An output shaft of the motor 12 is connected to a second end of the transmission shaft 11 and is used for driving the transmission shaft 11 to rotate. The mechanical sealing device 20 is disposed on the transmission shaft 11 and is connected to the transmission shaft 11 in a sealing manner. The mechanical sealing device 20 is connected with the pump body 10 in a sealing manner and is used for preventing the process medium in the pump body 10 from leaking.
The cooling liquid inlet pipe 31 is communicated with the cavity of the mechanical sealing device 20 and is used for injecting cooling liquid into the cavity of the mechanical sealing device 20. The coolant outlet pipe 32 is communicated with the cavity of the mechanical sealing device 20 and is used for discharging the coolant in the cavity of the mechanical sealing device 20. The buffer tank 40 is in communication with the coolant inlet pipe 31 and the coolant outlet pipe 32, and is used to store the coolant. The buffer tank 40 is a normal pressure tank, and a heat exchange device 41 for cooling the coolant in the buffer tank 40 is provided in the tank.

In this embodiment, can only add the coolant liquid of fixed liquid level, fixed capacity in the buffer tank 40, convenient operation, swift moreover, operating personnel only need pay close attention to overflow mouth 403 when adding the coolant liquid can, operating personnel also need not too much pay close attention to the liquid level change in the buffer tank 40 when normal production, the actual production of being convenient for is used. In addition, the electronic control elements such as a liquid level sensor and the like are not needed in the embodiment, so that the processing cost is low, and the installation is convenient.
Specifically, the aspect ratio of the buffer tank 40 is greater than 5: 1. Buffer tank 40 adopts bigger draw ratio, can be more sensitive to the change of liquid level height, combines the position setting to liquid outlet 401 and overflow mouth 403, can the effective control coolant liquid safety risk of leaking. In practical applications, the cooling liquid between the liquid outlet 401 and the overflow 403 is typically 50 ml to 500 ml.
