Pneumatic position servosystem

Abstract

A pneumatic position servosystem comprises a water-gas separator, a first emulsion barrel, a second emulsion barrel, a first cylinder and a second cylinder. The water-gas separator is connected with the first emulsion barrel through a first pipeline, and a first two-position four-way valve and a first pneumatic control valve are arranged on the first pipeline; the water-gas separator is connected with the second emulsion barrel through a second pipeline, and a second two-position four-way valve and a second pneumatic control valve are arranged on the second pipeline. The first pneumatic control valve is connected with the second pipeline through a second gas pipe, and the second pneumatic control valve is connected with the first pipeline through a first gas pipe. The first cylinder is connected with the first emulsion barrel through a third pipeline, and the third pipeline is connected to the upper portion of the first cylinder and inserted into emulsion in the first emulsion barrel. The second cylinder is connected with the second emulsion barrel through a fourth pipeline, and the fourth pipeline is connected to the lower portion of the second cylinder and inserted into emulsion in the second emulsion barrel. The pneumatic position servosystem can adapt to a large-torsion-change environment and is high in response speed and reliability and suitable for an organic solvent evaporation environment.

Description

technical field [0001] The invention relates to a pneumatic position following system. Background technique [0002] The controlled quantity of the position servo system is the position (expressed by linear displacement or angular displacement). When the given amount of position changes arbitrarily, the main task of the system is to make the output quickly and accurately reproduce the change of the given amount. In production practice, the application field of the position follower system is very wide. For example, the automatic control of the roll reduction of the rolling mill, the positioning control and processing trajectory control of the CNC machine tool, the automatic manipulation of the rudder, the automatic tracking of the artillery position, the automatic driving of aerospace equipment, the motion control of robots, etc. [0003] With the development of mechatronics technology, the position follower system has become an indispensable equipment in the fields of mod...

AI Technical Summary

Problems solved by technology

However, when the position of this system drops, the servo motor becomes a generator due to the inertia of the entire mechanical device, which supplies power to the driver in reverse, resulting in a large increase in the bus voltage of the driver, frequent alarms, and the device stops working

[0005] At the same time, the position follower system with the servo motor as the core cannot adapt to the environment of large torque changes

Moreover, in an environment where organic solvents volatilize, this position follower system is not suitable because it will generate electric sparks
