Abstract

The invention relates to a movable clean compressed gas preparation device, in particular to a volumetric gas compressor with large gas output, small volume, low humidity of the output gas, no need for an external cooling medium source, and can be moved and adapted to field operations . The present invention includes at least one piston compression cylinder (7) and one diaphragm compression cylinder (8), and the gas purification and drying module (23) is connected between the two cylinders (7, 8); it also includes a built-in circulating cooling device, which is stored by a cooling medium The box (3), the pump (5), the gas compressor cooling pipeline, and the radiator (9) are connected through pipelines and pipeline components in sequence. The advantage of the present invention is that by combining the two compression methods, piston compression and diaphragm compression, and connecting the gas purification and drying module between them, high-clean medium and high-pressure gas can be produced, and the cooling device is built in, without the need for Separate external cooling medium sources such as cooling water, compact structure, easy to move at any time, low requirements on working environment conditions, especially suitable for field operations.

Description

technical field

[0001] The invention relates to a movable clean compressed gas preparation device, in particular to a volumetric gas compressor with large gas output, small volume, low humidity of the output gas, no need for an external cooling medium source, and can be moved and adapted to field operations . Background technique

[0002] Dry and clean medium and high pressure gases are often used to clean devices sensitive to humidity, or for special experiments. The diaphragm of the diaphragm compressor is clamped between the cover plate and the body, and the diaphragm is isolated from other spaces except the intake and exhaust passages. Therefore, this kind of machine will not leak during the process of processing gas, will not be polluted by lubricating oil, etc., and the gas produced is relatively clean. However, due to the limitation of the deformation of the metal diaphragm and the inertia of the liquid, the size of the machine cannot be too large, the speed is low,...
