工作原理

  Operating principle

        TZ系列(流體增壓)壓力抽吸排液臥式螺旋自動卸料沉降離心機分離技術:應用TF系列流體增壓防爆臥式螺旋自動卸料沉降離心機分離技術、改變上清液排卸方式, 分離后上清液通過自吸泵機械結構從轉鼓內腔中管道排出。避免流體與空氣接觸,適用于有毒性、易揮發性、易燃易爆性、防二次污染等場合。同時有效防止特殊性質物料的上清液與空氣接觸,產生泡沫造成排液通道受阻。

 

 

 

 

 
Separation techniques of(LW)TZ series(fluid pressurization)pressure suction drain horizontal spiral automatic scrolling centrifuge:applying TF series fluid pressurization and explosion-proof horizontal spiral automatic scrolling centrifuge separation technique,changes discharge way of supernatant. After separation,supernatant is discharged from pipeline of the bowl cavity through mechanical structure of self-priming pump.Keep fluid from contacting with air,which is suitable for toxic,volatile,flammable and explosive,anti-secondary-pollution occasions.Moreover,supernatant of special materials wouldn't contact with air and produce foam,to block liquid discharge passage.

Main technical features

1、工業化設計
整機設計遵循并綜合了工業設計理念,突出了主體結構的穩定性、主機功能性及整機安全性,并有效吸收了設備運行時的動載荷剪切力。
 
 
1. Industrial design
Whole machine set design follows concept of advanced industrial design,ensures stability,functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.
2、有效規避雙轉子高速轉動共振區現象
在設計轉速范圍內,整機運轉時無明顯一階、二階共振區現象,軸承座部位全振動烈度控制在2mm/s~4 mm/s之間。避免了高頻振動與拍振所造成的設備各零部件的額外疲勞損傷。
 
 
 
 
2. Effectively ease resonance during rotating of bi-rotor
When centrifuge works,there is no obvious first-order and two-order resonance regions within  designed speed range;meanwhile,whole vibration intensity of bearing seat is definited within 2mm/s~4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.
3、徹底消除液環失速現象
徹底消除了整機(特別LW530以上大機型)在重負荷開機或停機過程中液環失速現象,從而避免了因液環失速所造成的整機跳動或劇烈抖動對設備主軸承及螺旋軸承、回轉體零部件額外的撞擊疲勞損傷。
 
 
 
 
3. Thoroughly eliminate phenomenon of liquid ring stalling 
Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW530 and even larger models.It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately,our engineers have solved this problem thoroughly.
4、零部件原坯料采用離心鑄造與鍛造工藝

7、可互換性
同型號的主機旋轉體及所有部件,在整機互換性結構設計與關鍵位置加工工藝及精度的保障下,均具有互換性,更加易于維護,同時也大大提高了設備的可靠性和安全性。
 
 
7. Inter-changeability
Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain,but also greatly improve the reliability and safety of equipment.
8、軸承拆卸簡易、安全
軸承與工件配合面在拆卸時被高壓注入的一層油膜分離,從根本上消除它們之間的摩擦,將拆卸時所需的拉力減小90%,降低了拆卸軸承時高精度零部件的損壞風險。
 
 
 
 
8. Simplely and safely in bearing disassemblement  
One layer of oil film is injected into contact surfaces between bearing and work-piece by high-pressure,during disassemblement bearing from the machine,which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.
9、主軸承潤滑系統

    b.Optional automatic grease system fills grease on main bearing at designed hours and quantity.
10、主軸承BH保護裝置
主軸承兩端設計有保護軸承,正常情況下保護軸承不工作(保護軸承內圈與主軸之間預留一定軸向間隙)。當主軸承在一些不可預期的極限工況中出現突發損傷、主機旋轉圓心偏移產生的跳動幅度達到保護軸承內圈與主軸預留的軸向間隙值時,保護軸承開始工作,同時主機自動控制系統檢測到軸承位振動值發生突變,設備的緊急停機程序被觸發,在保護軸承的作用下平穩停機,保障設備主體部件不受損壞,保證生產安全。
 
 
 
 
 
 
10. Main bearing BH device(patent design)
There are two spare safe bearings at either end of main bearing.When machine works well,they keep certain clearance from bearing inside track to chief axis.When unexpected condition occurs,main bearing got damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance,safe bearings begin to work as main bearing.Meanwhile,computer automatic control system would get a feedback of abnormal vibration value on bearing position immediately,then activates emergency shutdown and goes a smooth shutdown.This system protects machine free from damaging and ensure production safety.
