MVR, short for Mechanical Vapor Recompression, represents a groundbreaking energy-saving technology that significantly reduces the need for external energy sources. It achieves this by ingeniously reutilizing the secondary steam energy it generates. The core principle involves the secondary steam produced by the evaporator being expertly compressed using a highly efficient steam compressor. This process transforms electrical energy into thermal energy, increasing the pressure and temperature of the secondary steam. The elevated temperature subsequently returns the steam to the evaporator, heating the materials and inducing evaporation. This sophisticated cycle allows for the recycling of the latent heat of vaporization of the secondary steam, promoting remarkable energy efficiency.
The DML series low temperature rise steam compressor is meticulously engineered, consisting primarily of a compressor body, which includes vital components such as the volute, impeller, main shaft, bearing housing, and seal. Additionally, it incorporates a coupling, motor, and state-of-the-art electric instruments. This comprehensive design ensures optimal performance and reliability, making it an ideal choice for various industrial applications.
3.3.1 Delight in the seamless installation of the compressor base as it is expertly integrated onto the foundation. Introduce precision and stability with wedge-shaped shims beneath the base, designed to impeccably adjust the level of the unit.
Effortlessly alternate two wedge-shaped irons post-leveling. Securely spot weld the irons at 4-5 strategic points, for a robust and reliable installation.
Craft the wedge with precision, customized to the user's specific situational needs. Ensure impeccable contact with a meticulously finished surface for uniform engagement of the inclined plane.
plane, maintaining a sturdy bearing capacity of no more than 40Kg/cm2).
3.3.2 Achieve flawless leveling using a level. The unit's axial level should be a precise 0.05/1000mm, while the horizontal level remains an exact 0.10/1000mm, ensuring peak performance.
level of the unit is 0.10/1000mm.
3.3.3 Perfectly align the coupling. Before commencing, ensure these prerequisites are impeccably met:
1) Ensure total safety by shutting off the main power supply;
2) Remove the coupling shield expertly;
3) Detach the diaphragm coupling intermediate section with precision;
4) Assure an immaculate motor installation plane by verifying the absence of debris, dirt, and attachments;
5) The motor bolt hole should be appropriately larger than the bolt size, facilitating motor adjustment by loosening the bolt effortlessly;
6) Have an ample supply of flawless stainless steel gaskets to support the motor footing. Choose flat gaskets only, avoiding long, slender ones for a steadfast adjustment;
7) Utilize a dial indicator or a laser alignment meter, boasting an accuracy of 0.01mm, a testament to precision engineering;
8) Readily prepare a bracket to strongly support the dial indicator as expertly demonstrated below;
9) Employ the motor wheel hub mounting bracket to skillfully mount a dial indicator at the wheel hub's edge, positioning the probe on the compressor wheel hub's outer edge with finesse;
10) Attain the ultimate alignment by adjusting the motor feet's bolts such that the compressor and motor center line align. Limit the outer circle deviation to an impressive 0.05mm, with the motor shaft center line elevated over the compressor's low-speed shaft center line, and a coupling end face precision of 0.03~0.05mm;
11) Conclude by firmly tightening the motor foot bolts, followed by a thorough review of the coupling's outer circle and end face runout for a flawless finish;
12) Finally, with the motor's idling test completed, reinstall the coupling intermediate section.
3.3.4 Post-adjustment of the alignment and 'levelness' of the casing, secure the anchor bolts. Post mechanical operation or trial, loosen and retighten the bolts to ensure steadfast stability.
3.3.5 The impeller's high-speed rotation demands vigilance; any solid or liquid intrusion can irreversibly damage the compressor. Meticulously ensure that the inlet and outlet pipelines are pristine and adhere to steam corrosion grade standards. Rectify any non-compliant pipelines promptly. Enhance protection by installing solid-liquid separation equipment (gas scrubber or sedimentation tee) preceding the compressor inlet's straight pipe.
3.3.6 Elegantly install the compressor's inlet and outlet pipes. Follow the PI diagram to precisely fit import and export pipelines with relevant accessories. Ensure that the pipeline's weight is independently supported by an additional bracket rather than the compressor body.
3.3.7 Once the main fan and its auxiliary equipment are expertly installed and the concrete has solidified completely, proceed with the compressor operation test to ensure peak functionality.
