Abstract

PURPOSE: To prevent heating of a system of rotors not only upon starting of a pump but also during operations of the pump under noload or low-load condition and secure safety of the pump by a method wherein priming liquid is supplied to the pump automatically.
CONSTITUTION: This priming liquid circulating device is constituted by connecting the other end of a priming liquid supplying tube 13, one end of which is connected to a proper place of a casing 2 of a rotary pump 1, to a priming liquid tank 12 while communicating the other end of a priming liquid recirculating tube 14, one end of which is connected to said tank 12, with a discharging port 7 of said casing 2. According to these connections, the operation of the pump 1 unddr circulating the priming liquid automatically is enabled and rotors such as gears and the like in the casing 2 are immersed in the priming liquid continuously due to a continuous supply of the priming liquid into the casing 2, therefore, heating of the rotors may be prevented even if the rotors are made of a synthetic resin, accordingly, damages of the pump 1 due to heating of a sysgem of the rotors may be prevented effectively.
