MVR, which stands for mechanical vapor recompression, is a cutting-edge energy-saving technology designed to dramatically reduce the demand for external energy. This is achieved by ingeniously reutilizing the secondary steam energy it generates. At its core, this technology operates on a brilliant principle: the secondary steam produced by the evaporator is efficiently compressed using a high-energy-efficiency steam compressor. This process adeptly transforms electrical energy into thermal energy, resulting in an increase in both pressure and temperature of the secondary steam. The elevated temperature of this secondary steam allows it to return to the evaporator, where it plays a crucial role in heating materials and driving evaporation. This cycle effectively enables the recycling of latent heat from the vaporization of the secondary steam, making it a remarkably sustainable and efficient solution.
The DM series Single-stage geard steam compressor is a masterpiece of engineering, comprising a meticulously designed compressor body, a robust coupling, a high-performance gearbox, a state-of-the-art lubrication system, a powerful motor, and a sophisticated electric instrument and anti-surge control system. Its design boasts a remarkably compact structure, ensuring ease of maintenance while delivering exceptional performance. This advanced piece of technology is crafted to meet the highest standards of functionality and reliability, making it an ideal choice for those seeking superior quality and efficient operation.
3.3.1 Begin by seamlessly placing the compressor base on the foundation. To achieve perfect leveling of the unit, insert wedge-shaped shims strategically underneath the base. Alternate the placement of two wedge-shaped irons, and once the unit is precisely leveled, secure the stability by spot welding these irons at 4-5 points. Note that the fabrication and installation of wedges should align with the specific conditions of your setup. Ensure that the contact surfaces are finely finished for optimal contact and that the wedge iron's load capacity does not exceed 40 Kg/cm.
place two wedge-shaped irons alternately, after leveling the unit, and spot weld the wedge-shaped irons for 4~5 points. The wedge shall be
manufactured and installed by the user according to the actual situation, and the contact surface shall be finished (even contact of inclined
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Utilize a level to meticulously ascertain the horizontal alignment. Adhere to the unit's leveling specifications: achieve an axial level precision of 0.05/1000mm and ensure the horizontal level does not deviate beyond 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Centering the coupling is crucial. Before embarking on alignment, please verify the following prerequisites:
1) Ensure the primary power supply is completely switched off;
2) Dismantle the coupling shield to access the necessary components;
3) Detach the diaphragm coupling's intermediate section;
4) Inspect the motor installation plane's flatness, confirming the absence of any foreign particles, grime, or unwanted materials;
5) The motor bolt holes should be adequately larger than the bolts themselves to facilitate loosened adjustments to fine-tune the motor position;
6) Have a sufficient supply of stainless steel gaskets ready to cover the motor's feet. Ensure these gaskets are devoid of any debris, are flat, and avoid using extended, slender gaskets for adjustments between the motor and base;
7) Equip yourself with a dial indicator or a laser alignment meter boasting a remarkable accuracy of 0.01mm (to be provided by the customer);
8) Prepare the necessary bracket as illustrated below to support the dial indicator effectively;
9) Employ the motor wheel hub mounting bracket to secure a dial indicator on the wheel hub's edge, placing the dial indicator probe against the compressor wheel hub's outer edge;
10) Adjust around the motor feet to align the compressor and motor center lines. The maximum allowable outer circle deviation is 0.05mm (ensuring the motor shaft center is slightly higher than the compressor's low-speed shaft center), and the coupling end face should be within 0.03~0.05mm;
11) Conclude by securely tightening the motor foot bolts, reassessing the coupling for any outer circle runout and end face runout;;
12) Upon a successful motor idling test, reinstall the coupling intermediate section.
3.3.4 Post alignment adjustment, secure the casing's levelness, and firmly tighten the anchor bolts. After a mechanical or trial run, retighten them to ensure stability.
3.3.5 The impeller, a high-speed rotational element, is sensitive to intrusions of solids or liquids, which can inflict irreversible damage to the compressor. Thus, it is imperative to maintain cleanliness in the pipelines interfacing with the compressor, meeting the steam corrosion standards of the system. Rectify any pipelines failing to meet these criteria. It is advisable to integrate solid-liquid separation apparatus, such as a gas scrubber or sedimentation tee, prior to the straight pipe at the compressor's inlet.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. Ensure compliance with the PI diagram for all relevant pipeline accessories. The pipeline affixed to the compressor must be supported independently by an additional bracket, ensuring that its weight is not borne by the compressor itself.
3.3.7 Once the main fan and its accompanying ancillary equipment are securely installed and the concrete has reached full solidity, you are ready to embark on the compressor operation test. This crucial step ensures that everything functions flawlessly, setting the stage for optimal performance.
3.3.8 For seamless integration, the electric control cabinet of the compressor must be strategically positioned within a 5-meter radius of the compressor. It is essential to use threading pipe to connect the wiring from the compressor to the control cabinet, ensuring that it is routed underground for safety and efficiency. Upon positioning the electric control cabinet, meticulously connect the wiring terminals inside with the lines at the remote DCS, completing the sophisticated network for superior operational control.
