Pulse solenoid valve | Use and maintenance of pulse solenoid valve | Dongjie dust removal
The power-on time of the pulse solenoid valve is the time when the solenoid valve air path is connected, which is also the injection time of the pulse valve. This time can be controlled by non-contact pulse Adjust the pulse width of the instrument, and the adjustment range is seconds.
The main components of the pulse solenoid valve are the valve seat, shell, coil, fixed core and movable core air inlet and outlet. When the coil is not energized, the elastic force of the spring causes the movable iron core to seal the air inlet. At this time, the air path is blocked. When the coil is energized, the movable iron core is sucked, and the iron core is lifted up to open the air inlet nozzle, and the air path is connected, allowing the back pressure chamber of the pulse solenoid valve to vent through the solenoid valve, and the pulse valve injection port is opened to realize the injection of compressed air. After the coil is powered off, the elastic force of the spring causes the movable iron core to seal the air inlet, completing an action process of the solenoid valve.
Use and maintenance of pulse solenoid valve:
When the ambient temperature is higher than ℃, the temperature rise decreases accordingly. For example: when the ambient temperature is ℃, the temperature rise is less than ℃. The third output line of the leaf spring plug of the non-contact pulse controller is connected to one lead wire of each solenoid valve respectively, and C is the common neutral line of the pulse valve, which must be in common with the other lead wire of each solenoid valve. catch. Note that each line should not be damaged, open or short-circuited.
After powering on, the pulse solenoid valve does not work. You should check whether the solenoid valve coil is open or short-circuited. You can use a multimeter to measure the coil resistance, which should be between ohms.
If the solenoid valve buzzes loudly after being energized, you should check whether there are any debris between the movable core and the magnetic isolation sleeve, whether the end faces of the fixed core and the movable core are clean, and whether the exhaust sealing plug is damaged or deformed.
If there is air leakage between the iron core flange and the valve seat, check whether the circular sealing ring is damaged.
After every 10,000 times of operation of the pulse solenoid valve, the magnetic circuit should be cleaned to remove dust and rubber dust, so as not to hinder the work of the movable core.
The pulse solenoid valve should be in a normally closed state, that is, the solenoid valve coil is energized repeatedly for a short period of time, and the duty cycle is . It should not be continuously energized for a long time to avoid electricity burning out the solenoid valve coil.
