工作原理

         液/固混合流體通過進料管經(jīng)布料盤加速均勻分布于離心機轉(zhuǎn)鼓內(nèi)，在離心力場作用下，通過濾片截留固相，濾出液相。持續(xù)進料，直至料滿，停止進料，如工藝需要時則對濾餅進行洗滌、提純，同時將洗滌液濾出。進一步脫液，直至達到分離要求。降至低速，刮刀將大部分濾餅刮下，抻袋裝置將殘余濾餅卸出，完成一次工作循環(huán)。

         LGZ系列除了沒有抻袋功能，其它過程與上述同樣。

Operating principle

The mixture of solid and liquid is distributed uniformly&quickly in centrifuge drum by feeding tube and distributing evenly through the distributing disk. acting on the centrifugal position. Liquid-solid mixed fluid intercept the solid phase through the fitter to filter out the liquid phase. Centrifuge continues to feed until full. Then stop. Solid cake is rinsed and purified when the process requires. And the rinsing liquid is filtered out meanwhile.  Centrifuge further filter until the separation requirements are met.

控制過程

         離心機運行由PLC控制，系統(tǒng)按預設(shè)運行程序自動運行。不同的機型有相應(yīng)的運行參數(shù)或調(diào)整范圍，對特定的工況在調(diào)試和后續(xù)的

運行中設(shè)定合適的運行參數(shù)，以滿足分離要求。控制系統(tǒng)對實際運行過程中的過載進行自動修復或保護。

         自動控制系統(tǒng)對離心機主機、液壓系統(tǒng)、氣動系統(tǒng)、氮氣保護系統(tǒng)、閥門以及與離心機相關(guān)的泵、閥、物料輸送系統(tǒng)等進行控制。

Control Process

The operation of centrifuge is controlled by PLC. The system runs automatically according to the preset program. Different centrifuges have corresponding operating parameters or range of adjustment.

In order to meet the requirements of separation. appropriate operation parameters are set for specific conditions

in debugging and subsequent operation. The control system can automatically repair or protect the overload in the actual operation.

Automatic control system controls centrifuge mainframe, hydraulic system, pneumatic system, N2 protection system,and pump, valve, material conveying system related with centrifuge, etc.
