Machine operation and maintenance 1. What does the 3 P principle mean? : r1 prevention, proactivity, productivity : r2 process approach, productivity, proactivity : r3 promotion, process approach, proactivity : r4 prevention, process approach, productivity : r1 ok -- 2. How do we calculate the “performance rate”? : r1 (number of pieces x cycle): time of possible equipment operation - downtime : r2 Equipment operating time: equipment operating time : r3 usage rate x performance rate x quality measure : r4 number of units produced: time of operation of the device : r1 ok -- 3. Define "risk" : r1 acceptable form of the activity : r2 Possibility of hazard activation : r3 object property cause negative effect : r4 the probability with which an event can occur : r1 ok -- 4. What does FTA mean? : r1 tree fault analysis : r2 event tree analysis : r3 analysis of the mode and effect of failures : r4 analysis of failure, sequence and criticality : r1 ok -- 5. Define the risk of maintenance : r1 the product of the probability of failure and consequence : r2 failure probability value : r3 inventory of possible fault types and causes : r4 the probability with which an event can occur : r1 ok -- 6. What does a compact maintenance audit not include? : r1 Consequences of failure : r2 maintenance benchmarking : r3 maintenance outsourcing : r4 operational reliability quantification : r1 ok -- 7. What is not the objective of benchmarking? : r1 risk analysis : r2 cost savings : r3 accelerate the change process : r4 increase customer satisfaction : r1 ok -- 8. Explain the term "outsourcing" : r1 the use of external resources to ensure performance that is not one of the company's key capabilities : r2 process of comparing and measuring products, processes and methods : r3 collecting data on process performance and customer needs : r4 Defining goals to improve your own activities : r1 ok -- 9. What does bath curve express? : r1 divides the product life cycle into zones : r2 shows the difference between the required and actual achieved reliability : r3 shows the wear rate of the product : r4 shows the progress of product realization : r1 ok -- 10. II. zone of the life cycle zone of the object represents : r1 period of normal operation : r2 period of frequent disturbances : r3 aging period r4 period of growth of failure intensity due to aging of material : r1 ok Show more Show less -- 11. The shutdown and decommissioning of the facility takes place during : r1 III. period : r2 I. period : r3 II. period : r4 IV. period : r1 ok -- 12. The reliability data bank is important for : r1 reliability management : r2 benchmarking : r3 feedback : r4 device rating : r1 ok -- 13. Methods of reliability analysis do not include : r1 benchmarking : r2 trend : r3 histogram : r4 Pareto diagram : r1 ok -- 14. What is Ishikawa diagram? : r1 cause and effect diagram : r2 shows the importance of each category : r3 shows the evolution of changes in reliability indicators over time : r4 the only method of reliability management : r1 ok -- 15. The graphical representation of data distribution using a bar graph with columns of the same width is called: : r1 histogram : r2 Ishikawa diagram : r3 trend : r4 Pareto diagram : r1 ok -- 16. What does a serial reliability model look like? : r1 failure of any element results in failure of the whole system : r2 A system failure occurs when all of its elements fail : r3 A system that requires only one operable element to operate : r4 none of the options : r1 ok -- 17. Define the rated performance class for continuous load : r1 the machine can operate for unlimited time in accordance with the requirements : r2 the machine can operate for a limited period of time starting from ambient temperature : r3 the machine can operate in duty cycles as required : r4 the machine can operate at the appropriate load and speed for an indefinite period of time : r1 ok -- 18. The performance at which the machine can operate at a constant load until it reaches a steady temperature, achieving the same warming of the stator winding as the average warming value during the duty cycle is called: : r1 Rated performance for equivalent load : r2 nominal power for periodic load : r3 Rated performance for continuous load : r4 nominal performance for short - term operation : r1 ok -- 19. The amount of workpieces machined by a given device per unit of time is referred to as : r1 technological performance : r2 actual power : r3 cycle power : r4 working power : r1 ok -- 20. Tribology deals with : r1 processes of friction, wear and lubrication : r2 Description and calculation of work output : r3 correct maintenance policy : r4 by determining the cyclic loss : r1 ok
