MVR process drawings
The following MVR process drawings are for reference only. According to the evaporation solute, the process is also different.
MVR roots steam compressor features
Shell: The inlet adopts spiral type. When the impeller rotates, the gas enters the shell through the spiral line to form a circular cavity, thus reducing the pulsation of the blower.
Material selection 304/316L/2205/HT200+Ni-P
Rotor: Three-leaf or two-leaf type, compound type line, Impeller area utilization factor 0.5, volume efficiency increases 5%, noise reduces about 5dB
Material selection 304/316L/2205/HT200+Ni-P
Wallboard: The surface is provided with a backflow groove. This structure can increase the compression ratio of the blower and can also help reduce the noise of the blower.
Material selection 304/316L/2205/HT200+Ni-P
Mechanical seal: Double-faced container-type mechanical seal, moving ring using silicon carbide or graphite, static ring using carbide steel, easy installation and maintenance, special design structure, use more reliable.
Bearings: Positioning bearings are NSK bearings that are imported from Japan.
Gears: High-precision grinding gears are used to reduce mechanical noise, and the accuracy reaches level 5 of the national standard GB/T10095-2008.
