Description

Technical Field

[0001] The invention belongs to the technical field of reciprocating plunger pumps, and in particular relates to a forced lubrication reciprocating plunger pump. Background Art

[0002] A packing seal is generally used between the plunger and the stuffing box of a plunger pump. Long-term high-speed operation will cause dry friction due to the lack of lubricating medium between the plunger and the packing. The friction will increase the plunger temperature, thereby increasing the energy consumption of the pump and reducing the pump efficiency. Continuous temperature increase will shorten the service life of the plunger and seals and increase the consumption of wearing parts. In order to extend the life of wearing parts such as the hydraulic end plunger, lubricating oil or grease must be added to enable the plunger and packing to achieve better operating conditions.

[0003] For example, a reciprocating plunger pump plunger lubrication system with application number 202311579070.2 realizes automatic lubrication, but this lubrication method has defects, such as easy blockage of pipelines and damage to electronic circuits, which will lead to lubrication failure, so a forced lubrication mechanism needs to be added. This phenomenon has become a problem that needs to be solved urgently by people in this field. Summary of the invention

[0007] The present invention further illustrates that a wheel disc is installed on the inner wall bearing of the forced lubrication cavity, and a spiral spring is arranged at the bearing; a balance rod is fixedly installed in the middle of the wheel disc, the lower end of the balance rod is magnetic, the upper end of the balance rod is in contact with the outer surface of the arc block, and the lower end of the balance rod is in contact with the left side of the hydraulic cavity; the bottom spring of the hydraulic cavity is connected to a magnetic block, and the magnetic block is aligned with the lower end of the balance rod, and the magnetic poles of the two are opposite; a shaking plate is fixed to the right side of the magnetic block.

[0008] The present invention further describes that a circular arc rod is fixedly installed on the left side of the lower end of the balance rod, and a striking rod is fixedly installed on the upper end of the discharge pipe; the outer end of the circular arc rod and the upper end of the striking rod are both spherical.

[0009] The present invention further illustrates that the steps of forced lubrication include: step S1, the operator manually shakes the rocker counterclockwise; step S2, the arc block and the hydraulic rod contact and squeeze each other, the lubricating oil enters the drain pipe through the pipeline, and then is discharged from the drain pipe into the reciprocating plunger mechanism for lubrication, and then the rocker is shaken in the reverse direction for secondary lubrication until the rocker is reset; step S3, the lubrication work is completed.

After the rocker is reset, the lower end of the balance bar is reset, and the magnetic attraction generated by the magnetic block pulls the magnetic block upward and resets again. The lubricating oil can be shaken during each forced lubrication to fully prevent the precipitate from entering the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The present invention provides a technical solution: a forced lubrication reciprocating piston pump, comprising a base 1, an engine 2 is fixedly installed on the upper left side of the base 1, a cylinder 3 is fixedly installed on the upper right side of the base 1, a reciprocating piston mechanism is arranged inside the cylinder 3, and a turntable 4 is connected to the output end of the reciprocating piston mechanism;

[0024] A connection plate 5 is fixed to the output end of the engine 2, and the connection plate 5 is connected to the track of the turntable 4. A forced lubrication chamber 6 is fixedly installed above the cylinder body 3;

[0025] The forced lubrication chamber 6 includes a rocker 61, a rotating rod 62, a disc 63, an arc block 64, a hydraulic chamber 65, and a drain pipe 66;

[0026] The hydraulic chamber 65 includes a hydraulic plate 651 and a hydraulic rod 652 .

[0027] The bearing of the rocking wheel 61 is installed on the front side of the forced lubrication chamber 6, the rotating rod 62 is fixedly connected to the rocking wheel 61, and the disc 63 is fixed to one end of the rotating rod 62 and is located in the forced lubrication chamber 6;

[0028] The arc block 64 is fixedly mounted on the outer side of the disc 63, the hydraulic chamber 65 is fixedly mounted on the bottom of the inner wall of the forced lubrication chamber 6, the hydraulic plate 651 is slidably connected to the inner wall of the hydraulic chamber 65, the hydraulic rod 652 is fixedly mounted above the hydraulic plate 651 and aligned with the arc block 64, and the outer end of the arc block 64 and the upper end of the hydraulic rod 652 are both arc-shaped;

[0029] The hydraulic plate 651 is connected to the inner wall bottom spring of the hydraulic chamber 65, a through hole is provided on the left side of the bottom of the forced lubrication chamber 6, and a drain pipe 66 is fixedly installed in the through hole, the lower left side of the hydraulic chamber 65 is connected to the upper end pipeline of the drain pipe 66, and a one-way valve 1 is provided in the pipeline, and the bottom of the hydraulic chamber 65 is connected to the external lubricating oil pipeline, and a one-way valve 2 is provided in the pipeline;

[0030] During the operation of the reciprocating piston pump, if its internal lubrication system fails, the operator can manually shake the rocker 61 for forced lubrication. The rocker 61 rotates to drive the disc 63 to rotate through the rotating rod 62, and the disc 63 drives the arc block 64 to rotate through its center until the arc block 64 and the hydraulic rod 652 contact and squeeze each other. The hydraulic rod 652 is forced to push the hydraulic plate 651 to slide downward along the inner wall of the hydraulic chamber 65, and the spring is deformed by the force. At the same time, the lubricating oil at the bottom of the hydraulic plate 651 is squeezed into the drain pipe 66 through the pipeline, and finally discharged from the drain pipe 66 into the reciprocating piston mechanism to lubricate it, which can prevent the reciprocating piston mechanism from not being lubricated and high temperature generated by high friction, thereby avoiding damage to the piston pump and improving the service life and safety of the piston pump. After that, the arc block 64 is out of contact with the hydraulic rod 652, and the spring generates a reaction force to reset the hydraulic plate 651. During the resetting process, lubricating oil is drawn from the outside through the pipeline for replenishment, so that forced lubrication can be continuously and effectively performed.

[0031] The inner wall bearing of the forced lubrication chamber 6 is equipped with a wheel disc 67, and a scroll spring is arranged at the bearing;

[0032] A balance bar 671 is fixedly installed in the middle of the wheel disc 67. The lower end of the balance bar 671 is magnetic. The upper end of the balance bar 671 is in contact with the outer surface of the arc block 64, and the lower end of the balance bar 671 is in contact with the left side of the hydraulic chamber 65.

[0033] The bottom spring of the hydraulic chamber 65 is connected to a magnetic block 653, and the magnetic block 653 is aligned with the lower end of the balance bar 671, and the magnetic poles of the two are opposite;

[0034] A shaking plate 654 is fixed to the right side of the magnetic block 653;

[0035] When the rocking wheel 61 is in the initial position, the outer end of the arc block 64 and the upper end of the balance rod 671 contact and squeeze each other, and the scroll spring is in a deformed state. At this time, the lower end of the balance rod 671 and the magnetic block 653 in the hydraulic chamber 65 generate a magnetic attraction force, so that the magnetic block 653 is located in the upper position, and the spring is deformed by force. Later, when the forced lubrication is performed, the rocking wheel 61 drives the arc block 64 to break contact with the balance rod 671, and the scroll spring generates a reaction force to make the balance rod 671 rotate clockwise through the wheel 67. The lower end of the balance rod 671 is away from the magnetic block 653, the magnetic attraction between the two is reduced, and the spring generates a reaction force. The force pulls the magnetic block 653 downward, thereby driving the shaking plate 654 to move downward, shaking the lubricating oil in the hydraulic chamber 65. The lubricating oil can be shaken during forced lubrication, and the lubricating oil will precipitate in the hydraulic chamber 65 for a long time, thereby preventing the precipitate from being squeezed into the pipeline and causing pipeline blockage, avoiding affecting the discharge of the lubricating oil and improving the use effect. After the rocker 61 is reset, the lower end of the balance bar 671 is reset, and the magnetic attraction generated by the magnetic block 653 pulls the magnetic block 653 upward again to reset. The lubricating oil can be shaken every time forced lubrication is performed, and the precipitate is fully prevented from entering the pipeline.

[0036] A circular arc rod 672 is fixedly installed on the left side of the lower end of the balance rod 671, and a collision rod 661 is fixedly installed on the upper end of the discharge pipe 66;

[0037] The outer end of the arc rod 672 and the upper end of the impact rod 661 are both spherical;

[0038] Through the above steps, the balance rod 671 drives the arc rod 672 to rotate around its center during rotation, thereby contacting the upper end of the impact rod 661 and colliding with each other, so that the drain pipe 66 can be impacted and vibrated every time forced lubrication is performed. On the one hand, it can speed up the discharge of lubricating oil and enable lubrication in the first time. On the other hand, it can prevent oil stains from adhering to the drain pipe 66, thereby avoiding its clogging in the long run.

[0039] The steps of forced lubrication include:

[0040] Step S1, the operator manually turns the crank 61 counterclockwise;

[0041] Step S2, the arc block 64 and the hydraulic rod 652 contact and squeeze each other, the lubricating oil enters the drain pipe 66 through the pipeline, and then is discharged from the drain pipe 66 into the reciprocating plunger mechanism for lubrication, and then the rocker 61 is reversely shaken for secondary lubrication until the rocker 61 is reset;

[0042] Step S3, completing the lubrication work. If lubrication is required more than twice, repeat steps S1 to S2.

[0043] In step S2, the discharge amount of lubricating oil is controlled by manually controlling the swing amplitude of the rocking wheel 61;

[0044] The discharge of lubricating oil is free and controllable, which can ensure the lubrication effect and quality on the one hand, and reduce the loss of lubricating oil and reduce costs on the other hand.

[0045] In step S3, when the amount of lubricating oil discharged is small, the shaking wheel 61 is rotated back and forth alternately in a forward and reverse direction for multiple times, so as to discharge the lubricating oil multiple times;

[0046] Multiple discharges of lubricating oil can provide lubrication to the greatest extent and avoid insufficient discharge of lubricating oil. The discharge amount of lubricating oil can be freely adjusted, which is convenient and efficient.
