Screw vacuum pump for vacuum recovery

Screw vacuum pump and other equipment in the system is directly related to the function of screw vacuum pump can be useful to play the question.

Material steam was condensed into liquid in condenser, but under the condition of vacuum, gas molecule speed accelerate, gas density decreases, and the material of the condensation temperature is reduced, the total heat transfer coefficient of condenser exponentially decreases, and thus materials in the vacuum condensate (a condensation) is often not very abundant, especially the low boiling point solvent. One part of the uncondensed gas is liquefied in the vacuum pump with the change of pressure, and the other part is condensed in the exhaust side condenser at normal pressure (secondary condensation).

Because the screw vacuum pump has no vacuum medium (vacuum pump oil, water, etc.), the gas through the screw vacuum pump is not polluted by the vacuum medium, so the solvent is clean. So the condensing part of the vacuum is converted to condensing under normal pressure, which greatly improves the recovery rate of solvent materials, especially favorable for the materials difficult to condense under vacuum. After the process equipment, the exhaust emissions have no organic waste gas. In addition, the noise is greatly reduced after the pump empters the gas through the shell side of the condenser.

EVP began to introduce lean production concepts and tools, and began to fully implement. The tool has now been expanded to non-production areas. This includes 5S activities, JIT, vendor kanban, relayout, process reengineering, production unit, VSM, rapid mold change, and more. All of these activities revolve around the goal of reducing and eliminating waste, meeting customer requirements, and responding quickly.

We sincerely welcome new and old customers to visit our factory and negotiate with us. We are willing to cooperate with you, devote ourselves to the development and application of vacuum technology, and establish long-term technical cooperation and business contacts. We will abide by the principle of “quality first, reputation first, service first” to provide you with quality products and good after-sales service.
