[0032] like Figure 1-8As shown, a centrifugal pump in this embodiment includes a base 1, a pump body 2, and a motor 3. The pump body 2 is located on the top of the base 1, and the motor 3 is located on one side of the pump body 2. The motor 3 is provided with a lifting lug 4. An execution system is provided inside the pump body 2, and the motor 3 is connected to the execution system in a transmission manner. The housing of the motor 3 is fixedly installed on the pump body 2. The pump body 2 is provided with an inlet 5 and an outlet 6. When the motor 3 is started, the execution system is activated, and the polymer melt or solution enters the pump body 2 from the inlet 5 and is discharged from the outlet 6, thereby realizing the transportation of the polymer melt or solution.

[0033] The base 1 is provided with a heat dissipation mechanism 7, which is used to dissipate heat from the motor 3.

[0034] The heat dissipation mechanism 7 includes a water tank 701 and a heat dissipation component 702. The motor 3, water tank 701, and base 1 are distributed from top to bottom. The water tank 701 is located on the top of the base 1. A gap is provided between the water tank 701 and the motor 3. The water tank 701 is connected to the motor 3 through the heat dissipation component 702. The water tank 701 is provided with an inlet 703 and an outlet 704. A partition 705 is provided inside the water tank 701. The partition 705 and the water tank 701 are integrally formed. The partition 705 divides the cavity inside the water tank 701 into an inlet cavity and an outlet cavity. The inlet 703 and the outlet 704 are respectively connected to the inlet cavity and the outlet cavity. A support block 706 is connected to one side of the water tank 701. The support block 706 abuts against the bottom of the motor 3. The support block 706 and the water tank 701 are detachably fixedly connected by a first screw 707.

[0035] The heat dissipation assembly 702 includes a heat dissipation pipe 7021 and two insertion holes 7022 disposed on the top of the water tank 701. The two insertion holes 7022 are respectively connected to the liquid inlet chamber and the liquid outlet chamber. The two ends of the heat dissipation pipe 7021 are respectively inserted into the two insertion holes 7022. The heat dissipation pipe 7021 slides and is sealed to the inner wall of the insertion hole 7022. The heat dissipation pipe 7021 is U-shaped. The heat dissipation pipe 7021 fits and passes around the top of the motor 3. The heat dissipation pipe 7021 is connected to the water tank 701.

[0036] In fact, the liquid inlet 703 is connected to the refrigerant supply system, and the liquid outlet 704 is connected to the refrigerant recovery system. During the start-up of the motor 3, the refrigerant is delivered from the liquid inlet 703 to the liquid inlet chamber through the refrigerant supply system. Here, the refrigerant is a coolant such as water or oil. The refrigerant in the liquid inlet chamber is then delivered to the liquid outlet chamber through the cooling pipe. The refrigerant in the liquid outlet chamber is then delivered to the refrigerant recovery system through the liquid outlet 704. The heat generated by the motor 3 is transferred to the refrigerant through the heat dissipation pipe 7021. In this way, the motor 3 is cooled. Compared with the blower-type cooling, the noise is reduced. Moreover, the refrigerant temperature is stable and less affected by the ambient temperature, which improves the heat dissipation effect of the motor 3.

[0037] Two heat dissipation components 702 are provided, and the two heat dissipation components 702 are symmetrically arranged about the lifting lug 4;

[0038] Multiple connecting rods 708 are fixedly installed on the top of the water tank 701. Each connecting rod 708 corresponds to a socket 7022. The connecting rods 708 are arranged vertically. A movable block 709 is sleeved on the connecting rod 708. The movable block 709 is fixedly installed on the heat dissipation pipe 7021. A nut 710 is threadedly connected to the connecting rod 708. The nut 710 abuts against the top of the movable block 709.

[0039] A spring 711 is sleeved on the connecting rod 708. The spring 711 is located between the moving block 709 and the water tank 701. The two ends of the spring 711 are connected to the moving block 709 and the water tank 701 respectively. A connecting block 712 is fixedly connected to the heat dissipation pipe 7021. The connecting block 712 is detachably fixedly connected to the housing of the motor 3 by a second screw 713.

[0040] When installing motor 3, first connect water tank 701, heat pipe 7021 and motor 3;

[0041] The connection sequence of water tank 701, heat dissipation pipe 7021 and motor 3 is as follows: First, the connecting block 712 is fixed to the housing of motor 3 by the second screw 713, thus realizing the fixed connection between heat dissipation pipe 7021 and motor 3. Then, the two ends of heat dissipation pipe 7021 are inserted into the corresponding sockets 7022. At the same time, the moving block 709 is sleeved on the connecting rod 708. Next, the nut 710 is screwed on and abuts against the top of the moving block 709. At this time, the spring 711 is in a free state, thus completing the connection of water tank 701, heat dissipation pipe 7021 and motor 3.

[0042] Next, the lifting lug 4 is connected to the lifting device, and the motor 3 is lifted and moved by the lifting device. When the water tank 701 is placed on top of the water tank 701, the motor 3 continues to move downward. At this time, due to gravity, the moving block 709 exerts a downward force on the spring 711, that is, the spring 711 is compressed. Through the elasticity of the spring 711, buffering is achieved, which protects the motor 3 and prevents the motor 3 from being damaged by excessive impact. When the motor 3 is against the support block 706, the motor 3 stops moving downward. Finally, the nut 710 is tightened, so that the nut 710 is against the moving block 709 and exerts a downward squeezing force on the moving block 709, thus completing the installation of the motor 3. In this way, the motor 3 is clamped, which improves the stability of the motor 3.

[0043] In summary, by absorbing the heat generated by the motor 3 through the refrigerant inside the heat pipe 7021, liquid cooling of the motor 3 is achieved, reducing noise. Moreover, the refrigerant temperature is stable and less affected by the ambient temperature, improving the heat dissipation effect of the motor 3. Secondly, the clamping of the motor 3 by the heat pipe 7021 improves the stability of the motor 3. In addition, during installation, the elasticity of the spring 711 can also buffer the motor 3, preventing damage from excessive impact force.

[0044] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
