MVR, standing for Mechanical Vapor Recompression, represents a cutting-edge, energy-efficient innovation designed to dramatically curtail reliance on external energy sources by ingeniously repurposing the secondary steam it generates. The foundational principle of this remarkable technology is rooted in the efficient compression of secondary steam produced by the evaporator. This is achieved through the utilization of high-efficiency steam compressors, which skillfully transform electrical energy into thermal energy. As a result, the pressure and temperature of the secondary steam are elevated, allowing the newly energized steam to return to the evaporator. This return cycle facilitates heating of materials, triggering further evaporation and thus, ingeniously recycling the latent heat of vaporization inherent in the secondary steam. This process not only boosts energy efficiency but also enhances the overall sustainability of the system.
The DM series Single-stage Geared Steam Compressor is thoughtfully engineered with an array of vital components, including the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. Its design boasts a compact structure, ensuring ease of maintenance and operational convenience. This meticulously crafted machine delivers reliable performance and is an exemplary model of modern engineering, tailored to meet the demands of efficient and seamless steam compression tasks.
3.3.1 Begin the installation by securely placing the compressor base on a solid foundation. Enhance stability by inserting wedge-shaped shims beneath the base to finely adjust the level of the unit.
Position two wedge-shaped irons in an alternating manner. Once the unit is perfectly leveled, spot weld the irons at 4 to 5 points. This ensures robust stability and precision alignment.
The wedge should be custom-made and meticulously installed by the user, tailored to the specific requirements of your setup. Ensure the contact surfaces are perfectly finished for optimal contact.
The inclined plane must offer even contact with a maximum bearing capacity of 40Kg/cm², ensuring the structural integrity and performance of your compressor.22.
3.3.2 Utilize a precision level to verify the unit's alignment. The exacting leveling criteria demand an axial level precision of 0.05/1000mm and a horizontal level of 0.10/1000mm for unparalleled accuracy.
For unmatched performance, adhere strictly to these leveling specifications, ensuring the utmost efficiency and safety of the compressor.
3.3.3 Precise coupling centering is paramount. Before embarking on alignment, ensure the following prerequisites are meticulously fulfilled:
1) Safeguard the setup by turning off the main power supply, ensuring a safe and secure alignment process.
2) Carefully remove the coupling shield, providing unimpeded access for precision alignment.
3) Detach the diaphragm coupling's intermediate section, making way for thorough inspection and adjustment.
4) Scrutinize the motor's installation plane for any obstructions or debris, guaranteeing a smooth and flawless mounting surface.
5) Ensure that the motor bolt holes exceed the bolt size to allow for precise adjustments of the motor position.
6) Arm yourself with ample stainless steel gaskets for motor foot coverage. Steer clear of long, thin gaskets for optimal adjustment integrity.
7) Leverage precision instruments, such as a dial indicator or laser alignment meter, with an accuracy of 0.01mm for precise alignment.
8) Prepare the requisite bracket to support the dial indicator, as shown in the accompanying diagram, for precise measurements.
9) Deploy the motor wheel hub mounting bracket for exact placement of the dial indicator on the wheel hub edge, ensuring accuracy in the compression process.
10) Adjust the motor feet bolts carefully, aligning the compressor and motor center lines. Precision is key, with outer circle deviation no greater than 0.05mm.
11) Secure the motor foot bolts firmly. Reassess both outer circle and end face runout of the coupling for optimal function and alignment.;
12) Following a successful motor idling test, reattach the coupling's intermediate section to complete the alignment process.
3.3.4 Post-adjustment, firmly secure the anchor bolts after aligning the casing. Conduct a trial operation, then retighten the bolts to ensure steadfast stability.
3.3.5 The impeller, a high-velocity component, must be protected from foreign solid or liquid intrusions that could cause irreversible damage.To safeguard the compressor, ensure connecting pipelines are spotless and adhere to steam corrosion standards. Consider incorporating solid-liquid separation equipment for added protection.
3.3.6 Attach compressor inlet and outlet pipes as per the PI diagram, ensuring pipelines are supported externally, never relying on the compressor body for support.
3.3.7 Once the main fan along with its ancillary equipment have been meticulously installed and the concrete base has reached full solidification, you are ready to proceed with the highly anticipated compressor operation test. This marks a critical milestone in ensuring optimal performance and reliability.
3.3.8 Position the electric control cabinet strategically within a 5-meter radius of the compressor, ensuring seamless integration. Utilize threading pipes to securely connect the wiring from the compressor to the control cabinet, discreetly running them underground for an immaculate setup. Once the control cabinet is firmly in place, expertly link the wiring terminals within the cabinet to the remote DCS lines, establishing a robust and efficient control network.
