MVR, or Mechanical Vapor Recompression, is a cutting-edge energy-conserving technology designed to drastically cut down on external energy usage. This innovative system ingeniously reutilizes the secondary steam energy it generates. The core principle behind this system is to take the secondary steam produced by the evaporator and compress it using a highly efficient steam compressor. This process transforms electrical energy into thermal energy, elevating the pressure and temperature of the secondary steam. The increased temperature of the secondary steam is then cycled back to the evaporator to heat the materials, promoting further evaporation. This cycle ensures the continuous recycling of the latent heat of vaporization contained within the secondary steam, making it a marvel of modern energy efficiency.
The DM Series Single-stage Geared Steam Compressor is meticulously engineered with a robust yet compact design. This sophisticated piece of machinery comprises several essential components: a durable compressor body, precise coupling, efficient gearbox, reliable lubrication system, powerful motor, sophisticated electric instruments, and an advanced anti-surge control system. Its compact structure not only optimizes space but also simplifies maintenance, ensuring that the system operates seamlessly with minimal downtime.
3.3.1 The compressor base is integrally placed on the foundation, and it is crucial to position wedge-shaped shims beneath the base to adjust the unit level. This foundational setup ensures optimal performance.
Alternate two wedge-shaped irons and, upon achieving perfect leveling of the unit, spot weld the irons at 4~5 strategic points. These wedges should be
manufactured and installed by the user in accordance with actual conditions, ensuring that the contact surface is meticulously finished for even contact on the inclined
plane. Additionally, the bearing capacity of these wedge irons must not exceed 40Kg/cm2.).
3.3.2 Utilize a precise level to ascertain perfect alignment. The unit's leveling requirements are stringent: the axial level must be 0.05/1000mm, while the horizontal
level should maintain an accuracy of 0.10/1000mm.
3.3.3 Proper coupling alignment is critical. Before commencing alignment, please ensure the following pre-requisites are met:
1) Disengage the main power supply;
2) Remove the protective shield from the coupling;
3) Detach the intermediate section of the diaphragm coupling;
4) Verify the motor installation plane's flatness to ensure it is free of debris, dirt, and other attachments;
5) The motor bolt hole should exceed the bolt's size, allowing the bolts to be loosened for motor adjustments;
6) Equip yourself with ample stainless steel gaskets to accommodate the motor's foot. Ensure these gaskets are free of attachments and are perfectly flat. Avoid using long, thin gaskets between the motor and the base for adjustments.
7) Employ a dial indicator or a laser alignment meter with an accuracy of 0.01mm, which should be procured by the customer;
8) Prepare a suitable bracket to support the dial indicator as illustrated in the accompanying diagram;
9) Utilize a motor wheel hub mounting bracket for mounting a dial indicator onto the hub's edge, ensuring the probe touches the outer edge of the compressor wheel hub.
10) Adjust the bolts around the motor feet to align the compressor and motor center lines precisely. The maximum deviation allowed for the outer circle is 0.05mm, with the motor shaft center line positioned slightly above the compressor's low-speed shaft center line. Maintain a coupling end face deviation of 0.03~0.05mm;
11) Conclude by firmly tightening the motor foot bolts and re-evaluating the coupling’s outer circle and end face runout for precision.;
12) Re-install the intermediate section of the coupling post motor idling test.
3.3.4 After meticulously adjusting the casing’s "levelness" and alignment, tighten the anchor bolts. Post mechanical or trial operation, loosen the bolts and retighten them to affirm stability.
3.3.5 The impeller, a high-speed rotating component, demands special attention as any foreign solid or liquid intrusion could irrevocably damage the compressor. To avert such risks, ensure that all pipelines interfacing with the compressor are impeccably clean and conform to the system's steam corrosion grade requirements. Any pipelines failing to meet these standards must be rectified.Consider installing solid-liquid separation equipment (such as a gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet for additional protection.
3.3.6 Proceed to install the compressor's inlet and outlet pipes. Install associated pipeline accessories as per the PI diagram specifications. Note that the pipeline attached to the compressor should be supported by an external bracket, ensuring that its weight does not burden the compressor body.
3.3.7 Once the main fan, along with all of its ancillary equipment, is securely installed and the concrete foundation has fully solidified, you can proceed with conducting the compressor operation test. This crucial step ensures optimal functionality and reliability, providing peace of mind for seamless operations.
3.3.8 The electric control cabinet for the compressor should be strategically located within a 5-meter radius of the compressor. Ensure the wiring from the compressor to this cabinet is carefully connected using threading pipes, routed securely underground. Once the electric control cabinet is correctly positioned, seamlessly connect the wiring terminals in the cabinet to the lines at the remote DCS, ensuring a smooth and efficient integration.
