Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer oil pumps, in particular to a heat transfer oil pump with good sealing performance. Background Art

[0002] The thermal oil pump is an ideal hot oil circulation pump or heat carrier delivery pump. It is an ideal matching pump for heat exchange equipment and is widely used in various industrial fields such as petrochemical, rubber and plastic, food and pharmaceutical, textile printing and dyeing;

[0003] At present, there is an existing thermal oil pump with good sealing performance (such as patent number: CN211174622U), which discloses that a cooling device is arranged under the pump head and the rotor, and air is introduced into the interior through an air inlet pipe to achieve the purpose of cooling the pump head, thereby improving the sealing performance of the pump head. The cooling device is arranged in a semi-arc shape and a cooling port is opened perpendicular to the length direction of the cooling device, so that the pump head can be cooled over a large area.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: although the pump head position can be cooled to prevent leakage, the device uses a sealing rubber ring for sealing when connecting the oil pump turbine pipeline with the external pipeline. Although the sealing rubber ring can be sealed, it is made of soft rubber and is prone to rot after being used for too long, resulting in a lack of stability, which in turn causes leakage at the joints of the device during use.

Although the sealing rubber ring can be sealed, since the material of the sealing rubber ring is soft rubber, it is easy to rot after being used for too long, thereby lacking stability, which in turn leads to the technical problem that the device is prone to leakage at the joints during use.

[0026] The embodiment of the present application provides a heat-conducting oil pump with good sealing performance, which effectively solves the problem that although the pump head position can be cooled to prevent leakage, the device uses a sealing rubber ring for sealing when connecting the oil pump turbine pipeline with the external pipeline. Although the sealing rubber ring can be sealed, since the sealing rubber ring is made of soft rubber, it is easy to rot after a long time of use, thereby lacking stability, which leads to the device being prone to leakage at the joint during use. The new type of device is provided with annular grooves on the circumferential surfaces of the upper and lower ends of the flange, and then an upper piston ring is arranged inside the annular groove. Through the elastic force of the piston ring and the piston ring being installed on the circumferential inner wall of the flange, the oil pump turbine and the upper connecting pipe, the piston ring can be completely fitted with the circumferential inner wall of the upper connecting pipe and the oil pump turbine, thereby effectively sealing the oil passing through the oil pump turbine and the upper connecting pipe without leakage. Since the piston ring is made of metal, it will not rot like a rubber ring after long-term use, thereby avoiding oil leakage of the device over a long period of time.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that although the temperature at the pump head position can be reduced to prevent leakage, the device uses a sealing rubber ring for sealing when connecting the oil pump turbine pipeline with the external pipeline. Although the sealing rubber ring can be sealed, the material of the sealing rubber ring is soft rubber, which is prone to rot after a long time of use, thereby lacking stability, and thus causing the device to leak easily at the joint during use. The overall idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides a heat-conducting oil pump with good sealing performance, including a mounting base 31, a motor 32 is provided at the upper end of the mounting base 31, a coupling 35 is provided at the right end of the motor 32, a heat-conducting component 34 is provided at the right end of the coupling 35, an oil pump turbine 33 is provided at the right end of the heat-conducting component 34, an upper connecting pipe 24 is provided at the upper end of the oil pump turbine 33, a flange 11 is provided between the oil pump turbine 33 and the upper connecting pipe 24, six guide columns 12 are fixedly installed at the upper and lower ends of the flange 11, annular grooves 13 are provided on the circumferential surfaces of the upper and lower ends of the flange 11, and the flange 11 is provided with a plurality of guide posts 12 ... 1 are provided with piston rings 16 for strengthening the interface seal, and the circumferential surfaces of the two piston rings 16 are provided with bayonet holes 15. When installing the upper connecting pipe 24 and the oil pump turbine 33, the user inserts the two sealing rubber rings 14 into the circumferential surfaces of the upper and lower ends of the flange 11 respectively, and then the user inserts the two piston rings 16 into the annular grooves 13 provided in the flange 11 through the bayonet holes 15. Then the user can place the flange 11 above the pipeline of the oil pump turbine 33, and then insert the six guide pillars 12 at the lower end of the flange 11 into the oil pump turbine 33, and then Insert the upper connecting pipe 24 from the upper end of the flange 11. At this time, the six guide columns 12 at the upper end of the flange 11 will penetrate and be inserted into the pipe above the upper connecting pipe 24. Then, the upper connecting pipe 24 and the oil pump turbine 33 are pressed together. At this time, the user can install the six U-shaped mounting blocks 21, and insert the opening of the U-shaped mounting block 21 against the adjacent ports of the upper connecting pipe 24 and the oil pump turbine 33. At this time, the U-shaped mounting block 21 will be sleeved on the circumferential surface of the guide columns 12 at the upper and lower ends of the flange 11 through the two positioning grooves 22. The piston ring 16 arranged between the ends is elastic, so when the U-shaped mounting block 21 is installed, the piston ring 16 will be clamped, so that the upper connecting pipe 24 and the oil pump turbine 33 can be more tightly connected with the flange 11, and then the user installs the remaining U-shaped mounting blocks 21 at a time. After the installation is completed, the user puts the locking ring 25 between each U-shaped mounting block 21 and the L-shaped plate 23. Since the shape of the L-shaped plate 23 can form a groove with the U-shaped mounting block 21, the locking ring 25 can be installed, and the installation of the locking ring 25 can effectively prevent the six U-shaped mounting blocks 21 from falling.

[0030] The upper and lower circumferential surfaces of the flange 11 are sleeved with sealing rubber rings 14 for sealing the upper connecting pipe 24 and the oil pump turbine 33. The flange 11 is installed in the upper connecting pipe 24 and the oil pump turbine 33 through the guide columns 12 at the upper and lower ends. The circumferential surfaces of the upper connecting pipe 24 and the oil pump turbine 33 are provided with six U-shaped mounting blocks 21, and the side ends of each U-shaped mounting block 21 are fixedly installed with an L-shaped plate 23. The side ends of each U-shaped mounting block 21 are provided with a positioning groove 22. Each U-shaped mounting block 21 is sleeved on the circumferential surfaces of the guide columns 12 at the upper and lower ends of the flange 11 through the opened positioning groove 22. The outer surfaces of the six U-shaped mounting blocks 21 are sleeved with locking rings 25, and the locking rings 25 are arranged between each U-shaped mounting block 21 and the L-shaped plate 23. The device is formed by opening annular grooves 13 on the circumferential surfaces of the upper and lower ends of the flange 11, and then an upper piston ring 16 is arranged inside the opened annular groove 13. Through the elastic force of the piston ring 16 and the piston ring 16 is installed on the flange 11 and the circumferential inner wall of the oil pump turbine 33 and the upper connecting pipe 24, so that the piston ring 16 can be completely fitted with the circumferential inner wall of the upper connecting pipe 24 and the oil pump turbine 33, thereby effectively sealing the oil passing through the oil pump turbine 33 and the upper connecting pipe 24 without leakage. Since the piston ring 16 is made of metal, it will not rot like a rubber ring after long-term use, thereby avoiding oil leakage in the device over a long period of time. At the same time, the device can install the upper connecting pipe 24 and the oil pump turbine 33 through the U-shaped mounting block 21 through the six U-shaped mounting blocks 21 and the positioning grooves 22 opened by the U-shaped mounting block 21. Moreover, when the U-shaped mounting block 21 is removed from between the upper connecting pipe 24 and the oil pump turbine 33, it can be operated very simply without the need for cumbersome operations such as using tools, thereby effectively improving the installation and removal efficiency of the upper connecting pipe 24 and the oil pump turbine 33.

[0031] Working principle:

[0032] In the first step, when the device is installing the upper connecting pipe 24 and the oil pump turbine 33, the user now inserts the two sealing rubber rings 14 into the upper and lower circumferential surfaces of the flange 11 respectively, and then the user inserts the two piston rings 16 into the annular grooves 13 opened in the flange 11 through the opened bayonet 15. After that, the user can place the flange 11 above the pipeline of the oil pump turbine 33, and then insert the six guide columns 12 at the lower end of the flange 11 into the oil pump turbine 33, and then insert the upper connecting pipe 24 from the upper end of the flange 11. At this time, the six guide columns 12 at the upper end of the flange 11 will penetrate and be inserted into the pipeline above the upper connecting pipe 24, and then the upper connecting pipe 24 and the oil pump turbine 33 will be fitted and pressed. At this time, the user can install the six U-shaped mounting blocks 21, and the opening of the U-shaped mounting block 21 is facing the upper connecting pipe 24 and the oil pump turbine The U-shaped mounting block 21 is inserted into the port adjacent to the wheel 33. At this time, the U-shaped mounting block 21 will be sleeved on the circumferential surface of the guide column 12 at the upper and lower ends of the flange 11 through the two positioning grooves 22. Since the piston ring 16 arranged between the upper connecting pipe 24 and the oil pump turbine 33 and the upper and lower ends of the flange 11 is elastic, the piston ring 16 will be clamped when the U-shaped mounting block 21 is installed, so that the connection between the upper connecting pipe 24 and the oil pump turbine 33 and the flange 11 can be tighter. Then the user installs the remaining U-shaped mounting blocks 21 at one time. After the installation is completed, the user sleeves the locking ring 25 between each U-shaped mounting block 21 and the L-shaped plate 23. Since the shape of the L-shaped plate 23 can form a slot with the U-shaped mounting block 21, the locking ring 25 can be installed, and the installation of the locking ring 25 can effectively prevent the six U-shaped mounting blocks 21 from falling off.

[0033] In the second step, the device is provided with annular grooves 13 on the circumferential surfaces of the upper and lower ends of the flange 11, and then an upper piston ring 16 is arranged inside the annular grooves 13. Through the elastic force of the piston ring 16 and the piston ring 16 being installed on the circumferential inner walls of the flange 11, the oil pump turbine 33 and the upper connecting pipe 24, the piston ring 16 can be completely fitted with the circumferential inner walls of the upper connecting pipe 24 and the oil pump turbine 33, thereby effectively sealing the oil passing through the oil pump turbine 33 and the upper connecting pipe 24 without leakage. Since the material of the piston ring 16 is metal, After long-term use, it will not rot like a rubber ring, thus avoiding oil leakage of the device over a long period of time. At the same time, the device can install the upper connecting pipe 24 and the oil pump turbine 33 through the U-shaped mounting block 21 by means of the six U-shaped mounting blocks 21 and the positioning grooves 22 provided on the U-shaped mounting blocks 21. Moreover, when the U-shaped mounting block 21 is removed from between the upper connecting pipe 24 and the oil pump turbine 33, the operation can be performed very simply without the need for cumbersome operations such as using tools, thereby effectively improving the installation and disassembly efficiency of the upper connecting pipe 24 and the oil pump turbine 33.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
