ends of the intermediate guide plates 3044 and the upper and lower ends of the guide ramps 3043. The guide ramps 3043 and the intermediate guide plates 3044 are all obliquely distributed. The guide wheels 3045, the guide ramps 3043 and the intermediate guide plates 3044 play a role in guiding and rectifying the water flow passing through.

[0044] In summary, when in use, the pump shaft 103 rotates to drive the guide cylindrical cam 3024 to rotate, driving the guide rod 3025 to move in the guide groove, thereby driving the outer guide plate 3021 and the inner guide plate 3022 connected to the guide rod 3025 to move. When the movement direction of the outer guide plate 3021 and the inner guide plate 3022 is opposite to the direction of the water flow entering the water inlet pipe 301, the reverse movement of the guide plate increases the resistance to the incoming water flow and the diversion effect, so that the water flow in a vortex state gradually enters the pump impeller 105 smoothly, reducing the vibration caused by the vortex water flow being cut by the pump impeller 105. At the same time, the moving guide plate can slow down the flow rate of the water flow, and reduce the flow rate without affecting the normal suction flow rate range of the water flow. The instantaneous impact of water flow on the pump impeller 105 is reduced, thereby reducing the vibration caused by the impact and the transmission of vibration, thereby reducing the shock of the entire chemical pump. The water after diversion passes through the guide wheel 3045, the middle guide plate 3044 and the guide inclined plate 3043 to further sort out the diversion, and the water flows through the guide wheel 3045 to rotate. The rotating guide wheel 3045 has a driving effect on the movement of the water flow, and has a certain pressurization and rectification effect on the water flow entering the pump head 101. Moreover, this rectification pressure is smaller than that of the water flow directly impacting the pump impeller 105, and does not conflict with the buffering of the water flow by the guide plate. The rectification of the guide wheel 3045 reduces cavitation vibration, thereby reducing the vibration of the entire chemical pump. Multiple functions increase the working stability of the chemical pump.

[0045] Example 2

[0046] Reference Figure 7 , which is the second embodiment of the present invention.

[0047] In this embodiment, preferably, the cleaning member 303 includes a fixed ring 3032 sleeved on the pump shaft 103 and a collecting ring 3033 installed on the left side of the pump head 101. The cleaning member 303 can be used to further filter and collect impurities in the water before the water is sucked into the pump head 101, so as to prevent impurities from directly entering the pump impeller 105 and causing blockage, thereby reducing the vibration transmission caused by the blockage and reducing the vibration of the pump body as a whole. A conical cleaning ring 3033 is provided between the inner surface of the collecting ring 3032 and the fixed ring 3032. Cover 3031, the conical cleaning cover 3031 is located outside the water suction port of the pump head 101, and an annular groove is provided on the front surface of the collecting ring 3033. The conical cleaning cover 3031 is a filter cover and does not affect the flow of water. The shape of the conical cleaning cover 3031 allows the impurities retained on the outer surface of the conical cleaning cover 3031 to be washed into the annular groove along the inclined surface by the water flow and collected, and a plurality of reinforcement rods 3034 are provided on the circumference of the inner surface of the conical cleaning cover 3031. The reinforcement rods 3034 support and reinforce the conical cleaning cover 3031.

[0048] In summary, when in use, the inhaled water passes through the conical cleaning cover 3031, and the impurities mixed in the water are retained on the outer surface of the conical cleaning cover 3031, and the filtered water continues to enter the pump head 101 and is rotated and transported by the pump impeller 105. As the water flow is continuously inhaled, the impurities retained on the outer surface of the conical cleaning cover 3031 are blown along the inclined surface and enter the annular groove on the surface of the collecting ring 3033, thereby increasing the stability of water flow suction, and preventing the impurities from being sucked in and colliding with the pump impeller 105 to cause loss, and at the same time, preventing impurity blockage, reducing the vibration caused by blockage and collision, thereby reducing the transmission of vibration, and having a shock-absorbing effect on the entire chemical pump body.

[0049] Example 3

[0050] Reference Figure 8 and Figure 9 , which is the third embodiment of the present invention.

[0051] In this embodiment, preferably, a connecting frame 104 is provided between the pump body 100 and the pump head 101, and a shaft vibration-damping component 200 located inside the connecting frame 104 is sleeved on the pump shaft 103. The shaft vibration-damping component 200 can be used to further support and stabilize the pump shaft 103, increase the number of supports for the pump shaft 103 and reduce the support spacing, thereby reducing the factors of eccentric vibration of the pump shaft 103, and at the same time lubricate and clean the connection between the pump shaft 103 and the bearing, reduce the gap vibration caused by wear, reduce vibration transmission, and reduce the overall vibration of the chemical pump. The shaft vibration-damping component 200 includes a shaft fixed to the inner surface of the connecting frame 104 and sleeved on the pump shaft. The mounting ring 201 on 103 has a plurality of supporting spherical parts 202 for supporting the pump shaft 103 arranged on the inner circumference of the mounting ring 201. An oil ring 204 for lubricating the connection between the pump shaft 103 and the bearing is arranged on the right side of the mounting ring 201. A hollow annular cavity is provided inside the oil ring 204, and an oil hole communicating with the annular cavity is provided on the inner surface of the oil ring 204 to facilitate the entry of oil into the adsorption layer 205. An oil filling hole is provided on the rear surface of the oil ring 204, which can be connected to the external oil filling system. An adsorption layer 205 is provided on the inner surface of the oil ring 204. The adsorption layer 205 can be a thick cotton layer, which can absorb the lubricating oil and can be discharged by squeezing.

[0052] In this embodiment, preferably, a fixed cylindrical cam 203 is provided on the left side of the adsorption layer 205, which is sleeved on the pump shaft 103. The fixed cylindrical cam 203 can rotate with the pump shaft 103. A ball head rod 208 is provided on the left side of the oil ring 204 to cooperate with the fixed cylindrical cam 203. Two telescopic columns 206 are provided between the left side of the oil ring 204 and the mounting ring 201. The telescopic columns 206 are symmetrically distributed on the outside of the pump shaft 103. A reset member 207 is provided on the telescopic column 206 to facilitate driving. The mounting ring 201 is moved and reset, and a spherical sleeve 2021 is provided on the outside of the supporting ball part 202. The supporting ball part 202 can rotate in the spherical sleeve 2021 without affecting the rotation of the pump shaft 103, reducing the wear of the contact between the two. The outer surface of the spherical sleeve 2021 is provided with an adjusting rod 2022 threadedly connected to the mounting ring 201. Rotating the adjusting rod 2022 can change the position of the supporting ball part 202, which is convenient for changing the space between several supporting ball parts 202 for the pump shaft 103 to pass through.

[0053] In summary, when in use, according to the size of the pump shaft 103, hold the adjustment rod 2022 and rotate it, driving the spherical sleeve 2021 and the supporting ball member 202 to move toward the pump shaft 103 until the supporting ball member 202 contacts the surface of the pump shaft 103. The same operation is taken to allow multiple supporting ball members 202 to contact the surface of the pump shaft 103 at the same time. Multiple supporting ball members 202 support the pump shaft 103 without affecting the rotation of the pump shaft 103. Multiple supporting points can be set in the empty space of the pump shaft 103 to reduce the axis spacing, thereby reducing the pump shaft 103. In the case of eccentric vibration, the rotation of the pump shaft 103 will cause the fixed cylindrical cam 203 to rotate. The raised part of the right end of the fixed cylindrical cam 203 cooperates with the ball rod 208, driving the ball rod 208 to move along the pump shaft 103, driving the mounting ring 201 and the adsorption layer 205 to move. When the mounting ring 201 does not move, the adsorption layer 205 on the right side is not squeezed and is located on the side of the bearing. The gap between the two is very small, which reduces the entry of impurities into the connection between the bearing and the pump shaft 103, and the distance the mounting ring 201 moves can squeeze the adsorption layer 205. 05. When the adsorption layer 205 moves to the connection between the pump shaft 103 and the bearing, one end of the adsorption layer 205 can extend a part, and the lubricating oil adsorbed inside will seep out and flow to the connection due to the pressure from the side of the bearing, thereby lubricating the connection, reducing friction and reducing the gap vibration caused by friction. Moreover, the adsorption layer 205 does not rotate while the pump shaft 103 rotates. The adsorption layer 205 can clean the pump shaft 103 and reduce the entry of foreign particles into the connection between the pump shaft 103 and the bearing. When the mounting ring 201 moves to the right, the telescopic column 206 moves with The mounting ring 201 moves and extends, and the reset member 207 stretches. When the raised portion of the fixed cylindrical cam 203 has no restriction on the ball head rod 208, the reset member 207 recovers its elasticity, driving the mounting ring 201 to move to the left, reducing the squeeze on the adsorption layer 205. The entire shaft vibration-damping component 200 can support and reinforce the pump shaft 103, reduce eccentric vibration, and lubricate and clean the connection between the pump shaft 103 and the bearing, reduce wear and tear gaps, thereby reducing the vibration of the pump shaft 103 and the bearing, reducing vibration transmission, and thus reducing the vibration of the entire chemical pump.

[0054] Example 4

[0055] This embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment.

[0056] When in use, the shaft vibration-damping component 200 always supports, reinforces, lubricates and cleans the rotating pump shaft 103, reduces the wear gap between the pump shaft 103 and the bearing, reduces vibration transmission, and at the same time, guides and rectifies the inhaled water vortex, reduces the vibration generated by the cutting of the water vortex and the pump impeller 105, thereby playing a shock-absorbing role for the entire chemical pump.

[0057] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
