Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving pumps, and particularly to an energy-saving high-pressure pump. Background Art

[0002] A cleaning machine removes stains by spraying a cleaning liquid onto the surface of an object in a physical or chemical manner to complete the cleaning; in this process, a high-pressure pump is required to transport the cleaning liquid; common high-pressure pumps include plunger pumps and the like.

[0003] For example, Chinese Patent CN221703901U discloses a three-cylinder plunger pump. The plunger pump drives a plunger to move in a cylinder body through a crankshaft and a driving wheel, and through the cooperation of one-way valves, the liquid is transported into the pump body and then output at high pressure to complete the pumping of the liquid.

[0004] However, it is difficult for this plunger pump to individually adjust the flow rate of the pumped liquid according to the usage situation; the existing method for adjusting the flow rate is to keep the one-way valve of a certain cylinder always open, so that the cylinder body does not transport the liquid; but after adjusting the flow rate, the power components of the three cylinders are still running, which is not conducive to energy conservation.

[0005] Based on this, the present invention designs an energy-saving high-pressure pump to solve the above problems. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0038] Embodiment 1: In some embodiments, please refer to the Figures 1 - 4 of the accompanying drawings of the specification. An energy-saving high-pressure pump includes a housing 1, a combined power mechanism 2, a hydraulic mechanism 3, a flow guiding structure 4, and a cooling mechanism 5;

[0039] The water inlet pipe 11 and the water outlet pipe 12 are fixedly installed at the inner top of the housing 1, and three hydraulic mechanisms 3 communicating with the water inlet pipe 11 and the water outlet pipe 12 are installed inside the housing 1; a flow guiding structure 4 is installed inside the hydraulic mechanism 3; a cooling mechanism 5 is installed on the hydraulic mechanism 3;

[0040] A combined power mechanism 2 for driving a hydraulic mechanism 3 is installed on the lower side of a housing 1; the combined power mechanism 2 includes a connection structure 22, a locking assembly 23, a positioning structure 24, a power input shaft 25, and three groups of power components 21. The power components 21 are installed inside the housing 1. The left power component 21 is fixedly connected to one end of the power input shaft 25, and the other end of the power input shaft 25 passes through the housing 1. Two connection structures 22 for connecting adjacent power components 21 are installed inside the housing 1. A locking assembly 23 for locking the connection structure 22 is installed on the housing 1. A positioning structure 24 is installed on the power input shaft 25 and the housing 1.

[0041] In this embodiment, when the energy-saving high-pressure pump is working properly, when the required flow rate is small, multiple groups of power components 21 are not connected. At this time, the power input shaft 25 is connected to an external drive motor, and the drive motor drives the power input shaft 25 to rotate. The power input shaft 25 drives one group of power components 21 to operate, and the power components 21 drive the hydraulic mechanism 3 to operate, so that the liquid flows into the hydraulic mechanism 3 from the water inlet pipe 11, and then is pushed into the water outlet pipe 12 through the hydraulic mechanism 3 to complete the pumping of the liquid. When the required flow rate is large, the left power component 21 is positioned through the positioning structure 24 so that the left power component 21 is in the standard position. The left connection structure 22 is inserted between the power components 21 to connect the left power component 21 to the middle connection structure 22, and then the connection structure 22 is locked by the locking assembly 23. The external motor drives the left power component 21 and the middle power component 21 to operate through the power input shaft 25, thereby driving the left hydraulic mechanism 3 and the middle hydraulic mechanism 3 to operate to achieve the pumping of the liquid. When a larger flow rate is required, the power components 21 are positioned again through the positioning structure 24 so that the left power component 21 and the middle power component 21 are in the standard position. At this time, the right connection structure 22 is inserted between the middle power component 21 and the right power component 21, and the connection structure 22 is locked by the locking assembly 23. At this time, the three groups of power components 21 are connected. The external motor drives the three groups of power components 21 to operate through the power input shaft 25, thereby driving the three groups of hydraulic mechanisms 3 to operate to achieve the pumping of the liquid. Through the cooperation of the power components 21, the connection structure 22, the locking assembly 23, and the positioning structure 24, different numbers of power components 21 can be operated according to the actual working conditions, improving the applicability of the pump.

[0042] During the process of the hydraulic mechanism 3 pumping the liquid, the hydraulic mechanism 3 is cooled by a cooling mechanism 5 to extend the service life of the hydraulic mechanism 3. At the same time, through the setting of the diversion structure 4 inside the hydraulic mechanism 3, while not affecting the hydraulic mechanism 3 pushing the liquid into the water outlet pipe 12, it is possible to avoid sucking part of the liquid in the water outlet pipe 12 while the hydraulic mechanism 3 sucks the liquid in the water inlet pipe 11, thereby effectively reducing energy loss.

[0048] In this embodiment, when the power assembly 21, the connection structure 22, the locking assembly 23, and the positioning structure 24 are working properly, when the required flow rate is small, the power input shaft 25 drives the left shaft body 211 to rotate, and the shaft body 211 drives the eccentric wheel 214 to rotate, thereby driving the hydraulic mechanism 3 to operate through the connecting frame 215; if the required flow rate increases, at this time, the driving member 241 drives the positioning plate 242 to move, and the positioning plate 242 drives the positioning roller 243 to move until the positioning roller 243 contacts the guiding inclined platform 245 on the positioning sleeve 244; the positioning roller 243 drives the positioning sleeve 244 to rotate through the guiding inclined platform 245, and the rotation of the positioning sleeve 244 drives the power input shaft 25 to rotate, thereby driving the left shaft body 211 to rotate; so that the connection groove 216 at the right end of the left shaft body 211 is in the standard position; in the initial state, the positioning block 226 is located in the connection groove 216 on the left side of the middle shaft body 211, so that the middle shaft body 211 is in the standard position; push the adjusting block 221; the adjusting block 221 drives the moving mounting plate 222 to move in the limiting groove 223, thereby driving the connecting shaft 224 and the connecting block 225 to move, so that the connecting blocks 225 on both sides of the connecting shaft 224 are respectively inserted into the connection grooves 216 of the shaft bodies 211 on both sides; lift the rotating block 233 upward so that the locking groove 236 on the lower side of the rotating block 233 disengages from the upper locking block 234, and then rotate the rotating block 233 so that the rotating block 233 moves to a position where it is not blocked by the upper locking block 234, and then move the rotating block 233 and the insertion block 231 downward so that the insertion block 231 vertically moves downward in the insertion slot 232, and the lower side of the insertion block 231 blocks the side of the moving mounting plate 222. At this time, rotate the rotating block 233 so that the locking groove 236 on the lower side of the rotating block 233 is aligned with the lower locking block 235; then continue to move the insertion block 231 and the rotating block 233 downward so that the locking groove 236 is locked on the lower locking block 235 to complete the locking; the rotation of the power input shaft 25 drives the left shaft body 211 to rotate, and the left shaft body 211 drives the middle shaft body 211 to rotate through the connection groove 216, the connecting block 225, and the connecting shaft 224; thereby driving the left hydraulic mechanism 3 and the middle hydraulic mechanism 3 to operate.

[0050] Both ends of the pump pipe 34 are respectively communicated with the water inlet pipe 11 and the water outlet pipe 12.

[0051] The diversion structure 4 includes a diversion sleeve 41. The diversion sleeve 41 is fixedly installed in the pump pipe 34, and the center of the diversion sleeve 41 coincides with that of the pump pipe 34; the diversion sleeve 41 is located on the side of the pump pipe 34 close to the water outlet check valve 36; a central groove 42 is provided in the middle of the diversion sleeve 41; a side groove 43 is formed between the diversion sleeve 41 and the pump pipe 34, and a return groove 44 is provided in the pump pipe 34; the left side of the return groove 44 is straight, and the right side of the return groove 44 is arc-shaped;

[0052] The cooling mechanism 5 includes a first cooling module and a second cooling module. The first cooling module is arranged on the pump pipe 34, and the second cooling module is arranged on the piston rod 31 and the pump pipe 34;

[0053] The first cooling module includes a first check valve 53 and a second check valve 54. A cooling cavity 51 is formed below the piston 32 in the pump pipe 34. Through grooves 58 are symmetrically provided at the bottom of the pump pipe 34, and an external communication flow channel 52 is provided on the pump pipe 34. Both ends of the external communication flow channel 52 are respectively communicated with the two through grooves 58; a first check valve 53 is fixedly installed in one through groove 58, and the second check valve 54 is fixedly installed on the side of the external communication flow channel 52 close to the other through groove 58;

[0054] The second cooling module includes an internal communication flow channel 55. Internal communication flow channels 55 are symmetrically provided on the lower side of the pump pipe 34; one end of the internal communication flow channel 55 is communicated with the through groove 58; a cooling flow channel 56 is provided in the piston rod 31; communication notch openings 57 are provided at both ends of the piston rod 31 where the cooling flow channel 56 is located; the other end of the internal communication flow channel 55 is aligned with the communication notch opening 57.

[0055] The cooling cavity 51, the external communication flow channel 52, the internal communication flow channel 55, the cooling flow channel 56, the communication notch opening 57 and the through groove 58 are filled with a coolant.

[0056] In this embodiment, when the hydraulic mechanism 3, the diversion structure 4 and the cooling mechanism 5 work normally, the shaft body 211 drives the eccentric wheel 214 to rotate, and the eccentric wheel 214 drives the piston rod 31 and the piston 32 to move vertically in the cylinder block 33; when the piston 32 moves vertically downward, the piston 32 generates a negative pressure in the pump pipe 34, and the negative pressure drives the water inlet check valve 35 to move, so that the liquid in the water inlet pipe 11 enters the pump pipe 34; then when the piston 32 moves vertically upward, the liquid pressure pushes the water outlet check valve 36 to open, and the piston 32 pushes the liquid through the central groove 42 and the side groove 43, so that the liquid flows into the water outlet pipe 12 to complete the pumping;

[0057] Then, during the next round of pumping, the piston 32 moves vertically downward. The piston 32 creates a negative pressure inside the pump pipe 34, and the negative pressure drives the opening of the inlet check valve 35. At this time, the outlet check valve 36 gradually closes. Before the outlet check valve 36 is completely closed, the negative pressure inside the pump pipe 34 drives the liquid to flow into the cylinder block 33. At this time, through the settings of the guide sleeve 41, the central groove 42, the side groove 43, and the return groove 44, when the liquid in the outlet pipe 12 flows into the pump pipe 34, part of the liquid is blocked by the middle of the guide sleeve 41, and the liquid in the return groove 44 flows and impacts the liquid in the central groove 42 from the right side of the central groove 42 in the reverse direction. Thus, when the liquid flows from the outlet pipe 12 into the pump pipe 34, an obstruction is formed. Before the outlet check valve 36 is completely closed, an obstruction is formed for the liquid flowing from the outlet pipe 12 into the pump pipe 34, avoiding energy loss.

[0058] During the relative movement of the piston rod 31, the piston 32, and the cylinder block 33, the upward movement of the piston 32 drives the opening of the second check valve 54. When the piston 32 moves downward, the second check valve 54 closes and the first check valve 53 opens. By the reciprocating movement of the piston 32 in the cylinder block 33, the coolant circulates between the cooling cavity 51, the external communication flow channel 52, the internal communication flow channel 55, the cooling flow channel 56, the communication notch 57, and the through groove 58. Through the heat exchange between the coolant in the cooling cavity 51 and the cooling flow channel 56 and the piston rod 31, and then the coolant flows into the external communication flow channel 52 for cooling, thus realizing the cooling of the piston rod 31. During this process, through the setting of the communication notch 57, the internal communication flow channel 55 is always in communication with the cooling flow channel 56, ensuring the circulation of the coolant.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. And these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
