MVR, which stands for Mechanical Vapor Recompression, is a groundbreaking energy conservation technology designed to dramatically lower your reliance on external energy sources by ingeniously recycling the secondary steam energy it produces. The core principle behind MVR is the transformation of secondary steam generated by the evaporator into a powerhouse of efficiency. This transformation is achieved by compressing the secondary steam through a high-performance steam compressor that adeptly converts electrical energy into thermal energy. As a result, this process elevates both the pressure and temperature of the secondary steam, which in turn returns to the evaporator. This return journey invigorates the materials, generating further evaporation, and effectively harnesses the latent heat of vaporization of the secondary steam, thus achieving a virtuous cycle of energy reuse.
The DM series Single-stage Geared Steam Compressor is a marvel of engineering, featuring a meticulously designed system that includes a robust compressor body, a reliable coupling, a precision-engineered gearbox, an efficient lubrication system, a powerful motor, advanced electric instrumentation, and a state-of-the-art anti-surge control system. Its compact structure ensures it is not only space-efficient but also incredibly easy to maintain, making it an ideal choice for optimal performance and long-term reliability.
3.3.1 For a seamless setup, precisely position the compressor base onto the foundation. Strategically place wedge-shaped shims underneath to fine-tune the unit's level.
Arrange two wedge-shaped irons in an alternating pattern. After perfecting the unit’s level, solidify the wedges with spot welds at 4-5 key points. These wedges should be
crafted and installed by the user, tailored to the specific conditions. Ensure that the contact surfaces are smoothly finished for consistent contact across the inclined
planes. Note that the bearing strength of each wedge iron should not exceed 40Kg/cm2).
3.3.2 Utilize a precision level to ensure balance. The unit's leveling criteria are: an axial level of 0.05/1000mm and a horizontal
level of 0.10/1000mm, ensuring impeccable precision.
3.3.3 Achieving coupling precision involves ensuring the following prerequisites before alignment:
1) Secure safety by turning off the main power supply;
2) Carefully remove the coupling shield to access components;
3) Detach the diaphragm coupling intermediate section;
4) Inspect the motor installation plane for flatness, ensuring it is free from debris, dirt, and foreign objects;
5) Ensure motor bolt holes exceed bolt size to allow adjustments; allow bolt loosening for motor positioning;
6) Stock up on stainless steel gaskets to support the motor base. These gaskets must be clean and flat, avoiding long thin gaskets between the motor and base;
7) Employ a dial indicator or laser alignment meter with precise accuracy of 0.01mm (provided by the customer);
8) Prepare a bracket for the dial indicator as illustrated below;
9) The motor wheel hub mounting bracket stabilizes a dial indicator on the hub edge, positioning the probe on the outer edge of the compressor hub;
10) Adjust bolts around motor feet to align the compressor and motor center lines precisely, allowing a maximum outer circle deviation of 0.05mm, ensuring the motor shaft center line sits higher than the compressor's low-speed shaft center line, with coupling end face deviations of 0.03~0.05mm;
11) Securely tighten the motor foot bolts, then meticulously review the outer circle and end face runout of the coupling;
12) Following the motor’s idle test, reassemble the coupling's intermediate section.
3.3.4 Post alignment and level adjustments, firmly secure the anchor bolts. After mechanical trials, loosen and retighten bolts for assurance.
3.3.5 As impellers operate at high speeds, prevent damage by ensuring the connected inlet and outlet pipelines remain pristine, conforming to the system's steam corrosion specifications. Non-compliant pipelines require prompt rectification. It's recommended to install solid-liquid separation devices (such as gas scrubbers or sedimentation tees) before the straight pipe at the compressor inlet.uggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Seamlessly install the compressor's inlet and outlet pipes. Ensure import and export pipelines are outfitted with necessary pipeline accessories according to the PI diagram. The supporting bracket must handle the pipeline's weight independently, keeping the compressor body unburdened.
3.3.7 Following the successful installation of the main fan along with its auxiliary equipment, and once the concrete has achieved full solidity, we can proceed to the exhilarating phase of conducting the compressor operation test. This crucial step ensures the optimal functioning and performance of your Advanced Overall Base Compressor for seamless vanadium extraction.
3.3.8 The electric control cabinet for the compressor should be strategically positioned within a convenient 5-meter radius of the compressor itself. To ensure a sleek and unobtrusive integration, the wiring from the compressor to the electric control cabinet should be expertly threaded through a pipe and placed underground. Once the electric control cabinet is securely in place, the next step involves the precise connection of the wiring terminals within the cabinet to the lines at the remote Distributed Control System (DCS), ensuring seamless communication and operation.
