Understanding the Parts and Features of a Pneumatic Foot Lifter
Strain Change
The strain swap is a vital element that detects the presence of compressed air within the system. When the strain reaches a predetermined stage, the swap journeys, activating the solenoid valve.
Solenoid Valve
The solenoid valve is an electromagnetically operated valve that controls the movement of compressed air. When activated, the solenoid valve opens, permitting air to enter the air cylinder.
Air Cylinder
The air cylinder is a mechanical actuator that converts the compressed air into linear movement. As compressed air enters the cylinder, the piston strikes, elevating or decreasing the foot lifter.
Foot Lifter
The foot lifter is the bodily mechanism that lifts the presser foot of the overlock machine. It’s related to the air cylinder and strikes in response to the air strain.
Foot Pedal
The foot pedal is the consumer interface that triggers the foot lifter. When the operator presses the foot pedal, it prompts the strain swap, initiating the sequence of occasions that elevate the presser foot.
Adjustment Screw
The adjustment screw permits the operator to fine-tune the peak to which the foot lifter raises the presser foot. This ensures exact adjustment for various cloth thicknesses and stitching methods.
