MVR, or mechanical vapor recompression, represents a groundbreaking energy-efficient technology designed to dramatically decrease external energy consumption. By innovatively harnessing the power of secondary steam energy, it sets a new standard for sustainable operations. The core principle involves the use of a highly efficient steam compressor to compress secondary steam generated by the evaporator. This process transforms electrical energy into thermal energy, elevating both the pressure and temperature of the secondary steam. The elevated steam is then cycled back to the evaporator, effectively heating the materials and triggering evaporation. This ingenious method ensures the recycling of the latent heat of vaporization within the secondary steam, redefining energy sustainability.
The DML series low temperature rise steam compressor stands out with its advanced engineering and design, featuring a robust compressor body that includes components such as the volute, impeller, main shaft, bearing housing, and seal. This sophisticated system is further enhanced by a coupling, motor, and electric instruments, all seamlessly integrated to deliver unparalleled efficiency and performance. Each element is precision-crafted to ensure reliable operation and optimal energy conversion, making the DML series an essential asset for industries aiming to maximize energy savings while maintaining high levels of operational 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 Once the main fan and its support equipment are meticulously installed, and the concrete foundation has fully solidified to ensure maximum stability, you can proceed confidently with the operational testing of the compressor. This vital step ensures that the Low Temperature Rise Steam Compressor performs optimally under real-world conditions.
3.3.8 For optimum performance and safety, the electric control cabinet of the compressor should be strategically installed within a 5-meter radius of the compressor unit. It is essential that the wiring from the compressor to this control cabinet is precisely connected using a threading pipe, securely routed underground to avoid any disruptions. Once the electric control cabinet is installed, seamlessly connect the wiring terminals within it to the lines at the remote DCS, ensuring a smooth and efficient operation.
