MVR, an abbreviation for Mechanical Vapor Recompression, stands as a groundbreaking energy-saving technology that dramatically curtails the need for external energy. By ingeniously reutilizing the secondary steam energy it generates, MVR optimizes efficiency like never before. The core principle rests in compressing the secondary steam—produced by the evaporator—using a high-efficiency steam compressor. This transformation of electrical energy into thermal energy results in elevated pressure and temperature. The renewed secondary steam is then cycled back to the evaporator to heat materials, instigating evaporation and achieving an extraordinary recycling of the latent heat of vaporization.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, comprising a compressor body, coupling, gearbox, lubrication system, motor, electric instruments, and an anti-surge control system. Its design boasts a compact structure that not only enhances its aesthetic appeal but also ensures ease of maintenance. This meticulously crafted system is tailored for optimal performance and reliability.
3.3.1 To set the stage for seamless operation, carefully position the compressor base onto the foundation and strategically place wedge-shaped shims beneath. These shims are pivotal for achieving the perfect level of the unit.
For optimal stability, alternate the positioning of two wedge-shaped irons and meticulously spot weld them at 4 to 5 points once leveling is complete.
Users are encouraged to custom manufacture and install these wedges based on specific requirements. Ensure that the contact surface is immaculately finished for uniform adhesion and support.
Pay special attention to the inclined plane’s even contact. Note that the bearing strength of each wedge iron must not exceed 40Kg/cm2).
3.3.2 Precision in leveling is paramount. Utilize a level to ascertain accuracy. The stringent leveling criteria require an axial level of 0.05/1000mm and a horizontal level of 0.10/1000mm.
Maintaining these precise measurements ensures optimal functionality and longevity of the unit.
3.3.3 Coupling alignment is an intricate process. Before you begin, ensure these prerequisites are strictly adhered to:
1) Deactivate the primary power source to ensure safety;
2) Dismantle the coupling shield to gain access;
3) Remove the diaphragm coupling’s intermediate section;
4) Verify the motor installation plane’s flatness, ensuring it is free from debris and impediments;
5) Design the motor bolt holes larger than the bolts themselves, allowing for loosening during adjustments;
6) Stock up on flat, attachment-free stainless steel gaskets. Avoid using elongated or skinny gaskets for motor-base adjustments;
7) Equip yourself with precision tools like a dial indicator or a laser alignment meter boasting 0.01mm accuracy (procure these tools independently);
8) Ready the bracket to support the dial indicator, depicted in the accompanying illustration;
9) Use the motor wheel hub mounting bracket for affixing a dial indicator on the wheel hub’s edge, placing the probe on the compressor wheel hub’s outer edge;
10) By deftly maneuvering the adjustment bolts around the motor feet, align the compressor and motor center lines. The outer circle’s deviation should not surpass 0.05mm, with the motor shaft center line slightly elevated compared to the compressor low-speed shaft.
11) Securely tighten the motor foot bolts, then assess the coupling’s outer circle and end face runout;;
12) Following a successful motor idling test, reinstall the coupling intermediate section.
3.3.4 Post-alignment, fortify the anchor bolts. Following the mechanical operation or trial run, release and re-tighten these bolts for reinforced stability.
3.3.5 The impeller, a high-speed marvel, is susceptible to damage from any solid or liquid intrusion. Thus, it’s imperative to maintain the cleanliness of the inlet and outlet pipelines aligned with the compressor, meeting the system's steam corrosion standards.In cases of non-compliance, remedial measures are essential. We advise installing solid-liquid separation apparatus like gas scrubbers or sedimentation tees before the compressor's inlet straight pipe.
3.3.6 Seamlessly install the compressor's inlet and outlet pipes, adhering to the PI diagram guidelines. Ensure that the pipelines, complete with essential accessories, are supported independently to prevent undue stress on the compressor body.
3.3.7 Once the main fan and its ancillary equipment have been meticulously installed and the concrete has reached full solidity, you are ready to embark on the all-important compressor operation test. This crucial stage ensures that all components are functioning harmoniously and are poised for peak performance.
3.3.8 For optimal efficiency and safety, position the electric control cabinet of the compressor within a strategic 5-meter radius of the compressor itself. The wiring should be elegantly threaded through piping that discreetly travels underground. Once the electric control cabinet is precisely positioned, proceed to seamlessly connect the wiring terminals within the cabinet to the remote DCS lines, ensuring a flawless integration between technology and infrastructure.
