MVR, an acronym for Mechanical Vapor Recompression, revolutionizes energy efficiency by drastically cutting down on external energy requirements. This pioneering technology ingeniously recycles the energy inherent in secondary steam, dramatically enhancing sustainability. The core mechanism involves the secondary steam, born from the evaporator, being supercharged by a high-efficiency steam compressor. This marvel of engineering transforms electrical input into potent thermal energy, elevating both the pressure and temperature of the steam. This energized secondary steam is then recycled back into the evaporator, where it actively heats the materials to trigger evaporation. The latent heat of vaporization is thus ingeniously reused, illustrating the perfect harmony between energy conservation and innovation.
The DM series Single-stage Geared Steam Compressor stands as a testament to advanced engineering with its robust composition, featuring a compressor body, coupling, gearbox, lubrication system, motor, electric instrumentation, and an anti-surge control system. Its compact design ensures easy maintenance, offering a seamless blend of sophisticated technology and user-friendly operation. This compressor is engineered for those who value efficiency and reliability, providing an indispensable asset for any operation that demands excellence and durability.
3.3.1 Begin by placing the compressor base as a whole upon your carefully prepared foundation. Utilize wedge-shaped shims strategically underneath the base to achieve perfect leveling of the unit. Ensure precision at every step for optimal performance.
With meticulous attention, position two wedge-shaped irons in an alternating pattern. Once the unit attains perfect level, proceed to spot weld the irons securely at 4 to 5 strategic points. A touch of finesse ensures enduring stability.
Craft and install the wedges, honed to perfection, ensuring an even contact surface and a robust bearing capacity. Customize the manufacturing to align with specific situational demands.
Be mindful that the bearing load of each wedge iron remains under 40Kg/cm2).
3.3.2 Employ a precision level to achieve ideal alignment of the unit. Aim for unparalleled excellence with an axial level precision of 0.05/1000mm and a horizontal level of 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Center the coupling with impeccable precision. Prioritize the following pre-alignment checks to ensure flawless execution:
1) Deactivate the primary power supply to ensure complete safety;
2) Gently remove the protective coupling shield to gain complete access;
3) Carefully detach the intermediate section of the diaphragm coupling for unhindered alignment;
4) Verify the motor installation surface for absolute cleanliness and the absence of any debris;
5) Ensure the motor bolt holes exceed bolt size for seamless adjustments and secure alignment;
6) Prepare an ample supply of pristine stainless steel gaskets. They must be free from contaminants and perfectly flat to ensure precise adjustments.
7) Arm yourself with a dial indicator or a laser alignment meter boasting a precision of 0.01mm, a must for any serious craftsman;
8) Have ready a sturdy bracket to support your dial indicator, as illustrated below;
9) Use the motor wheel hub mounting bracket to skillfully position a dial indicator on the hub's outer edge, ensuring precise alignment;
10) Fine-tune the adjustment bolts around the motor feet to achieve near-perfect alignment of the compressor and motor center lines, with a maximum deviation of 0.05mm, ensuring optimized operation.
11) Securely fasten the motor foot bolts, then meticulously review the outer circle and end face runouts for impeccable precision.;
12) Conclude by reinstalling the coupling intermediate section following a successful motor idling test, readying the system for operational excellence.
3.3.4 Once levelness and meticulous alignment are achieved, securely fasten the anchor bolts. Proceed to tighten these bolts once more following the mechanical operation or trial, for added assurance.
3.3.5 The impeller, a high-speed marvel, demands absolute protection against any foreign solid or liquid intrusion, which could inflict irreversible damage. Ensure all connected pipelines meet the necessary steam corrosion standards. Rectify any discrepancies and elevate system integrity with utmost thoroughness.Equip your system with solid-liquid separation apparatus such as a gas scrubber or sedimentation tee, positioned before the compressor inlet straight pipe, to bolster performance and protection.
3.3.6 Proceed with the installation of the compressor’s inlet and outlet pipes. Adhere to the PI diagram for accessory placements, supporting pipelines with independent brackets to ensure no undue weight bears on the compressor, promising reliable performance.
3.3.7 Upon the complete installation of the main fan and its complementary equipment, and once the concrete has fully cured, it's time to embark on the thrilling phase of testing the compressor in action. This operation test is a pivotal moment to ensure everything functions seamlessly.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within a 5-meter radius from the compressor itself. It's essential that the connection between the compressor and its control cabinet is achieved using a threading pipe, which must be skillfully routed underground. Once the electric control cabinet is in its rightful place, ensure to meticulously link the wiring terminals within the cabinet to the remote DCS lines, establishing a robust and efficient connection.
