Контрольная работа по Английскому языку на тему: "Valves & Actuators: The Path to Greater Efficiency & Performance"

1. Перепишите предложения и определите функцию глагола to have, to be. Переведите предложения на русский язык.

1. Until 20 years ago motor operated valves tended to have motor control centers remote from the valve.

2. The more recent smart actuators have an internal data logger inside which has had the ability to monitor torque output.

3. When valves leak, they are acting in direct opposition to the forces that drive the plant by allowing energy to leave the high energy processes and enter the low.

4. Valves and actuators are critical in almost every aspect of power plant operations.

5. Although the basic technology for most valves and actuators has remained the same, innovative applications and design modifications for problem solving have led to notable improvements in actuator technology.

2. Выберите требуемую форму глагола и переведите предложения на русский язык.

1. Actuators perform different motion sequences, (including, included, to include) linear and (rotated, rotating) motions.

2. If actuators (haven’t received, hadn’t received, wouldn’t receive) a control signal from automation systems, they (wouldn’t have converted, wouldn’t convert) it into a motion.

3. If the valve (leaked, would leak), it (acted, would act) in direct opposition to the forces that drive the plant by allowing energy to leave the high energy processes and enter the low.

4. Miscellaneous trip alarms are also included (monitoring, to monitor) things like starts per hour (insuring, to insure) that the internal contactors are not being overused.

3. Поставьте глагол в скобках в правильную видо-временную форму (Passive voice). Переведите предложения на русский язык.

1. Valves (to expose) to a variety of chemicals, abrasive materials and very high temperatures.

2. The signal (to convert) into a motion so that the control element of the actuating element assumes a corresponding position.

3. Certain practices currently (to adopt) to allow for reliability and maintenance at a power plant.

4. There are also maintenance interval settings that can (to adjust) by the plant operator.

5. Last month valve performance (to monitor) and leaking valves (to detected) due to the introduction of Cycle Isolation testing technology.

4. Дополните таблицу требующимися частями речи. Переведите полученные формы.

Valves and actuators are critical in almost every aspect of power plant operations. They are used in a wide range of applications, including pollution control, feed water, cooling water, chemical treatment, bottom ash and steam turbine control systems. They are exposed to a variety of chemicals, abrasive materials and very high temperatures. They are critical in optimizing efficiency, and they are often the final control element in the operation of a power plant...........

By five years from now, in 2025, a rational assessment of the climate science suggests that, to avoid dangerous levels of global warming, the burning of fossil fuels needs to be heavily proscribed, and mankind should be directing maximum effort towards creating renewable energy power systems. The early transition to renewable energy sources is necessary to improve our ‘green’ credentials and enable the abandonment of fossil fuels, without sacrificing our advanced technological societies. /////////
