Basic Mechanical Engineering Question and Answer

1.       What is Kelvi-Plank law? Kelvi-Plank law is state that it is impossible for any device that operates on a cycle to receive heat from a single reservoir and produce a net amount of work. 100 % efficient heat engine cannot find 2.       What is the function of diffuser in Compressor? In Fluid Mechanics Bernoulli’s Equation pays a vital role to learn more about diffuser performance. Diffuser is one of the components in a simple centrifugal compressor. Downstream of the impeller in the flow path, diffuser mainly work as converter where it high velocity to low velocity (mainly kinetic energy convert). 3.       What is the relation between C and K? Relation between Kelvin and Celsious is   K = °C + 273.15   °C = K - 273.15 4.       What is the Aeroplane compressor system? There are three types of air compressor used in Aeropalne compressor system a.        Axial Flow b.       Centrifugal flow c.        Centrifug

Essential parts of Jacqard Machine/Knitting Machine

1.       Carrier 2.       Yarn feeders 3.       Carrier stopper 4.       Carrier rail 5.       Needle bed 6.       Gripper and cutter device                  Carrier: Carries the yarn Yarn feeder: Feed the yarn to the needle beds gap. Carrier stopper: Stop the carriers at both ends of the carrier rails. Carrier rail: Rail for the carrier. Needle bed: Parts such as needles, jacks and select jacks are arranged on this needle bed.  Gripper and cutter device: Device to cut and hold the yarn.

Tension Equipment of Jacqard Machine/Knitting Machine

Top Tension Equipment  1.       Tension disk 2.       Tension equipment Left side tension equipment (for DSCS) 3.       Side tension 4.       Encoder 5.       Yarn sending roller Right side tension equipment       3. Side tension Tension disk: Adjust the tension of the yarn. Tension equipment: Detect the yarn breakage. Side tension: Absorb the slack of the yarn when the carriage reverses. Encoder: Measure the length of provided yarn. Yarn sending roller: Reduce the resistance for supplying the yarn to yarn feeder by rotating at high speed.

Function of Jaqard Machine main components

Function of  Jaqard Machine main components  are given bellow Operation Panel: Display the knitting data to confirm and modify. Operation Bar: Switch for the operation to drive and stop the carriage. Carriage: Control the motion of the needles and carries. Fabric off Plate: Drives off and releases the knitting fabric downward to the front of the machine. Main roller: Pull down the fabric. Set up Needle: Device to start knitting with the part not hooked on the needle. Emergency power off switch:   Energies controller and displays opening screen on the operation screen by turning to the right. Turn to the left ti turn off the power.  Drive power switch: Energizes each part of machine and displays menu screen on the operation screen by pressing after turning on the emergency power off switch. This switch is only for on.
