Description

Technical Field

[0001] The invention relates to the field of high-pressure cleaning pumps, in particular to a high-pressure cleaning pump. Background Art

[0002] In the prior art, the main hydraulic end assembly of an ultra-high pressure positive displacement pump includes a stuffing box, a plunger seal, an inlet valve box, a valve seat, an inlet and outlet valve core, a discharge valve box and other parts. The high-pressure pump is connected to a water spray pipe, and then the plunger in the high-pressure pump moves back and forth to achieve pressurization of the water flow.

[0003] When the plunger moves, the discharge valve core inside the pump body realizes the unidirectional flow of water in the pump body through the cooperation of the spring, the ball plug and the sealing ring. At the same time, the water flows out at high speed through the rapid movement of the plunger in the high-pressure pump. However, this process requires the reciprocating expansion and contraction of the spring, and the intermittent contact between the ball plug and the sealing ring is achieved through the elastic restoring force of the spring. However, long-term use will cause elastic fatigue of the expansion spring inside the pump body. This will cause the ball plug to be unable to contact the sealing ring when the spring is reset, thereby affecting the normal opening and closing of the pump body, and then affecting the normal flow and pressure control of the fluid inside the high-pressure pump, resulting in leakage of high-pressure fluid, which will not only reduce the efficiency of the pump, but may also cause safety hazards to the working environment and reduce the maintenance cycle of the high-pressure pump.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a compensating distance connecting piece, when the first telescopic spring is elastically fatigued, the ball plug will not be able to contact the sealing ring, and the ball plug will not be able to block the top of the second sleeve. At this time, when the plunger moves, part of the water flow will enter the second sleeve under the impact of the plunger, so that the push rod can drive the annular sleeve to move upward. As the sealing ring moves upward, the sealing ring contacts the ball plug, so that the ball plug can block the inner wall of the sealing ring again. At the same time, the bottom of the ball plug will also contact the top of the second sleeve, so that the water flow stops entering the second sleeve. At the same time, the third telescopic spring is restored, so that the gap between the ball plug and the sealing ring is blocked by the movement of the sealing ring, thereby extending the service life of the equipment and eliminating the need to frequently replace the first telescopic spring.

[0017] 2. By setting a driving connecting piece, when the motor drives the connecting shaft to rotate, the transmission sleeve drives the first turntable to rotate through the hexagonal connecting rod, the second turntable, the locking pin, and the locking hole, so that the driving device inside the pump body can operate. As the sealing ring moves upward, the distance between the second contact piece and the first contact piece becomes closer and closer. When the second contact piece contacts the first contact piece, the electromagnet is energized and operates. At this time, a repulsive force is formed between the electromagnet and the annular magnet block. At this time, the annular magnet block will move away from the electromagnet under the action of the repulsive force, and the locking pin will separate from the locking hole. In this way, the motor cannot drive the first turntable to rotate when it rotates, so that the movement of the plunger can be stopped in time, so as to prevent the first telescopic spring from causing a rapid increase in internal pressure of the pump body due to movement of the plunger when excessive elastic fatigue occurs, thereby improving the safety of equipment use. When the equipment stops spraying or absorbing water, the first telescopic spring can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0029] See also Figures 1 to 8 In an embodiment of the present invention, a high-pressure cleaning pump includes a pump body 1, a pressurizing chamber 2 is installed at one end of the pump body 1, a mounting cover 3 is installed at the end of the pressurizing chamber 2 away from the pump body 1, a connecting chamber 6 is opened inside the pressurizing chamber 2, a plunger 5 is connected to the inside of the pump body 1, a positioning plate 706 is installed on the inner wall of the connecting chamber 6, a guide telescopic rod 707 is installed at the bottom of the positioning plate 706, a ball plug 704 is connected to the bottom end of the guide telescopic rod 707, a first telescopic spring 705 connected to the positioning plate 706 is arranged on the top of the ball plug 704, an annular chamber 701 located below the positioning plate 706 is installed on the inner wall of the connecting chamber 6, a compensation distance connecting piece is arranged on the inner side of the annular chamber 701, and a sealing ring 702 located on the outer side of the ball plug 704 is connected to the top of the annular chamber 701 through the compensation distance connecting piece, a driving connecting piece connected to the internal driving device of the pump body 1 is arranged on the outer wall of the pump body 1, and a connecting shaft 4 is connected to the outer wall of the pump body 1 through the driving connecting piece.

[0030] In this embodiment, when using the device, the output end of the motor is first connected to the connecting shaft 4, and then the operation of the motor causes the connecting shaft 4 to drive the driving device inside the pump body 1 to operate through the driving connecting piece, so that the plunger 5 can move back and forth. At this time, the water flow inside the water inlet pipe will enter the connecting chamber 6 through the annular bin 701 and the sealing ring 702 located below the plunger 5. During this process, the ball plug 704 located below the plunger 5 will move upward under the action of negative pressure. At this time, the first telescopic spring 705 contracts. When the plunger 5 moves toward the connecting chamber 6, the aqueous solution inside the connecting chamber 6 will be discharged through the annular bin 701 and the sealing ring 702 above the plunger 5. The reciprocating movement of the plunger 5 can cause the first telescopic spring 705 to contract repeatedly. When the first telescopic spring 705 is elastically fatigued, the first telescopic spring 705 will The ball plug 704 cannot be driven to move to the initial position, and the ball plug 704 cannot contact the sealing ring 702. At this time, when the plunger 5 reciprocates, the sealing ring 702 will be raised through the compensation distance connecting piece, so that the sealing ring 702 contacts the ball plug 704, so that the ball plug 704 and the sealing ring 702 can once again unidirectionally guide the aqueous solution inside the connecting chamber 6, while also increasing the overall service life of the equipment and reducing the replacement frequency of the first telescopic spring 705. With the use of the equipment, when the first telescopic spring 705 cannot be extended or contracted over a long distance, the driving connecting piece is operated, and the driving device inside the pump body 1 will lose the connection with the external motor, so that the operation of the plunger 5 can be stopped in time, thereby preventing the leakage of high-pressure fluid due to the inability of the ball plug 704 and the sealing ring 702 to seal the solution inside the connecting chamber 6.

[0031] Please refer to Figure 1 , Figure 2 , Figure 4 The inner wall diameter of the sealing ring 702 is smaller than the cross-sectional diameter of the ball plug 704, and the centers of the sealing ring 702 and the ball plug 704 are coaxial.

[0032] In this embodiment, this structure is provided to shield the inner ring of the sealing ring 702 when the ball plug 704 contacts the sealing ring 702 , so that the ball plug 704 can guide the aqueous solution inside the connecting cavity 6 in a unidirectional manner.

[0033] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The distance compensation joint includes an annular sleeve 708 inserted into the annular bin 701, a sealing ring 702 is installed on the top of the annular sleeve 708, a guide tube 709 is provided at the bottom of the annular bin 701, a first sleeve 716 located inside the annular sleeve 708 is installed inside the annular bin 701, the first sleeve 716 is connected to the guide tube 709, a top rod 715 extending to the outside of the positioning plate 706 and connected to the annular sleeve 708 is inserted inside the first sleeve 716, and a second telescopic sleeve connected to the top rod 715 is provided inside the first sleeve 716. Spring 717, a drain pipe 710 is provided at the bottom of the guide pipe 709, a second sleeve 722 located below the ball plug 704 is installed on the top of the guide pipe 709, a second positioning ring 723 is installed on the inner wall of the second sleeve 722, a first positioning ring 721 located below the second positioning ring 723 is installed on the inner wall of the second sleeve 722, a third telescopic spring 720 is provided on the top of the first positioning ring 721, a baffle 718 is installed on the top of the third telescopic spring 720, and a drain pipe 710 is provided on one side of the drain pipe 710 to penetrate to the other side of the drain pipe 710 The rotating shaft 711 is provided with a first transmission bevel gear 712 at both ends of the rotating shaft 711. The rotating shaft 711 and the guide pipe 709 are arranged in a cross-staggered manner. The rotating shaft 711 is provided with a valve plate 719 located inside the discharge pipe 710. The bottom of the annular warehouse 701 is provided with a support warehouse 714 located outside the rotating shaft 711. The rotating shaft 711 is provided with a worm wheel 726 located inside the support warehouse 714. The interior of the support warehouse 714 is connected to a worm 727 meshing with the worm wheel 726. The two ends of the worm 727 are connected to the worm 727. The end extends to the outside of the supporting connecting bin 714, the bottom of the annular bin 701 is connected with the second transmission bevel gear 713 meshing with the first transmission bevel gear 712, the top of the second transmission bevel gear 713 is provided with a ratchet bar 725 located on the inner side of the annular sleeve 708, the inner side of the annular sleeve 708 is provided with a connecting rod 724 arranged side by side with the ratchet bar 725, the bottom end of the connecting rod 724 is rotatably connected with a pawl 728 meshing with the ratchet bar 725 through a rotating shaft, and the connection between the connecting rod 724 and the pawl 728 is clamped with a torsion spring 703 through a slot.

[0034] In this embodiment, when the first telescopic spring 705 drives the ball plug 704 to contact the sealing ring 702, the top of the second sleeve 722 will contact the bottom of the ball plug 704. At this time, when the plunger 5 moves, the water flow cannot enter the second sleeve 722. When the first telescopic spring 705 is elastically fatigued, the ball plug 704 cannot contact the sealing ring 702, and the ball plug 704 cannot block the top of the second sleeve 722. At this time, when the plunger 5 moves, part of the water flow will enter the second sleeve 722 under the impact of the plunger 5. At this time, the spoiler 718 is The second locating ring 723 will be separated from the second locating ring 723 due to the impact of the water flow. At this time, the water flow will enter the first sleeve 716 through the second sleeve 722 and the guide tube 709, so that the top rod 715 can drive the annular sleeve 708 to move upward, so that the sealing ring 702 moves toward the ball plug 704. As the sealing ring 702 moves upward, the sealing ring 702 contacts the ball plug 704, so that the ball plug 704 can block the inner wall of the sealing ring 702 again. At the same time, the bottom of the ball plug 704 will also contact the top of the second sleeve 722, so that the water flow stops entering the second sleeve 72 2, and at the same time, the third telescopic spring 720 is restored, so that the gap between the ball plug 704 and the sealing ring 702 is blocked by the movement of the sealing ring 702, thereby extending the service life of the equipment, and there is no need to frequently replace the first telescopic spring 705. When the sealing ring 702 moves up, the pawl 728 cooperates with the ratchet bar 725 to limit the sealing ring 702 in one direction, so that the sealing ring 702 can be prevented from moving downward relative to the annular chamber 701. When the first telescopic spring 705 is replaced, the worm 727 can be rotated by screwing it with a screwdriver, and the sealing ring 702 can be replaced by screwing it with a screwdriver. The worm 727 drives the worm wheel 726 to rotate so that the valve plate 719 loses its cover on the bottom of the guide tube 709. At the same time, the first transmission bevel gear 712 and the second transmission bevel gear 713 cooperate to make the slot of the ratchet bar 725 and the pawl 728 misaligned. At this time, the annular sleeve 708 will move downward under the elastic restoring force of the second telescopic spring 717, so that the aqueous solution inside the first sleeve 716 can be discharged through the drain pipe 710. After that, it can be found that the worm 727 can be turned to restore the valve plate 719 and the ratchet bar 725, which is convenient for the use of subsequent equipment.

[0035] Please refer to Figure 4 , Figure 5 There are two ratchet bars 725 and two first sleeves 716, and the two ratchet bars 725 and the first sleeves 716 are arranged in a cross-like manner.

[0036] In this embodiment, this structure is provided to increase the stability of the movement of the annular sleeve 708 and the sealing ring 702 .

[0037] Please refer to Figure 4The sealing ring 702 , the annular sleeve 708 , the annular bin 701 , and the second sleeve 722 are coaxial, and the top curvature of the second sleeve 722 is equal to the bottom curvature of the ball plug 704 .

[0038] In this embodiment, this structure is provided to shield the top of the second sleeve 722 when the ball plunger 704 is restored, and at the same time, the accuracy of the docking between the bottom of the ball plunger 704 and the top of the second sleeve 722 is improved.

[0039] Please refer to Figure 5 The diameter of the spoiler 718 is larger than the inner wall diameter of the second positioning ring 723 and smaller than the outer wall diameter of the second positioning ring 723 .

[0040] In this embodiment, this structure is provided to prevent the spoiler 718 from completely blocking the second sleeve 722 , so that when the spoiler 718 is separated from the second positioning ring 723 , water flows into the guide tube 709 through the inner side of the second positioning ring 723 and the first positioning ring 721 .

[0041] Please refer to Figure 1 , Figure 4 , Figure 7 , Figure 8 The driving connecting member includes a positioning cylinder 802 installed on the inner wall of the connecting chamber 6 and located above the sealing ring 702, a plug rod 803 extending to the inner side of the positioning cylinder 802 is installed on the top of the sealing ring 702, a second contact piece 805 located inside the positioning cylinder 802 is installed on the top of the plug rod 803, a first contact piece 804 located above the second contact piece 805 is installed on the inner wall of the positioning cylinder 802, a positioning frame 801 is installed on the outer side of the pump body 1, a first rotating disk 807 is rotatably connected to the inner side of the positioning frame 801 through a bearing, the first rotating disk 807 is connected to the driving device inside the pump body 1 through a rotating shaft, a locking hole 813 is opened on the first rotating disk 807, and a first contact piece 805 is installed on the inner side of the positioning frame 801. The electromagnet 808 around the turntable 807, the end of the positioning frame 801 away from the pump body 1 is rotatably connected to the transmission sleeve 812 through a bearing, the connecting shaft 4 is connected to the transmission sleeve 812, and the fourth telescopic spring 806 is installed inside the transmission sleeve 812, one end of the fourth telescopic spring 806 is connected to the limiting plate 815, and the limiting plate 815 is installed with a hexagonal connecting rod 811 extending to the outside of the transmission sleeve 812, and the second turntable 810 is installed at the end of the hexagonal connecting rod 811 close to the first turntable 807, and the outer side of the second turntable 810 is provided with an annular magnet block 809, and the end of the second turntable 810 close to the first turntable 807 is installed with a locking pin 814 extending to the inside of the locking hole 813.

[0042] In this embodiment, when the motor drives the connecting shaft 4 to rotate, the transmission sleeve 812 drives the first rotating disk 807 to rotate through the hexagonal connecting rod 811, the second rotating disk 810, the locking pin 814, and the locking hole 813, so as to operate the driving device inside the pump body 1. As the sealing ring 702 moves upward, the second contact piece 805 is closer and closer to the first contact piece 804. When the second contact piece 805 contacts the first contact piece 804, the electromagnet 808 is energized and operates, and a repulsion is formed between the electromagnet 808 and the annular magnet block 809. At this time, the annular magnet block 809 will be away from the electromagnet 808 under the action of the repulsive force, and the locking pin 814 will be separated from the locking hole 813, so that the motor cannot drive the first turntable 807 to rotate when it rotates, so that the movement of the plunger 5 can be stopped in time, so as to prevent the first telescopic spring 705 from causing excessive elastic fatigue and causing the internal pressure of the pump body 1 to increase rapidly due to movement, thereby improving the safety of the equipment. When the equipment stops spraying or absorbing water, the first telescopic spring 705 can be replaced.

[0043] Please refer to Figure 4 , Figure 8 The first contact piece 804 is electrically connected to the electromagnet 808 through a wire, and the second contact piece 805 is electrically connected to an external power source through a wire.

[0044] In this embodiment, by providing this structure, the electromagnet 808 is energized and operated when the second contact piece 805 contacts the first contact piece 804, thereby controlling the operation time of the electromagnet 808.

[0045] Please refer to Figure 8 One end of the locking pin 814 away from the second rotating disk 810 is rotatably connected to a ball through a rotating shaft, and the diameter of the locking hole 813 is equal to that of the locking pin 814.

[0046] In this embodiment, when the electromagnet 808 is powered off, the annular magnet block 809 will restore under the action of the elastic restoring force of the fourth telescopic spring 806. If the locking hole 813 and the locking pin 814 are not aligned, the locking pin 814 will rotate along the first turntable 807 when the connecting shaft 4 rotates, and the friction between the first turntable 807 and the locking pin 814 is reduced by the ball at one end of the locking pin 814.

[0047] Please refer to Figure 8 When the locking pin 814 is inserted into the locking hole 813, the distance between the electromagnet 808 and the annular magnet block 809 is five millimeters.
