MVR, which stands for Mechanical Vapor Recompression, represents a groundbreaking and energy-efficient technology designed to significantly cut down on external energy requirements. This innovative approach achieves remarkable energy savings by ingeniously repurposing the secondary steam energy it generates. At the heart of MVR's operation lies a fundamental principle: the secondary steam produced by the evaporator undergoes compression through a high-efficiency steam compressor. This compression process adeptly transforms electrical energy into thermal energy, leading to an elevation in both pressure and temperature of the secondary steam. This elevation allows the secondary steam to be cycled back to the evaporator, where it effectively heats the materials and induces further evaporation. In this way, MVR ingeniously recycles the latent heat of vaporization of the secondary steam, maximizing energy utilization and minimizing waste.
The DML series low temperature rise steam compressors exemplify cutting-edge engineering. These advanced compressors are meticulously crafted and consist of several key components: a robust compressor body, which includes the volute, impeller, main shaft, bearing housing, and seal; alongside a reliable coupling, motor, and an array of electric instruments. Each component is designed with precision, ensuring optimal performance, durability, and efficiency for a wide range of industrial applications.
3.3.1 Begin by positioning the compressor base seamlessly onto the foundation. Employ wedge-shaped shims beneath the base to achieve impeccable leveling of the unit.
Strategically place two alternately arranged wedge-shaped irons. Upon precise leveling, employ spot welding on the irons at 4 to 5 strategic points. Remember,
the user must craft and install these wedges tailored to the specific situation. Ensure the contact surfaces are exquisitely finished for even contact on the
inclined plane, adhering to a robust bearing capacity not exceeding 40Kg/cm2).
3.3.2 Employ a level to ascertain perfect alignment. The unit's alignment standards: an axial level precision of 0.05/1000mm and a horizontal level of
0.10/1000mm, ensuring optimal performance.
3.3.3 Achieve perfect coupling alignment. Prior to commencing this crucial process, ensure the following requirements are meticulously met:
1) Power down the main supply;
2) Detach the coupling shield;
3) Extract the diaphragm coupling's intermediate section;
4) Inspect the motor installation plane to confirm absence of debris, dust, and extraneous materials;
5) Ensure the motor bolt holes exceed the bolt size, allowing for easy loosening and motor adjustment;
6) Prepare ample stainless steel gaskets for the motor's footing. Ensure these gaskets are pristine and exquisitely flat. Avoid inserting long, slender gaskets between the motor and the base for fine-tuning;
7) Utilize either a dial indicator or a state-of-the-art laser alignment tool with a precision of 0.01mm (to be arranged by the client);
8) Equip yourself with a bracket to support the dial indicator, as depicted in the accompanying figure;
9) Employ a motor wheel hub mounting bracket to situate a dial indicator on the wheel hub's edge, placing the probe along the compressor wheel hub's outer edge;
10) Through adept adjustment of motor foot bolts, align the compressor and motor center line almost perfectly (or as guided by specific instructions), ensuring a maximum outer circle deviation of 0.05mm. The motor shaft center line should ideally be elevated above the compressor's low-speed shaft center line. Maintain a coupling end face deviation of 0.03~0.05mm;
11) Conclusively tighten the motor foot bolts and reassess any deviations in the outer circle runout and end face runout of the coupling;
12) Following a successful motor idling test, proceed to install the coupling's intermediate section.
3.3.4 Post-adjustment of casing "levelness" and alignment, secure the anchor bolts. Following mechanical or trial operations, loosen and re-tighten the bolts to ensure stability.
3.3.5 The impeller, a high-speed marvel, must remain devoid of any solid or liquid intrusions to prevent irreversible compressor damage. It is imperative that the connected inlet and outlet pipelines are pristine and meet the steam corrosion standards set by the system. Pipelines falling short of these standards must undergo rectification. Consider integrating solid-liquid separation solutions, like a gas scrubber or sedimentation tee, just before the compressor inlet's straight pipe.
3.3.6 Proceed to install the compressor's inlet and outlet pipes. Ensure import and export pipelines are fitted with appropriate accessories as depicted in the PI diagram. The pipeline connecting to the compressor should be independently supported by an auxiliary bracket, ensuring no weight burden on the compressor itself.
3.3.7 Once the main fan and its ancillary equipment are meticulously installed and the concrete has reached its full strength, you can proceed to conduct the compressor operation test. This will ensure that all systems are operating flawlessly and ready for optimal performance.
3.3.8 For optimal setup and efficiency, the electric control cabinet of the compressor should be strategically positioned within a 5-meter radius of the compressor. The wiring connecting the compressor to this cabinet should be securely threaded through pipes and placed underground to ensure safety and durability. Once the electric control cabinet is properly situated, you should seamlessly link the wiring terminals within the cabinet to the lines at the remote DCS to establish a robust and reliable operation network.
