MVR, an abbreviation for Mechanical Vapor Recompression, represents a groundbreaking energy-saving technology. This ingenious process significantly minimizes the need for external energy by ingeniously revamping the secondary steam energy it produces. The fundamental principle of MVR is as follows: secondary steam generated by the evaporator is expertly compressed using a state-of-the-art, high-efficiency steam compressor. This transformative process converts electrical energy into thermal energy, resulting in an increase in both pressure and temperature of the secondary steam. Once elevated, the secondary steam circles back to the evaporator to efficiently heat the materials, inducing further evaporation. This creates a virtuous cycle that maximizes the recycling of the secondary steam's latent heat of vaporization, leading to outstanding energy efficiency and sustainability.
The Oil-Film High-Speed Direct Drive Steam Compressor is a marvel of turbine engineering, powered by an ultra-efficient permanent magnet motor. At the heart of its design, the impeller is seamlessly mounted at the shaft extension end of the motor, ensuring peak performance. The rotor, elegantly supported by an oil film bearing, enables an unrivaled direct drive experience through the high-speed motor, eliminating the need for cumbersome speed increasing boxes and couplings. This advanced configuration promises superior efficiency and reliability, showcasing the cutting-edge technology and innovation behind this extraordinary compressor.
3.3.1 Begin by seamlessly placing the compressor base onto the foundation. Carefully utilize wedge-shaped shims beneath the base to meticulously adjust the unit to the ideal level.
Craft a precise leveling with alternating wedge-shaped irons, ensuring that every unit is perfectly aligned. Spot weld these irons securely at 4 to 5 points to maintain stability.
Remember, it's essential that the wedge is custom manufactured and installed by the user, tailored to the specific circumstances. The contact surface should be finely finished to guarantee a smooth, even contact.
Ensure the inclined plane is in balanced contact, with the wedge iron bearing no more than a robust 40Kg/cm2).
3.3.2 Employ a level to ascertain absolute precision. The unit's axial level must achieve a meticulous 0.05/1000mm, while the horizontal level should not exceed 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Perfect alignment of the coupling is crucial. Prioritize these essential checks before aligning:
1) Ensure the main power supply is completely turned off to avoid any risks;
2) Dismantle the coupling shield with care;
3) Remove the intermediate section of the diaphragm coupling;
4) Scrutinize the motor installation plane for absolute flatness, ensuring it's devoid of debris, dirt, or unwanted attachments;
5) Guarantee that motor bolt holes exceed the bolt size, allowing adjustments by loosening the bolts;
6) Have a sufficient supply of pristine stainless steel gaskets, ready to snugly fit beneath the motor feet—these must be free from any attachments and completely flat, avoiding the use of slender gaskets for adjustments;
7) Utilize a dial indicator or a precision laser alignment meter, boasting an impressive accuracy of 0.01mm, which should be prepared by the customer;
8) Prepare a sturdy bracket for the dial indicator support, as depicted in the accompanying illustration;
9) Employ the motor wheel hub mounting bracket to strategically position a dial indicator on the wheel hub's edge, ensuring the probe touches the compressor wheel hub's outer edge;
10) Skillfully adjust the bolts around the motor feet to align the compressor and motor center lines, maintaining a maximum outer circle deviation of just 0.05mm. The motor shaft center line must be slightly above the compressor's low-speed shaft center line, with coupling end face precision of 0.03~0.05mm;
11) Proceed to secure the motor foot bolts firmly, followed by a meticulous review of the outer circle runout and coupling end face runout.;
12) Conclude by installing the coupling's intermediate section post motor idling test, ensuring flawless operations.
3.3.4 Post adjustment of 'levelness' and alignment, firmly tighten the anchor bolts. After mechanical operations or test runs, it's imperative to loosen and retighten these bolts to ensure continued stability.
3.3.5 The impeller, a formidable high-speed rotating component, must be shielded from any solid or liquid intrusion to avert irreversible compressor damage. Ensure immaculate cleanliness of the pipelines connected to the compressor, matching the system's steam corrosion-grade requirements. For pipelines falling short, consider adding solid-liquid separation equipment, like a gas scrubber or sedimentation tee, before the compressor inlet's straight pipe to maintain integrity.
3.3.6 Now, skillfully install the compressor's inlet and outlet pipes. These pipelines must include all relevant accessories as depicted in the PI diagram. It's vital that such pipelines receive support from a separate bracket, as their weight should never burden the compressor body itself.
3.3.7 Once the main fan and its auxiliary equipment are fully installed and the concrete foundation properly cured, proceed to the exhilarating compressor operation test with confidence.
