DETAILED DESCRIPTION

[0049] The following will be combined with the specific implementation of the present invention to clearly and completely describe the technical solution in the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementation. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figure 1-13 As shown, a reciprocating pump lubrication system of the present invention includes a base 1, a reducer 2, a crankcase 3, a piston pump box 4 and an oil pipeline 5.

[0051] The reducer 2, crankcase 3, and piston pump case 4 are all fixedly arranged on the base 1 and connected in sequence. Specifically, the input end of the reducer 2 is a motor, which is connected to the output end of the reducer 2 through a plurality of gears meshing with each other inside the reducer 2. The output end of the reducer 2 is fixedly connected to the input end of the crankshaft in the crankcase 3 through a coupling. The crankshaft in the crankcase 3 drives the connecting rod in the crankcase 3 to reciprocate. The piston in the piston pump case 4 is fixedly connected to the connecting rod in the crankcase 3, so that when the motor is started, the piston is driven to reciprocate to realize the delivery of the medium.

[0052] When the reciprocating pump is running, the gears in the reducer 2, the crankshaft and connecting rod in the crankcase 3, the piston and cylinder in the piston pump box 4, and the bearings used in the rotating mechanism will continue to wear during operation. In order to extend their service life and improve their operating efficiency, the above-mentioned components need to be forced to be lubricated.

[0053] Forced lubrication requires an oil tank 13 and an oil pipeline 5. In the prior art, both are usually fixedly mounted on the top side of the base 1, which not only increases the overall space occupied by the reciprocating pump, but also makes the oil tank 13 vulnerable to damage. Therefore, the present invention configures the base 1 to include a fixing frame 11, two connecting pipes 12 and an oil tank 13, such as Figure 1 and Figure 2 As shown, the connecting pipe 12 and the oil tank 13 are both fixedly arranged on the fixing frame 11, the oil tank 13 and the fixing frame 11 are integrated together, and the reducer 2, the crankcase 3 and the piston pump box 4 are all fixedly arranged on the oil tank 13, the reducer 2, the crankcase 3 and the piston pump box 4 are all sealed and connected with the two connecting pipes 12 through the oil pipeline 5, and by integrating the oil tank 13 on the fixing frame 11 and allowing the oil tank 13 to also play the role of supporting other components, the occupied space of the reciprocating pump can be effectively reduced, and the oil tank 13 can be fully protected.

[0054] like Figure 3 As shown, the base 1 also includes a straight pipe 14 and a control valve 15. The straight pipe 14 is arranged on the oil tank 13, and its two ends extend to the outside of the oil tank 13, and are sealed and connected with one end of the two connecting pipes 12 away from the oil pipeline 5 respectively. The middle position of the straight pipe 14 is located in the oil tank 13, and two diversion holes 101 are provided on the peripheral side of the straight pipe 14 located in the oil tank 13. The oil pipeline 5 and the straight pipe 14 can drive the lubricating oil to circulate between the oil tank 13, the reducer 2, the crankcase 3 and the piston pump box 4.

[0055] The oil tank 13 is not only used to store lubricating oil, but also can buffer and stabilize the lubricating oil pressure and accommodate the expanded oil of the lubricating system. For the piston pump box 4 whose piston stroke can be adjusted or the number of pistons can be changed and the reciprocating pumps in other working conditions, the volume requirements of the oil tank 13 are also different. A plurality of oil tanks 13 are arranged in the reciprocating pump, and a straight pipe 14 is arranged in the oil tank 13. The on-off control of the diverter hole 101 and the on-off control of the straight pipe 14 can be utilized to allow the flowing lubricating oil to flow only in part of the oil tank 13. This technical effect can be achieved by fixing the control valve 15 in the straight pipe 14 and the two diverter holes 101, and using a plurality of control valves 15 to respectively control the on-off of the straight pipe 14 and the on-off of the diverter hole 101.

[0056] In order to improve the operation convenience of the control valve 15 and reduce the number of control valves 15, the diversion hole 101 is located at the bottom side of the straight pipe 14, and the control valve 15 is configured to include a valve cylinder 151, a limit ring 152 and a gravity ball 153, such as Figure 3 and Figure 5 As shown, the valve cylinder 151 passes through the diverter hole 101 and is sealed and fixed thereto. The lower end of the valve cylinder 151 is spaced apart from the bottom side of the straight pipe 14. The first through hole 102 and the second through hole 103 are opened on the circumferential side of the valve cylinder 151. The first through hole 102 and the second through hole 103 are respectively located on both sides of the center line of the valve cylinder 151, and the first through hole 102 is located at the bottom of the straight pipe 14, and the second through hole 103 is located at the top of the straight pipe 14. The limit ring 152 is fixedly set at the bottom end of the valve cylinder 151, and the gravity ball 153 is sealed and slid in the valve cylinder 151 and abuts against the top side of the limit ring 152. The outer diameter of the gravity ball 153, the inner diameter of the valve cylinder 151 and the inner diameter of the straight pipe 14 are the same. The two control valves 15 in the same oil tank 13 are arranged opposite to each other; as shown in FIG. Figure 5 As shown in FIG. 1 , when the lubricating oil flows from right to left, the lubricating oil flows from the right end of the straight pipe 14 to the left end of the straight pipe 14 through the first through hole 102 and the second through hole 103 in sequence. When the oil tank 13 is turned over, the gravity ball 153 slides into the straight pipe 14, as shown in FIG. Figure 6 As shown, at this time, the gravity ball 153 blocks the interior of the straight pipe 14, and when the lubricating oil flows from the right end of the straight pipe 14 to the left, it flows to the interior of the oil tank 13 through the first through hole 102 and the interior of the limit ring 152 in turn, and then flows to the left end of the straight pipe 14 through another control valve 15 in the same oil tank 13, thereby realizing the on-off control of the straight pipe 14 and the diversion hole 101, and controlling the number of oil tanks 13 participating in the circulation of the lubricating oil; the flipping process of the oil tank 13 is not a direct rotation of 180 degrees, but a process of disassembly and flipping installation, which is abbreviated as flipping.

[0057] like Figure 6 As shown, when the oil tank 13 participates in the circulation of the lubricating oil, the limiting ring 152 is located above the oil tank 13, and the lubricating oil flowing out of the limiting ring 152 is blown upward, and will not directly blow the bottom side of the oil tank 13, thereby not blowing up impurities at the bottom of the oil tank 13, and preventing impurities at the bottom of the oil tank 13 from entering the circulation of the lubricating oil, thereby achieving a certain filtering effect.

[0058] The oil tank 13 of the existing reciprocating pump can only store lubricating oil for circulating flow. When the lubricating oil reaches the end of its service life, it is necessary to first take out the lubricating oil in the original oil tank 13 and then inject new lubricating oil into the oil tank 13. The oil tank 13 provided with the control valve 15 in the present invention can realize quick replacement of the lubricating oil. Specifically, the lubricating oil is stored inside both the oil tank 13 participating in the lubricating oil circulation and the oil tank 13 not participating in the lubricating oil circulation. When the circulating lubricating oil needs to be replaced, the oil tanks 13 are turned over one by one, so that the oil tank 13 that originally did not participate in the lubricating oil circulation participates in the lubricating oil circulation, and the oil tank 13 that originally participated in the lubricating oil circulation does not participate in the lubricating oil circulation, thereby realizing the lubricating oil replacement operation; of course, this replacement operation is not thorough, but it can greatly improve the maintenance efficiency of the lubricating oil.

[0059] It is preferred that the straight pipe 14 is located in the middle of the oil tank 13 and the oil tank 13 is symmetrical about the center line of the straight pipe 14, that is, when the oil tank 13 is turned over, the oil tank 13 is in the same position before and after the turning over to avoid interference with other components after the turning over.

[0060] like Figure 5 As shown, at this time, the upper end of the valve cylinder 151 is preferably sealed and connected to the inner wall of the straight pipe 14. When the oil tank 13 is turned over, as shown in FIG. Figure 6 As shown, the flow of lubricating oil will not only not blow the bottom of the gravity ball 153, but also exert a downward force on the gravity ball 153 to prevent the gravity ball 153 from changing its position; similarly, Figure 5 As shown, the gravity ball 153 is sealed against the top side of the limiting ring 152, that is, the gravity ball 153 and the valve cylinder 151 and the limiting ring 152 form two sealing structures, which effectively ensures the sealing performance of the device.

[0061] like Figure 2 and Figure 7 As shown, the oil tanks 13 and the straight pipes 14 are provided with multiple groups, each group is provided with multiple, and the multiple oil tanks 13 and the multiple straight pipes 14 correspond one to one, the multiple straight pipes 14 of the same group are arranged in series between the two connecting pipes 12, and the multiple straight pipes 14 of different groups are arranged in parallel, and the multiple groups of straight pipes 14 form a plurality of parallel lubricating oil passages. Therefore, one or more lubricating oil passages can be cancelled by disassembling one or more groups of straight pipes 14, thereby controlling the number of oil tanks 13 participating in the circulation of the lubricating oil.

[0062] The connecting pipe 12 includes an oil inlet pipe 121 and an oil drain pipe 122. The lubricating oil flows into the oil tank 13 through the oil inlet pipe 121 and is then transported to various oil-consuming mechanisms through the oil drain pipe 122. A self-closing valve 16 is also provided in the base 1. The self-closing valve 16 is used to self-close the straight-through pipe 14 to avoid oil leakage in the straight-through pipe 14 close to the oil inlet pipe 121 when an oil tank 13 is removed.

[0063] As a preferred embodiment, the self-shutoff valve 16 includes a valve core 161, a valve stem 162, a first spring 163 and an adjusting frame 164. The valve core 161 is fixedly arranged in the straight pipe 14 at one end away from the oil inlet pipe 121, and a connecting hole 104 is opened inside the valve core 161. The valve stem 162 is slidably arranged in the valve core 161. The first spring 163 is fixedly arranged on the valve core 161 and abuts against the side of the valve stem 162 close to the oil inlet pipe 121. Figure 8 As shown, in the natural state, the valve stem 162 can be blocked by the elastic force of the first spring 163 on the valve stem 162 or the pressure of the lubricating oil in the straight pipe 14, thereby blocking the straight pipe 14 and avoiding oil leakage; Fig. 9 As shown, the adjustment frame 164 is a hollow structure, and the adjustment frame 164 is detachably fixed to one end of the straight-through pipe 14 near the oil inlet pipe 121, as shown in FIG. Fig.10 As shown, when two adjacent straight-through tubes 14 are assembled, the adjustment frame 164 in the straight-through tube 14 abuts against the end of the valve stem 162 in the adjacent straight-through tube 14 away from the oil inlet pipe 121, so that the valve stem 162 does not block the connecting hole 104, allowing the lubricating oil to flow from one straight-through tube 14 to the other straight-through tube 14. When the two straight-through tubes 14 are separated, the first spring 163 will also abut the valve stem 162 to block the connecting hole 104, so as to avoid oil leakage when the oil tank 13 is disassembled.

[0064] like Figure 8-Figure 10 As shown, in order to improve the connection convenience of two adjacent straight tubes 14, a slot is preferably opened at one end of the straight tube 14, and a second spring and a slide cylinder are arranged at the other end of the straight tube 14. When the ends of the two straight tubes 14 are aligned, the second spring is used to push the slide cylinder to slide to the connection position of the two straight tubes 14, thereby sealing the connection position of the two straight tubes 14.

[0065] like Figure 7 As shown, in order to realize the parallel connection of multiple groups of straight-through pipes 14, the oil inlet pipe 121 is preferably configured to include a main pipe 1211 and multiple branch pipes 1212. The main pipe 1211 is fixedly arranged on the fixing frame 11, one end of the branch pipe 1212 is fixedly arranged on the main pipe 1211 and is sealed and connected with the interior thereof, and the other end is sealed and connected with the straight-through pipe 14. The multiple branch pipes 1212 correspond one-to-one to the multiple groups of straight-through pipes 14. In order to avoid leakage of lubricating oil in the branch pipes 1212 when the oil tank 13 is disassembled, a valve core 161, a valve stem 162 and a first spring 163 are arranged in each branch pipe 1212, and an adjusting frame 164 is arranged in the corresponding straight-through pipe 14; similarly, the structure of the oil drain pipe 122 may also be the same as that of the oil inlet pipe 121.

[0066] like Figure 2 and Fig.12 As shown, in order to facilitate the integration of the fixed oil tank 13, it is preferred to open a mounting groove 105 on the top side of the fixing frame 11, and install the oil tank 13 in the mounting groove 105; the bottom of the fixing frame 11 is preferably set to be hollow, which can not only reduce the overall weight of the base 1, but also can promptly detect oil leakage problems of the oil tank 13 and the straight pipe 14, so as to carry out timely maintenance.

[0067] like Fig.11 and Fig.12 As shown, the oil tank 13 includes a box body 131, an upper frame plate 132, a lower frame plate 133 and a top cover 134. The box body 131 is located in the mounting groove 105. The upper frame plate 132 is detachably fixed to the top side of the box body 131 and is flush with the top side of the box body 131 and the top side of the fixing frame 11; the lower frame plate 133 is detachably fixed to the bottom side of the box body 131 and is flush with the bottom side of the box body 131. The bottom side of the lower frame plate 133 is flush with the mounting groove 105. 5, and the outer diameters of the upper frame plate 132 and the lower frame plate 133 are both larger than the outer diameter of the box body 131, so that the cross-section of the oil tank 13 is in an I-shape, which not only reserves an operating space for the connection operation of the straight-through pipe 14, but also protects the connection position of the straight-through pipe 14; and by disassembling the upper frame plate 132 and the lower frame plate 133, the occupied space of the oil tank 13 can be reduced, thereby facilitating the overturning of the oil tank 13.

[0068] The two adjacent upper frame plates 132 are sealed and connected via rubber gaskets, the two adjacent lower frame plates 133 are sealed and connected via rubber gaskets, and the fixing frame 11 is sealed and connected to the upper frame plate 132 and the lower frame plate 133 respectively via rubber gaskets, thereby improving the connection strength, sealing performance, and shock-absorbing and buffering performance between the two adjacent oil tanks 13 and between the oil tank 13 and the fixing frame 11.

[0069] An opening 106 is provided on the top side of the box body 131, and lubricating oil is injected into or discharged from the box body 131 through the opening 106. The top cover 134 is detachably fixed to the box body 131 and blocks the opening 106, thereby preventing the lubricating oil in the oil tank 13 from overflowing from the opening 106 during the operation of the device.

[0070] When the reducer 2, crankcase 3 and piston pump box 4 are directly installed on the top side of the oil tank 13, certain damage will be caused to the oil tank 13. When the reducer 2, crankcase 3 and piston pump box 4 are connected and fixed to the oil tank 13, it is inconvenient to turn over the oil tank 13. For this reason, a top plate 17 is arranged in the base 1. The top plate 17 is abutted against the top sides of multiple oil tanks 13 and is fixedly connected to the reducer 2, crankcase 3 and piston pump box 4. The top plate 17 is directly fixedly connected to the reducer 2, crankcase 3 and piston pump box 4. Even if the oil tank 13 is turned over for use, its connection position will not be affected. At the same time, the top plate 17 can also buffer the pressure on the oil tank 13 caused by other components to protect the oil tank 13.

[0071] As a preferred embodiment, the top plate 17 includes a plate body 171, a fixing seat 172, a plurality of columnar protrusions 173 and a plurality of spherical protrusions 174. The plate body 171 is set against the top side of the box body 131, and the fixing seat 172 is fixedly set on the top side of the plate body 171 and is fixedly connected to the reducer 2, the crankcase 3 and the piston pump box 4. The fixing seat 172 is usually a structurally firm frame structure to enhance the fixing firmness of the reducer 2, the crankcase 3 and the piston pump box 4.

[0072] The columnar protrusions 173 are fixedly arranged on the top side of the plate body 171 , and the plurality of columnar protrusions 173 correspond one-to-one to the plurality of top covers 134 , and the columnar protrusions 173 are located above the corresponding top covers 134 , thereby strengthening the protection of the top covers 134 and preventing the top covers 134 from being damaged when the top plate 17 is subjected to pressure.

[0073] The spherical protrusion 174 is fixedly set on the top side of the plate body 171. The spherical protrusion 174 has the advantages of being thick in the middle and thin at both ends, which not only makes it convenient to insert the lifting ring, but also makes it convenient to fix the lifting ring. Multiple spherical protrusions 174 correspond to multiple columnar protrusions 173 one by one. The spherical protrusions 174 are preferably arranged at intervals on the sides of the columnar protrusions 173. After the lifting ring is put on the outside of the spherical protrusion 174, the columnar protrusion 173 can be used to limit the lifting ring to a certain extent, thereby preventing the lifting ring from detaching from the spherical protrusion 174.

[0074] like Figure 1 and Fig.13 As shown, the oil pipeline 5 includes multiple branch pipes and oil pumps. The branch pipes are fixedly arranged between the straight pipe 14, the reducer 2, the crankcase 3 and the piston pump box 4. The oil pump is used to drive the lubricating oil in the branch pipe to circulate.

[0075] A method of using a reciprocating pump lubrication system of the present invention is as follows:

[0076] S1, determine the total amount L of lubricating oil required when the reducer 2, crankcase 3 and piston pump box 4 are in operation according to the internal space of the reducer 2, crankcase 3 and piston pump box 4, the stroke of the piston in the piston pump box 4 and the number of pistons used.

[0077] S2, determining the number m of the oil tanks 13 and the number n of the straight pipes 14 involved in the circulation of the lubricating oil according to L, wherein m and n are both natural numbers, and the sum of m and n is equal to the number of the oil tanks 13.

[0078] S3, assemble the oil tanks 13 so that the number of oil tanks 13 whose internal limit rings 152 are located below the internal straight pipes 14 is n, and the number of oil tanks 13 whose internal limit rings 152 are located above the internal straight pipes 14 is m.

[0079] S4, assemble other components to use the reciprocating pump.

[0080] Among them, when pouring lubricating oil into the oil tank 13, it is preferred that all the oil tanks 13 store lubricating oil. When the lubricating oil in the oil tank 13 participating in the lubricating oil circulation needs to be replaced, the lubricating oil can be quickly replaced by flipping the oil tank 13 participating in the lubricating oil circulation and the oil tank 13 not participating in the lubricating oil circulation, thereby reducing the downtime of the reciprocating pump. Since the oil tank 13 storing the replaced lubricating oil no longer participates in the circulation of the lubricating oil, the lubricating oil inside it can be replaced without affecting the operation of the reciprocating pump.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
