On today’s market, you have a choice of two main types of industrial rotary compressor – vane and screw. Although both are designed to produce the same output, they differ considerably in terms of energy efficiency. Here, we give you the low down. .
How they work – A rotary-vane compressorcomprises a rotor, with slots along its sides which house individual sliding vanes. This assembly is offset within a cylinder, or ‘stator’, and rotates on white-metal bushes. As the rotor turns on its axis, the vanes. .
Vane compressors typically run at lower speeds than relatively leaky screw machines. For example, Mattei’s fixed-speed Maximaoperates at 1,000rpm, versus the average screw compressor’s 3,000rpm or higher. Rotary-vane machines also have. .
How they work– A screw compressor has two parallel rotors which intersect along their sides. Replaceable roller bearings fitted into a stator maintain the rotors’ minimum clearance. During rotation, the intermeshing rotors compress the air. Their efficiency–.

This is job No. 1. It doesn’t matter how regular you are about maintenance if the person handling the tools doesn’t know what he’s doing. Says Caho: “You need someone who’s actually trained to do it.” From what Caho has seen, that’s easier said than done these days. “One of the bigger problems is that a lot of. .
If you’re maintaining your rig properly, this should be a regular part of your routine. “Those should be checked every day, or even throughout the. .
A checklist creates a sense of organization and accountability on the jobsite. “I’m a big believer in a daily inspection form that has been made up by the company,” Caho admits. “Almost. .
This has become an increasingly important factor in rig maintenance. “Make sure you’re using the specific fluids that the manufacturer or your company has required,” Caho. .
There’s a tendency to take shortcuts when it comes to wearing safety gear. Don’t do it. Personal protective equipment can’t be viewed as an option. You always want to be dressed in a way.
