Setting electromagnetic pulse valve injection time refers to the time pulsed electromagnetic valve is energized, rather than pulse valve diaphragm moves in time. For example: set the pulse valve energizing time is 50ms TMF-62S rectangular electromagnetic pulse valve, pulse valve diaphragm moves the time to go beyond 100ms /. Results occur within the pulse valve injection time of the cleaning result is the key peak airflow irregularities, rather than through the length of the continuous stream of time. It can be seen, high-quality electromagnetic pulse valve cleaning results will be a major influence of extreme electromagnetic pulse valve function check: 1, open voltage test access at the inlet air pressure electromagnetic pulse valve nominal pressure cleaner air input to the solenoid valve 85% of nominal voltage, a width of 0.03s electrical signal, to reflect 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, 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, continue 60min electromagnetic pulse valve, gas leakage reflect the situation on the part of the sealing electromagnetic pulse valve. 4, insulation resistance test (1) 500V, range limitations of 0MΩ ~ 500MΩ TMF-25 rectangular electromagnetic pulse valve, accuracy level of 1 megohm table, the premise of the rule in the case, the measurement of electromagnetic coil housing insulation resistance . (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
