Solenoid Valve 24vdc- China Manufacturers Suppliers Factory

Select the correct cylinder according to the following conditions:

1. According to the type of cylinder:

Choose the type of cylinder according to the working requirements and conditions.  Use a heat-resistant cylinder in a high temperature environment.  In a corrosive environment, the use of corrosion – resistant cylinder.  Install a dust cover on the protruding end of the piston rod in harsh environments such as dust.  When no pollution is required, the cylinder without oil or oil lubrication should be selected.

2, according to the size of the force:

According to the size of the load force to determine the cylinder output thrust and tension.  In general, the acting force of the cylinder required by the theoretical equilibrium condition of uniform external load is multiplied by the coefficient 1.5~2.0, so that the output force of the cylinder is slightly surplus.  The cylinder diameter is too small, the output force is not enough, but the cylinder diameter is too large, so that the equipment is cumbersome, the cost increases, and increases the consumption of gas, waste energy.  In the fixture design, should try to use the expansion mechanism, in order to reduce the cylinder size.

3. According to the stroke of the piston:

And the use of the occasion and the stroke of the mechanism, but generally do not choose full stroke, to prevent the piston and cylinder head collision.  If used for clamping machine structure, it should increase the allowance of 10~20mm according to the calculation required stroke.  It should be selected as standard trip as far as possible to ensure the supply speed and reduce the cost.

4. According to the movement speed of the piston:

Mainly depends on the cylinder input compressed air flow, cylinder inlet and exhaust port size and pipe diameter.  High speed motion is required.  The cylinder movement speed is generally 50~1000mm/s.  For high-speed motion of the cylinder, the intake pipe of large internal passage should be selected;  For the load changes, in order to get slow and steady speed, can choose with throttle device or gas-liquid damping cylinder, it is easier to achieve speed control.  When selecting throttle valve to control the cylinder speed, note that: when the horizontally installed cylinder pushes the load, it is recommended to use exhaust throttle speed regulation;  When vertically installed cylinders lift loads, it is recommended to use intake throttle speed regulation;  When the stroke is required to move smoothly to avoid impact, the cylinder with buffer device should be selected.

1. There are two ways of filter drainage: differential pressure drainage and manual drainage.  Manual drainage must be discharged before the water level reaches the level below the filter element.

2. When adjusting the pressure, please pull up and rotate the knob before turning it, and press the knob for positioning.  Rotate the knob to the right to increase the outlet pressure, rotate to the left to lower the outlet pressure.  Pressure adjustment should be gradually and evenly adjusted to the required pressure value, should not be adjusted in one step.

3, the use of oil feeder: oil feeder using JIS K2213 oil (ISO Vg32 or the same oil).  Please fill no more than eight full cups.  The number 0 indicates the minimum amount of oil and 9 indicates the maximum amount of oil.  Cannot rotate from position 9-0, must rotate clockwise.  A. According to the pipe diameter, flow size, pressure regulation, filtration accuracy and other technical performance parameters, select the air components needed by the system;  ?

B. The filter precision of air filter is 2um, 5um, 10um, 20um, 40um, 70um, 100um seven, according to the quality requirements of the air to choose the appropriate products;

C. When using the pressure reducing valve, try to avoid using the lower limit value of the pressure regulating range, choose the appropriate pressure reducing valve according to the requirements of the use of pressure;

D. Installation sequence: from the inlet end of the air source, connect the air filter, pressure reducing valve and oil mist at one time. The arrow direction on the component shell is the direction of air flow, and no reverse connection is allowed;

E. Air filter and oil mist must be installed vertically with the cup side down;

F. Once the oil mist is countercurrent, it will cause damage and danger to the internal parts, so it should be avoided;

G. During installation and connection, do not mix any impurities such as sealing tape and rust into the pipes.
