However, due to the high temperature of heating furnace working environment, and the servo motor will generate a lot of heat in the running process itself, if not timely and effective heat dissipation, the performance of motor will be seriously affected, such as efficiency reduction, short service life or even failure. Energy-saving servo motor can accurately control the speed and torque according to the actual working condition, so as to realize the purpose of energy saving.

The impurities in the air-cooled motor are easy to enter the motor, adhere to the winding, bearing and other parts of the motor, accelerate the wear and corrosion of the parts. For example, dust accumulation on the winding will affect the heat dissipation effect, and may cause the winding insulation performance to decline, causing short circuit failure. Corrosive gas will corrode the metal parts of the motor, shorten the service life of the motor. Therefore, a new type of efficient, reliable and easy-to-maintain water cooling device is needed to ensure the stable operation of energy-saving servo motor in the hydraulic system of heating furnace.

One end of the inner side of the heat-conducting fins 14 is fixedly connected to the housing of the servo motor 1, and several through holes are provided on the heat-conducting fins 14. These through holes correspond to the heat-absorbing copper tubes 15 and are fixedly fitted to them. A sealing sleeve 13 is connected to the outer sealing sleeve of the heat-conducting fin 14 and the heat-absorbing copper tube 15; the two ends of the heat-absorbing copper tube 15 are fixedly connected to the first conduit 5, which passes through the sealing sleeve 13 and the protective shell 2, and a first heat insulation sleeve 4 is fixedly sleeved at the outer end. The lower end of the first heat insulation sleeve 4 is fixedly connected to the protective shell 2. A temperature sensing probe 16 is fixedly installed on the inner side of the sealing sleeve 13. A wire 6 is electrically connected to the temperature sensing probe 16. The wire 6 passes through the center of the first heat insulation sleeve 4 and is fixedly sleeved thereto. The wire 6 is also electrically connected to an external controller.

[0025] In this configuration, the efficiency of heat conduction and heat absorption is increased by combining the heat-conducting fins 14 and the heat-absorbing copper tubes 15; a sealing sleeve 13 is added to the periphery of the heat absorption mechanism to prevent leakage from causing a circuit break in the motor; the function of the heat dissipation grille 3 is to assist in heat dissipation and prevent heat accumulation inside the protective shell 2, rather than to actively dissipate heat.

[0026] like Figures 1 to 8 As shown, in a specific embodiment, a heat dissipation mechanism is provided inside the radiator housing 7. The heat dissipation mechanism includes several heat dissipation fins 17 and heat dissipation copper pipes 19. Several through holes are opened on the heat dissipation fins 17, which correspond to the heat dissipation copper pipes 19 and are fixedly sleeved with them. The heat dissipation copper pipes 19 penetrate the radiator housing 7 and a third heat insulation sleeve 9 is fixedly sleeved at the outer end.

Several air inlet grilles 12 are opened on the other side of the radiator housing 7.

[0029] In the present arrangement, the heat insulation sleeve prevents the high temperature outside from affecting the temperature in the pipe.

[0030] The implementation principle of the energy-saving servo motor of the heating furnace hydraulic system in the embodiment is as follows:

[0031] The servo motor 1 is cooled by the water cooling and radiator mode, which can avoid the problem of internal dust accumulation caused by air cooling, and the heat conduction and heat absorption efficiency is increased by the combination of the heat conduction sheet 14 and the heat absorption copper pipe 15; furthermore, the sealing sleeve 13 is additionally arranged on the periphery of the heat absorption mechanism to prevent the liquid leakage from causing the circuit breakage of the motor; the heat dissipation grid 3 plays a role in assisting heat dissipation and preventing the heat accumulation in the protective shell 2, and is not the active heat dissipation, and the heat insulation sleeve prevents the high temperature outside from affecting the temperature in the pipe.
