MVR, which stands for mechanical vapor recompression, epitomizes a state-of-the-art energy conservation technology. It ingeniously diminishes the necessity for external power by masterfully harnessing and reusing the secondary steam energy it produces. The core principle is brilliantly simple yet highly efficient: the secondary steam, birthed from the evaporator, is expertly compressed using a high-energy efficiency steam compressor. This transformative process converts electrical power into thermal energy, culminating in an impressive rise in both the pressure and temperature of the secondary steam. Subsequently, this heightened temperature allows the steam to return triumphantly to the evaporator, efficiently heating the materials and sparking evaporation. This results in a magnificent recycling of the latent heat of vaporization, ushering in a new era of energy utilization.
The DML series low temperature rise steam compressor stands as an exemplar of advanced engineering. It comprises an intricately designed compressor body, which includes essential components such as the volute, impeller, main shaft, bearing housing, and seal. Complemented by a coupling, powerful motor, and cutting-edge electric instruments, this innovative apparatus promises durability and unparalleled performance. Each component is crafted with precision to ensure seamless operation, making it an essential asset for any energy-efficient process.
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, along with all its ancillary equipment, has been thoroughly installed and the concrete foundation has completely solidified, you are ready to conduct the operational test of the compressor. This marks a crucial step in ensuring the seamless performance of our cutting-edge Low Temperature Rise Steam Compressor, proudly crafted by NANTONG DART-RICH FAN CO.,LTD. With its innovative durable overall base design, this test is essential to verify the reliability and efficiency of the installation.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within a 5-meter radius of the compressor itself. For optimal functionality and streamlined integration, the wiring from the compressor to the cabinet must be channeled through a threading pipe situated underground. Once the electric control cabinet is securely installed, make sure to connect the wiring terminals within the cabinet to the lines at the remote DCS. This meticulous setup ensures that our Low Temperature Rise Steam Compressor operates with precision and control, maintaining the high standards of excellence set by NANTONG DART-RICH FAN CO.,LTD.
