MVR, which stands for Mechanical Vapor Recompression, is a groundbreaking energy-saving technology designed to significantly cut down the need for external energy sources. This innovation achieves its efficiency by ingeniously reutilizing the secondary steam energy it produces. The fundamental principle of MVR involves compressing secondary steam, generated by the evaporator, using a highly efficient steam compressor. This process ingeniously transforms electrical energy into thermal energy, elevating the pressure and temperature of the secondary steam. The elevated temperature allows the steam to return to the evaporator, where it heats materials and induces further evaporation. This cycle effectively recycles the latent heat of vaporization, ensuring optimal energy utilization and remarkable sustainability.
The DM series Single-stage Geared Steam Compressor is a state-of-the-art solution that primarily comprises a robust compressor body, coupling, gearbox, lubrication system, motor, electric instrumentation, and an advanced anti-surge control system. Its design boasts a compact structure, making it exceptionally easy to maintain. This cutting-edge compressor offers unparalleled efficiency and reliability, ensuring seamless operation across various applications.
3.3.1 Begin with situating the compressor's base securely onto the foundation. Introduce wedge-shaped shims beneath the base, optimizing for perfect leveling of the unit. This meticulous placement ensures stability and performance excellence.
Place these wedge-shaped irons alternatively, achieving a flawless level. Once aligned, strategically spot weld the wedge irons at 4 to 5 points. Each wedge is crafted and installed by the user, tailored to the actual site conditions, ensuring a seamless and even contact on inclined planes.
The created wedge must reflect precision, with its contact surface polished for uniform engagement. It's critical that the bearing capacity remains under 40Kg/cm² to ensure optimal performance.
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm².2).
3.3.2 Utilize a level to ascertain perfect alignment. The unit's axial level must be 0.05/1000mm, with a horizontal level precision of 0.10/1000mm, ensuring unwavering stability and operational efficiency.
level of the unit is 0.10/1000mm.
3.3.3 Achieving coupling centering is paramount. Before commencing alignment, adhere to these crucial prerequisites:
1) Disengage the main power supply; ensuring safety first.
2) Detach the coupling shield, laying the groundwork for precise adjustments;
3) Remove the diaphragm coupling intermediate section for an unobstructed alignment process.
4) Thoroughly check the motor installation plane's flatness, ensuring it is free from any debris, dirt, or attachments that might hinder performance;
5) Ensure the motor's bolt holes exceed the bolt sizes, allowing bolts to be loosened effectively for motor adjustments;
6) Stock sufficient stainless steel gaskets to cradle the motor's foot. These gaskets must be immaculately clean, flat, and robust - avoiding elongated, thin gaskets for adjustment purposes.
7) Equip yourself with a precision dial indicator or a laser alignment meter with an accuracy of 0.01mm, ensuring impeccable alignment.
8) Have ready a supportive bracket for the dial indicator as illustrated below; this ensures precision and stability during alignment.
9) The motor wheel hub mounting bracket facilitates the placement of the dial indicator on the wheel hub's edge, while its probe measures the compressor hub's outer edge with precision;
10) By skillfully adjusting the bolts encircling the motor feet, align the motor and compressor center lines. Aim for a maximum deviation in the outer circle of 0.05mm, keeping the motor shaft center slightly above the compressor's low-speed shaft center line, with coupling end face deviation within 0.03~0.05mm.
11) Secure the motor foot bolts firmly. Conduct a meticulous review of both outer circle runout and coupling end face runout to ensure precise alignment.;
12) After completing the motor's idle test, reinstall the coupling intermediate section, concluding the installation with precision.
3.3.4 Post 'levelness' and alignment optimization, securely fasten the anchor bolts. During mechanical operations or trials, it's crucial to loosen and then retighten these bolts, reinforcing stability.
3.3.5 The impeller's rapid rotation mandates a pristine environment. Solid or liquid intrusion could inflict irreversible harm. Thus, it's vital to ensure the cleanliness of the inlet and outlet pipelines, adhering to the system's steam corrosion grade requirements. Any non-compliant pipelines must undergo immediate rectification.uggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Proceed with the installation of compressor inlet and outlet pipes. Follow the PI diagram for precise accessory placement. Ensure that the pipeline attached to the compressor is supported by an external bracket, so its weight does not bear upon the compressor body.
3.3.7 Once the main fan and its ancillary equipment have been meticulously installed and the concrete has reached full solidification, you are primed to initiate the compressor operation test. This marks the commencement of the testing phase, ensuring seamless functionality and performance of the system.
3.3.8 The electric control cabinet for the compressor must be strategically installed within a 5-meter radius of the compressor. Utilize threading pipes to connect the wiring from the compressor to the control cabinet, ensuring the wires are securely routed underground. Once the electric control cabinet is securely positioned, proceed to connect the wiring terminals within the cabinet to the lines at the remote Distributed Control System (DCS), establishing a robust and efficient communication link.
