Industrial pressure switches | Pressure controls | Danfoss

Danfoss pressure switches are electromechanical controls and limiters that control the pressure of air and liquids within a given pressure range. All contact systems in Danfoss regulating units incorporate a "snap-action" system that maintains the contact force until the moment of contact break.

1997-2011 Corvette Fluids and Performance | CC Tech

Sep 22 2011 · 1997-2011 LS engines idle with 20-30PSI of oil pressure typically. On a hot day after the engine and drivetrain has warmed up it is possible to see 15PSI at idle without any concern. The main thing to watch for is a rise in pressure once in gear. At 2000 RPM you should see 45PSI.

Part 1 - National Board of Boiler and Pressure Vessel ...

Boilers are blown up every year as a result of poor atomization of oil which results in incomplete combustion and can lead to unburned oil puddling on the floor of the furnace. To prevent this the oil tips must be clean the oil temperature must be correct the oil viscosity must be in spec and the atomizing steam (or air) pressure and fuel ...

Boiler Fuel Oil Atomizers - Marine Engineering Study Materials

The fuel cup which rotates at 70 to 100 rev/second is supplied with oil at low pressure (1.7 to 4.5 bar) from the metering pump which is used to control the throughput. Due to centrifugal force and opposite swirl of air to fuel the oil film leaving the cup is rapidly broken down into relatively even sized droplets. Main features are: High output possible up to 3600 kg/h. Low oil supply pressure. At low throughputs
