MVR, an acronym for Mechanical Vapor Recompression, stands as a groundbreaking energy-saving technology designed to significantly diminish the reliance on external energy sources. By harnessing and repurposing the energy generated from secondary steam, it ingeniously minimizes energy wastage. The core principle revolves around the transformation of secondary steam produced by the evaporator. This steam undergoes compression via a high-efficiency steam compressor, adeptly converting electrical energy into thermal energy. As a result, the pressure and temperature of the secondary steam elevate, allowing it to return to the evaporator to effectively heat materials and facilitate evaporation. This innovative process ensures the sustainable recycling of the latent heat of vaporization of secondary steam.
The DML series low temperature rise steam compressor is a marvel of engineering, meticulously constructed with a suite of primary components that include the compressor body, which comprises the volute, impeller, main shaft, bearing housing, and seal. Additionally, it is equipped with a coupling, motor, and an advanced electric instrument suite. Each element of its construction is chosen for its superior performance and reliability, ensuring the compressor operates with remarkable efficiency and precision.
3.3.1 The installation of the compressor base is pivotal for ensuring optimal performance. Carefully position the integrally designed base on the foundation. To achieve precise leveling, place wedge-shaped shims under the base strategically. These shims, essential for adjusting the unit's level, should be placed alternately. Once the unit is perfectly leveled, execute spot welding on the wedge-shaped iron at 4 to 5 points. It's important to note that the user is responsible for manufacturing and installing these wedges, tailored to the actual situation. The contact surfaces should be refined to ensure even contact across the inclined plane with a bearing capacity not exceeding 40 Kg/cm².
Place two wedge-shaped irons alternately, and, after the unit is leveled, secure them with spot welds at 4 to 5 key points. The wedges must be user-manufactured and installed based on the specific needs, guaranteeing that the contact surface is finished to facilitate even contact across the inclined plane. This ensures that the bearing capacity does not exceed 40 Kg/cm².
The wedge should be user-manufactured and installed according to actual conditions, ensuring the contact surface is finished for even contact across the inclined plane and that the bearing capacity of these wedges doesn't surmount 40 Kg/cm².
plane, ensuring that the wedge iron's carrying capacity remains under 40 Kg/cm².2).
3.3.2 Utilize a high-precision level to ascertain the unit's level. The stringent leveling requirements for this unit demand that the axial level be maintained at 0.05/1000mm, while the horizontal level should be at 0.10/1000mm.
level of the unit is meticulously maintained at 0.10/1000mm.
3.3.3 Precise coupling alignment is crucial. Prior to initiating the alignment process, ensure the following prerequisites are met:
1) Disconnect the main power supply to ensure safety;
2) Detach the coupling shield carefully;
3) Remove the intermediary section of the diaphragm coupling;
4) Verify the motor installation plane's flatness. It must be free from debris, dirt, and any unwanted residues;
5) Ensure the motor bolt holes are larger than the bolt size, allowing for bolt looseness to facilitate motor adjustments;
6) Have a sufficient supply of stainless steel gaskets ready to support the motor. These gaskets must be devoid of any contaminants and should be perfectly flat. Avoid using elongated or slender gaskets for motor-base adjustments;
7) Employ either a dial indicator or a laser alignment meter with a sensitivity of 0.01mm, which should be arranged by the customer;
8) Prepare a specialized bracket to support the dial indicator as depicted in the accompanying diagram;
9) Utilize the motor hub mounting bracket to secure a dial indicator on the wheel hub's edge, and position the dial indicator probe on the compressor wheel hub's outer edge;
10) By adjusting the motor feet's bolts, align the compressor and motor center lines meticulously. The maximum deviation for the outer circle is specified at 0.05mm, with the motor shaft center line positioned higher than the compressor's low-speed shaft center line. The coupling end face should register between 0.03mm and 0.05mm;
11) Firmly tighten the motor foot bolts, and then reassess both the outer circle and end face runout of the coupling;
12) Post motor idling test, reassemble the coupling's intermediate section.
3.3.4 After achieving precise alignment and levelness of the casing, securely tighten the anchor bolts. Following the mechanical or trial operation, it's imperative to first loosen and then re-tighten these bolts for assured stability.
3.3.5 The impeller is a highly sensitive, fast-rotating component. Any intrusion of solid or liquid matter can inflict irreversible damage on the compressor. Consequently, it's crucial to maintain the cleanliness of the inlet and outlet pipelines linked to the compressor. They must comply with the steam corrosion grade standards pertinent to the system. Pipelines not in alignment with these standards should be rectified immediately. It is recommended to incorporate solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, preceding the straight pipe at the compressor's inlet.
3.3.6 When installing the compressor's inlet and outlet pipes, adhere to the PI diagram to ensure the inclusion of all pertinent pipeline accessories. The pipeline connecting to the compressor must be independently supported by an additional bracket, ensuring that no weight is borne by the compressor body, thereby safeguarding its structural integrity.
3.3.7 Once the primary fan and its supplementary apparatus are securely installed, and the concrete has reached complete solidification, you are set to initiate the compressor's operational test. This crucial phase will ensure that all components are functioning harmoniously, paving the way for optimal performance of the Advanced Steam Compressor.
3.3.8 The installation of the compressor's electric control cabinet is recommended to be within a 5-meter radius of the compressor itself. For a seamless connection, ensure that the wiring from the compressor to the electric control cabinet is expertly housed within a threading pipe, discreetly routed underground. Post-installation, it is imperative to connect the wiring terminals within the electric control cabinet to the lines located at the remote DCS, ensuring an efficient and reliable communication network for the Advanced Steam Compressor's operation.
