2 Stroke Troubleshooting

Troubleshooting a pneumatic system has been considered an art, science, or just hit-or-miss opportunity. In the spirit of maintenance personnel, production managers and plant managers, troubleshooting word conjures up images of hours of downtime and lost production.

However, when reduced to its basic components, troubleshooting a pneumatic system is a step-by-step. Through this process accelerates the ability to determine what is the problem, the probable cause of the malfunction or failure, and a solution.

Each pneumatic system has a logical sequence of operations that may involve the detection logic synchronization of pressure, position detection, and speed control. Troubleshooting is launched when the system is not working properly.

Some general steps and diagnostic tests can be applied to any problem troubleshooting if the problem occurred when starting a new system or a failure of an existing system.

Think Safety First
Safety should always be a major concern for the personal interview. The compressed air is a volatile element in a pneumatic circuit. compressed air tanks exploded, causing serious injury to personnel and damage to property. It is imperative to relieve the pressure in a receiver tank before repairs.

The air is also very compressible, which is another reason for caution in approaching the resolution of a pneumatic system. When working with overhead costs that are supported by rollers, but not mechanically locked into position to block the charge before the maintenance system to prevent falling or drifting.

Many pneumatic systems are controlled by electrical or electronic. Before attempting to service or repair of these components, make sure the power was turned off.

Pneumatic directional control valves that use electric solenoids to operate the drawer are often equipped with manual controls (Fig. 1) which can be used during troubleshooting to make the system work.

pneumatic valve lockout (Fig. 2) are excellent safety devices, if properly used on pneumatic systems, may prevent accidental operation. Ensuring a safe state should always be the first step in troubleshooting pneumatic systems.

Ask three was
When a system failure occurs, the pressures of downtime prominently in the minds of all concerned. Before beginning a repair system, stop and ask these three questions:

What is or is not occurring in the operation of the system?

When did the problem begin? Was it a sudden failure or progressive failure?

Where in the cycle of the machine the problem occurs? Was this the start or after the system has worked for a while?

What is or is not occurring within the system can often be answered by the network manager. The answers to questions such as the slow speed actuator or the inability of the actuator to move the research could lead to a low flow or low pressure.

Asking, "When did the problem begin? can often lead to troubleshooting steps to find worn or leaking. sudden failures may point to breaks and possible mechanical problems, line breaks, or other catastrophic failures. In determining the time, the research problem can be reduced in scope.

By asking "Where in the cycle of the machine the problem occurs? may be a recurring condition.

While good maintenance records were kept, the recurring problems should have been recorded. This information makes the troubleshooting process much easier.

A maintenance worker who was asked for three stops and can reduce downtime does not have to guess what is wrong. However, if these issues do not give a satisfactory diagnosis the maintenance person must begin the process of solving problems by visual inspection of the machine.
