随着国家对环境保护的重视，卧式离心机技术在污泥处理系统中的应用得到了大力推广。离心式污泥处理具有污泥回收率高、运行可靠等优点，但也存在能耗高、噪声大等缺点。将变频技术应用于离心机系统，可在节能减排、稳定运行方面取得显著效果。

With the national attention to environmental protection, the application of horizontal centrifuge technology in sludge treatment system has been vigorously promoted.
Centrifugal sludge treatment has the advantages of high sludge recovery and reliable operation, but it also has the disadvantages of high energy consumption and high noise. The application of frequency conversion technology in centrifuge system can achieve remarkable results in energy saving, emission reduction and stable operation.

  1 、离心机工作原理 How the centrifuge works

污泥处理离心脱水机主要由鼓，螺旋体，差，主副电动机和其它设备。当给药到滚筒后的水，通过在高速旋转产生的离心力的鼓，所述固体颗粒的大部分沉积在滚筒的内壁，并且所述滚筒相对于所述螺旋体移动将不断沉积上的排渣口的内壁的固体颗粒，通过液体流出开口调节板鼓上清层分离后的滚筒挤压。

Sludge treatment centrifugal dehydrator is mainly composed of drum, helix, differential, main and auxiliary motors and other equipment. After dosing to drum water, through the high speed centrifugal force produced by the rotation of the drum, described most deposition of solid particles in the lining of the rollers, and described the helix roller relative to the stated mobile will continue to the discharge port on the deposition of the lining of the solid particles, through the liquid flow openings on regulating pan-ku roller extrusion of the separated layer.

  2. 双变频共直流电压母线进行系统 Dual frequency conversion common DC voltage bus system

  螺旋和鼓之间的相对运动 - 经由差动转速差达到，它的大小是由辅助电机的控制。差动鼓外壳和被耦合，所述输出轴与所述螺旋体，所述输入轴与辅助电机。主驱动马达同时驱动差速器壳体的旋转而旋转的滚筒中，副马达控制差分输入轴通过联接又耦合

The relative motion between the screw and the drum - achieved by differential speed difference, the size of which is controlled by the auxiliary motor. The differential drum housing is coupled to the output shaft and the helix, and the input shaft and the auxiliary motor. The main drive motor simultaneously drives the rotation of the differential housing and in the rotating drum, the auxiliary motor controls the differential input shaft through coupling and coupling.

  卧式离心机转速速度快，螺旋体速度慢，那么转鼓有带着螺旋体转动的作用力，螺旋体带着副电机转。这样就导致副电机可以接到智能电网系统运行时，其轴上受到影响主机进行驱动转矩，使转子沿同步提高转速不同方向不断旋转。此时，副机从轴上输入机械设计功率转化成电功率返回电网，处于社会回馈制动再生能源发电技术状态。

Horizontal centrifuge speed is fast, the helix speed is slow, so the drum has a helix rotation force, the helix with a deputy motor. In this way, when the secondary motor is connected to the smart grid system, the affected host on its shaft drives the torque, so that the rotor rotates continuously in different directions along the synchronous increase of speed. At this point, the auxiliary engine input mechanical design power from the shaft into electrical power back to the grid, in the social feedback braking renewable energy power generation technology state.
