1 The air pressure is normal, but the air continuously leaks from the pressure controller vent D or D. The tympanic membrane of the valve is in contact with the deflation valve and is not tightly fitted, forming a gap and leaking gas; the tympanic membrane spring is damaged and fails, and the valve tympanic membrane cannot be pressed. Check the seal of the valve tympanic membrane and the deflation valve. If it is damaged, replace it with a new one; replace the tympanic membrane spring.
2 After the air compressor stops pumping, the vent hole D or C does not deflate, but the air pressure drops rapidly. The intake Check Valve is aging, damaged, and the seal is not tight and leaks; the intake check valve spring is damaged and fails. Check the intake check valve and its sealing. If it is damaged, replace it with a new one; replace the intake check valve spring.
3 When the air pressure is higher than 0.70 Mpa, the adjusting screw is too tight, the compression of the tympanic membrane spring is too high, and the venting pressure of the tympanic membrane of the valve is too high. The electromagnetic flowmeter screws the adjustment screw a little to reduce the compression of the tympanic membrane spring.
4 The air pressure is higher than 0.70 Mpa, and it is continuously rising, but the air is not released from the vent hole D or C. The tympanic spring is stuck; the air hole on the deflation valve is blocked; the deflation check valve spring is stuck; the valve stem Was stuck. Replace the tympanic spring; unblock the air vent on the bleed valve; replace the bleed check valve spring; trim or replace the valve stem.
5 Air leaks between the upper and lower casings, and bubbles are generated after being coated with washing powder water. The upper and lower casing castings are defective; the sealing ring between the upper and lower casings is damaged or the fastening bolts are loose; the tympanic membrane of the valve is aged, so that air leaks from the adjusting screw. Wipe the surface of the case, repair the defect with a metal repair agent; replace the seal ring or tighten the bolt; replace the valve tympanic membrane.
6 The air pressure is less than 0.65 Mpa and is continuously lowered, but the gas is always discharged from the pressure controller vent D. The valve tympanic membrane, tympanic membrane spring or deflation valve is damaged, the seal is ineffective; the venting hole C is blocked; the deflation check valve is leaking; the deflation check valve spring is lost and fails; the skin is aging and leaking. Check the sealing condition of the valve tympanic membrane, tympanic membrane spring or deflation valve. If it is damaged, replace the new part to clear the venting hole C; replace the deflation check valve; replace the bleed check valve spring; replace the cup.
7 When the air pressure is lower than 0.65 Mpa, the adjusting screw is too loose, the venting pressure of the valve tympanic membrane is low, and the deflation valve is aging and leaking. The electromagnetic flowmeter screws the adjustment screw a little; replace the bleed valve.
The common faults and troubleshooting methods of the electromagnetic flowmeter controller are simply listed as seven items, as follows:
