Pneumatic press, is a compressed air as power source, simple structure, easy operation and high working efficiency. No hydraulic system standby produced noise, power consumption to reduce the production cost can be saved.
Pneumatic press has a lot of kinds, respectively is PRNA, PRNB, PRNC, PRND series, oil pressure supercharge press machine has PRAC, PRAD series. Both of them exist some differences, reflected effect is also different. So, how to choose appropriate pneumatic press?
Pneumatic press to PRNA, PRNB, PRNC, PRND series maximum infliction pressure 1300T specifications as an example, the connection is respectively 250 mm, 300 mm, 300 mm, 280 mm. Cylinder size is 160 * 100 mm, but, because the maximum pressure value is different, cylinder specifications are different. Formulate adjustable stroke of cylinder is 50 mm, including different pressure value pneumatic press PRN series. Area of working bench respectively: 250 * 250 mm, 250 * 245 mm, 310 * 270 mm, 350 * 240 mm.
Oil pressure supercharge press machine PRAC, PRAD series of the maximum infliction pressure 10T specification as an example, area of working bench respectively 360 * 260 mm, 350 * 240 mm. Per minute roundtrip time (route 100 mm) respectively about for 20 / min, 25 / minutes. But, because the maximum infliction pressure value is different, there are a lot of specifications have differences.
To ensure that the pneumatic press can exert different pressure value, more and more manufacturers pneumatic press machine according to the maximum pressure is divided into different series, in order to satisfy various requirements. Because maximum exert pressure is different, pneumatic press working pressure, theory pressure, weight will be different. So, when choosing pneumatic press, first should realize what kind of effect you want to achieve, and then think about the price and after-sales service, but if the machine is bought very cheap, maintenance cost is high, it will have to consider.
