An automatic gas pressurization device

Abstract

The invention relates to an automatic gas pressurizing device which comprises a device cabinet. A control unit, a pipe unit and a power source are arranged in the device cabinet. The control unit comprises an upper computer and a PLC, and the upper computer is connected with the PLC through a communication cable. The pipe unit comprises a driving gas input pipe, a gas input pipe, a booster pump and a high-pressure gas output pipe, a second branch is connected between the output end of a driving gas input source and a filter reducing valve, digital ports of the PLC are connected with a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve respectively, and analog quantity output ports of the PLC are connected with a first electrical proportional valve and a second electrical proportional valve respectively. The automatic gas pressurizing device has the advantages that the gas driven booster pump is adopted, the pressurizing speed is guaranteed, the working time of the booster pump is guaranteed, and the service life of the booster pump is long; mechanical-electrical integration design is adopted, and the automatic gas pressurizing device is small in size, light in weight and convenient to move; the driving gas electrical proportional valves and the gas control reducing valve are allocated, the driving gas output pressure and the driving gas pressurizing speed can be controlled, and therefore the gas driven booster pump is controlled to slowly and stably carry out pressurizing to enable the test pressure to be achieved.

Description

technical field [0001] The invention relates to an automatic gas pressurization device. Background technique [0002] The reactor belongs to the category of pressure vessel and is a special equipment that needs to accept the safety supervision of government departments. It is an industrial product comprehensively developed in a number of new materials, new technologies, and new processes. At the same time, it is a catalyst for many new industries and is widely used. The performance requirements of high-pressure reactors in all aspects far exceed those of conventional industrial application reactors. [0003] Most of the existing reactors are filled with electric-driven membrane presses. There are problems and shortcomings in the filling of electric-driven membrane presses: single function, complex operation, large volume and weight, low degree of automation, and only manual filling; Directly driven by the motor, the cycle speed is not adjustable, the flow rate is not varia...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing reactors are filled with electric-driven membrane presses. There are problems and shortcomings in the filling of electric-driven membrane presses: single function, complex operation, large volume and weight, low degree of automation, and only manual filling; Directly driven by the motor, the cycle speed is not adjustable, the flow rate is not variable, and it cannot be used for multiple pressure filling; the inlet pressure range is narrow, and when the inlet pressure is high, it generally needs a decompression device to decompress, which is a waste of energy. It belongs to blind filling and is safe. The coefficient is not high; it needs to be equipped with additional power and cooling equipment, the cost is high, and it is easy to cause pollution

Reasons for existence: limitations of electric membrane press technology; relatively little domestic investment and research in this field, and insufficient attention to multifunctional, automated systems, and environmentally friendly products
