Tech Tip: Hose Maintenance

Prevent premature washdown hose wear and failure. Washdown hoses are often subjected to physical abuse while in service. Select a hose that meets or exceeds the application it is intended for. Consider temperature, pressure, and environmental concerns such as abrasion and chemical resistance. Every plant should have a maintenance/inspection plan in place to ensure the longest possible life of the hose.

Be sure to consider these steps in your plan:

  • Store hose properly when not in use.  Hose racks or reels are highly recommended to keep hoses off the floor and out of harms way. Pay attention to humidity, temperature, ozone and sunlight. Storing out of direct sunlight, in a room with moderate humidity and a temperature range of 50 to 75°F is recommended.
  • Always shut off the water supply to the hose when not in use and open the nozzle to relieve the pressure before storing.  Leaving water in the hose subjects it to constant pressure and will shorten the life of the hose.
  • Don’t pull the hose by the nozzle – this puts undo stress on the connection point.
  • Avoid exceeding the hose’s rated bend radius. Kinking of the hose can create weak spots in the hose wall. Consider using hoses with internal springs or kink guards to prevent kinking directly behind the coupler.
  • Never exceed the rated temperature and working pressure of a hose assembly.
  • Routinely inspect hose for wear and damage. Look for external damage – stiffness, discoloration, cuts, cracks, kinks, blisters, excessive abrasion and exposed or broken wires.
  • Regularly inspect fittings.  A hose should be removed from service if any fitting movement or damage is found that could prevent it from operating as intended.

Giving careful consideration to hose selection, care, maintenance and storage can provide optimum return on your investment. For more information contact our Process & Flow Control department at 800-826-8302.

Product Focus: Nilfisk Vacuums, Explosion-Proof Industrial Safety

D07F8194While sitting and reading this, you can probably look around and find something dusty. Maybe it is the top of your screen or the top of your keyboard. Dust can be annoying. Dusting is a necessary annoyance. It may be hard to think of it as a critical hazard, though. However, “dust” takes on a whole new meaning when it comes to plant maintenance. If you are one of the 30,000 U.S facilities at risk for combustible dust explosions, dust may be a significant threat to your employees and your operation.

According to Nilfisk Industrial Vacuums, “Regardless of industry or material, combustible dust can be formed from milling, sanding, grinding, crushing, cutting – or simply handling product in powder form.” One might not realize the potential danger combustible dusts possess and or even what exactly is considered “combustible.”  For example, grain dust, perhaps a harmless sounding material to the layman, is “nine times as explosive as coal dust.” Such insights should cause us all in the food industry to step back and think about the safety of our employees, our operations, and the materials that surround us. Unfortunately, the threat extends beyond explosions, too. In fact, dust can cause fires as well, which are “the most common dust-related incidents.”

If you are curious or want to know more about combustible dust explosions and precautions used to prevent such occurrences click here.

Presently, Nilfisk and Nelson-Jameson, Inc. are working together to bring you a line of vacuums to combat this threat. Nilfisk’s line of Explosion-Proof Electric and Pneumatic Vacuums are built to take on combustible dust, helping to improve sanitation and assisting in complying with OSHA standards.  You can see these two lines of vacuums and numerous other Nilfisk vacuums and accessories in this catalog. Nelson-Jameson product managers can also assist you in finding the right vacuum and accessories for your facility. Give us a call today at 1-800-826-8302 to order or for more info.

Tech Tip: Preventive Maintenance for Insect Electrocutors

FlySetting up a Preventive Maintenance Program for your insect electrocutors is the best way to ensure that your units are working to their full potential. Ideally, you would choose a month each year for your PM program to be done on the units. It is suggested that this is in the beginning of the year or Spring, with a new insect season.

The PM program should include checking the bulbs for their effectiveness, and making sure there are no other issues with the unit. Fluorescent bulbs that are used in insect electrocutors have an effective life span of 7000 hours or about 9 months. For your convenience, all of our Shat-R-Shield® or Insect-O-Cutor® bulbs come with year labels on them. This aids in your PM program as you are able to tell from a distance what year is labeled on the bulb, and whether it is time to be changed.

Even though a bulb may still be lit, does not mean it is attracting insects, so changing out yearly is recommended. For more information, visit our Learning Center.
