A heavy-duty fast press

Abstract

The invention discloses a heavy-duty fast press, comprising a hydraulic push component, a nylon plug, a high-pressure tank, a high-pressure tank support component, a compression tube, a compression tube thrust component, a piston stop component, an experimental cabin assembly, and an experimental cabin support assembly. Nylon plugs, high-pressure tanks, compression pipes, piston stop components and experimental cabin components are arranged and connected in sequence to form a closed experimental device. The invention has compact layout and good sealing performance. The high-temperature and high-pressure environment is obtained in the experimental chamber through the high-speed heavy piston compressed air. The high-pressure tank in the equipment is arranged outside the compression pipe and is concentric with the compression pipe. The tubes are connected, the design of the compression tube thrust assembly can prevent the high-speed piston impact from driving the compression tube to move forward, and the setting of the piston anti-return assembly can obtain a stable high temperature and high pressure environment in the experimental cabin in a short time, and maintain various measurements in the experimental cabin. The stability and accuracy of the data, the setting of the experimental cabin support assembly prevents the compression tube from being deformed due to the excessive weight on the right end.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a heavy-duty fast press. Background technique [0002] The equipment is mainly used in the field of two-phase combustion. At present, the devices that provide a uniform high temperature and high pressure still gas environment mainly include reflection shock tubes and heavy piston drives. Compared with the shock wave non-isentropic compression method, the heavy piston driver performs approximately adiabatic isentropic compression of the gas, and the mechanical energy of the piston is converted into the internal energy of the compressed gas with high efficiency, which increases the gas temperature and pressure. Therefore, heavy piston drives are widely used in high-enthalpy ground simulation equipment such as expansion tubes and light gas guns. Used in conjunction with the piston backstop device, it constitutes a heavy piston driver with backstop control, which is ...

Problems solved by technology

In addition, most of the experimental chambers of existing equipment have small diameters and long combustion chambers, which limits the development of related research in large diameters and short combustion chambers.

At the same time, the equipment loss is serious during the experiment, and the safety is relatively poor. It is urgent to optimize the structure of the equipment.
