MVR, which stands for Mechanical Vapor Recompression, represents a cutting-edge energy-saving technology designed to significantly reduce the need for external energy sources. This innovative process achieves efficiency by harnessing and reusing the secondary steam energy it generates. At its core, the principle involves the high-efficiency compression of secondary steam produced by the evaporator, using an advanced steam compressor. This transformation process converts electrical energy into thermal energy, resulting in increased pressure and temperature of the secondary steam. The elevated temperatures and pressures enable the secondary steam to return to the evaporator, where it effectively heats the materials, instigating evaporation. This cycle ingeniously recycles the latent heat of vaporization within the secondary steam, optimizing energy utilization and promoting a sustainable energy system.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, featuring a meticulously designed compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an anti-surge control system. Its compact structure not only ensures superior performance but also offers exceptional convenience in maintenance. Each component is crafted with precision, ensuring reliability and efficiency, making it an ideal choice for modern industrial applications.
3.3.1 Begin by placing the compressor base securely on the prepared foundation. Utilize wedge-shaped shims beneath the base for precision leveling.
Position two wedges in alternating sequence. Once the unit is level, expertly spot weld the wedges at 4 to 5 key points, ensuring stability.
The user should craft and position the wedge according to specific conditions, with the contact surface expertly finished for optimal contact.
The bearing capacity of the wedge iron should not exceed 40Kg/cm2).
3.3.2 Utilize a precision level tool to ensure the unit's exact leveling. The unit must meet these precise standards: an axial level of 0.05/1000mm and a horizontal level of 0.10/1000mm.
level of the unit is 0.10/1000mm.
3.3.3 Achieve perfect alignment of the coupling. Before proceeding, ensure the following important conditions are met:
1) Disengage the main power supply completely.
2) Gently remove the coupling shield for unobstructed access.
3) Carefully detach the diaphragm coupling's intermediate section.
4) Thoroughly inspect the motor installation surface for debris, dirt, or any foreign materials.
5) Ensure the motor bolt holes are ample in size to allow easy loosening and positioning of the motor.
6) Prepare an adequate quantity of flat, attachment-free stainless steel gaskets for proper motor footing. Avoid using overly long and thin shims for adjustments between the motor and base.
7) Equip yourself with a highly accurate dial indicator or laser alignment tool (0.01mm precision, self-supplied).
8) Ready a sturdy bracket for supporting the dial indicator, as depicted in the accompanying illustration.
9) Utilize the motor wheel hub mounting bracket to position the dial indicator precisely on the wheel hub's edge, ensuring the probe is perfectly placed on the compressor wheel hub's outer edge.
10) Adjust the motor feet's bolts meticulously to align the compressor and motor center lines. The optimal outer circle deviation is a mere 0.05mm (the motor shaft should be marginally higher than the compressor's low-speed shaft), with a coupling end face deviation of 0.03~0.05mm.
11) Securely tighten the motor foot bolts. Verify the coupling's outer circle and end face runouts to confirm precision.;
12) Once the motor has been tested at idle, carefully reinstall the coupling's intermediate section.
3.3.4 Post-levelness and alignment refinement, fasten the anchor bolts securely. After initial mechanical operation or trial runs, the bolts should be loosened and retightened to ensure stability.
3.3.5 The impeller operates at high speeds, necessitating strict avoidance of solid or liquid intrusion, which could cause irreversible damage. Ensure all connecting pipelines are immaculately clean and adhere to required steam corrosion standards. Pipelines that do not comply must be rectified promptly. We recommend installing solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the straight pipe leading to the compressor inlet.uggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 For compressor inlet and outlet pipe installation, adhere to the PI diagram for relevant pipeline accessories. Ensure that all pipeline connections to the compressor are independently supported by separate brackets, as the compressor body itself must not bear any additional weight.
3.3.7 Once the primary fan and its supporting equipment are securely stationed and the concrete foundation has reached full solidity, the stage is set for conducting the compressor operation test. This crucial step ensures peak performance and seamless integration of the entire system, ultimately paving the way for the efficient processing of sugar liquid concentration and drying.
3.3.8 It's essential to position the compressor's electric control cabinet within a convenient 5-meter proximity, ensuring optimal accessibility. The electrical connections between the compressor and the cabinet should be expertly laid out using threading pipes that run underground for a streamlined and safe setup. Once the electric control cabinet is firmly established, it's time to connect its wiring terminals with the remote DCS lines, crafting a network of precision and reliability.
