MVR, known as mechanical vapor recompression, is an innovative energy-efficient technology that significantly reduces the need for external power by harnessing and re-utilizing the energy from secondary steam it produces. The core principle involves compressing the secondary steam generated by the evaporator using a high-efficiency steam compressor. This process converts electrical energy into thermal energy, increasing the pressure and temperature of the secondary steam. The elevated temperature and pressure allow the secondary steam to be redirected back to the evaporator, where it heats the materials, thereby generating further evaporation. This remarkable method enables the recycling of the latent heat of vaporization of secondary steam, ensuring a sustainable and energy-efficient process.
The DM series Single-stage geared steam compressor is an exceptional machinery marvel that encompasses a compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. Its design is characterized by a compact structure, ensuring it is both easy to maintain and efficient in operation. The thoughtful engineering behind this series ensures reliability and performance, making it a top choice for those seeking superior technology.
3.3.1 Begin by positioning the compressor base seamlessly on the prepared foundation. Introduce wedge-shaped shims beneath this base to adeptly adjust the unit's level.
Place these precise wedge-shaped irons in an alternating sequence. Once the unit achieves perfect leveling, strategically spot weld the wedge-shaped irons at 4 to 5 key points.
These wedges are to be crafted and fitted by the user, tailored to the installation's unique circumstances. Ensure that the contact surfaces are meticulously finished for uniform contact.
The inclined plane must exhibit even contact, and the load-bearing capability of these wedge irons should not surpass 40Kg/cm2).
3.3.2 Employ a precision level to ascertain the unit's level. The exacting requirements demand an axial level of 0.05/1000mm, and a horizontal level precision of 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Achieve coupling alignment. Prior to commencing alignment, ensure these essential prerequisites are met:
1) Securely disconnect the main power supply;
2) Dismantle the coupling shield with care;
3) Extract the diaphragm coupling's intermediate section;
4) Verify the motor installation plane's flatness, ensuring it's free from any obstructions, dirt, or extraneous materials;
5) Ensure the motor bolt hole exceeds the bolt size to facilitate loosening for motor adjustments;
6) Amass ample stainless steel gaskets to securely support the motor's foot. These gaskets must be devoid of attachments and perfectly flat; avoid inserting long or thin gaskets.
7) Utilize a dial indicator or a laser alignment meter boasting an accuracy of 0.01mm (procured by the customer);
8) Have the necessary bracket ready to support the dial indicator, as illustrated in the accompanying diagram;
9) Use the motor wheel hub mounting bracket to position a dial indicator on the hub's edge, situating the probe on the compressor wheel hub's outer edge;
10) By fine-tuning the adjustment bolts surrounding the motor feet, align the compressor and motor center lines accurately (or follow the corresponding guidelines) with a maximum outer circle deviation of 0.05mm. The motor shaft center should be elevated compared to the compressor's low-speed shaft center line, with the coupling end face maintaining a precision of 0.03~0.05mm;
11) Conclusively, secure the motor foot bolts, then verify both the outer circle runout and end face runout of the coupling;
12) Reattach the coupling intermediate section following a successful motor idling test.
3.3.4 Post-adjustment of the casing's 'levelness' and alignment, ensure the anchor bolts are tightly fastened. After the mechanical operation (or trial execution), loosen and retighten the bolts to guarantee security.
3.3.5 The impeller, as a high-velocity rotating element, is susceptible to irreversible damage from any solid or liquid ingress. Therefore, it is imperative to maintain cleanliness in the inlet and outlet pipelines connected to the compressor, aligning with the system's steam corrosion grade standards. Pipelines falling short of these standards necessitate rectification. It is advised to incorporate solid-liquid separation equipment (such as a gas scrubber or sedimentation tee) prior to the straight pipe at the compressor inlet to ensure optimal protection.uggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Proceed to install the compressor's inlet and outlet pipes. These crucial import and export pipelines should be equipped with the necessary pipeline accessories as outlined in the PI diagram. Importantly, the pipeline connected to the compressor should be supported by a separate bracket to prevent burdening the compressor body with its weight, ensuring stability and longevity.
3.3.7 Once the main fan along with its supporting equipment has been meticulously installed and the concrete foundation has reached its full strength, we are ready to proceed with the exciting compressor operation test.
3.3.8 To ensure optimal functionality, the electric control cabinet for the compressor should be strategically positioned within a 5-meter radius of the compressor itself. The connection between the compressor and the electric control cabinet should be expertly routed through a threading pipe, discreetly positioned underground. Once the electric control cabinet is perfectly situated, make sure to seamlessly connect the wiring terminals within it to the lines at the remote DCS, ensuring flawless performance.
