DS系列干式螺杆真空泵特点：

排气路径短，减少反应物沉积/Exhaust Path Is Short, Reduce The Deposition Of Reactants.

●干式螺旋真空泵相较于其他形式的真空泵，因气体于泵浦内的传输路径更短，不易产生反应物沉积的现象/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 tran***ission mechani***,we runs well even there has lots of contamination inside the pump.

线形密封性佳，泵浦性能更优/The Optimal Linear Sealing, The Pump Performance

●专利转子密封线形，转子密封性佳，转子能以较大的啮合间隙达到更快的抽气效果。由于啮合间隙较大，泵浦较不易因制程气体沉积而卡死，转子也较不易因麿耗而需更换/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.

结构简单，故障率低，维修容易/Simple Structure, Low Fault Rate And Easy Maintenance

●螺旋式真空泵因需利用一对转子互相啮合达到密封效果，结构上不像其他形式的真空泵需要有中 间隔板的设计，降低转子与隔板沉积卡死的风险。且因其结构单纯，拆解维修也较容易，因此能 缩短维修时程，降低维修费用/Screw 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 ***oided.Overhaul Hanbell dry pump is much easier than other type of dry pump,so the erpair time is shorter and the cost is s***er.

微电脑操作，远端监控，保护周全/Microcomputer Operation, Remote Monitoring, C***iderate Protection

●微电脑操控器提供真空泵浦简单的操作方式并能显示泵浦完整的运转状态，方便使用者对泵浦 应用状况进行调整，在泵浦产生问题前进行预防***。远端监控系统能提供使用者方便的监控工具，使用者不需到现场即能查询泵浦之运转状况/Microprocessor controller provides lots of pump parameters for running status monitoring.Pump can be easily operated and monitored by the operation mote control software can help the customer monitor the pump running status remotely.

性能优势：

●专用冷却液冷却，避免了冷却水可能对壳体造成腐蚀/Special cooling liquid cooling, to ***oid the cooling water may cause corrosion to the hull.

●移动式操作界面，方便操作；显示真空泵实际工作状况，并可选中英两种文字显示，切实贴近客户/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.

●军规电源接头，安全方便/Catch the power connector, safe and convenient.

●氮气加热器，使真空泵更适应于CVD、PECVD等半导体制程/The nitrogen gas heater, make the vacuum pump is more suitable for CVD, PECVD and other semiconductor technique process.

●控制讯号及通讯信号接口，可对真空泵进行远端监控/The control signals and communication signal interface, remote monitoring was carried out on the vacuum pump.
