MVR, an acronym for Mechanical Vapor Recompression, stands as a revolutionary energy-conserving technology. It significantly minimizes the need for external energy by ingeniously repurposing the secondary steam energy that it produces. The core principle of this advanced technology is that the evaporator's generated secondary steam is expertly compressed by a highly efficient steam compressor. This process transforms electrical energy into thermal energy, causing an increase in both pressure and temperature of the secondary steam. Subsequently, this temperature rise allows the secondary steam to return to the evaporator, where it acts to heat the materials and facilitate evaporation. In this way, the latent heat of vaporization of the secondary steam is masterfully recycled, showcasing an excellent example of sustainable energy usage.
The DM series Single-stage Geared Steam Compressor presents an innovation in design, consisting of a compressor body, coupling, gearbox, lubrication system, motor, electrical instruments, and an anti-surge control system. This state-of-the-art equipment features a compact structure, making it not only space-efficient but also ensuring ease of maintenance. It is meticulously engineered to offer superior performance and reliability, designed to meet the demanding needs of modern industrial applications.
3.3.1 Begin by placing the compressor base integrally on the foundation, ensuring stability and precision with wedge-shaped shims. These wedges are crucial for achieving a perfectly level unit.
Skillfully alternate two wedge-shaped irons. Once the compressor is level, proceed to spot weld the wedges securely at 4 to 5 points, ensuring steadfast support and alignment.
Craft the wedges as per the specific requirements of your setup. The contact surfaces should be carefully finished for even contact on inclined planes, providing maximum stability.
The load-bearing capability of each wedge iron should not exceed an impressive 40Kg/cm2).
3.3.2 Employ a precision level to ascertain the perfect horizontal and axial leveling of your unit. The axial precision requirement stands at a meticulous 0.05/1000mm, while the horizontal standard is 0.10/1000mm.
Ensure your unit meets these strict leveling standards for optimal performance and longevity.
3.3.3 Align the coupling with precision. Before initiating this process, adhere to the following imperative steps:
1) Securely turn off the main power supply to ensure safety and prevent any electrical hazards;
2) Carefully remove the coupling shield to provide access for alignment adjustments;
3) Take out the diaphragm coupling intermediate section to facilitate accurate alignment;
4) Assess the flatness of the motor installation plane. Ensure it is free from debris, dirt, or any obstructions for a seamless setup.
5) Ensure the motor bolt hole is sufficiently larger than the bolt itself, allowing for fine adjustments during installation.
6) Have a ready supply of perfectly flat and clean stainless steel gaskets. Avoid using long, thin gaskets that could compromise the integrity of the alignment process.
7) Utilize a dial indicator or laser alignment meter with a precision of 0.01mm, ensuring your equipment is calibrated to perfection.
8) Prepare a sturdy bracket to support the dial indicator, as depicted in the accompanying illustration.
9) Use the motor wheel hub mounting bracket to securely attach the dial indicator. Position the probe accurately on the compressor wheel hub's outer edge.
10) Adjust the motor feet bolts meticulously to align the compressor and motor center lines as closely as possible, allowing only a minimal deviation of 0.05mm.
11) Conclude by tightening the motor foot bolts, then review and verify the outer circle and end face runout of the coupling for assurance of precision.;
12) Post-alignment, install the coupling's intermediate section following a successful motor idling test.
3.3.4 Once the unit is perfectly leveled and aligned, proceed to tighten the anchor bolts. After a successful mechanical operation or trial, revisit these bolts for final tightening to ensure enduring stability.
3.3.5 The impeller's high-speed rotation necessitates strict cleanliness of the inlet and outlet pipelines to prevent irreversible damage. Ensure these pathways are pristine and adhere to the steam corrosion grade requirements.To further safeguard the system, consider installing solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the compressor’s inlet pipe.
3.3.6 Install the compressor's inlet and outlet pipes with precision, adhering closely to the PI diagram for accessory installation. Ensure that the associated pipelines are supported independently by brackets, not by the compressor body, to preserve its integrity.
3.3.7 Once the primary fan and its auxiliary apparatus have been meticulously installed and the concrete foundation reaches full solidity, the compressor is primed and ready for a comprehensive operational test. This crucial step ensures seamless future operations and optimal performance.
3.3.8 Ensure the electric control cabinet for the compressor is strategically placed within a convenient radius of 5 meters. The conduit carrying the wiring from the compressor to this cabinet should be expertly routed through underground threading pipes for safety and efficiency. Following the precise placement of the control cabinet, connect its wiring terminals flawlessly with the lines at the remote DCS, ensuring a harmonious integration and reliable communication.
