MDE Unit 19 pneumatic clutch

Question:
With reference to pneumatic clutches used for medium-speed main propulsion purposes, which TWO interlocks are necessary for proper clutch operation?

B) Clutch temperature and air pressure

Question 3:
What component in an air-operated radial tyre type clutch provides the frictional force necessary for torque transmission?

B) Radial tyres

With reference to pneumatically operated friction clutches, what is the effect of oil contamination on the friction pads?

 

B) Decreased friction causing slippage and reduced clutch efficiency

Question:
With reference to pneumatically operated friction clutches, what is the effect of angular misalignment?

B) Increased risk of friction pad wear and potential clutch slippage

Question:
With reference to pneumatic clutches used for medium-speed main propulsion purposes, how can the clutch be engaged in the event of a failure of the control system?

C) Engage the clutch using a manual override mechanism or emergency procedure

Question 2:
In a pneumatic clutch system, what component is primarily responsible for applying the clamping force to the clutch plates?

B) Pneumatic actuator

Question 2:
In a reduction gearing and pneumatic clutch arrangement, which protection device is commonly used to avoid damage from excessive torque?

B) Torque limiter

Question 4:
Which of the following is a typical advantage of using an air-operated radial tyre type clutch in a diesel engine propulsion system?

A) High torque capacity and smooth engagement

Question 2:
How is the engagement of an air-operated radial tyre type clutch typically controlled?

 

B) By varying the air pressure supplied to the clutch

Question 1:
In a diesel engine propulsion system, what is the primary function of an air-operated radial tyre type clutch?

B) To engage or disengage the engine from the propulsion system

Question:
With reference to pneumatically operated friction clutches, what is the effect of reduced air pressure?

B) Decreased engagement force causing incomplete clutch engagement or slippage

Question 4:
Which protection device helps to ensure that the pneumatic clutch operates correctly and safely in the event of an air pressure failure?

B) Manual override system

Question 5:
In the context of a reduction gearing and pneumatic clutch system, which device is used to monitor and protect against abnormal vibration?

A) Vibration sensor

Question 3:
What is the purpose of a pressure relief valve in the pneumatic clutch system of a propulsion setup?

B) To prevent air pressure build-up

Question 1:
With reference to pneumatic clutches used for medium-speed main propulsion purposes, what is the primary function of the pneumatic system in the clutch operation?

 

B) To engage and disengage the clutch by controlling the air pressure

Question 5:
What is the effect of a loss of air pressure in an air-operated radial tyre type clutch?

C) The clutch will automatically disengage

Question 4:
What is the purpose of the air pressure control system in a pneumatic clutch used in medium-speed main propulsion?

B) To regulate the engagement and disengagement timing of the clutch

Question 3:
How does the release of air pressure affect the operation of a pneumatic clutch?

B) It decreases the engagement force, leading to clutch disengagement

Question 1:
With reference to a reduction gearing and pneumatic clutch arrangement of a propulsion system, which of the following is a protection device typically fitted to prevent excessive gearbox temperatures?

A) Temperature sensor

Question:
With reference to pneumatically operated friction clutches, what is the effect of distorted friction pads?

C) Uneven engagement leading to vibration and potential clutch slippage
