MVR, also known as mechanical vapor recompression, is an innovative and energy-efficient technology designed to minimize the reliance on external energy sources. It achieves this remarkable feat by capturing and reutilizing the energy from secondary steam it itself generates. At its core, the principle involves compressing the secondary steam produced by the evaporator using a highly efficient steam compressor. This process ingeniously converts electrical energy into thermal energy, elevating both the pressure and temperature of the secondary steam. This elevated steam then returns to the evaporator, where it efficiently heats the materials, leading to evaporation. Consequently, this cycle beautifully ensures the recycling of the latent heat of vaporization of the secondary steam, showcasing an elegant approach to energy conservation.
The oil-film high-speed direct drive steam compressor stands at the forefront of turbine equipment, incorporating a high-efficiency permanent magnet motor. Its ingeniously engineered main structure features an impeller seamlessly mounted at the shaft extension end of the motor. Additionally, the rotor benefits from direct support by an oil film bearing, enabling a direct drive mechanism powered by a high-speed motor. Notably, this advanced design eliminates the need for traditional speed-increasing boxes and couplings, marking a significant leap in efficiency and technological sophistication.
3.3.1 Begin with the seamless positioning of the compressor base onto the foundation. Enhance precision by placing wedge-shaped shims beneath, essential for leveling finesse.
Expertly position alternating wedge-shaped irons. Post leveling, secure them with precision spot welds at 4 to 5 strategic points. Remember, these wedges are crafted and installed by users, tailored to specific conditions.
Ensure meticulous surface finishing for even contact, as the inclined plane's bearing capacity shouldn’t surpass 40Kg/cm².
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Utilize a high-precision level to achieve perfect alignment. Adhere to unit leveling standards: axial level at 0.05/1000mm and horizontal level at 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Attain coupling perfection through precise centering. Prior to alignment, ensure the following prerequisites:
1) Disconnect the primary power source to secure safety;
2) Carefully remove the coupling shield to access the components;
3) Extract the diaphragm coupling's intermediate section for unobstructed access;
4) Scrutinize the motor installation plane, ensuring it's immaculate and devoid of obstructions;
5) Verify that motor bolt holes exceed bolt sizes to facilitate bolt loosening for motor adjustments;
6) Equip yourself with ample stainless steel gaskets for under-motor support, ensuring they’re impeccably clean and perfectly flat.
7) Employ a dial indicator or laser alignment meter with 0.01mm accuracy (customer-provided) for alignment precision;
8) Have on hand the specified bracket for dial indicator support as illustrated below;
9) Secure the motor wheel hub with an appropriate bracket, positioning a dial indicator probe on the compressor wheel hub's outer edge;
10) Fine-tune the adjustment bolts around the motor feet to align the compressor and motor center lines, aiming for a maximum deviation of just 0.05mm on the outer circle.
11) Conclude by firmly tightening the motor foot bolts, and meticulously reassess the coupling's outer circle and end face runout.;
12) Once the motor idling test is satisfactory, proceed by installing the coupling intermediate section.
3.3.4 Post-adjustment of casing 'levelness' and alignment, anchor bolts should be tightened. After operational tests, it is imperative to re-loosen and retighten them for optimal performance.
3.3.5 Protect the high-speed impeller from any solid or liquid intrusion, as these can cause irreversible damages. It's crucial to align the compressor’s inlet and outlet pipelines with the specified steam corrosion grade. Rectify any non-compliant pipelines and consider installing solid-liquid separation systems before the compressor inlet.
3.3.6 Proceed to install the compressor's inlet and outlet pipelines. Ensure all relevant pipeline accessories are incorporated as per the PI diagram. Support the connected pipelines with an independent bracket, avoiding any undue load on the compressor body.
3.3.7 Once the main fan and ancillary equipment are securely installed, and the concrete has set perfectly, initiate the compressor operation test to validate installation integrity.
