MVR, an abbreviation for Mechanical Vapor Recompression, is a revolutionary energy-saving technology that significantly minimizes the need for external energy sources. This cutting-edge process cleverly reutilizes the secondary steam energy it generates, optimizing efficiency. At the heart of MVR lies its ingenious principle: the secondary steam produced by the evaporator undergoes a remarkable transformation. Utilizing a high-efficiency steam compressor, the system adeptly converts electrical energy into potent thermal energy. As a result, the pressure and temperature of the secondary steam ascend, enabling its return to the evaporator. This seamless cycle allows the steam to heat materials and initiate evaporation, ingeniously recycling the latent heat of vaporization inherent in the secondary steam. This process not only represents a breakthrough in energy conservation but also underscores our commitment to innovative wastewater management solutions.
The DM series Single-stage Geared Steam Compressor is an engineering marvel that embodies precision and efficiency. It predominantly consists of several integral components: the robust compressor body, durable coupling, sophisticated gearbox, efficient lubrication system, reliable motor, advanced electric instrumentation, and a state-of-the-art anti-surge control system. Boasting a compact architecture, it is designed for ease of maintenance, ensuring longevity and peak performance. This meticulously crafted system is a testament to modern engineering, offering unparalleled convenience and reliability in its operation.
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 primary fan and its associated apparatus have been meticulously installed and the concrete has reached full strength, it's time to embark on the compressor operation test. This crucial step promises to validate the performance and functionality, ensuring seamless operation of your cutting-edge system.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within a 5-meter radius of the compressor itself. To ensure a streamlined and organized setup, the wiring from the compressor to the control cabinet is recommended to be securely connected through underground threading pipes. Upon the cabinet's placement, expertly connect the wiring terminals within the cabinet to the lines at the remote DCS, ensuring a flawless integration and optimal performance.
