MVR, an abbreviation for Mechanical Vapor Recompression, represents a cutting-edge energy conservation technology designed to dramatically reduce reliance on external energy sources by harnessing and repurposing secondary steam energy produced in the process. The innovative principle behind MVR lies in its ability to compress secondary steam generated by the evaporator using a high-efficiency steam compressor. This process ingeniously transforms electrical energy into thermal energy, elevating both the pressure and temperature of the secondary steam. The heated secondary steam is then circulated back to the evaporator, where it efficiently heats materials to induce evaporation, thereby achieving a remarkable recycling of vaporization's latent heat. This smart reuse of energy resources not only boosts operational efficiency but also significantly contributes to sustainability.
The Oil-Film High-Speed Direct Drive Steam Compressor stands as a pinnacle of turbine technology, incorporating a highly efficient permanent magnet motor. Its standout feature is its sophisticated structure, where the impeller is seamlessly mounted at the motor's shaft extension end. The rotor finds robust support through an oil film bearing, facilitating direct drive operation by the high-speed motor itself. This advanced design eliminates the need for cumbersome speed-increasing gears and couplings, leading to a streamlined, efficient, and low-maintenance system. This state-of-the-art compressor not only enhances performance but also offers an optimized solution for modern steam compression needs.
3.3.1 Begin with elegantly positioning the compressor base seamlessly on the foundation. Utilize wedge-shaped shims beneath the base to fine-tune the unit level.
Skillfully alternate two wedge-shaped irons and, once impeccably leveled, spot weld these at 4~5 strategic points. The wedge shall be
crafted and installed by the user, tailored to the specific scenario, ensuring a flawlessly finished contact surface (guaranteeing even interaction
with the inclined plane). The wedge's robust bearing capacity should not exceed 40Kg/cm2).
3.3.2 Employ a precision level to ascertain flawless alignment. The unit's leveling criteria are stringent: an axial level of 0.05/1000mm, and a
horizontal level of 0.10/1000mm, ensuring impeccable balance.
3.3.3 Achieve optimal coupling alignment. Prior to commencing alignment, ensure the following prerequisites are met:
1) Deactivate the main power supply, stabilizing the environment;
2) Carefully remove the coupling shield, clearing the path;
3) Detach the diaphragm coupling's intermediate section, facilitating access;
4) Meticulously inspect the motor installation plane for flatness, ensuring it's free of debris and contaminants;
5) Ensure the motor's bolt hole exceeds the bolt size, allowing bolt relaxation for motor adjustments;
6) Arm yourself with sufficient stainless steel gaskets to robustly support the motor's foot. Avoid long, narrow gaskets between motor and base;
7) Utilize a dial indicator or laser alignment meter, boasting an impressive precision of 0.01mm (customer's provision);
8) Be equipped with the specified bracket for dial indicator support as depicted in the subsequent illustration;
9) Employ the motor wheel hub mounting bracket to strategically position a dial indicator on the wheel hub's edge, and place the probe on the compressor wheel hub's outer edge;
10) By skillfully adjusting the motor feet's bolts, align the compressor and motor center lines with precision (or follow the corresponding directives), maintaining a max deviation of 0.05mm, ensuring the motor shaft center is elevated above the compressor's low-speed shaft center. The coupling end face deviation should be 0.03~0.05mm;
11) Securely fasten the motor foot bolts, then meticulously review both the outer circle runout and coupling end face runout;
12) Reinstall the coupling intermediate section post the motor idling test, ensuring all is in order.
3.3.4 After perfecting the 'levelness' and alignment of the casing, diligently tighten the anchor bolts. Post mechanical operation or trial, loosen and retighten them to ensure utmost stability.
3.3.5 The impeller, a high-speed marvel, must remain free of any solid or liquid ingress that could inflict irreparable harm. Thus, verify the cleanliness and compliance of inlet and outlet pipelines with system steam corrosion standards. Non-compliant pipes must be rectified, with solid-liquid separation equipment like gas scrubbers or sedimentation tees recommended before the compressor inlet's straight pipe.
3.3.6 Proceed to connect the compressor's inlet and outlet pipes. Install related pipeline accessories per the PI diagram. The pipeline connecting to the compressor must be supported by a separate bracket, ensuring no undue weight burden on the compressor body.
3.3.7 Once the main fan and its supporting equipment have been meticulously installed and the concrete has achieved full solidity, you are ready to commence the operational testing of the compressor. This crucial step ensures that your Efficient High-Speed Oil-Film Steam Compressor with Direct Drive Technology is prepared for optimal performance.
3.3.8 For seamless integration, the compressor's electric control cabinet should be strategically positioned within a 5-meter proximity to the compressor itself. The wiring between the compressor and this cabinet must be carefully routed using threading pipes that run underground. After securely setting the control cabinet, proceed to connect the wiring terminals within it to the lines at the remote DCS, ensuring a reliable and efficient communication pathway.
