DFSR-WN Industrial Steam Roots Air Compressor
MVR Roots Steam Compressor
Our company's MVR Industrial Steam Roots Air Compressors have been developed with air capacity from 5 m3/min to 130
m3/min. The maximum pressure difference between inlet and outlet is
58.8Kpa to 80Kpa.
Specific parameters are shown in the following table:
| Model | Air capacity (m3/min) | Differential pressure (Kpa) | Rotating speed (rpm) |
| DFSR-100WN | 5-9 | 58.8-80 | 1000-1650 |
| DFSR-125WN | 10-22 | 58.8-80 | 870-1650 |
| DFSR-150AWN | 20-30 | 58.8-80 | 980-1580 |
| DFSR-200BWN | 24-45 | 58.8-80 | 930-1550 |
| DFSR-250WN | 45-76 | 58.8-80 | 750-1250 |
| DFSR-300WN | 75-130 | 58.8-80 | 750-1250 |
Note:
1. The air capacity in the table is measured when the pressure
difference between the inlet and outlet is 40Kpa. The maximum
allowable pressure difference of the actual MVR compressor can be:
A- FSR-250WN, FSR-300WN, the maximum allowable differential
pressure is 60Kpa
B- FSR-100WN, FSR-125WN, FSRSR-200WN, FSRSR-250WN, the maximum
allowable differential pressure is 80Kpa.
2. In the table, rotating speed is the recommended value. Don't try
to exceed the range.
MVR steam recompression principle
MVR (mechanicak vapor recompression) is an abbreviation of
Mechanical Steam Recompression Technology. MVR uses the secondary
steam generated by the evaporation system and its energy to upgrade
the low-grade steam to the high-grade steam heat source through the
mechanical work of the steam compressor. An energy-saving
technology that provides heat energy to the evaporation system so
as to reduce the demand for external energy. In theory, the MVR
technology saves more than 80% of energy compared to traditional
evaporators, saves more than 90% of condensate, and reduces
footprint by more than 50%.

Common Problem Solution of FSR-WN Roots Steam Compressor
1. Corrosion
1) Optional SUS304, SUS316, SUS329 stainless steel. SUS304 and
SUS316 are used for relatively
small conditions of temperature rise. SUS329 stainless steel is
used for high temperature and
severe working conditions due to its small thermal expansion
coefficient and good corrosion
resistance.
2) Cast iron can be used to add Ni-P coating or Teflon coating. The
advantage is that the coefficient
of thermal expansion of cast iron is much lower than that of
stainless steel, which can effectively
prevent the rotor from being locked up during rotation.
2. Sealed form
Sealing forms include:
multiple labyrinth seals,
Double shaft seal (VITON oil seal prevents oil in the mailbox from
entering the side/main housing, Viton seal),
Air blowback seal,
Machinery Seal,
Such as, a variety of flexible forms of sealing combination, can
guarantee the compressor under positive pressure or negative
pressure working conditions, in water vapor or alcohol vapor and
other different media environment, the seal can be long-term
effective and reliable
3. Cavitation
1)The peripheral speed of the control rotor is 30 m/s lower than
the peripheral speed at which no cavitation occurs at present.
2) Adopt SUS329 stainless steel with good cavitation resistance.
3) The inlet of the Roots steam compressor is sprayed with an
appropriate amount of spray water to control the outlet
temperature.
