Vacuum system for PET sheet extrusion

For sheet extrusion / centralized water supply, the vacuum degree of sheet extruder is generally required to be above – 100KPA, which can meet the use requirements. On this basis, the higher the vacuum degree, the better the sheet quality. If the vacuum degree is not reached, it will cause problems such as low transparency and brittle sheet.

Roots water ring vacuum system of advantages

1. The three leaf roots vacuum pump is adopted, which has the advantage of high efficiency sealing, can prevent the volatile gas from entering the oil tank to cause oil emulsification, the high vacuum degree is stable, the production efficiency is increased by more than 10%, and it is safer and more reliable without alcohol cleaning; The vacuum degree can be as high as – 101kpa under the action of two-stage roots vacuum pump.

2. Water ring vacuum pump is adopted, which has the advantage of low noise (less than 70 points); The service life is up to 30 years; Except for mechanical seal and exhaust valve plate, there are no vulnerable and consumable parts; The motor is directly connected with the pump head, without bracket and coupling, so the operation is more stable and the efficiency is higher.

Roots water ring vacuum system and PET sheet vacuum machine are equipped with high-quality vacuum pumps. The vacuum system group operates stably and has high vacuum degree, which greatly improves the quality of pet sheets and solves the problems of low transparency and brittleness of pet sheets worried by customers.

This is a roots water ring vacuum system, commonly known as the pet vacuum system, which can be used for PET sheet extrusion. It uses a three leaf roots pump, with good sealing performance to prevent oil emulsification, no alcohol cleaning, vacuum degree of – 101kpa, and noise as low as 70 dB. This vacuum system can effectively solve the problems of low transparency and brittle pet sheets. Are you sure you can’t come?
