MVR, an abbreviation for Mechanical Vapor Recompression, represents a cutting-edge energy conservation technology designed to significantly decrease the reliance on external energy sources. This is achieved through the innovative reuse of secondary steam energy it produces. The core principle behind MVR lies in the compression of secondary steam that is generated by the evaporator. Using a highly efficient steam compressor, this process converts electrical energy into thermal energy. Subsequently, the pressure and temperature of the secondary steam are elevated. This temperature increase allows the secondary steam to be redirected back to the evaporator, where it effectively heats the materials, promoting evaporation. Through this ingenious cycle, the latent heat of vaporization of the secondary steam is continuously recycled, demonstrating a remarkable synergy between energy efficiency and sustainable practices.
The DM series Single-stage Geared Steam Compressor is a masterpiece of engineering that integrates several critical components to ensure optimal performance. It features a robust compressor body, precision coupling, an advanced gearbox, and a sophisticated lubrication system. Complementing these mechanical elements is a powerful motor, a comprehensive electric instrument panel, and a state-of-the-art anti-surge control system. Designed with a focus on compactness, this compressor not only offers ease of maintenance but also provides unparalleled reliability and efficiency, making it an indispensable asset in cutting-edge engineering solutions.
3.3.1 The compressor base is integrally placed on the foundation, put wedge-shaped shim under the base (used to adjust the unit level),
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 Use a level to find the level. The leveling requirements of the unit: the axial level of the unit is 0.05/1000mm, and the horizontal
level of the unit is 0.10/1000mm.
3.3.3 Coupling is centered. Before starting alignment, confirm the following requirements:
1) Turn off the main power supply;
2) Remove the coupling shield;
3) Remove the diaphragm coupling intermediate section;
4) Check the flatness of the motor installation plane to ensure that there are no stolen goods, dirt and attachments;
5) The motor bolt hole should be larger than the bolt size, so that the bolt can be loosened to adjust the motor;
6) Prepare enough stainless steel gaskets to cover the foot of the motor, the gaskets should not have attachments and should be flat enough. You cannot use long and thin gaskets to insert between the motor and the base for adjustment;
7) Use a dial indicator or a laser alignment meter with an accuracy of 0.01mm (prepared by the customer himself);
8) Prepare the bracket for supporting the dial indicator as shown in the figure below;
9) The motor wheel hub mounting bracket is used for mounting a dial indicator on the edge of the wheel hub, and placing a dial indicator probe on the outer edge of the compressor wheel hub;
10) By adjusting the adjustment bolts around the motor feet, the compressor and the motor center line are basically on the same line (or according to the corresponding instructions), and the maximum deviation of the outer circle is 0.05mm (the motor shaft center line should be higher than the compressor low-speed shaft center line), coupling end face 0.03~0.05mm;
11) Finally, tighten the motor foot bolts, and review the outer circle runout and end face runout of the coupling;
12) Install the coupling intermediate section after the motor idling test.
3.3.4 After adjusting the "levelness" and alignment of the casing, tighten the anchor bolts. After the mechanical operation (or trial operation), loosen the bolts and tighten them again.
3.3.5 The impeller is a high speed rotating component, and any solid or liquid entering impeller will cause irreversible damage to compressor. Therefore, it is necessary to ensure that the inlet and outlet pipelines connected with compressor are clean and meet the requirements of steam corrosion grade of the system. Pipelines that do not meet this condition must be rectified. It is suggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Install compressor inlet and outlet pipes. Import and export pipelines shall be installed with relevant pipeline accessories according to PI diagram. The pipeline connected to the compressor shall be supported by another bracket, and its weight shall not be supported by the compressor body.
3.3.7 In the innovative journey of installing the main fan and its essential ancillary equipment, one must wait patiently for the concrete to reach perfect solidification. Upon reaching this pivotal stage, you are poised to initiate the exhilarating compressor operation test, a decisive step in ensuring optimal performance for our Split Base Compressor with Advanced Speed Regulation.
3.3.8 For seamless integration of our Split Base Compressor, the electric control cabinet must be strategically installed within a 5-meter radius of the compressor. The connection, facilitated by threading pipes, journeys underground, ensuring a sleek and secure path from the compressor to the control hub. Once the electric control cabinet is firmly in place, it is vital to meticulously connect the wiring terminals with the remote DCS lines, creating a harmonious operational flow.
