Abstract: The present application discloses a high-pressure diaphragm compressor. The high-pressure diaphragm compressor includes a gas-side diaphragm head and an oil-side diaphragm head; a diaphragm and an oil distribution disc are disposed between the gas-side diaphragm head and the oil-side diaphragm head, the diaphragm and the oil distribution disc are clamped between the gas-side diaphragm head and the oil-side diaphragm head, and a gas-side diaphragm cavity and an oil-side diaphragm cavity are respectively formed between the diaphragm and the gas-side diaphragm head as well as between the diaphragm and the oil distribution disc; an oil cylinder hole is provided in the oil-side diaphragm head, a piston is arranged in the oil cylinder hole, and a piston rod is disposed below the piston; and the upper end of the piston rod abuts onto the lower end of the piston, the piston may be separated from the piston rod.

Abstract: Disclosed is a logistics scheduling method and system for an industrial park based on a game theory. The method includes the following steps: establishing a logistics scheduling task model based on the game theory according to a relationship between warehouses and freight vehicles in logistics tasks; constructing an optimal decision model of each freight vehicle to maximize transportation income; constructing an optimal decision model of each warehouse to maximize warehousing income; and solving the optimal decision model of the freight vehicle to obtain an optimal decision for logistics scheduling. According to the present disclosure, the transportation efficiency is obviously improved, an empty return rate is reduced, and the real-time performance of the logistics tasks is not affected.
