Description

Technical Field

[0001] This utility model relates to the field of magnetic drive gear pump technology, specifically a magnetic drive gear pump with a heat-insulating jacket structure. Background Technology

[0002] During the operation of a magnetically driven gear pump, a thermal insulation jacket is required on the outside of the pump body to ensure fluid flow within the pump. This prevents heat loss from the pump body and thus reduces fluid flow. However, existing thermal insulation jackets require complete enclosure of the pump body, making installation inconvenient. Furthermore, the jackets only prevent heat loss, meaning that even in low ambient temperatures, the pump body temperature can still be affected. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a magnetically driven gear pump with an insulation jacket structure, which solves the problems of inconvenient installation of the insulation jacket and insufficient insulation at low temperatures.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetically driven gear pump with a heat-insulating jacket structure, comprising a pump body, a connecting column fixedly connected to the left end of the pump body, a connecting frame contacting the lower end of the pump body, a jacket cover hinged to the outer side of the connecting frame, an electric heating cover fixedly installed on the outer side of the jacket cover, an installation mechanism provided on the jacket cover, a screw fixedly connected to the lower end of the pump body, a bracket slidably connected to the outer side of the screw, a support ring fixedly connected to the outer side of the bracket, and a nut threadedly connected to the outer side of the screw.

[0005] Preferably, a motor is fixedly connected to the left end of the connecting column, and the output shaft of the motor is fixedly connected to the input shaft of the pump body, so that the motor can provide power to the pump body.

[0006] Preferably, the jacket cover is slidably connected to the pump body, and the jacket cover is slidably in contact with the connecting column, and the jacket cover can keep the pump body warm.

[0007] Preferably, the nut contacts the bracket, the bracket is slidably connected to the connecting frame, the support ring contacts the connecting frame, and the support ring can support the connecting frame.

[0008] Preferably, the installation mechanism includes a connecting seat, the upper end of the jacket cover is fixedly connected to the connecting seat, a U-shaped frame is slidably connected to the outside of the connecting seat, a hemispherical seat is slidably connected to the inside of the U-shaped frame, a spring is provided inside the U-shaped frame, a limit ring is fixedly connected inside the U-shaped frame, the hemispherical seat is engaged with the connecting seat, and the hemispherical seat can limit the U-shaped frame through the engagement with the connecting seat.

[0009] Preferably, one end of the spring is fixedly connected to the U-shaped frame, the other end of the spring is fixedly connected to the hemispherical seat, the limiting ring is slidably connected to the hemispherical seat, and the spring can automatically reset the hemispherical seat through its elastic force.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a connecting frame, support ring and installation mechanism to the pump body. During use, the jacket cover can be fitted onto the outside of the pump body through the hinge between the connecting frame and the jacket cover. Then, the jacket cover is limited by the sliding connection between the U-shaped frame and the connecting seat, which makes the insulation jacket easier to install.

[0012] 2. This utility model adds an electric heating cover to the outside of the jacket cover. When the ambient temperature is too low, the electric heating cover can supplement the heat of the pump body inside the jacket cover, thereby effectively preventing the fluid temperature inside the pump body from being too low.

The nut 11 is in contact with the bracket 9. The bracket 9 is slidably connected to the connecting frame 4. The support ring 10 is in contact with the connecting frame 4 and can support the connecting frame 4.

[0023] Please see Figure 1 , Figure 4 , Figure 6The installation mechanism 7 includes a connecting seat 71. The upper end of the jacket cover 5 is fixedly connected to the connecting seat 71. A U-shaped frame 72 is slidably connected to the outside of the connecting seat 71. A hemispherical seat 73 is slidably connected inside the U-shaped frame 72. A spring 74 is installed inside the U-shaped frame 72. A limit ring 75 is fixedly connected inside the U-shaped frame 72. The hemispherical seat 73 is snapped into the connecting seat 71.

[0024] The specific implementation process of this utility model is as follows: In use, the connecting frame 4 is sleeved on the outside of the screw 8, and then the bracket 9 is sleeved on the outside of the screw 8 and inserted into the inside of the connecting frame 4. After the connection is completed, the nut 11 is tightened. After the nut 11 is tightened, the connecting frame 4 can be stably installed on the outside of the pump body 1. Then, the jacket cover 5 hinged on the outside of the connecting frame 4 is flipped to the outside of the pump body 1, and the U-shaped frame 72 is inserted into the inside of the two adjacent connecting seats 71. During the insertion process, the connecting seat 71 pushes the hemispherical seat 73 to slide into the inside of the U-shaped frame 72 and compresses the spring 74. When the U-shaped frame 72 is completely slid into the inside of the connecting seat 71, the spring 74 returns to its original position. The spring 74 can drive the hemispherical seat 73 to be locked inside the connecting seat 71 by the elastic force, thus completing the limitation of the jacket cover 5. When the ambient temperature is low, the pump body 1 inside the jacket cover 5 can be heated by the electric heating cover 6.
