Description

Technical Field

[0001] This utility model relates to the field of oil pumps, and in particular to a connection device between an oil pump motor and an oil pump. Background Technology

[0002] An oil pump is a mechanical device used to transport oil. It has a wide range of applications in many fields. It can transport oil and also use its internal negative pressure to draw high-pressure oil back from the pipeline to the oil tank.

[0003] In existing technologies, for pipelines requiring oil return, a cooler needs to be installed outside the oil return pipeline and the oil tank connection pipeline to cool the returning oil. However, the cooler needs to be driven by a motor during operation, which occupies a large space. Furthermore, when working in special locations such as mines, if a motor is required, it also needs to be explosion-proofed, which increases the cost of equipment use. Therefore, a connection device based on an oil pump motor and an oil pump is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a connection device between an oil pump motor and an oil pump, which aims to improve the problem in the prior art that "when using a cooler for cooling, an additional motor needs to be installed, which will increase the cost of equipment use".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a connection device between an oil pump motor and an oil pump, comprising a housing, wherein a heat dissipation component is provided on the inner wall of the housing, and an oil cooler is inserted into the right surface of the housing;

[0006] The heat dissipation assembly includes an impeller, which is rotatably connected to the inner wall of the housing. The outer wall of the housing is provided with ventilation holes. A rear baffle is fixedly connected to the rear surface of the housing. A connecting flange is installed on the rear surface of the rear baffle. A coupling is installed on the rear surface of the impeller.

[0007] As a further description of the above technical solution:

[0008] The heat dissipation assembly also includes an air guide plate, which is fixedly connected to the inner wall of the housing.

[0009] As a further description of the above technical solution:

[0010] A support plate is installed on the inner wall of the housing, and a wind baffle is fixedly connected to the front surface of the support plate. An air inlet is provided on the wind baffle near the center.

[0011] As a further description of the above technical solution:

[0012] The rear surface of the air-guiding plate and the front surface of the wind baffle plate are attached to each other, and the middle position of the two can be combined to form an air-guiding cavity. The upper end of the air-guiding cavity is provided with an opening that coincides with the ventilation hole.

[0013] As a further description of the above technical solution:

[0014] A protective plate is fixedly connected to the inner wall of the ventilation hole.

[0015] As a further description of the above technical solution:

[0016] The front surface of the housing is provided with a slot for accommodating an oil cooler.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by additionally setting a set of impellers at the connection position between the oil pump and the oil pump motor, when the oil pump motor is working, its output shaft will drive the impeller and coupling to rotate synchronously. The rotation of the impeller will guide the airflow through the oil cooler. Then, by connecting the oil cooler to the outer wall of the return oil pipeline, the oil can be cooled by the oil cooler. The rotation of the coupling can transmit power to drive the oil pump to work. The overall device occupies less space and does not require an additional motor, resulting in lower operating costs.

[0019] 2. In this utility model, by setting an air-guiding plate and a baffle plate, the two can be fitted together to form an air-guiding cavity. The air-guiding cavity can guide the air to flow in a directional direction, so that the hot air can be stably discharged from the inside of the shell. This can prevent the heat dissipation effect from decreasing due to excessive retention of hot air, and the overall device has a good heat dissipation effect. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 This utility model provides an embodiment of a connection device between an oil pump motor and an oil pump, comprising a housing 2 for supporting the overall device, a heat dissipation component 3 for guiding airflow on the inner wall of the housing 2, and an oil cooler 1 inserted into the right surface of the housing 2. The oil cooler 1 is a prior art device with two sets of interfaces on its outer wall. During operation, these two sets of interfaces can be used to connect to the return oil pipeline, thus guiding the return oil through the interior of the oil cooler 1. The oil cooler 1 has an air duct inside, and when the airflow passes through the oil cooler 1, it can carry away the internal oil temperature to achieve cooling. The heat dissipation component 3 includes an impeller 31 for guiding airflow, and the impeller 31 is rotatably connected to the inner wall of the housing 2. The outer wall of the housing 2 is provided with ventilation holes 21 for discharging hot air. The rear surface of the housing 2 is fixedly connected to a rear baffle 25 for supporting the connecting flange 23. The connecting flange 23 is installed on the rear surface of the rear baffle 25. When in use, the connecting flange 23 can be directly connected to the flange on the outer wall of the oil pump, thus achieving the fixation of the entire device. The rear surface of the impeller 31 is equipped with a coupling 4 for transmitting power. The impeller 31 is directly installed on the outer wall of the motor output shaft, and one end of the coupling 4 is sleeved on the output end of the oil pump motor, and the other end is connected to the input end of the oil pump. Thus, when the oil pump motor is working, it will drive the impeller 31 and the coupling 4 to rotate simultaneously. The rotation of the coupling 4 will drive the oil pump output shaft to rotate.

[0029] Reference Figures 3-5The heat dissipation assembly 3 also includes an air guide plate 33 for guiding airflow. The air guide plate 33 is fixedly connected to the inner wall of the housing 2. The inner wall of the housing 2 is equipped with a support plate 26 for supporting the baffle plate 32. The baffle plate 32 is fixedly connected to the front surface of the support plate 26. The baffle plate 32 is provided with an air inlet 321 near the center. The air inlet 321 is concentric with the impeller 31 and the air inlet 321 corresponds to the inner ring shape of the impeller 31. After the rear surface of the air guide plate 33 and the front surface of the baffle plate 32 are attached, the middle position of the two can be combined to form an air guide cavity for guiding airflow. The upper end of the air guide cavity is provided with an opening that coincides with the ventilation hole 21.

[0030] Reference Figures 1-3 The inner wall of the ventilation hole 21 is fixedly connected with a protective plate 22 to block debris. The front surface of the housing 2 is provided with a slot 24 for accommodating the oil cooler 1. By providing the slot 24, the housing 2 and the oil cooler 1 can be further fitted together, and the overall size of the device can be further reduced.

[0031] Working principle: When the oil pump motor starts, the output shaft of the oil pump motor begins to rotate, which drives the coupling 4 and the impeller 31 to rotate synchronously. The rotation of the impeller 31 guides air through the middle position between the air intake plate 33 and the baffle plate 32, and guides the air to be discharged from the ventilation hole 21. As a result, the air pressure inside the housing 2 will decrease. At this time, the outside air will pass through the oil cooler 1 and enter the interior of the housing 2. When the air passes through the oil cooler 1, the oil can be cooled. Then the air will enter the air intake chamber through the air inlet 321 and move along the inner wall of the air intake chamber. Finally, it will be discharged from the inside of the device through the ventilation hole 21. The whole device does not require an additional motor to provide power when it is working, so the operating cost is low.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
