Solenoid problems can be grouped into basic categories, including stuck plungers or valves, bad internal windings, and excessive noise. Solenoids are electromechanical devices used to regulate flow and can be coupled to valves or used for mechanical work. Common solenoid problems involve inductive coils and valves, and can cause failure or noise. Troubleshooting varies and may require repair or replacement.
There are many different types of solenoids, although the problems that typically occur with these components can be grouped into a few basic categories. Common solenoid problems include plungers stuck in or out, stuck valves that are frozen in place, bad internal windings, and excessive noise during operation. Some of these problems are the result of internal solenoid issues, while others are typically caused by external components. The solenoid troubleshooting process differs from one instance to another, as sometimes a faulty unit can be repaired, while others simply need to be replaced.
Solenoids are electromechanical devices typically used to regulate the flow of various substances. The basic structure of a solenoid typically consists of a helical coil wound around a steel or iron armature. When electrical energy is applied to the solenoid, it can be converted into mechanical energy in a predictable way. Solenoids are often coupled to valves and used to open or close them depending on whether or not an electrical signal has been applied. In other cases, the solenoids can be used to do other mechanical work, such as closing a series of contacts.
Due to the fact that solenoids depend on inductive coils to function, many common solenoid problems revolve around this system. Internal windings that have gone bad can cause a solenoid to stop working properly, and it’s possible for the coils to melt, burn, or simply short out. Similar problems can occur if the armature is bent or dirty, if there is excess heat or humidity, or if the wrong voltage is applied to a drive.
Many other common solenoid problems involve the valves that these components are often designed to open and close. Solenoid valves can be two, three or four-way and increase in complexity accordingly. If a solenoid doesn’t open or close properly, a common problem is dirt or other contaminants in the valve seat. This type of sand can cause a valve to block or prevent it from seating properly. Improper voltages can also cause this problem, as can corrosion and burnt coils.
Most solenoid problems cause a component to fail, although other problems simply create a nasty or annoying sound. Solenoids that buzz or make noise during operation usually do so due to the internal components of the valve. In most cases, these noises are caused by excessive fluid pressure differentials between the inlet and outlet sides of a valve. If this is the case, the noise can typically be reduced by taking measures to decrease the pressure on the inlet side.
