6. Fill in the appropriate words and expressions into the extract below and translate it into Russian:

diesel engines, component, power, hydraulic power, torque converters, electric motors, steam-powered engines

Rigs are classified by the source of power. The …… to operate everything on a mechanical or power rig, comes from …… that are compounded together. The drawworks, the rotary system, mud pumps are powered directly by the engines. Belts, pulleys, sprockets, and chains connect each …… to the engines. Mechanical rig uses ……, clutches, and transmission powered by its own engines, often diesel. On electric rigs – the major items of machinery are driven by ……, usually with power generated on - site, using internal combustion engines. Hydraulic rigs primarily use …….. Pneumatic rigs are primarily powered by pressurized air. Steam rig uses …… and pumps. (They became obsolescent after middle of 20th century.)

 

 

7. Translate the sentences with the help of the text:

1. Существует два средства для передачи энергии компонентам буровой вышки: механические и электрические.

2. До последнего времени большинство буровых были механические – это значит, что энергия двигателя передавалась компонентам вышки с помощью механических средств.

3. На механически управляемой вышке, энергия от двигателей, передаётся лебёдкам, насосам и другому машинному оборудованию через агрегат, который называется соединением.

4. Соединение состоит из муфт, замков сцепления, цепных колёс, ремней, подъёмников и валов, функцией которых является передача энергии.

5. На электро-дизельных буровых, дизельные двигатели приводят в действие большие электрические генераторы.

6. Генераторы, в свою очередь, производят электричество, которое посылается через провода переключателю и контрольной передаче.

7. Отсюда электричество проходит через дополнительные провода к электрическим моторам, которые непосредственно присоединены к лебёдкам, буровым насосам и роторному столу.

8. Одним из преимуществ электро-дизельной системы над механической, является прекращение использования тяжёлого сложного соединения и цепного привода.

9. Другим преимуществом является снижение шума на буровой, потому что двигатели могут работать на отдалённом расстоянии.

10. Расположение буровой не является стандартным: первичные двигатели, лебёдки, насосы, ротор могут быть установлены в зависимости от предпочтений подрядчика.

11. Системе подъёмных механизмов, во время поднятия колонны или во время её работы, требуется наибольшее количество мощности.

12. Второй, по потреблению энергетической мощности, является циркуляционная система.
