Vertical gas circulating pump for new energy vulcanizing machine

The utility model provides a vertical gas circulating pump for a new energy vulcanizing machine, which comprises a frame body, a driving source, a balancing weight and a gas circulating pump arranged on the frame body, the gas circulating pump is provided with a pump body, a piston rod and a piston head are arranged in the pump body, and a gas inlet assembly and a gas outlet assembly are arranged outside the pump body. Wherein the driving source is connected with the piston rod, and the balancing weight is connected with the piston rod. The self-weight of moving parts such as the piston rod and the piston head is balanced by designing a balancing weight structure, so that the power output of a driving source is reduced, and the aim of saving energy is fulfilled; and the piston rod and the piston head are arranged to be of a cross-shaped structure, so that the suction amount and the discharge amount of a vulcanizing medium in a vulcanizing system pipeline are kept the same, and the technical effects of pressur
