MVR, which stands for Mechanical Vapor Recompression, represents a cutting-edge energy-saving technology that significantly reduces the need for external energy by ingeniously reutilizing the secondary steam energy it generates. The core principle of MVR involves the compression of secondary steam produced by the evaporator using a highly efficient steam compressor. This process masterfully converts electrical energy into thermal energy, resulting in an increase in both the pressure and temperature of the secondary steam. The elevated temperature then cycles back into the evaporator, efficiently heating the materials and generating evaporation to achieve the remarkable recycling of the latent heat of vaporization from the secondary steam.
The DM Series Single-stage Geared Steam Compressor, a marvel of engineering, primarily comprises the compressor body, coupling, gearbox, lubrication system, motor, electronic instruments, and an advanced anti-surge control system. Designed with a compact structure, this compressor ensures ease of maintenance while delivering unparalleled performance efficiency. Its thoughtful design and robust components make it an ideal choice for any setting requiring reliable and consistent operation.
3.3.1 Begin by securely placing the compressor base onto the foundation, ensuring stability with wedge-shaped shims for precise leveling.
Position two wedges in alternating fashion. Once perfectly leveled, spot weld at 4-5 points for enduring steadiness. Custom-fabricate
the wedges as per actual conditions with a finely finished contact surface, ensuring even and secure contact.
The wedge must not exceed a remarkable support capacity of 40Kg/cm2.)
3.3.2 Utilize a level to achieve the utmost precision. The axial level precision: an impressive 0.05/1000mm; horizontal precision:
a notable 0.10/1000mm.
3.3.3 Ensure coupling is perfectly centered, adhering to the following preparatory steps:
1) Securely disconnect the main power supply;
2) Dismantle the protective coupling shield;
3) Extract the diaphragm coupling's intermediate section;
4) Verify the motor installation surface for cleanliness and absence of debris;
5) Ensure motor bolt holes are adequately larger, allowing bolt loosening for motor adjustment;
6) Have ample stainless steel gaskets ready to support the motor foot, ensuring flatness and cleanliness—avoid long, slender gaskets for this purpose;
7) Employ a dial indicator or superior laser alignment meter with 0.01mm accuracy (to be supplied by the customer);
8) Have the appropriate bracket prepared for dial indicator support as illustrated below;
9) Mount the dial indicator on the motor wheel hub bracket, positioning its probe on the compressor wheel hub's outer edge;
10) Skillfully align the motor and compressor centerlines via adjustment bolts, maintaining a maximum deviation of 0.05mm with the motor shaft center line slightly elevated. Ensure coupling end face deviation is maintained between 0.03~0.05mm;
11) Securely fasten the motor foot bolts and re-examine both outer circle and end face runouts for absolute precision.;
12) Conclude by reinstalling the coupling intermediate section post-motor idle test.
3.3.4 Upon achieving impeccable levelness and alignment, tighten anchor bolts. Post mechanical operation, loosen and retighten for optimal performance.
3.3.5 The impeller, a high-speed dynamic component, demands absolute cleanliness to prevent irreversible compressor damage. Ensure inlet and outlet pipelines are pristine and compliant with steam corrosion specifications. Non-compliant pipelines require immediate rectification.Incorporate solid-liquid separation devices (like a gas scrubber or sedimentation tee) before the compressor inlet's straight pipe for optimal protection.
3.3.6 Proceed with the installation of compressor inlet and outlet pipes. Align pipelines with the PI diagram and ensure they are supported independently of the compressor body to maintain structural integrity.
3.3.7 Upon the complete installation of the main fan along with its ancillary equipment and the full solidification of the concrete foundation, it is time to proceed with the compressor operation test. This step is crucial for ensuring the optimal functionality and reliability of your Reliable Steam Compressor designed specifically for consistent pharmaceutical wastewater treatment results. Trust in the outstanding quality provided by NANTONG DART-RICH FAN CO., LTD for all your precise operational needs.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within a 5-meter radius of the compressor itself. This proximity allows for efficient management and control. To ensure safe and reliable connectivity, the wiring from the compressor to the electric control cabinet must be carefully routed through threading pipes, which should be installed underground for enhanced protection. Once the electric control cabinet is securely in place, seamlessly link the wiring terminals inside it with the remote DCS lines, ensuring a robust and effective connection to maintain the exceptional performance standards of our Reliable Steam Compressor, a flagship offering by NANTONG DART-RICH FAN CO., LTD.
