the scientific 26 mm co-rotating twin screw extruders is made with a complete modular build up of the clam shell barrel, where each barrel section have a length of 4 d or 104 mm. two standard lengths are available with 32 and 40 l/d and with drive powers of 7.5 respectively 11 kw. the modular clam shell barrel is, from january 2003, supplied as high temperature versions and equipped with exchangeable barrel lining in-serts for optimum economy and ease of replacement. these standard in-serts are made from a very high grade acid resistant tool steel which is through hardened to over 60 rc and which can withstand high processing temperatures of up to 400 °c.

26毫米實驗室同向雙螺桿擠出機完全由模塊化的蚌殼式機筒組成，機筒的每個部分都有4倍直徑或104毫米長。有兩種標準長度可選：32和40倍l/d，同時驅(qū)動馬達為7.5kw和11kw可選。模塊式的蚌殼式機筒為高溫型號，而且內(nèi)襯為可更換插入式模塊，易于更換并且非常經(jīng)濟。這些標準插入模塊由硬化處理的高等級工具鋼制成，硬度超過rc60并且可承受高400 °c的處理溫度。

the screws are built up from individual single elements mounted on hexagonal hardened shafts. each individual kneading elements is supplied in many angles to enable optimum variations in screw configurations. the screw components are made from high grade tool steel which is through hardened but made with a slightly softer hardness than the barrel linings to ensure optimum life time for both elements and barrel in-serts.

螺桿由安裝在六角形硬化軸上的獨立的單元構(gòu)成，每個單元由多個角度組合來獲得*優(yōu)的螺桿配置。螺桿組件由高等級工具鋼制成并硬化，但其硬度稍低于機筒內(nèi)襯從而確保螺桿單元和機筒內(nèi)襯的*優(yōu)生命周期。

the whole clam shell barrel assembly is split in the center and can be easily swung open after loosening the barrel bolts. this gives easy access to the screws for cleaning or changing of screw elements and/or barrel in-serts as well as to observe the melt and compounding characteristics of the polymer being processed. the top half of the barrel is balanced so that very little force is needed to open it up and with this the hazard of accidental heavy closing is eliminated.

整個蚌殼式機筒組件由中間分開，旋松緊固螺栓后可以輕易地向兩側(cè)打開，這樣可以輕易地清潔料筒或更換螺桿組件/機筒內(nèi)襯模塊，當然也可觀察被加工聚合物的溶解和共混特性。機筒上部兩側(cè)的對旋轉(zhuǎn)軸保持水平，這樣用很小的力量就可以打開機筒并且避免因失誤關(guān)閉機筒的危險。

each barrel zone is equipped with both water cooling and electric cartridge heating. this allows for complete process control at each zone of the barrel and the water cooling coupled with the high wattage heating enables fast temperature changes of each zone when changing processing conditions from one compound to another. the water cooling is done from fine channels inside each barrel module and regulated with individual solenoid valves from its designated temperature controller.

每個機筒區(qū)域都同時配備了水冷和電加熱組件，這就允許對機筒的每個區(qū)域進行完全的控制。當從一個產(chǎn)品切換到另一個共混產(chǎn)品時，水冷裝置和大功率加熱結(jié)合的方式可保證每個區(qū)域的快速溫度改變。水冷是通過每個機筒模塊內(nèi)的細通道實現(xiàn)的并由溫度控制器控制的獨立螺旋閥調(diào)節(jié)。

the extruders are also, as standard, equipped with a 4 holes strand die mounted on a hinged support and connected to the barrel with a c-clamp. the barrel end part is also equipped with an easy removable breaker plate which enables production either with or without screen packs. the strand die swings aside simply by loosening the c-clamp to facilitate easy cleaning and also to enable connection of other down stream equipment to the twin screw extruder.

擠出機配有安裝在帶鉸鏈法蘭上的4孔線狀模頭，料筒末端帶有易移開的斷路盤可確保需要或不要濾網(wǎng)狀態(tài)的迅速切換。線模頭可通過松開c型夾具輕易地打開，由此可以方便清潔同時并利于客戶聯(lián)接其他下游設(shè)備。

the extruders can optionally be equipped with one or more twin screw side feeders which are connected to the side of the barrel module. a special barrel module with opening as well as plug for side feeder is needed for this option and the extruder can be supplied with several plugged side feeder modules for optimum flexibility of side feeder location. the side feeder have a infinite variable speed drive with 26 mm diameter twin screws built up from same elements as the main screws, and with an l/d ratio of 10. the barrel of the side feeder is equipped with water cooling as standard.

擠出機可選擇地安裝一個或多個雙螺桿側(cè)向加料器，它們同機筒的側(cè)面相連。這樣就需有一個特殊的帶有開口的機筒單元，這樣螺桿就可帶有針對側(cè)向加料的幾個預留位置從而獲得側(cè)加料的*優(yōu)選擇性。側(cè)加料帶有由無級跳速電機驅(qū)動的長徑比10的雙螺桿，整個側(cè)加料系統(tǒng)的機筒也同樣有水冷卻。

the extruders are supplied complete with a stainless steel volumetric hopper feeder with a “spiral type” screw and with a stirring arm above the feeding screw. the hopper feeder can optionally also be equipped with twin screws.

擠出機安裝了帶有“螺旋型螺桿”以及喂料螺桿上方攪拌臂的不銹鋼體積料斗加料器。料斗加料器可選擇地配備雙螺桿。

the 32 l/d extruder is, as standard, supplied with a vacuum zone on one of the barrel modules and the 40 l/d also have an additional atmospheric vent opening which can be converted to vacuum. the vacuum vent zone has a stainless steel vent port housing which is equipped with a sight glass and vacuum regulator with gauge. the housing is connected to a large vacuum filter and to a vane type vacuum pump mounted in the sub cabinet. further the extruders are supplied with a torque limiter on the motor drive shaft as well as a large, clear vision control panel with symbols for all functions.
