DS Series Dry Screw Vacuum Pump Features1.Exhaust Path Is
Short, Reduce The Deposition Of Reactants.Comparing with other
types of dry vacuum pump,DENAIR screw vacuum pump has the shortest
gas path in the vacuum pump and that could reduce the contamination
of process gas. Screw rotors can play as a powder transmission
mechanism,we runs well even there has lots of contamination inside
the pump.2.The Optimal Linear Sealing, The Pump
Performance.Patented rotor profile can provide rotor excellent
sealing effects thus a larger clearance is allowable in
between.Pump rotor wesring and rotor jam by the process
contamination can be reduced by larger allowable
clearcance.3.Simple Structure, Low Fault Rate And Easy
MaintenanceScrew type vacuum is composed by a pair of screw
rotor and isolation plates are required in different between rotors
and isolation plates can also be avoided.Overhaul Hanbell dry pump
is much easier than other type of dry pump,so the erpair time is
shorter and the cost is saver.4.Microcomputer Operation, Remote
Monitoring, Considerate ProtectionMicroprocessor controller
provides lots of pump parameters for running status monitoring.Pump
can be easily operated and monitored by the operation panel.Remote
control software can help the customer monitor the pump running
status remotely.DS Vacuum Pump Speed CurveAdvantages1.Special
cooling liquid cooling, to avoid the cooling water may cause
corrosion to the hull. 2.Mobile operation interface,
convenient operation; Display and the actual work of vacuum pump
and can be selected to both languages, according to the real close
to the customer.3.Catch the power connector, safe and
convenient.4.The nitrogen gas heater, make the vacuum pump is more
suitable for CVD, PECVD and other semiconductor technique
process.5.The control signals and communication signal interface,
remote monitoring was carried out on the
vacuum. Application1.The health care industry.2.Lighting
industry.3.A variety of analytical instruments.4.Electronics,
semiconductor industry. 5.The power industry.6.Refrigeration
industry.Technical
