MVR, or Mechanical Vapor Recompression, is a cutting-edge energy-saving advancement that dramatically reduces external energy needs by cleverly repurposing the secondary steam energy it initially creates. The core principle revolves around compressing the evaporator's secondary steam using a high-efficiency steam compressor. This process ingeniously transforms electrical energy into thermal energy, significantly elevating the pressure and temperature of the secondary steam. This heightened thermal energy is then recycled back into the evaporator, effectively heating the materials and inducing further evaporation. Through this innovative mechanism, the latent heat of the secondary steam's vaporization is fully recycled, offering a groundbreaking solution in energy efficiency.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, featuring an intricately designed compressor body, robust coupling, efficient gearbox, state-of-the-art lubrication system, powerful motor, sophisticated electric instruments, and an advanced anti-surge control system. Its design is not only compact but also optimized for effortless maintenance, ensuring peak performance and reliability.
3.3.1 Seamlessly integrate the heart of your system with precision. The compressor base should be meticulously placed on its foundation, supported by wedge-shaped shims to ensure perfect leveling and stability. These shims act as subtle yet powerful adjusters, bringing harmony and balance to your setup.
Alternately position two wedge-shaped irons, achieving the ideal level, then secure with spot welds at 4 to 5 stable points. These wedge irons, tailored to your unique situation, must have a refined, smooth contact surface to ensure even support. The bearing capacity should remain under 40Kg/cm, allowing for robust, yet gentle support.
These customized wedges, manufactured and installed by the user, must be crafted with precision to ensure a flawless finish and seamless contact. This ensures that each inclined plane offers even support, maintaining the integrity and performance of your equipment.
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Achieve unparalleled precision with the leveling process. Use a level to fine-tune and perfect the axial integrity, ensuring the axial level is 0.05/1000mm and horizontal level is 0.10/1000mm, to guarantee optimal performance and efficiency.
level of the unit is 0.10/1000mm.
3.3.3 Master the art of coupling alignment with these essential steps:
1) Ensure complete safety by turning off the main power supply;
2) Carefully remove the coupling shield to expose the intricate workings beneath;
3) Detach the diaphragm coupling's intermediate section for a clear pathway to alignment;
4) Inspect the motor's installation plane meticulously, ensuring it's free from any foreign objects, dust, or debris that could impede performance;
5) The motor bolt holes should exceed the bolt size, allowing ease of adjustment to the motor's position;
6) Arm yourself with a collection of pristine stainless steel gaskets. These should be devoid of any contaminants and perfectly flat, eschewing the use of elongated or thin gaskets that could disrupt the balance between motor and base;
7) Employ a dial indicator or a laser alignment meter, boasting a precision of 0.01mm, to achieve immaculate alignment (customer-provided);
8) Set up a robust bracket to support the dial indicator accurately, as illustrated below;
9) Utilize the motor wheel hub mounting bracket to delicately mount the dial indicator on the hub's perimeter, ensuring the probe makes contact with the compressor wheel hub's outer edge;
10) Through the strategic adjustment of bolts around the motor feet, align the compressor and motor center lines to perfection. Ensure the maximum deviation of the outer circle remains at 0.05mm, with the motor shaft center line slightly elevated above the low-speed compressor shaft center line, and maintain a coupling end face deviation of 0.03~0.05mm;
11) Secure the motor foot bolts firmly, revisiting and verifying the outer circle runout and coupling end face runout for assurance;;
12) Conclude with the installation of the coupling's intermediate section post motor idling test, solidifying your setup.
3.3.4 Elevate your setup by tightening the anchor bolts after the fine-tuning of alignment and levelness. Post mechanical operation, release these bolts momentarily, and secure them once more to ensure enduring stability.
3.3.5 Protect your investment with vigilance. The impeller, a high-speed marvel, must be safeguarded from any entering solids or liquids which could cause irreversible harm. Ensure the cleanliness and system-specified steam corrosion grade of inlet and outlet pipelines. Should pipelines fall short, rectify immediately to maintain optimum efficiency.Suggested: Implement solid-liquid separation devices, such as gas scrubbers or sedimentation tees, ahead of the straight pipe at the compressor inlet, to shield your system against potential contaminants.
3.3.6 Seamlessly install the compressor's inlet and outlet pipes, equipped with appropriate pipeline accessories as per the PI diagram. These pipelines should rest on separate brackets, ensuring their weight is not burdened on the compressor body, preserving longevity and performance.
3.3.7 Once the main fan and its associated equipment have been meticulously installed and the concrete foundation has achieved complete solidity, you can confidently proceed with the compressor's operational testing. This ensures everything is in prime condition for flawless performance.
3.3.8 For optimal efficiency, the electric control cabinet of the compressor should be strategically positioned within a convenient 5-meter radius of the compressor. The essential wiring connecting the compressor to its control cabinet is recommended to utilize a threading pipe for underground installation, ensuring both safety and neatness. Post-installation of the electric control cabinet, it is crucial to seamlessly connect its wiring terminals with the remote Distributed Control System (DCS) lines, guaranteeing cohesive and reliable operation.
