MVR, which stands for mechanical vapor recompression, is a groundbreaking energy-saving technology designed to significantly reduce the need for external energy by expertly reutilizing the energy of secondary steam it produces. The fundamental principle at work here is the compression of secondary steam generated by the evaporator using a high-efficiency steam compressor. This process masterfully transforms electrical energy into thermal energy, leading to an increase in both pressure and temperature of the secondary steam. The elevated temperature steam is then channeled back to the evaporator, where it heats the materials and induces evaporation. This innovative cycle ensures the efficient recycling of the latent heat of vaporization of secondary steam, showcasing a remarkable achievement in energy efficiency and sustainability.
The DM series Single-stage geared steam compressor is a marvel of engineering, comprising critical components such as the compressor body, coupling, gearbox, lubrication system, motor, and sophisticated electric instruments. Additionally, it is equipped with an advanced anti-surge control system. This compressor is renowned for its compact and robust structure, making it exceptionally convenient for maintenance. Its design embodies a perfect blend of reliability and cutting-edge technology, ensuring seamless operation and longevity.
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 supplementary equipment have been securely installed and the concrete has reached full solidity, you're ready to perform the compressor operation test. This ensures the Reliable Watervapour Compressor with Overall Base for Vanadium Extraction is primed for optimal performance, meeting the high standards set by NANTONG DART-RICH FAN CO.,LTD.
3.3.8 For seamless operation, the electric control cabinet of the compressor must be situated within a 5-meter radius of the compressor itself. To ensure a clean and efficient setup, connect the wiring from the compressor to the control cabinet using threading pipe, which should be routed underground. Once the control cabinet is positioned, it is crucial to link the wiring terminals within the cabinet to the lines at the remote DCS. This meticulous setup guarantees a streamlined and efficient operation, embodying the reliability and precision synonymous with NANTONG DART-RICH FAN CO.,LTD's cutting-edge technology.
