10L oxygen machine solenoid valve

The failure of the oxygenator SMC solenoid valve will have a direct impact on the work of the switching valve and control valve, in which the solenoid valve is not working properly is common and should be checked from the following aspects.

(1) SMC solenoid valve coil burned, can be removed from its wire, measured with a multimeter, if disconnected, will make the coil scorched. The reason for this is due to the return of moisture to the coil, resulting in poor edge, so that the magnetic field leakage, so that the current in the coil is too large and burned, so the rain should be prevented from entering the solenoid valve.

(2) Air leakage. Air leakage can cause a lack of air pressure, forcing the forced liquid-controlled one-way solenoid valve difficult to open and close because of a broken gasket or broken spool, resulting in multiple internal cavities.

(3) SMC solenoid valve is stuck. Disassemble the solenoid valve, remove the spool and spool, clean with CCI4, so that the flexible operation of the spool in the valve sleeve. When disassembling, pay attention to the installation order of each part and the location of external wiring to make it reassemble and connect properly, and check whether the nozzle is blocked and the lubricating grease is sufficient.

(4) SMC solenoid valve terminals are loose or disconnected, SMC solenoid valve can not be energized, can be tightened.

SMC solenoid valve is a flammable and explosive gas alarm system, its design should be based on the actual situation and scientific instructions to carry out, electronically controlled normally open solenoid valve can be better in practice, scientific guidance can provide a theoretical basis for the design of the valve. Gas explosion-proof safety valves should be installed in areas where flammable and explosive gases produce leaks, that is, direct leak sources, so these locations should become the place to install explosion-proof solenoid valves.

Considering that gas leaks may spread due to the wind direction or the characteristics of S gas, which can lead to fire, it is important to find out the dead ends that are easily formed after a gas leak, to find out the dead ends that are easily formed after a gas leak, when the ventilation standard is poor, the corner of the wall or the intersection between the beams will form a piece of dead silence, these places should be designed and installed with alarms.
