introduction:Solenoid valve structure Solenoid valves are industrial equipment controlled by electromagnetism,It is a basic element of automation used to control fluids,actuator,Not limited to hydraulics、pneumatic。Used in industrial control systems to adjust the direction of media、Flow rate、Speed and other parameters。The solenoid valve has a closed chamber,Through holes are opened at different positions,Each hole is connected to a different tubing,In the middle of the cavity is a piston,On both sides are two electromagnets,The magnet coil on which the valve body is energized will be attracted to which side,Different drain holes are opened or closed by controlling the movement of the valve body,The oil inlet hole is always open,The hydraulic fluid goes into the different drain lines,The piston of the cylinder is then pushed by the pressure of the oil,The piston in turn drives the rod,The piston rod drives the mechanism。 How much do you know about the structure of the solenoid valve?The following Feng Ye Xiaobian will take

introduction:①Transport capacity:The conveying capacity of the conveyor refers to the amount of material transported per unit time。When conveying bulk materials,Measured by the mass or volume of material transported per hour;When conveying into a piece,Based on the number of pieces transported per hour。 ②Conveying speed:Increasing the conveying speed can improve the conveying capacity。When the conveyor belt is used as the traction part and the conveying length is large,The speed of transport is increasing。However, high-speed belt conveyors need to pay attention to vibration、Noise and start-up、Braking and other problems。For the conveyor with the chain as the traction part,The conveying speed should not be too large,To prevent increased power load。Conveyors for simultaneous process operation,The conveying speed should be determined according to the production process requirements。

introduction:Magnetic couple type rodless cylinder principle Magnetic couple type rodless cylinder is the piston is made of magnetic material,No mechanical connection to the actuator,Completely rely on magnetic traction actuator action。Magnetic coupling rodless cylinder:A magnetically coupled rodless cylinder is mounted on the piston with a set of permanent magnetic rings of high magnetic strength,In this way, the magnetic line of force acts through the thin-walled cylinder with another set of magnetic rings sheathed outside,Because the two sets of magnetic rings are oppositely magnetic,It has a strong suction force。When the piston is pushed by air pressure in the cylinder,Under the magnetic force,The magnetic ring inside the outer slider is affected by the magnetic field lines of the magnetic ring on the piston,Do synchronous movement。
