Exploring The Different Types of Industrial Machinery Hello, I am Jeff Blackwell. Welcome to my website. I am here to talk to you all about the different types of machinery used in industrial settings. The machinery used for industrial operations are usually purpose built and expertly maintained. By purpose building the equipment, industrial operations can be completed to spec without any delays. On this site, I will explore all of the different equipment types used to complete every industrial process. I hope to inspire you to learn all you can about industrial equipment.

Hydraulics work because liquid is not compressible. As fluid is forced into a tube it exerts enough force to move a piece of the machine. Pumps are used to push the fluid into the correct tube to move the correct part. If you have a problem with the fluid pump, your hydraulics are not going to work efficiently. They may not work at all. Here are a few tips to help you troubleshoot fluid pumps.

Increased Operating Noise

If you notice that your machine is louder than normal, perhaps at a higher pitch, it may be due to the pump not being able to draw in enough oil before it pumps it out. This will result in slower hydraulic movements or the parts may not move as much. You should check and clean strainer between the fluid reservoir and the pump. While doing this, make sure there is not kink or tiny hole in the tubing. Once you have fixed a hole or kink, and cleaned out the strainer, your machine should be working quieter and better.

Strange Noises

When you hear noises that are not just normal operating sounds, it could be there is air trapped in the system. This can result in jerky movements. The quickest way to tell if this is the problem is to check the fluid in the reservoir immediately after shutting down the machine. If the fluid is milky in color, you either have air or water in it. If it is air, the fluid will clear once it cools down. Check it again in about an hour. The first thing to do is to bleed the lines. Make sure all the air is out and then run the machine again. If it starts to jerk about again, there is a leak somewhere. Check all gaskets and seals to see if the air is getting in around them. If necessary, replace them. If you cannot locate the leak, you may need to have a professional come take care of the problem.

Keep in mind that a machine that is not operating correctly can cause damage and injuries. You may not think having the arm jerk around a bit or not extend properly is a big deal, but if someone gets in the way it can be. Getting in the way is much easier when the normal path of the arm has changed because of a malfunction. If you cannot fix the problem yourself, hire someone who can as soon as possible to keep everyone and thing safe. Contact a company, like Compressor-Pump & Service, Inc., for more help.
