MVR, standing for Mechanical Vapor Recompression, represents a cutting-edge energy-saving technology meticulously designed to dramatically curb the need for external energy sources. This is marvelously achieved by the ingenious reutilization of secondary steam energy, which is self-generated. At the core of this revolutionary process is a fundamental principle: secondary steam, emerging from the evaporator, is skillfully compressed using a highly efficient steam compressor. This transforms electrical energy seamlessly into thermal energy. As a result, the secondary steam undergoes a remarkable rise in both pressure and temperature. The magic continues as this heated secondary steam returns to the evaporator, where it tirelessly heats materials and spurs vibrant evaporation. This cycle brilliantly recycles the latent heat of vaporization of secondary steam, epitomizing sustainability and efficiency.
The DM series Single-Stage Geared Steam Compressor is a marvel of engineering, boasting a meticulously designed structure that includes several key components: the robust compressor body, precision coupling, and an intricate gearbox. Additionally, it features a state-of-the-art lubrication system and a powerful motor, complemented by a sophisticated electric instrument suite. The anti-surge control system further enhances its reliability. With its compact structure, this compressor offers unparalleled convenience in maintenance, promising longevity and consistent performance.
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 Once the main fan and its accompanying equipment have been masterfully installed and the concrete has reached its full solidified strength, it is time to embark on the operational journey of the compressor by conducting a comprehensive and thorough operation test. This pivotal moment ensures that every component works harmoniously for optimal performance.
3.3.8 For seamless integration and optimal performance, the electric control cabinet of the compressor should be strategically positioned within a 5-meter radius of the compressor. The connection between the compressor and the electric control cabinet should be achieved using a threading pipe, carefully placed underground to ensure durability and protection. Upon positioning the electric control cabinet, skillfully connect the wiring terminals within the cabinet to the circuits at the remote DCS, ensuring a flawless and uninterrupted flow of power and control.
