MVR, which stands for Mechanical Vapor Recompression, represents a cutting-edge energy-saving technology designed to significantly reduce the need for external energy sources. This is achieved by ingeniously reusing the secondary steam energy it generates. The fundamental principle behind this technology involves compressing the secondary steam produced by the evaporator using a highly efficient steam compressor. This process transforms electrical energy into thermal energy, resulting in increased pressure and temperature of the secondary steam. The elevated temperature and pressure return the secondary steam to the evaporator, where it heats the materials and induces evaporation. This not only maximizes energy efficiency but also allows for the recycling of the latent heat of vaporization found in secondary steam.
The Oil-Film High-Speed Direct Drive Steam Compressor is an advanced piece of turbine equipment, meticulously engineered with a high-efficiency permanent magnet motor. The ingenious design features an impeller that is directly installed at the shaft extension end of the motor. The rotor is skillfully supported by an oil film bearing, facilitating direct drive by the high-speed motor. This innovative configuration eliminates the need for a speed-increasing box and coupling, offering a streamlined and efficient solution for industrial applications.
3.3.1 Begin your installation by placing the sophisticated compressor base securely onto the prepared foundation. Insert wedge-shaped shims beneath the base to ensure the unit is perfectly level. This meticulous step is crucial for optimal performance.
Place the wedge-shaped irons in an alternating pattern. Once you've achieved the desired level, proceed with spot welding the irons at 4 to 5 strategic points for enhanced stability.
These wedges, crafted by the user to fit the specific installation environment, must have an immaculate contact surface ensuring even contact across the inclined planes.
The capacity of the wedge iron should not exceed a robust 40Kg/cm2). This ensures long-lasting durability and performance.
3.3.2 Using a precision level, ensure the compressor is perfectly aligned. The axial level tolerance is a precise 0.05/1000mm, while the horizontal level tolerance is 0.10/1000mm, ensuring high operational efficiency.
Adhering to these stringent levels guarantees the smooth functioning and longevity of your compressor.
3.3.3 Centering the coupling is paramount. Prior to commencing alignment, please confirm the following preparatory steps:
1) Ensure the main power supply is turned off for safety.
2) Detach the coupling shield to access the interior components.
3) Carefully remove the diaphragm coupling intermediate section.
4) Inspect the motor installation plane meticulously, ensuring it is free of any debris, dirt, or unwanted substances.
5) Ensure the motor bolt holes are appropriately sized, offering the flexibility needed to adjust motor positioning when necessary.
6) Prepare a sufficient number of stainless steel gaskets for motor support. These should be pristine and flat, ensuring no attachments interfere. Avoid using elongated or thin gaskets for adjustments between motor and base.
7) Utilize a highly accurate dial indicator or laser alignment meter, boasting a precision of 0.01mm, which customers need to provide.
8) Prepare a robust bracket to support the dial indicator, as illustrated in the accompanying figure.
9) Use the motor wheel hub mounting bracket to securely affix the dial indicator to the wheel hub's edge, with the probe placed on the outer edge of the compressor wheel hub.
10) Fine-tune the adjustment bolts around the motor feet to ensure the compressor and motor center lines are perfectly aligned. The maximum permissible deviation of the outer circle is 0.05mm, with the motor shaft center line slightly elevated above the compressor's low-speed shaft center line. Coupling end face deviation should remain within 0.03~0.05mm.
11) Securely tighten the motor foot bolts, ensuring a final review of the coupling's outer circle and end face runout is conducted for precision.;
12) Reinstall the coupling intermediate section following a successful motor idling test, completing the alignment process.
3.3.4 Once the meticulous 'levelness' and alignment of the casing have been adjusted, proceed to tighten the anchor bolts. Post mechanical operation or trial run, it is advisable to loosen and retighten these bolts to ensure enduring stability.
3.3.5 The compressor's impeller, a high-speed rotating marvel, requires the utmost care. To prevent irreversible damage, ensure all inlet and outlet pipelines connecting to the compressor are pristine and adhere to the system's steam corrosion grade requirements. If discrepancies are found, pipelines must be rectified. Consider incorporating solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the compressor inlet's straight pipe section.
3.3.6 Proceed with the installation of compressor inlet and outlet pipes. Ensure import and export pipelines are equipped with necessary pipeline accessories as depicted in the PI diagram. The pipelines affiliated with the compressor should be independently supported by an additional bracket, preventing any undue weight from bearing on the compressor body.
3.3.7 Once the main fan, along with its ancillary equipment, is expertly installed and the concrete foundation has achieved complete solidification, you may proceed with the compressor's operational testing. This marks a significant step towards ensuring the reliability and performance of your High-Speed Oil-Film Compressor with Direct Drive, meticulously crafted by NANTONG DART-RICH FAN CO., LTD, for premium industrial solutions.
3.3.8 For optimal performance and seamless integration, the electric control cabinet of the compressor must be strategically installed within a 5-meter radius of the unit. The wiring, designed for durability and efficiency, should be threaded through an underground conduit linking the compressor to the control cabinet. Upon installation, ensure that the wiring terminals within the electric control cabinet are flawlessly connected with the remote DCS lines, facilitating robust and enduring connectivity for your state-of-the-art High-Speed Oil-Film Compressor with Direct Drive from NANTONG DART-RICH FAN CO., LTD.
