MVR, which stands for Mechanical Vapor Recompression, is a groundbreaking energy-efficient innovation that dramatically reduces the need for external energy consumption. This cutting-edge technology works by ingeniously reutilizing the energy of secondary steam that it generates. The core principle involves compressing the secondary steam produced by the evaporator using a high-efficiency steam compressor. This process ingeniously converts electrical energy into thermal energy, elevating the pressure and temperature of the secondary steam. As a result, the elevated temperature reintroduces the secondary steam back to the evaporator to heat the materials, instigating evaporation. This seamless cycle effectively recycles the latent heat of vaporization of the secondary steam, ensuring optimal energy conservation.
The DM series Single-stage Geared Steam Compressor is meticulously crafted to deliver unmatched performance and reliability. Key components of this premium compressor include the robust compressor body, durable coupling, precision-engineered gearbox, efficient lubrication system, powerful motor, advanced electronic instrumentation, and a state-of-the-art anti-surge control system. Its design boasts a compact structure, offering unparalleled convenience for maintenance. This makes it an ideal choice for those seeking both efficiency and ease of use.
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 ancillary components are expertly installed and the concrete foundation has reached full solidity, the pathway to conducting a seamless compressor operation test is open. This essential step ensures the high performance and efficiency of the system, setting the stage for optimal operation.
3.3.8 The electric control cabinet for the compressor, a crucial component, should be strategically positioned no more than 5 meters from the compressor itself. The connection between the compressor and the cabinet should be meticulously routed through an underground threading pipe. Once the electric control cabinet is firmly in place, establish a secure connection between the wiring terminals within the cabinet and the remote DCS lines, ensuring a smooth and reliable communication flow.
