MVR, which stands for mechanical vapor recompression, is a groundbreaking energy-conserving technology designed to significantly minimize the dependency on external energy sources by ingeniously reutilizing the secondary steam energy it produces. The core principle revolves around compressing the secondary steam, which is generated by the evaporator, using a highly efficient steam compressor. This process converts electrical energy into thermal energy, elevating both the pressure and temperature of the secondary steam. This increase allows the reheated steam to return to the evaporator, subsequently heating the materials and causing further evaporation. Such an innovative cycle enables the effective recycling of the latent heat of vaporization of the secondary steam, embodying an exceptional advancement in sustainable energy usage.
The DM series Single-stage geard steam compressor is a marvel of engineering, featuring a comprehensive assembly that includes the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and anti-surge control system. This unit is celebrated for its compact structure, which not only saves space but also ensures that maintenance is straightforward and hassle-free. With its streamlined design, it epitomizes ease of use and reliability, making it an ideal choice for efficient energy management in various industrial applications.
3.3.1 To ensure optimal performance and stability, place the compressor base precisely on its foundation. Introduce wedge-shaped shims beneath the base to achieve perfect leveling of the unit.
Alternately arrange two wedge-shaped irons, carefully leveling the unit. Once alignment is confirmed, securely spot weld the wedge-shaped irons at 4-5 crucial points.
The user should manufacture and install the wedges according to specific conditions, ensuring the contact surface is finely finished for flawless inclined plane contact.
The wedge iron must have a bearing capacity not exceeding 40Kg/cm².2).
3.3.2 Achieve precise leveling using a level. The unit's leveling specifications are stringent: axial level at 0.05/1000mm and horizontal level at 0.10/1000mm.
3.3.3 Perfect coupling alignment is crucial. Prior to this procedure, ensure the following essential conditions are met:
1) Power down the main electrical supply completely;
2) Carefully remove the coupling shield;
3) Detach the diaphragm coupling's intermediate section;
4) Verify the motor installation surface flatness to ensure it's free from foreign materials;
5) Ensure motor bolt holes surpass bolt sizes to allow bolt loosening for motor adjustments;
6) Prepare ample, flat stainless steel gaskets to support the motor feet, ensuring they are free from any attachments. Avoid inserting long, thin gaskets between the motor and the base.
7) Utilize a dial indicator or laser alignment meter with 0.01mm accuracy, to be sourced by the customer;
8) Assemble the essential bracket for dial indicator support, as illustrated below;
9) Employ the motor wheel hub mounting bracket to affix the dial indicator on the hub's edge, placing the probe on the compressor wheel hub's outer edge;
10) Fine-tune motor foot adjustment bolts to align the compressor and motor center line ideally. Ensure maximum deviation of the outer circle is within 0.05mm, and the coupling end face is 0.03~0.05mm higher.
11) Securely tighten motor foot bolts, then meticulously review coupling's outer circle runout and end face runout.;
12) Reinstall the coupling intermediate section after a satisfactory motor idling test.
3.3.4 Post alignment, firmly secure all anchor bolts. After trial operations, loosen and re-tighten bolts to ensure steadfast mechanical integrity.
3.3.5 The impeller operates at high speeds; any solid or liquid incursion can irreparably damage the compressor. Ensure inlet and outlet pipelines are pristine and compliant with the system's steam corrosion standards. Non-compliant pipelines require immediate rectification.Incorporate solid-liquid separation equipment, such as gas scrubbers or sedimentation tees, before the compressor inlet's straight pipe for enhanced protection.
3.3.6 During installation, affix compressor inlet and outlet pipes with PI diagram-conforming accessories. Ensure pipeline weight is supported by an independent bracket, not the compressor body.
3.3.7 Once the majestic main fan and its essential ancillary equipment have been meticulously installed and the concrete has reached its full solidity, the stage is perfectly set for conducting the compressor operation test.
3.3.8 The electric control cabinet of the compressor should find its home within a strategic 5m radius of the compressor. The connection journey from the compressor to this vital control hub should be elegantly completed through an underground threading pipe. Once the electric control cabinet is securely stationed, seamlessly connect the wiring terminals inside with the lines at the remote DCS, ensuring optimal performance and coordination.
