MVR, standing for Mechanical Vapor Recompression, represents a groundbreaking energy-saving technology designed to dramatically reduce the need for external energy sources. This is achieved by ingeniously reutilizing the secondary steam energy it generates. The core principle at play involves the secondary steam created by the evaporator being expertly compressed using a high-efficiency steam compressor. This process transforms electrical energy into thermal energy, significantly elevating both the pressure and temperature of the secondary steam. The increased temperature then allows the secondary steam to be channeled back into the evaporator, efficiently heating the materials to induce evaporation. This elegant cycle masterfully recycles the latent heat of vaporization of the secondary steam, optimizing energy usage and enhancing sustainability.
The DM series Single-stage Geared Steam Compressor is an engineering marvel, comprising various essential components such as the compressor body, a robust coupling, a precision gearbox, a sophisticated lubrication system, a powerful motor, an advanced electric instrument, and a cutting-edge anti-surge control system. This compressor is ingeniously designed with a compact structure, ensuring not only space-saving efficiency but also simplifying maintenance procedures. This seamless blend of functionality and convenience makes the DM series a top-tier choice for those seeking reliability and performance.
3.3.1 Begin by positioning the compressor base firmly on its foundation. Utilize wedge-shaped shims placed beneath the base to achieve perfect leveling. These shims are crucial for maintaining the integrity and balance of the unit, ensuring a seamless operation.
Carefully position two wedge-shaped irons in an alternating sequence. Once the unit is skillfully leveled, secure the wedges by spot welding them at 4 to 5 points. This meticulous process ensures a stable and reliable setup.
The manufacturing and installation of the wedges should be executed by the user, tailored to the specific conditions of the installation site. The contact surface needs precision finishing to guarantee even contact of inclined planes, which is essential for optimal performance.
plane, and the bearing capacity of the wedge iron shall not exceed 40Kg/cm², ensuring safety and functionality under operational stresses.2).
3.3.2 Achieve precise leveling with a level tool. Adhere to the stringent leveling standards: the axial level should be 0.05/1000mm, and the horizontal level must not exceed 0.10/1000mm. This precision is vital for the unit's optimal function.
level of the unit is 0.10/1000mm.
3.3.3 For perfect alignment, the coupling must be centered. Prior to initiating alignment, ensure these essential prerequisites are fulfilled:
1) Deactivate the main power supply to ensure safety during the procedure.
2) Detach the coupling shield with care, ensuring all components are easily accessible.
3) Remove the diaphragm coupling's intermediate section. This step is critical for accessing the alignment area.
4) Inspect the motor installation plane, confirming it is free from debris, dirt, and any unwanted attachments that could impede a smooth installation.
5) Ensure the motor bolt holes are adequately sized to allow the bolts to be loosened for precise motor adjustments.
6) Gather sufficient stainless steel gaskets to fully support the motor's footing. These gaskets must be devoid of attachments, perfectly flat, and not excessively long or thin to avoid skewed adjustments.
7) Utilize a highly accurate dial indicator or a laser alignment meter, with precision of 0.01mm, to achieve the highest alignment accuracy. This equipment should be supplied by the customer.
8) Prepare a robust bracket to support the dial indicator, ensuring stability during measurement. Refer to the accompanying illustration for correct setup.
9) Employ the motor hub mounting bracket for precise dial indicator placement on the wheel hub edge, allowing accurate readings of the compressor wheel hub.
10) Adjust the motor feet using adjustment bolts to align the compressor and motor center lines accurately. The maximum outer circle deviation should be 0.05mm, with the motor shaft center line positioned slightly higher than the compressor low-speed shaft center line. Ensure coupling end face deviation is within 0.03~0.05mm.
11) Conclude by securely tightening the motor foot bolts, then meticulously review and confirm the outer circle and end face runout of the coupling for assurance of alignment fidelity.;
12) After successful motor idling and testing, proceed with the installation of the coupling's intermediate section.
3.3.4 Once the 'levelness' and alignment of the casing have been impeccably adjusted, firmly secure the anchor bolts. Post mechanical operation or trial testing, loosen and retighten the bolts to ensure continued precision.
3.3.5 The impeller, a crucial high-speed component, must be safeguarded from any solid or liquid intrusion, as such breaches can cause irreversible damage. It is paramount to verify that all connected inlet and outlet pipelines are immaculate and conform to the system's steam corrosion grade requirements. Non-compliant pipelines necessitate immediate rectification.It is strongly advised to install solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, ahead of the compressor's straight pipe inlet to prevent contamination.
3.3.6 Proceed with the installation of compressor inlet and outlet pipes. Ensure the installation of all necessary pipeline accessories in accordance with the PI diagram. Additionally, support the pipeline externally rather than relying on the compressor body for stability, preventing undue stress on the system.
3.3.7 Upon the completion of the installation of the main fan and its auxiliary components, and once the concrete has fully set, the stage is magnificently set for the compressor operation test. This critical step ensures that all elements are harmoniously working in perfect unison.
3.3.8 Position the electric control cabinet for the compressor within an optimal 5-meter range of the compressor itself. The sophisticated wiring journey from the compressor to the electric control cabinet should be elegantly encased in threading pipes that travel discreetly underground. Once the electric control cabinet is securely settled, seamlessly integrate its wiring terminals with the distant DCS lines, ensuring a flawless connection.
