Pneumatic Valves, Motors And Fittings
It is not only important to purchase the best pneumatic system of valves, motors, cylinders and fittings, but to keep it maintained in good operating order. One needs to buy the best system possible and then hire highly qualified personnel to maintain it. If a second rate system is purchased or improper maintenance is done, lost manufacturing and work time can result. System failure can even result in worker injuries, so it is important to do everything right from the purchase onward.
Though the very term pneumatic system sounds like high maintenance and complications, that does not have to be the case. Purchasing a good system from a reputable supplier is the first step. Look around at a few systems from different manufacturers to see which one best meets your manufacturing needs and budget. Getting a good system built for low maintenance and longevity is a good start. Making sure you have a well trained, dedicated crew to operate and maintain the system is the next step. You will need maintenance personnel, plant managers and production managers who are familiar with your new system and qualified to trouble shoot it when something goes wrong.
Pneumatic valves systems have a logical sequence designed in that can include timing logic, position and pressure sensing,and speed regulation among other functions. Your system will have valves, fittings, cylinders and motors to maintain. Each system is designed for the particular job it is doing and so has it's own personality and uniqueness to be taken into consideration. Compressed air is one volatile part of a pneumatic valves system that can cause tanks to explode and damage property and injure workers.Before any work is done, that air pressure needs to be relieved or lessened. Electricity often runs the system and needs to be considered during repair and maintenance procedures.
When a pneumatic system is not working, the repair engineer should shut down the system and take pre repair steps for safety. Electrical power should be off, pneumatic manual overrides should be ready to use, pneumatic lockout valves should be engaged. Before proceeding, the cause of trouble should be found by considering these factors--What is not happening in the system that should be?, When did the trouble start? Was it sudden, or over a period of time?, Where in the system do things start to go wrong? Did the problem start right after start up of system or later in the process? If good records of maintenance have been kept, that could help pin point when the problem started. Walking around the system taking note of it's condition could help locate the problem. Reading the system's schematics and maintenance manual will be essential at this point.
The repair team should make a list of problem areas and probable causes for the problem. Tests of the system might be necessary. Some of these are checking actuator alignment, flow rate, temperature of the air system. When a complete list and tests are completed the team should try the least invasive and expensive things first, like adding lubricant or adjusting the drip rate. If something serious has gone wrong it will be time to decide whether to repair the system or replace it with a better one.
