MVR, an acronym for Mechanical Vapor Recompression, is a groundbreaking energy-conserving technology designed to dramatically minimize the requirement for external energy sources. This innovative approach harnesses the power of secondary steam energy that it self-generates. At the heart of MVR's efficiency is its principle: the secondary steam, produced by the evaporator, undergoes compression using a high-efficiency steam compressor. This process masterfully converts electrical energy into thermal energy, subsequently elevating both the pressure and temperature of the secondary steam. The cleverly increased temperature of the secondary steam is then cycled back to the evaporator where it performs its dual magic—heating the materials and inducing evaporation. In this way, MVR ingeniously facilitates the recycling of the latent heat of vaporization from the secondary steam, optimizing energy usage and enhancing overall process efficiency.
The DML series, featuring a low temperature rise steam compressor, stands out with its meticulously engineered components. It comprises a robust compressor body equipped with a volute, impeller, main shaft, bearing housing, seal, and more, all working in harmony. The inclusion of a coupling, a powerful motor, and advanced electric instrumentation further accentuates its superior design. This well-thought-out assembly ensures optimal performance and reliability, offering an exceptional balance of efficiency and durability in handling demanding applications.
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 supporting equipment have been meticulously installed, and the concrete has reached full solidification, you are ready to initiate the operation test for the compressor. This crucial step ensures that the equipment functions seamlessly and demonstrates its readiness for full operational capacity.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within a proximity of 5 meters from the compressor itself. Ensure the connection from the compressor to this cabinet is executed with precision, using a threading pipe system that must be routed underground for optimal safety and efficiency. Upon securing the electric control cabinet in its designated place, seamlessly integrate the wiring terminals with the remote DCS lines, thus establishing a cohesive and reliable connection.
