Brief introduction

   Yili series Roots water jet vacuum unit is theRoots pump (also called as mechanical booster pump) as the main pump (including the middle pump, which has two types: anti-corrosive and corrosive,the anti-corrosive type is to reach good non-corrosive effect after thepainting treatment), water jet pump is consist of fore -pump. The unit iswidely applied in the technology process like the vacuum dry, distillation andconcentration etc, and it has been widely applied in the metallurgy, petroleumchemical industry, food and electronic industry etc. It can meet the customers’practical requirement, and design the multi-stage unit so as to improve the suctionof the unit and vacuum degree.

The characteristics

   Take the complete plastic horizontal axis of thewater jet vacuum unit as the fore pump, which can suction the corrosive gas. Theextreme vacuum of the first Roots pump can reach 150 Pa, and the extreme vacuumof the second Roots pump can reach 25Pa. PS. Some anti-corrosion Roots pump canbe selected as well.

The model and technique parameters

Note: Measurement condition: gas temperature 20, the atmosphericpressure 1013.25hpa( amount to 760mmHg, therelative humidity 70%, the water temperature 15.

the air-suction speedallowance±10%

③The value of the vacuumdegree in the meter means the pressure less than the standard atmosphericpressure.

(1mmHg=1Torr(托)=133.3Pa(帕)0.1Mpa=750mmHg)
