MVR, an acronym for mechanical vapor recompression, represents a cutting-edge, energy-efficient innovation designed to dramatically diminish the reliance on external energy sources. This remarkable technology ingeniously repurposes the secondary steam energy it produces. The foundational principle revolves around the transformation of secondary steam, generated within the evaporator, using a high-efficiency steam compressor. This process masterfully converts electrical energy into valuable thermal energy, effectively increasing both the pressure and temperature of the secondary steam. Subsequently, the elevated steam returns to the evaporator, where it adeptly heats the materials, inducing evaporation and facilitating the continuous recycling of the latent heat of vaporization of the secondary steam.
The DM series Single-stage geard steam compressor is a marvel of engineering, encompassing a comprehensive assembly that includes the compressor body, coupling, gearbox, lubrication system, motor, electric instruments, and an advanced anti-surge control system. Its compact design ensures seamless integration and ease of maintenance, making it a convenient and efficient choice for modern industries.
3.3.1 The compressor base is placed with precision on the foundation. Ensure wedge-shaped shims are positioned under the base to fine-tune the level of the unit. The meticulous placement of these shims ensures optimal stability and performance.
Arrange two wedge-shaped irons alternately. Once the unit reaches perfect leveling, spot weld the irons at 4 to 5 points. This essential step guarantees the foundation's reliability, enhancing the unit's functionality.
The user is responsible for manufacturing and installing the wedges based on specific conditions. Ensure the contact surfaces are finely finished, assuring firm and even contact between inclined planes.
The bearing capacity of the wedge iron should not exceed 40Kg/cm to maintain structural integrity and safety standards.2).
3.3.2 Utilize a level tool to achieve precise leveling. The unit's axial level should be pinpoint accurate at 0.05/1000mm, while the horizontal level must meet the 0.10/1000mm requirement, ensuring impeccable balance.
level of the unit is 0.10/1000mm.
3.3.3 The coupling process requires accurate centering. Before commencing alignment, adhere to the following essential prerequisites:
1) Ensure the main power supply is completely turned off for safety.
2) Dismantle the coupling shield with care to access the internal components.
3) Remove the diaphragm coupling's intermediate section to prepare for the alignment.
4) Verify the motor installation plane's flatness, ensuring it is free from foreign objects, dirt, and any attachments.
5) The motor bolt holes should exceed the bolt size, allowing for easy adjustment of the motor position by loosening the bolts.
6) Have ample, high-quality stainless steel gaskets ready. These gaskets must be devoid of attachments and perfectly flat. Avoid using long, thin gaskets for adjustments between the motor and base.
7) Employ a dial indicator or a laser alignment meter with a 0.01mm precision, which the customer must provide, to ensure perfect alignment.
8) Prepare a sturdy bracket as illustrated below to support the dial indicator for accurate measurements.
9) Use a specialized motor wheel hub mounting bracket to secure a dial indicator on the wheel hub's edge, placing the probe on the compressor wheel hub's outer edge for precise readings.
10) Adjust the motor feet bolts carefully, aligning the compressor and motor center lines. The maximum deviation for outer circles should not exceed 0.05mm, ensuring the motor shaft center line is slightly elevated above the compressor low-speed shaft center line. Align the coupling end face within a 0.03~0.05mm range.
11) Secure the motor foot bolts firmly after alignment, and double-check the outer circle and end face runout of the coupling.;
12) After successfully conducting the motor idling test, reinstall the coupling's intermediate section to complete the setup.
3.3.4 Once the casing's 'levelness' and alignment are perfected, tighten the anchor bolts. Post mechanical or trial operations, it is crucial to loosen and retighten these bolts to ensure maximum security and performance.
3.3.5 The impeller, a high-speed, rotating marvel, must remain free from solids or liquids to prevent irreversible damage. Guarantee cleanliness in the inlet/outlet pipelines, complying with the steam corrosion grade standards. Pipelines failing to meet these standards must be rectified. It is advised to incorporate solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the straight pipe at the compressor inlet.ugested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Install the compressor's inlet and outlet pipes diligently. Ensure import/export pipelines are fitted with appropriate accessories per the PI diagram. Each pipeline must be supported independently, with its weight never burdening the compressor body, ensuring both safety and efficiency.
3.3.7 Once the primary fan and all its auxiliary equipment have been meticulously installed and the concrete foundation has completely cured, you can proceed with the operational test of the compressor. This ensures flawless performance and reliability of the High-Efficiency Steam Compressor with Split Base and Speed Regulation from NANTONG DART-RICH FAN CO.,LTD.
3.3.8 The electrical control cabinet for the compressor should be strategically positioned within a 5-meter radius of the compressor itself. For seamless integration, the wiring from the compressor to the control cabinet must be enclosed in a threading pipe that runs underground. Once the cabinet is firmly in place, seamlessly connect the wiring terminals in the electric control cabinet to the circuits at the remote DCS, ensuring efficient and effective control of the High-Efficiency Steam Compressor with Split Base and Speed Regulation by NANTONG DART-RICH FAN CO.,LTD.
