DESCRIPTION
Roots Rotary Piston Pump System is made up with the Roots Vacuum Pump and Rotary Piston Vacuum Pump in series connection. Rotary Piston Vacuum Pump is used as the pre-vacuum pump and the backing vacuum pump of the Roots Vacuum Pump, while the Roots Vacuum Pump is the main vacuum pump. The selection of displacement ratio, between the Roots Vacuum Pump and the Rotary Piston Vacuum Pump, is mainly referred to the vacuum value of the vacuum system under long term running; when working in low vacuum, it is advised to select small displacement ratio(2:1 to 4:1); If working in medium or high vacuum, the bigger displacement ratio(4:1to10:1)should be preferred.





ADVANTAGE
1.High vacuum, high exhausting efficiency in medium or high vacuum, wide working range, obvious energy-saving results.
2. Integrated rack, compact structure, small required space.
3. High automation, simple operation, easy maintenance, safe, reliable and durable running.
4. To customize a special pump system as per the specific needs of the end user.

Welded Plate Heat Exchanger belongs to Recuperative Heat Exchanger, and is fully welded between every two plates to form channels through which the fluids with different temperature can flow and exchange heat. The high temperature fluid transfers heat to the low temperature fluid through the plates, thereby realize heat exchanging. The flow velocity of each fluid can be controlled by plates distance, so as to meet the working condition perfectly. In addition, there is also the semi-welded type plate heat exchange.
Welded Plate Heat Exchanger is mainly for vapor condensing and liquid to liquid heat exchanging, to meet with various requirements from industries like power sector, petrochemical, petroleum coking, pharmacy, metallurgy, refrigeration, paper processing etc. Optimal arrangement of various channels also make sure of high heat transfer efficiency and minimal pressure loss. Besides, its frame is detachable, and therefore it is convenient to have either mechanical cleaning or chemical cleaning as per actual situations.
