Steam solenoid valve fault detection techniques

Steam solenoid valves after withstand electrical control signal can take the initiative to open or close the valve, to achieve off pipe steam or flow conditioning control, and thus the system in the steam temperature, flow, pressure and other parameters automatically adjust or long-distance control solenoid valve. Because the steam solenoid valve to use textiles, printing, plastics, chemical, pharmaceutical, rubber, building materials, machinery, electrical appliances, food, such as automatic control system, the use of extremely broad. Following small for us to introduce, steam solenoid valve problems arise after the investigation tips.
1, if the lugs loose or thread off, electric solenoid valve shall be fastened thread.
2, coil burn, remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned out.
3, steam solenoid valve stuck. Cooperation gap solenoid valve slide valve sleeve and spool with a small (less than 0.008mm), are usually one-piece installation, when a mechanical impurities into or too little lubricant, it is easy to get stuck.
4, the lack of air pressure leakage will form, making forced opening and closing valve is difficult, because the gasket is damaged or slide valve wear and the formation of several cavity channeling gas.

It turns out that foot pumps

It turns out that foot pumps, like the vast majority of hand pumps, have a flap, either plastic or aluminum, whose function is to block the entrance of the air once the inflation nozzle has been inserted into the valve of the chamber . Up to that point everything is correct and easy. But as is normal, these pumps and other pumps are designed for standard size wheels, either road 700cc (28 "or" 29 ") or mtb 600cc (26") or even folding or bmx 20 "( Ertro 406) In all of them the radius crossing, or the angulation of these if not crossed, allows to perfectly unfold the locking flap, because there is enough distance to the hub. 3/8 (Ertro 349) can not be done easily, since if you manage to enter it, then it costs a lot to remove it without forcing it out because of the small size of wheel and short distance between the intersection of the spokes and the hub.

Cryogenic solenoid valve troubleshooting

There is a rather special class in many types of electromagnetic valve solenoid valves, the solenoid valve is low. Ultra-low temperature solenoid valve with a long life a bit, and its simple structure, easy maintenance, the use of special valve made of stainless steel, has a good wear resistance and low temperature resistance, widely used in the nuclear industry, military, petrochemical, shipbuilding, aerospace industrial automation control and other fields. So in daily use, among other factors due to improper operation will encounter this kind of problem.
1, liquid cryogenic solenoid valve prone to failure problems are mainly consumable parts and seals and other coil, the coil burned out due to work overload caused the seal itself is wearing parts, mostly as a result of the prolonged natural abrasion.
2, cryogenic solenoid valve at work, if the vibration occurs frequently, it is very likely to cause damage to the valve member, and therefore low temperature solenoid valve maintenance, should guarantee the stability of the work environment, regular solenoid valve components fixed, such as nuts and bolts and the like.
3, regularly clean up the demolition cryogenic solenoid valve internal impurities, and check whether the various parts of the hydraulic solenoid valve has serious wear and tear, and to consider the replacement or repair damaged parts according to the actual situation.
4, at low temperature solenoid valve disassembly time, to conduct power and other ancillary closing the connection, and pay attention to the order of installation in various parts of the solenoid valve during the disassembly.
5, under the conditions allowed, if the solenoid valve in the workplace is important, be equipped with a dedicated maintenance personnel, to ensure the stability of the work of the solenoid valve and low failure rate. In order to make it work more efficiently, lower maintenance costs, longer life.
