MVR, an abbreviation for Mechanical Vapor Recompression, represents a groundbreaking, energy-efficient technology designed to drastically cut down on external energy consumption. This is achieved through the ingenious reutilization of secondary steam energy that it produces. The core principle behind MVR involves compressing secondary steam generated by an evaporator using a high-efficiency steam compressor. This process transforms electrical energy into thermal energy, resulting in an increase in both pressure and temperature of the secondary steam. The elevated temperature and pressure facilitate the return of the secondary steam to the evaporator, where it efficiently heats materials, sparking a cycle of evaporation. This seamless process not only enhances the recycling of latent heat from vaporization of secondary steam but also promotes a sustainable and environmentally-friendly energy cycle.
The DM series Single-stage Geared Steam Compressor is a remarkable piece of engineering, encompassing a comprehensive range of components including the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. What sets this compressor apart is its compact and robust structure, which not only ensures reliability but also simplifies maintenance, making it an ideal choice for those seeking long-term efficiency and convenience in steam compression solutions.
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 successful installation of the main fan and its supporting apparatus, and after ensuring that the concrete has reached full solidification, you are ready to commence the compressor operation test with confidence.
3.3.8 The electric control cabinet for the compressor should be strategically installed within a proximity of 5 meters from the compressor itself. The wirings connecting the compressor to this control cabinet must be neatly organized through threading pipe, which should be routed underground for safety and aesthetics. Once the electric control cabinet is securely positioned, proceed to connect the wiring terminals inside with the lines at the remote DCS, ensuring seamless integration and operation.
