MVR, an abbreviation for Mechanical Vapor Recompression, represents a cutting-edge, energy-efficient technology designed to dramatically minimize the need for external energy resources. This is achieved by ingeniously repurposing the secondary steam energy generated during operation. The core principle revolves around compressing the secondary steam produced by the evaporator using a high energy efficiency steam compressor. This process skillfully transforms electrical energy into thermal energy, thereby elevating the pressure and temperature of the secondary steam. The augmented temperature and pressure conditions enable the secondary steam to be redirected to the evaporator, effectively heating the materials and initiating further evaporation. As a result, the latent heat of vaporization of the secondary steam is ingeniously recycled, showcasing a brilliant innovation in sustainable energy use.
The DM series Single-stage Geared Steam Compressor stands out with its sophisticated design, featuring a compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. Its compact, streamlined structure is not only a testament to engineering excellence but also ensures ease of maintenance and operational convenience. This meticulously crafted compressor is engineered to deliver unparalleled performance while maintaining a user-friendly maintenance profile.
3.3.1 Begin by positioning the compressor base integrally onto its foundation. Use wedge-shaped shims beneath the base for precision leveling.
Place these wedges in an alternating fashion. Once achieving perfect leveling, secure the wedges with spot welds at 4 to 5 strategic points.
Users must manufacture and fit the wedges tailored to their specific installation environment, ensuring a flawless contact surface.
The inclined plane must make complete contact, and the wedge iron’s load capacity must not surpass 40Kg/cm2).
3.3.2 Utilize a precise level to ensure perfection. The unit's axial level precision demands a tolerance of 0.05/1000mm, while its horizontal alignment requires 0.10/1000mm.
3.3.3 Achieve coupling precision by centering it meticulously. Prior to alignment, ensure these essentials are met:
1) Disconnect the main power supply to prevent any hazards;
2) Dismantle the coupling shield for clear access;
3) Carefully remove the diaphragm coupling intermediate section;
4) Meticulously inspect the motor installation plane's flatness, ensuring it is free from any unwanted debris or obstructions;
5) The motor’s bolt holes must exceed the bolt size, allowing for necessary adjustments by loosening;
6) Equip with a sufficient array of stainless steel gaskets to firmly support the motor feet. Ensure these gaskets are spotless and perfectly flat.
7) Precision is key. Use a dial indicator or a laser alignment meter, ensuring an accuracy of 0.01mm. Customers must provide these tools;
8) Have a bracket ready to support the dial indicator, as depicted in the reference figure below;
9) The motor wheel hub’s custom bracket is designed for positioning a dial indicator at the wheel hub's edge, ensuring precise measurements on the compressor's wheel hub.
10) By fine-tuning the adjustment bolts surrounding the motor feet, align the compressor and motor center lines to perfection.
11) Securely fasten the motor foot bolts and re-evaluate any runouts in the coupling’s outer circle and end face.;
12) After conducting a motor idling test, proceed to install the coupling intermediate section.
3.3.4 With the 'levelness' and alignment perfected, tighten the anchor bolts securely. Following a mechanical operation or trial, release and retighten the bolts for ensured stability.
3.3.5 The impeller, a high-speed marvel, demands protection from any solid or liquid encounters. Such impurities can inflict irreversible harm.Ensure all connected pipelines are pristine and adhere to the steam corrosion standards of the system. Non-compliant pipelines require immediate rectification. Incorporating solid-liquid separation units, like gas scrubbers or sedimentation tees, is highly recommended before the compressor inlet's straight pipe.
3.3.6 Proceed to expertly install the compressor’s inlet and outlet pipes. Ensure all pipelines are fitted with appropriate accessories as per the PI diagram. The compressor body must not bear the pipeline's weight; provide alternative support through another robust bracket.
3.3.7 Once the majestic main fan and its supportive ancillary equipment have been meticulously installed, and the robust concrete has reached full solidity, it is time to proceed with the exhilarating compressor operation test.
3.3.8 Position the electric control cabinet of the compressor within a convenient 5 meters of the compressor itself. Ensure that the wiring from the compressor to the electric control cabinet is impeccably connected using a threading pipe that runs strategically underground. Once the electric control cabinet is securely stationed, seamlessly connect its wiring terminals to the remote DCS lines.
