The MVR (Mechanical Vapor Recompression) technology represents a groundbreaking leap in energy conservation. This sophisticated energy-saving technique dramatically slashes the need for external energy by ingeniously harnessing and reusing the secondary steam energy it produces. The process operates on a brilliant principle: the evaporator-generated secondary steam is compressed using an exquisitely efficient steam compressor, transforming electrical energy into thermal energy. This transformation elevates the pressure and temperature of the secondary steam, which is then ingeniously redirected back to the evaporator. As it returns, this steam elevates the temperature of the materials, triggering evaporation and thus achieving a remarkable recycling of the secondary steam's latent heat of vaporization.
The DML series Low Temperature Rise Steam Compressor is a marvel of engineering, crafted with precision and innovation. This advanced equipment primarily consists of a meticulously designed compressor body, which includes essential components like the volute, impeller, main shaft, bearing housing, and seals. Additionally, it is equipped with a coupling, motor, and an array of sophisticated electric instruments. These elements work in perfect harmony to ensure enhanced efficiency and superior performance, making it a standout choice in the realm of steam compressors.
3.3.1 Begin by securing the compressor base integrally onto the pre-prepared foundation. Carefully position wedge-shaped shims beneath the base to fine-tune the unit's level.
Place pairs of wedge-shaped irons alternately. Once the unit is impeccably level, gingerly spot weld the wedges at 4 to 5 strategic points. These wedges should be
meticulously crafted and installed by the user in accordance with the specific requirements of the site, ensuring the contact surfaces are immaculate for
perfect contact on inclined planes. The wedge iron's bearing capacity should not exceed 40Kg/cm2).
3.3.2 Employ a precise level to achieve optimal balance. The unit's leveling parameters are as follows: the axial level must achieve a precision of 0.05/1000mm,
and the horizontal level should maintain a precision of 0.10/1000mm.
3.3.3 Achieve perfect coupling alignment by adhering to the following preparatory steps:
1) Ensure the main power supply is fully deactivated.
2) Dismantle the protective coupling shield with care.
3) Remove the intermediate section of the diaphragm coupling.
4) Thoroughly check the motor installation plane for any foreign materials, ensuring pristine cleanliness.
5) Verify that motor bolt holes are adequately larger than the bolt size to facilitate seamless loosening and motor adjustments.
6) Prepare an ample supply of stainless steel gaskets to support the motor's foot. These gaskets must be devoid of attachments and perfectly flat.
7) Utilize a highly accurate dial indicator or laser alignment meter, boasting an accuracy of 0.01mm (procured by the customer).
8) Assemble the appropriate bracket to support the dial indicator as illustrated in the accompanying diagram.
9) The motor wheel hub mounting bracket is designed for affixing a dial indicator to the edge of the hub, positioning the probe on the compressor hub's periphery.
10) By meticulously adjusting the bolts around the motor feet, align the compressor and motor center lines to be nearly congruent, with a maximum deviation of 0.05mm for the outer circle (ensuring the motor shaft center line is marginally above the compressor low-speed shaft center line). Coupling end face tolerance should be between 0.03mm to 0.05mm.
11) Conclude by securely tightening the motor foot bolts, then verify the coupling's outer circle and end face runout measurements.;
12) After successful motor idling verification, attach the coupling's intermediate section.
3.3.4 Once the 'levelness' and alignment of the casing are perfected, fortify the anchor bolts. Post mechanical operation or trial run, loosen and retighten these bolts for optimal security.
3.3.5 The impeller, a high-speed rotating marvel, demands a pristine environment. Any solid or liquid intrusion could incur irreversible damage. Ensure that all inlet and outlet pipelines are scrupulously clean and adhere to the system's steam corrosion standards. Non-compliant pipelines require immediate rectification. Consider integrating solid-liquid separation equipment, such as gas scrubbers or sedimentation tees, prior to the straight pipe at the compressor's inlet for added protection.
3.3.6 Seamlessly install the compressor's inlet and outlet pipes. Follow the PI diagram for the correct installation of all necessary pipeline accessories. Ensure that pipelines are independently supported and not burdening the compressor body with their weight.
3.3.7 Upon successful installation of the main fan and its essential auxiliary equipment, and once the concrete has reached full solidity, you are ready to proceed with the compressor operation test. This crucial step will ensure the optimal functioning of your system, allowing you to experience the exceptional performance and reliability of the Low Temperature Rise Steam Compressor with Enhanced Efficiency and Performance.
3.3.8 It is advised that the electric control cabinet of the compressor be strategically positioned within a 5-meter proximity to the compressor itself. For a seamless and secure connection, the wiring should be routed via threading pipes that are laid underground. Once the electric control cabinet is properly stationed, it's essential to link the wiring terminals within the cabinet to the lines at the remote DCS. This careful installation process ensures a flawless integration, enhancing the operational efficiency and safety of your compressor system from NANTONG DART-RICH FAN CO.,LTD.
