MVR, an acronym for Mechanical Vapor Recompression, is an innovative energy-saving technology designed to dramatically minimize the reliance on external energy sources by ingeniously reutilizing the secondary steam energy it generates. The fundamental principle of MVR technology involves compressing the secondary steam, produced by the evaporator, using a highly efficient steam compressor. This process adeptly transforms electrical energy into thermal energy, boosting both the pressure and temperature of the secondary steam. The elevated temperature then channels the enhanced steam back to the evaporator, effectively heating the materials, generating further evaporation, and thus, achieving a sophisticated recycling of the latent heat of vaporization present in the secondary steam. This cutting-edge technology embodies a perfect blend of efficiency and sustainability.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, composed of several critical components, including the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. This exceptional compressor boasts a compact design, making it incredibly convenient for maintenance purposes while ensuring optimal performance. Every aspect of its construction is meticulously crafted to deliver reliability and efficiency, providing a seamless and robust solution for your steam compression needs.
3.3.1 Start by positioning the compressor base securely on the foundation. Use wedge-shaped shims beneath the base to meticulously adjust and level the unit.
Place two wedge-shaped irons in an alternating fashion. Once the unit is perfectly leveled, spot weld the wedge-shaped irons at 4 to 5 strategic points for enhanced stability.
These wedges must be custom-manufactured and installed by the user, tailored to the actual conditions. Ensure the contact surfaces are impeccably finished for even interface on the inclined plane.
plane. It is crucial that the load-bearing capacity of each wedge iron is kept below 40Kg/cm2).
3.3.2 Employ a precise level to ascertain exact horizontality. The unit's leveling precision is impeccable: the axial level should be 0.05/1000mm, while the horizontal level should be 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Achieving coupling alignment is paramount. Prioritize the following preparatory steps before commencing alignment:
1) Ensure the main power supply is completely turned off for safety;
2) Dismantle the coupling shield carefully;
3) Detach the diaphragm coupling's intermediate section with precision;
4) Verify that the motor installation plane is flawlessly flat, free from debris, dirt, and any unwanted attachments;
5) The motor bolt holes should be larger than the bolts themselves, allowing for easy adjustments by loosening the bolts to reposition the motor.
6) Have a sufficient supply of pristine stainless steel gaskets to fully support the motor's feet. Gaskets should be flawlessly flat and devoid of any attachments.
7) Utilize a high-precision dial indicator or a laser alignment meter with an astounding accuracy of 0.01mm, which must be provided by the customer.
8) Prepare a sturdy bracket to accommodate the dial indicator as illustrated in the accompanying figure.
9) Fasten the motor wheel hub mounting bracket securely to position a dial indicator on the hub's edge, ensuring the probe makes contact with the outer edge of the compressor wheel hub.
10) Adjust the motor's positioning bolts strategically, so the compressor and motor center lines align seamlessly. The maximum outer circle deviation is 0.05mm, the motor shaft should be slightly higher than the compressor's low-speed shaft center. Coupling end face should range from 0.03 to 0.05mm.
11) Securely tighten the motor foot bolts. Rigorously review the coupling's outer circle runout and end face runout to ensure perfect alignment.;
12) Following a successful motor idling test, reattach the coupling's intermediate section with precision.
3.3.4 Once the casing's levelness and alignment are adjusted, tighten the anchor bolts firmly. After a mechanical or trial operation, loosen and retighten bolts to ensure optimal security.
3.3.5 The impeller rotates at high speed; therefore, preventing solid or liquid entry is critical as they can cause irreversible damage. Ensure inlet and outlet pipelines are spotless and adhere to the system's steam corrosion grade standards. Rectify any pipelines that fall short of these stringent standards.Consider installing solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, to proactively protect the compressor inlet.
3.3.6 Proceed to install compressor inlet and outlet pipes in accordance with the PI diagram. All connecting pipelines must be supported by independent brackets, ensuring no weight is borne by the compressor body itself.
3.3.7 Once the main fan, along with its supportive apparatus, is meticulously installed and the concrete thoroughly solidifies, you are poised to initiate the compressor's operation test. This step marks the beginning of seamless performance and efficiency!
3.3.8 Position the compressor's electric control cabinet within a convenient 5-meter range from the compressor. Skillfully thread the wiring through an underground conduit to connect the compressor to the control cabinet. Once the cabinet is securely in place, ensure that the wiring terminals in the electric control cabinet are seamlessly linked to the remote DCS lines for optimal functionality.
