    德國VOITH(福伊特)Voith轉換器、Voith聯(lián)軸器、VOITH偶合器、VOITH液力偶合器

    We have run two courses, one on Steam Turbines Operation and Maintenance and one on Heavy Duty Gas Turbines Operation and Maintenance - a total of 10 training days. Thanks to the joint collaboration of the Florence and KL teams we have collected more than 30 people from 7 different companies in the region.
    德國VOITH(福伊特)液力偶合器的工作原理以液體為工作介質的一種非剛性聯(lián)軸器,又稱液力聯(lián)軸器。液力偶合器的泵輪和渦輪組成一個可使液體循環(huán)流動的密閉工作腔,泵輪裝在輸入軸上,渦輪裝在輸出軸上。動力機(內燃機、電動機等)帶動輸入軸旋轉時,液體被離心式泵輪甩出。這種高速液體進入渦輪后即推動渦輪旋轉,將從泵輪獲得的能量傳遞給輸出軸。最后液體返回泵輪,形成周而復始的流動。液力偶合器靠液體與泵輪、渦輪的葉片相互作用產生動量矩的變化來傳遞扭矩。它的輸出扭矩等于輸入扭矩減去摩擦力矩,所以它的輸出扭矩恒小于輸入扭矩。液力偶合器輸入軸與輸出軸間靠液體聯(lián)系,工作構件間不存在剛性聯(lián)接。液力偶合器的特點是:能消除沖擊和振動;輸出轉速低于輸入轉速,兩軸的轉速差隨載荷的增大而增加;過載保護性能和起動性能好,載荷過大而停轉時輸入軸仍可轉動,不致造成動力機的損壞;當載荷減小時,輸出軸轉速增加直到接近于輸入軸的轉速,使傳遞扭矩趨于零。液力耦合器的傳動效率等于輸出軸轉速與輸入軸轉速之比。一般液力偶合器正常工況的轉速比在0.95以上時可獲得較高的效率。液力偶合器的特性因工作腔與泵輪、渦輪的形狀不同而有差異。它一般靠殼體自然散熱,不需要外部冷卻的供油系統(tǒng)。如將液力偶合器的油放空,偶合器就處于脫開狀態(tài),能起離合器的作用。

    Under a contract of over US$80 million, GE Oil & Gas will provide North West Upgrading Inc., a Calgary-based, independent company, with centrifugal and reciprocating compressors, centrifugal pumps and air coolers. The new plant will upgrade low-value bitumen from Alberta's oil sands into light, low sulphur products such as diluents and ultra low sulphur diesel as well as other products that can be used by refineries to produce gasoline.

    The partners are working to a framework for the further localized packaging and assembly of additional advanced GE Oil & Gas equipment to benefit Saudi Arabian customers such as centrifugal pumps. More than 17,000 GE Oil & Gas high efficiency centrifugal pumps are installed around the world for process, refinery, water injection, oil pipeline, boiler feed and water-cooling applications. The pumps are fully compliant with API 610-ISO 13709 industry standards and meet the most severe service requirements, including continuous service with high mean time before failure (MTBF). They have been installed with virtually every type of industrial driver including electric motors, gas and steam turbines and diesel and gas engines; and have reached significant perbance milestones such as 14,500 KW/stage and 7,500 rpm.
