Description

Technical Field

[0001] This utility model relates to the field of gear pump equipment technology, and in particular to a gear pump oil discharge housing structure. Background Technology

[0002] A gear pump is a rotary pump that transports or pressurizes liquids by relying on the change and movement of the working volume formed between the pump cylinder and meshing gears. It consists of two gears, a pump body, and front and rear covers forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side of the gears increases from small to large, creating a vacuum that draws in the liquid. Conversely, the volume of the space on the meshing side of the gears decreases from large to small, forcing the liquid into the pipeline.

[0003] In practical applications, the existing gear pump drain housing has a relatively limited function, only serving as an auxiliary installation device. It cannot provide adequate cooling during equipment operation, resulting in the equipment being in a high-temperature state for extended periods. Over time, this can easily cause varying degrees of damage and lead to numerous inconveniences.

[0004] Therefore, this utility model provides a gear pump oil discharge housing structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a gear pump oil discharge housing structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a gear pump oil discharge housing structure, including a gear pump mounting base,

[0007] A first oil sump is installed on one side of the gear pump mounting base, and a second oil sump is installed on the other side of the gear pump mounting base. A gear is rotatably connected to the side of the second oil sump closer to the gear pump mounting base, and a drive mechanism is installed on the side of the second oil sump away from the gear pump mounting base.

[0008] A heat dissipation mechanism is installed inside the first oil drain housing. The heat dissipation mechanism includes a positioning frame. A positioning frame is installed inside the first oil drain housing. A second mounting frame is installed on the side of the positioning frame near the gear pump mounting base. A first mounting frame is installed on the side of the positioning frame away from the second mounting frame. A radiator extending to the outside of the first oil drain housing is installed on the outside of the first mounting frame. Equally spaced exhaust pipes are installed on the top of the positioning frame. A positioning side plate is installed on the outside of the radiator. One end of each of the exhaust pipes passes through the positioning side plate and extends to the bottom of the radiator. A fan is installed inside the second mounting frame. A rotating motor is fixedly connected to one side of the fan. The output end of the rotating motor is fixedly connected to the fan. The fan is a bidirectional fan structure, which facilitates the extraction of high-temperature gas inside the gear pump mounting base and the delivery of hot gas to the inside of the positioning frame. Multiple first heat dissipation fins assist in primary heat dissipation. The exhaust pipes deliver some of the high-temperature gas to the inside of the radiator, where multiple second heat dissipation fins assist in secondary heat dissipation, thereby extending the service life of the internal equipment.

[0009] In a preferred embodiment, the radiator has equidistantly distributed second heat dissipation fins installed inside, and the positioning frame has equidistantly distributed first heat dissipation fins installed inside. Heat is dissipated by the primary absorption of heat by multiple first heat dissipation fins and by the secondary absorption of heat by multiple second heat dissipation fins. Positioning plates are installed on both sides of the positioning side plate, and each of the two positioning plates is threaded with a first positioning bolt extending into the radiator. Second positioning bolts extending into the positioning frame are threaded around the outer perimeter of the first mounting frame. The first mounting frame and the positioning frame are reinforced by multiple second positioning bolts, and the positioning side plate and the first mounting frame are reinforced by the positioning plates and the first positioning bolts, facilitating quick disassembly and assembly during maintenance.

[0010] In a preferred embodiment, the gear pump mounting base has an internal mounting groove, and a limiting shaft is installed inside the internal mounting groove. One end of the limiting shaft is fixedly connected to the gear. There are two internal mounting grooves, and gears with the same structure can be installed on one side of the gear to cooperate with the corresponding internal mounting grooves. The first oil drain housing has an internal mounting cavity for mounting with a positioning frame. The cooling mechanism is normally installed through the internal mounting cavity inside the first oil drain housing. The drive mechanism includes a transmission belt. The transmission belt is installed on the side of the second oil drain housing away from the gear pump mounting base. A driven pulley and a driving pulley are rotatably connected inside the transmission belt. The driving pulley is located on one side of the driving pulley. The driven pulley is connected to the driving pulley through the transmission belt. A mounting cover is installed on one side of the transmission belt. A drive motor is fixedly connected inside the mounting cover. The output end of the drive motor is fixedly connected to the driving pulley. One side of the mounting cover is connected to the first oil drain housing, thereby ensuring the positioning and installation of the drive mechanism and ensuring the normal operation stability of the equipment.

[0011] In a preferred embodiment, a main control board is installed inside the mounting cover, and a control chip is fixedly connected to the outside of the main control board. The drive motor and the fan are both electrically connected to the control chip. The control chip is used to control the operation of the drive motor and the fan, realizing unified management of the power equipment. The overall equipment does not use a large number of power equipment to assist in operation, saving the overall use and installation costs.

[0012] In a preferred embodiment, a top mounting block is installed on the top of the gear pump mounting base. Two external pipes are installed on one side of the top mounting block, and a top mounting block is installed at the connection point of the two external pipes. One of the external pipes is located on one side of the first oil pan, and the other external pipe is located on the top of the gear pump mounting base. A sealing plug is installed at the bottom of one of the external pipes. When not in operation, the sealing plug is used to seal one of the external pipes, replacing the high-cost consumption of valves. By installing a protective sleeve between the two external pipes, the connection effect is achieved while improving the sealing performance.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] By incorporating a first oil sump, a gear pump mounting base, a heat dissipation mechanism, and a second oil sump, and using a bidirectional fan structure, the system facilitates the extraction of high-temperature gas from the gear pump mounting base and transfers the hot gas to the positioning frame. Multiple first heat dissipation fins assist in primary heat dissipation, while an exhaust pipe transports some of the high-temperature gas to the radiator for secondary heat dissipation via multiple second heat dissipation fins. This extends the service life of the internal equipment. The system utilizes multiple first heat dissipation fins for primary heat absorption and multiple second heat dissipation fins for secondary heat absorption. Multiple second positioning bolts reinforce the connection between the first mounting frame and the positioning frame, while positioning plates and first positioning bolts reinforce the positioning side plate and the first mounting frame, facilitating quick disassembly and assembly during maintenance. One side of the cover is connected to the first row of oil tanks, thus ensuring the positioning and installation of the drive mechanism and guaranteeing the normal operation stability of the equipment. One end of the limit shaft is connected to the driven pulley. The drive motor rotates, which in turn drives the corresponding drive pulley to rotate. Through the transmission belt, the driven pulley rotates, thereby driving the limit shaft on one side to rotate, which in turn drives the corresponding gear to rotate, coordinating with subsequent oil delivery operations. The entire equipment does not use a large amount of electrical equipment to assist in operation, saving overall usage and installation costs. A sealing plug is installed at the bottom of one of the external pipes. When not in operation, the sealing plug is used to seal one of the external pipes, replacing the high-cost consumption of valves.

The control chip is used to control the operation of the drive motor 36 and the fan 44, realizing unified management of electrical equipment. The overall equipment does not use a large number of electrical equipment to assist in operation, saving the overall use and installation costs.

[0034] Going further, such as Figures 1-3 As shown, in this scheme, a top mounting block 23 is installed on the top of the gear pump mounting base 2. Two external pipes 21 are installed on one side of the top mounting block 23. The top mounting block 23 is installed at the connection point of the two external pipes 21. One external pipe 21 is located on one side of the first oil tank 1, and the other external pipe 21 is located on the top of the gear pump mounting base 2.
