Lalgarhia Hospital Interview Questions and Answers

Ampere increases when motor runs in shut off head.

• Ampere is the measure of electrical current.

• Shut off head is the maximum head that a pump can generate.

• When the motor runs in shut off head, it experiences maximum resistance, causing the current to increase.

Ampere decreases because current flow is directly proportional to current.

• Current flow and amperage are directly related.

• As current flow decreases, amperage decreases.

• Ohm's Law states that amperage is equal to voltage divided by resistance.

Pressure cup is used to measure the pressure of lubrication oil in the motor.

• Pressure cup is attached to the motor to measure the pressure of lubrication oil.

• It helps in ensuring that the oil pressure is within the recommended range.

• If the pressure is too low, it can cause damage to the motor.

• If the pressure is too high, it can cause oil leaks and other issues.

• Regular monitoring of oil pressure using pressure cup can help in preventing motor breakdowns.

To reduce the temperature, we can adjust the thermostat or use cooling methods.

• Adjust the thermostat to a lower temperature

• Use fans or air conditioning to cool the room

• Apply a cold compress to the body

• Drink cold water or other cold beverages

• Take a cool shower or bath

The type of stator refers to the design and configuration of the stationary part of an electric motor or generator.

• The type of stator can vary depending on the specific application and motor design.

• Common types of stators include squirrel cage, wound rotor, and permanent magnet stators.

• Squirrel cage stators are widely used in induction motors and consist of laminated iron cores with copper or aluminum bars embedded in slots.

• Wound rotor stators have three-phase windings connec...read more

Fire is a chemical reaction that releases heat and light. Fire load refers to the amount of combustible material in a given area.

• Fire is a rapid oxidation process that produces heat and light

• Fire load is the amount of combustible material in a given area

• Fire load can include furniture, paper, wood, and other flammable materials

• The higher the fire load, the greater the risk of a fire spreading quickly
