MVR, an acronym for mechanical vapor recompression, is a cutting-edge, energy-conservation technology that significantly reduces the need for external energy by masterfully re-utilizing the energy generated by secondary steam. The fundamental principle of MVR involves the secondary steam produced by the evaporator being compressed with a high-efficiency steam compressor. This brilliant process ingeniously converts electrical energy into thermal energy, thereby elevating the pressure and temperature of the secondary steam. Consequently, this heightened temperature allows the secondary steam to return to the evaporator, where it heats the materials and induces evaporation, thus exquisitely recycling the latent heat of vaporization of the secondary steam.
The DM series Single-stage geared steam compressor is a marvel of engineering that predominantly comprises the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. Its design is a testament to compact ingenuity, offering a structure that is both space-efficient and remarkably easy to maintain. This fusion of practicality and sophistication ensures optimal performance and longevity.
3.3.1 Position the compressor base integrally upon the foundation and place wedge-shaped shims beneath to ensure a perfectly leveled unit. These shims allow for precise adjustment and are critical for optimal alignment.
Use two alternating wedge-shaped irons for meticulous leveling. Once achieved, secure them with spot welds at 4 to 5 strategic points. It is essential that these wedges be user-manufactured to meet the specific site conditions, ensuring flawless contact surfaces.
The wedge's contact surface must be finished for impeccable contact on inclined planes. The bearing capacity must not exceed the robust limit of 40Kg/cm, ensuring stability.
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Employ a precise level to achieve exact alignment. The stringent leveling criteria dictate that the unit's axial level be 0.05/1000mm, while its horizontal level should maintain 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Center the coupling with absolute precision. Before aligning, ensure the following preparatory steps are fulfilled:
1) Ensure the primary power supply is completely switched off to guarantee safety;
2) Detach the coupling shield to expose critical components for alignment;
3) Carefully remove the diaphragm coupling's intermediate section;
4) Examine the motor installation plane to confirm it is free of debris, dirt, and unwanted attachments;
5) Motor bolt holes must exceed bolt sizes to accommodate adjustments, facilitating easy loosening for precise motor adjustment;
6) Ensure ample, spotless stainless steel gaskets are available to support the motor's base. Avoid long, thin gaskets for adjustments between the motor and base;
7) Utilize a dial indicator or laser alignment meter, boasting a remarkable accuracy of 0.01mm, personally provided by the customer;
8) Secure a bracket for the dial indicator, as depicted in the diagram below, for optimal support;
9) Employ the motor hub mounting bracket to attach a dial indicator at the wheel hub's edge, positioning the probe accurately on the compressor hub's outer edge;
10) Adjust the bolts surrounding the motor feet to align the compressor and motor center lines meticulously. The outer circle's deviation must not exceed 0.05mm, while the coupling's end face should remain between 0.03~0.05mm.
11) Securely fasten the motor foot bolts and reevaluate the outer circle and end face runout of the coupling for assurance.;
12) Reinstall the coupling's intermediate section post motor idling test to ensure seamless operation.
3.3.4 Once alignment and 'levelness' adjustments are confirmed, firmly tighten the anchor bolts. After initial mechanical operation or trial runs, loosening and retightening may be necessary to ensure optimal performance.
3.3.5 The impeller, a high-speed marvel, is sensitive to any intrusive solid or liquid which may cause irreversible damage. Thus, maintaining clean and system-compliant inlet and outlet pipelines is imperative. Pipelines falling short of standards must be rectified immediately to prevent complications.For added safety, consider integrating solid-liquid separation apparatus, such as a gas scrubber or sedimentation tee, preceding the compressor inlet's straight pipe.
3.3.6 Execute the precise installation of compressor inlet and outlet pipes. Follow the PI diagram meticulously for conduit accessories. Ensure pipelines connected to the compressor have independent support brackets to avoid undue strain on the compressor body.
3.3.7 Once the main fan along with its ancillary equipment is seamlessly installed and the concrete foundation has reached full solidity, it is time to smoothly transition into the compressor operation test. This ensures optimal performance and reliability.
3.3.8 The electric control cabinet for the compressor must be strategically positioned within a 5-meter radius of the compressor itself. Secure and efficient wiring from the compressor to the control cabinet should be meticulously installed using threaded pipes, which must be carefully routed underground for protection. Once the electric control cabinet is expertly positioned, connect the wiring terminals within the cabinet to the lines at the remote Distributed Control System (DCS) for seamless integration and superior operational efficiency.
