Rotary vane compressor

MAPRO® rotary vane compressors are positive-displacement machines. That is, the compression takes place for progressive reduction, inside the machine body, during rotation, of the gas volume mechanically displaced from the suction to the discharge port. The discharge port is opened, on the internal cylindrical surface of the stator, at an height depending on the foreseen discharge pressure, so that only the power needed for the actual compression of the gas is used. It follows that the adiabatic compression efficiency is always high, and, in general, between the 70 and the 80%. The tight internal clearances allow, as well, a high volumetric efficiency, basically unchangeable as blades wear is self-compensating in time. The power needed for the compression is therefore, in general, lower than that required from other types of compressors, with consequent lower operating costs. Simple and economic maintenance The small number of parts in motion simplifies the compressor disassembly and reassembly, so making these operations well less expensive than compared to other types of positive displacement machines. A specially provided control rod, allows a quick evaluation, at fixed time intervals, of the blades wear, without disassembling, even partially, the machine body so as to enter the compression chamber. It is therefore possible to plan the blade replacement largely in advance, according to the working planning of the plant or to the maintenance needs of other equipments, so simplifying the plant operation and improving its efficiency and economy.
