MVR, or Mechanical Vapor Recompression, represents a groundbreaking advancement in energy-saving technologies. This innovative approach significantly reduces the need for external energy by ingeniously reusing the secondary steam energy it generates. The fundamental principle involves the high-efficiency compression of secondary steam, produced by the evaporator, using a state-of-the-art steam compressor. This process efficiently transforms electrical energy into thermal energy, elevating the pressure and temperature of the secondary steam. This newly heated steam is then redirected back to the evaporator, where it effectively heats materials and promotes evaporation, thereby achieving a remarkable recycling of the latent heat of vaporization found in secondary steam.
The DML series Low Temperature Rise Steam Compressor is an engineering marvel, meticulously crafted from sophisticated components. At its core lies the compressor body, intricately designed with elements such as a volute, impeller, main shaft, bearing housing, and seals. These are seamlessly integrated with an advanced coupling, a powerful motor, and precision electric instruments. Together, they form a cutting-edge system renowned for its exceptional performance and reliability.
3.3.1 The compressor base is integrally placed on the foundation. Insert wedge-shaped shims beneath to ensure perfect leveling, ensuring stability and precision.
Position wedge-shaped irons alternately, achieving a perfectly leveled unit. Secure by spot welding at 4-5 points for unwavering sturdiness.
These custom wedges should be tailored to your specific setup, with a flawless contact surface to ensure even load distribution.
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Employ a precision level for alignment. The unit must maintain an impeccable axial level of 0.05/1000mm and a horizontal level of 0.10/1000mm for optimal performance.
level of the unit is 0.10/1000mm.
3.3.3 Center the coupling with utmost care. Prior to alignment, ensure the following prerequisites are met:
1) Disconnect the main power supply to ensure safety;
2) Remove the protective coupling shield with exacting precision;
3) Detach the diaphragm coupling's intermediate section for unobstructed access;
4) Meticulously check motor installation plane for any debris, ensuring pristine cleanliness;
5) Ensure motor bolt holes are suitably larger than bolts, facilitating easy adjustments for perfect alignment;
6) Prepare an ample supply of flawless stainless steel gaskets for motor support. Gaskets must be pristine, flat, and free of thin, lengthy extensions;
7) Utilize a high-precision dial indicator or laser alignment tool (customer provided) with 0.01mm accuracy for exact alignment;
8) Prepare a sturdy bracket to support the dial indicator, as illustrated below;
9) The motor wheel hub mounting bracket will facilitate dial indicator placement on the hub's edge, allowing precise measurement of the outer compressor hub edge;
10) By fine-tuning the adjustment bolts around the motor feet, align the compressor and motor center lines with utmost precision, ensuring a maximum deviation of 0.05mm. The motor shaft center must be slightly above the compressor's low-speed shaft, with a coupling end face deviation between 0.03~0.05mm.
11) Finalize by securely tightening the motor foot bolts, rigorously assessing the coupling's outer circle and end face runouts for flawless performance;
12) After performing a motor idling test, reinstall the coupling's intermediate section seamlessly.
3.3.4 Once the casing's levelness and alignment are perfected, firmly tighten the anchor bolts. Post-operation, bolts should be loosened and retightened to ensure continuous stability.
3.3.5 The impeller is a high-speed marvel; any foreign matter can cause catastrophic damage. Ensure all connected pipelines are impeccably clean and aligned with system steam corrosion standards, adding solid-liquid separation equipment if necessary to safeguard the impeller's integrity.
3.3.6 Attach compressor inlet and outlet pipes with precision, adhering to the PI diagram. Pipeline weight should be independently supported, ensuring compressor integrity remains uncompromised.
3.3.7 Once the main fan and auxiliary equipment are securely installed and the concrete has solidified, proceed with the compressor operation test, marking the final step of a seamless installation process.
