MVR, an acronym for Mechanical Vapor Recompression, represents an avant-garde, energy-efficient technology designed to significantly curtail the reliance on external energy sources. It ingeniously achieves this by harnessing and reusing the energy from the secondary steam it generates. At its core, this technology operates on a straightforward yet powerful principle: the secondary steam produced by the evaporator undergoes a transformation when compressed by a high-energy-efficient steam compressor. This process skillfully converts electrical energy into thermal energy, simultaneously elevating both the pressure and temperature of the secondary steam. This heated and pressurized steam is then redirected back into the evaporator, where it performs the dual function of heating the materials and inducing further evaporation. The result is a brilliant cycle of reutilization, effectively recycling the latent heat of vaporization from the secondary steam, thereby optimizing energy consumption and enhancing operational efficiency.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, ingeniously combining key components including the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an advanced anti-surge control system. This exceptional design is characterized by its compact structure, which not only ensures space efficiency but also facilitates effortless maintenance. With its cutting-edge features and robust construction, the DM series is crafted to deliver reliable performance, making it an indispensable asset in steam compression applications, where precision and durability are paramount.
3.3.1 Elegantly situate the compressor base on the foundation, carefully placing wedge-shaped shims beneath to achieve perfect leveling. These shims are essential for adjusting the unit's level.
Place two wedge-shaped irons alternately beneath the base. Once the unit is perfectly leveled, skillfully spot weld the wedge-shaped irons at 4 to 5 strategic points.
Craft the wedge to precision, tailored by the user for their specific situation, ensuring an impeccably finished contact surface for uniform contact on the inclined plane.
The bearing capacity of each wedge iron must not exceed an impressive 40Kg/cm2).
3.3.2 Utilize a level to achieve precise alignment. The unit's leveling standards are meticulous: the axial level is maintained at a tight 0.05/1000mm, with the horizontal level at a precise 0.10/1000mm.
This ensures optimal performance and reliability.
3.3.3 Center the coupling with precision. Before beginning alignment, adhere to these essential prerequisites:
1) Ensure safety by deactivating the main power supply;
2) Dismantle the coupling shield for unobstructed access;
3) Carefully remove the diaphragm coupling's intermediate section;
4) Inspect the motor installation plane meticulously, confirming it is free from debris, dirt, and any attachments;
5) Ensure the motor bolt hole is generously sized for the bolt, allowing easy adjustment of the motor's position;
6) Arm yourself with an abundance of pristine stainless steel gaskets for the motor's feet, ensuring no attachments are present and that they are perfectly flat. Avoid using long, slender gaskets for adjustment between the motor and the base;
7) Employ a dial indicator or a high-precision laser alignment meter with a remarkable accuracy of 0.01mm, prepared by the customer;
8) Prepare a sturdy bracket to support the dial indicator as illustrated in the accompanying figure;
9) Utilize the motor wheel hub mounting bracket to attach a dial indicator on the wheel hub's edge, with the probe gracefully positioned on the outer edge of the compressor wheel hub;
10) With deft adjustments to the bolts around the motor feet, align the compressor and motor center line impeccably (or per specific instructions), with a maximum deviation of the outer circle at a mere 0.05mm. Ensure the motor shaft center line is elevated above the compressor's low-speed shaft center line, with coupling end face precision at 0.03~0.05mm;
11) After achieving alignment, securely tighten the motor foot bolts and meticulously review the outer circle runout and end face runout of the coupling;
12) Conclude with the installation of the coupling's intermediate section post motor idling test.
3.3.4 Following the precise adjustment of 'levelness' and alignment, secure the anchor bolts firmly. After the trial operation or mechanical run, release and retighten the bolts to ensure enduring stability.
3.3.5 The impeller is a sophisticated, high-speed component; any intrusion of solids or liquids can cause irreversible damage to the compressor. Thus, it is imperative to maintain cleanliness in the inlet and outlet pipelines adhering to the system's steam corrosion grade standards. Pipelines failing to meet these criteria require immediate rectification.It is highly recommended to incorporate solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the straight pipe at the compressor's inlet.
3.3.6 Expertly install the compressor's inlet and outlet pipes. Ensure import and export pipelines are equipped with appropriate pipeline accessories as depicted in the PI diagram. The compressor's connected pipeline must be supported externally, never relying on the compressor's body for support.
3.3.7 Once the main fan and its accompanying equipment are meticulously installed and the concrete has fully set and solidified, it's time to initiate the compressor operation test. This pivotal phase ensures the seamless functioning of the Reliable Steam Compressor with Speed Regulation, crafted specifically for the precise needs of sugar liquid processing.
3.3.8 For optimal efficiency, the electric control cabinet should be strategically positioned within a 5-meter radius of the compressor. The connection to this vital cabinet from the compressor is to be executed through a threading pipe, expertly routed underground to maintain aesthetic and functional integrity. Upon securing the electric control cabinet, it is imperative to connect the wiring terminals meticulously inside it with the lines at the remote DCS, ensuring flawless operational synergy.
