THE 6 STEPS TO SOLVE THE START-UP PROBLEM
My air motor has a problem when starting. However, as soon as the engine is running, the problem disappears. What is the solution?
THE 6 STEPS TO SOLVE PROBLEMS
IS THE ENGINE SUITABLE FOR YOUR APPLICATION?
If the motor is used 24 hours non-stop, we recommend a turbine motor or a gear motor for these applications.
A vane air motor is generally more suitable for regular and interrupted cycles.
What kind of environment is the air motor exposed to?
BASIC LINE Air motors are used in dry standard production environments.
ADVANCED LINE Air motors with stainless steel housing are sealed and can therefore operate in extreme environments such as steam and dust. Our ADVANCED LINE motors are specifically adapted for different applications. For use in salt water, the housing materials and seals are specifically designed. Motors created for the food industry can be manufactured with a cleaning-resistant housing. In the medical industry, specific vane material can be used that will withstand the sterilization process.
WHAT AIR QUALITY IS USED?
The supply air must be dry and free of dirt particles. Dust, condensation or foreign particles in the air can damage the air motor gearing. Optimum durability and maximum performance of the air motor is obtained if you lubricate the motor without oil, resin or acid. One or two drops of oil per cubic meter of compressed air is all that is needed. Too much oil can result in loss of performance.
DEPRAG air motors of the Basic Line and Advanced Line are also suitable for oil-free operation.
The result should be taken into account in a power penalty of approximately 15%.
DO THEY SUPPLY A SUFFICIENT VOLUME OF AIR?
Are there any constructions (valves, fittings, connectors) that throttle air supply or air exhaust?
Do you use hoses that have a sufficient internal diameter, are no longer than 3 meters and do not kink? Every additional meter between the compressor and the air motor causes a loss of pressure and, consequently, reduces the performance of the motor.
DO THEY SUPPLY SUFFICIENT AIR PRESSURE?
Often, there is sufficient pressure at the compressor, however, it does not reach the air motor. Measure the air pressure directly at the motor air inlet. Is the available pressure sufficient for your application?
WAS THE AIR MOTOR SERVICED AT REGULAR INTERVALS?
How long (how many cycles) was the motor in operation?
How often an air motor should be serviced depends on many different factors. The duty cycle, application environment and conditions of use are just as important as the gear size and torque load that a motor must handle.
TECHNICAL TROUBLESHOOTING POSSIBILITIES TO HELP WITH AIR MOTOR STARTING BEHAVIOR
Functionality test: Can you hear air flowing through the engine, even though the engine will not start?
If this is the case, then the problem may be that the pallets cannot be moved outward or that no working chambers have been created.
If the motor does not have to start against a load, then the integration of spring-loaded vanes can drastically improve the starting performance of the motor.
If the problem is still not resolved, then our Application Experts will gladly help you find a solution through corrective actions.
