MVR, an abbreviation for Mechanical Vapor Recompression, stands as an innovative, energy-efficient marvel designed to significantly cut down the need for external energy sources. This ingenious technology works by repurposing the secondary steam energy it generates, thus showcasing a sustainable approach to energy use. The foundational concept is centered around the secondary steam produced by the evaporator. A high-energy efficiency steam compressor expertly compresses this steam, transforming electrical energy into thermal energy. As a result, both the pressure and temperature of the secondary steam increase, enabling it to return to the evaporator. This process seamlessly heats the materials and instigates evaporation, ultimately achieving a remarkable recycling of the latent heat of vaporization inherent in secondary steam.
The DM series Single-stage Geared Steam Compressor is a masterpiece of engineering, meticulously crafted to include a comprehensive array of components: the robust compressor body, a precise coupling, an efficient gearbox, an advanced lubrication system, a powerful motor, sophisticated electric instruments, and a state-of-the-art anti-surge control system. Its design is characterized by a compact structure that not only enhances its aesthetic appeal but also simplifies maintenance, making it a convenient choice for users seeking reliability and ease of use.
3.3.1 Position the entire compressor base on the foundation and place wedge-shaped shims beneath it to adjust the unit's level to perfection. This foundational step ensures stability and precision.
Expertly arrange two wedge-shaped irons alternately to achieve impeccable leveling. Securely spot weld these irons at 4 to 5 strategic points, setting the stage for seamless operations.
The user is tasked with crafting and installing the wedges tailored to their specific conditions, ensuring the contact surface is meticulously finished for complete and even contact of the inclined plane.
The bearing capacity of your wedge iron must not exceed the stringent threshold of 40Kg/cm², safeguarding the integrity and durability of the installation.2).
3.3.2 Achieve unparalleled precision using a level. The compressor's axial level requirement stands at a fine 0.05/1000mm, while the horizontal level must meet a precise 0.10/1000mm.
This attention to detail ensures uncompromised performance and longevity.
3.3.3 Attain perfect coupling alignment by confirming these vital prerequisites before commencing:
1) Ensure the main power supply is turned off, prioritizing safety above all else.
2) Carefully remove the coupling shield to reveal intricate components.
3) Detach the diaphragm coupling intermediate section with precision and care.
4) Verify the motor installation plane's flatness, ensuring it is free from any foreign objects, debris, or unwanted attachments.
5) Confirm the motor bolt hole diameter exceeds the bolt size to allow for convenient adjustments.
6) Prepare an ample supply of stainless steel gaskets to fit perfectly under the motor's foot, ensuring pristine conditions free of attachments or warps.
7) Equip yourself with a dial indicator or a state-of-the-art laser alignment meter boasting 0.01mm accuracy, indispensable tools for precise alignment.
8) Ready the supporting bracket for the dial indicator, following the model illustrated.
9) Utilize the motor wheel hub mounting bracket for optimal placement of the dial indicator on the compressor's wheel hub, ensuring measurements of unparalleled accuracy.
10) Fine-tune the motor's alignment using the adjustment bolts strategically positioned around the motor feet. The target is to bring the compressor and motor center line into perfect harmony, maintaining a maximum deviation of just 0.05mm.
11) Secure the motor foot bolts and revisit both the outer circle runout and end face runout of the coupling for assurance.;
12) Finally, mount the coupling intermediate section upon the satisfactory completion of the motor's idling test, ensuring flawless alignment.
3.3.4 Once the casing's levelness and alignment are impeccably adjusted, anchor bolts should be tightened. During mechanical operations, these bolts must be loosened and retightened to maintain optimal performance.
3.3.5 The impeller, a high-speed marvel, requires the utmost caution—any ingress of solids or liquids could spell irreversible harm. Thus, it's essential to maintain clean inlet and outlet pipelines, adherent to the system's steam corrosion grade. Any pathway falling short must be promptly upgraded.Incorporating solid-liquid separation equipment, like a gas scrubber or sedimentation tee, before the compressor's inlet straight pipe is highly recommended for added protection and efficiency.
3.3.6 Seamlessly integrate compressor inlet and outlet pipes, adhering to the PI diagram for accessory guidance. Ensure that the connected pipelines are supported independently and not burdened by the compressor, preserving its integrity and function.
3.3.7 Once the majestic main fan and its supportive ancillary equipment have been meticulously installed and the concrete foundation stands robust and solidified, you're ready to embark on the thrilling journey of conducting the compressor operation test.
3.3.8 The sophisticated electric control cabinet for the compressor demands strategic placement within a 5-meter radius from the compressor itself. Ensure seamless connectivity by using threading pipes for wiring, discreetly running underground for a sleek appearance. Once the electric control cabinet is securely in position, harmonize the system by linking the wiring terminals in the cabinet with the lines at the remote DCS, ensuring a seamless and efficient operation.
