MVR, or Mechanical Vapor Recompression, is an advanced energy-saving technology designed to significantly cut down on external energy needs by intelligently repurposing the secondary steam energy it creates. The core principle behind MVR is the transformation of secondary steam generated by the evaporator. This is achieved through a high-efficiency steam compressor that skillfully converts electrical energy into thermal energy. As a result, there is an increase in both the pressure and temperature of the secondary steam. This elevated temperature then allows the secondary steam to return to the evaporator, where it efficiently heats the materials, triggering further evaporation. This ingenious process ensures the continuous recycling of the latent heat of vaporization for the secondary steam, optimizing energy utilization at every stage.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, comprising several key components such as the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. It boasts a compact structure that is not only space-efficient but also facilitates easy maintenance. This thoughtfully designed system ensures high performance, reliability, and longevity, making it an ideal choice for modern industrial applications.
3.3.1 Begin by placing the compressor base integrally upon its designated foundation. Position wedge-shaped shims beneath the base to achieve optimal leveling of the unit. These carefully crafted shims facilitate precise adjustments to ensure the unit remains perfectly level.
Lay the wedge-shaped irons alternately, ensuring they snugly fit. Once the unit is leveled with precision, proceed to spot weld the wedge-shaped irons at 4 to 5 points, securing them firmly in place. These wedges are to be
custom-made and installed by the user, tailored to the specific conditions of the installation. The contact surfaces must be finished to perfection, ensuring even and seamless contact on the inclined plane, and
ensuring the bearing capacity of each wedge iron does not exceed 40Kg/cm2).
3.3.2 Employ a precise level to ascertain the levelness of the unit. The leveling criteria are exacting: the axial level tolerance is set at 0.05/1000mm, while the horizontal
level tolerance is maintained at 0.10/1000mm to ensure peak operational efficiency.
3.3.3 Establish coupling alignment meticulously. Prior to commencing alignment, ensure the following conditions are met:
1) Disconnect the main power supply to prevent any electrical hazards;
2) Detach the coupling shield for unobstructed access;
3) Remove the diaphragm coupling intermediate section for clear alignment;
4) Verify the motor installation plane is impeccably flat and free from any impurities or attachments;
5) Confirm that the motor bolt holes are ample, allowing bolts to be loosened for fine motor adjustments;
6) Prepare an adequate number of stainless steel gaskets to fully support the motor foot. These gaskets must be devoid of any contaminants and offer sufficient flatness, avoiding the use of elongated or thin gaskets during adjustments;
7) Utilize a dial indicator or a laser alignment meter with an accuracy of 0.01mm, provided by the customer, to achieve precise alignment;
8) Prepare a bracket as illustrated in the diagram to support the dial indicator effectively;
9) Employ a motor wheel hub mounting bracket to facilitate the mounting of a dial indicator on the hub's edge, placing the indicator probe on the compressor wheel hub's outer edge;
10) Through meticulous adjustment of the bolts around the motor feet, align the compressor and motor center lines with utmost precision (or follow specific instructions). The maximum permissible deviation of the outer circle is 0.05mm, with the motor shaft center line positioned slightly higher than the compressor low-speed shaft center line, and coupling end face tolerances between 0.03~0.05mm;
11) Securely tighten the motor foot bolts, and conduct a thorough review of the outer circle runout and end face runout of the coupling;
12) Reinstall the coupling intermediate section following a successful motor idle test.
3.3.4 Upon achieving the desired "levelness" and alignment of the casing, fasten the anchor bolts securely. Post mechanical operation or trial run, loosen and then retighten the bolts to ensure continued stability.
3.3.5 The impeller, a high-speed rotating component, demands stringent precaution to prevent any solid or liquid intrusion, which could induce irreversible damage to the compressor. It is imperative to maintain cleanliness of the inlet and outlet pipelines connected to the compressor, conforming to the system's required steam corrosion grade. Rectification is mandatory for pipelines that fail to meet these standards. It is highlyrecommended to incorporate solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, preceding the compressor inlet's straight pipe to safeguard the integrity of the system.
3.3.6 Proceed to install the compressor inlet and outlet pipes. Ensure that the import and export pipelines are equipped with the necessary pipeline accessories as per the PI diagram. It is crucial to support pipelines connected to the compressor with an independent bracket, ensuring that their weight is not imposed upon the compressor body.
3.3.7 Following the successful installation of the main fan and its accompanying equipment, and once the concrete has reached full solidity, you are ready to embark on the pivotal compressor operation test. This crucial step ensures everything is in optimal working order before full-scale operations commence.
3.3.8 For optimal performance and streamlined operations, the electric control cabinet of the compressor needs to be strategically positioned within a 5-meter radius of the compressor. The wiring should be meticulously connected using threading pipes that are securely routed underground. Once the control cabinet is installed, make sure to carefully connect the wiring terminals inside the cabinet with the designated lines at the remote DCS, ensuring seamless integration and operational efficiency.
