Detailed Product Description: | Most will use pulse valve, pulse valve but do not know who you might run into trouble worry, brightly lit dust for many years to share some experiences, electromagnetic pulse valve failure phenomenon in the development and production of pulse valve Analysis: input signals electromagnetic pulse valve , the pilot head does not move TMF-76S rectangular electromagnetic pulse valve, the diaphragm does not move, the valve is not working. Line barrier; voltage is too low; due to improper installation site, the pilot moving the first column stuck. Input electrical signal, the pilot head movement column in place beating pulse valve can not be blowing. Unloading hole plugging poor exhaust, the pilot head movement columns have card phenomenon. Input electrical signal, the diaphragm in place beating pulse valve can not be blowing. Pilot head movement column in the beating, large diaphragm orifice wear increases, the damping effect becomes small; small membrane orifice has blocked, unloading poor exhaust. Electrical signal disappeared, the pilot head movement column can not be reset. Burr or impurities, so that the moving column stuck; spring fatigue, lack of resilience; orifice has blocked, or make life difficult for pressurized gas pressure is low. Electrical signal disappears, the diaphragm can not be reset shut. There blocked orifice, damping effect is too large, the gas pressure can not be put in place; static pressure is low; not timely relief hole closed. Electrical signal disappears, the diaphragm can not be reset closed. Blocked orifice; unloading holes are not closed. Pilot valve coil heat, burn. High voltage; predetermined voltage DC24V, AC220V input voltage to the current is too large. Electromagnetic pulse valve function inspection: 1, the turn-on voltage test nominal pressure clean air, 85% of nominal input voltage of the access port in the intake air pressure in the solenoid pulse valve solenoid valve, a width of an electrical 0.03s signal, reflect on whether the normal electromagnetic pulse valve is open. 2, the closure pressure in the intake port access test air pressure electromagnetic pulse valve is 0.1MPa clean air, enter the closed valve electrical signal TMF-62S rectangular electromagnetic pulse valve, reflect electromagnetic pulse valve can be closed securely . 3, the pressure in the intake port function test access electromagnetic pulse valve air pressure is 0.8MPa clean air continues 60min, to reflect the status of each gas leak sealing parts of the electromagnetic pulse valve. 4, insulation resistance test (1) 500V, range limitations of 0MΩ ~ 500MΩ, accuracy level of 1 megohm table, the premise of the rule in the case, the measurement of electromagnetic coil insulation resistance of the shell. (2) placing the valve temperature and humidity chamber, the temperature is set at 35 degrees and a relative humidity of 85% under the premise, applied 50Hz, sinusoidal AC voltage of 250V between the electromagnetic coil and the body, which lasted 1min, reflect on whether there is a breakdown scene. 5, anti-vibration test the valve fixed to the vibration test tasks bench TMF-40S rectangular electromagnetic pulse valve, receiving a vibration frequency of 20Hz, the full amplitude of 2mm, vibration lasted 30min after each partial reflection valve fasteners can No loose sight, whether the normal task. 6, the diaphragm service life test in the intake port access to the electromagnetic pulse valve nominal pressure clean air, enter the width of the electromagnetic pulse valve is 0.1s, 3s from the nominal voltage value and record valve continuation or accumulated Task times |
