Rotary Vacuum Pump in Drug Packaging

Pharmaceutical packaging machinery is a branch of general packaging machinery with high technical content and requirements. The application of rotary vane vacuum pump in pharmaceutical packaging is due to the higher health requirements of the pharmaceutical industry. The general packaging machine can not meet the requirements of the pharmaceutical industry. Rotary vane vacuum pump also has a good performance in the pharmaceutical packaging industry with its unique performance. After vacuum packaging, medicine mostly exists in a clean and sterile situation, which improves the safety and retention time of pharmaceutical products.

First, let’s get to know the concept of drug packaging. Pharmaceutical packaging refers to the general name of a processing process that uses appropriate materials or containers and packaging technology to separate (fill), seal, pack and label the semi-finished products or finished products of pharmaceutical preparations to provide quality assurance, identification of trademarks and instructions for medicines. Drug packaging itself can be understood from two aspects: from a static point of view, packaging is the packaging of drugs with materials, containers and auxiliary materials, playing its due role; from a dynamic point of view, packaging is the technical method of using materials, containers and auxiliary materials, is the process and operation. The role of pharmaceutical packaging in the field of circulation on schedule can be divided into two categories: internal packaging and external packaging. Its functions mainly include three aspects: protection function, convenient application and commodity publicity.

Rotary vane vacuum pump is mainly composed of pump body, rotor, rotary vane, end cover, spring and so on. A rotor is eccentrically installed in the cavity of the rotary vane vacuum pump. The outer circle of the rotor is tangent to the inner surface of the pump cavity (there is a small gap between them). Two rotary vanes with springs are installed in the rotor groove. When rotating, centrifugal force and spring tension keep the top of the rotor in contact with the inner wall of the pump chamber. Rotor rotation drives the blade to slide along the inner wall of the pump chamber.

SV Rotary Vane Vacuum Pump

Rotary vane vacuum pump features:

1. Fast pumping speed, small size, light weight, low noise, easy maintenance, high vacuum limit. According to the international limit, the vacuum is 6 x 10-2 Pa (i.e. 5 x 10-4 Torr, note: Torr = 133.32 Pa).

2. Reliable dust-proof device. Other rotary vane pumps can be connected into the pump chamber when sundries pass through the dust-proof device. The vacuum pump produced by our company can only flow around the outside of the dust-proof device when sundries pass through the dust-proof device. This ensures the normal operation of the pump and thoroughly solves the phenomenon that the impurities enter the pump chamber and bite to death.

3. There is a compound screw with an exhaust valve leading into the oil hole. The two-stage rotary vane pump manufactured in China for many years, the oil inlet holes are designed on the low-level exhaust valve seat inside the tank. When the oil hole is blocked, it is necessary to release the oil and remove the oil tank in order to dredge the oil hole. Vacuum pump can dredge oil holes and discharge impurities and water vapor as long as compound screw is turned out. It is fast and labor-saving, and greatly improves the efficiency of the pump.

Compared with other packaging machines, the most prominent role of rotary vane vacuum pump in drug packaging is to avoid the safety problems such as mildew and deterioration caused by the contact between drugs and oxygen, and to effectively maintain the original clean and sterile state of drugs for a long time. At present, pharmaceutical products have tended to be refined and diversified. Rotary vane vacuum pump has become a must in drug packaging industry. The equipped packaging equipment meets the rapid development needs of the pharmaceutical industry, and a large number of production lines have been transformed to bring huge market for pharmaceutical machinery enterprises.
