MVR, standing for Mechanical Vapor Recompression, is a groundbreaking energy-conserving technology designed to significantly reduce the reliance on external energy sources. It achieves this by ingeniously reutilizing the secondary steam energy that it generates. At its core, the technology's fundamental principle lies in the transformation of the secondary steam produced by the evaporator. This steam is skillfully compressed using a high-energy-efficiency steam compressor, effectively translating electrical energy into thermal energy. As a result, the pressure and temperature of the secondary steam are elevated, enabling this energy-rich steam to return to the evaporator, where it efficiently heats the materials and induces evaporation. This cycle ingeniously ensures the recycling of the latent heat of vaporization from the secondary steam, optimizing energy use and enhancing sustainability.
The DM series Single-stage Geared Steam Compressor is an engineering marvel, featuring a sophisticated design that includes the compressor body, coupling, gearbox, lubrication system, motor, electronic instrumentation, and an advanced anti-surge control system. Boasting a compact structure, it is not only space-efficient but also remarkably easy to maintain, ensuring reliability and longevity. Its innovative design makes it an ideal choice for seamless and efficient operations.
3.3.1 The compressor base should be positioned seamlessly on the designated foundation. Carefully place wedge-shaped shims beneath the base to achieve perfect leveling of the unit. Use alternating pairs of wedge-shaped irons, ensuring they are properly spot-welded at 4 to 5 strategic points.
Ensure the wedge-shaped irons are manufactured and installed by you, tailored to the specific scenario encountered. The contact surface must be flawlessly finished, allowing for even contact on the inclined plane. Remember, maintain a bearing capacity not exceeding 40Kg/cm.
plane. The design demands the wedge be tailored to the unique conditions. The contact surface must ensure a seamless connection, offering a perfect fit.
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Utilize a reliable level to achieve impeccable accuracy. The unit's leveling requirements are strict: the axial level must be 0.05/1000mm, while the horizontal level should be 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Precision alignment of the coupling is crucial. Before initiating the alignment process, ensure the following prerequisites are fulfilled:
1) Securely turn off the main power supply;
2) Carefully remove the protective coupling shield;
3) Detach the diaphragm coupling intermediate section for easy access;
4) Thoroughly inspect the motor installation plane for cleanliness, ensuring no foreign particles, dirt, or debris;
5) The motor bolt holes should be spacious enough to accommodate bolt adjustments, allowing for easy motor realignment;
6) Ample stainless steel gaskets should be prepared to adequately support the motor's foot. These gaskets must be pristine, devoid of any attachments, and maintain a flat profile. Avoid using elongated or thin gaskets for adjustments;
7) Employ a high-precision dial indicator or laser alignment meter with an accuracy of 0.01mm, which should be provided by the customer;
8) Have the necessary bracket ready to support the dial indicator, as depicted in the accompanying illustration;
9) A specifically designed motor wheel hub mounting bracket is essential for positioning a dial indicator on the hub's edge, ensuring precise measurement on the compressor wheel hub's outer edge;
10) Carefully adjust the bolts around the motor feet to align the compressor and motor center lines, aiming for an outer circle deviation of no more than 0.05mm. Ensure the motor shaft center line is slightly elevated compared to the compressor's low-speed shaft center line, with a coupling end face deviation between 0.03~0.05mm;
11) Once alignment is achieved, firmly tighten the motor foot bolts, then meticulously check the coupling's outer circle runout and end face runout.;
12) After a successful motor idling test, reinstall the coupling intermediate section, ensuring everything is secure and ready for operation.
3.3.4 Once the casing's 'levelness' and alignment are perfected, securely tighten the anchor bolts. After conducting the mechanical operation or trial operation, loosen and retighten the bolts to ensure optimal stability.
3.3.5 The impeller, being a high-speed rotating component, requires utmost care. Any solid or liquid intrusion could cause irreversible damage to the compressor. It is imperative to ensure the pipelines connected to the compressor are pristine, adhering to the steam corrosion grade standards of the system. Pipelines not meeting these criteria must undergo rectification.To safeguard the system, consider incorporating solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the straight pipe at the compressor inlet.
3.3.6 Seamlessly install the compressor's inlet and outlet pipes. Follow the PI diagram for appropriate pipeline accessories installation. Ensure the pipeline's weight is supported by a separate bracket, not by the compressor body itself, for structural integrity.
3.3.7 Once the majestic main fan and its supportive ancillary equipment are securely in place and the robust concrete foundation has fully solidified, you can proceed with the exciting phase of conducting the compressor operation test. This marks a crucial step in ensuring optimal performance and reliability.
3.3.8 Position the electric control cabinet of the compressor strategically within a 5-meter radius of the compressor itself. Ensure a seamless connection by running the wiring through protective threading pipes that are routed underground, safeguarding against external elements. Once the electric control cabinet is perfectly situated, skillfully connect the wiring terminals inside the cabinet to the lines at the remote DCS to achieve an efficient and synchronized system.
