MVR, which stands for mechanical vapor recompression, represents a cutting-edge energy-saving technology aimed at significantly reducing the necessity for external energy sources. This innovative system achieves remarkable efficiency by cleverly reutilizing the secondary steam energy it generates. The foundational principle is elegantly simple: secondary steam produced by the evaporator is expertly compressed using a high-energy efficiency steam compressor. This process skillfully transforms electrical energy into valuable thermal energy, resulting in an increase in the pressure and temperature of the secondary steam. This heightened temperature enables the steam to return to the evaporator, where it effectively heats materials and facilitates further evaporation. The outcome is an ingenious recycling of the latent heat of vaporization of the secondary steam, ensuring sustainability and enhanced energy conservation.
The DM series Single-stage geared steam compressor is a marvel of engineering that showcases a comprehensive design. This compressor predominantly comprises several integral components, including the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. With its compact structural design, it offers unparalleled convenience for maintenance, making it an ideal choice for those seeking efficiency without the hassle. Whether in the pharmaceutical or wastewater treatment sectors, this compressor stands out for its reliability and ease of use.
3.3.1 Begin by securely situating the compressor base seamlessly onto the prepared foundation. Utilize wedge-shaped shims strategically placed beneath the base to achieve a perfect level.
Alternately arrange two wedge-shaped irons for optimal stability. Once the unit is perfectly leveled, apply spot welds at 4 to 5 strategic points to fix the wedges in place.
These wedges should be custom-fabricated and installed by the user to suit the specific conditions. Ensure the contact surfaces are meticulously finished for even contact with the inclined plane.
The load-bearing capacity of each wedge iron should not exceed the limit of 40Kg/cm2).
3.3.2 Employ a precision level to ascertain the perfect alignment. The unit’s axial and horizontal leveling criteria are set at an ultra-precise 0.05/1000mm and 0.10/1000mm, respectively.
level of the unit is 0.10/1000mm.
3.3.3 Achieve flawless coupling centering. Before proceeding with alignment, ensure the following preconditions are meticulously met:
1) Disengage the main power supply for utmost safety.
2) Carefully remove the coupling shield to access the components.
3) Dismantle the diaphragm coupling's intermediate section with precision.
4) Scrutinize the motor installation plane for flatness, ensuring it's impeccably clean and free from debris.
5) Ensure motor bolt holes are adequately sized to allow bolt adjustments for optimal motor alignment.
6) Have an ample supply of pristine stainless steel gaskets ready, ensuring their complete flatness sans any attachments.
7) Utilize a highly accurate dial indicator or laser alignment meter, measuring precisely to 0.01mm, as provided by the customer.
8) Set up the dial indicator support bracket as per the accompanying diagram for stability and accuracy.
9) Mount the dial indicator on the motor wheel hub bracket, positioning the probe at the outer edge of the compressor wheel hub for precision readings.
10) Adjust the motor feet’s bolts to ensure the compressor and motor center lines are perfectly aligned, maintaining a minuscule outer circle deviation.
11) Securely fasten the motor foot bolts and reassess the outer circle and end face runouts for assured precision.;
12) Conclude with the installation of the coupling intermediate section post a successful motor idling test.
3.3.4 Post completion of 'levelness' and alignment adjustments, ensure the anchor bolts are tightened firmly. Post mechanical operation, loosen and retighten the bolts for lasting security.
3.3.5 The impeller is crafted for high-speed rotations; any solid or liquid intrusion can inflict severe damage. Ensure connected inlet and outlet pipelines are pristine and meet the system's steam corrosion standards.Consider integrating solid-liquid separation equipment like a gas scrubber or sedimentation tee before the compressor inlet to safeguard against potential contamination.
3.3.6 Proceed with the installation of compressor inlet and outlet pipes, incorporating appropriate pipeline accessories as per the PI diagram. Ensure pipeline weight is independently supported, safeguarding the compressor body from undue stress.
3.3.7 Once the main fan, along with its supporting equipment, is firmly installed and the concrete foundation has fully cured, you may proceed with conducting the compressor's operational test. This is a crucial step to ensure the effectiveness and reliability of the system in treating wastewater with precision.
3.3.8 For optimal performance and safety, the electric control cabinet of the compressor should be strategically positioned within a five-meter radius of the compressor. The connection from the compressor to the electric control cabinet should be expertly executed using threading pipes, which must be routed underground to avoid exposure. Once the electric control cabinet is securely stationed, it is vital to integrate the wiring terminals within the cabinet seamlessly with the lines at the remote Distributed Control System (DCS), ensuring smooth communication and control.
