The application discloses a gear box circulating cooling structure and cooling method for torque adjustment, relates to the field of gear box application, and comprises a base, the top of the base is provided with an input shaft, an output shaft, an intermediate shaft and a gear set, the outside of the input shaft, the output shaft and the intermediate shaft is provided with an oil injection assembly, the top of a middle cover is provided with an upper cover assembly, and the bottom of the upper cover assembly is provided with an oil sprinkling plate. The application sets two lubricating modes of lubricating oil sprinkling and lubricating oil spraying, can lubricate gears in different rotating speed stages, improves lubricating efficiency, when the gear box is cold started or driven at low speed, the oil sprinkling plate is used for oil sprinkling, when the rotating speed of the gear box increases, the centrifugal force of the oil injection assembly increases, the oil injection assembly is opened, and the lubricating oil is synchronously sprinkled and sprayed, and the sprayed lubricating oil is inclined, so that the lubricating oil can be better sprayed to the gear end face.

The utility model discloses a kind of gas-liquid mixed transmission synchronous self-priming pump structure, belong to self-priming pump technical field, comprising: centrifugal pump, its front end is provided with siphon tank, several steady flow baffle are provided in the siphon tank, exhaust port and water filling port are provided on the siphon tank, the siphon tank bottom is provided with drainage tube, liquid discharge pipe and liquid delivery pipe, the liquid delivery pipe is connected in the centrifugal pump water inlet;And gas-liquid separation chamber, it is connected at the centrifugal pump outlet.The utility model is by being provided with siphon tank, so that every time before starting does not need special water diversion operation, and also can achieve pump and simultaneously realize to send medium, ordinary self-priming pump after starting pump can only empty air and not self-priming time of water.
