MVR, known as mechanical vapor recompression, is a groundbreaking energy conservation technique that significantly minimizes the reliance on external energy. It brilliantly achieves this by recycling the secondary steam energy it produces. The core essence of this technology lies in compressing the evaporator's secondary steam using a highly efficient steam compressor. This process masterfully transforms electrical energy into thermal energy, resulting in an increase in both pressure and temperature of the secondary steam. The elevated temperature and pressure enable the steam to return to the evaporator, where it effectively heats the materials and generates further evaporation. This intelligent cycle ensures the latent heat of vaporization of the secondary steam is thoroughly recycled, offering a truly sustainable solution.
The DML series low temperature rise steam compressor is ingeniously designed with state-of-the-art components to optimize performance. Its core structure includes a meticulously engineered compressor body, featuring intricate elements such as the volute, impeller, main shaft, bearing housing, and seal. Additionally, it incorporates a coupling, motor, and advanced electric instruments, all working harmoniously to deliver exceptional efficiency and reliability in steam compression.
3.3.1 The compressor base is meticulously positioned on the foundation. Place these precision-engineered wedge-shaped shims beneath to perfect the unit's level.
Position the wedge-shaped irons in an alternating pattern. Once the unit achieves level perfection, secure the wedges with spot welding at 4 to 5 strategic points.
Crafted and installed by the user to meet their unique needs, these wedges offer exceptional contact surfaces, ensuring seamless and sturdy support.
With a maximum bearing load of 40Kg/cm2).
3.3.2 Utilize a high-precision level to attain impeccable alignment. The unit's axial level should be a flawless 0.05/1000mm, while its horizontal level must meet 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Achieve perfect coupling alignment. Before beginning, ensure these vital steps are followed:
1) Main power supply must be switched off;
2) Detach the protective coupling shield for safe access;
3) Remove the intermediate section of the diaphragm coupling;
4) Verify the motor installation plane's flatness, ensuring it is free from debris and unwanted materials.
5) Motor bolt holes should exceed bolt size, facilitating easy adjustments and movement.
6) Ensure there are ample stainless steel gaskets for the motor's base. These gaskets must be pristine and smooth, avoiding any use of substandard alternatives.
7) Employ either a dial indicator or a laser alignment meter with precision accuracy of 0.01mm, as provided by the customer.
8) Have the essential bracket ready for the dial indicator, as illustrated in the accompanying diagram;
9) A dedicated motor wheel hub mounting bracket ensures precise dial indicator placement on the hub's edge, aiding in accurate measurements.
10) Fine-tune the adjustment bolts around the motor feet to align both compressor and motor with precision, ensuring the maximum outer circle deviation does not surpass 0.05mm.
11) Conclude by securely tightening the motor foot bolts, then re-assess both the outer circle and end face runouts for optimal precision.;
12) After the motor's idle test, seamlessly reinstall the coupling's intermediate section.
3.3.4 With precision alignment and 'levelness' adjustments complete, secure the anchor bolts. Post-operation, re-tighten to ensure unwavering mechanical integrity.
3.3.5 The impeller, a high-speed marvel, demands impeccably clean pipelines to prevent irreversible damage. Ensure all connection pathways meet steam corrosion standards, or enhance with solid-liquid separation equipment as needed.
3.3.6 Seamlessly integrate compressor inlet and outlet pipes per the PI diagram, ensuring pipelines are independently supported to avoid undue stress on the compressor.
3.3.7 Once the primary fan along with its supporting equipment has been meticulously installed and the concrete foundation has achieved full solidity, the next step is to initiate the operational test of the compressor. This critical phase ensures that every component is in optimal condition for seamless performance.
3.3.8 Position the compressor's sophisticated electric control cabinet strategically within a 5-meter radius of the compressor unit. For enhanced safety and efficiency, the connection from the compressor to this cabinet must be executed using a threading pipe routed discreetly underground. Upon secure placement of the cabinet, proceed to meticulously link the wiring terminals within the cabinet to the lines at the remote Distributed Control System (DCS), ensuring flawless integration and functionality.
