Q7. What is tranformer work in elevator
Transformers are used in elevators to convert high voltage electricity to lower voltage for safe operation.
Transformers step down the voltage from the building's power supply to a level safe for the elevator's motor and control system.
They also help regulate the voltage to ensure consistent performance.
Transformers can be located in the elevator machine room or in the control panel.
Examples of transformers used in elevators include isolation transformers, autotransformers, an...read more
Q8. All types flow meter working and installing
Flow meters are devices used to measure the flow rate of a fluid in a pipe or conduit.
Different types of flow meters include electromagnetic, ultrasonic, vortex shedding, and turbine meters.
Flow meters can be installed in various ways, such as inline, insertion, or clamp-on.
Proper calibration and maintenance are essential for accurate flow measurement.
Examples of flow meter manufacturers include Siemens, Emerson, and Endress+Hauser.

Q9. Types of chiller & cooling towers?
Types of chillers include air-cooled, water-cooled, and absorption chillers. Cooling towers can be classified as mechanical draft or natural draft.
Air-cooled chillers use air to remove heat from the refrigerant.
Water-cooled chillers use water to remove heat from the refrigerant.
Absorption chillers use a heat source to drive the refrigeration cycle.
Mechanical draft cooling towers use fans to move air through the tower.
Natural draft cooling towers rely on the natural convection...read more
Q10. Types of power Transmission system
Power transmission systems are used to transmit mechanical power from a source to a load.
Mechanical power can be transmitted through various types of power transmission systems.
Common types include belt drives, chain drives, gear drives, and shaft drives.
Belt drives use a belt to transmit power between two pulleys.
Chain drives use a chain to transmit power between two sprockets.
Gear drives use gears to transmit power between two shafts.
Shaft drives directly connect the source...read more
Q11. What is Brake coil work
Brake coil work refers to the functioning of the electromagnetic coil in a brake system.
Brake coils are used in electromagnetic brakes to generate a magnetic field that attracts the brake disc or rotor, causing it to slow down or stop.
The coil is energized by an electrical current, which creates a magnetic field that pulls the brake disc or rotor towards it.
The strength of the magnetic field can be adjusted by varying the amount of current flowing through the coil.
Brake coils...read more
Q12. Total body test taking blood sample
Total body test involves taking a blood sample for analysis.
Total body test is a comprehensive health assessment that may include blood tests to check for various health markers.
Blood samples are typically taken from a vein in the arm using a needle and syringe.
The blood sample is then sent to a laboratory for analysis to assess various aspects of health such as cholesterol levels, blood sugar levels, and organ function.
Q13. Hydraulic working problem
