- in the selection of suction machines in vacuum pump Union star packaging machinery

In the vacuum pump market, suction machines in the application of the vacuum pump is particularly wide, wet weather in the south, blister, after heating of materials can have certain moisture evaporation, which requires the matching of the vacuum pump has functions in addition to water: 1. Suction machines in choosing vacuum pump needs to select the vacuum pump according to the specific process, mainly in the following two main parameters for reference: 2. Vacuum degree: the so-called vacuum degree is a kind of representation, the degree of thin air with palmer Pa, millibars Mba, usually said mmHg mmHg etc. 3. In blister after molding, products, product bubble is mostly to vacuum can not meet the requirements, and result in the phenomenon of products appear defects. Relative to the products of deep groove, vacuum requirement is high. 4. Traffic: refers to the unit time through the closed pipes or vacuum pump suction as well as effective cross-sectional body fluid volume, commonly used M3 / H, L/S, 5 L/Min. Vacuum flow is an important measure of suction marks, we should pay attention to when choosing a vacuum pump, the specifications of the products, to calculate the thickness of him for an hour, or a minute, need surking air how much, so to determine how much flow of the vacuum pump.
