[pdf] The most common modes of shipping for drill rigs are air, sea, and land. Air shipping is the fastest mode of transport and is frequently used when time is of the essence. However, it is also the most expensive option. Sea shipping is the most cost-effective option, but it is also the slowest option.
[pdf] The air below the deck is typically hot, humid and saline. It’s not a friendly environment, and your compressor’s build quality needs to reflect this. The process starts with the compressor sucking in air from the surroundings. It enters the air end, which houses the screws. Oil is injected, acting as a lubricant. .
The screws push the air into an oil separator receiver. This unit consists of two stages: 1. High-efficiency cyclone separator 2. Oil. .
Having passed through the filter, the air is ready for some cooling. The non-return discharge valve, which only opens at a minimum positive pressure, lets the air through in appropriate measures. To cool down the compressed air to a level that will be acceptable for. .
A marine air compressor needs a proper water separator. By proper, we mean a cyclone separator with level-controlled drainage. The conventional approach is to use a solenoid valve on a timer. It opens up on regular intervals, causing pressure from the compressor.
