MVR, or Mechanical Vapor Recompression, stands as a revolutionary energy-conserving marvel designed to significantly curtail the reliance on external energy sources. By ingeniously reutilizing the secondary steam energy it generates, this cutting-edge technology employs a high-efficiency steam compressor to transform electrical energy into thermal energy. Its fundamental principle revolves around compressing secondary steam produced by the evaporator, boosting its pressure and temperature. The elevated temperature and pressure enable the secondary steam to return to the evaporator, effectively heating materials and inducing further evaporation. This cycle ingeniously recycles the latent heat of vaporization of the secondary steam, showcasing an exceptional model of energy sustainability and efficiency.
The Oil-Film High-Speed Direct Drive Steam Compressor is a state-of-the-art turbine apparatus, deftly integrating a high-efficiency permanent magnet motor. In this remarkable design, the impeller is seamlessly mounted at the shaft's extension end of the motor. The innovative rotor is supported directly by an oil film bearing, enabling a sleek direct drive powered by a high-speed motor. Notably, this advanced system operates without the need for a speed-increasing gearbox or coupling, ensuring not only enhanced efficiency but also streamlined maintenance. This compressor epitomizes cutting-edge engineering, delivering unparalleled performance in steam compression technology.
3.3.1 Begin by seamlessly positioning the compressor base directly onto the foundation. Introduce wedge-shaped shims beneath the base, which are essential for fine-tuning and leveling the unit.
Carefully alternate the placement of two wedge-shaped irons ensuring optimal leveling of the unit. Securely spot weld the wedges at 4 to 5 strategic points for enhanced stability.
The fabrication and installation of the wedges should be customized by the user based on specific, real-world conditions, ensuring a uniformly finished contact surface.
The inclined plane should exhibit even contact, with the bearing capacity of the wedge iron meticulously restricted to not exceed 40Kg/cm2).
3.3.2 Utilize a precision level to ensure exactitude. The unit's leveling criteria demand an axial precision of 0.05/1000mm and a horizontal precision of 0.10/1000mm, ensuring flawless performance.
level of the unit is 0.10/1000mm.
3.3.3 Centering the coupling is paramount. Prior to initiating alignment, ensure the following vital prerequisites are fulfilled:
1) Cut off the main power supply to ensure safety;
2) Carefully remove the protective coupling shield;
3) Detach the diaphragm coupling's intermediate section with precision;
4) Inspect the flatness of the motor's installation surface, ensuring it is free from debris, dirt, and any unwanted attachments;
5) The motor's bolt holes must exceed the bolt size, allowing for loosening to adjust the motor's position seamlessly;
6) Amass ample, pristine stainless steel gaskets to support the motor base. These gaskets must remain impeccable, as elongated and thin gaskets are unsuitable for adjustments between the motor and its base;
7) Employ a dial indicator or a laser alignment meter with an impressive accuracy of 0.01mm, which should be provisioned by the customer;
8) Ensure availability of a sturdy bracket specifically designed to support the dial indicator as demonstrated in the illustration below;
9) The motor wheel hub mounting bracket should be adeptly used to affix a dial indicator on the wheel hub's edge, positioning the probe on the compressor wheel hub's outer edge;
10) Through strategic adjustment of the motor feet's bolts, align the compressor and motor center lines harmoniously, with a maximum deviation of 0.05mm. The motor shaft's center must stand slightly above the compressor's low-speed shaft, while the coupling's end face deviation should be between 0.03~0.05mm;
11) Conclude by securely tightening the motor foot bolts. Rigorously review the runout of both the outer circle and the coupling's end face to ensure precision.;
12) Following a successful motor idling test, proceed to reinstall the coupling's intermediate section with confidence.
3.3.4 After achieving impeccable 'levelness' and alignment, firmly tighten the anchor bolts. Post mechanical operation or trial run, release the bolts briefly and retighten them attentively.
3.3.5 The impeller, a high-speed rotating marvel, must remain free from foreign solids or liquids that could inflict irreversible damage. It is imperative to maintain pristine inlet and outlet pipelines, adhering to the system's steam corrosion standards. Rectify non-compliant pipelines immediately, and consider installing solid-liquid separation equipment such as a gas scrubber or sedimentation tee before the compressor's inlet.
3.3.6 Install the compressor's inlet and outlet pipes with precision. Adhere to the PI diagram for the installation of relevant pipeline accessories. Ensure the associated pipeline is independently braced, as its weight should not impinge upon the compressor's body.
3.3.7 Once the main fan and its supporting equipment are securely installed and the concrete has fully set, it's time to proceed with the thrilling operation test of the compressor. This marks a significant milestone in ensuring that all components function flawlessly together.
3.3.8 For optimal performance and safety, the compressor's electric control cabinet should be strategically positioned within 5 meters of the compressor itself. To maintain a sleek and secure setup, the wiring from the compressor to the electric control cabinet should be meticulously threaded through underground pipes. Once the electric control cabinet is properly installed, connect its wiring terminals seamlessly with the lines at the remote DCS, ensuring a robust and integrated system.
