MVR, which stands for mechanical vapor recompression, represents an innovative and energy-conserving technology designed to significantly diminish the need for external energy resources by cleverly reutilizing the secondary steam energy it produces. The fundamental principle at play here is that the secondary steam generated by the evaporator undergoes a transformation process. It is compressed using a highly energy-efficient steam compressor, thereby converting electrical energy into thermal energy. This process results in an increase in pressure and temperature of the secondary steam. Subsequently, the elevated temperature and pressure return this enriched steam back to the evaporator. Here, it seamlessly heats the materials, fosters evaporation, and ultimately achieves the recycling of the latent heat of vaporization of the secondary steam. This ingenious technology not only optimizes energy use but also champions a sustainable approach to industrial processes.
The DML series low temperature rise steam compressor is a marvel of engineering, primarily composed of various sophisticated components. These include the compressor body, which features critical elements such as the volute, impeller, main shaft, bearing housing, and seal. In addition to these, the compressor is equipped with a coupling, a motor, and an array of electric instruments, each meticulously designed to ensure seamless operation and precision in performance. This assembly of advanced technology works in harmony to deliver exceptional reliability and unparalleled efficiency.
3.3.1 Begin by gracefully positioning the compressor's robust base on the designated foundation. To ensure perfect leveling, strategically place wedge-shaped shims beneath the base.
Methodically alternate between two wedge-shaped irons, achieving ideal leveling. Securely spot weld these irons at 4 to 5 critical contact points for enduring stability.
Users should tailor the wedges to their specific needs, ensuring a finely finished contact surface for seamless interaction between the inclined planes.
The wedge iron's bearing prowess should be carefully managed, not exceeding a substantial 40Kg/cm2).
3.3.2 Employ a precision level to ascertain the unit’s balance. For the highest accuracy, the axial level should be within an impeccable 0.05/1000mm.
The horizontal level should remain precise at 0.10/1000mm for optimal efficacy.
3.3.3 Coupling alignment is crucial. Prior to commencement, ensure these pivotal preparations:
1) Ensure absolute safety by terminating the main power supply;
2) Carefully remove the coupling shield for uninhibited access;
3) Disassemble the diaphragm coupling's intermediate section with caution;
4) Verify that the motor installation surface is flawlessly flat, free from debris and obstructions;
5) Ensure motor bolt holes have ample size for bolt adjustments, allowing for seamless motor alignment;
6) Stock up on premium stainless steel gaskets to support the motor's foundation. These gaskets must be pristine and perfectly flat, avoiding long or thin variations for impeccable adjustment.
7) Utilize a highly accurate dial indicator or a laser alignment meter, with precision up to 0.01mm, to achieve precise alignment;
8) Arm yourself with a sturdy bracket, designed to support the dial indicator with unwavering stability;
9) Employ a hub mounting bracket, designed to mount a dial indicator at the wheel hub's edge, securing a probe on the compressor wheel hub's outer perimeter;
10) By deftly adjusting the bolts around the motor feet, achieve harmonious alignment of the compressor and motor center line, ensuring the maximum outer circle deviation is confined to a mere 0.05mm.
11) Conclude by firmly tightening the motor foot bolts, meticulously reassessing the coupling's outer circle and end face runout for precision.;
12) Post motor idle testing, seamlessly reinstall the coupling's intermediate section.
3.3.4 Upon perfecting the casing's alignment and levelness, securely tighten the anchor bolts. After mechanical operation, further reinforce by reassessing and re-tightening for optimal performance.
3.3.5 The impeller spins at high velocities; any intrusions can cause catastrophic damage. Ensure intake and outlet pipelines are impeccably clean and compliant with the system's steam corrosion standards, possibly integrating solid-liquid separation equipment for enhanced protection.
3.3.6 Securely install compressor intake and outlet pipes, accompanying them with pertinent pipeline accessories as per the PI diagram. External support brackets should bear the pipeline's weight, maintaining the compressor's integrity.
3.3.7 Once the primary fan and ancillary systems are installed and the concrete has fully set, confidently proceed with the compressor's operational testing.
