MVR, an industry-leading acronym for Mechanical Vapor Recompression, offers an innovative and energy-efficient technology designed to significantly decrease external energy needs. By ingeniously repurposing the secondary steam energy it produces, MVR maximizes energy conservation. The pioneering concept behind this technology involves the clever compression of secondary steam generated by the evaporator. This process employs a high-efficiency steam compressor, which skillfully transforms electrical energy into thermal energy. As a result, there is an impressive increase in both pressure and temperature of the secondary steam. This heightened temperature then allows the steam to be redirected back to the evaporator, where it efficiently heats materials, inducing further evaporation. Consequently, this remarkable cycle enables the effective recycling of the latent heat of vaporization of secondary steam, paving the way for exceptional energy savings.
The DML series low temperature rise steam compressor is a masterpiece of engineering, comprising several key components: the robust compressor body, which includes a volute, impeller, main shaft, bearing housing, and seal, all working in flawless harmony. This high-performance compressor also features a precision coupling, a powerful motor, and advanced electric instruments. Together, these elements create a seamless system, meticulously designed to deliver superior performance and enhanced control, setting new standards in energy efficiency and operational excellence.
3.3.1 Begin by placing the compressor base seamlessly onto its foundation. Insert wedge-shaped shims beneath the base to ensure perfect leveling.
Utilize alternating wedge-shaped irons for precise leveling. Post-alignment, secure the wedges with 4-5 spot welds for stability.
Craft and install wedges tailored to your specific installation environment. Ensure the contact surface is finely finished for even distribution.
Maintain the load-bearing capacity of the wedge iron under 40Kg/cm² for optimal durability.2).
3.3.2 Employ a level to fine-tune the alignment. The unit's axial level should be 0.05/1000mm, with a horizontal precision of 0.10/1000mm.
These specifications ensure smooth and efficient operation.
3.3.3 Center the coupling with meticulous precision. Prior to alignment, ensure the following prerequisites are fulfilled:
1) Safely disconnect the main power supply.
2) Carefully remove the coupling shield to expose the area.
3) Detach the diaphragm coupling's intermediate segment for better access.
4) Inspect the motor's installation surface for cleanliness, removing any debris or obstructions.
5) Allow for bolt adjustment by ensuring motor bolt holes are larger than the bolts.
6) Have ample flat, stainless steel gaskets ready for motor footing. Avoid using elongated or thin gaskets for adjustments.
7) Utilize a high-precision dial indicator or a laser alignment meter (customer-supplied) for accuracy.
8) Construct a support bracket for the dial indicator as referenced in the accompanying diagram.
9) Fit a dial indicator on the motor hub's edge using the designated mounting bracket.
10) Align the compressor and motor center lines with finesse, using adjustment bolts to achieve minimal deviation—outer circle deviation at 0.05mm.
11) Post alignment, secure the motor foot bolts and verify both the outer circle and end face for runout consistency.;
12) Conclude by installing the coupling's intermediate section following a successful motor idle test.
3.3.4 Secure the anchor bolts post-leveling and alignment adjustments. After any operational trials, loosen and retighten bolts for reinforced security.
3.3.5 The impeller's high-speed rotation demands pristine conditions; any foreign substances can cause catastrophic damage. Ensure cleanliness and adhere to steam corrosion standards for all connected pipelines. Implement solid-liquid separation devices to safeguard your system.
3.3.6 Attach the compressor's inlet and outlet pipes, ensuring proper installation with PI diagram-relevant accessories. Support the pipeline independently to avoid placing undue stress on the compressor.
3.3.7 Following the successful installation of the main fan and all associated ancillary equipment, and once the concrete has achieved complete solidification, it's time to embark on the compressor operation test. This crucial step ensures that the Low Temperature Rise Fan with Speed Regulation for Enhanced Control is ready to deliver its exceptional performance, embodying the hallmark of excellence by NANTONG DART-RICH FAN CO.,LTD.
3.3.8 Ensure the electric control cabinet of the compressor is strategically positioned within a 5-meter radius of the compressor. This proximity facilitates seamless connectivity, achieved through underground threading pipes, integrating the compressor directly to the electric control cabinet. Once the cabinet is securely in position, the next step is to meticulously connect the wiring terminals within, establishing a robust link with the remote DCS, thereby guaranteeing reliable and efficient operational control.
