MVR, which stands for Mechanical Vapor Recompression, represents an innovative and energy-conserving technology designed to significantly reduce the need for external energy sources. It achieves this by masterfully harnessing and reusing the secondary steam energy it produces. The core principle revolves around compressing the secondary steam generated by the evaporator using a high-efficiency steam compressor. This process ingeniously transforms electrical energy into thermal energy, resulting in an impressive increase in both the pressure and temperature of the secondary steam. The elevated temperature of this steam is then redirected back to the evaporator, where it effectively heats the materials and induces evaporation, thereby facilitating the recycling of the latent heat of vaporization from the secondary steam. This not only optimizes energy use but also enhances operational efficiency, setting a new standard in sustainable technology.
The DM series Single-stage Geared Steam Compressor is an engineering marvel that encompasses a robust compressor body, an efficient coupling mechanism, a high-performance gearbox, a sophisticated lubrication system, a powerful motor, and an advanced electric instrument along with a state-of-the-art anti-surge control system. This cutting-edge compressor boasts a compact structure, meticulously designed for ease of maintenance. Its innovative design ensures seamless integration into various operations, making it a quintessential component for those seeking reliability and efficiency in steam compression technology.
3.3.1 Position the compressor base seamlessly on its designated foundation. Carefully place wedge-shaped shims beneath the base to achieve perfect leveling of the unit.
Alternately position two wedge-shaped irons, ensuring the unit is precisely leveled. Secure the wedges by spot welding at 4 to 5 key points for stability.
Manufacture and install the wedges based on the unique aspects of your setup, ensuring a smooth, even contact surface.
The contact plane must be inclined evenly, and the load capacity of each wedge iron should not surpass 40Kg/cm2). Follow these guidelines to ensure a stable and secure installation.
3.3.2 Use precision tools, like a level, to attain impeccable accuracy. The unit's axial alignment should be 0.05/1000mm, while the horizontal alignment must reach 0.10/1000mm.
3.3.3 Achieve perfect coupling alignment. Ensure all prerequisites are met before initiating the alignment:
1) Disconnect the main power to ensure safety;
2) Detach the coupling shield carefully for full access;
3) Remove the diaphragm coupling's intermediate section with precision;
4) Verify the motor installation plane's flatness, ensuring it's free of debris or obstructions;
5) Ensure the motor's bolt holes exceed the bolt size for easy adjustment and alignment.
6) Equip yourself with ample stainless steel gaskets to provide full support to the motor's foot, ensuring no attachments or irregularities.
7) Utilize tools like a dial indicator or a highly accurate laser alignment meter, both self-provided, for precision measurements.
8) Prepare the specified bracket to securely hold and position the dial indicator as depicted below.
9) Mount a dial indicator on the motor wheel hub bracket, strategically placing the probe on the compressor wheel hub edge.
10) Through meticulous adjustment of bolts surrounding the motor feet, align the compressor and motor center line perfectly.
11) Firmly secure the motor foot bolts and re-evaluate the alignment for both the outer circle and end face.Check for any deviations and correct as necessary.
12) Post motor idling test, reinstall the coupling's intermediate section to finalize the setup.
3.3.4 After achieving the desired 'levelness' and alignment, firmly tighten the anchor bolts. Post-trial operation, revisit the bolts for a secondary tightening.
3.3.5 The impeller boasts high-speed rotation; thus, any intruding solids or liquids can cause lasting harm to the compressor. Ensure all pipelines connected to the compressor are pristine and compliant with the steam corrosion standards.Implement solid-liquid separation devices, like a gas scrubber or sedimentation tee, prior to the compressor inlet to safeguard system integrity.
3.3.6 Securely install both the inlet and outlet pipelines, ensuring they are equipped with appropriate accessories as outlined in the PI diagram.
3.3.7 Once the installation of the main fan and all of its auxiliary equipment is completed and the concrete has fully set, you are ready to proceed with the compressor operation test. At this stage, the Energy-Saving Power Frequency Compressor, designed specifically for sugar liquid applications by NANTONG DART-RICH FAN CO.,LTD, is prepared to showcase its efficiency.
3.3.8 The electric control cabinet for the compressor must be strategically positioned within a 5-meter radius of the compressor itself. To ensure safety and durability, the wiring from the compressor to the electric control cabinet should be carefully encased in a threading pipe and routed underground. Once the electric control cabinet is securely in place, meticulously connect the wiring terminals within the cabinet to the lines at the remote DCS. This setup ensures optimal performance of the Energy-Saving Power Frequency Compressor from NANTONG DART-RICH FAN CO.,LTD.
