Since the first stopper receives the pressure of the grease, the first stopper compresses the spring after being compressed. At this time, the first mounting groove is connected with the rotating groove, and the grease is injected into the gap between the rotating groove and the bearing. Due to the continuous pressurization, the new grease fills the entire rotating groove and adheres to the bearing The bearing is lubricated on the steel ball, and the old grease in the rotating groove receives positive pressure and enters the second installation groove. The second stopper is squeezed by the old grease and compresses the second spring, so that the old grease is discharged from the second installation groove.

In this process, the pulse sensor pumps the amount of grease pumped into the rotating groove corresponding to the recovery time of the speed through the first plunger pump. That is to say, if the speed of the shaft is reduced by a small amplitude, the amount of grease injected into the rotating groove will be very small. On the contrary, if the speed of the shaft is reduced by a large amplitude, it means that the greater the friction force on the bearing, the less grease is left in the rotating groove. At this time, the amount of grease pumped into the rotating groove will be very large. This setting realizes the dynamic adjustment of the grease injection amount, so that the second plunger pump can complete the lubrication of the bearing without stopping during operation, thereby increasing the efficiency of the fracturing process.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the embodiments, which are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the protection scope of the present invention.

[0026] The first plunger 118 pump has the same structure as the second plunger 118 pump. The second plunger 118 pump includes a housing 101, a rotating shaft 102 and a pressurizing assembly. The housing 101 is provided with a liquid inlet 103 and a liquid discharge port 104. One end of the rotating shaft 102 is rotatably connected to the housing 101 through a motor, and the other end of the rotating shaft 102 is rotatably connected to a support portion 105 inside the housing 101. The pressurizing assembly is connected to the rotating shaft 102, and the pressurizing assembly is used to pump the liquid inside the housing 101 out of the liquid discharge port 104. The housing 101 is provided with a lubrication structure. The interior of the first plunger 118 pump is used to hold grease, and the interior of the second plunger 118 pump is used to hold water. The housing 101 is also provided with a pulse sensor 106, and the pulse sensor 106 is used to detect the rotation speed of the rotating shaft 102.

[0027] The lubrication structure includes a rotating groove 107, a first mounting groove 108 and a second mounting groove 109. The first mounting groove 108 and the second mounting groove 109 are located on both sides of the rotating groove 107 and are connected to the rotating groove 107. A bearing 110 is arranged in the rotating groove 107. A first elastic member 111 is arranged in the first mounting groove 108. A first stopper 112 is connected to the first elastic member 111. The first stopper 112 is used to slide closely on the inner wall of the first mounting groove 108. The discharge port 104 on the first plunger 118 pump is connected to the first mounting groove 108. A second elastic member 113 is arranged in the second mounting groove 109. A second stopper 114 is connected to the second elastic member 113. The second stopper 114 is used to slide closely on the inner wall of the second mounting groove 109.

[0028] The utility model mainly comprises a first plunger 118 pump and a second plunger 118 pump, wherein the first plunger 118 pump is used for grease lubrication of the second plunger 118 pump; in actual use, when fracturing is performed underground, the first plunger 118 pump is first sealed and connected to the first mounting groove 108 through an oil injection pipe, and then the discharge port 104 of the second plunger 118 pump is aligned with the wellhead, and the discharge port 104 is extended into the ground through a water pipe. When in use, the motor connected to the internal rotating shaft 102 of the second plunger 118 pump is driven to start, and after the motor is started, the rotating shaft 102 is driven to rotate, and the rotating shaft 102 drives the pressurizing component to pump the water coming in from the liquid inlet 103 out of the discharge port 104, and finally the water is pumped out through the water pipe. The pump is pumped into the ground to pressurize the ground; when the pulse sensor 106 detects that the speed of the rotating shaft 102 slows down, the pulse sensor 106 transmits a signal to the controller, and the controller controls the motor connected to the first plunger 118 pump to rotate, and the grease enters the housing 101 through the liquid inlet 103 on the first plunger 118 pump, and is finally discharged from the discharge port 104 to the first mounting groove 108. Since the first stopper 112 receives the pressure of the grease, the first stopper 112 compresses the spring after being compressed. At this time, the first mounting groove 108 is connected with the rotating groove 107, and the grease is injected into the gap between the rotating groove 107 and the bearing 110. Due to the continuous pressurization, the new grease fills the entire The rotating groove 107 is attached to the steel ball of the bearing 110 to lubricate the bearing 110, and the old grease in the rotating groove 107 receives positive pressure and enters the second mounting groove 109. The second stopper 114 is squeezed by the old grease and compresses the second spring, so that the old grease is discharged from the second mounting groove 109. At this time, the good lubrication state between the rotating shaft 102 and the bearing 110 is restored, and the speed of the rotating shaft 102 is restored. The pulse sensor 106 controls the motor connected to the first plunger 118 pump to stop through the controller, thereby realizing automatic lubrication of the bearing 110. In this process, the pulse sensor 106 correspondingly passes through the first plunger 118 according to the recovery time of the speed. The piston 118 pumps the amount of grease pumped into the rotating groove 107 at a corresponding time. That is to say, if the speed of the rotating shaft 102 decreases by a small amount, the amount of grease injected into the rotating groove 107 will be very small. On the contrary, if the speed of the rotating shaft 102 decreases by a large amount, the greater the friction force on the bearing 110, the less grease is left in the rotating groove 107. At this time, the amount of grease pumped into the rotating groove 107 will be very large. This setting realizes dynamic adjustment of the grease injection amount, so that the second piston 118 pump can complete the lubrication of the bearing 110 without stopping during operation, thereby increasing the efficiency of the fracturing process.

[0029] In some embodiments, the first stopper 112 and the second stopper 114 are respectively slidably matched with the first mounting groove 108 and the second mounting groove 109 through a sliding assembly.

[0030] In actual use, the use of the sliding assembly can make the sliding between the first stopper 112 and the second stopper 114 and the first installation groove 108 and the second installation groove 109 smoother.

[0031] In some embodiments, the sliding assembly includes two T-shaped slide rails and two T-shaped slide grooves, the two T-shaped slide rails are respectively arranged on the first stop block 112 and the second stop block 114, and the two T-shaped slide grooves are respectively arranged on the first mounting groove 108 and the second mounting groove 109; the T-shaped slide rail on the first stop block 112 slides in cooperation with the T-shaped slide groove in the first mounting groove 108, and the T-shaped slide rail on the second stop block 114 slides in cooperation with the T-shaped slide groove in the second mounting groove 109.

[0032] In actual use, the purpose of setting the T-shaped slide rail and the T-shaped slide groove is to fix the first stop block 112 and the second stop block 114 at one end of the side wall of the first mounting groove 108 and the second mounting groove 109 to prevent the first stop block 112 and the second stop block 114 from being stuck inside the first mounting groove 108 and the second mounting groove 109. Setting the slide rail and the slide groove into a T shape can prevent the first stop block 112 and the second stop block 114 from shaking inside the first mounting groove 108 and the second mounting groove 109 respectively.

[0033] In some embodiments, the pressurizing assembly includes a swash plate 117, a plunger 118, a plug hole 119 and a plurality of one-way valves 120. The swash plate 117 is arranged on the rotating shaft 102. The swash plate 117 is provided with an annular groove 121. A rotating ring 122 is arranged inside the annular groove 121. A plurality of movable sleeves 123 are symmetrically arranged on the rotating ring 122. The movable sleeves 123 are fixedly connected to the rotating ring 122. There are a plurality of plug holes 119, and the number of the plug holes 119 corresponds to the number and position of the movable sleeves 123. The plurality of plug holes 119 are all arranged on the support portion 105. The plunger 118 is slidably arranged at one end of the plug hole 119, and the one-way valve 120 is arranged at the other end of the plug hole 119. A flow channel 124 is arranged in the plunger 118, and the one-way valve 120 is arranged in the flow channel 124. The end of the plunger 118 is a spherical structure, and the end of the plunger 118 is movably connected to the movable sleeve 123.

[0034] In actual use, when the motor is started, water is pumped into the liquid inlet 103 at the same time. Since the output shaft of the motor is connected to the rotating shaft 102, the output shaft of the motor rotates and drives the rotating shaft 102 to rotate inside the housing 101. After the rotating shaft 102 rotates, it drives the swash plate 117 to rotate inside the housing 101. After the swash plate 117 rotates, the rotating ring 122 cooperates with the rotating ring 122, so the rotating ring 122 will rotate relative to the swash plate 117. After the swash plate 117 rotates, the rotating ring 122 does not move. After the swash plate 117 rotates, It will drive several plungers 118 to slide back and forth in the plug hole 119. When the plunger 118 rises, water enters the plunger 118 from the flow channel 124, and the water pressure impacts the one-way valve 120, which flows out from the bottom of the plunger 118 and enters the plug hole 119. At this time, the one-way valve 120 inside the plug hole 119 is closed because it is not impacted by the water pressure. When the plunger 118 falls, the water inside the plug hole 119 is squeezed, and the water pressure opens the one-way valve 120 in the plug hole 119, thereby achieving the purpose of pressurizing and discharging water from the drain port 104 when the plunger 118 falls.

[0035] It should be noted that, since the plunger 118 will not be disengaged from the plug hole 119, the plunger 118 and the plug hole 119 form a horizontal limit straight line, so the swash plate 117 cannot drive the rotating ring 122 to rotate through friction after rotating.

[0036] In some embodiments, the flow channel 124 is a Y-shaped flow channel 124 .

[0037] In actual use, the Y-shaped flow channel 124 can allow liquid to enter the interior of the plunger 118 from two directions, thereby improving the liquid intake efficiency of the plunger 118 .

[0038] In some embodiments, a rotation hole 125 is disposed on the support portion 105 , a rotation member 126 is disposed inside the rotation hole 125 , and the rotation shaft 102 is rotationally matched with the rotation hole 125 through the rotation member 126 .

[0039] In actual use, the rotating member 126 may be a sleeve or a bearing 110 . As an optional implementation, in this embodiment, the rotating member 126 is a bearing 110 .

[0040] In some embodiments, an oiling nozzle 127 is disposed on the first mounting groove 108 , and the first plunger 118 pump is connected to the first mounting groove 108 through the plunger 118 nozzle.

[0041] In actual use, the purpose of providing the oil filling nozzle 127 is to facilitate the connection between the oil filling pipe and the first mounting groove 108 .

[0042] In some embodiments, a plurality of sealing rings 128 are disposed at the connection between the housing 101 and the rotating shaft 102 , inside the rotating hole 125 , and below the plug hole 119 ; the purpose of providing the sealing rings 128 is to prevent liquid leakage inside the housing 101 .

[0043] In some embodiments, a drainage channel 129 is formed between the support portion 105 and the housing 101 , and the drainage channel 129 is connected to the plug hole 119 ;

[0044] In actual use, the liquid flowing out of the plug hole 119 passes through the drainage channel 129 and is finally discharged from the drainage port 104 .

[0045] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "two ends", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
