6、动力传动机构采用变频调速，调速范围大，适应性广 

 7、设有先进的可调滤布反冲洗装置，可以根据物料的特性调整反冲洗压力，保证滤布的脱水效果，采用先进的排液系统，可适合任何工况条件下使用。（ has advanced adjustable filter cloth reverse wash device, according to the characteristics of the material can be adjusted reverse wash pressure, guarantee of the filter cloth dehydration effect, advanced drainage system, can be suitable for use any operating conditions. ）
8、操作安全可靠，采用红外安全防护和全方位的紧急安全停车装置，可实现一人多机操作，自动化程度高、操作简单方便、安全可靠。（8、safe and reliable operation, USES the infrared safety protection and comprehensive emergency safety parking device, which can realize one person's much machine operation, a high degree of automation, easy to operate, safe and reliable. ）

五、结构特点 （Five:the structure characteristics）

 1、环形胶带采用伸缩性能良好的波浪形裙边与平胶带粘接结构，造价低、寿命长。且裙边可更换。（1、 the annular tape wavy can good scalability skirt hem and flat rubber adhesive structure, low cost, long service life. And skirt hem replaceable.0

2、真空箱和胶带间设有环形摩擦带并以水密封、润滑、冷却，真空密封可靠，环形摩擦带摩擦阻力小、使用寿命长且更换方便、快捷。（2、 the chamber and duct tape with friction between the ring with and to a water seal, lubrication and cooling, vacuum sealing is reliable, the ring with friction friction resistance, long service life and easy to change, quickly.）

 3、胶带采用气垫式或者水膜支承，胶带漂浮在气垫或者水膜上，减少了运行阻力，有利于延长胶带的使用寿命。（3、rubber belt support the use of air cushion or water film, rubber belt, or floating in the water film on the air, reducing the running resistance, help to extend the life of rubber belt.）

 4、胶带支承滤布、承受真空吸力及传递功率和承受重量，并在真空箱上滑动，滤布不与真空箱接触，滤布的使用寿命较长。(4,Rebber belt supporting filter cloth, bear vacuum suction and transfer power and bear the weight, and in the chamber sliding, filter cloth is not with chamber contact, filtration cloth service life is long.)

 5、实现了连续运行、连续过滤、洗涤等作业，可以维持稳定的真空度，降低滤饼的含水量且有利于稳定操作工艺条件。（5、And realize the continuous operation, continuous filtration, washing and other assignments, can maintain the stable vacuum degree, lower filter cake and the water content of the stability for the operation process conditions.）

6、易损件少，故障率低，长期连续稳定运行可靠，处理量大。（6、Less easily broken parts, running low failure rate, long-term continuous stable, safe, reliable, large production capacity.）
