MVR, an abbreviation for mechanical vapor recompression, stands as a pioneering energy-saving marvel. This technology dramatically minimizes the need for external energy sources by ingeniously harnessing and reusing the secondary steam it produces. At the heart of this process lies the fundamental principle where the secondary steam, generated within the evaporator, undergoes a transformation. Through a highly efficient steam compressor, this steam is compressed, converting electrical energy into invaluable thermal energy. This process elevates both the pressure and temperature of the secondary steam. The result? The elevated secondary steam is returned to the evaporator, allowing it to effectively heat materials and induce evaporation, achieving a remarkable recycling of the latent heat of vaporization. A masterful cycle of sustainability, innovation, and efficiency.
The DM series Single-stage geared steam compressor is a testament to precision engineering, encompassing a variety of integral components: the compressor body, coupling, gearbox, lubrication system, motor, electric instrumentation, and an advanced anti-surge control system. Designed with a compact structure, it offers unparalleled convenience for maintenance, ensuring seamless operation while minimizing downtime. Such a meticulous design not only optimizes functionality but also stands as a beacon of modern mechanical excellence.
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 Upon the installation of the main fan and its ancillary equipment, and once the concrete has reached its full strength and stability, the highly anticipated compressor operation test can commence. This crucial phase ensures the seamless performance and reliability of the Intelligent Steam Compressor with Enhanced Guide Vane Adjustment Features, crafted by NANTONG DART-RICH FAN CO., LTD.
3.3.8 Position the electric control cabinet of the compressor within a convenient 5-meter radius of the compressor itself to ensure optimal functionality. The meticulous connection from the compressor to this cabinet should be executed with precision using threading pipes, which are to be securely installed underground for safety and efficiency. Once the electric control cabinet is firmly in place, it's time to link the wiring terminals within the cabinet to the lines extending from the remote Distributed Control System (DCS), thereby establishing a robust and reliable connection for the Intelligent Steam Compressor's flawless operation.
