◎使用安全

◎Safe in use

A. Main shaft bearing safety running
1) Optimize main shaft bearing structure,assembly and dis-assembly both simply and reliable,ensure safe usage of bearing.
2) Centralized lubrication of grease. Main bearing separately supply grease to upper unit and lower unit by high pressure,downgrade of on site maintenance difficulty.
B. Liquid material safely spread within drum
Distribution method：Blade wind wheel rotative distribution
1) Relieve attrition caused by liquid disorder.
2) Remove distribution blockage and unevenly distribution made by liquid pressure wall nearby outlet.
3) Reduce the time of material stays within distributor,evenly distribution.
4) Relieve unusual vibration of equipment,protect accessories and components.
C. Residues safety
Residues removal：lever type automatically remove residues on filter bag.
In operate state,filter bag adhesive to drum interior wall；in non-operate state,filter bag deforms under the effect of connecting rod（become a 60 degree circular cone concentric with main shaft),remove residues on filter cloth and discharge by outlet.
1) Connecting rod has a simple structure and reliable function.
2) Improved separation effectiveness.
3) Effectively remove residues,protect material from cross infection.
D. Operation safety
Unique design ensure safety of on site personnel and equipment running.
1) External manual oil pump,facilitate on site personnel to operation,ensure on-duty maintenance for main shaft bearing ,reduce failure rate meanwhile promote production efficiency.
2) High pressure oil pipeline and circuit designed within shield,interfaces are laid together. Clean and tidy,ensure safety of human and equipment.
3) Adopt HMI and PLC,unattended operation,automatically monitoring and protecting.

◎维护安全

◎Safety in maintenance

一、主轴拆卸、装配安全
创新设计的上抽式主轴，配合NU系列内外圈可脱卸圆柱轴承，可方便主轴从机体分离，降低装配与拆卸难度，提高安装质量，拆装方便快捷，零件无损伤。
二、主机轴承座与轴承外圈拆卸、装配安全
创新设计的分离式轴承座套结构，改变传统的轴承外圈直接与轴承座主体安装的方式，现场拆卸方便简易，零件无损伤。
三、主轴轴承内圈拆卸、装配安全
主轴在设计时参考高压油拆卸轴承的原理，降低维护难度，实现拆装无损伤，同时延长设备使用寿命。
四、设备防护安全
设备各功能结构模块化设计并内置于对应的外防护罩壳中，既保证了维修拆卸方便，又有效地保护人机安全。
