[0002] A reciprocating pump is a conveying machine that directly provides energy to the liquid in the form of pressure energy through the reciprocating motion of the piston. It is an important fluid conveying equipment. The working principle of a reciprocating pump is based on the reciprocating motion of the piston in the pump cylinder. The liquid is sucked in and discharged by changing the volume in the pump cylinder. Reciprocating pumps can be divided into piston pumps, metering pumps, diaphragm pumps, etc.

[0003] Generally, there is a certain amount of lubricating oil inside the reciprocating pump case, but the parts that need lubrication at high places inside the case are difficult to access the lubricating oil. At this time, the lubricating oil needs to be sent to a high place for lubrication. The traditional equipment mechanism lubrication method is to use an oil pump motor to send the lubricating oil to the parts that need lubrication through complex and cumbersome internal pipelines. Not only does it require an additional motor as power to transport the lubricating oil, but it also requires the installation of complex lubricating oil pipelines, which need to be bent and fixed, etc., which increases the size of the equipment and wastes more space. In addition, the amount of lubricating oil inside the reciprocating pump case is easily mixed with impurities such as parts debris, which can easily cause blockage problems in oil pipelines, etc., and the lubrication effect is poor.

[0004] To this end, a reciprocating pump with a spiral oil delivery lubrication structure is proposed. Summary of the invention

[0023] As an embodiment of the present invention, Figure 1 and Figure 2 as well as Figure 5As shown, the continuous oil delivery mechanism includes an oil delivery channel 7 opened inside the worm 4, oil outlet holes 8 penetrating the worm 4 are opened on both sides of the oil delivery channel 7, an oil delivery screw 9 is arranged inside the oil delivery channel 7, and a rectangular thread groove 10 is arranged on the outer surface of the oil delivery screw 9. The inner diameter of the oil delivery channel 7 is larger than the diameter of the oil delivery screw 9, and a gap is arranged between the inner wall of the oil delivery channel 7 and the outer side of the oil delivery screw 9. When in use, because there is a gap between the oil delivery channel 7 inside the worm 4 and the outer side of the oil delivery screw 9, and the outer side of the oil delivery screw 9 is provided with a rectangular thread groove 10, the rotation of the worm 4 is brought about by the oil delivery channel 7 inside the worm 4. The lubricating oil inside the moving box 1 is transported to the high oil outlet hole 8 along the rectangular thread groove 10 on the outer side of the oil delivery screw 9, and then is sent to the top of the bearing part 5 through the oil outlet hole 8 to lubricate the bearing part 5, thereby ensuring the rotation effect of the worm 4. It is beneficial to use the power of the rotation of the worm 4 to automatically transport the lubricating oil upward to lubricate the high-position bearing part 5. It not only cleverly borrows the power of the equipment itself without setting up an additional power source, thereby achieving energy conservation and emission reduction, and reducing costs, but also reduces the number and volume of equipment, thereby achieving convenient installation and maintenance, high reliability, and space saving.

[0024] As an embodiment of the present invention, Figures 1 to 5 As shown, the pressurized drainage mechanism includes a base 11 threadedly connected to the bottom end of the oil delivery screw 9, the base 11 is connected to the oil delivery screw 9 as a whole, the oil delivery screw 9 cannot rotate, the base 11 is arranged on the support 2, a transmission cavity 12 and an oil inlet 13 are provided inside the base 11, a propeller 21 is provided at the middle of the top of the oil inlet 13, an oil delivery channel 14 is provided at the top of the base 11, the oil delivery channel 14 extends to the upper end of the base 11, a filter screen 15 is inlaid at the bottom end of the oil inlet 13, the filter screen 15 is arranged in a circular shape, the oil inlet 13 is arranged in a truncated cone shape, the upper port diameter of the oil inlet 13 is smaller than the lower port diameter, the continuous oil delivery mechanism drives the propeller 21 to rotate, and the propeller 21 has a certain effect on the lubricating oil entering the base 11. The increased pressure can make the lubricating fluid rise better along the rectangular thread groove 10, and then filter the lubricating oil into the base 11 through the filter 15 to remove the debris and impurities mixed in the lubricating oil. Finally, the oil is drained through the inner cone structure of the oil inlet 13 to accelerate the flow rate of the upper lubricating oil into the oil delivery channel 14, so that it quickly enters the rectangular thread groove 10, which is conducive to setting the propeller 13 for supercharging, increasing the conveying speed, reducing the influence of the lubricating oil's own weight on the conveying, greatly ensuring the conveying effect, and draining through the unique structure of the base 11 to further improve the conveying effect. At the same time, the base 11 can also filter the incoming lubricating oil to avoid clogging of the rectangular thread groove 10.

[0025] As an embodiment of the present invention, Figures 1 to 5As shown, the bottom end of the worm 4 is fixedly connected with an inner gear ring 16, and a gear 17 is meshed inside the inner gear ring 16. The bottom end of the gear 17 is inserted into the transmission cavity 12 through a round rod and is fixedly connected with a first pulley 18. The first pulley 18 is rotatably connected to the bottom end of the transmission cavity 12. The first pulley 18 is connected to the second pulley 20 through a belt 19. The bottom end of the second pulley 20 passes through the base 11 through a round rod and is fixedly connected with a propeller 21. The diameter of the first pulley 18 is larger than the diameter of the second pulley 20. The first pulley 18 and the second pulley 20 are connected to the bottom end of the transmission cavity 12. On the same plane, the worm 4 drives the inner gear ring 16 to rotate. Because the inner gear ring 16 meshes with the gear 17, the inner gear ring 16 drives the gear 17 to accelerate the rotation. Then the gear 17 drives the first pulley 18 to rotate. The first pulley 18 transmits the second pulley 20 through the belt 19. The propeller 21 is fixedly connected to the bottom end of the second pulley 20. Therefore, the worm 4 can drive the propeller 21 to accelerate the rotation, which is beneficial to use the power of the worm 4 to accelerate the rotation of the propeller 21 multiple times, so that the lubricating oil in the base 11 can be further pressurized to improve the drainage effect.

[0026] Working principle: When in use, because there is a gap between the oil delivery channel 7 inside the worm 4 and the outer side of the oil delivery screw 9, and a rectangular thread groove 10 is provided on the outer side of the oil delivery screw 9, the rotation of the worm 4 drives the lubricating oil inside the box 1 to be transported to the high-position oil outlet hole 8 along the rectangular thread groove 10 on the outer side of the oil delivery screw 9, and then is sent to the upper side of the bearing 5 through the oil outlet hole 8 to lubricate the bearing 5, thereby ensuring the rotation effect of the worm 4; The continuous oil delivery mechanism drives the propeller 21 to rotate, and the propeller 21 pressurizes the lubricating oil entering the base 11. The increased pressure can make the lubricating liquid rise better along the rectangular thread groove 10, and then filter the lubricating oil entering the base 11 through the filter 15 to remove the debris and impurities mixed in the lubricating oil. Finally, the lubricating oil is drained through the inner cone structure of the oil inlet 13, so that the flow rate of the upper end lubricating oil is accelerated to enter the oil delivery channel 14, so as to quickly enter the rectangular thread groove 10; The worm 4 drives the inner gear ring 16 to rotate. Because the inner gear ring 16 meshes with the gear 17, the inner gear ring 16 drives the gear 17 to rotate faster. Then the gear 17 drives the first pulley 18 to rotate. The first pulley 18 transmits the second pulley 20 through the belt 19. The propeller 21 is fixedly connected to the bottom end of the second pulley 20, so the worm 4 can drive the propeller 21 to rotate faster.
