Performance test
1, open voltage test
In the air inlet of the electromagnetic pulse valve, connect the
clean air with the nominal pressure of the air source. Input the
electric signal of 85% of the nominal voltage and 0.03s of the
width on the electromagnetic valve to check whether the
electromagnetic pulse valve is open normally.
2, close the air pressure test
In the air inlet of the electromagnetic pulse valve, connect the
clean air with a pressure of 0.1 MPa, input the electrical signal
to close the valve, and check whether the electromagnetic pulse
valve is reliably closed.
3, pressure resistance test
In the air inlet of the electromagnetic pulse valve, the clean air
with a pressure of 0.8 MPa is connected for 60 minutes, and the
leakage of the sealing parts on the electromagnetic pulse valve is
checked.
4, insulation resistance test
(1) Measure the insulation resistance of the electromagnetic coil
to the outer casing under the specified environmental conditions
using a 500V meter with a range of 0MΩ to 500MΩ and an accuracy of
1 meter.
(2) Put the valve in the temperature regulation and humidity
control box, and set the temperature to 35 degrees, and the
relative humidity is 85%, apply a 50Hz, 250V sinusoidal AC voltage
between the electromagnetic coil and the valve body for 1min. Check
for breakdown.
5, anti-vibration test
The valve is fixed on the vibration test bench, and after the
vibration frequency is 20 Hz, the full amplitude is 2 mm, and the
vibration is 30 min, the fasteners of each part of the valve are
checked for looseness and the work is normal.
6, diaphragm life test
The clean air of the nominal pressure is connected to the air inlet
of the electromagnetic pulse valve, and the nominal voltage value
of the width of 0.1 s and the interval of 3 s is input on the
electromagnetic valve, and the number of consecutive or cumulative
operations of the valve is recorded.
