  • Rotary Screw Compressor Winterizing Tips
    The oil flooded rotary screw is the most popular type of air compressor used by industrial plants. However, there is still a mystique about some aspects of this type of compressor. The company featured on our website at has repaired thousands of rotary screw airends. We wanted to gather ideas from
  • Vibration Readings On Compressor
    Vibration readings came into alarm on #6 Frick ammonia high stage compressor. Vibration readings taken on the outboard side of the male and female compressor screw bearings continued to rise. Readings went into alarm in April. Work order was written to repair compressor. Work was submitted
  • Regaining Control of Controls
    screw unit rated at 1685 CFM. The reciprocating compressor uses a 5 step regulator for control. The rotary screw compressor uses modulation/on line, off line with Automatic Control Selector. Controls were set to hold a minimum 95 psig system pressure. The average demand for compressed air
  • Power Plant Thermography - Part II
    in the control panel of a large. commercial chiller. This chiller utilizes four screw type compressors. A hot spot was identified on the main. power supply, "B" phase connection. The temperature on the main power supply lead can vary based on load. and compressor sequence. This compressor automatically
  • Compressors
    separators are needed to remove the oil from the air as it leaves the compressor. They are available over a power range of about 7 to 300 hp. Single-screw compressors are based on the same principle as helical compressors. As the central screw rotates, air trapped between the screw teeth
  • Smith & Nephew Orthopedics Reduces Unplanned Downtime by 90% With Help from IR
    STUDY-3: AIR COMPRESSOR MOTOR COUPLING. Figure 9 is a motor coupling on a 150 horsepower rotary screw air compressor, when the coupling was. disassembled the rubber inserts were badly worn. Figure 10 is a visual and figure 11 is the infrared image. after repair. Figure 9. Motor coupling on a 150
  • Want More Precise Assembly? Use Fewer Constraints
    . Screws snugged the compressor subassembly to the vessel flange at one end, resulting in a cantilevered load. A support on the opposite end of the subassembly, bolted through the wall of the vessel, alleviated the load and cut vibration. The support included an adjustable cylinder, a long screw
  • Want More Precise Assembly? Use Fewer Constraints
    ). The flexibility of the screw rod ensures parallelism between the seal screw and the vessel (deformation method). Despite these accommodations, human error and multiple constraints made it hard to seal the system. The design does not need precise assembly between the compressor subassembly
