How to adjust the cylinder speed

The cylinder is a component that uses compressed air to guide movement in the cylinder for reciprocating motion. The movement speed of cylinder is determined by the expansion speed of the air in the cylinder, and can be adjusted in the following three ways: span>

1. The speed of the cylinder can be achieved by adjusting the flow rate of the intake air, such as regulating valves, throttle valves, etc.

2. If different speeds are required, multiple air paths can be used to achieve it.

3. The combined output of multiple air circuit controls can achieve a variety of cylinder speeds.

In addition, lubrication can be used to improve the friction of the piston moving in the cylinder, thereby speeding up the movement of the piston.

Generally, pneumatic speed control valves (one upper and lower) are installed on the pneumatic cylinder. Now take the end of the cylinder with the piston rod as the top and the end without the piston rod as the bottom. Then, if you want the cylinder to rise slower, turn down the speed control valve for exhaust air at the top (do not adjust the bottom);if you want the cylinder to descend slowly, turn down the speed control valve for the exhaust air at the bottom (do not adjust the top);On the contrary, if you want it to rise or fall quickly, turn it up. Try not to adjust it up and down at the same time. Adjust it a little and try it out, then adjust it a little more, and it will be adjusted to the ideal speed in no time.

Why is the cylinder speed so slow?

1: The air flow rate has decreased. It may be that the filter is clogged or the reversing valve is stuck.

Two: The cylinder piston sealing ring has expanded. If the air flow is not filtered well, or the drainage is not good, and the oil is not supplied in place, it will also cause the sealing ring to expand, thus causing the cylinder Movement slows down.

When the cylinder speed is slow, check whether the intake pipe and exhaust muffler are blocked.

First check the pressure gauge reading on the filter pressure reducing valve to see if it reaches the required air pressure.

Secondly, check whether a speed regulator is installed on the air pipe of the cylinder head. If so, adjust it.

Last air path andThe cylinder may be clogged, and the solenoid valve may also be clogged. Not enough accommodation.

The sealing ring inside is broken and leaking internally. Pull out one side of the trachea and move it in the other direction to see if there is any small air leakage in the removed tube.
