MVR, which stands for Mechanical Vapor Recompression, is an innovative energy-saving technology that significantly reduces the demand for external energy. This remarkable system achieves efficiency by harnessing the power of secondary steam energy it produces. The core principle revolves around compressing secondary steam generated by the evaporator with a steam compressor of high energy efficiency. This process intricately converts electrical energy into thermal energy, resulting in elevated pressure and temperature of the secondary steam. Once the temperature rises, the secondary steam is seamlessly redirected back to the evaporator. Here, it works its magic by heating the materials, stimulating evaporation, and achieving the remarkable recycling of latent heat of vaporization from the secondary steam. This system truly embodies cutting-edge efficiency and sustainability.
The DM series Single-stage Geared Steam Compressor is an engineering marvel that primarily encompasses key components such as the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. This compressor is lauded for its compact structure, which not only facilitates space-saving deployment but also ensures ease of maintenance. Designed for reliability and performance, this system stands as a testament to precision engineering and superior functionality, making it an indispensable asset in modern industrial applications.
3.3.1 Begin by expertly positioning the compressor base securely on the foundation. Place precision wedge-shaped shims beneath the base to achieve flawless leveling.
Strategically arrange two wedge-shaped irons in an alternating pattern. Once perfectly leveled, skillfully spot weld the wedges at 4 to 5 points. This ensures stable support.
The user is responsible for crafting and installing wedges tailored to their specific conditions. The contact surface must be finely finished for uniform contact and maximum stability.
The bearing capacity of each wedge iron must not exceed 40Kg/cm2).
3.3.2 Employ a level to achieve meticulous alignment. The unit's axial level must be adjusted to a precision of 0.05/1000mm, while the horizontal level should be 0.10/1000mm.
Maintain these exacting standards for optimal performance and reliability.
3.3.3 Achieving perfect coupling alignment is essential for seamless operation. Prior to beginning, ensure the following safety and preparation steps:
1) Securely shut off the main power supply to prevent any accidental start-up.
2) Carefully remove the protective coupling shield to access the components.
3) Detach the diaphragm coupling's intermediate section with precision.
4) Thoroughly inspect the motor's installation plane to ensure it's free of debris, dirt, and unwanted materials.
5) Ensure the motor bolt holes are adequately sized larger than the bolts, allowing for necessary adjustments.
6) Prepare an ample supply of stainless steel gaskets to provide solid footing for the motor. They must be clean, flat, and free from any imperfections. Avoid using unsuitable long, thin gaskets.
7) Utilize either a dial indicator or a state-of-the-art laser alignment meter with a precision of 0.01mm. These tools are the customer's responsibility to provide.
8) Have the appropriate supporting bracket for the dial indicator ready, as depicted in the accompanying illustration.
9) Utilize a motor wheel hub mounting bracket to position a dial indicator on the hub edge, ensuring precision by placing the probe on the outer compressor wheel hub edge.
10) Adjust the bolts around the motor feet meticulously to align the compressor and motor center lines. Aim for a maximum outer circle deviation of 0.05mm, with the motor shaft center line slightly higher than the compressor low-speed shaft center line. The coupling end face should be between 0.03 and 0.05mm.
11) Securely fasten the motor foot bolts. Conduct a thorough review of the outer circle and end face runouts to ensure perfect alignment.;
12) Once verified, reinstall the coupling's intermediate section after completing the motor's idling test to ensure flawless integration.
3.3.4 Post alignment, tighten the anchor bolts securely. After conducting a mechanical trial operation, remember to loosen and re-tighten the bolts for optimal stability.
3.3.5 Prevent any damage to the high-speed rotating impeller by ensuring that no solid or liquid materials enter it. Maintain clean inlet and outlet pipelines per system steam corrosion grade requirements. Non-compliant pipelines must be modified accordingly.Consider installing solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the compressor inlet's straight pipe for enhanced protection.
3.3.6 Proceed to install the compressor's inlet and outlet pipes. Ensure all related pipeline accessories are fitted according to the precise PI diagram. The pipelines should be independently supported by a separate bracket, never imposing weight on the compressor body itself.
3.3.7 Once the main fan and all its ancillary equipment have been expertly installed and the concrete foundation has fully solidified, it's time to embark on the compressor operation test. This pivotal stage ensures that our Robust Power Frequency Compressor for Sugar Liquid Drying and Concentration is ready to perform at peak efficiency.
3.3.8 To ensure seamless operation, the electric control cabinet for the compressor should be strategically positioned within a 5-meter radius of the compressor itself. The connection between the compressor and the control cabinet must be meticulously arranged using threading pipes, which are to be routed underground for optimal protection and aesthetics. Once the electric control cabinet is securely in place, proceed to connect the wiring terminals in the cabinet with the lines at the remote Distributed Control System (DCS), ensuring a flawless integration.
