MVR, an acronym for Mechanical Vapor Recompression, represents a groundbreaking energy-preserving technology designed to significantly decrease reliance on external energy sources by ingeniously harnessing the power of the secondary steam it produces. The core principle involves compressing the secondary steam, emanating from the evaporator, using a highly efficient steam compressor. This process masterfully transforms electrical energy into thermal energy, elevating both the pressure and temperature of the secondary steam. Consequently, the heightened temperature seamlessly returns to the evaporator, effectively heating the materials to induce evaporation. This innovative cycle brilliantly recycles the latent heat of vaporization of the secondary steam, showcasing a triumph in sustainable energy utilization.
The DM series Single-stage Geared Steam Compressor is an engineering marvel, encompassing the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system, all within a meticulously compact design. This thoughtful assembly ensures not only operational excellence but also remarkable ease in maintenance, making it a dependable choice for modern engineering needs.
3.3.1 Gracefully position the compressor base onto its designated foundation. To achieve perfect leveling, place wedge-shaped shims underneath the base, meticulously adjusting the unit level with precision.
Carefully alternate the placement of two wedge-shaped irons until the unit is perfectly leveled. Proceed to spot weld these irons securely at 4 to 5 strategic points, ensuring stability.
The manufacturing and installation of the wedge are the responsibility of the user, tailored to the specific conditions encountered. These surfaces must be impeccably finished for even contact.
plane. It is crucial that the bearing capacity of the wedge iron does not exceed a maximum of 40Kg/cm2).
3.3.2 Utilize a level to meticulously assess the levelness. The unit's leveling standards demand an axial level precision of 0.05/1000mm, while horizontal precision requires 0.10/1000mm.
Ensure these high standards for optimal performance and longevity.
3.3.3 Attain precision in coupling centering, ensuring all prerequisites are met before any alignment action:
1) Ensure absolute safety by turning off the main power supply;
2) Gently remove the coupling shield to proceed;
3) Detach the diaphragm coupling's intermediate section carefully;
4) Meticulously inspect the motor installation plane, confirming it is free of any debris, dirt, or attachments;
5) Ensure the motor bolt holes are adequately larger than the bolts to facilitate smooth adjustments;
6) Equip yourself with a sufficient number of stainless steel gaskets to support the motor, ensuring they are pristine and flat, avoiding any lengthy gaskets for finely-tuned adjustments;
7) Utilize precision instruments such as a dial indicator or a laser alignment meter with an exactitude of 0.01mm, personally acquired to ensure utmost accuracy;
8) Prepare a sturdy bracket, as illustrated below, to support the dial indicator;
9) Employ a motor hub mounting bracket for positioning the dial indicator on the wheel hub's edge, setting the probe on the compressor wheel hub's outer rim;
10) Carefully adjust the motor feet bolts to align the compressor and motor center lines, achieving a maximum outer circle deviation of 0.05mm. The motor shaft should slightly exceed the compressor's low-speed shaft center line, with the coupling end face at 0.03~0.05mm;
11) Securely fasten the motor foot bolts, revisiting and verifying the outer circle and end face runout for impeccable alignment;;
12) After successful motor idling tests, reinstall the coupling’s intermediate section meticulously.
3.3.4 Post adjustment of the casing's levelness and alignment, firmly tighten the anchor bolts. After the mechanical operation or trial run, relearn and retighten for reinforced stability.
3.3.5 The impeller, a swiftly rotating marvel, demands an immaculate environment where no solids or liquids intrude, to prevent harm. Ensure all connected pipelines are pristine and meet steam corrosion standards, rectifying any that falter.Implement solid-liquid separation equipment, such as gas scrubbers or sedimentation tees, before the compressor’s inlet to safeguard its function.
3.3.6 Thoughtfully install compressor inlet and outlet pipes. Adhere to PI diagrams for proper pipeline accessory placement. Ensure pipelines are independently supported, never burdening the compressor body.
3.3.7 Once the central fan and its supplementary devices are securely installed and the concrete has thoroughly hardened, it's time to initiate the thrilling operation test of the compressor. This crucial step ensures optimal functionality and performance for your peace of mind.
3.3.8 Strategically place the compressor's electric control cabinet within a convenient 5 meters of the compressor itself. Ensure seamless connectivity by threading the wiring through a protective pipe that runs underground. Once your electric control cabinet is perfectly positioned, expertly link the wiring terminals within it to the lines at the remote DCS, ensuring flawless communication and control.
