Description

Technical Field

[0001] This utility model relates to the field of gear pumps, and more particularly to a split-type electric gear lubrication pump. Background Technology

[0002] A gear pump is a rotary pump used to transport liquids, generally consisting of a motor, mounting base, gear pump, and oil tank. An oil passage is located within the mounting base. When the two gears of the gear pump mesh, the volume of the space on the disengaged side of the gears increases, drawing oil into the mounting base through pressure difference. Simultaneously, the volume of the space on the meshing side of the gears decreases, pumping the oil out of the mounting base through pressure difference, thus completing the oil transport process.

[0003] In existing technology, to facilitate installation and optimize structural layout, the mounting base is divided into two parts: a first mounting base and a second mounting base. The motor is mounted on the first mounting base, and the oil tank is mounted on the second mounting base. The first and second mounting bases are installed face-to-face and then locked with screws. Sealing rings or similar devices can be used to reinforce the seal between them. However, this installation method is susceptible to problems such as vibration, unevenness, or misalignment, which can cause the two end faces to shift, leading to seal failure and oil leakage.

[0004] Therefore, there is an urgent need for a split-type electric gear lubrication pump that can improve installation sealing and flexibility to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a split-type electric gear lubrication pump that helps improve installation sealing and flexibility.

[0006] To achieve the above objectives, this utility model provides a split-type electric gear lubrication pump, comprising a motor, a pump base, a gear pump, a fixed base, and an oil tank. The motor and the gear pump are respectively mounted on the pump base. The motor is connected to the gear pump and drives the gear pump to operate. The oil tank is mounted on the top of the fixed base, which has an oil storage chamber. The outlet of the oil tank communicates with the oil storage chamber. At least a portion of the gear pump is inserted into the oil storage chamber. The pump base is fixedly mounted on the fixed base and has a first oil outlet channel. The motor drives the gear pump to operate, causing the gear pump to pump oil from the oil storage chamber and pump it out to the first... The pump base also has a docking protrusion extending toward the fixed seat. The docking protrusion is arranged to at least partially surround the toothed pump. At least a portion of the docking protrusion penetrates into the oil storage chamber and seals the oil storage chamber. The portion of the docking protrusion that penetrates into the oil storage chamber is sealed to the inner wall of the oil storage chamber by a first sealing member. The fixed seat has a second oil outlet channel. The first oil outlet channel and the second oil outlet channel are connected by a first mating connector. The two ends of the first mating connector are respectively inserted into the first oil outlet channel and the second oil outlet channel and sealed to each other.

[0007] Preferably, the mating protrusion has a cylindrical structure and a mating cavity, in which at least a portion of the toothed pump is installed.

[0008] Preferably, the outer wall of the mating protrusion is provided with an installation groove, and the first seal is installed in the installation groove.

[0009] Preferably, the motor, pump base, and fixed base are arranged in sequence from left to right, and one end face of the pump base and one end face of the fixed base are fitted together.

[0010] Preferably, the pump base is also provided with a docking channel, in which a control valve assembly is installed. When the gear pump is running, it pumps oil to the docking channel for oiling. When the gear pump is oiling, the control valve assembly is in a first open state, which connects the docking channel with the first oil outlet channel and cuts off the connection between the first oil outlet channel and the oil storage chamber. When the gear pump stops oiling the docking channel, the control valve assembly is in a second open state, which connects the first oil outlet channel with the oil storage chamber and cuts off the connection between the first oil outlet channel and the docking channel.

[0011] Preferably, the control valve assembly includes a mounting body, a docking valve, and a control spring. The mounting body has a connecting channel that communicates with an oil reservoir. The docking valve is located on one side of the mounting body. The control spring is fitted onto the mounting body and presses against the docking valve so that the docking valve always tends to move away from the mounting body. When the control valve assembly is in the first open state, the docking valve compresses the control spring and rests against the mounting body, thereby cutting off the communication between the first oil outlet channel and the oil reservoir. When the control valve assembly is in the second open state, the docking valve is pushed away from the mounting body by the control spring, so that the first oil outlet channel communicates with the connecting channel.

[0012] Preferably, one end of the docking valve forms a plug end, and a check skirt is formed around the plug end of the docking valve. When the control valve assembly is in the first open state, the docking valve compresses the control spring and the plug end rests against the mounting body. The check skirt is contracted under the pressure of the oil in the docking channel. When the control valve assembly is in the second open state, the plug end is pushed away from the mounting body by the control spring, and the check skirt opens to cut off the connection between the docking channel and the first oil outlet channel.

[0013] Preferably, the pump base is also provided with a pressure regulating channel, which is connected to the docking channel, and a pressure regulating valve is installed in the pressure regulating channel.

[0014] Preferably, the pump base is further provided with a first pressure relief channel, which is connected to the connecting channel. The fixed base is provided with a second pressure relief channel, which is connected to the oil storage chamber. The first pressure relief channel and the second pressure relief channel are connected by a second mating connector, with both ends of the second mating connector inserted into the first pressure relief channel and the second pressure relief channel, respectively.

[0015] Preferably, a second seal is fitted on the first pair of mating parts, and the first pair of mating parts are sealed together in the first oil outlet channel and the second oil outlet channel by means of the second seal. A third seal is fitted on the second pair of mating parts, and the second pair of mating parts are sealed together in the first pressure relief channel and the second pressure relief channel by means of the third seal.

[0016] Compared with existing technologies, this utility model features a split-type electric gear lubrication pump comprising a pump base and a fixed base. The pump base provides support for the motor, and the fixed base provides support for the oil tank. This design eliminates the need for the original integrated base (which supports both the motor and oil tank), instead employing a split structure for easier installation and structural optimization. Furthermore, this utility model incorporates a connecting protrusion that penetrates into and seals the oil storage chamber. The portion of the protrusion penetrating the oil storage chamber is sealed to the inner wall of the chamber using a first sealing element, thus completing the sealed connection between the pump base and the fixed base within the oil storage chamber. The pumped oil flows sequentially through a first oil outlet channel and a second oil outlet channel. In this utility model, a first mating connector is used to seal the connection between the first and second oil outlet channels. Therefore, this utility model adopts a plug-in installation method, abandoning the original end-face assembly sealing method. As a result, it has high adjustability and flexibility, and can resist a certain degree of vibration, unevenness or misalignment. Even if the end faces of the pump base and the fixed base are offset or misaligned, it will not cause the seal between them to fail. Attached Figure Description

[0030] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] like Figures 1 to 9 , Figure 11 and Figure 12As shown, this utility model discloses a split-type electric gear lubrication pump 100, including a motor 10, a pump base 20, a gear pump 30, a fixed base 40, and an oil tank 50. The motor 10 and the gear pump 30 are respectively mounted on the pump base 20. The motor 10 is connected to the gear pump 30 and drives the gear pump 30 to operate. The oil tank 50 is mounted on the top of the fixed base 40. The fixed base 40 has an oil storage chamber 41, and the outlet of the oil tank 50 communicates with the oil storage chamber 41. At least a portion of the gear pump 30 is inserted into the oil storage chamber 41. The pump base 20 is fixedly mounted on the fixed base 40. The pump base 20 has a first oil outlet channel 21. The motor 10 drives the gear pump 30 to operate, causing the gear pump 30 to pump oil from the oil storage chamber 41 and pump it out to the first oil outlet channel 21. The pump base 20 also has a mating protrusion 22 extending towards the fixed base 40, and the mating protrusion 22 is arranged to at least partially surround the gear pump 30. At least a portion of the mating protrusion 22 penetrates into the oil storage chamber 41 and seals the oil storage chamber 41. The portion of the mating protrusion 22 that penetrates into the oil storage chamber 41 is sealed to the inner wall of the oil storage chamber 41 by a first sealing member 60 to prevent oil leakage. The fixed base 40 is provided with a second oil outlet channel 42. The first oil outlet channel 21 and the second oil outlet channel 42 are connected by a first mating connector 70. The two ends of the first mating connector 70 are respectively inserted into the first oil outlet channel 21 and the second oil outlet channel 42 and sealed together.

[0032] In this invention, the split-type electric gear lubrication pump 100 includes a pump base 20 and a fixed base 40. The pump base 20 provides support for the motor 10, and the fixed base 40 provides support for the oil tank 50. This design abandons the original integrated base (which supports both the motor and the oil tank) and adopts a split structure, facilitating installation and optimizing the structure. Furthermore, this invention features a connecting protrusion 22 that penetrates into the oil storage chamber 41 and seals it. The portion of the connecting protrusion 22 penetrating the oil storage chamber 41 is sealed to the inner wall of the oil storage chamber 41 by a first sealing member 60, thus completing the sealed connection between the pump base 20 and the fixed base 40 in the oil storage chamber 41. The pumped oil flows successively through the first oil outlet channel 21 and the second oil outlet channel 42. In this invention, a first mating connector 70 is used to seal the connection between the first oil outlet channel 21 and the second oil outlet channel 42. Therefore, this utility model adopts a plug-in installation method, abandoning the original end-face assembly sealing method. As a result, it has high adjustability and flexibility, and can resist a certain degree of vibration, unevenness or misalignment. Even if the end faces of the pump seat 20 and the fixed seat 40 are offset or misaligned, it will not cause the seal between them to fail.

[0033] Preferably, the pump base 20 and the fixed base 40 are roughly square, but not a regular square structure. The toothed pump 30 of this utility model can adopt an existing structure, and its structure will not be described in detail here.

[0034] like Figure 3 , Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, the mating protrusion 22 has a cylindrical structure, but it can also be configured with other shapes depending on the actual application requirements. The mating protrusion 22 has a mating cavity 221, in which at least a portion of the gear pump 30 is installed. The mating cavity 221 facilitates the installation of the gear pump 30. Furthermore, the outer wall of the mating protrusion 22 has a mounting groove 222, in which the first sealing element 60 is installed. The mounting groove 222 helps to enhance the installation stability of the first sealing element 60 and prevents the first sealing element 60 from shifting.

[0035] like Figures 1 to 5 , Figures 9 to 13 As shown, the motor 10, pump base 20, and fixed base 40 are arranged from left to right for easy assembly and optimized structural layout. One end face of the pump base 20 and one end face of the fixed base 40 are mated together. For example, they can be mated together by using a protruding edge and a slot.

[0036] like Figure 5 , Figure 6 and Figure 7 As shown, the pump base 20 is also provided with a docking channel 23, in which a control valve assembly 24 is installed. When the gear pump 30 is running, it pumps the oil to the docking channel 23 for oiling.

[0037] When the gear pump 30 is pumping oil, the control valve assembly 24 is in a first open state, which connects the docking channel 23 to the first oil outlet channel 21 and disconnects the first oil outlet channel 21 from the oil storage chamber 41 (e.g., Figure 6 ).

[0038] At this time, the oil pumped into the docking channel 23 flows into the first oil outlet channel 21, and then into the second oil outlet channel 42, and finally flows out.

[0039] When the gear pump 30 stops supplying oil to the docking channel 23, the control valve assembly 24 is in a second open state, which connects the first oil outlet channel 21 to the oil storage chamber 41 and cuts off the connection between the first oil outlet channel 21 and the docking channel 23. Figure 7 At this point, the oil in the second oil outlet channel 42 and the first oil outlet channel 21 flows into the oil storage chamber 41 and back into the oil tank 50, thus relieving pressure. Oil cannot flow into the docking channel 23, thus preventing backflow.

[0040] like Figure 6 and Figure 7As shown, the control valve assembly 24 includes a mounting body 241, a docking valve 242, and a control spring 243. The mounting body 241 has a connecting channel 2411 that communicates with the oil reservoir 41. The docking valve 242 is located on one side of the mounting body 241. The control spring 243 is fitted onto the mounting body 241 and presses against the docking valve 242, causing the docking valve 242 to always tend to move away from the mounting body 241. When the control valve assembly 24 is in a first open state, the docking valve 242 compresses the control spring 243 and rests against the mounting body 241, thereby cutting off the communication between the first oil outlet channel 21 and the oil reservoir 41. When the control valve assembly 24 is in a second open state, the docking valve 242 is pushed away from the mounting body 241 by the control spring 243, allowing the first oil outlet channel 21 to communicate with the connecting channel 2411.

[0041] Furthermore, one end of the docking valve 242 forms a plug end, and a check skirt 2421 is formed on the periphery of the plug end of the docking valve 242. When the control valve assembly 24 is in the first open state, the docking valve 242 compresses the control spring 243 and the plug end rests against the mounting body 241, thereby cutting off the connection between the first oil outlet channel 21 and the connecting channel 2411, and also cutting off the connection with the oil storage chamber 41. The check skirt 2421 is arranged in a contracted position under the oil pressure in the docking channel 23, so that the docking channel 23 is connected to the first oil outlet channel 21, realizing oil delivery (at this time, the state is as follows). Figure 6 ).

[0042] When the control valve assembly 24 is in the second open state, the plug end of the docking valve 242 is pushed away from the mounting body 241 by the control spring 243, thereby connecting the first oil outlet channel 21 with the connecting channel 2411. The oil in the first oil outlet channel 21 can then flow back to the oil storage chamber 41, achieving pressure relief. The check skirt 2421 opens, cutting off the connection between the docking channel 23 and the first oil outlet channel 21 (at this time, the state is as follows). Figure 7 ).

[0043] like Figure 6 As shown, the pump base 20 is also provided with a pressure regulating channel 25, which is connected to the docking channel 23. The pressure regulating channel 25 is equipped with a pressure regulating valve 26. By operating the pressure regulating valve 26, the oil pressure of the docking channel 23 can be adjusted to regulate the oil pressure in the channel and stabilize the oil circuit pressure.

[0044] like Figures 2 to 13As shown, the pump base 20 is also provided with a first pressure relief channel 27, which is connected to the connecting channel 2411. The fixed base 40 is provided with a second pressure relief channel 43, which is connected to the oil storage chamber 41. The first pressure relief channel 27 and the second pressure relief channel 43 are connected by a second mating connector 80, with both ends of the second mating connector 80 inserted into the first pressure relief channel 27 and the second pressure relief channel 43 respectively and sealed together.

[0045] After shutdown, the depressurized oil flows through the first depressurization channel 27 and the second depressurization channel 43. In this invention, the first depressurization channel 27 and the second depressurization channel 43 are sealed together using the second interlocking connector 80, which is a plug-in installation method. Therefore, this application adopts a three-point plug-in installation sealing connection scheme, including sealing the opening of the oil storage chamber 41 using the butt joint 22 and the first sealing member 60, sealing the first oil outlet channel 21 and the second oil outlet channel 42 using the first interlocking connector 70, and sealing the first depressurization channel 27 and the second depressurization channel 43 using the second interlocking connector 80. This abandons the traditional end-face assembly sealing scheme, effectively improving the equipment's adjustability, operational flexibility, and the ability to withstand vibration, unevenness, or misalignment to a certain extent.

[0046] like Figures 9 to 13 As shown in the embodiment provided by this utility model, the first mating connector 70 and the second mating connector 80 are selected as cylindrical structures with a certain length, whose height is much greater than that of commonly used O-rings. They can be applied to metal structures (such as copper, stainless steel, etc.) or non-metal structures (such as plastic, rubber, etc.). In this embodiment, the two ends of the first mating connector 70 are respectively inserted into the first oil outlet channel 21 and the second oil outlet channel 42, and the two ends of the second mating connector 80 are respectively inserted into the first pressure relief channel 27 and the second pressure relief channel 43, and are inserted to a certain depth, at which point they are not easily loosened. In order to ensure the sealing of the first mating connector 70 and the second mating connector 80, a second sealing element (selected as an O-ring, not shown in the figure) is fitted on the first mating connector 70. The first mating connector 70 is sealed and connected in the first oil outlet channel 21 and the second oil outlet channel 42 by means of the second sealing element. The second mating joint 80 is fitted with a third seal (selected as an O-ring, not shown in the figure). The second mating joint 80 is sealed in the first pressure relief channel 27 and the second pressure relief channel 43 by means of the third seal. It is worth noting that the second seal is not necessary. If the first mating joint 70 is sufficient to achieve a seal, then the second seal is not required. The same applies to the setting of the third seal, which will not be described further.

[0047] Depending on actual needs, in other implementation schemes, the first mating connector 70 and the second mating connector 80 can also be selected as O-rings. In this case, the O-rings can be specifically applied to have a structure with considerable height, so that the first mating connector 70 can be inserted into the first oil outlet channel 21 and the second oil outlet channel 42 at the same time to provide docking and sealing functions, and the second mating connector 80 can be inserted into the first pressure relief channel 27 and the second pressure relief channel 43 at the same time to provide docking and sealing functions.

[0048] The following is a brief description of the working process of the split-type electric gear lubrication pump 100 of this utility model: During the oiling operation, the motor 10 drives the gear pump 30 to operate. The gear pump 30 draws oil from the oil storage chamber 41 and first pumps it out to the docking channel 23. The oil pushes the docking valve 242, compressing the control spring 243, and the plug end of the docking valve 242 rests against the mounting body 241. The check skirt 2421 of the docking valve 242 is contracted under the pressure of the oil in the docking channel 23. The oil in the docking channel 23 flows into the first oil outlet channel 21, then into the second oil outlet channel 42, and is finally pumped out to the output pipeline. After the plug end rests against the mounting body 241, the connection between the first oil outlet channel 21 and the connecting channel 2411 is cut off. The oil also flows into the pressure regulating channel 25. When the oil in the channel is higher than the preset value, the pressure regulating valve 26 opens. At this time, the control valve assembly 24 is in the first open state. When oil supply stops, the connecting valve 242 is pushed by the control spring 243, causing the plug end to move away from the mounting body 241. The check skirt 2421 opens and cuts off the connection between the connecting channel 23 and the first oil outlet channel 21. The first oil outlet channel 21 is connected to the connecting channel 2411. The oil remaining in the second oil outlet channel 42, the first oil outlet channel 21 and the output pipeline flows into the connecting channel 2411, and then flows into the first pressure relief channel 27 and the second pressure relief channel 43, and finally flows back into the oil storage chamber 41. At this time, the control valve assembly 24 is in the second open state.

[0049] like Figure 1 As shown, the split-type electric gear lubrication pump 100 of this utility model also includes a control module 90 for performing overall control actions. The control module 90 can adopt an existing structure. In the embodiment provided by this utility model, the control module 90 is installed on the pump base 20, but it can also be installed on the fixed base 40 according to actual needs. In addition, an oil pressure gauge 01 is installed on the pump base 20, which is used to measure the oil pressure of the docking channel 23.

[0050] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
