A Structurally Coupled Multistage Pneumatic Power Machine

Abstract

The invention discloses a structurally coupled multi-stage pneumatic power machine, which includes an air storage tank, a volume type piston power mechanism, a speed type turbine power mechanism, a power coupling device and a control unit, and the volume type piston power mechanism and the speed type turbine power mechanism are respectively It communicates with the gas storage tank. A check valve is installed at the outlet of the gas storage tank. The volume piston power mechanism communicates with the speed turbine power mechanism. The volume piston power mechanism is connected with the power coupling device through the first output shaft. The speed turbine power mechanism The power mechanism is connected with the power coupling device through the second output shaft, and the control unit is respectively connected with the volume type piston power mechanism and the speed type turbine power mechanism. The beneficial effect of the present invention is to solve the problem that the single-cylinder reciprocating power machine has difficulty in starting up and down, and at the same time, it solves the problems of excessive exhaust pressure, incomplete expansion, and large loss, and improves the output power and energy of the piston power machine usage efficiency.

Description

technical field [0001] The invention relates to the technical field of pneumatic power machines, in particular to a structurally coupled multi-stage pneumatic power machine. Background technique [0002] At present, my country is a big energy-consuming country, and the demand for energy supply is increasing. The increase in energy demand is also accompanied by a series of energy-related problems, such as serious environmental pollution and gradually decreasing energy resources. Under the current circumstances, it is urgent to use new power drive devices to eliminate the dependence on fossil fuels. Among them, in the field of power machine technology, compressed air is used as the working medium and has no pollution to the atmospheric environment. Since the French engineer NEGRE first proposed the piston pneumatic The structure of the power machine and its application to aerodynamic vehicles have gradually attracted people's attention. [0003] However, so far, relevant rese...
