Electric control device of double-system helium recycling equipment

Abstract

The invention relates to an electric control device of double-system helium recycling equipment. An intensive display operation unit is used for inputting an operation parameter to a PLC (Programmable Logic Controller) module assembly; the PLC module assembly is used for calculating the operation parameter to output a control signal to a control executing circuit; the control executing circuit controls helium compressor executing equipment, cooling device executing equipment, and drying and purifying device equipment to work; a helium compressor detection element, a cooling device detection element and a drying and purifying device detection element respectively detect the operation parameters of a helium compressor, a cooling device and a drying and purifying device and convey the operation parameters to the PLC module assembly to combine with the operation parameters to output a real-time control signal to the control executing circuit. The device is convenient to operate and is safe and reliable; and the use state of the helium recycling equipment can be monitored and controlled in real time so as to be suitable for various environments.

Description

technical field [0001] The invention relates to the field of helium gas recovery, in particular to an electrical control device for dual-system helium gas recovery equipment. Background technique [0002] Helium is a rare resource. my country is a country with poor helium resources. Helium is expensive. At present, a large amount of helium needs to be imported from abroad. The recovery and purification of helium is not only for saving resources, but also very cost-effective from an economic point of view. [0003] Helium recovery equipment is used to realize the recovery and purification of helium. It is mainly divided into three working units: cooling device, helium compressor, and drying and purification device. Because the three working units are purchased independently, the electrical control of helium recovery equipment in the past is also It is divided into electrical control of cooling device, electrical control of helium compressor, and electrical control of drying a...
