Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and in particular to a heat dissipation mechanism for a single screw pump. Background Technology

[0002] The single screw pump is a type of rotary positive displacement pump. It transports liquid by relying on the intermeshing of the screw and the bushing to create volume changes in the suction and discharge chambers. It is an internally meshing, closed screw pump. Its main working parts consist of a bushing (stator) with a double-headed helical cavity and a single-headed helical screw (rotor) that meshes with it in the stator cavity. This equipment is commonly used in oil extraction to transport sand-containing materials.

[0003] In existing technologies, during the operation of a single screw pump, the motor gradually accumulates heat over long periods. If this heat is not dissipated in time, it may affect the motor's output power. Furthermore, when conveying sandy materials, the friction between the material and the equipment in the output chamber also generates heat, posing a certain safety hazard. High temperatures can also cause the stator elastomer (usually made of rubber) to harden and age. High temperatures accelerate the aging process of rubber, making it hard, brittle, and inelastic, affecting the pump's sealing performance and service life. Thermal expansion of the stator can also lead to interference fit failure, reducing the interference between the stator and rotor, and worsening the sealing effect of the sealing chamber. The most direct manifestation is a decrease in the pump's volumetric efficiency and discharge pressure. Under extreme high temperatures, the rubber may undergo irreversible permanent deformation or even carbonization, leading to the complete failure of the stator. Therefore, a heat dissipation mechanism for single screw pumps is needed to meet these requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation mechanism for a single screw pump, in order to solve the problems mentioned in the background art, such as the gradual accumulation of heat in the motor during long-term operation, which may affect the output power of the motor if the heat is not dissipated in time, and the heat generated by the friction between the material and the equipment when the output chamber is conveying sandy materials, which poses certain safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation mechanism for a single screw pump, comprising a motor and a pump body, wherein a heat dissipation component one is arranged on the motor, a heat dissipation component two is arranged on the pump body, and a cooling box is arranged on one side of the motor, wherein the heat dissipation component one comprises two arc-shaped heat dissipation sleeves, the two arc-shaped heat dissipation sleeves covering the motor, and a plurality of heat dissipation fins are fixedly installed on the inner wall of the arc-shaped heat dissipation sleeves, and the same heat dissipation pipe passes through the plurality of heat dissipation fins.

[0006] Furthermore: a mounting base is fixedly installed at the bottom end of the arc-shaped heat dissipation sleeve, and a bolt is arranged between the mounting base and the base of the motor. A connecting strip is fixedly installed on the top side of the two arc-shaped heat dissipation sleeves, and a bolt is arranged between the two connecting strips.

[0007] Furthermore, a coolant input component and a coolant output component are fixedly installed at the top of the arc-shaped heat dissipation sleeve. The coolant input component and the coolant output component are respectively connected to the input and output ends of the heat dissipation fins.

[0008] Furthermore, the second heat dissipation component includes heat dissipation sleeve one, heat dissipation sleeve two, and heat dissipation sleeve three. Temperature sensors are fixedly installed on the side of heat dissipation sleeve one, heat dissipation sleeve two, and heat dissipation sleeve three near the pump body.

[0009] Furthermore: multiple partitions are fixedly and alternately arranged inside the heat dissipation sleeve one, and a coolant input component two and a coolant output component two are fixedly installed on the outside of the heat dissipation sleeve one. The coolant input component two and the coolant output component two are respectively connected to the input end and the output end of the partition. The heat dissipation sleeve one, heat dissipation sleeve two and heat dissipation sleeve three have the same structure.

[0010] Furthermore, a control terminal and a fan are fixedly installed on the cooling box, a cooling pipe is fixedly installed inside the cooling box, cooling fins are fixedly installed on the cooling pipe, the fan is compatible with the cooling pipe and cooling fins, and dustproof filter covers are arranged on both the fan and the cooling box.

[0011] Furthermore, the cooling chamber is also equipped with pump one and pump two, which are respectively connected to the coolant output terminals of heat dissipation component one and heat dissipation component two. The cooling chamber is also equipped with flow regulating pump one and flow regulating pump two, which are respectively connected to the coolant input terminals of heat dissipation component one and heat dissipation component two. Pump one, pump two, flow regulating pump one, and flow regulating pump two are respectively connected to both ends of the cooling pipe.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, heat dissipation component one and heat dissipation component two provide targeted heat dissipation for the two core heat-generating components: the motor and the pump body. The accumulated heat is efficiently carried away by circulating coolant. Both the motor and the pump body adopt an innovative segmented heat dissipation design. The motor part uses two arc-shaped heat dissipation sleeves, while the pump body part uses multiple heat dissipation sleeves to divide the heat dissipation. This effectively prevents the coolant from being heated too quickly when flowing through the heat source, thereby significantly improving the overall heat dissipation efficiency and ensuring the stability of the equipment during long-term operation.

[0014] In this invention, the coolant flow rate can be adjusted in real time based on the feedback from the temperature sensor through integrated control terminal, thereby achieving on-demand heat dissipation and reducing unnecessary energy consumption. It innovatively sets up an independent cooling box and uses an active heat dissipation system composed of a fan, cooling pipe and cooling fins to force-cool the returning hot coolant, quickly cooling it down and ensuring the circulating heat dissipation capacity of the coolant, thus forming an efficient and controllable closed-loop cooling system.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A heat dissipation mechanism for a single screw pump includes a motor 1 and a pump body 101. A heat dissipation component 1 2 is arranged on the motor 1, and a heat dissipation component 2 3 is arranged on the pump body 101. A cooling box 4 is arranged on one side of the motor 1. The heat dissipation component 1 2 includes two arc-shaped heat dissipation sleeves 201, which cover the motor 1. Several heat dissipation fins 202 are fixedly installed on the inner wall of the arc-shaped heat dissipation sleeves 201, and the same heat dissipation pipe 203 passes through the several heat dissipation fins 202.

[0023] In an optional embodiment: a mounting base 204 is fixedly installed at the bottom end of the arc-shaped heat dissipation sleeve 201, and a bolt 205 is arranged between the mounting base 204 and the base of the motor 1. A connecting strip 206 is fixedly installed on the top side of the two arc-shaped heat dissipation sleeves 201, and a bolt 207 is arranged between the two connecting strips 206.

[0024] It should be noted that the mounting base 204 and the connecting strip 206 cooperate to fix the arc-shaped heat dissipation sleeve 201 onto the motor 1.

[0025] In an optional embodiment: a coolant input component 208 and a coolant output component 209 are fixedly installed on the top of the arc-shaped heat dissipation sleeve 201, and the coolant input component 208 and the coolant output component 209 are respectively connected to the input and output terminals of the heat dissipation fins 202.

[0026] It should be noted that the coolant inlet component 208 and the coolant outlet component 209 work together to input and output coolant to the heat sink fins 202.

[0027] In an optional embodiment: the heat dissipation component 2 3 includes heat dissipation sleeve 1 301, heat dissipation sleeve 2 302, and heat dissipation sleeve 303. Temperature sensors 304 are fixedly installed on the side of heat dissipation sleeve 1 301, heat dissipation sleeve 2 302, and heat dissipation sleeve 303 near the pump body 101.

[0028] It should be noted that the heat dissipation sleeves 1 (301), 2 (302), and 3 (303) work together to dissipate heat from a portion of the pump body 101, which also helps to prevent the coolant from heating up too early. The temperature sensor 304 can detect the heat in each part and adjust the coolant flow rate in time to avoid wasting resources.

[0029] In an optional embodiment: multiple partitions 305 are fixedly and alternately arranged inside the heat dissipation sleeve 301, and a coolant input component 306 and a coolant output component 307 are fixedly installed outside the heat dissipation sleeve 301. The coolant input component 306 and the coolant output component 307 are respectively connected to the input end and the output end of the partition 305. The heat dissipation sleeve 301, heat dissipation sleeve 302, and heat dissipation sleeve 303 have the same structure.

[0030] It should be noted that the heat dissipation sleeve 301 is divided into an S-shaped flow channel by a partition 305, which works in conjunction with the coolant inlet component 306 and the coolant outlet component 307 to achieve heat dissipation.

[0031] In an optional embodiment: a control terminal 401 and a fan 402 are fixedly installed on the cooling box 4, a cooling pipe 403 is fixedly installed inside the cooling box 4, a cooling fin 404 is fixedly installed on the cooling pipe 403, the fan 402 is adapted to the cooling pipe 403 and the cooling fin 404, and a dustproof filter cover 409 is arranged on both the fan 402 and the cooling box 4.

[0032] It should be noted that the cooling box 4 mainly uses the fan 402 to generate airflow, which, together with the cooling pipe 403 and cooling fins 404, removes heat from the coolant.

[0033] In an optional embodiment: the cooling chamber 4 is further equipped with a first pump 405 and a second pump 406, which are respectively connected to the coolant output terminals of the first heat dissipation component 2 and the second heat dissipation component 3. The cooling chamber 4 is also equipped with a first flow regulating pump 407 and a second flow regulating pump 408, which are respectively connected to the coolant input terminals of the first heat dissipation component 2 and the second heat dissipation component 3. The first pump 405, the second pump 406, the first flow regulating pump 407, and the second flow regulating pump 408 are respectively connected to both ends of the cooling pipe 403.

[0034] It should be noted that pump 1 405 and pump 2 406 deliver hot liquid, while diversion regulating pump 1 407 and diversion regulating pump 2 408 deliver cool liquid, which works in conjunction with the heat dissipation components 1 2 and 2 3 on the motor 1 and pump body 101 to dissipate heat.

[0035] Working principle of this utility model:

[0036] Using this equipment, the cooling box (section 4) primarily uses fan 402 to generate airflow, which, in conjunction with cooling pipes 403 and cooling fins 404, removes heat from the coolant. This allows pumps 405 and 406 to deliver hot liquid, while flow regulating pumps 407 and 408 deliver cool liquid. This cool liquid, along with heat dissipation components 2 and 3 on motor 1 and pump body 101, dissipates heat. In heat dissipation component 2, the hot liquid enters the coolant inlet 208 through a pipeline and then flows into the heat dissipation pipe 203, where it works with the heat dissipation fins 202 to absorb heat from motor 1. The coolant is then delivered through the coolant outlet 209. The two arc-shaped heat dissipation sleeves 201 work together to prevent the coolant from heating up too early and reducing the heat dissipation effect. In the heat dissipation component 2 3, the heat dissipation sleeves 1 301, 2 302, and 3 303 work together to dissipate heat from a part of the pump body 101, which can also prevent the coolant from heating up too early. The temperature sensor 304 can detect the heat of each part and adjust the coolant flow rate in time to avoid wasting resources. Inside the heat dissipation sleeve 1 301, the partition 305 divides the flow channel into an S-shaped flow channel to cooperate with the coolant inlet component 2 306 and the coolant outlet component 2 307 to achieve heat dissipation.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
