Oil Less Rotary Vane Type Vacuum Pump in Plastic Industry
The specific application in oil less rotary vane type vacuum pump and central centralized vacuum system: vacuum forming.
oil less rotary vane type vacuum pump in blister industry is mainly used in blister forming process. Through the attraction of vacuum pump, raw materials are close to grinding wheel and heated to soften products. According to the material thickness classification, there are mainly two kinds of thick materials and thin materials.
Selection method of vacuum pump in blister industry:
In the selection of vacuum pump in blister industry, the following two parameters are selected.
Vacuum degree: vacuum degree is a kind of expression of air rarefaction, which is usually expressed in units of millibar, milli amalgam mmHg, etc.
After the foam product is formed, the bubbles of the product should not be really empty, so there are many phenomena of product defects. The requirements of vacuum degree vary with the size and other factors.
Flow: refers to the amount of fluid pumped out by vacuum pump in closed pipeline or effective broken body per unit time, usually expressed by m3 / h, L / s and L / min.
Precautions for the use of oil less rotary vane type vacuum pump in blister industry:
Many users ignore its maintenance, vacuum pump and other mechanical equipment need routine maintenance, in order to better play its performance, maintenance must pay attention to several issues.
1. Regularly observe the color of vacuum pump oil, and maintain it when the color is brown, black, milky white and condensed.
2. When the vacuum pump has abnormal noise, stop the pump and check the cause of the noise.
3. The oil mist separator with built-in vacuum pump needs to be replaced regularly, generally every 2000 hours, to prevent the oil mist separator failure and smoke from the pump exhaust port.
Advantages of monopole oil less rotary vane type vacuum pump:
1. Vacuum degree: high vacuum degree of oil rotary vane vacuum pump.
2. Service life: epoxy resin glass plate is used inside the oil rotary vane vacuum pump, lubricated with lubricating oil, with long service life.
3. Noise: the running noise of oil type rotary vane vacuum pump is small.
4. Maintenance of oil less rotary vane type vacuum pump: the maintenance of oil rotary vane vacuum pump requires replacement of lubricating oil exhaust filter.
