Introduction:

JZJLG150-3T type Roots screw vacuum unit is a vacuum suction unit composed of ZJ150G Roots pump, LG50G screw vacuum pump in series. The main features of single crystal silicon vacuum-drawing process are as follows:

Advantage:

1. The unit is mainly composed of Roots vacuum pump, screw vacuum pump, muffler and so on. It belongs to dry vacuum pump, which has no oil and gas pollution in the contact part of the system, and is easy to be centralized treated or recycled by the exhaust body.

2. The pumping performance of the unit is stable, and the influence of ambient temperature and cooling water temperature is small.

3.The buffer dust removal tank in the inlet pipe of the unit (optional) can effectively filter a large amount of dust in the gas, reduce the dust into the vacuum pump cavity, and avoid the failure caused by dust.

4.There is no friction between the Roots vacuum pump and the wet part of the screw vacuum pump, the parts of the vacuum pump are not easy to wear, the life of the pump is long, and it is insensitive to the small particle dust, so the gas containing a small amount of small particle dust can be removed.

5.High vacuum unit, big capacity in high vacuum area .

6.Compact structure, small area, small vibration, easy to install and use, the user can only connect the intake and exhaust pipes, cooling waterways and circuits.

7.The vacuum unit adopts the vertical structure and occupies a small area.

8.The ZJ150G Roots pump is driven by frequency converter, and the control system of the unit adopts PLC intelligent control. The control program can be customized according to the customer’s technological needs, which can automatically meet the requirements of different pumping speed and constant pressure of different air output of the customer’s process in different periods of time, so as to better ensure the customer’s production needs.
