MVR, the abbreviation for Mechanical Vapor Recompression, represents an innovative and energy-efficient technology designed to significantly cut down the need for external energy by cleverly reutilizing the secondary steam energy it produces. At the heart of this cutting-edge technology lies a compelling principle: the secondary steam generated by the evaporator is skillfully compressed using a high-efficiency steam compressor. This transformation converts electrical energy into thermal energy, leading to an increase in both pressure and temperature of the secondary steam. Subsequently, the elevated temperature allows the secondary steam to return to the evaporator, where it plays a crucial role in heating the materials and driving evaporation. This ingenious process effectively recycles the latent heat of vaporization of the secondary steam, ushering in a new era of sustainable energy utilization.
The DML series Low Temperature Rise Steam Compressor stands as a pinnacle of engineering excellence. It is intricately crafted with several key components, including a robust compressor body, which consists of the volute, impeller, main shaft, bearing housing, and seal, among others. Complementing this is a precision coupling, a reliable motor, and sophisticated electric instruments, all working harmoniously together. This remarkable assembly ensures top-notch performance and efficiency, making it a pivotal addition to any energy-conscious operation.
3.3.1 To commence the installation of your Low Temperature Rise Steam Compressor with Enhanced Guide Vane Control, carefully place the compressor base integrally on its designated foundation. Introduce wedge-shaped shims beneath the base to perfectly balance the unit. This is pivotal to maintaining stability and performance.
Position two wedge-shaped irons alternately. Once the unit is precisely leveled, secure these wedges by spot welding at 4 to 5 key points, ensuring a steadfast installation.
The manufacture and installation of the wedge must be performed by the user, tailored to the specific conditions of your environment. The contact surface should be meticulously finished to guarantee even engagement of the inclined plane.
plane, ensuring the wedge iron's bearing capacity does not exceed 40Kg/cm2).
3.3.2 Employ a precision level to verify the unit's alignment. The exacting leveling standards for this unit require an axial level of 0.05/1000mm and a horizontal level of 0.10/1000mm, ensuring optimal operation and efficiency.
level of the unit is 0.10/1000mm.
3.3.3 Perfect coupling alignment is paramount. Before initiating the alignment procedures, ensure these prerequisites are met:
1) Disconnect the primary power supply to guarantee safety;
2) Dismantle the coupling shield for unhindered access;
3) Remove the diaphragm coupling's intermediate section to prepare for alignment;
4) Verify the flatness of the motor installation surface, ensuring it is devoid of any debris or contaminants;
5) Ensure the motor's bolt holes are sufficiently larger than the bolts to facilitate easy adjustments;
6) Have a supply of stainless steel gaskets ready to fully support the motor feet, ensuring no impurities and maintaining a flat, stable contact. Avoid using elongated or thin gaskets for adjustment.
7) Utilize a highly accurate dial indicator or laser alignment tool with a precision of 0.01mm, which should be sourced by the customer;
8) Prepare a suitable bracket to support the dial indicator, as depicted in the accompanying illustration;
9) Employ the motor hub mounting bracket to securely attach the dial indicator on the wheel hub, with the probe positioned on the outer edge of the compressor hub.
10) By delicately adjusting the bolts around the motor feet, align the compressor and motor center lines. Ensure the maximum deviation of the outer circle is within 0.05mm, with the motor shaft center line slightly elevated compared to the compressor low-speed shaft. Maintain a coupling end face tolerance of 0.03~0.05mm.
11) As the final step, secure the motor foot bolts and thoroughly inspect the outer circle and end face runout of the coupling.;
12) Complete the installation by fitting the coupling's intermediate section post-motor idling test.
3.3.4 Once the casing's 'levelness' and alignment are perfected, tighten the anchor bolts securely. Post mechanical operation or trial run, it is crucial to loosen and retighten these bolts to ensure enduring stability.
3.3.5 The impeller, a high-speed rotating marvel, requires diligent care. Any foreign solid or liquid entering can inflict irreversible damage. Thus, it is essential to maintain the inlet and outlet pipelines in pristine condition, meeting the system's steam corrosion standards. Non-compliant pipelines must be swiftly rectified. We recommend installing solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the compressor inlet's straight pipe for enhanced protection.
3.3.6 Strategically install the compressor's inlet and outlet pipes. Ensure all import and export pipelines are equipped with the necessary accessories as per the PI diagram. Support these pipelines with independent brackets, as they must not bear any weight on the compressor body to avoid undue stress.
3.3.7 Once the main fan and all its supportive equipment are meticulously installed and the concrete foundation has fully solidified, you can seamlessly proceed to conduct the compressor operation test. This crucial step ensures that everything is meticulously aligned and ready for optimal performance.
3.3.8 Position the compressor's electric control cabinet strategically within a convenient 5-meter radius of the compressor itself. For a streamlined and protected setup, ensure that the wiring from the compressor to the electric control cabinet is securely connected using threading pipes that run underground. Once the electric control cabinet is perfectly positioned, efficiently link the wiring terminals in the cabinet to the remote DCS lines, ensuring a seamless and uninterrupted connection.
