MVR, an impressive abbreviation for Mechanical Vapor Recompression, represents a revolutionary energy-saving technology crafted to significantly diminish the reliance on external energy sources. This is achieved through the innovative reuse of secondary steam energy that it inherently generates. At its core, the principle is elegantly simple yet incredibly effective: the secondary steam produced by the evaporator is meticulously compressed using a steam compressor designed for high energy efficiency. This process ingeniously transforms electrical energy directly into thermal energy. As a result, there is an increase in both the pressure and temperature of the secondary steam, which is then ingeniously cycled back to the evaporator. This recycled steam is used to heat the materials, initiating evaporation and thus achieving a harmonious cycle of latent heat of vaporization recycling for the secondary steam.
The DM series Single-stage Geared Steam Compressor stands as a pinnacle of engineering within the realm of steam compression technology. This series predominantly comprises the robust compressor body, seamlessly integrated with a coupling, a finely tuned gearbox, a sophisticated lubrication system, a reliable motor, as well as a state-of-the-art electric instrument and anti-surge control system. This meticulously engineered compressor is celebrated for its compact structure, which not only enhances its aesthetic appeal but also significantly simplifies the maintenance process, making it an ideal choice for those seeking efficiency and reliability.
3.3.1 Begin by strategically positioning the compressor base integrally onto the foundation. Utilize wedge-shaped shims beneath the base to finely adjust the level of the unit, ensuring precision.
Employ alternating placements of the wedge-shaped irons. Once the unit is meticulously leveled, secure the wedges by spot welding at 4 to 5 points, ensuring stability.
These wedges should be custom-manufactured and installed by you, tailored to your specific situation. Ensure the contact surfaces are meticulously finished for even contact of the inclined plane.
It is crucial that the bearing capacity of the wedge iron does not exceed an impressive 40Kg/cm2).
3.3.2 Achieve perfect leveling by using a high-precision level. The stringent leveling requirements demand an axial level of 0.05/1000mm and a horizontal level of 0.10/1000mm for optimal performance.
level of the unit is 0.10/1000mm.
3.3.3 Center the coupling with finesse. Before starting the critical alignment process, ensure these essential prerequisites are met:
1) Ensure safety by turning off the main power supply;
2) Carefully remove the coupling shield for unencumbered access;
3) Disassemble the diaphragm coupling intermediate section to facilitate alignment;
4) Inspect the motor installation plane for flatness, ensuring it's free of any foreign materials, dirt, or obstructions;
5) Verify that the motor bolt holes exceed bolt sizes, allowing for easy loosening to adjust the motor as needed;
6) Prepare sufficient stainless steel gaskets to provide unwavering support for the motor, ensuring they are free of attachments, perfectly flat, and not long or thin.
7) Employ a dial indicator or a laser alignment meter with exceptional accuracy (0.01mm), which must be provided by the customer;
8) Prepare the necessary bracket to support the dial indicator as illustrated in the accompanying figure;
9) Utilize the motor wheel hub mounting bracket to hold the dial indicator on the wheel hub's edge while placing the dial indicator probe on the compressor wheel hub's outer edge;
10) By fine-tuning the adjustment bolts around the motor feet, align the compressor and motor center lines impeccably. Allowable maximum deviation for the outer circle is 0.05mm, with the motor shaft center line positioned slightly higher than the compressor low-speed shaft center line. Maintain coupling end face deviation between 0.03~0.05mm;
11) Conclude by tightening the motor foot bolts and meticulously reviewing the outer circle runout and end face runout of the coupling for assurance;;
12) Finalize the process by reinstalling the coupling intermediate section post motor idling test, ensuring optimal alignment and function.
3.3.4 After achieving the perfect 'levelness' and alignment of the casing, firmly tighten the anchor bolts. Post mechanical operation or trial operation, loosen and retighten bolts for reinforced security.
3.3.5 The impeller's high-speed rotation necessitates that no solid or liquid enters, as it can inflict irreversible damage. Ensure the inlet and outlet pipelines linked to the compressor are pristine and meet the system's stringent steam corrosion grade requirements. Pipelines failing to comply require rectification.It is prudent to incorporate solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the straight pipe at the compressor inlet to safeguard the system.
3.3.6 Proceed with the installation of compressor inlet and outlet pipes. Adhere to the PI diagram for incorporating relevant pipeline accessories. Pipelines connected to the compressor must be supported by a separate bracket to avoid burdening the compressor body with their weight.
3.3.7 Once the main fan along with its auxiliary apparatus is meticulously installed and the concrete foundation has achieved full solidity, you can embark on conducting the compressor operation test. This marks a pivotal step in ensuring the seamless functionality and reliability of your Guide Vane Adjustment Steam Compressor for Sugar Liquid Processing.
3.3.8 It is essential to position the electric control cabinet of the compressor within a distance of 5 meters from the compressor itself. For optimal safety and efficiency, ensure that the wiring from the compressor to the control cabinet is carefully threaded through an underground conduit. Once the electric control cabinet is securely installed, proceed to connect the wiring terminals in the cabinet with the lines at the remote DCS. This establishes a robust and efficient communication network essential for the operation of your cutting-edge compressor system.
