If you have just set up a pneumatic sand-conveying system, it should run seamlessly for quite some time. However, in order for it to continue to run effectively, you need to make sure that you take care of routine maintenance issues in order to continue running your pneumatic sand conveying system at a constant rate.

#1 Remove Debris From The Sand Feed Bin

You need to make sure that you occasionally check the sand feed bin; this feed bin should be located down below the blow tank. The purpose of the sand feed bin is to allow the sand to flow into the system via the use of gravity. You are going to want to check the inlet screen and remove it every few months to clear away any debris that may have accumulated on it. The accumulation of debris will prevent the free flow of sand into the system.

#2 Check The Compressed Air Machine

A compressed air machine should be attached to your pneumatic sand-conveying system. It is important that moisture and oil don't get into your compressed air machine in order to ensure that the sand flows correctly.

You are going to need to make sure that you take care of your compressed air machine. You are going to want to check the oil levels every few months. You should check and make sure that all the switches work every few months as well, such as the pressure gauge, temperature switches, overload relief valve, and differential switches. It is important that you keep the air filter clean as well to keep particles out of your pneumatic source system.

Keeping your air pressure systems running smoothly will help ensure that your overall system works correctly.

#3 Visually Inspect The Pipe Run

Make sure that you visually inspect the pipe run from time to time. You are going to want to look for and make sure that there are not any leaks in the pipe run where sand is coming out of the system. This will interfere with the overall flow of your system.

Also, make sure that you check the support on the pipe run. Make sure that the supporting structure is firmly connected to the ground and that it is capable of absorbing all loads and vibrations while it is operating.

#4 Check Opening & Closing Of Diverted Pinch Valves

If you have diverted pinch valves for multiple bins, you are going to need to check and make sure that they are opening and closing properly. To do this, just watch the pinch valves while they are being operated. Make sure that the pressure gauges are providing the right level of air to open and close the valves. If the pressure is not maintained, you may need to fix a worn valve.

Pneumatic conveyor systems need to be maintained regularly so you can keep up with peak performance.
