MVR, or Mechanical Vapor Recompression, represents a groundbreaking, energy-efficient innovation designed to drastically cut down on the requirement for external energy. This is accomplished by ingeniously reutilizing the secondary steam energy it generates. The core principle at work here involves compressing the secondary steam produced by the evaporator using an exceptionally high-performance steam compressor. This process ingeniously transforms electrical energy into thermal energy, subsequently elevating both the pressure and temperature of the secondary steam. This heightened temperature and pressure enable the steam to return to the evaporator, effectively heating the materials and promoting further evaporation. This cycle ingeniously facilitates the recycling of the latent heat of vaporization within the secondary steam, optimizing energy use.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering that encapsulates advanced technology within a compact and easily maintained design. This impressive compressor system comprises several key components: a robust compressor body, an efficient coupling, a precision-engineered gearbox, a comprehensive lubrication system, a powerful motor, sophisticated electric instruments, and a highly responsive anti-surge control system. Together, these elements create a highly efficient, space-saving solution that's as easy to service as it is cutting-edge.
3.3.1 The foundation is the bedrock of stability for the Versatile Steam Compressor. Ensure the compressor base is integrally placed on it, with wedge-shaped shims expertly positioned underneath to meticulously adjust the unit's level.
Skillfully alternate two wedge-shaped irons to achieve impeccable leveling, then spot weld at 4 to 5 strategic points for optimal security. These wedges must be crafted by the user to fit the precise context, ensuring an immaculate contact surface.
3.3.1 cont'd: The contact surface must be finished to guarantee flawless interaction between inclined planes, ensuring that the wedge iron bears no more than 40Kg/cm.
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 The precision of leveling is crucial. Use a level to achieve an axial level tolerance of 0.05/1000mm and a horizontal level tolerance of 0.10/1000mm for the compressor unit.
The horizontal level of the unit is a precise 0.10/1000mm.
3.3.3 Achieving perfect alignment begins with centering the coupling. Prior to alignment, ensure the following preparatory steps are meticulously followed:
1) Ensure safety first by switching off the main power supply;
2) Carefully remove the coupling shield for unobstructed access;
3) Detach the diaphragm coupling intermediate section to prepare for precise alignment;
4) Thoroughly check the motor installation plane for smoothness and cleanliness, ensuring it is free from any debris or obstructions;
5) Ensure the motor bolt holes are larger than the bolts, allowing easy loosening for motor adjustments;
6) Have a sufficient supply of stainless steel gaskets ready, ensuring they are impeccably clean and flat. Avoid using elongated and thin gaskets that could compromise stability;
7) For precision alignment, utilize a dial indicator or a high-accuracy laser alignment meter with a precision of 0.01mm, prepared by you, our valued customer;
8) Prepare the bespoke bracket to support the dial indicator, as described in the accompanying diagram;
9) Install the motor wheel hub mounting bracket, designed to accommodate the dial indicator on the wheel hub’s edge, ensuring precise positioning of the dial indicator probe. This is critical for the compressor wheel hub alignment;
10) Through the careful adjustment of motor foot bolts, align the compressor and motor center lines as closely as possible, noting that the motor shaft center must surpass the compressor's low-speed shaft center by a margin. Maintain deviations within 0.05mm on the outer circle and 0.03~0.05mm for the coupling end face;
11) Conclude by firmly tightening the motor foot bolts and meticulously reviewing the outer circle runout and coupling end face runout, ensuring precision is maintained.;
12) Following a successful motor idling test, reinstall the coupling intermediate section with confidence.
3.3.4 After achieving ideal 'levelness' and alignment, secure the casing anchor bolts. Post mechanical operation or trial run, loosen and re-tighten bolts to reinforce structural integrity.
3.3.5 The impeller, a high-speed marvel, must remain free from solid or liquid incursions to avoid irreversible damage. Ensure all inlet and outlet pipelines meet the system's steam corrosion grade standards. Should they fall short, immediate rectification is paramount.Consider incorporating efficient solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, before the compressor inlet’s straight pipe for enhanced protection.
3.3.6 Strategically install the compressor inlet and outlet pipes. Follow the PI diagram for precise installation of pipeline accessories, ensuring the pipeline’s weight is independently supported by another bracket and not by the compressor itself.
3.3.7 Once the main fan and its associated equipment have been meticulously installed and the concrete has reached full solidity, you can initiate the compressor operation test to ensure optimal performance and reliability.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within 5 meters of the compressor itself. The connection between the compressor and the electric control cabinet should be established using threading pipes, which should be carefully routed underground. Once the electric control cabinet is securely in place, ensure that the wiring terminals in the cabinet are seamlessly connected with the lines at the remote Distributed Control System (DCS) to guarantee efficient communication and control.
