Rotary vane vacuum pumps applied in pharmaceutical packaging _

pharmaceutical packaging machinery is a branch of general packaging machinery, with high technical content and requirements. Rotary vane vacuum pump application in drug packaging is due to the high health pharmaceutical industry requirements. General packaging machine can meet the requirements of the pharmaceutical industry. Rotary vane vacuum pump with its unique performance in the pharmaceutical packaging industry also has a good performance. After vacuum packaging, most drugs in clean condition, improved the security of the drug and retention time. On the basis of the content will introduce the characteristics of the rotary vane vacuum pump.

first of all, let's look at the concept of pharmaceutical packaging.

pharmaceutical packaging refers to using the appropriate materials or containers, packaging technology using separation ( Fill in) , seal, loading, label drugs such as semi-finished or finished products, to provide quality assurance, brand identification and specification. Drugs. Handle general terms. Pharmaceutical packaging itself can be from two aspects to understand: from the static point of view, packaging is the use of materials, packaging containers and auxiliary materials to drugs and according to its functions; From the dynamic point of view, the packing is made of materials. Container, auxiliary equipment and technology method is the process and operation process. Role in the field of pharmaceutical packaging in circulation can be divided into two categories: the inner packing and outer packing. There are three main functions, that is, protection function, convenient application and product promotion.

rotary vane vacuum pump is mainly composed of pump body, rotor, vane, plate, springs, etc. The rotor eccentricity to install in the cavity of rotary-vane vacuum water pump, the inner surface of the outer periphery of the rotor and the pump cavity tangent ( There is little gap between) And decorated with two rotor blades in the rotor slot with spring. When rotating, the top of the rotary vane by centrifugal force and the spring tension to keep contact with the pump chamber wall, and the rotation of the rotor drives the rotary vane sliding along the wall.

1. Pumping speed is fast, small volume, light weight, low noise, easy maintenance, high ultimate vacuum. According to the limit and vacuum degree is 6 x 10 - 2Pa（ 5 x 10 - namely 4 Torr, note: Torr = 133. 32Pa） 。

2。 Have reliable dustproof device. When debris through dust device, other rotary vane water pump can be connected to the pump room. Our company produces the vacuum pump through dust control device, can only flow on the outside of the dust control device. It ensure the normal operation of pump and completely solved the problem of the debris into the pump chamber.

3。 There is a belt exhaust valve and the inlet of the composite screw. In China for many years the production of two stage rotary vane pump, the oil hole on the tank low exhaust valve seat design. When the oil hole jam, should remove oil discharge and the fuel tank to remove oil hole. As long as unscrewing composite screw vacuum pump, it can remove oil hole side by side out of the debris and water vapor. That is to say, it's fast and effort, which greatly improve the efficiency of the pump.

compared with other packing machine, rotary vane vacuum pump application in the pharmaceutical packaging is one of the most prominent features. It avoids the drugs caused by contact with oxygen mold and metamorphic security issues, such as to be able to effectively keep the drug for a long time of the cleaning and disinfection. In the current state, the pharmaceutical products become more delicate and diversification. Rotary vane vacuum pump has become an indispensable packaging equipment, pharmaceutical packaging industry meets the requirements of the rapid development of the pharmaceutical industry. A large number of production line transition has brought the huge market.
