Q1. What is the working principle of a hydraulic press?
Ans. 
Hydraulic press works on the principle of Pascal's law, which states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.
• Hydraulic press uses a hydraulic cylinder to generate a compressive force.

• When a force is applied to the small piston, it creates pressure in the enclosed fluid.

• This pressure is transmitted through the fluid...read more

Q2. What is a servo valve, and how does it work?
Ans. 
A servo valve is a type of valve used in hydraulic systems to control the flow of fluid by varying the size of the flow passage.
• Servo valves are used in applications where precise control of fluid flow is required, such as in aircraft control systems.

• They work by using an electrical signal to move a spool inside the valve, which in turn adjusts the size of the flow passage.

• The movement of the spool is proportional to t...read more

Q3. What is the step-by-step process for opening a profil valve?
Ans. 
The step-by-step process for opening a profil valve involves several key actions.
• Ensure the valve is in the closed position before starting.

• Locate the valve handle or actuator.

• Turn the valve handle or actuator counterclockwise to open the valve.

• Monitor the pressure or flow rate to ensure proper operation.

• Close the valve by turning the handle or actuator clockwise when finished.

• Perform any necessary maintenance or inspe

Q4. What is the difference between a servo valve and a proportional valve?
Ans. 
A servo valve is used for precise control of flow rate, while a proportional valve is used for controlling the flow rate proportionally to the input signal.
• Servo valves are typically used in applications where precise control of flow rate is required, such as in aerospace or industrial automation.

• Proportional valves are used to control the flow rate proportionally to the input signal, making them suitable for applicati...read more

Q5. Can you explain how to read a hydraulic circuit and describe its various parts along with their functions?
Ans. 
A hydraulic circuit consists of various components like pumps, valves, cylinders, and hoses that work together to control the flow of hydraulic fluid.
• Hydraulic pump: generates the flow of hydraulic fluid

• Valves: control the direction and pressure of the fluid

• Cylinders: convert fluid power into mechanical power

• Hoses: transport the fluid between components

• Reservoir: stores the hydraulic fluid

• Filters: remove contaminants f

Q6. How should preventive maintenance be planned on a daily basis?
Ans. 
Preventive maintenance should be planned based on equipment criticality, historical data, manufacturer recommendations, and available resources.
• Identify critical equipment that needs regular maintenance to prevent breakdowns.

• Refer to historical data to determine common issues and plan preventive measures accordingly.

• Follow manufacturer recommendations for maintenance schedules and procedures.

• Allocate resources such as ...read more

Q7. What are MTTR (Mean Time to Repair) and MTBF (Mean Time Between Failures)?
Ans. 
MTTR is the average time taken to repair a failed system, while MTBF is the average time between failures.
• MTTR measures how quickly a system can be restored after a failure

• MTBF measures the average time a system operates before experiencing a failure

• MTTR = Total downtime / Number of failures

• MTBF = Total uptime / Number of failures

Q9. What is the difference between a flow control valve and a relief valve?
Ans. 
Flow control valve regulates the flow rate of a fluid, while relief valve protects equipment from overpressure by releasing excess fluid.
• Flow control valve is used to regulate the flow rate of a fluid in a system.

• Relief valve is designed to protect equipment from overpressure by releasing excess fluid to prevent damage.

• Flow control valve is typically used to control the speed of hydraulic cylinders or motors.

• Relief val...read more
